    In order to better understand the mechanism of soot formation (one of the most challenging problems in the study of hydrocarbon combustion chemistry), reliable rate constants for the key reaction steps involved in the formation and polymerization of aromatic hydrocarbons in the inception stage are required for kinetic modeling. In this DOE sponsored work, the authors have developed three new experimental methods: cavity ring-down (CRD) spectrometry, pyrolysis/Fourier transform infrared spectrometry (p/FTIRS) and pulsed laser photolysis/mass spectrometry (PLP/MS) for kinetic measurements of C{sub 6}H{sub 5} reactions pivotal to incipient soot formation chemistry. In addition, the authors have also carried out ab initio molecular orbital (MO) calculations for several key elementary combustion reactions relevant to soot formation. The results are briefly summarized in the report using selected examples for more detailed discussion. 84 refs.

    This final technical report describes results and findings from a research project to examine the role of microbial phosphohydrolase enzymes in naturally occurring subsurface microorganisms for the purpose of promoting the immobilization of the radionuclide uranium through the production of insoluble uranium phosphate minerals. The research project investigated the microbial mechanisms and the physical and chemical processes promoting uranium biomineralization and sequestration in oxygenated subsurface soils. Uranium biomineralization under aerobic conditions can provide a secondary biobarrier strategy to immobilize radionuclides should the metal precipitates formed by microbial dissimilatory mechanisms remobilize due to a change in redox state.

    The overall objective of the Chattanooga fuel cell demonstrations project was to develop and demonstrate a prototype 5-kW grid-parallel, solid oxide fuel cell (SOFC) system that co-produces hydrogen, based on Ion America’s technology. The commercial viability of the 5kW SOFC system was tested by transporting, installing and commissioning the SOFC system at the Alternative Energy Laboratory at the University of Tennessee – Chattanooga. The system also demonstrated the efficiency and the reliability of the system running on natural gas. This project successfully contributed to the achievement of DOE technology validation milestones from the Technology Validation section of the Hydrogen, Fuel Cells and Infrastructure Technologies Program Multi-Year Research, Development and Demonstration Plan. Results of the project can be found in the final technical report.

    OAK B202 Final Technical Report. The present generation of reactor analysis methods uses few-group nodal diffusion approximations to calculate full-core eigenvalues and power distributions. The cross sections, diffusion coefficients, and discontinuity factors (collectively called ''group constants'') in the nodal diffusion equations are parameterized as functions of many variables, ranging from the obvious (temperature, boron concentration, etc.) to the more obscure (spectral index, moderator temperature history, etc.). These group constants, and their variations as functions of the many variables, are calculated by assembly-level transport codes. The current methodology has two main weaknesses that this project addressed. The first weakness is the diffusion approximation in the full-core calculation; this can be significantly inaccurate at interfaces between different assemblies. This project used the nodal diffusion framework to implement nodal quasidiffusion equations, which can capture transport effects to an arbitrary degree of accuracy. The second weakness is in the parameterization of the group constants; current models do not always perform well, especially at interfaces between unlike assemblies. The project developed a theoretical foundation for parameterization and homogenization models and used that theory to devise improved models. The new models were extended to tabulate information that the nodal quasidiffusion equations can use to capture transport effects in full-core calculations.

    The two main objectives of this project were: 1) to develop and test technologies to harvest, transport, store, and separate corn stover to supply a clean raw material to the bioproducts industry, and 2) engineer fermentation systems to meet performance targets for lactic acid and ethanol manufacturers. Significant progress was made in testing methods to harvest corn stover in a “single pass” harvest mode (collect corn grain and stover at the same time). This is technically feasible on small scale, but additional equipment refinements will be needed to facilitate cost effective harvest on a larger scale. Transportation models were developed, which indicate that at a corn stover yield of 2.8 tons/acre and purchase price of $35/ton stover, it would be unprofitable to transport stover more than about 25 miles; thus suggesting the development of many regional collection centers. Therefore, collection centers should be located within about 30 miles of the farm, to keep transportation costs to an acceptable level. These collection centers could then potentially do some preprocessing (to fractionate or increase bulk density) and/or ship the biomass by rail or barge to the final customers. Wet storage of stover via ensilage was tested, but no clear economic advantages were evident. Wet storage eliminates fire risk, but increases the complexity of component separation and may result in a small loss of carbohydrate content (fermentation potential). A study of possible supplier-producer relationships, concluded that a “quasi-vertical” integration model would be best suited for new bioproducts industries based on stover. In this model, the relationship would involve a multiyear supply contract (processor with purchase guarantees, producer group with supply guarantees). Price will likely be fixed or calculated based on some formula (possibly a cost plus). Initial quality requirements will be specified (but subject to refinement).Producers would invest in harvest

    The Industrial Assessment Center program at North Carolina State University has conducted one hundred industrial assessments of small and medium sized manufacturers in North Carolina, South Carolina, and Virginia. Reports were submitted to each facility that included a brief description of the plant, historical energy use, and a technical analysis of potential energy efficiency savings, waste reduction, and productivity savings. Seven hundred thirty eight conservation measures were recommended with total annual cost savings in excess of $18 million. The NCSU IAC has worked with other government and private entities to deliver energy efficiency and conservation services. We have worked closely with the NCSU Industrial Extension Service, the Manufacturer’s Extension Partnership (MEP), and the North Carolina State Energy Office to provide follow-up technical help and financial assistance in implementing conservation recommendations. In addition to these organizations, the NCSU IAC has also worked with the NC Department of Pollution Prevention and Environmental Assistance, the NC Solar Center, Advanced Energy Corporation, Duke Power, Progress Energy, Dominion Power, and the City of Danville, Virginia. Eighteen undergraduate and twenty graduate students were exposed to a variety of manufacturing processes, trained on plant safety, and taught the use of various types of data collection equipment. The students performed technical analyses of each recommendation, computed the potential savings from engineering relations and collected data, estimated the cost from vendor information, and communicated the findings in a compact, well written report to the client. The students have also been exposed to a variety of business personnel, including corporate presidents, engineering managers, plant managers, plant engineers, facility maintenance staff, and production workers – each with a unique perspective on the challenges faced in a modern manufacturing facility.

    High-resolution tracking detectors based on Active Pixel Sensor (APS) have been valuable tools in Nuclear Physics and High-Energy Physics research, and have contributed to major discoveries. Their integration time, radiation length and readout rate is a limiting factor for the planed luminosity upgrades in nuclear and high-energy physics collider-based experiments. The goal of this program was to demonstrate and develop high-gain, high-resolution tracking detector arrays with faster readout, and shorter radiation length than APS arrays. These arrays may operate as direct charged particle detectors or as readouts of high resolution scintillating fiber arrays. During this program, we developed in CMOS large, high-resolution pixel sensor arrays with integrated readout, and reset at pixel level. Their intrinsic gain, high immunity to surface and moisture damage, will allow operating these detectors with minimal packaging/passivation requirements and will result in radiation length superior to APS. In Phase I, we designed and fabricated arrays with calorimetric output capable of sub-pixel resolution and sub-microsecond readout rate. The technical effort was dedicated to detector and readout structure development, performance verification, as well as to radiation damage and damage annealing.

    This project developed a new high-performance R-10/high SHGC window design, reviewed market positioning and evaluated manufacturing solutions required for broad market adoption. The project objectives were accomplished by: identifying viable technical solutions based on modeling of modern and potential coating stacks and IGU designs; development of new coating material sets for HM thin film stacks, as well as improved HM IGU designs to accept multiple layers of HM films; matching promising new coating designs with new HM IGU designs to demonstrate performance gains; and, in cooperation with a window manufacturer, assess the potential for high-volume manufacturing and cost efficiency of a HM-based R-10 window with improved solar heat gain characteristics. A broad view of available materials and design options was applied to achieve the desired improvements. Gated engineering methodologies were employed to guide the development process from concept generation to a window demonstration. The project determined that a slightly de-rated window performance allows formulation of a path to achieve the desired cost reductions to support end consumer adoption.

    New and novel material and process technologies applied in wind blade designs and production are critical to increasing the competitiveness of wind power generation against traditional sources of energy. In this project, through collaboration between PPG Industries and MAG Industrial Automation Systems, the potential of using automated manufacturing for the production of fiber glass composite wind blades was evaluated from both technical and economic points of view. Further, it was demonstrated that by modifying the standard blade raw material forms through the use of cost effective pre-impregnated rovings coupled with using an automated fiber placement machine to lay up the parts, it is possible to produce state of the art composite laminates with significantly improved mechanical performance and with higher processing rates than standard blade production technology allows for today, thereby lowering the cost of energy over turbine blades made using traditional processes and materials. In conformity with the scope of work of the submitted proposal, the project team completed each task and documented and reported its findings on the appropriate quarterly report submitted to the DOE project team. The activities and this report are divided into 5 subtasks: (1) Material Investigation - Reviews traditional materials and key specifications and testing methods; (2) Manufacturing and Automation - Identifies new candidate material forms and automated layup processes; (3) Process Development - Performs trials of candidate materials and processes; (4) Predictive Analysis - Assesses impact of new material forms and automated processes on a model blade design; and (5) Feasibility Assessment - Compares traditional manufacturing processes and materials to new candidate material forms and automated processes.

    In the last two dcades or so, many multiscale algorthms have been proposed to enable large scale computations which were thought as nearly intractable. For example, the fast multipole algorithm and other similar ideas have allowed to considerably speed up fundamental computations in electromagnetism, and many other fields. The thesis underlying this proposal is that traditional multiscale methods have been well-developed and it is clear that we now need new ideas in areas where traditional spatial multiscaling is ill-suited. In this context, the proposal argues that clever phase-space computations is bound to plan a crucial role in advancing algorithms and high-performance scientific computing. Our research past accomplishments have shown the existence of ideas beyond the traditional scale-space viewpoint such as new multiscale geometric representations of phase-space. We have shown that these clever representations lead to enhanced sparsity. We have shown that enhanced sparsity has significant important implications both for analysis, and for numerical applications, where sparsity allows for faster algorithms. We have implemented these ideas and built computational tools to be used as new building blocks of a new generation of wave propagation solvers. Finally, we have deployed these ideas into novel algorithms. In this last year, we assembled all these techniques and made significant progress in solving a variety of computational problems, which we then applied in selected areas of considerable scientific interest.

The objective of this project was to test the Plasma Pilot Plant capabilities in wood industry. The final goal of the project was to replace the current state-of-the-art, regenerative thermal oxidation (RTO) technology by Low-Temperature Plasma Technology (LTPT) in paper and wood industry for Volatile Organic Components (VOC) destruction in High Volume Low Concentration (HVLC) vent emissions. MetPro Corporation joined the team as an industrial partner from the environmental control business and a potential leader for commercialization. Concurrent Technology Corporation (CTC) has a separate contract with DOE for this technology evaluation. They prepared questionnaires for comparison of this technology and RTO, and made this comparison. These data are presented in this report along with the description of the technology itself. Experiments with the pilot plant were performed with average plasma power up to 3.6 kW. Different design of the laboratory and pilot plant pulsed coronas, as well as different analytical methods revealed many new peculiarities of the VOC abatement process.

    During the 1-year duration of this project a new Shortwave Spectrometer (SWS) was designed and developed for deployment at the Southern Great Plains Central Facility to measure zenith solar spectral radiance. The SWS is comprised of two Zeiss miniature monolithic spectrometers (MMS-1 and MMS-NIR) for visible and near-infrared detection in the wavelength range between 350 and 2250 nm. Spectral resolution is 8 nm for the MMS-1 and 12 nm for the MMS-NIR. The light collector is a narrow field of view (±1.5 º) collimator at the front end of a high-grade custom-made fiber optic bundle. The data acquisition and control system is a 933 MHz Pentium based PC in a PC104 format with a USB interface between the computer and the spectrometers. Spectral sampling rate is approximately 1 Hz. A prototype SWS was deployed at SGP in November and December 2004 and it collected zenith-sky solar spectra at 1 Hz continuously over a 29 day period. Prior to deployment it was calibrated and characterized at the NASA Ames Airborne Sensor Facility (ASF) using a 30 inch Integrating Sphere. The SWS was also calibrated using a portable 12 inch integrating sphere at the Central Facility. The testing and calibration procedures were developed during this implementation. The planning and scheduling for permanent installation of the new SWS as well as data processing, calibration, archiving, and distribution was conducted.

    This project sought to develop new means of creating variation in the structure of starch that accumulates in maize seeds, through manipulation of the enzyme starch synthase III (SSIII). The central hypothesis was that SSIII is responsible for construction of certain lengths of linear glucan chains within the major starch component amylopectin, and that manipulation of this enzyme could create new varieties of starch that might have novel utilities as a renewable resource. The hypothesis was proven to be true through analysis of the effects of maize du1- mutations, which affect the structure and function of SSIII. SSIII was found to be required for the formation for two distinct groups of chain lengths in maize amylopectin, specifically those containing 7-9 glucose units and those containing 37-55 glucose units. Decrease in the frequency of these chains, as compared to wild type, is accompanied by an increase in chains of 11-15 glucose units. A hypothesis consistent with these data is that one of the other SS isoforms produces chains in the range of 11-15 units, and these are then elongated by SSIII to the range of 37-55 units. In order to try to manipulate the activity of SSIII in novel ways, transgenic maize plants were constructed in which the presumed regulatory part of the protein was detached from the known catalytic region responsible for synthesis of linear glucan chains within starch. Three different transgenes were introduced into maize, each containing different truncated versions of SSIII. Transgenic plants were followed over several generations, and their structure of their starches were analyzed. Novel structures were in fact observed. Specifically, there was a large increase in the frequency of chains containing 9-15 glucose units as compared two wild type maize starch, and a decrease in the frequency of those with 18-30 units. These structures of starch are distinct from those that caused by null mutations that eliminate SSIII, indicated a novel

    This research consisted of a theoretical investigation of the properties of surface-based nanostructures, having as a main goal the deeper understanding of the atomic-scale mechanisms responsible for the formation and stability of such structures. This understanding will lead to the design of improved systems for applications in diverse areas such as novel electronic devices, sensors, field-effect transistors, substrates with enhanced hydro-phobic (water repelling) or hydro-philic (water absorbing) behavior for coatings of various surfaces used in bioengineering, flexible displays, organic photovoltaics, etc. The research consisted of developing new theoretical methodologies and applying them to a wide range of interesting physical systems. Highlights of the new methodologies include techniques for bridging different scales, from the quantum-mechanical electronic level to the meso-scopic level of large molecular structures such as DNA, carbon nanotubes and two-dimensional assemblies of organic molecules. These methodologies were successfully applied to investigate interactions between systems that are large on the atomic scale (reaching the scale of microns in length or milliseconds in time), but still incorporating all the essential elements of the atomic-scale structure. While the research performed here did not address applications directly, the implications of its finding are important in guiding experimental searches and in coming up with novel solutions to important problems. In this sense, the results of this work can be incorporated in the design of many useful applications. Specifically, in addition to elucidating important physical principles on how nano-structures are stabilized on surfaces, we have used our theoretical investigations to make predictions for useful applications in the following fields: a) we proposed new types of nanotubes that can overcome the limitations of the carbon nanotubes whose properties depend sensitively on the structure which

    concentrating photovoltaic applications thathave substantially higher efficiency than single substrate cells made of elemental semiconductors such as silicon. This task required the development of new cell bonding methods with excellent coupling of both photons and electrons between the sub-cells. To accomplish this, we developed (1) GaInN solar cells with enhanced performance by using quantum-well absorbers and front-surface optical texturing, (2) a hybrid "pillar-array" bond which uses an array of metal pillars for electrical coupling, and (3) a "hybrid moth-eye" optical coating which combines the benefits of nano-imprinted moth-eye coatings and traditional multilayer coatings. The technical effectiveness was assessed by measurement of the photovoltaic efficiency of solar cells made using these techniques; the ultrahigh efficiencies targeted by this work are of compelling economic value for concentrating photovoltaics.

    emissions are only observed in whistler spheromaks and FRCs but not in mirrors or asymmetric configurations lacking magnetic null lines. The collisionless electron energization in a toroidal null line usually produces non-Maxwellian distributions. Off the null axis electrons gain more perpendicular than parallel energy. Distributions with T{sub {perpendicular}} > T{sub {parallel}} lead to whistler instabilities which have been observed. A whistler spheromak is a source of high-frequency whistler emissions. These are usually small amplitude whistlers propagating in a complicated background magnetic field. The waves are emitted from a moving source. High frequency whistlers propagate faster than the spheromak, thus partly move ahead of it and partly in the reverse direction. In test wave experiments wave growth opposite to the direction of the hot electron flow has been observed, confirming that Doppler-shifted cyclotron resonance instabilities account for the emission process. Propagating whistler mirrors produce no significant instabilities except when they interact with other fields which exhibit null lines. For example, a whistler mirror has been launched against a stationary FRC, resulting in strong FRC heating and whistler instabilities. In the whistler mirror configuration the antenna near-zone field produces a toroidal null line outside the coil which can also become a source for whistler emissions. Finally, nonlinear EMHD research has been extended to initially unmagnetized plasmas where a new nonlinear skin depth has been discovered. When a small-amplitude oscillating magnetic field is applied to a plasma the field penetration is governed by the skin depth, collisional or collisionless depending on frequency, collision frequency and plasma frequency. However, when the magnetic field increases the electrons become magnetized and the field penetration occurs in the whistler mode if the cyclotron frequency exceeds the oscillating frequency. This phenomenon has been

    of Am, initially for the dhcp and the fcc surfaces, can and have provided us with valuable information about chemical bonding in Am and the transitions from f-electron delocalization to f-electron localization in trans-uranium compounds. In particular, a comparative study of the electronic structures of the Pu and Am surfaces using the techniques of all-electron modern density functional theory and beyond can provide significant information about the role of 5f electrons in bond formation as also the localization of the 5f electrons, matters of considerable controversies. The change from metallic 5f bonding into local-moment nonbonding configurations that takes place between Pu and Am is rather unique in the periodic table and is at the very heart of our understanding of electronic structure. We believe that, considering the narrow bandwidth of surface states, any transition from itinerant to localized behavior first takes place at the actinide surfaces with possible reconstructions.

  13. Chemical mechanistic approaches for the suppression of soot formation in the combustion of high energy density fuels. Final technical report

    Significant advantages can be gained by the use of high energy density fuels in volume limited applications. However, excessive soot formation that accompanies the combustion of these fuels presently limits their application. Fuel additive approaches prove attractive as they require minimal modifications to already existing equipment. In the present study, a variety of flame configurations were used to study the additive effects on soot formation. Through tests conducted on laminar diffusion flames carbon disulfide (CS2) and methanol (CH3OH) were found to be the most effective soot suppressants. Chemical interaction by either additive was found to far surpass the physical influences. However, the exact nature of the chemical action could not be established with the current set of experiments. Additionally, both of these additives were found to reduce soot formation in at least one high energy density fuel - quadricyclane (C7H8). To further validate this approach, studies were conducted using droplet flames and high-pressure spray flames.

    Soladigm's research has produced a fundamental improvement in the technology for dynamic windows by successfully transitioning a low-cost, high-performance dynamic glass fabrication process from a simple 2" research prototype into a full-scale manufacturing environment capable of producing commercial dynamic insulated glass units (IGUs), and developing and optimizing the production process to meet all specifications for mass commercial production. The technology developed under this project is a revolutionary process for fabricating electrochromic glass that today exceeds DOE's 2020 performance and reliability targets at a compelling consumer price point. Before this project, we had demonstrated 2" prototypes using our deposition process that met these performance targets. The goal of this project was to prove that we could transition this lab-scale process to a scalable, "inline" manufacturing process, leveraging existing manufacturing tools capable of achieving a commercially attractive pricepoint in the near-term. Under this project we demonstrated the technical effectiveness of our manufacturing process by achieving or exceeding all of our technical and performance targets for inline fabrication of electrochromic IGUs. These performance specifications exceed DOE's 2020 performance and reliability targets. We also demonstrated the economic feasibility of our manufacturing process by reaching an initial production process that will achieve our target costs, which are compatible with mass adoption.

The substrates simulating ground surfaces were concrete from a Kennedy Space Center launch pad, and steel covered with a protective ablative material representing a launch platform. In-situ instrumentation consisted of witness materials, thermocouples, air handlers, filters, and cascade impactors; remote instrumentation consisted of optical cameras and spectrometers. Test and analysis team members included the Naval Air Warfare Center Aircraft Division, Sandia National Laboratories (SNL), Alliant Techsystems, and the Johns Hopkins University. Test data were analyzed, reported, and delivered, including plume rise and transport captured on video. Derivation of the alumina particle size distributions formed the basis for condensing vapor and agglomeration estimates. Assessment of alumina mass in the plume, along with the surrogate fraction from filter forensics, provided an estimate of airborne surrogate mass. Technical interchange meetings were held with SNL and the Jet Propulsion Laboratory. Specifications for the fire environment were developed and delivered. A thermochemistry model that simultaneously provides the maximum temperature and heat flux was developed and delivered. An SPIE paper on 3D pyrometry of the fire was written and presented.

    OAK-B135 This NERI project, originally started as the Secure Transportable Autonomous Light Water Reactor (STAR-LW) and currently known as the International Reactor Innovative and Secure (IRIS) project, had the objective of investigating a novel type of water-cooled reactor to satisfy the Generation IV goals: fuel cycle sustainability, enhanced reliability and safety, and improved economics. The research objectives over the three-year (1999-2002) program were as follows: First year: Assess various design alternatives and establish main characteristics of a point design; Second year: Perform feasibility and engineering assessment of the selected design solutions; Third year: Complete reactor design and performance evaluation, including cost assessment These objectives were fully attained and actually they served to launch IRIS as a full fledged project for eventual commercial deployment. The program did not terminate in 2002 at the end of the NERI program, and has just entered in its fifth year. This has been made possible by the IRIS project participants which have grown from the original four member, two-countries team to the current twenty members, nine countries consortium. All the consortium members work under their own funding and it is estimated that the value of their in-kind contributions over the life of the project has been of the order of $30M. Currently, approximately 100 people worldwide are involved in the project. A very important constituency of the IRIS project is the academia: 7 universities from four countries are members of the consortium and five more US universities are associated via parallel NERI programs. To date, 97 students have worked or are working on IRIS; 59 IRIS-related graduate theses have been prepared or are in preparation, and 41 of these students have already graduated with M.S.

    Dynalene Inc has developed and patented a fuel cell coolant with the help of DOE SBIR Phase I and Phase II funding (Project DE-FG02-04ER83884). However, this coolant could only be produced in lab scale (500 ml to 2 L) due to problems in the optimization and scale-up of a nanoparticle ingredient. This project optimized the nanoparticle production process in 10 L and 100 L reactors (which translates to about 5000 gallons of coolant), optimized the filtration process for the nanoparticles, and develop a high throughput production as well as quality control method for the final coolant formulation. Scale-up of nanoparticle synthesis (using emulsion polymerization) is an extremely challenging task. Dynalene researchers, in collaboration with a university partner, identified all the parameters affecting the size, charge density and coagulation characteristics of the nanoparticles and then optimized these parameters to achieve the goals and the objectives of this project. Nanoparticle synthesis was demonstrated to be reproducible in the 10 L and 100 L scales.

    . Platform teams organize faculty and students for cross-disciplinary, systems-oriented research and collaborative learning. To date, nine platforms have been developed, although these will most likely be reorganized into a smaller number of broader topics. In the spring of 2004, BRT faculty initiated a regional partnership and collaborative learning program with colleagues at the University of Minnesota, Kansas State University, and South Dakota State University to develop distance education courses in biorenewable resources and technology. As a fledgling graduate program, the BRT graduate program didn’t have the breadth of resources to offer a large number of courses in biorenewables. Other schools faced a similar problem. The academic consortium as first conceived would allow students from the member schools to enroll in biorenewables courses from any of the participating schools, which would assure the necessary enrollment numbers to offer specialized course work. Since its inception, the collaborative curriculum partnership has expanded to include Louisiana State University and the University of Wisconsin. A second international curriculum development campaign was also initiated in the spring of 2004. In particular, several BRT faculty teamed with colleagues at the University of Arkansas, University of Washington, University of Gent (Belgium), National Polytechnic Institute of Toulouse (France), and Technical University of Graz (Austria) to develop an EU-US exchange program in higher education and vocational education/training (entitled “Renewable Resources and Clean Technology”).

    This report serves as the Final Report for Santa Barbara County’s Energy Efficiency and Conservation Block Grant (EECBG) BetterBuildings Neighborhood Program (BBNP) award from the U.S. Department of Energy (DOE). This report explains how DOE BBNP funding was invested to develop robust program infrastructure designed to help property owners complete energy improvements, thereby generating substantial outcomes for the local environment and economy. It provides an overview of program development and design within the grant period, program accomplishments and challenges to date, and a plan for the future sustainability of emPower, the County’s innovative clean energy and building efficiency program. During the grant period, Santa Barbara County’s emPower program primarily targeted 32,000 owner occupied, single family, detached residential homes over 25 years old within the County. In order to help these homeowners and their contractors overcome market barriers to completing residential energy improvements, the program developed and promoted six voluntary, market-based service areas: 1) low cost residential financing (loan loss reserve with two local credit unions), 2) residential rebates, 3) local customer service, 4) expert energy advising, 5) workforce development and training, and 6) marketing, education and outreach. The main goals of the program were to lower building energy use, create jobs and develop a lasting regional building performance market. These services have generated important early outcomes and lessons after the program’s first two years in service. The DOE BBNP funding was extended through October 2014 to enable Santa Barbara County to generate continued outcomes. In fact, funding related to residential financing remains wholly available for the foreseeable future to continue offering Home Upgrade Loans to approximately 1,300 homeowners.

    OAK B135 We have discovered that bacteria produce and emit the hydrocarbon isoprene (2-methyl-1,3-butadiene), and have suggested that if isoprene-producing enzymes and their genes can be harnessed, useful hydrocarbon-producing systems might be constructed. The main goal of the proposed work was to establish the biochemical mechanism and regulation of isoprene formation in the model bacterial system, Bacillus subtilis. In this 3-year project we (a) characterized the physiological regulation of isoprene formation in B. subtilis and its relationship to isoprene formation in plant chloroplasts; (b) analyzed genetic controls on isoprene formation in B. subtilis; and (c) developed models to explain the biochemical rationale for isoprene formation. We are also pursued (d) new methods for continuous measurement of isoprene release in bioreactors, and (e) determined the presence of isoprene-forming Bacillus on plant roots and used B. subtilis as a biocontrol agent for protection of plant roots from plant pathogenic bacteria. We have made significant advances in several areas. These include: (1) establishing the enzymatic basis of isoprene formation in B. subtilis, and demonstrating throughout growth in a bioreactor that isoprene synthase activity rises and falls with each of three peaks of isoprene release (i.e. it appears to be a regulated enzyme). (2) We have explored genetic aspects of isoprene formation, using gene disruption methods to greatly alter the patterns of isoprene formation in bioreactors. Analysis of these mutants and alteration of cellular levels of dimethylallyl diphosphate (DMAPP), the substrate for isoprene synthase, has led to the formulation of two models to explain why isoprene is formed: an isoprenoid overflow model and a signaling model. We have obtained compelling evidence that isoprene releases in bioreactors result from metabolic overflow. However, we have yet to determine the pattern of isoprene formation when these bacteria are grown in a more

    The Neutron and X-Ray Studies of Advanced Materials VII Symposium, held at the 2014, 143rd Annual Meeting of The Minerals, Metals, and Materials Society (TMS), brought together experts, young investigators, and students from this sub-discipline of materials science in order for them to share their latest discoveries and develop collaborations. This annual symposium, which is organized by The Minerals, Metals, and Materials Society, is an important event for this community of scientists. This year, over 100 high-level technical talks were delivered over the course of the four day event. In addition, the large number of students and young investigators in attendance ensured the maximum benefit to the next generation’s work force in this area of study. The science surrounding the utilization of neutrons and x-rays to study advanced materials is becoming increasingly important in increasing the understanding of how the exceptional materials properties of such materials arise. In particular, x-rays and neutrons can be used to visualize material structures at an extremely high resolution and in some cases, three dimensions—allowing unprecedented insights into the mechanisms governing certain materials properties such as strength and toughness. Moreover, some of these techniques allow materials to be visualized without damaging the material, approaches known as non-destructive evaluation or “NDE”. This allows materials to be studied in 3 dimensions while undergoing change in real time which represents an important (and long sought-after) advancement in materials science. The types of interactions afforded by this event are beneficial to society at large primarily because they provide opportunities for the leaders within this field to learn from one another and thus improve the quality and productivity of their investigations. Additionally, the presence of young investigators and students with technical interests in this field provides promise that the United

    The results of previous studies suggest that the use of hydrogen from natural gas might be an important first step toward a hydrogen economy based on renewables. Because of infrastructure considerations (the difficulty and cost of storing, transmitting and distributing hydrogen), hydrogen produced from natural gas at the end-user`s site could be a key feature in the early development of hydrogen energy systems. In the first chapter of this report, the authors assess the technical and economic prospects for small scale technologies for producing hydrogen from natural gas (steam reformers, autothermal reformers and partial oxidation systems), addressing the following questions: (1) What are the performance, cost and emissions of small scale steam reformer technology now on the market? How does this compare to partial oxidation and autothermal systems? (2) How do the performance and cost of reformer technologies depend on scale? What critical technologies limit cost and performance of small scale hydrogen production systems? What are the prospects for potential cost reductions and performance improvements as these technologies advance? (3) How would reductions in the reformer capital cost impact the delivered cost of hydrogen transportation fuel? In the second chapter of this report the authors estimate the potential demand for hydrogen transportation fuel in Southern California.

    This report covers the technical effort through February, 1989. This effort was directed towards the technology associated with the development of a large scale, long pulse DF-CO{sub 2} chemical laser. Optics damage studies performed under Task 1 assessed damage thresholds for diamond-turned salt windows. Task 2 is a multi-faceted task involving the use of PHOCL-50 for laser gain measurements, LTI experiments, and detector testing by LANL personnel. To support these latter tests, PHOCL-50 was upgraded with Boeing funding to incorporate a full aperture outcoupler that increased its energy output by over a factor of 3, to a full kilojoule. The PHOCL-50 carbon block calorimeter was also recalibrated and compared with the LANL Scientech meter. Cloud clearing studies under Task 3 initially concentrated on delivering a Boeing built Cloud Simulation Facility to LANL, and currently involves design of a Cold Cloud Simulation Facility. A Boeing IRAD funded theoretical study on cold cloud clearing revealed that ice clouds may be easier to clear then warm clouds. Task 4 involves the theoretical and experimental study of flow system design as related to laser beam quality. Present efforts on this task are concentrating on temperature gradients induced by the gas filling process. General support for the LPCL field effort is listed under Task 5, with heavy emphasis on assuring reliable operation of the Boeing built Large Slide Valve and other device related tests. The modification of the PHOCL-50 system for testing long pulse DF (4{mu}m only) chemical laser operation is being done under Task 6.

    This final report deals with the results of a 5-yr project for developing a more energy-efficient, environmentally friendly, less costly process for producing hot metal than current coke ovens and blast furnaces. In the process, iron ore pellets are smelted in a foamy slag created by reaction of coal char with molten slag to produce CO. The CO further reacts with oxygen, which also reacts with coal volatile matter, to produce the heat necessary to sustain the endothermic reduction reaction. The uncombusted CO and H{sub 2} from the coal are used to preheat and prereduce hematite pellets for the most efficient use of the energy in the coal. Laboratory programs confirmed that the process steps worked. Pilot plant studies were successful. Economic analysis for a 1 million tpy plant is promising.

    nanoporous alumina templates. In order to eliminate this problem, electrophoretic deposition was selected as the more appropriate technique, which involves the guided deposition of semiconductor nanoparticles in the presence of ultrasonic energy to form the crystalline nanowires. Extensive experimental research was carried out to optimize the process parameters for formation of crystalline nanowires. It was observed that the environmental bath temperature plays a critical role in determining the structural integrity of the nanowires and hence their lengths. Investigation was carried out for the formation of semitransparent ohmic contacts on the nanowires to facilitate photocurrent spectroscopy measurements as well as for solar cell implementation. Formation of such ohmic contacts was found to be challenging and a process involving mechanical and electrochemical polishing was developed to facilitate such contacts. The use of nanoporous alumina templates for the surface texturing of mono- and multi-crystalline solar cells was extensively investigated by electrochemical etching of the silicon through the pores of the nanoporous templates. The processes for template formation as well as etching were optimized and the alumina/silicon interface was investigated using capacitance-voltage characterization. The process developed was found to be viable for improving solar cell performance.

    Previous USDOE-funded geothermal studies have produced an extensive temperature gradient and heat flow data base for the State of Oregon. One of the important features identified as a result of these studies is a rapid transition from heat flow values on the order of 40 mW/m/sup 2/ in the Willamette Valley and Western Cascades to values of greater than or equal to100 mW/m/sup 2/ in the High Cascades and the eastern portion of the Western Cascades. These data indicate that the Cascade Range in Oregon has potential as a major geothermal province and stimulated much of the later work completed by government agencies and private industry. Additional data generated as a result of this grant and published in DOGAMI Open-File Report 0-86-2 further define the location and magnitude of this transition zone. In addition, abundant data collected from the vicinity of Breitenbush and Austin Hot Springs have permitted the formulation of relatively detailed models of these hydrothermal systems. These models are published in DOGAMI Open-File Report 0-88-5. Task 1.2 of the Deliverables section of Amendment M001 is fulfilled by DOGAMI publication GMS-48, Geologic map of the McKenzie Bridge quadrangle, Lane County, Oregon. This map was printed in October, 1988, and is part of the final submission to USDOE. 8 refs.

    Wind has provided energy for thousands of years: some of the earliest windmill engineering designs date back to ancient Babylonia and India where wind would be used as a source of irrigation. Today, wind is the quickest growing resource in Americas expanding energy infrastructure. However, to continue to positively diversify Americas energy portfolio and further reduce the countrys reliance of foreign oil, the industry must grow substantially over the next two decades in both turbine installations and skilled industrial manpower to support. The wind sector is still an emergent industry requiring maturation and development of its labor force: dedicated training is needed to provide the hard and soft skills to support the increasingly complex wind turbine generators as the technology evolves. Furthermore, the American workforce is facing a steep decline in available labor resources as the baby boomer generation enters retirement age. It is therefore vital that a process is quickly created for supporting the next generation of wind technicians. However, the manpower growth must incorporate three key components. First, the safety and technical training curriculum must be standardized across the industry - current wind educational programs are disparate and dedicated standardization programs must be further refined and implemented. Second, it is essential that the wind sector avoid disrupting other energy production industries by cannibalizing workers, which would indirectly affect the rest of Americas energy portfolio. The future wind workforce must be created organically utilizing either young people entering the workforce or train personnel emerging from careers outside of energy production. Third, the training must be quick and efficient as large amounts of wind turbines are being erected each year and this growth is expected to continue until at least 2035. One source that matches these three requirements is personnel transitioning from military service to the

    Since the development of new antibiotics is out-paced by the emergence of bacterial resistance to existing antibiotics, it is crucial to understand the genetic mechanisms underlying resistance existing antibiotics. At the center of this mystery is a poorly understood phenomenon, heteroresistance: the coexistence of multiple subpopulations with varying degrees of antibiotic resistance. A better understanding of the fundamental basis of heteroresistance could result in sorely needed breakthroughs in treatment options. This project proposed to leverage a novel microfluidic (microchemostat) technology to probe the heteroresistance phenomenon in bacteria, with the aim of restoring the efficacy of existing {beta}-lactam antibiotics. The clinically important bacteria Methicillin Resistant S. aureus (MRSA) was used as the test case of bacteria that exhibits antibiotic heteroresistance. MRSA is difficult to treat because it is resistant to all {beta}-lactam antibiotics, as well as other classes of antimicrobials. Whereas {beta}-lactams such as methicillin and oxacillin are the preferred antibiotics to treat S. aureus infections due to their efficacy and low side effects, accurate determination and use of oxacillin/methicillin dosage is hampered by heteroresistance. In fact, invasive MRSA infections now account for about 95,000 deaths per year, a number that exceeds the deaths due to either influenza or HIV (12). In some MRSA strains, two subpopulations of cells may coexist: both populations carry the mecA gene that confers resistance, but mecA is differentially expressed so that only a small number of cells are observed during in vitro testing. Why this occurs is not understood. Prior experiments have sought to explain this phenomenon with conflicting results, with technology being the primary barrier to test the system sufficiently. This is the final report on work accomplished under the Lab-wide LDRD project 09-LW-112. This project was awarded to Frederick Balagadde who

    The Bonneville Power Administration (BPA) contracted with the Pacific Northwest National Laboratory (PNNL) to provide technical analytical support for system-wide fish passage information (BPA Project No. 2006-010-00). The goal of this project was to produce rigorous technical analysis products using independent analysts and anonymous peer reviewers. This project provided an independent technical source for non-routine fish passage analyses while allowing routine support functions to be performed by other well-qualified entities. The Independent Technical Analysis Process (ITAP) was created to provide non-routine analysis for fish and wildlife agencies and tribes in particular and the public in general on matters related to juvenile and adult salmon and steelhead passage through the mainstem hydrosystem. The process was designed to maintain the independence of analysts and reviewers from parties requesting analyses, to avoid potential bias in technical products. The objectives identified for this project were to administer a rigorous, transparent process to deliver unbiased technical assistance necessary to coordinate recommendations for storage reservoir and river operations that avoid potential conflicts between anadromous and resident fish. Seven work elements, designated by numbered categories in the Pisces project tracking system, were created to define and accomplish project goals as follows: (1) 118 Coordination - Coordinate technical analysis and review process: (a) Retain expertise for analyst/reviewer roles.

    This three year project, initiated in 1987, involved the genetic effects of alpha radiations on Drosophila. This document represents the final technical report. Plutonium residue was used as the alpha source of radon gas. Spontaneous mutation frequency in the Drosophila stock was very low. In the experiments using alpha radiation from radon gas, radiation doses as low as 20R induced significant numbers of mutations, with higher numbers of mutations at higher doses. If X-ray induced mutation frequencies reported in the literature are used for comparison, it can be concluded that alpha radiation from radon gas induces at least 2 to 3 time more mutations in Drosophila.

    This is the final report of the FEL Design Group for the Technical Optimization Study for the FERMI{at}ELETTRA project. The FERMI{at}ELETTRA project is based on the principle of harmonic upshifting of an initial ''seed'' signal in a single pass, FEL amplifier employing multiple undulators. There are a number of FEL physics principles which underlie this approach to obtaining short wavelength output: (1) the energy modulation of the electron beam via the resonant interaction with an external laser seed (2) the use of a chromatic dispersive section to then develop a strong density modulation with large harmonic overtones (3) the production of coherent radiation by the microbunched beam in a downstream radiator. Within the context of the FERMI project, we discuss each of these elements in turn.

    Complex non-linear and dynamic processes lie at the heart of the planet formation process. Through numerical simulation and basic observational constraints, the basics of planet formation are now coming into focus. High resolution imaging at a range of wavelengths will give us a glimpse into the past of our own solar system and enable a robust theoretical framework for predicting planetary system architectures around a range of stars surrounded by disks with a diversity of initial conditions. Only long-baseline interferometry can provide the needed angular resolution and wavelength coverage to reach these goals and from here we launch our planning efforts. The aim of the Planet Formation Imager" (PFI) project is to develop the roadmap for the construction of a new near-/mid-infrared interferometric facility that will be optimized to unmask all the major stages of planet formation, from initial dust coagulation, gap formation, evolution of transition disks, mass accretion onto planetary embryos, and eventual disk dispersal. PFI will be able to detect the emission of the cooling, newlyformed planets themselves over the first 100 Myrs, opening up both spectral investigations and also providing a vibrant look into the early dynamical histories of planetary architectures. Here we introduce the Planet Formation Imager (PFI) Project (www.planetformationimager.org) and give initial thoughts on possible facility architectures and technical advances that will be needed to meet the challenging top-level science requirements.

    The objective of this work was to continue the development of the Herbert Easterly heater apparatus for vehicles, such as semi-trailer tractors in order to fully establish its technical feasibility and provide the basis for its commercialization. This heater is auxiliary to the vehicle`s primary heating system. With the engine off it heats both the vehicle engine to a temperature at which it starts easily and the vehicle passenger compartment. Specifically, this heater is automatically ignitable, operates directly from the vehicle diesel fuel supply and preheats the vehicle engine fuel prior to combustion. During the course of this work nine different versions of prototype heaters were designed, constructed and tested. All designs were based on the ideas and principles outlined in the Easterly patent. Each successive version incorporated design and fabrication improvements relative to the previous version. The final version, Prototype 9, utilized a multiple water jacket design to capture additional heat from the combustion gases prior to exhausting to the atmosphere. This final prototype exceeded the performance of a commercially available Webasto DBW-2010 using the same commercial burner as the one used in the Webasto unit. The time required to raise the heater fluid temperature by 120{degree}F was 23% less (20 minutes compared to 26 minutes) for Prototype 9 compared to the commercially available unit. In addition a prototype heat exchanger for preheating engine fuel was designed, fabricated and tested. It was also determined that the Prototype 9 auxiliary heater could operate at 85{degree}F for approximately 6 hours on a fully charged 12 volt marine battery rated to deliver 500 cold cranking amps.

    In March 1995 AISI completed a five-year, $60 million collaborative development program on Direct Steelmaking cost-shared by DOE under the Metals Initiative. This program defined an energy-efficient and environmentally-friendly technology to produce hot metal for steelmaking directly from coal and iron ore pellets without incurring the high capital costs and environmental problems associated with traditional coke oven and blast furnace technology. As it becomes necessary to replace present capacity, this new technology will be favored because of reduced capital costs, higher energy efficiency, and lower operating costs. In April 1994, having failed to move forward with a demonstration plant for direct ironmaking, despite substantial efforts by both Stelco and Geneva Steel, an alternative opportunity was sought to commercialize this new technology without waiting until existing ironmaking capacity needed to be replaced. Recycling and resource recovery of steel plant waste oxides was considered an attractive possibility. This led to approval of a ten-month, $8.3 million joint program with DOE on recycling steel plant waste oxides utilizing this new smelting technology. This highly successful trial program was completed in December 1994. The results of the pilot plant work and a feasibility study for a recycling demonstration plant are presented in this final technical report.

    The final technical report for the Pegasus plow, a stalk and root embedding apparatus, describes progress from the development stage to the product support stage. The US Department of Agriculture - Agriculture Research Service (ARS) is now in the second year of a three year study comparing the Pegasus to conventional tillage. So far, no downside has been with the Pegasus and the following benefits have been documented: (1) Energy savings of 65.0 kilowatt hours per hectare over conventional tillage. This is when the Pegasus plow is used to bury whole stalks, and represents a 70% savings over conventional tillage (92.5 kilowatt hours per hectare). (2) Four to seven fewer passes of tillage, depending on the particular situation. This represents a substantial time savings to farmers. (3) So far, no differences in cotton yields. Recent cotton boll counts in one study indicate a higher yield potential with the Pegasus. (4) No disease problems. (5) Significantly higher levels of organic matter in the soil. A hypothesis of the study is that whole stalk burial may reduce plant disease problems. This hypothesis has not yet been proven. (6) Significantly higher levels of nitrate nitrogen. Total nitrogen and ammonia nitrogen trended higher but were not significantly different. This shows that whole stalk burial does not adversely affect the nitrogen cycle in the soil and may actually improve it. The marketing support stage of the project is also described in the report.

  17. Final Technical/Scientific Report: Commodity Scale Thermostable Enzymatic Transformations

    James J. Lalonde; Brian Davison

    2003-08-30

    The conversion of corn starch to high fructose corn-syrup sweetener is a commodity process, producing over 3 billion kg/y. In the last step of the process, an enzyme catalyst is used to convert glucose to the much sweeter sugar fructose. Due to incomplete conversion in the last step, the syrup must be purified using a chromatographic separation technique, which results in equal quantities of water being added to the syrup, and finally the water must be evaporated (up to 1 lb of water/lb of syrup). We have estimated the energy requirement in the evaporation step to be on the order of 13 billion BTU's/y. This process inefficiency could be eliminated if a thermostable form of glucose isomerase (GI), the enzyme catalyst used in the final step, was developed. Our chosen strategy was to develop an immobilized form of the enzyme in which the protein is first crystallized and then chemically cross-linked to form an insoluble particle. This so-called cross-linked enzyme crystal (CLE C(reg. sign)) technology had been shown to be a powerful method for enzyme stabilization for several other protein catalysts. In this work we have developed more than 30 CLEC preparations of glucose isomerase and tested them for activity and stability. We found these preparations to be highly active, with a 10-50 fold rate per gram of catalyst increase over existing commercial catalysts. The initial rates were also higher at higher temperatures as expected, however the efficiency of the CLEC GI preparations unexpectedly rapidly decreased to a low constant value with use at the higher temperatures. At this point, the source of this activity loss is unclear, however during this loss, the catalyst is found to form a solid mass indicating either breakage of the chemical cross-links or simple aggregation of the particles. It is likely that the increased mass transfer resistance due to this agglomeration is a major component of the activity loss. This research suggests that one potentially beneficial

    2011-12-31

    The Legacy engine is a completely new design, transitional diesel engine, replacing the reciprocating engine with a rotary engine. The Legacy engine offers significant advances over conventional internal combustion engines in 1) power to weight ratio; 2) multiple fuel acceptance; 3) fuel economy; and 4) environmental compliance. These advances are achieved through a combination of innovative design geometry, rotary motion, aspiration simplicity, and manufacturing/part simplicity. The key technical challenge to the Legacy engine's commercialization, and the focus of this project, was the development of a viable roton tip seal. The PST concept for the roton tip seal was developed into a manufacturable design. The design was evaluated using a custom designed and fabricated seal test fixture and further refined. This design was incorporated into the GEN2.5A prototype and tested for achievable compression pressure. The Decision Point at the end of Phase 1 of the project (described below) was to further optimize the existing tip seal design. Enhancements to the tip seal design were incorporated into the GEN2.5B prototype and tested and evaluated using the iterative research strategy described below. Compression pressures adequate for compression ignition of diesel fuel were achieved, although not consistently in all combustion volumes. The variation in compression pressures was characterized versus design features. As the roton tip seal performance was improved, results pointed toward inadequate performance of the housing side seals. Enhancement of the housing side seal system was accomplished using a custom designed side seal test fixture. The design enhancements developed with the test fixture were also incorporated into the GEN2.5B prototype and tested and evaluated using the iterative research strategy described below. Finally, to simplify the requirements for the roton tip seals and to enhance the introduction and combustion of fuel, a flush-mount fuel injector was

    The operating and mass transfer characteristics of rotating foam metal beds were studied to determine the potential for flue gas desulfurization. This is a final technical report on the work supported by DOE {number_sign}FG22-87-PC79924. The report is divided into two sections, Part 1 deals primarily with the operating characteristics of rotating beds, and Part 2 covers the mass transfer characteristics of S0{sub 2} absorption in water-lime slurries. Rotating foam metal beds are in essence packed towers operated in high gravitational fields. The foam metal bed is in the form of a cylindrical donut, or torus, and is rotated to produced the high centrifugal forces. The liquid phase enters the bed at the inner surface of the torus and is pulled by the field through the bed. Gas flows countercurrent to the liquid. The bed packing can have a very large specific surface areas and not flood. Possible benefits include much smaller height of a transfer unit resulting in smaller equipment and supporting structures, reduced solvent inventory, faster response with improved process control, reduced pressure drop, and shorter startup and shut-down times. This work is concerned broadly with the operating characteristics of rotating beds, the objectives being to (1) determine the pressure drop through the rotating bed; (2) determine the power required to operate the beds, (3) investigate the residence time distribution of the liquid phase in the beds; and (4) determine the mass transfer coefficients of S0{sub 2} absorption. Three packings of differing specific surface areas were studied, with areas ranging from 656 to 2952 m{sub 2}/m{sub 3}. Liquid flow rates to 36 kg/s*m{sub 2}, gas flow rate to 2.2 kg/s*m{sub 2}, and gravitational fields to 300 g were covered in this study.

    2007-06-10

    This study was conducted to evaluate the technical feasibility of using pressurized oxyfuel, the ThermoEnergy Integrated Power System (TIPS), to recover energy from biomass. The study was focused on two fronts—computer simulation of the TIPS plant and corrosion testing to determine the best materials of construction for the critical heat exchanger components of the process. The goals were to demonstrate that a successful strategy of applying the TIPS process to wood waste could be achieved. To fully investigate the technical and economic benefits of using TIPS, it was necessary to model a conventional air-fired biomass power plant for comparison purposes. The TIPS process recovers and utilizes the latent heat of vaporization of water entrained in the fuel or produced during combustion. This latent heat energy is unavailable in the ambient processes. An average composition of wood waste based on data from the Pacific Northwest, Pacific Southwest, and the South was used for the study. The high moisture content of wood waste is a major advantage of the TIPS process. The process can utilize the higher heating value of the fuel by condensing most of the water vapor in the flue gas and making the flue gas a useful source of heat. This is a considerable thermal efficiency gain over conventional power plants which use the lower heating value of the fuel. The elevated pressure also allows TIPS the option of recovering CO2 at near ambient temperatures with high purity oxygen used in combustion. Unlike ambient pressure processes which need high energy multi-stage CO2 compression to supply pipeline quality product, TIPS is able to simply pump the CO2 liquid using very little auxiliary power. In this study, a 15.0 MWe net biomass power plant was modeled, and when a CO2 pump was included it only used 0.1 MWe auxiliary power. The need for refrigeration is eliminated at such pressures resulting in significant energy, capital, and operating and maintenance savings. Since wood

    This project contributed significantly to the development of new codes and standards, both domestically and internationally. The NHA collaborated with codes and standards development organizations to identify technical areas of expertise that would be required to produce the codes and standards that industry and DOE felt were required to facilitate commercialization of hydrogen and fuel cell technologies and infrastructure. NHA staff participated directly in technical committees and working groups where issues could be discussed with the appropriate industry groups. In other cases, the NHA recommended specific industry experts to serve on technical committees and working groups where the need for this specific industry expertise would be on-going, and where this approach was likely to contribute to timely completion of the effort. The project also facilitated dialog between codes and standards development organizations, hydrogen and fuel cell experts, the government and national labs, researchers, code officials, industry associations, as well as the public regarding the timeframes for needed codes and standards, industry consensus on technical issues, procedures for implementing changes, and general principles of hydrogen safety. The project facilitated hands-on learning, as participants in several NHA workshops and technical meetings were able to experience hydrogen vehicles, witness hydrogen refueling demonstrations, see metal hydride storage cartridges in operation, and view other hydrogen energy products.

    This research adds to the understanding of the areas of residual starch and biomass conversion to alcohol, by providing data from pilot plant equipment of larger scale than the minimum required to give commercially scalable data. Instrumentation and control is in place to capture the information produced, for economic and technical evaluation. The impact of rheology, recycle streams, and residence time distributions on the technical and economic performance can be assessed. Various processes can be compared technically and economically because the pilot plants are readily modifiable. Several technologies for residual starch yield improvement have been identified, implemented, and patent applications filed. Various biomass-to-ethanol processes have been compared and one selected for technical optimization and commercialization. The technical and economic feasibility of the current simplified biomass conversion process is being confirmed by intensive pilot plant efforts as of this writing. Optimization of the feedstock handling and pretreatment is occurring to increase the alcohol yield above the minimum commercially viable level already demonstrated. Samples of biomass residue and reactor blowdown condensate are being collected to determine the technical and economic performance of the high-water-recycle waste treatment system being considered for the process. The project is of benefit to the public because it is advancing the efforts to achieve low-cost fermentable substrates for conversion to transportation fuels. This process combines the hydrolysis of agricultural residues with novel enzymes and organisms to convert the sugars released to transportation fuels. The process development is taking place at a scale allowing commercial development to proceed at a rapid pace.

    A Midwest Appropriate Technology Grant was awarded to determine the technical and economic feasibility of producing mineral-fiber insulation directly from extensive deposits of basaltic sand produced during former mining and milling operations in the Keweenaw Peninsula region of Michigan's Upper Peninsula. The amounts of local basaltic sands available and representative chemical compositions were determined. The variation of viscosity with temperature and chemical composition was estimated. Samples were melted and either pulled or blown into fiber. In all cases fiber could be made with a reasonable tensile strength to ensure usefulness. It was concluded that it was technically feasible to produce fibers from basaltic stamp sands of the Upper Peninsula of Michigan. A technical feasibility study using published data, a cost and design analysis of a basalt fiber production plant, a market survey of fiber needs, and an economic analysis for investing in a basalt fiber venture was undertaken. These studies concluded that the local production of basaltic insulation was both feasible and economically reasonable. It was suggested that the plant be located in a region of greater population density with lower utility costs. A representative one-third of these studies is included as appendices A, B, C, and D.

SELF is a 501(c)(3) and a certified Community Development Financial Institution (CDFI). SELF is a community-based lending organization that operates the Clean Energy Loan Program, which focuses on improving the overall quality of life of underserved populations in Florida with an emphasis on home energy improvements and cost-effective renewable energy alternatives. SELF was launched in 2010 through the creation of the non-profit organization and with a $2.9 million Energy Efficiency and Conservation Block (EECBG) grant from the U.S. Department of Energy (DOE). SELF has its main office and headquarters in St. Lucie County, in the region known as the Treasure Coast in East-Central Florida. St. Lucie County received funding to create SELF as an independent non-profit institution, outside the control of local government. This was important for SELF to create its identity as an integral part of the business community and to help in its quest to become a Community Development Financial Institution (CDFI). This goal was accomplished in 2013, allowing SELF to focus on its mission to increase energy savings while serving markets that have struggled to find affordable financial assistance. These homeowners are most impacted by high energy costs. Energy costs are a disproportionate percentage of household expenses for low to moderate income (LMI) households. Electricity costs have been steadily rising in Florida by nearly 5% per year. Housing in LMI neighborhoods often includes older inefficient structures that further exacerbate the problem. Despite the many available clean energy solutions, most LMI property owners do not have the disposable income or equity in their homes necessary to afford the high upfront cost of energy

    This binary plant is the first high-output refrigeration based waste heat recovery cycle in the industry. Its working fluid is environmentally friendly and as such, the permits that would be required with a butane based cycle are not necessary. The unit is modularized, meaning that the unit’s individual skids were assembled in another location and were shipped via truck to the plant site. This project proves the technical feasibility of using low temperature brine The development of the unit led to the realization of low temperature, high output, and environmentally friendly heat recovery systems through domestic research and engineering. The project generates additional renewable energy for Nevada, resulting in cleaner air and reduced carbon dioxide emissions. Royalty and tax payments to governmental agencies will increase, resulting in reduced financial pressure on local entities. The major components of the unit were sourced from American companies, resulting in increased economic activity throughout the country.

    1997-07-01

    The Sarah Lawrence College Human Genetics Program received Department of Energy funding to offer a continuing medical education workshop for genetic counselors in the New York metropolitan area. According to statistics from the National Society of Genetic Counselors, there are approximately 160 genetic counselors working in the tri-state area (New York, New Jersey, and Connecticut), and many of them had been working in the field for more than 10 years. Thus, there was a real need to offer these counselors an in-depth opportunity to learn the specifics of the major advances in molecular genetics, and, in particular, the new approaches to diagnostic testing for genetic disease. As a result of the DOE Award DE-FG02-95ER62048 ($20,583), in July 1995 we offered the {open_quotes}Workshop on Molecular Methods for Genetic Diagnosis{close_quotes} for 24 genetic counselors in the New York metropolitan area. The workshop included an initial review session on the basics of molecular biology, lectures and discussions on past and current topics in molecular genetics and diagnostic procedures, and, importantly, daily laboratory exercises. Each counselor gained not only background, but also firsthand experience, in the major techniques of biochemical and molecular methods for diagnosing genetic diseases as well as in mathematical and computational techniques involved in human genetics analyses. Our goal in offering this workshop was not to make genetic counselors experts in these laboratory diagnostic techniques, but to acquaint them, by hands-on experience, about some of the techniques currently in use. We also wanted to provide them a technical foundation upon which they can understand and appreciate new technical developments arising in the near future.

    Each of the two field test bits showed some promise though their performances were less than commercially acceptable. The Ohio test bit ran just over 3000 feet where about 4000 is considered a good run but it was noted that a Varel bit of the same type having a standard O ring seal was completely worn out after 8-1/2 hours (1750 feet drilled). The Texas test bit had good seal-bearing life but was the wrong cutting structure type for the formation being drilled and the penetration rate was low.

    The study is the preliminary evaluation of magnetically levitated ground transportation systems (MAGLEV). The evaluation focuses on using the New York State Thruway right-of-way in combination with MAGLEV systems currently in development in Germany and Japan and those proposed for development in the United States. The Energy Authority's goal in cosponsoring the study was to determine if MAGLEV offered the potential to meet future New York State transportation demands cost-effectively, and to evaluate the benefits that the State might expect from supporting MAGLEV technology development and system implementation. According to the preliminary report, substantial economic benefits could accrue to the State through MAGLEV-related research, development, manufacturing and construction. Implementation would have a favorable impact on issues related to transportation, the environment and energy conservation. With the exception of the German Transrapid system, developing a domestic prototype MAGLEV vehicle would take seven to nine years; no insurmountable technical barriers are apparent. EMF shielding (electromagnetic fields) is, however, a concern. It will cost an estimated $1 billion to develop a new MAGLEV system design; however, innovative designs may reduce the price.

    The Government Maglev System Assessment Team operated from 1991 to 1993 as part of the National Maglev Initiative. They assessed the technical viability of four US Maglev system concepts, using the French TGV high speed train and the German TR07 Maglev system as assessment baselines. Maglev in general offers advantages that include high speed potential, excellent system control, high capacity, low energy consumption, low maintenance, modest land requirements, low operating costs, and ability to meet a variety of transportation missions. Further, the US Maglev concepts could provide superior performance to TR07 for similar cost or similar performance for less cost. They also could achieve both lower trip times and lower energy consumption along typical US routes. These advantages result generally from the use of large gap magnetic suspensions, more powerful linear synchronous motors and tilting vehicles. Innovative concepts for motors, guideways, suspension, and superconducting magnets all contribute to a potential for superior long term performance of US Maglev systems compared with TGV and TR07.

    The Georgia Tech Research Institute (GTRI) investigated potential applications of millimeter wave (MMW) sources with peak powers on the order of a gigawatt. This power level is representative of MMW devices such as the free electron laser (FEL) and the cyclotron auto-resonance maser (CARM) that are under development at the Lawrence Livermore National Laboratory (LLNL). In addition to determining the technical requirements for these applications, the investigation considered potential users and how a high power MMW system would expand their current capabilities. Two of the more promising applications were examined in detail to include trade-off evaluations system parameters. The trade-off evaluations included overall system configuration, frequency and coherence, component availability, and performance estimates. Brainstorming sessions were held to try and uncover additional applications for a gigawatt MMW source. In setting up guidelines for the session, the need to attempt to predict applications for the years 2000 to 2030 was stressed. Also, possible non-DoD applications needed to be considered. While some of these applications could not in themselves justify the costs involved in the development of the radar system, they could be considered potential secondary applications of the system. As a result of the sessions, a number of interesting potential applications evolved including: space object identification; low angle tracking; illuminator for space-based radar; radio astronomy; space vehicle navigation; space debris location; atmospheric research; wind shear detection; electronic countermeasures; low observable detection; and long range detection via ducting.

    1994-03-01

    The Modular Electric Vehicle Program (MEVP) was an EV propulsion system development program in which the technical effort was contracted by DOE to Ford Motor Company. The General Electric Company was a major subcontractor to Ford for the development of the electric subsystem. Sundstrand Power Systems was also a subcontractor to Ford, providing a modified gas turbine engine APU for emissions and performance testing as well as a preliminary design and producibility study for a Gas Turbine-APU for potential use in hybrid/electric vehicles. The four-year research and development effort was cost-shared between Ford, General Electric, Sundstrand Power Systems and DOE. The contract was awarded in response to Ford`s unsolicited proposal. The program objective was to bring electric vehicle propulsion system technology closer to commercialization by developing subsystem components which can be produced from a common design and accommodate a wide range of vehicles; i.e., modularize the components. This concept would enable industry to introduce electric vehicles into the marketplace sooner than would be accomplished via traditional designs in that the economies of mass production could be realized across a spectrum of product offerings. This would eliminate the need to dedicate the design and capital investment to a limited volume product offering which would increase consumer cost and/or lengthen the time required to realize a return on the investment.

    This is the ``seventh`` and final Quarterly Report under the scope of work for cooperative agreement between the Western Interstate Energy Board and the US Department of Energy. The report covers the period January--March 1993. The cooperative agreement was to expire in June 1992, but DOE granted an extension through March 24, 1993. Since this is the last Quarterly Report under the expired cooperative agreement, most tasks are noted as being completed. Two final items, however, will soon be sent to DOE -- final minutes from the March 9--11 High- Level Radioactive Waste Committee meeting, and the Year-End Technical Report. Some highlights from the quarter: The Committee decided on a preferred format for the revised Spent Fuel and High-Level Radioactive Waste Transportation Primer. The document would be 100- 200 pages, accompanied by a series of white papers on key transportation elements. A 25--30 page handbook for educating western state elected officials would also be prepared. On March 24, the Committee sent a letter to DOE commenting on the Near-Site Transportation Infrastructure report findings. The Committee is concerned that infrastructure limitations may limit the rail shipping option in many instances, even after upgrades have been implemented. The NSTI findings may also have significant relevance to the decision to develop multi-purpose canisters. On April 1, the Committee sent DOE the white paper, Transportation Implications of Various NWPA Program Options, which determined that DOE cannot develop a national transportation system by 1998 for shipments to an MRS or other federal storage facility.

    In the early stages of this DOE-funded research project, we sought to prepare and study a well-defined nickel-alkyl complex containing tridentate nitrogen donor ligands. We found that reaction of (TMEDA)NiMe2 (1) with terpyridine ligand cleanly led to the formation of (terpyridyl)NiMe (2), which we also determined to be an active alkylation catalyst. The thermal stability of 2 was unlike that seen for any of the active pybox ligands, and enabled a number of key studies on alkyl transfer reactions to be performed, providing new insights into the mechanism of nickel-mediated alkyl-alkyl cross-coupling reactions. In addition to the mechanistic studies, we showed that the terpyridyl nickel compounds can catalytically cross-couple alkyl iodides in yields up to 98% and bromides in yields up to 46 %. The yields for the bromides can be increased up to 67 % when the new palladium catalyst [(tpy’)Pd-Ph]I is used. The best route to the targeted [(tpy)NiBr] (1) was found to involve the comproportionation reaction of [(dme)NiBr{sub 2}] and [Ni(COD){sub 2}] in the presence of two equivalents of terpyridine. This reaction was driven to high yields of product formation (72 % isolated) by the precipitation of 1 from THF solvent.

    Project Abstract for “Steam Cycle Washer for Unbleached Pulp” When completed, the patented SC Washer will provide an innovative, energy efficient demonstration project to wash unbleached pulp using a pressure vessel charged with steam. The Port Townsend Paper Corporation’s pulp mill in Port Townsend, WA was initially selected as the host site for conducting the demonstration of the SCW. Due to 2006 and 2007 delays in the project caused by issues with 21st Century Pulp & Paper, the developer of the SCW, and the 2007 bankruptcy proceedings and subsequent restructuring at Port Townsend Paper, the mill can no longer serve as a host site. An alternate host site is now being sought to complete the commercial demonstration of the Steam Cycle Washer for Unbleached Pulp. Additionally, estimated costs to complete the project have more than doubled since the initial estimates for the project were completed in 2002. Additional grant funding from DOE was sought and in July, 2008 the additional DOE funds were procured under a new DOE award, DE-PS36-08GO98014 issued to INL. Once the new host site is secured the completion of the project will begin under the management of INL. Future progress reports and milestone tracking will be completed under requirements of new DOE Award Number DE-PS36-08GO98014. The following are excerpts from the project Peer Review completed in 2006. They describe the project in some detail. Additional information can be found by reviewing DOE Award Number: DE-PS36-08GO98014. 5. Statement of Problem and Technical Barriers: The chemical pulping industry is one of the major users of fresh water in the United States. On average the industry uses over 80 tons of water to produce one ton of pulp, some states use up to 50% more (Washington 120 and Wisconsin 140). In order to process one ton of pulp using 80 tons of process water, a large amount of: • energy is used in process heat and • power is required for pumping the large volume of pulp slurries

    The GreenRay Inc. program focused on simplifying solar electricity and making it affordable and accessible to the mainstream population. This was accomplished by integrating a solar module, micro-inverter, mounting and monitoring into a reliable, 'plug and play' AC system for residential rooftops, offering the following advantages: (1) Reduced Cost: Reduction in installation labor with fewer components, faster mounting, faster wiring. (2) Maximized Energy Production: Each AC Module operates at its maximum, reducing overall losses from shading, mismatch, or module downtime. (3) Increased Safety. Electrical and fire safety experts agree that AC Modules have significant benefits, with no energized wiring or live connections during installation, maintenance or emergency conditions. (4) Simplified PV for a Broader Group of Installers. Dramatic simplification of design and installation of a solar power system, enabling faster and more efficient delivery of the product into the market through well-established, mainstream channels. This makes solar more accessible to the public. (5) Broadened the Rooftop Market: AC Modules enable solar for many homes that have shading, split roofs, or obstructions. In addition, due to the smaller building block size of 200W vs. 1000W, homeowners with budget limitations can start small and add to their systems over time. Through this DOE program GreenRay developed the all-in-one AC Module system with an integrated PV Module and microinverter, custom residential mounting and performance monitoring. Development efforts took the product from its initial concept, through prototypes, to a commercial product sold and deployed in the residential market. This pilot deployment has demonstrated the technical effectiveness of the AC Module system in meeting the needs and solving the problems of the residential market. While more expensive than the traditional central inverter systems at the pilot scale, the economics of AC Modules become more and more

Density measurements were made with a multichannel CO{sub 2} (10.6 μm) laser interferometer. We also developed and a high-resolution magnetic probe array for 3-axis measurements of magnetic fluctuations. We constructed and implemented a triple Langmuir probe for making time-resolved measurements of plasma density, potential, and temperature. By calculating the time history of the gun eigenvalue, we observed indications that the Taylor formation paradigm applies. To estimate the spectral characteristics of fluctuations in an FRC, we developed a technique to extract the relevant spectral information using data from the high-resolution multi-point magnetic probe.

    Steve Winkelman; Tim Hargrave; Christine Vanderlan

    1999-10-01

    The authors conclude in this report that an upstream system would ensure complete regulatory coverage of transportation sector emissions in an efficient and feasible manner, and as such represents a key component of a national least-cost GHG emissions abatement strategy. The broad coverage provided by an upstream system recommends this approach over vehicle-maker based approaches, which would not cover emissions from heavy-duty vehicles and the aviation, marine and off-road sub-sectors. The on-road fleet approach unfairly and inefficiently burdens vehicle manufacturers with responsibility for emissions that they cannot control. A new vehicles approach would exclude emissions from vehicles on the road prior to program inception. The hybrid approach faces significant technical and political complications, and it is not clear that the approach would actually change behavior among vehicle makers and users, which is its main purpose. They also note that a trading system would fail to encourage many land use and infrastructure measures that affect VMT growth and GHG emissions. They recommend that this market failure be addressed by complementing the trading system with a program specifically targeting land use- and infrastructure-related activities. A key issue that must be addressed in designing a national GHG control strategy is whether or not it is necessary to guarantee GHG reductions from the transport sector. Neither an upstream system nor a downstream approach would do so, since both would direct capital to the least-cost abatement opportunities wherever they were found. They review two reasons why it may be desirable to force transportation sector reductions: first, that the long-term response to climate change will require reductions in all sectors; and second, the many ancillary benefits associated with transportation-related, and especially VMT-related, emissions reduction activities. If policy makers find it desirable to establish transportation

    The purpose of this project was to demonstrate the energy efficiency and reduced emissions that can be obtained with a dual torch DC plasma transferred arc-melting system. Plasmelt Glass Technologies, LLC was formed to solicit and execute the project, which utilize a full-scale test melter system. The system is similar to the one that was originally constructed by Johns Manville, but Plasmelt has added significant improvements to the torch design and melter system that has extended the original JM short torch lives. The original JM design has been shown to achieve melt rates 5 to 10 times faster than conventional gas or electric melting, with improved energy efficiency and reduced emissions. This project began on 7/28/2003 and ended 7/27/06. A laboratory scale melter was designed, constructed, and operated to conduct multiple experimental melting trials on various glass compositions. Glass quality was assessed. Although the melter design is generic and equally applicable to all sectors within the glass industry, the development of this melter has focused primarily on fiberglass with additional exploratory melting trials of frits, specialty, and minerals-melting applications. Throughput, energy efficiency, and glass quality have been shown to be heavily dependent on the selected glass composition. During this project, Plasmelt completed the proof-of-concept work in our Boulder, CO Lab to show the technical feasibility of this transferred-arc plasma melter. Late in the project, the work was focused on developing the processes and evaluating the economic viability of plasma melting aimed at the specific glasses of interest to specific client companies. Post project work is on going with client companies to address broader non-glass materials such as refractories and industrial minerals. Exploratory melting trials have been conducted on several glasses of commercial interest including: C-glass, E-glass, S-Glass, AR-Glass, B-glass, Lighting Glass, NE-Glass, and various

    The purpose of this project was to design, construct and test a simple, appropriate technology low pressure, high speed, wood-fired Stirling air engine of 100 W output. The final design was a concentric piston/displacer engine of 454 in. bore and 1 in. stroke with a rhombic drive mechanism. The project engine was ultimately completed and tested, using a propane burner for all tests as a matter of convenience. The 100 W aim was exceeded, at atmospheric pressure, over a wide range of engine speed with the maximum power being 112 W at 1150 rpm. A pressure can was constructed to permit pressurization; however the grant funds were running out, and the only pressurized power test attempted was unsuccessful due to seal difficulties. This was a disappointment because numerous tests on the 4 cubic inch engine suggested power would be more than doubled with pressurization at 25 psig. A manifold was designed and constructed to permit operation of the engine over a standard No. 40 pot bellied stove. The engine was run successfully, but at reduced speed and power, over this stove. The project engine started out being rather noisy in operation, but modifications ultimately resulted in a very quiet engine. Various other difficulties and their solutions also are discussed. (LCL)

    This is the Final Report for the Louisiana Industrial Assessment Center for the period of 9/1/2002 through 11/30/2006, although we were still gathering data through 02/16/2007. During this period, our Industrial Assessment Center completed 109 energy assessments for manufacturing firms in our area, offered 3 Save Energy Workshops, taught 26 students (9 graduate and 17 undergraduate) energy management savings techniques and offered an Energy Management Graduate class three times. These 109 energy assessments made a total of 738 energy savings recommendations, 33 waste reduction recommendations, and 108 productivity improvement recommendations. These combined recommendations would save client companies more than $87,741,221.16, annually at the then current energy costs. If all of these recommendations were implemented separately, the implementation cost would have been $34,113,482.10 or a Simple Payback Period, SPP=4.7 months. Between 9 months and 12 months after the assessment, we surveyed the manufacturing firms to find out what they implemented. They had implemented approximately 50 percent of our recommendations at an annual saving of $25,867,613.18. The three Save Energy Workshops had an average attendance of twelve individuals. The three graduate Energy Management courses had an average attendance of eleven students.

    This final report describes the results of a study of the potential energy savings associated with increased utilitarian bicycle transportation in the Denver metropolitan area. The project has included computer modeling of the carrying capacity of the present bicycle route system, future route systems, as well as outreach activities to convey the results to public officials and the general public. A key feature of the project has been a consideration of the benefits associated with an expanded bikeway system which includes ''bike boulevards''. Data from the west coast cities and other sources, have been used to generate quantitative estimates of the benefits associated with a Denver bikeway system which includes bike boulevards. The development of a network of bike boulevards in Denver should result in energy savings of about 20.2 million gallons of gasoline per year, as well as a 3.4% reduction in vehicular carbon monoxide emissions. These benefits are in addition to those accruing from current levels of bicycling.

The DGPL system provides a cost effective tool for repairing near well bore permeability damage caused by inappropriate chemical treatment, migrating fines and paraffins, or slotted liners blocked by sand. Because the gas is generated from a solid propellant material by chemical reaction, no heavy equipment is required. Tremendous pump rates can be obtained. Peak pressures are naturally localized at the tool position by the tamping effect of well fluids. Thus many of the leakage and sealing problems which plague static hydrofrac processes ore completely avoided. DGPL may be effectively used before acid treatment to provide fresh pathways for the acid to reach the formation. The smaller tools may be positioned by wireline, though most Stressfrac tools are tubing conveyed.

    This project was funded to Dr. Mary Neu (LANL) and to Dr. Patricia Holden (UCSB) during the period 10/01/04-09/30/07 with the overall objective of, as stated in the proposal, to investigate how key reactions, which are known to affect major redox-active transition metals such as Fe and Mn, can affect Pu speciation and environmental mobility. The goals included investigating a) bacterial accumulation and immobilization of Pu species by Pseudomonas putida biofilm formation, and b) bacterial mineralization and immobilization via direct enzymatic and indirect biogeochemical reduction of Pu species by Geobacter metallireducens. Through a combination of aqueous chemical, radioanalytical, spectroscopic and microscopic analyses, Pu speciation and solution/solid phase distributions were to be characterized. The combination of biotransformation and biogeochemical research was aimed at filling significant gaps in the scientific basis for monitored natural attenuation and in situ stabilization of widespread and problematic Pu contamination, as well as providing immediately useful data to modeling and risk assessment efforts.

    position in developing quality and competency standards for solar professionals and for training programs critical components to bring the solar industry into step with other recognized craft labor forces. IREC's objective was to provide consumer assurances and assist the states and the solar industry in building a strong and qualified workforce. IREC's Schools Going Solar Clearinghouse provided channels of information to educate students, teachers, parents and the community at large about the benefits of solar energy. Solar school projects enhance science and math education while creating an initial entry market for domestic PV. And, IREC's community and outreach network got the right information out to capture the interest and met the needs of different audiences and reached groups that weren't traditionally part of the solar community. IREC's PV4You project was effective because it resulted in reduced costs through easier interconnection and better net metering agreements and by raising the competency standards for solar practitioners. The project provided ways to eliminate barriers and constraints by providing technical assistance, offering model agreements based on industry consensus that were used by state and local decision makers. And, the project increased public acceptance by providing information, news and guidelines for different audiences.

  16. Verification of Steelmaking Slags Iron Content Final Technical Progress Report

    2006-10-04

    The steel industry in the United States generates about 30 million tons of by-products each year, including 6 million tons of desulfurization and BOF/BOP slag. The recycling of BF (blast furnace) slag has made significant progress in past years with much of the material being utilized as construction aggregate and in cementitious applications. However, the recycling of desulfurization and BOF/BOP slags still faces many technical, economic, and environmental challenges. Previous efforts have focused on in-plant recycling of the by-products, achieving only limited success. As a result, large amounts of by-products of various qualities have been stockpiled at steel mills or disposed into landfills. After more than 50 years of stockpiling and landfilling, available mill site space has diminished and environmental constraints have increased. The prospect of conventionally landfilling of the material is a high cost option, a waste of true national resources, and an eternal material liability issue. The research effort has demonstrated that major inroads have been made in establishing the viability of recycling and reuse of the steelmaking slags. The research identified key components in the slags, developed technologies to separate the iron units and produce marketable products from the separation processes. Three products are generated from the technology developed in this research, including a high grade iron product containing about 90%Fe, a medium grade iron product containing about 60% Fe, and a low grade iron product containing less than 10% Fe. The high grade iron product contains primarily metallic iron and can be marketed as a replacement of pig iron or DRI (Direct Reduced Iron) for steel mills. The medium grade iron product contains both iron oxide and metallic iron and can be utilized as a substitute for the iron ore in the blast furnace. The low grade iron product is rich in calcium, magnesium and iron oxides and silicates. It has a sufficient lime value and

    The development of approaches to harness marine and hydrokinetic energy at large-scale is predicated on the compatibility of these generation technologies with the marine environment. At present, aspects of this compatibility are uncertain. Demonstration projects provide an opportunity to address these uncertainties in a way that moves the entire industry forward. However, the monitoring capabilities to realize these advances are often under-developed in comparison to the marine and hydrokinetic energy technologies being studied. Public Utility District No. 1 of Snohomish County has proposed to deploy two 6-meter diameter tidal turbines manufactured by OpenHydro in northern Admiralty Inlet, Puget Sound, Washington. The goal of this deployment is to provide information about the environmental, technical, and economic performance of such turbines that can advance the development of larger-scale tidal energy projects, both in the United States and internationally. The objective of this particular project was to develop environmental monitoring plans in collaboration with resource agencies, while simultaneously advancing the capabilities of monitoring technologies to the point that they could be realistically implemented as part of these plans. In this, the District was joined by researchers at the Northwest National Marine Renewable Energy Center at the University of Washington, Sea Mammal Research Unit, LLC, H.T. Harvey & Associates, and Pacific Northwest National Laboratory. Over a two year period, the project team successfully developed four environmental monitoring and mitigation plans that were adopted as a condition of the operating license for the demonstration project that issued by the Federal Energy Regulatory Commission in March 2014. These plans address nearturbine interactions with marine animals, the sound produced by the turbines, marine mammal behavioral changes associated with the turbines, and changes to benthic habitat associated with colonization

    The purpose of this study was to explore the possibility of control of product selectivity in the hydroprocessing of coal liquids and related substances by adding small amounts of ammonia. Quinoline was used in this study and in many others as representative of heterocyclic N compounds found in coal liquids. Coal liquids also contain hydroxy pyridines, but by studies with 8-OH quinoline, a representative compound (Part I), we demonstrated that the OH group was rapidly removed at the beginning of reaction to form quinoline, which reacted in the same manner as quinoline fed as such. In Part II we showed that in a mixture of naphthalene and quinoline, with the addition of ammonia there is an operating region in which complete HDN of quinoline can be achieved, but with greater conversion of naphthalene to tetralin instead of to decalin than was the case in the absence of added ammonia. This is of some significance to coal liquefaction since tetralin is a good hydrogen donor, but decalin is not. In Part III we showed that NH{sub 3} addition to a mixture of quinoline and phenanthrene provides an operating region where complete HDN of quinoline can be achieved with reduced formation of hydrogenated phenanthrenes and cracking to biphenyl. Part IV, a study of the hydrodeoxygenation (DHO) of dibenzofuran in the presence of naphthalene, showed that NH{sub 3} strongly inhibits HDO reactions and its effects on naphthalene here were much the same as in Part II. In Part V it was demonstrated that in the hydrotreating of propylbenzene, the addition of ammonia increased the selectivity towards ring hydrogenation (generally desired for reformulated motor fuels) and away from dealkylation (generally undesired), but the overall reaction rate at a fixed temperature drops substantially.

    Final technical report for Conjugated ionomers for photovoltaic applications, electric field driven charge separation in organic photovoltaics. The central goal of the work we completed was been to understand the photochemical and photovoltaic properties of ionically functionalized conjugated polymers (conjugated ionomers or polyelectrolytes) and energy conversion systems based on them. We primarily studied two classes of conjugated polymer interfaces that we developed based either upon undoped conjugated polymers with an asymmetry in ionic composition (the ionic junction) or doped conjugated polymers with an asymmetry in doping type (the p-n junction). The materials used for these studies have primarily been the polyacetylene ionomers. We completed a detailed study of p-n junctions with systematically varying dopant density, photochemical creation of doped junctions, and experimental and theoretical work on charge transport and injection in polyacetylene ionomers. We have also completed related work on the use of conjugated ionomers as interlayers that improve the efficiency or organic photovoltaic systems and studied several important aspects of the chemistry of ionically functionalized semiconductors, including mechanisms of so-called "anion-doping", the formation of charge transfer complexes with oxygen, and the synthesis of new polyfluorene polyelectrolytes. We also worked worked with the Haley group at the University of Oregon on new indenofluorene-based organic acceptors.

    Ocean Thermal Energy Conversion can exploit natural temperature gradients in the oceans to generate usable forms of energy (for example, cost-competitive baseload electricity in tropical regions such as Hawaii) free from fossil fuel consumption and global warming emissions.The No.1 acknowledged challenge of constructing an OTEC plant is the Cold Water Pipe (CWP), which draws cold water from 1000m depths up to the surface, to serve as the coolant for the OTEC Rankine cycle. For a commercial-scale plant, the CWP is on the order of 10m in diameter.This report describes work done by LMSSC developing the CWP for LM MS2 New Ventures emerging OTEC business. The work started in early 2008 deciding on the minimum-cost CWP architecture, materials, and fabrication process. In order to eliminate what in previous OTEC work had been a very large assembly/deployment risk, we took the innovative approach of building an integral CWP directly from theOTEC platform and down into the water. During the latter half of 2008, we proceeded to a successful small-scale Proof-of-Principles validation of the new fabrication process, at the Engineering Development Lab in Sunnyvale. During 2009-10, under the Cooperative Agreement with the US Dept. of Energy, we have now successfully validated key elements of the process and apparatus at a 4m diameter scale suitable for a future OTEC Pilot Plant. The validations include: (1) Assembly of sandwich core rings from pre-pultruded hollow 'planks,' holding final dimensions accurately; (2) Machine-based dispensing of overlapping strips of thick fiberglass fabric to form the lengthwise-continuous face sheets, holding accurate overlap dimensions; (3) Initial testing of the fabric architecture, showing that the overlap splices develop adequate mechanical strength (work done under a parallel US Naval Facilities Command program); and (4) Successful resin infusion/cure of 4m diameter workpieces, obtaining full wet-out and a non-discernable knitline between

    The objective of this project is to gain a comprehensive understanding of the key atmospheric mechanisms and physical processes associated with temperature extremes in order to better interpret and constrain uncertainty in climate model simulations of future extreme temperatures. To achieve this objective, we first used climate observations and a reanalysis product to identify the key atmospheric circulation patterns associated with extreme temperature days over North America during the late twentieth century. We found that temperature extremes were associated with distinctive signatures in near-surface and mid-tropospheric circulation. The orientations and spatial scales of these circulation anomalies vary with latitude, season, and proximity to important geographic features such as mountains and coastlines. We next examined the associations between daily and monthly temperature extremes and large-scale, recurrent modes of climate variability, including the Pacific-North American (PNA) pattern, the northern annular mode (NAM), and the El Niño-Southern Oscillation (ENSO). The strength of the associations are strongest with the PNA and NAM and weaker for ENSO, and also depend upon season, time scale, and location. The associations are stronger in winter than summer, stronger for monthly than daily extremes, and stronger in the vicinity of the centers of action of the PNA and NAM patterns. In the final stage of this project, we compared climate model simulations of the circulation patterns associated with extreme temperature days over North America with those obtained from observations. Using a variety of metrics and self-organizing maps, we found the multi-model ensemble and the majority of individual models from phase 5 of the Coupled Model Intercomparison Project (CMIP5) generally capture the observed patterns well, including their strength and as well as variations with latitude and season. The results from this project indicate that current models are capable

  4. Final Technical Report - In-line Uranium Immunosensor

    Blake, Diane A.

    2006-07-05

    In this project, personnel at Tulane University and Sapidyne Instruments Inc. developed an in-line uranium immunosensor that could be used to determine the efficacy of specific in situ biostimulation approaches. This sensor was designed to operate autonomously over relatively long periods of time (2-10 days) and was able to provide near real-time data about uranium immobilization in the absence of personnel at the site of the biostimulation experiments. An alpha prototype of the in-line immmunosensor was delivered from Sapidyne Instruments to Tulane University in December of 2002 and a beta prototype was delivered in November of 2003. The beta prototype of this instrument (now available commercially from Sapidyne Instruments) was programmed to autonomously dilute standard uranium to final concentrations of 2.5 to 100 nM (0.6 to 24 ppb) in buffer containing a fluorescently labeled anti-uranium antibody and the uranium chelator, 2,9-dicarboxyl-1,10-phenanthroline. The assay limit of detection for hexavalent uranium was 5.8 nM or 1.38 ppb. This limit of detection is well below the drinking water standard of 30 ppb recently promulgated by the EPA. The assay showed excellent precision; the coefficients of variation (CV’s) in the linear range of the assay were less than 5% and CV’s never rose above 14%. Analytical recovery in the immunosensors-based assay was assessed by adding variable known quantities of uranium to purified water samples. A quantitative recovery (93.75% - 108.17%) was obtained for sample with concentrations from 7.5 to 20 nM (2-4.75 ppb). In August of 2005 the sensor was transported to Oak Ridge National Laboratory, for testing of water samples at the Criddle test site (see Wu et al., Environ. Sci. Technol. 40:3978-3985 2006 for a description of this site). In this first on-site test, the in-line sensor was able to accurately detect changes in the concentrations of uranium in effluent samples from this site. Although the absolute values for the

    Efforts to fabricate and study a new photovoltaic material, copper indium boron diselenide (CuInxB1-xSe2 or CIBS), were undertaken. Attempts to prepare CIBS using sputtering deposition techniques resulted in segregation of boron from the rest of elements in the material. CIBS nanocrystals were prepared from the reaction of elemental Se with CuCl, InCl3, and boric acid in solution, but the product material quickly decomposed upon heating that was required in attempts to convert the nanocrystals into a thin film. The investigation of the reasons for the lack of CIBS material stability led to new structure-property studies of closely-related photovoltaic systems as well as studies of new solar cell materials and processing methods that could enhance the development of next-generation solar technologies. A detailed compositional study of CuIn1-xAlxSe2 (CIAS, a system closely related to CIBS) revealed a non-linear correlation between crystal lattice size and the Al/(In+Al) ratios with dual-phase formation being observed. A new nanocrystal-to-thin-film processing method was developed for the preparation of CuIn1-xGaxSe2 (CIGS) thin films in which colloidal Se particles are sprayed in contact with CuIn1-xGaxS2 nanoparticles and heated in an argon atmosphere with no other Se source in the system. The process is non-vacuum and does not require toxic gases such as Se vapor or H2Se. Expertise gained from these studies was applied to new research in the preparation of thin-film pyrite FeS2, an attractive earth-abundant candidate material for next-generation photovoltaics. Three methods successfully produced pure pyrite FeS2 films: sulfurization of sputtered Fe films, chemical bath deposition, and sulfurization of Fe2O3 sol-gel precursors. The last method produced pinhole-free films that may be viable for device development. Nickel, platinum, and possibly carbon would appear to serve as good ohmic contact materials. While CdS has a reasonable conduction band energy match to

    The purpose of this report was to provide, at BPA's request, a technical review of interim products received for Project 2001-015-00 under contract 6925. BPA sometimes solicits technical reviews for Fish and Wildlife products or issues where outside expertise is required. External review of complex project deliverables assures BPA as a funding agency that the contractor is continuing with scientifically-credible experimental techniques envisioned in the original proposal. If the project's methodology proves feasible, there could be potential applications beyond the project area to similar situations in the Columbia Basin. The Experiment involves artificial flooding during high flow periods and a determination of the portion of the return flows that end up in the Umatilla River during low flow months and within acceptable water quality parameters (e.g., low temperature, few contaminants). Flooding could be a critical water source for aquatic organisms at times of the year when flows in the lower reaches of the Umatilla River are low and water is warmer than would be desired. The experiment was proposed to test whether 'this process, recharges the shallow aquifers of the old flood plain, for natural filtration through the alluvial soils as it returns to the Umatilla River, cleaner and cooler (about 50 degree Fahrenheit) five to six month later (about July and August) substantially cooling the river and [making it] more beneficial to anadromous [fish]'. A substantial amount of preliminary data had been collected and preliminary results were submitted in an interim report 'Echo Meadows Project Winter Artificial Recharge: Final Report for 2001 Baseline (December 2002)'. A substantial amount of addition funding was provided for the last cycle of flooding (Phases II) and final analyses of the full compliment of data collected over the life of the contract (Phase III).

    2012-10-31

    The Cellulosic Based Black Liquor Gasification and Fuels Plant Project was developed to construct a black liquor to Methanol biorefinery in Escanaba, Michigan. The biorefinery was to be co-located at the existing pulp and paper mill, NewPage’s Escanaba Paper Mill and when in full operation would: • Generate renewable energy for Escanaba Paper Mill • Produce Methanol for transportation fuel of further refinement to Dimethyl Ether • Convert black liquor to white liquor for pulping. Black liquor is a byproduct of the pulping process and as such is generated from abundant and renewable lignocellulosic biomass. The biorefinery would serve to validate the thermochemical pathway and economic models for black liquor gasification. It was a project goal to create a compelling new business model for the pulp and paper industry, and support the nation’s goal for increasing renewable fuels production and reducing its dependence on foreign oil. NewPage Corporation planned to replicate this facility at other NewPage Corporation mills after this first demonstration scale plant was operational and had proven technical and economic feasibility. An overview of the process begins with black liquor being generated in a traditional Kraft pulping process. The black liquor would then be gasified to produce synthesis gas, sodium carbonate and hydrogen sulfide. The synthesis gas is then cleaned with hydrogen sulfide and carbon dioxide removed, and fed into a Methanol reactor where the liquid product is made. The hydrogen sulfide is converted into polysulfide for use in the Kraft pulping process. Polysulfide is a known additive to the Kraft process that increases pulp yield. The sodium carbonate salts are converted to caustic soda in a traditional recausticizing process. The caustic soda is then part of the white liquor that is used in the Kraft pulping process. Cellulosic Based Black Liquor Gasification and Fuels Plant project set out to prove that black liquor gasification could

    The Final Waste Forms (FWF) Technical Area Status Report (TASR) Working Group, the Vitrification Working Group (WG), and the Performance Standards Working Group were established as subgroups to the FWF Technical Support Group (TSG). The FWF TASR WG is comprised of technical representatives from most of the major DOE sites, the Nuclear Regulatory Commission (NRC), the EPA Office of Solid Waste, and the EPA`s Risk Reduction Engineering Laboratory (RREL). The primary activity of the FWF TASR Working Group was to investigate and report on the current status of FWFs for LLNM in this TASR. The FWF TASR Working Group determined the current status of the development of various waste forms described above by reviewing selected articles and technical reports, summarizing data, and establishing an initial set of FWF characteristics to be used in evaluating candidate FWFS; these characteristics are summarized in Section 2. After an initial review of available information, the FWF TASR Working Group chose to study the following groups of final waste forms: hydraulic cement, sulfur polymer cement, glass, ceramic, and organic binders. The organic binders included polyethylene, bitumen, vinyl ester styrene, epoxy, and urea formaldehyde. Section 3 provides a description of each final waste form. Based on the literature review, the gaps and deficiencies in information were summarized, and conclusions and recommendations were established. The information and data presented in this TASR are intended to assist the FWF Production and Assessment TSG in evaluating the Technical Task Plans (TTPs) submitted to DOE EM-50, and thus provide DOE with the necessary information for their FWF decision-making process. This FWF TASR will also assist the DOE and the MWIP in establishing the most acceptable final waste forms for the various LLMW streams stored at DOE facilities.

    The remedial strategy for addressing contaminated environmental media was recently finalized for the US Department of Energy`s (DOE) Fernald Environmental Management Project (FEMP) following almost 10 years of detailed technical analysis. The FEMP represents one of the first major nuclear facilities to successfully complete the Remedial Investigation/Feasibility Study (RI/FS) phase of the environmental restoration process. A critical element of this success was the establishment of sensible cleanup levels for contaminated soil and groundwater both on and off the FEMP property. These cleanup levels were derived based upon a strict application of Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) regulations and guidance, coupled with positive input from the regulatory agencies and the local community regarding projected future land uses for the site. The approach for establishing the cleanup levels was based upon a Feasibility Study (FS) strategy that examined a bounding range of viable future land uses for the site. Within each land use, the cost and technical implications of a range of health-protective cleanup levels for the environmental media were analyzed. Technical considerations in driving these cleanup levels included: direct exposure routes to viable human receptors; cross- media impacts to air, surface water, and groundwater; technical practicality of attaining the levels; volume of affected media; impact to sensitive environmental receptors or ecosystems; and cost. This paper will discuss the technical approach used to support the finalization of the cleanup levels for the site. The final cleanup levels provide the last remaining significant piece to the puzzle of establishing a final site-wide remedial strategy for the FEMP, and positions the facility for the expedient completion of site-wide remedial activities.

    2009-05-04

    This project focused on studying trace gases that participate in chemical reactions that form atmospheric aerosols. Ammonium sulfate is a major constituent of these tiny particles, and one important pathway to sulfate formation is oxidation of dissolved sulfur dioxide by hydrogen peroxide in cloud, fog and rainwater. Sulfate aerosols influence the number and size of cloud droplets, and since these factors determine cloud radiative properties, sulfate aerosols also influence climate. Peroxide measurements, in conjunction with those of other gaseous species, can used to distinguish the contribution of in-cloud reaction to new sulfate aerosol formation from gas-phase nucleation reactions. This will lead to more reliable global climate models. We constructed and tested a new 4-channel fluorescence detector for airborne detection of peroxides. We integrated the instrument on the G-1 in January, 2006 and took a test flight in anticipation of the MAX-Mex field program, where we planned to fly under pressurized conditions for the first time. We participated in the 2006 Megacity Initiative: Local and Global Research Observations (MILAGRO) - Megacity Aerosol EXperiment Mexico City (MAX-Mex) field measurement campaign. Peroxide instrumentation was deployed on the DOE G-1 research aircraft based in Veracruz, and at the surface site at Tecamac University.

    1996-07-01

    The primary objective of this project was to perform the optics and materials research necessary to identify and solve the technical problems associated with fabricating durable, variable reflectivity electrochromic windows for energy efficient buildings and vehicles. The research performed at the Tufts Electro-Optics Technology Center (EOTC) has identified and solved nearly all the significant problems, as discussed below in this final technical report. There still remains, however, one important problem to be solved--i.e., to better understand the science of deposition processes and thereby develop and optimize one or more production-worthy deposition processes that could be used for the practical production of affordable, variable reflectivity electrochromic windows. Therefore, it is recommended that such studies be carried out with the goals of: (1) determining the probable practical limits of performance; and, very importantly, (2) to develop and optimize deposition processes that could be used for the practical production of affordable electrochromic windows.

    Final technical report summarizes the program progress and technical accomplishments of the Laser Direct Manufacturing (LDM) for Nuclear Power Components project. A series of experiments varying build process parameters (scan speed and laser power) were conducted at the outset to establish the optimal build conditions for each of the alloys. Fabrication was completed in collaboration with Quad City Manufacturing Laboratory (QCML). The density of all sample specimens was measured and compared to literature values. Optimal build process conditions giving fabricated part densities close to literature values were chosen for making mechanical test coupons. Test coupons whose principal axis is on the x-y plane (perpendicular to build direction) and on the z plane (parallel to build direction) were built and tested as part of the experimental build matrix to understand the impact of the anisotropic nature of the process.. Investigations are described 316L SS, Inconel 600, 718 and 800 and oxide dispersion strengthed 316L SS (Yttria) alloys.

    Seinfeld, J.H.; Flagan, R.C.

    1994-04-04

    Aerosol formation from the photooxidation of A-pinene/NOx and B-pinene/NOx mixtures has been investigated in a series of outdoor smog chamber experiments. Both hydrocarbons are potent aerosol formers and in areas containing significant vegetation, terpenes are estimated to be a significant contributor to secondary organic aerosol formation. To model organic aerosol formation, estimates of the vapor pressures of the condensable species are needed. To measure the vapor pressures of the low volatility species characteristic of organic aerosols the Tandem Differential Mobility Analyzer (TDMA) method introduced by Liu and McMurray has been further developed for this task. Initial experiments with compounds of known vapor pressure confirm the usefulness of the method.

    1983-05-01

    The formation of nitrosamines under denitrification conditions was evaluated as part of the Army's program on pollution abatement. Various amines (dimethyl-diethanol-, dipropyl- and dibutyl-) were evaluated in batch and/or continuous culture microbial systems under anaerobic conditions with high nitrate loads. With the exception of dimethylamine, tha amines do not form detectable concentrations of the corresponding nitrosamines in the alkaline denitrificatioin systems. N-nitrosodimethylamine (NDMA) is detected in part per billion concentrations in many of these systems. The formation of NDMA is apparently not biologically mediated in the batch systems, however, the reason for its formation in the continuous systems is not clear. The contribution of microbially produced catalysts and the role of the intracellular environment in the reactions is discussed.

    1982-01-01

    A survey was conducted to determine the opinions of readers concerning the format (organization) of NASA technical reports and usage of technical report components. A survey questionnaire was sent to 513 LaRC engineers and scientists and 600 engineers and scientists from three (3) professional/technical societies. The response rates were 74 and 85 percent, respectively. The questionnaire included the order in which users read report components, the components reviewed or read to determine whether to read a report, report components which could be deleted, the desirability of a table of contents, the desirability of both a summary and abstract, the location of the symbols list and glossary, the integration of illustrative material, the preferred format for reference citations, column layout and right margin treatment, and person/voice. The results of the reader preference survey indicated that the conclusion was the component most often ready by survey respondents. The summary, conclusion, abstract, title page, and introduction were the components used most frequently to determine if a report would actually be read. Respondents indicated that a summary as well as an abstract should be included, that the definition of symbols and glossary of terms should be located in the front of the report, and that illustrative material should be integrated with the text rather than grouped at the end of the report. Citation by number was the preferred format for references. A one-column, ragged right margin was preferred. Third person, passive voice was the style of writing preferred by the respondents.

  2. CO/sub 2/ formation damage study. Final report

    SciTech Connect

    Patton, J.T.

    1983-07-01

    The literature did provide insight into four possible damage mechanisms, namely: (1) precipitation of reservoir mineral in the vicinity around the producing well as carbon dioxide escapes from the water phase due to pressure draw down; (2) plugging of reservoir interstices by insoluble organic solids precipitated as the carbon dioxide dissolves in crude oil; (3) formation of an immobile gas phase, predominately CO/sub 2/, which would drastically lower the effective permeability to oil and, especially water; and (4) dissolution of cementation, especially carbonates or feldspars, that could allow fines to migrate in the reservoir and plug tiny flow passages. Each of these mechanisms was investigated in depth during the laboratory experiments. Occasional reports from industry suggested that the use of carbon dioxide to enhance the recovery of tertiary oil might be causing formation damage. This project was undertaken to define the mechanisms responsible for such occurrences. The objectives were threefold: (1) provide a comprehensive literature survey to elicit all that is currently known or suspected, relative to formation damage that might occur during the injection of carbon dioxide into an oil reservoir; (2) under simulated reservoir conditions, demonstrate in the laboratory each of the damage mechanisms and quantify the degree to which each mechanism could cause damage; and (3) for those damage mechanisms identified to be significant, develop a feasible remedy, easily applied in actual field operations. The third mechanism, related to the presence of an immobile gas phase, is a real problem but not unique to the injection of carbon dioxide. In the case of carbon dioxide, the damage should be self-correcting, as the solubility of carbon dioxide in water will eventually allow the water to dissolve away the gas and, hence, the blocking effect.

  3. DOE final report: Studies on the microbial formation of methane

    SciTech Connect

    Wolfe, Ralph S.

    2001-04-01

    The microbial formation of methane is carried out by methanogens which are found wherever active anaerobic degradation of organic matter occurs. We developed a procedure for reliable culture of 'Methanococus jannaschii' which yields 8 g wet weight of cells per liter of medium. To initiate a study of proteomics, this organism was grown at two levels of hydrogen partial pressure, very low (650 Pa) and high (178 kPa). When cells were exposed to hydrogen excess conditions, they possessed very low or undetectable levels of four flagella-related polypeptides, whereas, when hydrogen became limiting, these proteins were synthesized. Thus, use of proteomics showed, for the first time, that this methanogen can regulate expression of proteins, and these experiments open the door for general studies of regulation in this hyperthermophile.

    2015-10-02

    This is the final technical report for DOE Grant #DE-FG02-04ER54795-Experimental Investigations of Fundamental Processes in Dusty Plasmas. A plasma is an ionized gas, and a dusty plasmas is a plasma that contains, in addition to electrons and ions, micron-sized dust particles. The dust particles acquire and electric charge in the plasma by collecting electrons and ions. The electrons move more rapidly than the ions, so the dust charge is negative. A 1 micron dust particle in a typical low temperature plasma has a charge corresponding to approximately 2000 electrons. Dusty plasmas are naturally found in astrophysical plasmas, planetary rings, technological plasmas, and magnetic fusion plasmas. The goal of this project was to study in the laboratory, the basic physical processes that occur in dusty plasmas. This report provides a summary of the major scientific products and activities of this award.

    1992-05-15

    The formation and retention of methane in coalbeds was studied for ten Utah coal samples, one Colorado coal sample and eight coal samples from the Argonne Premium Coal Sample Bank.Methane gas content of the Utah and Colorado coals varied from zero to 9 cm{sup 3}/g. The Utah coals were all high volatile bituminous coals. The Colorado coal was a gassy medium volatile bituminous coal. The Argonne coals cover a range or rank from lignite to low volatile bituminous coal and were used to determine the effect of rank in laboratory studies. The methane content of six selected Utah coal seams and the Colorado coal seam was measured in situ using a special sample collection device and a bubble desorbometer. Coal samples were collected at each measurement site for laboratory analysis. The cleat and joint system was evaluated for the coal and surrounding rocks and geological conditions were noted. Permeability measurements were performed on selected samples and all samples were analyzed for proximate and ultimate analysis, petrographic analysis, {sup 13}C NMR dipolar-dephasing spectroscopy, and density analysis. The observed methane adsorption behavior was correlated with the chemical structure and physical properties of the coals.

    The objectives of the project were to understand the oil production mechanisms in the Monument Butte unit via reservoir characterization and reservoir simulations and to transfer the water flooding technology to similar units in the vicinity, particularly the Travis and the Boundary units. The reservoir characterization activity in the project basically consisted of extraction and analysis of a full diameter core, Formation Micro Imaging (FMI) logs from several wells and Magnetic Resonance Imaging (MRI) logs from two wells. In addition, several side-wall cores were drilled and analyzed, oil samples from a number of wells were physically and chemically characterized (using high-temperature gas chromatography), oil-water relative permeabilities were measured and pour points and cloud points of a few oil samples were determined. The reservoir modeling activity comprised of reservoir simulation of all the three units at different scales and near well-bore modeling of the wax precipitation effects. The reservoir simulation activities established the extent of pressurization of the sections of the reservoirs in the immediate vicinity of the Monument Butte unit. This resulted in a major expansion of the unit and the production from this expanded unit increased from about 300 barrels per day to about 2,000 barrels per day.

    The objective of this project is to provide detailed information on methods of minimizing soot formation during synthetic liquid fuel combustion under conditions which minimize fuel nitrogen conversion to nitric oxide. The program consists of two tasks. The purpose of the first task, Fuel Screening Studies, is to investigate the impact of fuel properties on particulate production, to establish the importance of droplet size and examine atomizer effects, and to develop techniques for surrogate fuels productions. In the second task, Flame Studies, the fundamental details of soot formation from synfuel droplet combustion will be investigated in variable slip velocity configurations. This present report describes technical progress during the first three months of the program effort (October-December 1980). During this initial period, attention has focused on the definition of the different experimental efforts and on the design and construction of the required hardware. Aspects of this work are discussed.

    The research supported by this award pursued three lines of inquiry: (1) The construction of dynamic general equilibrium models to simulate the accumulation and substitution of knowledge, which has resulted in the preparation and submission of several papers: (a) A submitted pedagogic paper which clarifies the structure and operation of computable general equilibrium (CGE) models (C.2), and a review article in press which develops a taxonomy for understanding the representation of technical change in economic and engineering models for climate policy analysis (B.3). (b) A paper which models knowledge directly as a homogeneous factor, and demonstrates that inter-sectoral reallocation of knowledge is the key margin of adjustment which enables induced technical change to lower the costs of climate policy (C.1). (c) An empirical paper which estimates the contribution of embodied knowledge to aggregate energy intensity in the U.S. (C.3), followed by a companion article which embeds these results within a CGE model to understand the degree to which autonomous energy efficiency improvement (AEEI) is attributable to technical change as opposed to sub-sectoral shifts in industrial composition (C.4) (d) Finally, ongoing theoretical work to characterize the precursors and implications of the response of innovation to emission limits (E.2).

  16. System-Cost-Optimized Smart EVSE for Residential Application: Final Technical Report including Manufacturing Plan

    SciTech Connect

    Zhu, Charles

    2015-05-15

    In the 2nd quarter of 2012, a program was formally initiated at Delta Products to develop smart-grid-enabled Electric Vehicle Supply Equipment (EVSE) product for residential use. The project was funded in part by the U.S. Department of Energy (DOE), under award DE-OE0000590. Delta products was the prime contractor to DOE during the three year duration of the project. In addition to Delta Products, several additional supplier-partners were engaged in this research and development (R&D) program, including Detroit Edison DTE, Mercedes Benz Research and Development North America, and kVA. This report summarizes the program and describes the key research outcomes of the program. A technical history of the project activities is provided, which describes the key steps taken in the research and the findings made at successive stages in the multi-stage work. The evolution of an EVSE prototype system is described in detail, culminating in prototypes shipped to Department of Energy Laboratories for final qualification. After the program history is reviewed, the key attributes of the resulting EVSE are described in terms of functionality, performance, and cost. The results clearly demonstrate the ability of this EVSE to meet or exceed DOE's targets for this program, including: construction of a working product-intent prototype of a smart-grid-enabled EVSE, with suitable connectivity to grid management and home-energy management systems, revenue-grade metering, and related technical functions; and cost reduction of 50% or more compared to typical market priced EVSEs at the time of DOE's funding opportunity announcement (FOA), which was released in mid 2011. In addition to meeting all the program goals, the program was completed within the original budget and timeline established at the time of the award. The summary program budget and timeline, comparing plan versus actual values, is provided for reference, along with several supporting explanatory notes. Technical information

  17. Semiconductor electrochemistry of coal pyrite. Final technical report, September 1990--September 1995

    Osseo-Asare, K.; Wei, Dawei

    1996-01-01

    This project seeks to advance the fundamental understanding of the physico-chemical processes occurring at the pyrite/aqueous interface, in the context of coal cleaning, coal desulfurization, and acid mine drainage. Central to this research is the use of synthetic microsize particles of pyrite as model microelectrodes to investigate the semiconductor electrochemistry of pyrite. The research focuses on: (a) the synthesis of microsize particles of pyrite in aqueous solution at room temperature, (b) the formation of iron sulfide complex, the precursor of FeS or FeS{sub 2}, and (c) the relationship between the semiconductor properties of pyrite and its interfacial electrochemical behavior in the dissolution process. In Chapter 2, 3 and 4, a suitable protocol for preparing microsize particles of pyrite in aqueous solution is given, and the essential roles of the precursors elemental sulfur and ``FeS`` in pyrite formation are investigated. In Chapter 5, the formation of iron sulfide complex prior to the precipitation of FeS or FeS{sub 2} is investigated using a fast kinetics technique based on a stopped-flow spectrophotometer. The stoichiometry of the iron sulfide complex is determined, and the rate and formation constants are also evaluated. Chapter 6 provides a summary of the semiconductor properties of pyrite relevant to the present study. In Chapters 7 and 8, the effects of the semiconductor properties on pyrite dissolution are investigated experimentally and the mechanism of pyrite dissolution in acidic aqueous solution is examined. Finally, a summary of the conclusions from this study and suggestions for future research are presented in Chapter 9.

    Balkwill, David L.

    2002-08-17

    This final technical report describes the research carried out during the final two months of the no-cost extension ending 11/14/01. The primary goals of the project were (1) to determine the potential for transformation of Cr(VI) (oxidized, mobile) to Cr(III) (reduced, immobile) under unsaturated conditions as a function of different levels and combinations of (a) chromium, (b) nitrate (co-disposed with Cr), and (c) molasses (inexpensive bioremediation substrate), and (2) to determine population structure and activity in experimental treatments by characterization of the microbial community by signature biomarker analysis and by RT-PCR and terminal restriction fragment length polymorphism (T-RFLP) and 16S ribosomal RNA genes. It was determined early in the one-year no-cost extension period that the T-RFLP approach was problematic in regard to providing information on the identities of microorganisms in the samples examined. As a result, it could not provide the detailed information on microbial community structure that was needed to assess the effects of treatments with chromium, nitrate, and/or molasses. Therefore, we decided to obtain the desired information by amplifying (using TR-PCR, with the same primers used for T-RFLP) and cloning 16S rRNA gene sequences from the same RNA extracts that were used for T-RFLP analysis. We also decided to use a restriction enzyme digest procedure (fingerprinting procedure) to place the clones into types. The primary focus of the research carried out during this report period was twofold: (a) to complete the sequencing of the clones, and (b) to analyze the clone sequences phylogenetically in order to determine the relatedness of the bacteria detected in the samples to each other and to previously described genera and species.

  14. A configuration space toolkit for automated spatial reasoning: Technical results and LDRD project final report

    SciTech Connect

    Xavier, P.G.; LaFarge, R.A.

    1997-02-01

    A robot`s configuration space (c-space) is the space of its kinematic degrees of freedom, e.g., the joint-space of an arm. Sets in c-space can be defined that characterize a variety of spatial relationships, such as contact between the robot and its environment. C-space techniques have been fundamental to research progress in areas such as motion planning and physically-based reasoning. However, practical progress has been slowed by the difficulty of implementing the c-space abstraction inside each application. For this reason, we proposed a Configuration Space Toolkit of high-performance algorithms and data structures meeting these needs. Our intent was to develop this robotics software to provide enabling technology to emerging applications that apply the c-space abstraction, such as advanced motion planning, teleoperation supervision, mechanism functional analysis, and design tools. This final report presents the research results and technical achievements of this LDRD project. Key results and achievements included (1) a hybrid Common LISP/C prototype that implements the basic C-Space abstraction, (2) a new, generic, algorithm for constructing hierarchical geometric representations, and (3) a C++ implementation of an algorithm for fast distance computation, interference detection, and c-space point-classification. Since the project conclusion, motion planning researchers in Sandia`s Intelligent Systems and Robotics Center have been using the CSTk libcstk.so C++ library. The code continues to be used, supported, and improved by projects in the ISRC.

    Final technical report for research performed by Dr. Thomas G. Jenkins in collaboration with Professor Dalton D. Schnack on SciDAC Cooperative Agreement: Center for Wave Interactions with Magnetohydrodyanics, DE-FC02-06ER54899, for the period of 8/15/06 - 8/14/11. This report centers on the Slow MHD physics campaign work performed by Dr. Jenkins while at UW-Madison and then at Tech-X Corporation. To make progress on the problem of RF induced currents affect magnetic island evolution in toroidal plasmas, a set of research approaches are outlined. Three approaches can be addressed in parallel. These are: (1) Analytically prescribed additional term in Ohm's law to model the effect of localized ECCD current drive; (2) Introduce an additional evolution equation for the Ohm's law source term. Establish a RF source 'box' where information from the RF code couples to the fluid evolution; and (3) Carry out a more rigorous analytic calculation treating the additional RF terms in a closure problem. These approaches rely on the necessity of reinvigorating the computation modeling efforts of resistive and neoclassical tearing modes with present day versions of the numerical tools. For the RF community, the relevant action item is - RF ray tracing codes need to be modified so that general three-dimensional spatial information can be obtained. Further, interface efforts between the two codes require work as well as an assessment as to the numerical stability properties of the procedures to be used.

    Department of Energy Participation in the Rawlins UCG Demonstration Project began officially on November 9, 1987. Even though their financial participation began at this time, they will receive technical information from the start of the project which was on January 1, 1987. The Rawlins UCG Demonstration Project is progressing in Phase I with the majority of the emphasis on facility design, site characterization and the environmental work. The site characterization field work is estimated to be completed by the end of February with the final report completion towards the end of Phase I. The facility design effort is close to the 40% level. It is anticipated that all permits will be applied for in Phase I and most of them will be granted by the end of Phase I. The obtaining of the private financing continues to be a major activity in the project. All of the financing must be in place before the continuation for DOE funding to Phase II will be applied for.

    Pendergrass, R.A. II; Raffensperger, C.; Hesketh, R.P.

    1996-02-29

    The goal of this project is to investigate the conditions in which volatiles will burn within both the dense and freeboard regions of fluidized beds. Experiments using a fluidized bed operated at incipient fluidization are being conducted to characterize the effect of particle surface area, initial fuel concentration, and particle type on the inhibition of volatiles within a fluidized bed. A review of the work conducted under this grant is presented in this Final Technical Report. Both experimental and theoretical work have been conducted to examine the inhibition of the combustion by the fluidized bed material, sand. It has been shown that particulate phase at incipient fluidization inhibits the combustion of propane by free radical destruction at the surface of sand particles within the particulate phase. The implications of these findings is that at bed temperatures lower than the critical temperatures, gas combustion can only occur in the bubble phase or at the top surface of a bubbling fluidized bed. In modeling fluidized bed combustion this inhibition by the particulate phase should be included.

    Surko, Clifford M.

    2013-10-02

    The objective of this research is to develop new tools to manipulate antimatter plasmas and to tailor them for specific scientific and technical uses. The work has two specific objectives. One is establishing the limits for positron accumulation and confinement in the form of single-component plasmas in Penning-Malmberg traps. This technique underpins a wealth of antimatter applications. A second objective is to develop an understanding of the limits for formation of cold, bright positron beams. The research done in this grant focused on particular facets of these goals. One focus was extracting tailored beams from a high-field Penning-Malmberg trap from the magnetic field to form new kinds of high-quality electrostatic beams. A second goal was to develop the technology for colder trap-based beams using a cryogenically cooled buffer gas. A third objective was to conduct the basic plasma research to develop a new high-capacity multicell trap (MCT) for research with antimatter. Progress is reported here in all three areas. While the goal of this research is to develop new tools for manipulating positrons (i.e., the antiparticles of electrons), much of the work was done with test electron plasmas for increased data rate. Some of the techniques developed in the course of this work are also relevant to the manipulation and use of antiprotons.

    1980-05-23

    This technical memorandum was prepared to: (1) describe a typical basalt radionuclide repository site, (2) describe geologic and hydrologic processes associated with regional radionuclide transport in basalts, (3) define the parameters required to model regional radionuclide transport from a basalt repository site, and (4) develop a ''conceptual model'' of radionuclide transport from a basalt repository site. In a general hydrological sense, basalts may be described as layered sequences of aquifers and aquitards. The Columbia River Basalt, centered near the semi-arid Pasco Basin, is considered by many to be typical basalt repository host rock. Detailed description of the flow system including flow velocities with high-low hydraulic conductivity sequences are not possible with existing data. However, according to theory, waste-transport routes are ultimately towards the Columbia River and the lengths of flow paths from the repository to the biosphere may be relatively short. There are many physical, chemical, thermal, and nuclear processes with associated parameters that together determine the possible pattern of radionuclide migration in basalts and surrounding formations. Brief process descriptions and associated parameter lists are provided. Emphasis has been placed on the use of the distribution coefficient in simulating ion exchange. The use of the distribution coefficient approach is limited because it takes into account only relatively fast mass transfer processes. In general, knowledge of hydrogeochemical processes is primitive.

    The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) is the follow-on ocean color instrument to the Coastal Zone Color Scanner (CZCS), which ceased operations in 1986, after an eight-year mission. SeaWiFS was launched on 1 August 1997, on the SeaStar satellite, built by Orbital Sciences Corporation (OSC). The SeaWiFS Project at the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC), undertook the responsibility of documenting all aspects of this mission, which is critical to the ocean color and marine science communities. This documentation, entitled the SeaWiFS Technical Report Series, is in the form of NASA Technical Memorandum Number 104566 and 1998-104566. All reports published are volumes within the series. This particular volume, which is the last of the so-called Prelaunch Series serves as a reference, or guidebook, to the previous 42 volumes and consists of 6 sections including: an addenda, an errata, an index to key words and phrases, lists of acronyms and symbols used, and a list of all references cited. The editors have published a cumulative index of this type after every five volumes.

    2014-05-01

    Mining took place in France between 1945 and 2001 during which time ~210 different sites were exploited and/or explored. A total of 76 Kt of uranium was produced, 52 Mt of ore was extracted, but also 200 Mt of waste rocks was produced, the majority of which, with uranium levels corresponding to the natural environment. So far, the processes of arenisation and technic soil formation in waste rock piles are not well understood but have important implications for understanding the environmental impact and long-term speciation of uranium. Understanding weathering processes in waste rock piles is essential to determine their environmental impact. The main objectives of this work are to assess 1) the micromorphological features and neo-formed U-bearing phases related to weathering and 2) the processes behind arenisation of the rock pile. The site that was chosen is the Vieilles Sagnes waste rock pile in Fanay (Massif Central France) that represents more or less hydrothermally altered granitic rocks that have been exposed to weathering since the construction of the waste rock pile approximately 50 years ago. Two trenches were excavated to investigate the vertical differentiation of the rock pile. This site serves as a key location for studying weathering processes of waste rock piles, as it has not been reworked after initial construction and has therefore preserved information on the original mineralogy of the waste rock pile enabling us to access post emplacement weathering processes. The site is currently overgrown by moss, meter high ferns and small trees. At present day the rock pile material can be described as hydrothermally altered rocks and rock fragments within a fine-grained silty clay matrix exposed to surface conditions and weathering. A sandy "paleo" technic soil underlies the waste rock pile and functions as a natural liner by adsorption of uranium on clay minerals. Post-mining weathering of rock-pile material is superimposed on pre-mining hydrothermal and

    SciTech Connect

    Goldstein, B.

    1988-02-01

    The New Mexico Solar Energy Institute at NMSU has conducted a two-year investigation into the technical and economic feasibility of using the buffalo gourd plant as an energy feedstock in eastern New Mexico. The New Mexico buffalo gourd project conducted field planting trials to determine optimum planting density, fertilizer levels, and irrigation regime. Starchy roots produced by the field plantings were evaluated as an ethanol feedstock at both laboratory and pilot scale. These studies indicate that buffalo gourd is well suited for root production in eastern New Mexico. Current cultivars of buffalo gourd can be most efficiently produced under dry land farming conditions with little, if any, supplemental fertilizer. Traditional plant breeding techniques can be profitably employed on the buffalo gourd to breed a size and shape of root more easily harvested by existing farm machinery. Because of its sensitivity to root rot, buffalo gourd must be grown in well drained soils. Finally, buffalo gourd has been shown to be an excellent feedstock for ethanol production provided necessary pre-fermentation processing (chopping of roots) is performed correctly. A model was created to determine the economic feasibility of growing buffalo gourd in eastern New Mexico. It was determined that the net return to a farmer in eastern New Mexico can be higher planting buffalo gourd than many traditionally grown crops because of buffalo gourd's low water and fertilizer requirements. The model further indicates that net return is heavily influenced by root yield. Continued research is needed to optimize buffalo gourd root yield, as well as root size and shape, disease resistance, etc. A clearly defined R and D agenda and commercialization strategy is presented and discussed. Buffalo gourd has been demonstrated to have high potential as an alternative feedstock for ethanol production in eastern New Mexico. 128 refs., 9 figs., 28 tabs.

    This is the final technical report for the U.S. Department of Energy-funded program, DE-0002981: DeepCwind Consortium Research Program. The project objective was the partial validation of coupled models and optimization of materials for offshore wind structures. The United States has a great opportunity to harness an indigenous abundant renewable energy resource: offshore wind. In 2010, the National Renewable Energy Laboratory (NREL) estimated there to be over 4,000 GW of potential offshore wind energy found within 50 nautical miles of the US coastlines (Musial and Ram, 2010). The US Energy Information Administration reported the total annual US electric energy generation in 2010 was 4,120 billion kilowatt-hours (equivalent to 470 GW) (US EIA, 2011), slightly more than 10% of the potential offshore wind resource. In addition, deep water offshore wind is the dominant US ocean energy resource available comprising 75% of the total assessed ocean energy resource as compared to wave and tidal resources (Musial, 2008). Through these assessments it is clear offshore wind can be a major contributor to US energy supplies. The caveat to capturing offshore wind along many parts of the US coast is deep water. Nearly 60%, or 2,450 GW, of the estimated US offshore wind resource is located in water depths of 60 m or more (Musial and Ram, 2010). At water depths over 60 m building fixed offshore wind turbine foundations, such as those found in Europe, is likely economically infeasible (Musial et al., 2006). Therefore floating wind turbine technology is seen as the best option for extracting a majority of the US offshore wind energy resource.

    This research program examined the heterogeneous reaction kinetics and reaction dynamics of surface chemical processes which are of direct relevance to efficient energy production, condensed phase reactions, and mateials growth including nanoscience objectives. We have had several notable scientific and technical successes. Illustrative highlights include: (1) a thorough study of how one can efficiently produce synthesis gas (SynGas) at relatively low Rh(111) catalyst temperatures via the reaction CH{sub4}+1/2 O{sub2} {r_arrow} CO+2H{sub2}. In these studies methane activation is accomplished utilizing high-kinetic energy reagents generated via supersonic molecular beams, (2) experiments which have incisively probed the partial oxidation chemistry of adsorbed 1- and 2- butene on Rh and ice, as well as partial oxidation of propene on Au; (3) investigation of structural changes which occur to the reconstructed (23x{radical}3)-Au(111) surface upon exposure to atomic oxygen, (4) a combined experimental and theoretical examination of the fundamental atomic-level rules which govern defect minimization during the formation of self-organizing stepped nanostructures, (5) the use of these relatively defect-free nanotemplates for growing silicon nanowires having atomically-dimensioned widths, (6) a combined scanning probe and atomic beam scattering study of how the presence of self-assembling organic overlayers interact with metallic supports substrates - this work hs led to revision of the currently held view of how such adsorbates reconfigure surface structure at the atomic level, (7) an inelastic He atom scattering study in which we examined the effect of chain length on the low-energy vibrations of alkanethiol striped phase self-assembled monolayers on Au(111), yielding information on the forces that govern interfacial self-assembly, (8) a study of the vibrational properties of disordered films of SF{sub6} adsorbed on Au(111), and (9) a study of the activated chemistry and

    DNV Renewables (USA) Inc. (DNV KEMA) received a grant from the U.S. Department of Energy (DOE) to develop the curriculum for a series of short courses intended to address Topic Area 5 Workforce Development, one of the focus areas to achieve the goals outlined in 20% Wind by 2030: Increasing Wind Energy's Contribution to Electricity Supply. The aim of the curriculum development project was to provide material for instructors to use in a training program to help professionals transition into careers in wind energy. Under this grant DNV KEMA established a knowledge boosting program for the wind energy industry with the following objectives: 1. Develop technical training curricula and teaching materials for six key topic areas that can be implemented in a flexible format by a knowledgeable instructor. The topic areas form a foundation that can be leveraged for subsequent, more detailed learning modules (not developed in this program). 2. Develop an implementation guidance document to accompany the curricula outlining key learning objectives, implementation methods, and guidance for utilizing the curricula. This curriculum is intended to provide experienced trainers course material that can be used to provide course participants with a basic background in wind energy and wind project development. The curriculum addresses all aspects of developing a wind project, that when implemented can be put to use immediately, making the participant an asset to U.S. wind industry employers. The curriculum is comprised of six short modules, together equivalent in level of content to a one-semester college-level course. The student who completes all six modules should be able to understand on a basic level what is required to develop a wind project, speak with a reasonable level of confidence about such topics as wind resource assessment, energy assessment, turbine technology and project economics, and contribute to the analysis and review of project information.

    Schobert, H.H.; Tomic, J.

    1993-05-25

    The objective of this study was to examine the processes in coal/petroleum coprocessing systems which led to coke formation. Specifically, the interactions between the petroleum residue and coal, leading to retrogressive products, were investigated. Five coals were reacted with five model compounds in order to investigate the coal conversions in a variety of solvents and to determine the role of the solvent in promoting or inhibiting coal conversion. The selected model compounds range from paraffinic to fully aromatic and were chosen as representative of types of compounds that are found in petroleum residua. Coprocessing experiments were conducted using the five coals and three petroleum residua. The effect of temperature on coal conversions was crucial. The coal conversions at 350 and 400{degree}C seem to be governed by the nature of the coal and to a lesser extent by the petroleum residua. Negative coal conversions were observed above 400{degree}C indicating that retrogressive processes had occurred. At temperatures higher than 400{degree}C, the petroleum residua undergo physical and chemical transformations and the influence of the petroleum residua on coal conversions is significant. The structural features of the residues indicated that the residues were predominately coal-derived. An overall increase in aromaticity was observed with increasing temperature which was also accompanied by loss of oxygen functional groups. The retrogressive reactions with non-caking coals involve carbonyl and carboxyl group leading to a final solid characterized by a cross-linked structure. In the case of caking coal, these reactions are governed by loss of aromatic oxygen groups and loss of alkyl groups.

    This four-year research project has advanced the fundamental knowledge of grain boundary (GB) complexions (i.e., "two-dimensional interfacial phases") and associated GB "phase" transitions in several grounds. First, a bilayer interfacial phase, which had been directly observed by microscopy only in complex ceramic systems in prior studies, has been identified in simpler systems such as Au-doped Si and Bi-doped Ni in this study, where the interpretations of the their formation mechanisms and microscopic images are less equivocal. Second, convincing evidence for the existence of a first-order GB transition from a nominally "clean" GB to a bilayer adsorption interfacial phase has been revealed for Au-doped Si; the confirmation of the first-order nature of interfacial transitions at GBs, which was rare in prior studies, is scientifically significant and technologically important. Third, the bilayer interfacial phase discovered in Bi-doped Ni has been found to be the cause of the mysterious liquid metal embrittlement phenomenon in this system; the exact atomic level mechanism of this phenomenon has puzzled the materials and physics communities for over a century. Finally, significant advancements have been made to establish phenomenological thermodynamic models for GB complexions and transitions. Since GB complexions can control the transport, mechanical and physical properties of a broad range of metallic and ceramic materials, the fundamental knowledge generated by this project can have broad impacts on materials design in general. In this regard, understanding and controlling GB phase behaviors (complexions and transitions) can be an important component for the "Materials Genome" project.

    The influence of a presintering of silicon on the final properties of reaction bonded silicon nitride has been studied using scanning electron and optical microscopy, x-ray diffraction analysis, 4 pt. bend test, and mecury intrusion porosimetry. It has been shown that presintering at 1050/sup 0/C will not affect the final nitrided properties. At 1200/sup 0/C, the oxide layer is removed, promoting the formation of B-phase silicon nitride. Presintering at 1200/sup 0/C also results in compact weight loss due to the volatilization of silicon, and the formation of large pores which severely reduce nitrided strength. The development of the structure of sintered silicon compacts appears to involve a temperature gradient, with greater sintering observed near the surface.

  2. Final Technical Progress Report Long term risk from actinides in the environment: Modes of mobility

    SciTech Connect

    Thomas B. Kirchner

    2002-03-22

    The key source of uncertainty in assessing actinide mobility is the relative importance of transport by: (1) wind erosion, (2) water erosion, and (3) vertical migration. Each of these three processes depends on several environmental factors and they compete with one another. A scientific assessment of the long-term risks associated with actinides in surface soils depends on better quantifying each of these three modes of mobility. The objective from our EMSP study was to quantify the mobility of soil actinides by wind erosion, water erosion, and vertical migration at three semiarid sites where actinide mobility is a key technical, social and legal issue. This EMSP project was the first to evaluate all three factors at a site. The approach has been to investigate both short- and long-term issues based on field and lab studies and model comparisons. Our results demonstrate the importance of incorporating threshold responses into a modeling framework that accounts for environmental factors and natural disturbances that trigger large changes in actinide mobility. The study measured erosional losses of sediment and fallout cesium (an actinide analogue) from field plots located near WIPP in 1998. The results highlight the large effect of burning as a disturbance on contaminant transport and mobility via runoff and erosion. The results show that runoff, erosion, and actinide transport are (1) strongly site specific-differences in radionuclide transport between WIPP and Rocky Flats differed by a factor of twelve because of soil and vegetation differences, and (2) are strongly impacted by disturbances such as fire, which can increase runoff, erosion, and actinide transport by more than an order of magnitude. In addition, a laboratory experiment using soil columns was conducted to investigate the vertical transport of contaminants in sandy soils. Nine columns of soil collected from the vicinity of the WIPP site were prepared. The column consisted of a piece of PVC pipe 20 cm

    The UCLA Plasma Simulation Group is a major partner of the “Community Petascale Project for Accelerator Science and Simulation”. This is the final technical report. We include an overall summary, a list of publications, progress for the most recent year, and individual progress reports for each year. We have made tremendous progress during the three years. SciDAC funds have contributed to the development of a large number of skeleton codes that illustrate how to write PIC codes with a hierarchy of parallelism. These codes cover 2D and 3D as well as electrostatic solvers (which are used in beam dynamics codes and quasi-static codes) and electromagnetic solvers (which are used in plasma based accelerator codes). We also used these ideas to develop a GPU enabled version of OSIRIS. SciDAC funds were also contributed to the development of strategies to eliminate the Numerical Cerenkov Instability (NCI) which is an issue when carrying laser wakefield accelerator (LWFA) simulations in a boosted frame and when quantifying the emittance and energy spread of self-injected electron beams. This work included the development of a new code called UPIC-EMMA which is an FFT based electromagnetic PIC code and to new hybrid algorithms in OSIRIS. A new hybrid (PIC in r-z and gridless in φ) algorithm was implemented into OSIRIS. In this algorithm the fields and current are expanded into azimuthal harmonics and the complex amplitude for each harmonic is calculated separately. The contributions from each harmonic are summed and then used to push the particles. This algorithm permits modeling plasma based acceleration with some 3D effects but with the computational load of an 2D r-z PIC code. We developed a rigorously charge conserving current deposit for this algorithm. Very recently, we made progress in combining the speed up from the quasi-3D algorithm with that from the Lorentz boosted frame. SciDAC funds also contributed to the improvement and speed up of the quasi-static PIC

    Power through Policy: 'Best Practices' for Cost-Effective Distributed Wind is a U.S. Department of Energy (DOE)-funded project to identify distributed wind technology policy best practices and to help policymakers, utilities, advocates, and consumers examine their effectiveness using a pro forma model. Incorporating a customized feed from the Database of State Incentives for Renewables and Efficiency (DSIRE), the Web-based Distributed Wind Policy Comparison Tool (Policy Tool) is designed to assist state, local, and utility officials in understanding the financial impacts of different policy options to help reduce the cost of distributed wind technologies. The project's final products include the Distributed Wind Policy Comparison Tool, found at www.windpolicytool.org, and its accompanying documentation: Distributed Wind Policy Comparison Tool Guidebook: User Instructions, Assumptions, and Case Studies. With only two initial user inputs required, the Policy Tool allows users to adjust and test a wide range of policy-related variables through a user-friendly dashboard interface with slider bars. The Policy Tool is populated with a variety of financial variables, including turbine costs, electricity rates, policies, and financial incentives; economic variables including discount and escalation rates; as well as technical variables that impact electricity production, such as turbine power curves and wind speed. The Policy Tool allows users to change many of the variables, including the policies, to gauge the expected impacts that various policy combinations could have on the cost of energy (COE), net present value (NPV), internal rate of return (IRR), and the simple payback of distributed wind projects ranging in size from 2.4 kilowatts (kW) to 100 kW. The project conducted case studies to demonstrate how the Policy Tool can provide insights into 'what if' scenarios and also allow the current status of incentives to be examined or defended when necessary.

    boron results in the formation of parasitic phases such as MgB4, MgB7, etc. Such parasitic phases are a primary element of the connectivity problem, in which even though a sample powder may contain grains of high-quality MgB2, adjacent grains are surrounded by intergrowths of parasitic phases so that current trans-port is badly degraded. The best results to date have been obtained using boron powder produced long ago for a rocket propellant development project. The synthesis process was complex and is now largely lost, and the manufacturing equipment has long since been scrapped. The last batch of the powder has been used during recent years to support MgB2 R&D at several labs, but supplies are dwindling. ATC has identified a first application of its plasma torch to synthesize phase-pure amorphous boron flake using a rapid-quench splat technique. Inexpensive technical-grade boron would be purified of contaminants, then dispersed as an aerosol in inert gas and passed through the plasma torch to melt it into a spray. The spray would be splat-condensed on a rotating drum to form pure amorphous flake. The process would begin with technical-grade boron powder, having good stoichiometric purity, nanoscale particles, but significant contamination of MgO and crystalline boron. We used wet chemistry to remove B2O3 completely and reduced the MgO impurity, and analyzed the particle size distribution using a Coulter counter and the phase composition using X-ray diffrac-tion (XRD). The next step will be to build an rf plasma torch with a recirculating single-component aerosol feed and the cooled splat drum and collector, and undertake process devel-opment for amorphous boron powder. This revised goal has two benefits. First, it is an easier technology than our ultimate goal of a multi-component laminar flow torch. We have been counseled by those experienced in plasma torch technology that our ultimate goal will require a torch that should be feasible but has never been attempted. It

    Since the grant was renewed in 2000 and 2003 final technical reports of the grant have been previously submitted for those years. For that reason this final technical report covers the last four years of the grant. We had an exceptionally successful and productive last four years under the support of the grant. Our progress takes three different aspects, described in more detail below: 1.1 instrumentation, infrastructure, and other research support at Sector 20 of the Advanced Photon Source (APS); 1.2 research on which Profs. Stern or Seidler were PI?s; and 1.3 research on which Profs. Stern or Seidler were co-PI?s or where Drs. Dale Brewe or Julie Cross were authors or co-authors. Drs. Brewe and Cross are the two research scientists (permanently stationed at sector 20) who are supported by the grant. They provide support to the scientific goals of the grant and more broadly provide research support for many general users at Sector 20. Finally, in section 1.4 we provide a complete list of publications resulting from funding in the grant on which at least one of Stern, Seidler, Cross, or Brewe were co-authors. Given the inclusion of operations funding in the grant, this is of course a subset of the full scientific impact of the grant.

    2010-10-11

    A team of Texas AgriLife Research, Baylor University and University of Texas at Arlington researchers studied the biology and ecology of Prymnesium parvum (golden algae) in Texas lakes using a three-fold approach that involved system-wide monitoring, experimentation at the microcosm and mesocosm scales, and mathematical modeling. The following are conclusions, to date, regarding this organism's ecology and potential strategies for mitigation of blooms by this organism. In-lake monitoring revealed that golden algae are present throughout the year, even in lakes where blooms do not occur. Compilation of our field monitoring data with data collected by Texas Parks and Wildlife and Brazos River Authority (a period spanning a decade) revealed that inflow and salinity variables affect bloom formations. Thresholds for algae populations vary per lake, likely due to adaptations to local conditions, and also to variations in lake-basin morphometry, especially the presence of coves that may serve as hydraulic storage zones for P. parvum populations. More specifically, our in-lake monitoring showed that the highly toxic bloom that occurred in Lake Granbury in the winter of 2006/2007 was eliminated by increased river inflow events. The bloom was flushed from the system. The lower salinities that resulted contributed to golden algae not blooming in the following years. However, flushing is not an absolute requirement for bloom termination. Laboratory experiments have shown that growth of golden algae can occur at salinities ~1-2 psu but only when temperatures are also low. This helps to explain why blooms are possible during winter months in Texas lakes. Our in-lake experiments in Lake Whitney and Lake Waco, as well as our laboratory experiments, revealed that cyanobacteria, or some other bacteria capable of producing algicides, were able to prevent golden algae from blooming. Identification of this organism is a high priority as it may be a key to managing golden algae blooms

    hydrogen, methane, and carbon dioxide was repeatedly demonstrated in batch reactors varying in size from 50 mL to 7.6 L. The different wood sources (e.g., swamp maple, poplar, and commercial wood flour) were converted in the presence of a heterogeneous catalyst and base at relatively low temperatures (e.g., 310°C) at sub-critical pressures sufficient to maintain the liquid phase. Both precious metal and base metal catalysts were found to be active for the liquid phase hydrolysis and reforming of wood. Pt-based catalysts, particularly Pt-Re, were shown to be more selective toward breaking C-C bonds, resulting in a higher selectivity to hydrogen versus methane. Ni-based catalysts were found to prefer breaking C-O bonds, favoring the production of methane. The project showed that increasing the concentration of base (base to wood ratio) in the presence of Raney Ni catalysts resulted in greater selectivity toward hydrogen but at the expense of increasing the production of undesirable organic acids from the wood, lowering the amount of wood converted to gas. It was shown that by modifying Ni-based catalysts with dopants, it was possible to reduce the base concentration while maintaining the selectivity toward hydrogen and increasing wood conversion to gas versus organic acids. The final stage of the project was the construction and testing of a demonstration unit for H2 production. This continuous flow demonstration unit consisted of wood slurry and potassium carbonate feed pump systems, two reactors for hydrolysis and reforming, and a gas-liquid separation system. The technical challenges associated with unreacted wood fines and Raney Ni catalyst retention limited the demonstration unit to using a fixed bed Raney Ni catalyst form. The lower activity of the larger particle Raney Ni in turn limited the residence time and thus the wood mass flow feed rate to 50 g min-1 for a 1 wt% wood slurry. The project demonstrated continuous H2 yields with unmodified, fixed bed Raney Ni

    To evaluate the technical and economic barriers to innovative natural gas storage technologies, advantages and disadvantages of several end use applications were analyzed, including on-grid deliverability of natural gas, transporting natural gas to off-grid end users, and storage of natural gas at an off-grid end user's site. Three basic innovative approaches were investigated: (1) separation of the higher molecular weight components of the pipeline gas and storage of the separated ethane, propane, butane, etc., as a liquid; (2) separation of the components with storage in the separating media; and (3) storage of the pipeline gas without changing its composition.

    Under pulverized coal combustion conditions, NO{sub x} formed during the release of volatile matter far exceed NO{sub x} formed from combustion of the resulting char. It is believed that interactions of NO{sub x} with char is responsible for the reduced NO{sub x} formation from the combustion of char. The goal of this research is to assess the potential technical and economical benefits of co-firing coal-char blends in pulverized coal boilers to reduce NO{sub x}. The rationale for the proposed research is that the presence of char in the flame during the initial stages of combustion may provide catalytic activity for reduction of NO{sub x} produced from volatile nitrogen. This project is a cooperative effort between the Illinois State Geological Survey (ISGS) and BYU/ACERC. Seven hundred and fifty pounds of three coal-char blends containing 12.5%, 25%, and 50% char and 125 pounds of a coal-activated carbon blend containing 12.5% activated carbon were prepared. The volatile matter contents of the blends ranged from 27.3 to 35.6% (dry basis). Char (16.2 wt% volatile matter) was made from an Illinois No. 6 coal (Peabody Coal Company) in a continuous feed charring oven under mild gasification conditions. Nine combustion tests will be performed with the coal and blends in a 0.5--1.0 MBtu/hr combustor located at BYU. Combustion data will be analyzed to determine the effect of blend type, stoichiometry, and flame temperature on NO{sub x} formation, ignition characteristics, flame stability, and combustion efficiency. A four month no-cost extension has been requested for the project. The results of the combustion tests will be reported in the final technical report in December 1993.

    2007-08-23

    The City of Brockton, Massachusetts sought to install New England’s largest solar array at a remediated brownfield site on Grove Street. The 425-kilowatt solar photovoltaic array – or “Brightfield” – was installed in an urban park setting along with interpretive displays to maximize the educational opportunities. The “Brightfield” project included 1,395 310-Watt solar panels connected in “strings” that span the otherwise unusable 3.7-acre site. The project demonstrated that it is both technically and economically feasible to install utility scale solar photovoltaics on a capped landfill site. The US Department of Energy conceived the Brightfields program in 2000, and Brockton’s Brightfield is the largest such installation nationwide. Brockton’s project demonstrated that while it was both technically and economically feasible to perform such a project, the implementation was extremely challenging due to the state policy barriers, difficulty obtaining grant funding, and level of sophistication required to perform the financing and secure required state approvals. This demonstration project can be used as a model for other communities that wish to implement “Brownfields to Brightfields” projects; 2) implementing utility scale solar creates economies of scale that can help to decrease costs of photovoltaics; 3) the project is an aesthetic, environmental, educational and economic asset for the City of Brockton.

    In order to address the issue of technological progress, most integrated assessment models have incorporated methods to account for autonomous energy efficiency improvement, the natural tendency of an economy to find more efficient ways to produce energy services. Although the treatment of technical changes as an autonomous event is a reasonable modeling convenience, it is not a statement of actual cause and effect. The purpose of this research project is to examine the responsiveness of a particular technology, solar photovoltaic electricity generation, to research and development expenditures by the government and private industry. The goal is to be able to model how the technology can be expected to respond to future government expenditures. The first step was to develop a database of government expenditures on solar photovoltaic research and development. The next step was to develop an analytical dynamic optimization model that would allow the characterization of the important factors in the R&D process and the demonstration of generalizable principles of optimal investment in the R&D process. There is now a solid starting point for research into the relation between government spending on technology research and the response of the technology in terms of technical efficiency.

    Hundreds of aging nuclear materials processing facilities within the Department of Energy`s (DOE) Weapons Complex are now being shut down and deactivated. These facilities, situated throughout the United States, will require a monumental effort to clean up safely and with minimal environmental insult. Current cleanup technologies tend to be labor intensive and expensive, they produce an unacceptably large volume of waste, and they expose workers to radioactive and other hazardous substances. This document describes an emerging program designed to develop and demonstrate new technical approaches to the decontamination and decommissioning (D&D) program for DOE`s nuclear materials processing facilities. Sponsored by the DOE Office of Technology Development within the Office of Environmental Restoration and Waste Management (EM), the program seeks to integrate the strengths of DOE`s technical, managerial, and systems engineering capabilities with those of industry, universities, and other government agencies. Once developed, these technologies will help to provide US industry with a competitive edge in the worldwide market that exists for improved environmental restoration and D&D services.

    The purpose of the Solar America Initiative: Solar Outreach and Communications grant was to promote better communications among stakeholders; address infrastructure barriers to solar energy; and coordinate with industry, the U.S. Department of Energy, national laboratories, states, cities and counties. The Interstate Renewable Energy Council (IREC), a non-profit organization formed in 1982, approached this grant project by establishing a wide range of communication and outreach activities including newsletters, workshops, webinars, model practices and publications; by advancing easy and fair hook-up rules to the utility grid; and by upgrading training based on industry competency standards. The Connecting to the Grid project and the Solar Codes and Standards Public Hearings project offered communication coupled with technical assistance to overcome interconnection, net metering and other regulatory and program barriers. The Workforce Development Project tackled building a strong workforce through quality training and competency assessment programs. IREC's web site, the semi-monthly state and stakeholder newsletter and the metrics report resulted in better communications among stakeholders. Workshops and phone seminars offered technical assistance and kept stakeholders up-to-date on key issues. All of these activities resulted in implementing sustainable solutions to institutional and market barriers to solar energy and getting the right information to the right people.

  3. Powder Metallurgy of Uranium Alloy Fuels for TRU-Burning Reactors Final Technical Report

    McDeavitt, Sean M

    2011-04-29

    Overview Fast reactors were evaluated to enable the transmutation of transuranic isotopes generated by nuclear energy systems. The motivation for this was that TRU isotopes have high radiotoxicity and relatively long half-lives, making them unattractive for disposal in a long-term geologic repository. Fast reactors provide an efficient means to utilize the energy content of the TRUs while destroying them. An enabling technology that requires research and development is the fabrication metallic fuel containing TRU isotopes using powder metallurgy methods. This project focused upon developing a powder metallurgical fabrication method to produce U-Zr-transuranic (TRU) alloys at relatively low processing temperatures (500ºC to 600ºC) using either hot extrusion or alpha-phase sintering for charecterization. Researchers quantified the fundamental aspects of both processing methods using surrogate metals to simulate the TRU elements.

    The electronic properties of boron-rich icosahedral clusters were studied as a means of understanding the electronic structure of the icosahedral borides such as boron carbide. A lower bound was estimated on bipolaron formation energies in B/sub 12/ and B/sub 11/C icosahedra, and the associated distortions. While the magnitude of the distortion associated with bipolaron formation is similar in both cases, the calculated formation energies differ greatly, formation being much more favorable on B11C icosahedra. The stable positions of a divalent atom relative to an icosahedral borane was also investigated, with the result that a stable energy minimum was found when the atom is at the center of the borane, internal to the B/sub 12/ cage. If incorporation of dopant atoms into B/sub 12/ cages in icosahedral boride solids is feasible, novel materials might result. In addition, the normal modes of a B/sub 12/H/sub 12/ cluster, of the C/sub 2/B/sub 10/ cage in para-carborane, and of a B/sub 12/ icosahedron of reduced (D sub 3d) symmetry, such as is found in the icosahedral borides, were calculated. The nature of these vibrational modes will be important in determining, for instance, the character of the electron-lattice coupling in the borides, and in analyzing the lattice contribution to the thermal conductivity.

    Through the support from the Department of Energy, NARUC has educated thousands of stakeholders, including Public Utility Commissioners, commission staff, and State energy officials on solar energy technology, implementation, and policy. During the lifetime of this grant, NARUC staff engaged stakeholders in policy discussions, technical research, site visits, and educational meetings/webinars/materials that provided valuable education and coordination on solar energy technology and policy among the States. Primary research geared toward State decision-makers enabled stakeholders to be informed on current issues and created new solar energy leaders throughout the United States. Publications including a Frequently Asked Questions guide on feed-in tariffs and a legal analysis of state implementation of feed-in tariffs gave NARUC members the capacity to understand complex issues related to the economic impacts of policies supportive of solar energy, and potential paths for implementation of technology. Technical partnerships with the National Renewable Energy Laboratory (NREL) instructed NARUC members on feed-in tariff policy for four States and solar PV resource assessment in seven States, as well as economic impacts of solar energy implementation in those States. Because many of the States in these technical partnerships had negligible amounts of solar energy installed, this research gave them new capacity to understand how policies and implementation could impact their constituency. This original research produced new data now available, not only to decision-makers, but also to the public at-large including educational institutions, NGOs, consumer groups, and other citizens who have an interest in solar energy adoption in the US. Under this grant, stakeholders engaged in several dialogs. These educational opportunities brought NARUC members and other stakeholders together several times each year, shared best practices with State decision-makers, fostered

    Significant progress has been made in laying the foundations of a complexity theory of neural networks. The fundamental complexity classes have been identified and studied. The class of problems solvable by small, shallow neural networks has been found to be the same class even if (1) probabilistic behaviour (2)Multi-valued logic, and (3)analog behaviour, are allowed (subject to certain resonable technical assumptions). Neural networks can be made provably fault-tolerant by physically separating the summation units from the thresholding units. New results have also been obtained on the complexity of approximation, communication complexity, the complexity of learning from examples and counterexamples, learning with multi-valued neurons, exponential lower bounds for restricted neural networks, and fault tolerance in distributed computation.

    This demonstration project contributes to the knowledge base in the area of fuel cells in stationary applications, propane fuel cells, edge-of-grid applications for fuel cells, and energy storage in combination with fuel cells. The project demonstrated that it is technically feasible to meet the whole-house electrical energy needs of a typical upstate New York residence with a 5-kW fuel cell in combination with in-home energy storage without any major modifications to the residence or modifications to the consumption patterns of the residents of the home. The use of a fuel cell at constant output power through a 120-Volt inverter leads to system performance issues including: • relatively poor power quality as quantified by the IEEE-defined short term flicker parameter • relatively low overall system efficiency Each of these issues is discussed in detail in the text of this report. The fuel cell performed well over the 1-year demonstration period in terms of availability and efficiency of conversion from chemical energy (propane) to electrical energy at the fuel cell output terminals. Another strength of fuel cell performance in the demonstration was the low requirements for maintenance and repair on the fuel cell. The project uncovered a new and important installation consideration for propane fuel cells. Alcohol added to new propane storage tanks is preferentially absorbed on the surface of some fuel cell reformer desulfurization filters. The experience on this project indicates that special attention must be paid to the volume and composition of propane tank additives. Size, composition, and replacement schedules for the de-sulfurization filter bed should be adjusted to account for propane tank additives to avoid sulfur poisoning of fuel cell stacks. Despite good overall technical performance of the fuel cell and the whole energy system, the demonstration showed that such a system is not economically feasible as compared to other commercially available

    This project assessed the feasibility of a Power Ultra-Uprate on an existing nuclear plant. The study determined the technical and design limitations of the current components, both inside and outside the containment. Based on the identified plant bottlenecks, the design changes for major pieces of equipment required to meet the Power Ultra-Uprate throughput were determined. Costs for modified pieces of equipment and for change-out and disposal of the replaced equipment were evaluated. These costs were then used to develop capital, fuel and operating and maintenance cost estimates for the Power Ultra-Uprate plant. The cost evaluation indicates that the largest cost components are the replacement of power (during the outage required for the uprate) and the new fuel loading. Based on these results, the study concluded that, for a standard 4-loop plant, the proposed Power Ultra-Uprate is technically feasible. However, the power uprate is likely to be more expensive than the cost (per Kw electric installed) of a new plant when large capacity uprates are considered (>25%). Nevertheless, the concept of the Power Ultra-Uprate may be an attractive option for specific nuclear power plants where a large margin exists in the steam and power conversion system or where medium power increases (~600 MWe) are needed. The results of the study suggest that development efforts on fuel technologies for current nuclear power plants should be oriented towards improving the fuel performance (fretting-wear, corrosion, uranium load, manufacturing, safety) required to achieve higher burnup rather focusing on potential increases in the fuel thermal output.

    Particle Physics explores the very fundamental building blocks of our universe: the nature of forces, of space and time. By exploring very energetic collisions of sub-nuclear particles with sophisticated detectors at the colliding beam accelerators (as well as others), experimental particle physicists have established the current theory known as the Standard Model (SM), one of the several theoretical postulates to explain our everyday world. It explains all phenomena known up to a very small fraction of a second after the Big Bang to a high precision; the Higgs boson, discovered recently, was the last of the particle predicted by the SM. However, many other phenomena, like existence of dark energy, dark matter, absence of anti-matter, the parameters in the SM, neutrino masses etc. are not explained by the SM. So, in order to find out what lies beyond the SM, i.e., what conditions at the earliest fractions of the first second of the universe gave rise to the SM, we constructed the Large Hadron Collider (LHC) at CERN after the Tevatron collider at Fermi National Accelerator Laboratory. Each of these projects helped us push the boundary further with new insights as we explore a yet higher energy regime. The experiments are extremely complex, and as we push the boundaries of our existing knowledge, it also requires pushing the boundaries of our technical knowhow. So, not only do we pursue humankind’s most basic intellectual pursuit of knowledge, we help develop technology that benefits today’s highly technical society. Our trained Ph.D. students become experts at fast computing, manipulation of large data volumes and databases, developing cloud computing, fast electronics, advanced detector developments, and complex interfaces in several of these areas. Many of the Particle physics Ph.D.s build their careers at various technology and computing facilities, even financial institutions use some of their skills of simulation and statistical prowess.

    Electricore, along with partners from Quong & Associates, Inc., Honda R&D Americas (Honda), Nissan Technical Center North America (Nissan), and Toyota Motor Engineering & Manufacturing North America, Inc. (Toyota), participated in the Light Duty Fuel Cell Electric Vehicle (FCEV) Validation Data program sponsored by the Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) (Cooperative Agreement No. DE-EE0005968). The goal of this program was to provide real world data from the operation of past and current FCEVs, in order to measure their performance and improvements over time. The program was successful; 85% of the data fields requested were provided and not restricted due to proprietary reasons. Overall, the team from Electricore provided at least 4.8 GB of data to DOE, which was combined with data from other participants to produce over 33 key data products. These products included vehicle performance and fuel cell stack performance/durability. The data were submitted to the National Renewable Energy Laboratory’s National Fuel Cell Technology Evaluation Center (NREL NFCTEC) and combined with input from other participants. NREL then produced composite data products (CDP) which anonymized the data in order to maintain confidentiality. The results were compared with past data, which showed a measurable improvement in FCEVs over the past several years. The results were presented by NREL at the 2014 Fuel Cell Seminar, and 2014 and 2015 (planned) DOE Annual Merit Review. The project was successful. The team provided all of the data agreed upon and met all of its goals. The project finished on time and within budget. In addition, an extra $62,911 of cost sharing was provided by the Electricore team. All participants believed that the method used to collect, combine, anonymize, and present the data was technically and economically effective. This project helped EERE meet its mission of ensuring America’s security and prosperity by

    The initial study on nanoparticles of magnetite was carried out in an epoxy matrix. The formation of agglomerates of Fe3O4 nanoparticles was studied by mu-XRF, magnetic, TEM and SEM techniques. Because of the elevated viscosity of epoxy resin and its effect on particle agglomeration, this study was extended using less viscous polyvinyl alcohol and some sol gels as a matrix. Unlike the results found in epoxy resin, spherical agglomerates were found in a PVA matrix even at Fe3O4 concentration of up to 50%.

    The development of one or more centralized ethanol conversion facilities in the Southwestern portion of New York State is likely to be commercially feasible if either locally-produced cheese whey and/or imported corn are used as a feedstock. Development is shown to be highly profitable under a broad range of economic conditions and technical considerations. Four plant designs ranging in annual production capacity from 1.675 to 27.5 million gallons of ethanol (utilizing alternative feedstocks) are investigated. Although all are found to be economically viable, maximum profitability per unit production are obtained from a 2.5 million gallon plant using only whey. In all cases, a by-product in the form of animal feed is generated, which will result in additional revenue for the conversion facility. In the case of corn/whey plants it takes the form of a distillers dried grain. In the case of whey plants, it takes the form of a high-mineral, medium protein feed supplement for low and moderate producing dairy cattle. Both have a ready market in the region. Also the cheese whey is assumed to be deproteinized at the cheese manufacturing plant prior to delivery to an ethanol conversion plant to obtain a valuable, human-grade food protein.

    The goal of this project, sponsored by Agri-Tech Producers, LLC (ATP), the small business grantee, was to determine if the torrefaction technology, developed by North Carolina State University (NCSU), which ATP has licensed, could be feasibly deployed in a mobile unit. The study adds to the area investigated, by having ATP’s STTR Phase I team give thoughtful consideration to how to use NCSU’s technology in a mobile unit. The findings by ATP’s team were that NCSU’s technology would best perform in units 30’ by 80’ (See Spec Sheet for the Torre-Tech 5.0 Unit in the Appendix) and the technical effectiveness and economic feasibility investigation suggested that such units were not easily, efficiently or safely utilized in a forest or farm setting. (Note rendering of possible mobile system in the Appendix) Therefore, the findings by ATP’s team were that NCSU’s technology could not feasibly be deployed as a mobile unit.

    It was the goal of this research to provide the technical basis for development of a process to remove chlorine from coal prior to combustion, based on a thermal treatment process. Reaction rate constants and activation energy have been determined, and energy and mass balances performed. Substitution of a synthetic flue gas (7% 0{sub 2}, 12% CO{sub 2}, 81% N{sub 2}) for nitrogen in the tube furnace resulted in at least equivalent chlorine removal (85.5%) compared to nitrogen. The fluidized bed dechlorination system modifications have resulted in a steady increase in performance, the most recent run providing 64% reduction in chlorine concentration. Addition of supplemental heat to the column should permit attainment of the slightly higher temperatures required to attain over 80% removal of the chlorine. Calcium chloride by-product of 67% purity has been produced. A bench scale catenary grid concentrator with supplemental heating coils and limited insulation is capable of concentrating CaCl{sub 2} solution up to essentially 40%, with no sign of scale or plugging. Further development of the process should include a thorough evaluation of the use of combustion gases to serve as the fluidizing medium and to provide the energy for the thermal dechlorination process.

    It is the goal of this research to provide the technical basis for development of a process to remove chlorine from coal prior to combustion, based on a thermal treatment process. Under the reaction conditions employed, the behavior of other trace elements of concern will also be evaluated. The recovery of the chlorine removed from the coal as a marketable byproduct, calcium chloride suitable for use as a road deicer, is also being investigated using a novel absorption/crystallization device. This report presents chlorine removal and energy balances obtained on a series of runs performed at 385{degrees}C, and information on the purity of calcium chloride produced by neutralization of the hydrogen chloride trapped in the absorber. The importance of subjecting the coal to a preheating period before exposure for a few minutes at higher temperature has been verified. Chlorine removal of approximately 84% with about 90% energy recovery in the treated coal has been attained. Calcium chloride of nearly 50% purity has been produced from the absorber solution of the tube furnace. When the bench scale dechlorination unit is complete, the larger quantities of by-product calcium chloride produced should permit upgrading the product by recrystallization.

    Our objective was to develop new, self-assembling conducting polymer-inorganic nanoparticle nanoarrays (CPIN nanoarrays) comprised of nanoparticles of inorganic Li+ insertion compounds that are “wired” together with oligomeric chains of derivatives of polythiophene. Using these nanoarrays, we developed an understanding of the relationship between structure and electrochemical function for nanostructured materials. Such nanoarrays are expected to have extremely high specific energy and specific power for battery applications due to the unique structural characteristics that derive from the nanoarray. Under this award we developed several synthetic approaches to producing manganese dioxide nanoparticles (NPs). We also developed a layer-by-layer approach for immobilizing these NPs so they could be examined electrochemically. We also developed new synthetic procedures for encapsulating manganese dioxide nanoparticles within spheres of polyethylenedioxythiophene (PEDOT), a conducting polymer with excellent charge-discharge stability. These have a unique manganese dioxide core-PEDOT shell structure. We examined the structures of these systems using transmission electron microscopy, various scanning probe microscopies, and electrochemical measurements. Various technical reports have been submitted that describe the work, including conference presentations, publications and patent applications. These reports are available through http://www.osti.gov, the DOE Energy Link System.

    This report covers a Technical and Economic Feasibility Analysis of a Coal Block Mining system. This system would extract coal in large blocks rather than in small fragments as is characteristic of current mining methods. A review of background technology is carried out, leading to the development of three Block Mining concepts. One of these, the Block Corer, is selected for further evaluation. A preliminary design of the proposed Block Miner is presented. A productivity analysis is carried out, leading to the specification of a five entry section, with two block miners, two shuttle cars, and two compact bolters bolting concurrently with mining. This analysis shows that the Block Mining section is capable of outproducing an equivalent continuous miner section due to increased haulage capabilities. An economic analysis is carried out, showing cost/ton of clean coal for Block Mining to be up to 40 percent less than that for continuous mining under certain conditions. Based on these findings, it is suggested that further development of the Block Mining System be considered. A development plan is presented.

The demonstrated and maintained high production yield is a major accomplishment supporting attractive cost projections for CIS. Process R&D at successive levels of CIS production has led to the continued demonstration of the prerequisites for commitment to large-scale commercialization. Process and packaging R&D during this and previous subcontracts has demonstrated the potential for further cost and performance improvements.

    Vegetation communities were mapped at two levels in Ozark National Scenic Riverways (ONSR) usign a hybrid combination of statistical methods and photointerpretation. The primary map includes 49 cover classes, including 24 cleasses that relate to vegetation associations currenly described by the United States National Vegetation Classification Standard (USNVC: The Nature Conservancy, 1994a). The remaining types include cultural features, ruderal communities on abandoned agricultural lands, and non-vegetated classes. Overall map classification accuarcy is 63 percent. The secondary mapping level aggregates communities with similar appearance and ecologically related associations into Community Types. The resultant 33-class Community Type map has an overall classification accuracy of 77 percent and identified groups of communities based on resource management goals within the park. Important additional products include 1) a general probability map for all vegetation associations, which can be used to assess final classification certainty, and 2) individual probability maps for each association, which can be used to identify areas that have a high likelihood of supporting a given type, beyond where that type was identified in the final map products. Other secondary map products include data layers derived from primary color-infrared imagery, secondary imagery data and digital elevation models. A field key and photo guide to associations and complete community descriptions were produced, along with a photo guide of fuel conditions. Wildland fuels data were used to generate a fuels map based upon Anderson's fuels models (1982).

    The present report contains the final results obtained during July 1996--July 1998. This report should be considered in association with the Annual Progress Report submitted in July 1997 due to the fact that not all of the intermediate results reflected in the Progress Report have been included in the Final Report. The aim of the project was to build a helical hydraulic turbine prototype and demonstrate its suitability and advantages as a novel apparatus to harness hydropower from ultra low-head rivers and other free water streams such as ocean currents or rivers without dams. The research objectives of the project are: Design, optimization and selection of the hydro foil section for the helical turbine; Design of the turbine for demonstration project; Construction and testing of the turbine module; Assessing test results and determining scale-up feasibility. The research conducted under this project has substantially exceeded the original goals including designing, constructing and testing of a scaled-up triple-helix turbine, as well as developing recommendations for application of the turbine for direct water pumping in irrigation systems and for future use in wind farms. Measurements collected during two years of turbine testing are kept in the PI files.

    Shape analysis plays an important role in many applications. In particular, in molecular biology, analyzing molecular shapes is essential to the fundamental problem of understanding how molecules interact. This project aims at developing efficient and effective algorithms to characterize and analyze molecular structures using geometric and topological methods. Two main components of this project are (1) developing novel molecular shape descriptors; and (2) identifying and representing meaningful features based on those descriptors. The project also produces accompanying (visualization) software. Results from this project (09/2006-10/2009) include the following publications. We have also set up web-servers for the software developed in this period, so that our new methods are accessible to a broader scientific community. The web sites are given below as well. In this final technical report, we first list publications and software resulted from this project. We then briefly explain the research conducted and main accomplishments during the period of this project.

  11. An approach to developing independent learning and non-technical skills amongst final year mining engineering students

    2012-06-01

    There is mounting evidence to show that engineers need more than technical skills to succeed in industry. This paper describes a curriculum innovation in which so-called 'soft' skills, specifically inter-personal and intra-personal skills, were integrated into a final year mining engineering course. The instructional approach was designed to promote independent learning and to develop non-technical skills, essential for students on the threshold of becoming practising engineers. Three psychometric tests were administered at the beginning of the course to make students aware of their own and their classmates' characteristics. Substantial prescribed reading assignments preceded weekly group discussions. Several projects during the course required team work skills and application of content knowledge to real-world contexts. Results obtained from students' reflection papers, assignments related to 'soft' skills and end of course evaluations suggest that students' appreciation of the need for these skills, as well as their own perceived competence, increased during the course. Their ability to function as independent learners also increased.

    Boyer, P.D.

    1993-12-31

    The project has centered on elucidation of the mechanism of ATP synthase. The metabolic importance of ATP and the complexity of the ATP synthase have made the problem particularly important and challenging. The development of the binding change mechanism depended upon our recognition of features that were novel in bioenergetics and indeed to the field of enzymology. One important feature of mechanism is that the principal way that energy input from transmembrane proton movement is coupled to ATP formation is to drive conformational changes that cause the release of ATP readily formed and tightly bound at a catalytic site. Another is that three equivalent catalytic sites on the enzyme show strong catalytic cooperativity as they proceed sequentially through different conformations. A more speculative features is that this cooperativity and energy coupling involve a rotational movement of minor subunits relative to the catalytic subunits. During this period these studies have extended and clarified aspects of the synthase mechanism. During assessments of interactions of Mg{sup 2+} and ADP with the synthase we recognized unexpectedly that whether ADP and P{sub i}, or their complexes with Mg{sup 2+} served as substrates for ATP formation by photophosphorylation was not known. Our studies showed that MgADP and free P{sub i} act as substrates.

    We submit here a final technical report for the research program entitled: Fundamental Studies of the Chemical Vapor Deposition of Diamond, DOE Grant No. DE-FG05-88ER45345-M006. This research program was initiated in 1988 under the direction of the late Professor David A. Stevenson and was renewed in 1992. Unfortunately, at the end of 1992, just as the last phase of this work was getting underway, Professor Stevenson learned that he had developed mesothelioma, a form of cancer based on asbestos. Professor Stevenson died from that disease in February of 1994. Professor William D. Nix, the Chairman of the Materials Science department at Stanford was named the Principal Investigator. Professor Nix has assembled this final technical report. Much of the work of this grant was conducted by Mr. Paul Dennig, a graduate student who will receive his Ph.D. degree from Stanford in a few months. His research findings are described in the chapters of this report and in the papers published over the past few years. The main discovery of this work was that surface topology plays a crucial role in the nucleation of diamond on silicon. Dennig and his collaborators demonstrated this by showing that diamond nucleates preferentially at the tips of asperities on a silicon surface rather than in the re-entrant comers at the base of such asperities. Some of the possible reasons for this effect are described in this report. The published papers listed on the next page of this report also describe this research. Interested persons can obtain copies of these papers from Professor Nix at Stanford. A full account of all of the research results obtained in this work is given in the regular chapters that follow this brief introduction. In addition, interested readers will want to consult Mr. Dennig`s Ph.D. dissertation when it is made available later this year.

  15. Final Technical Report - Advanced Optical Sensors to Minimize Energy Consumption in Polymer Extrusion Processes

    SciTech Connect

    Susan J. Foulk

    2012-07-24

    Project Objective: The objectives of this study are to develop an accurate and stable on-line sensor system to monitor color and composition on-line in polymer melts, to develop a scheme for using the output to control extruders to eliminate the energy, material and operational costs of off-specification product, and to combine or eliminate some extrusion processes. Background: Polymer extrusion processes are difficult to control because the quality achieved in the final product is complexly affected by the properties of the extruder screw, speed of extrusion, temperature, polymer composition, strength and dispersion properties of additives, and feeder system properties. Extruder systems are engineered to be highly reproducible so that when the correct settings to produce a particular product are found, that product can be reliably produced time after time. However market conditions often require changes in the final product, different products or grades may be processed in the same equipment, and feed materials vary from lot to lot. All of these changes require empirical adjustment of extruder settings to produce a product meeting specifications. Optical sensor systems that can continuously monitor the composition and color of the extruded polymer could detect process upsets, drift, blending oscillations, and changes in dispersion of additives. Development of an effective control algorithm using the output of the monitor would enable rapid corrections for changes in materials and operating conditions, thereby eliminating most of the scrap and recycle of current processing. This information could be used to identify extruder systems issues, diagnose problem sources, and suggest corrective actions in real-time to help keep extruder system settings within the optimum control region. Using these advanced optical sensor systems would give extruder operators real-time feedback from their process. They could reduce the amount of off-spec product produced and

    The economics of liquid-fuels production from microalgae was evaluated. A detailed review of published economic analyses of microalgae biomass production revealed wide variations in the published costs, which ranged from several dollars per pound for existing commercial health-food production in the Far East, to less than .05/lb costs projected for microalgae biomass for fuel conversion. As little design information or specific cost data has been published, a credible cost estimate required the conceptual engineering design and cost estimating of microalgae to liquid-fuels processes. Two systems were analyzed, shallow (2 to 3'') covered ponds and deeper (1 ft) open ponds. Only the latter was selected for an in-depth analysis due to the many technical shortcomings of the former approach. Based on the cost analysis of a very simple and low cost process, the most optimistic costs extrapolated were about $60/barrel. These were based on many optimistic assumptions. Additional, more detailed, engieering and cost analyses would be useful. However, the major emphasis in future work in this area should be on demonstrating the basic premises on which this design was based: high productivity and oil content of microalgae strains that can dominate in open ponds and which can be harvested by a simple bioflocculation process. Several specific basic research needs were identified: (1) Fundamentals of species selection and control in open pond systems. Effects of environmental variables on species dominance is of particular interest. (2) Mechanisms of algae bioflocculation. (3) Photosynthetic pathways and efficiency under conditions of high lipid production. (4) Effects of non-steady state operating conditions, particularly pH (CO/sub 2/ availability), on productivity. 18 figures, 47 tables.

    1981-01-01

    Based upon the analysis conducted for this study, the development of centralized ethanol conversion facilities in the Steuben and Allegany Counties is likely to be commercially feasible if either locally produced cheese whey and/or imported corn are used as feedstocks. Development is shown to be profitable under a broad range of potential economic conditions and technical considerations. Four plant designs varying in annual production capacity from 1.675 to 27.5 million gallons of ethanol (and utilizing alternative conversion technologies and feedstocks) are investigated. In general, all of the various plant sizes investigated are economically viable. Although economic profitability is enhanced by the existence of federal subsidies, in the form of $0.40 per gallon from federal gasoline tax rebates, energy investment tax credits and low interest loans, a public subsidy is not necessary, under most conditions, to ensure the economic feasibility of any of the plant design investigated. In all cases, a by-product in the form of an animal feed is produced, thereby generating additional revenue for the conversion facility and adding to the likelihood of commercial feasibility. In the case of the corn/whey plant, the by-product takes the form of a distillers dried grain. In the case of the whey plants, it takes the form of a high mineral, medium protein feed supplement for low and moderate producing dairy cattle. Both have a ready market in the study region. Fermenting of deproteinized whey to produce ethanol and drying the resulting distillation slops for animal feed completely utilizes the original cheese whey. The techniques developed in this study produce three valuable products and leave no residual requiring disposal.

    1996-04-30

    The project objective is to demonstrate removal of 90--95% or more of the SO{sub 2} at approximately one-half the cost of conventional scrubbing technology; and to demonstrate significant reduction of space requirements. In this project, Pure Air has built a single SO{sub 2} absorber for a 528-MWe power plant. The absorber performs three functions in a single vessel: prequencher, absorber, and oxidation of sludge to gypsum. Additionally, the absorber is of a co- current design, in which the flue gas and scrubbing slurry move in the same direction and at a relatively high velocity compared to conventional scrubbers. These features all combine to yield a state- of-the-art SO{sub 2} absorber that is more compact and less expensive than conventional scrubbers. The project incorporated a number of technical features including the injection of pulverized limestone directly into the absorber, a device called an air rotary sparger located within the base of the absorber, and a novel wastewater evaporation system. The air rotary sparger combines the functions of agitation and air distribution into one piece of equipment to facilitate the oxidation of calcium sulfite to gypsum. Additionally, wastewater treatment is being demonstrated to minimize water disposal problems inherent in many high-chloride coals. Bituminous coals primarily from the Indiana, Illinois coal basin containing 2--4.5% sulfur were tested during the demonstration. The Advanced Flue Gas Desulfurization (AFGD) process has demonstrated removal of 95% or more of the SO{sub 2} while providing a commercial gypsum by-product in lieu of solid waste. A portion of the commercial gypsum is being agglomerated into a product known as PowerChip{reg_sign} gypsum which exhibits improved physical properties, easier flowability and more user friendly handling characteristics to enhance its transportation and marketability to gypsum end-users.

    This report summarizes the work conducted under U.S. Department of Energy (US DOE) contract DE-FC36-04GO14286 by Chevron Technology Ventures (CTV, a division of Chevron U.S.A., Inc.), Hyundai Motor Company (HMC), and UTC Power (UTCP, a United Technologies company) to validate hydrogen (H2) infrastructure technology and fuel cell hybrid vehicles. Chevron established hydrogen filling stations at fleet operator sites using multiple technologies for on-site hydrogen generation, storage, and dispensing. CTV constructed five demonstration stations to support a vehicle fleet of 33 fuel cell passenger vehicles, eight internal combustion engine (ICE) vehicles, three fuel cell transit busses, and eight internal combustion engine shuttle busses. Stations were operated between 2005 and 2010. HMC introduced 33 fuel cell hybrid electric vehicles (FCHEV) in the course of the project. Generation I included 17 vehicles that used UTCP fuel cell power plants and operated at 350 bar. Generation II included 16 vehicles that had upgraded UTC fuel cell power plants and demonstrated options such as the use of super-capacitors and operation at 700 bar. All 33 vehicles used the Hyundai Tucson sports utility vehicle (SUV) platform. Fleet operators demonstrated commercial operation of the vehicles in three climate zones (hot, moderate, and cold) and for various driving patterns. Fleet operators were Southern California Edison (SCE), AC Transit (of Oakland, California), Hyundai America Technical Center Inc. (HATCI), and the U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC, in a site agreement with Selfridge Army National Guard Base in Selfridge, Michigan).

    SciTech Connect

    1996-05-01

    For radiation-instrument calibration to be generally acceptable throughout the US, direct or indirect traceability to a primary standard is required. In most instances, one of the primary standards established at NIST is employed for this purpose. The Department of Energy Laboratory Accreditation Program (DOELAP) is an example of a program employing dosimetry based on the NIST primary photon-, beta particle- and neutron-dosimetry standards. The NIST primary dosimetry standards for bremsstrahlung were first established in the 1950s. They have been updated since then on several occasions. In the 1970s, Technical Committee 85 of the International Standards Organization (ISO) started its work on establishing sets of internationally acceptable, well-characterized photon beams for the calibration of radiation-protection instruments. It is the intent of this paper to make a detailed comparison between the current NIST and the most up-to-date ISO techniques. At present, 41 bremsstrahlung techniques are specified in ISO 4037 while NIST supports a total of 32 techniques. Given the existing equivalences, it makes sense to try to extend the NIST techniques to cover more of the ISO Narrow Spectrum and High Air-Kerma Rate Series. These extensions will also allow the possibility for use of ISO beam techniques in future revisions of the DOELAP standard, which has been suggested by DOE. To this end, NIST was funded by DOE to procure material and make adaptations to the existing NIST x-ray calibration ranges to allow NIST to have the capability of producing all the ISO bremsstrahlung techniques. The following sections describe the steps that were taken to achieve this.

This project resulted in three commercially proven products and a marketing tool. The first was a Weather Research and Forecasting Model (WRF) based resource evaluation system. The second was a web-based service providing global 10m wind data from multiple sources to wind industry subscription customers. The third product addressed the needs of our utility clients looking at climate change effects on electricity distribution. For this we collaborated on the Santa Ana Wildfire Threat Index (SAWTi), which was released publicly last quarter. Finally to promote these products and educate potential users we released “Gust or Bust”, a graphic-novel styled marketing publication.

    For isolation of nuclear wastes through the vitrification process, waste slurry is mixed with borosilicate based glass and remelted at high temperature. During these processes, water can enter into the final waste glass. It is known that water in silica and silicate glasses changes various glass properties, such as chemical durability, viscosity and electrical conductivity. These properties are very important for processing and assuring the quality and safety controls of the waste glasses. The objective of this project was to investigate the effect of water in the simulated nuclear waste glasses on various glass properties, including chemical durability, glass transition temperature, liquidus temperature, viscosity and electrical conductivity. This report summarizes the results of this investigation conducted at Rensselaer during the past one year.

    The goal of this research was on the development of new, rapid, and efficient synthetic methods for incorporating short-lived radionuclides into agents of use in measuring dynamic processes. The initial project period (Year 1) was focused on the preparation of stable, solid state precursors that could be used to efficiently incorporate short-lived radioisotopes into small molecules of use in biological applications (environmental, plant, and animal). The investigation included development and evaluation of new methods for preparing carbon-carbon and carbon-halogen bonds for use in constructing the substrates to be radiolabeled. The second phase (Year 2) was focused on developing isotope incorporation techniques using the stable, boronated polymeric precursors. The final phase (Year 3), was focused on the preparation of specific radiolabeled agents and evaluation of their biodistribution using micro-PET and micro-SPECT. In addition, we began the development of a new series of polymeric borane reagents based on polyethylene glycol backbones.

    The design of an advanced Stirling engine is considered for potential use in Air Force mobile electric power generator sets. The prospects for acceptable reliability appears good due to new approaches to recognized Stirling problem areas; sealing, heater head and control. The present design appears suitable for a 30kW set, but Air Force needs would be best suited by development of a 60kW unit. Standardization would be facilitated by using the 60kW Stirling engine and associated auxiliaries in a 30kW set. Final design drawings have been completed in the 30kW engine but construction and tests are required to establish that both design criteria for the engine and mobile power requirements are met. Originator-supplied keywords include: Heat pipe, and Combustor control.

The effects of produced water (PW) was assessed on development in three ecologically and economically important species, the purple sea urchin (Strongylocentrotus purpuratus), the giant kelp (macrocystis pyrifera), and tsahe California mussel (Mytilus califonrnianus). To determine the basis for effects of PW on these developing organisms, some fundamental studies were prerequisite. Furthermore, eggs and embryos from adults which were outplanted near the discharge were also studied. Finally, the biochemical response of embryos to PW was also defined.

This final report summarizes research efforts in the following areas: electrons in biological systems; and electron and ion transport and reactions in model liquids. In biological systems attention was focused on the following: excess electrons as probes of carcinogen electrophilicity; cost effectiveness of k{sub e} as a carcinogen-screening test; and conversion of k{sub e} to a carcinogen-screening electronic device. In model liquids, research was focused on two areas. The first investigated radiation-induced dimerization of fullerenes. The second area studied radiolytic synthesis of fullerene derivatives.

    2001-03-26

    This item constitutes the final report on ''Visionics: An integrated approach to analysis and design of intelligent machines.'' The report discusses dynamical systems approach to problems in robust control of possibly time-varying linear systems, problems in vision and visually guided control, and, finally, applications of these control techniques to intelligent navigation with a mobile platform. Robust design of a controller for a time-varying system essentially deals with the problem of synthesizing a controller that can adapt to sudden changes in the parameters of the plant and can maintain stability. The approach presented is to design a compensator that simultaneously stabilizes each and every possible mode of the plant as the parameters undergo sudden and unexpected changes. Such changes can in fact be detected by a visual sensor and, hence, visually guided control problems are studied as a natural consequence. The problem here is to detect parameters of the plant and maintain st ability in the closed loop using a ccd camera as a sensor. The main result discussed in the report is the role of perspective systems theory that was developed in order to analyze such a detection and control problem. The robust control algorithms and the visually guided control algorithms are applied in the context of a PUMA 560 robot arm control where the goal is to visually locate a moving part on a mobile turntable. Such problems are of paramount importance in manufacturing with a certain lack of structure. Sensor guided control problems are extended to problems in robot navigation using a NOMADIC mobile platform with a ccd and a laser range finder as sensors. The localization and map building problems are studied with the objective of navigation in an unstructured terrain.

    A component of the landing site selection process for the Mars Science Laboratory (MSL) involved the presence of phyllosilicates as the main astrobiological targets. Gale crater was selected as the MSL landing site from among 4 down selected study sites (Gale, Eberswalde and Holden craters, Mawrth Vallis) that addressed the primary scientific goal of assessing the past habitability of Mars. A key constraint on the formation process of these phyllosilicate-bearing deposits is in the precise mineralogical composition. We present a reassessment of the mineralogy of the sites combined with a determination of the modal mineralogy of the major phyllosilicate-bearing deposits of the four final study sites from the modeling of near-infrared spectra using a radiative transfer model. The largest abundance of phyllosilicates (30-70%) is found in Mawrth Vallis, the lowest one in Eberswalde (<25%). Except for Mawrth Vallis, the anhydrous phases (plagioclase, pyroxenes and martian dust) are the dominant phases, suggesting formation conditions with a lower alteration grade and/or a post-formation mixing with anhydrous phases. The composition of Holden layered deposits (mixture of saponite and micas with a total abundance in the range of 25-45%) suggests transport and deposition of altered basalts of the Noachian crust without major chemical transformation. For Eberswalde, the modal mineralogy is also consistent with detrital clays, but the presence of opaline silica indicates that an authigenic formation occurred during the deposition. The overall composition including approximately 20-30% smectite detected by MSL in the rocks of Yellow-knife Bay area interpreted to be material deposited on the floor of Gale crater by channels (http://www.nasa.gov/mission_pages/msl/news/msl20130312.html) is consistent with the compositions modeled for the Eberswalde and Holden deltaic rocks. At Gale, the paucity, the small diversity and the low abundance of nontronite do not favor a complex and

    During the past decade, endogenous antimicrobial peptides have become recognized as important, ubiquitous, and ancient contributors to the innate mechanisms which permit animals (including humans), and plants to resist infection. Most of these host defense peptides are small (18-35 amino acids), amphipathic and possess either an {alpha}-helical or cystine-stabilized {beta}-sheet structure. These peptides are probably too small for enzymatic function and, so far, no specific receptors have been found. All evidence indicates that their target of action is the lipid matrix of the bacterial cytoplasmic membranes. This project aimed at clarifying the mechanism of peptide-membrane interactions, in particular the pore formation by the peptides which appear to be the mode of action of these antimicrobials. Tremendous progress was made during the project period. We summarize our findings in the following report.

The specific aims were: (1) to characterize the mechanism of acetyl-CoA conversion to CH{sub 3}-H{sub 4}MPT, CO, and CoA and elucidate the mechanism of CO oxidation by the methanosarcina thermophila CO dehydrogenase/acetyl-CoA synthase (CODH/ACS), and (2) to study the mechanism of methyl-CoM reduction to methane by developing an activation protocol for methyl-CoM reductase (MCR) and identifying intermediates in the MCR mechanism. The authors also made significant progress toward accomplishing two other specific aims that were not included in the original proposal. These were: (1) to characterize the M. thermophila heterodisulfide reductase (HDR), and (2) to characterize the methyltetrahydromethanopterin: Coenzyme M methyltransferase from Methanosarcina mazei strain Goe1 in collaboration with Gerhard Gottschalk`s group. Results from these four studies are summarized.

    This report summarizes the results of low-temperature geothermal energy resource assessment efforts in New Mexico during the period from June 15, 1981 through September 30, 1983, under the sponsorship of the US Department of Energy (Contract DE-AS07-78ID01717). The report is divided into four chapters which correspond to the tasks delineated in the contract. Chapter 5 is a brief summary of the tasks performed under this contract during the period October 1, 1978, through June 30, 1983. This work extends the knowledge of low-temperature geothermal reservoirs with the potential for direct heating applications in New Mexico. The research effort focused on compiling basic geothermal data throughout selected areas in New Mexico in a format suitable for direct transfer to the US Geological Survey for inclusion in the GEOTHERM data file and to the National Oceanic and Atmospheric Administration for use with New Mexico geothermal resources maps.

    Correa, S.M.

    The three issues of NOx, CO/UHC and dynamics were studied. First, NOx was measured in lean premixed methane combustion stabilized over a 5 cm dia. perforated-plate burner in the range 3-10 atm, inlet temperature 300-615K (80-647 F), and fuel-air equivalence ratio 0.5 - 0.8. Experimental data compared to within 50% with predictions of a stirred/plug-flow reactor model. For flames below about 1750K (2690 F), (i) NOx formation rates in post-flame gas are < 1 ppm/ms, so combustors can be lengthened to burn out CO and unburned hydrocarbons without increasing NOx and (ii) NOx formation becomes slow enough to decouple from the turbulence, so the flameholder shape can be optimized based on CO and dynamics. Second, analyses suggest that CO quenching effects are generally too small to be significant but (i) CO can be quenched in stagnation point flow of post-flame gas towards the combustor wall, (ii) CO can be quenched in turbulent eddies if unburned fuel-air premixture escapes the flame zone and pyrolyzes downstream in cooler flow, and (iii) the acoustic interaction can exacerbate CO emissions in those cases where the base CO is high (e.g., 10-100 times equilibrium levels) and the pressure fluctuations are large (e.g., 5-10% peak-to-peak). Except in these extreme cases, however, CO/UHC emissions should not be a limiting factor in the use of lean premixed combustion to minimize NOx. Last, Discrete Vortex calculations were compared with data from a 13.5 cm (5.3 in.) burner at lean conditions approaching blowoff. Strouhal shedding frequencies were detected, suggesting a role for flameholder-shed vorticity.

    This Concept Definition Study focused on developing a scientific understanding of methods to reduce energy consumption in data networks using rate adaptation. Rate adaptation is a collection of techniques that reduce energy consumption when traffic is light, and only require full energy when traffic is at full provisioned capacity. Rate adaptation is a very promising technique for saving energy: modern data networks are typically operated at average rates well below capacity, but network equipment has not yet been designed to incorporate rate adaptation. The Study concerns packet-switching equipment, routers and switches; such equipment forms the backbone of the modern Internet. The focus of the study is on algorithms and protocols that can be implemented in software or firmware to exploit hardware power-control mechanisms. Hardware power-control mechanisms are widely used in the computer industry, and are beginning to be available for networking equipment as well. Network equipment has different performance requirements than computer equipment because of the very fast rate of packet arrival; hence novel power-control algorithms are required for networking. This study resulted in five published papers, one internal report, and two patent applications, documented below. The specific technical accomplishments are the following: • A model for the power consumption of switching equipment used in service-provider telecommunication networks as a function of operating state, and measured power-consumption values for typical current equipment. • An algorithm for use in a router that adapts packet processing rate and hence power consumption to traffic load while maintaining performance guarantees on delay and throughput. • An algorithm that performs network-wide traffic routing with the objective of minimizing energy consumption, assuming that routers have less-than-ideal rate adaptivity. • An estimate of the potential energy savings in service-provider networks

    The purpose of this project is to develop a long shafted pump to operate at high temperatures for the purpose of producing energy with renewable resources. In Phase I of this three phase project we developed molten salt pump requirements, evaluated existing hardware designs for necessary modifications, developed a preliminary design of the pump concept, and developed refined cost estimates for Phase II and Phase III of the project. The decision has been made not to continue the project into Phases II and III. There is an ever increasing world-wide demand for sources of energy. With only a limited supply of fossil fuels, and with the costs to obtain and produce those fuels increasing, sources of renewable energy must be found. Currently, capturing the sun's energy is expensive compared to heritage fossil fuel energy production. However, there are government requirements on Industry to increase the amount of energy generated from renewable resources. The objective of this project is to design, build and test a long-shafted, molten salt pump. This is the type of pump necessary for a molten salt thermal storage system in a commercial-scale solar trough plant. This project is under the Department of Energy (DOE) Solar Energy Technologies Program, managed by the Office of Energy Efficiency and Renewable Energy. To reduce the levelized cost of energy (LCOE), and to meet the requirements of 'tomorrows' demand, technical innovations are needed. The DOE is committed to reducing the LCOE to 7-10 cents/kWh by 2015, and to 5-7 cents/kWh by 2020. To accomplish these goals, the performance envelope for commercial use of long-shafted molten salt pumps must be expanded. The intent of this project is to verify acceptable operation of pump components in the type of molten salt (thermal storage medium) used in commercial power plants today. Field testing will be necessary to verify the integrity of the pump design, and thus reduce the risk to industry. While the primary goal is to

    The Ocean Thermal Energy Conversion (OTEC) Life Cycle Cost Assessment (OLCCA) is a study performed by members of the Lockheed Martin (LM) OTEC Team under funding from the Department of Energy (DOE), Award No. DE-EE0002663, dated 01/01/2010. OLCCA objectives are to estimate procurement, operations and maintenance, and overhaul costs for two types of OTEC plants: -Plants moored to the sea floor where the electricity produced by the OTEC plant is directly connected to the grid ashore via a marine power cable (Grid Connected OTEC plants) -Open-ocean grazing OTEC plant-ships producing an energy carrier that is transported to designated ports (Energy Carrier OTEC plants) Costs are developed using the concept of levelized cost of energy established by DOE for use in comparing electricity costs from various generating systems. One area of system costs that had not been developed in detail prior to this analysis was the operations and sustainment (O&S) cost for both types of OTEC plants. Procurement costs, generally referred to as capital expense and O&S costs (operations and maintenance (O&M) costs plus overhaul and replacement costs), are assessed over the 30 year operational life of the plants and an annual annuity calculated to achieve a levelized cost (constant across entire plant life). Dividing this levelized cost by the average annual energy production results in a levelized cost of electricity, or LCOE, for the OTEC plants. Technical and production efficiency enhancements that could result in a lower value of the OTEC LCOE were also explored. The thermal OTEC resource for Oahu, Hawaii and projected build out plan were developed. The estimate of the OTEC resource and LCOE values for the planned OTEC systems enable this information to be displayed as energy supplied versus levelized cost of the supplied energy; this curve is referred to as an Energy Supply Curve. The Oahu Energy Supply Curve represents initial OTEC deployment starting in 2018 and demonstrates the

    This document is the final report for DOE grant number DE-FG02-02ER63472: "The impact of enhanced nitrogen fixation on carbon sequestration: a reassessment of the inorganic carbon system in LNLC regions" to Patricia L. Yager at the University of Georgia School of Marine Programs. This project examined the inorganic carbon system associated with nitrogen fixation in the “low nutrient low chlorophyll” (LNLC) regions of the western tropical North Atlantic (WTNA) and subtropical Pacific Oceans. Total dissolved inorganic carbon (DIC) and alkalinity (ALK) data were measured on seven expeditions. Data have been finalized, checked for quality assurance, and uploaded to the Carbon Dioxide Information Analysis Center website (http://cdiac.ornl.gov/). Two manuscripts using this data are published or in press so far and we are current working on two others. The first (Cooley and Yager, 2006, JGR) uses a mixing model to remove the dilution effects of the Amazon River from the WTNA inorganic carbon data set. Once the physical effect is removed, the paper then estimates net community production (NCP) for each station. Enhanced rates of production (over respiration) are seen in the river plume, establishing a large biogenic atmospheric carbon sink in this region that is otherwise a source of carbon to the atmosphere. We note that this sink occurs in the absence of a measurable nitrate flux, and correlates well with the abundance of diatoms containing endosymbiotic diazotrophs, so it must be supported by nitrogen fixation. The second manuscript (Cooley et al., in press, GBC) compares our WTNA data (from Winter 2001, Spring 2001, and Summer 2003) to previously collected datasets (Ternon et al. 2000, Kortzinger et al. 2003) for the purposes of identifying seasonal and interannual variability in Amazon River-associated carbon sequestration. For the mid-salinity regions of the plume only, we estimate a carbon sink of 15±6 TgC per year. This is a globally significant flux that also

    In order to develop an effective hydrazine remediation technique, the environmental fate and transport of its breakdown products must be identified and quantified. Hydrazine and methyl hydrazine auto-oxidation were studied in the presence of colloidial hematite, a common soil mineral. It was found that auto-ozidation in the presence of the hematite was attenuated when compared to auto-ozidation in water only. This indicates that the interaction between the hydrazines and the hematite in some way protects the hydrazines. The specific interaction between the hydrazines and hematite was investigated using fourier transform infrared spectroscopy using attenuated total reflectance sampling (FTIR-ATR) enabling direct spectral analysis of the interaction without the interference of chemical diluents such as potassium bromide, which are used in more common FTIR methods. These analyses indicated that the interaction is probably due to electrostatic interactions, including hydrogen bonding between the hydrazines and the oxygens, or the first hydration spheres, on the hematite. It was found that the interaction changes with time, and that the interaction is stable to heating, and appear to have a long lifetime, indicating a strong final interaction. Similar results were found when the FTIR-ATR was also used to analyze the interaction of the hydrazines with common clay minerals.

    The Commercial Buildings Consortium (CBC) was established in 2009, under the chairmanship of the National Association of State Energy Officials (NASEO), as a supporting organization to the Commercial Buildings Initiative (CBI). The CBI was created by Congress through the Energy Independence and Security Act of 2007 (EISA) and launched by the Department of Energy (DOE) in 2008 with the goal to “develop and disseminate technologies, practices, and policies for establishment of zero net energy commercial buildings.”. The impact of the CBC since 2009 has been multifold, resulting in increased collaboration, increased innovation, and increased demonstration and deployment. During the project performance period of 2009-2014, the CBC provided an organizational framework for sustained public-private collaboration among more than 600 commercial building professionals, researchers and educators, utilities, and government agencies at federal, state, and local level. The CBC’s research has identified emerging technologies, market strategies, and innovative public and corporate policies to help advance CBI’s zero-net-energy. Finally, the CBC worked in close partnership with DOE’s commercial building teams and the Better Buildings Alliances to identify opportunities for proving out and deploying energy-saving technologies and practices.

    Several kinds of electron paramagnetic resonance (EPR) spectra of coal (including whole coal, separated macerals, density-gradient separated fractions, and treated coals) and of model organic thought to be molecular constituents of coals were acquired and analyzed in order to probe the molecular structure and surface properties of coals and of model systems. Typically, the model compounds under investigation and their analogues are found in coals as stable free radicals which give rise to an EPR signal. In some cases, the model compounds were selected because they have some characteristic, such as a particular functional group or heteroatom which may be found in coals, which fits them to serve as test materials for methods development. Two critical instruments for this work - the W-band EPR spectrometer and the S-band ESE spectrometer - were built in this laboratory and were both further developed as part of this project. The ENDOR spectrometer also has been improved. During the course of this project, the W-band EPR system has proven to be the most fruitful tool for probing the chemical structures of coal with the ESE system providing the most valuable auxiliary data. The following report summarizes highlights of these studies. It provides some background, rationale, and selected data and results. Finally, a list of papers and presentations is provided together with abstracts of all of them.

    The Strategic Environmental Research and Development Program (SERDP) issued a statement of need for FY01 titled Statistical Sampling for Unexploded Ordnance (UXO) Site Characterization that solicited proposals to develop statistically valid sampling protocols for cost-effective, practical, and reliable investigation of sites contaminated with UXO; protocols that could be validated through subsequent field demonstrations. The SERDP goal was the development of a sampling strategy for which a fraction of the site is initially surveyed by geophysical detectors to confidently identify clean areas and subsections (target areas, TAs) that had elevated densities of anomalous geophysical detector readings that could indicate the presence of UXO. More detailed surveys could then be conducted to search the identified TAs for UXO. SERDP funded three projects: those proposed by the Pacific Northwest National Laboratory (PNNL) (SERDP Project No. UXO 1199), Sandia National Laboratory (SNL), and Oak Ridge National Laboratory (ORNL). The projects were closely coordinated to minimize duplication of effort and facilitate use of shared algorithms where feasible. This final report for PNNL Project 1199 describes the methods developed by PNNL to address SERDP's statement-of-need for the development of statistically-based geophysical survey methods for sites where 100% surveys are unattainable or cost prohibitive.

    The theoretical part of this investigation has achieved its objective. By means of the Monte Carlo simulation the Knudsen diffusion of gases in ''Swiss cheese'' solid has been studied and shown to yield results similar to studies on the ''cannonball'' solids that were the subject of a prior investigation at Berkeley. A correlation was developed that permits a prediction of the Knudsen diffusion coefficient of any gas in any porous solid with a monodisperse pore size distribution. The Monte Carlo technique has also been used to simulate ordinary diffusion in porous solids of both Swiss cheese and cannonball types, and a predictive correlation developed for this regime also. An unanticipated result of this study was the recognition of the analogy between diffusion of a gas in a porous solid and other transport phenomena in heterogeneous media. The Berkeley investigation has drawn together data from the Monte Carlo simulation, empirical predictive equations from the diffusion literature and classical results from theoretical physics on conduction in hetergeneous media. Finally the Monte Carlo technique was extended to porous solids with a bidisperse pore structure and it was again shown that the results are consistent with expectations. The experimental phase of this investigation has been successful in measuring the viscosites and diffusivities of a number of gases over a wide range of temperature of practical interest. The experimental results have been in agreement with the experimental data of others (mostly at lower temperature) and with theoretical predictions, in most instances. 17 refs., 26 figs.

    The objective of this research project was to develop a second generation duct sorbent injection technology as a cost-effective compliance option for the 1990 Clean Air Act Amendments. Research and development work was focused on the Advanced Coolside process, which showed the potential for exceeding the original performance targets of 90% SO{sub 2} removal and 60% sorbent utilization. Process development was conducted in a 1000 acfm pilot plant. The pilot plant testing showed that the Advanced Coolside process can achieve 90% SO{sub 2} removal at sorbent utilizations up to 75%. The testing also showed that the process has the potential to achieve very high removal efficiency (90 to >99%). By conducting conceptual process design and economic evaluations periodically during the project, development work was focused on process design improvements which substantially lowered process capital and operating costs, A final process economic study projects capital costs less than one half of those for limestone forced oxidation wet FGD. Projected total SO{sub 2} control cost is about 25% lower than wet FGD for a 260 MWe plant burning a 2.5% sulfur coal. A waste management study showed the acceptability of landfill disposal; it also identified a potential avenue for by-product utilization which should be further investigated. Based on the pilot plant performance and on the above economic projections, future work to scale up the Advanced Coolside process is recommended.

    This final report presents the results of research into two important areas of concern for fault-tolerant avionics systems: testability analysis and innovative repair policies. The algorithms developed from this research have been included in the Mission Reliability Model (MIREM) and verified by comparison with known results from several Integrated Communication, Navigation, and Identification Avionics architectures. The purpose of the testability analysis was to develop techniques for assessing the impact of imperfect switching on the overall reliability of fault-tolerant avionics. A method of quantifying the effects of undetected errors and false alarms has been developed and included in MIREM. Under the next phase of the program, three repair statistics were identified: Mean Time To Repair, Mean Time Between Maintenance Actions, and Inherent Availability. These were used to define four alternative repair policies: immediate repair, deferred repair, scheduled maintenance, and repair at degraded level. Also included in MIREM as model outputs, these four options offer greater flexibility in evaluating and developing avionics designs.

    The 1961-1990 National Solar Radiation Data Base (NSRDB) for the United States was completed in September 1992. This was the final product of four years of work under the U.S. Department of Energy (DOE) Solar Radiation Resource Assessment Project. The NSRDB contains 30 years of hourly data for five solar radiation elements and 15 meteorological elements for 239 sites. The user`s manual (NSRDB-Volume 1, 1992) for the NSRDB provides detailed information on the structure of the data base and the products that have been produced from it. Most users of the data base will find all of the information that they need in Volume 1. Volume 2 has been written primarily for researchers who need more information about the methods employed in producing the data base. In addition to research results, we have included information on practical lessons learned from this project. Therefore, Volume 2 should be of value to anyone developing a similar data base for other regions or other countries. Most of the solar radiation data in the NSRDB and the previous SOLMET (SOLar METeorological) data base were generated by computer models. Therefore, a major part of this report is centered around the METeorological/STATistical (METSTAT) model (Section 3.0), its input data (Sections 5.0 and 6.0), its use in producing the NSRDB (Sections 4.0 and 7.0), and comparisons with the models used in producing the SOLMET data base (Section 10.0).

Amorphous silicon is chosen as the PV technology that Chronar Corporation and APS believe offers the greatest potential for manufacturing improvements, which, in turn, will result in significant cost reductions and performance improvements in photovoltaic products. The APS ``Eureka`` facility was chosen as the manufacturing system that can offer the possibility of achieving these production enhancements. The relationship of the ``Eureka`` facility to Chronar`s ``batch`` plants is discussed. Five key areas are also identified that could meet the objectives of manufacturing potential that could lead to improved performance, reduced manufacturing costs, and significantly increased production. The projected long-term potential benefits of these areas are discussed, as well as problems that may impede the achievement of the hoped-for developments. A significant number of the problems discussed are of a generic nature and could be of general interest to the industry. The final section of this document addresses the cost and time estimates for achieving the solutions to the problems discussed earlier. Emphasis is placed on the number, type, and cost of the human resources required for the project.

    Addition of phenol recovery to the wastewater treatment scheme in the Baseline Design for the SRC-I Demonstration Plant was evaluated as a major post-Baseline effort. Phenol recovery affects many downstream processes, but this study was designed to assess primarily its effects on biooxidation and subsequent tertiary treatment. Two parallel treatment schemes were set up, one to treat dephenolated wastewaters and the other for processed nondephenolated wastewaters, a simulation of the Baseline Design. The study focused on comparisons of five areas: effluent quality; system stability; the need for continuous, high-dose powdered activated carbon (PAC) augmentation to the bioreactor; minimum bioreactor hydraulic residence time (HRT); and tertiary treatment requirements. The results show that phenol recovery improves the quality of the bioreactor effluent in terms of residual organics and color. With phenol recovery, PAC augmentation is not required; without phenol recovery, PAC is needed to produce a comparable effluent. Dephenolization also enhances the stability of biooxidation, and reduces the minimum HRT required. With tertiary treatment, both schemes can meet the effluent concentrations published in the SRC-I Final Envivornmental Impact Statement, as well as the anticipated effluent limits. However, phenol recovery does provide a wider safety margin and could eliminate the need for some of the tertiary treatment steps. Based solely on the technical merits observed in this study, phenol recovery is recommended. The final selection should, however, also consider economic tradeoffs and results of other studies such as toxicology testing of the effluents. 34 references, 30 figures and 26 tables.

    The Emigrant Slimhole Drilling Project (ESDP) was a highly successful, phased resource evaluation program designed to evaluate the commercial geothermal potential of the eastern margin of the northern Fish Lake Valley pull-apart basin in west-central Nevada. The program involved three phases: (1) Resource evaluation; (2) Drilling and resource characterization; and (3) Resource testing and assessment. Efforts included detailed geologic mapping; 3-D modeling; compilation of a GIS database; and production of a conceptual geologic model followed by the successful drilling of the 2,938 foot deep 17-31 slimhole (core hole), which encountered commercial geothermal temperatures (327⁰ F) and exhibits an increasing, conductive, temperature gradient to total depth; completion of a short injection test; and compilation of a detailed geologic core log and revised geologic cross-sections. Results of the project greatly increased the understanding of the geologic model controlling the Emigrant geothermal resource. Information gained from the 17-31 core hole revealed the existence of commercial temperatures beneath the area in the Silver Peak Core Complex which is composed of formations that exhibit excellent reservoir characteristics. Knowledge gained from the ESDP may lead to the development of a new commercial geothermal field in Nevada. Completion of the 17-31 core hole also demonstrated the cost-effectiveness of deep core drilling as an exploration tool and the unequaled value of core in understanding the geology, mineralogy, evolutional history and structural aspects of a geothermal resource.

    The principal objective of the study is to seek an understanding of the processes involved in the transformation of ligno-cellulosic cell walls of higher plants into coal-forming entities during the early stages of coal formation. It is felt that this is one valid and potentially valuable approach to solving the problems of coal structure and elucidating the origins of coal macerals. The tactical approach has been to select samples of very immature coals that exhibit differing degrees of preservation of woody structure and examine them by optical microscopy, using transmission of light through thin sections with and without polarizing screens, and fluorescence excited by blue or uv light. Specimens characterized in this way were then studied by Fourier Transform Infrared spectroscopy, /sup 13/C NMR and various pyrolysis/mass spectrometric techniques. Samples from two different sites were available, but most of the work was on a large set of samples collected from the Brandon lignite in Vermont; plants whose remains are seen in this lignite include many of those now populating parts of the Okefenokee Swamp in Georgia and the Everglades of Florida. A number of samples of peatified wood were included in the microscopic studies, in order to document the earliest changes and provide material for comparison.

    The properties of optically-excited Hg/NH/sub 3/ and Hg/ND/sub 3/ mixtures have been studied as a function of mercury pressure in the range 1 to 40 torr. At low mercury pressures, less than or equal to 1 torr, the well-known uv emission band due to HgNH/sub 3/* is dominant; this regime has been investigated extensively over the past ten years. However, at higher pressures the uv band disappears and is replaced by a strong green emission band, centered near 500 nm. From a detailed study of the spectral and temporal characteristics of the green band, it is concluded that it arises from the formation of the Hg/sub 2/NH/sub 3/* (or Hg/sub 2/ND/sub 3/*) excited molecular complex. The lifetime of this exciplex has been measured and is found to be 3.8 ..mu..sec (+- 25%). Because of interest in the system as a potential energy storage laser medium, optical transmission measurements have been carried out at selected wavelengths. Net absorption has been observed across the green band at high mercury density, as well as in the uv band in the low density regime.

    The purpose of this grant was to bring together the principals of all known facilities that had been developed, principals who had submitted proposals to develop FACE facilities, and principals who want to develop proposals for facilities. In addition, critical program personnel from potential funding agencies and a few high level science administrators were invited to observe the proceedings and to visit a working FACE facility. The objectives of this study are to conduct a three-day international meeting on scientific aspects of research with the new and developing free air carbon enrichment (FACE) technology. Immediately following the science meeting, conduct a two-day international meeting on experimental protocols to be applied in FACE research. To conduct a four day international meeting on the assessment of the responses of forest ecosystems to elevated atmospheric carbon dioxide. The three meetings supported by this grant were all highly successful meetings and resulted in the formation of an organized and identified working group with the acronym InterFACE (International Free-Air Carbon Dioxide Enrichment) working group.

    Objective is to study the static fatigue mechanism of silica glasses such as optical communication fibers. It is shown that the strength increase by thermal or hydrothermal treatment can be explained by formation of blunt crack tips. Specimens with blunt cracks exhibited fatigue only in water and NH3. While fatigue of glasses with sharp cracks involves only crack propagation, that of glasses with blunt cracks involves both crack initiation and propagation. Nonaqueous liquids can be adsorbed on the glass surface only, thus can aid crack propagation only. Water/NH3 can exhibit both adsorption and diffusion, and the ability of water to initiate a crack appears related to its diffusion into the glass. Mechanical fatigue of pristine silica fibers takes place in water but is not expected in nonaqueous liquids. Water entry into silica glass is accelerated by applied stress. Water entry (diffusion) into silica glasses at low temperatures was found closely coupled with structural relaxation of the glass, which lowers the fictive temperature. The relaxation can be monitored by simple IR spectroscopy; IR absorbance measures the fictive temperature over the entire thickness while IR reflection measures that of the surface. By combining IR reflection peak position measurement and successive etching, the depth profile of the fictive temperature can be determined. This was done in a communication fiber and in a specimen heat treated below the glass transition temperature. Glasses with higher fictive temperatures exhibit greater fatigue resistance.

    The first and second prototype downhole pneumatic turbine motors have been fabricated, assembled and tested. All bench tests showed that the motor will produce horsepower and bit speeds approximating the predicted values. Specifically, the downhole pneumatic turbine motor produced approximately 50 horsepower at 100 rpm, while being supplied with about 3600 SCFM of compressed air. The first prototype was used in a drilling test from a depth of 389 feet to a depth of 789 feet in the Kirtland formation. This first prototype motor drilled at a rate exceeding 180 ft/hr, utilizing only 3000 SCFM of compressed air. High temperature tests (at approximately 460/sup 0/F) were carried out on the thrust assembly and the gearboxes for the two prototypes. These components operated successfully at these temperatures. Although the bench and drilling tests were successful, the tests revealed design changes that should be made before drilling tests are carried out in geothermal boreholes at the Geysers area, near Santa Rosa, California.

    This grant was in effect for a quite long time: 1984-2008. This period saw a broad range of research activities transpire in my group, and these enlisted the participation of many students, postdoctorals, and visitors. The earliest participants have since enjoyed full careers: faculty members here and abroad, government laboratories, successful entrepreneurs, and so on. Some have even retired! Consequently, during the past few months I have repeatedly asked myself: how can a coherent, readable report be prepared that covers so long a period of time and so varied a collection of projects? On the one hand, the work has evolved — a sensible progression of experimental techniques and strategies, as well as a parallel deepening of our theoretical understanding. On the other hand, there is a distinctive¬ness to many of the projects that enables them to be arranged into groups. In the end a compromise was struck. Areas and topics that received the most focused attention are identified. Our main contributions and how they relate to the field of chemical dynamics, in general, are organized according to these groups. Publications are listed but not explained per se, as this would produce a manifestly unreadable document. They are all available in PDF format upon request. Following this, brief synopses are presented for each of the groupings — getting straight to the point, but with the wisdom of hindsight.

    -efficiency CIGS and a-Si:H with operating features compatible with high-efficiency photoelectrochemical (PEC) water-splitting. The objective of one activity under the hydrogen production from biomass task was to conduct parametric testing of the Pearson gasifier and to determine the effects of gasifier operating conditions on the gas yields and quality. The hydrogen yield from this gasifier was evaluated in a parametric test series over a range of residence times from 0.8 to 2.2 seconds. H2 concentrations as high as 55% (volume) were measured in the product gas at the longer residence times and this corresponds to a hydrogen yield of 90 kg per tonne of bagasse without gas upgrading. The objective of another activity was to develop hot gas clean-up capabilities for the HNEI gasifier test facility to support hydrogen-from-biomass research. The product gas stream at the outlet of the hot gas filter was characterized for concentrations of permanent gas species and contaminants. Biomass feedstock processing activity included a preliminary investigation into methods for processing sugar cane trash at the Puunene Sugar Factory on the island of Maui, Hawaii. The objective of the investigation was to explore treatment methods that would enable the successful use of cane trash as fuel for the production of hydrogen via gasification. Analyses were completed for the technical and economic feasibility of producing biofuel from photosynthetic marine microbes on a commercial scale. Results included estimates for total costs, energy efficiency, and return on investment. The biohydrogen team undertook a comprehensive review of the field and came to what is considered a realistic conclusion. To summarize, continued research is recommended in the fundamentals of the science related to genetic engineering and specific topics to cover knowledge gaps. In the meantime, the team also advocates continued development of related processes which can be linked to pollution control and other real world

    Conventional drilling methods are very mature, but still have difficulty drilling through very deep,very hard and hot rocks for geothermal, nuclear waste entombment and oil and gas applications.This project demonstrated the capabilities of utilizing only high energy beams to drill such rocks,commonly called ‘Direct Energy Drilling’, which has been the dream of industry since the invention of the laser in the 1960s. A new region of the electromagnetic spectrum, millimeter wave (MMW) wavelengths at 30-300 giga-hertz (GHz) frequency was used to accomplish this feat. To demonstrate MMW beam drilling capabilities a lab bench waveguide delivery, monitoring and instrument system was designed, built and tested around an existing (but non-optimal) 28 GHz frequency, 10 kilowatt (kW) gyrotron. Low waveguide efficiency, plasma generation and reflected power challenges were overcome. Real-time monitoring of the drilling process was also demonstrated. Then the technical capability of using only high power intense millimeter waves to melt (with some vaporization) four different rock types (granite, basalt, sandstone, limestone) was demonstrated through 36 bench tests. Full bore drilling up to 2” diameter (size limited by the available MMW power) was demonstrated through granite and basalt samples. The project also demonstrated that MMW beam transmission losses through high temperature (260°C, 500oF), high pressure (34.5 MPa, 5000 psi) nitrogen gas was below the error range of the meter long path length test equipment and instruments utilized. To refine those transmission losses closer, to allow extrapolation to very great distances, will require a new test cell design and higher sensitivity instruments. All rock samples subjected to high peak temperature by MMW beams developed fractures due to thermal stresses, although the peak temperature was thermodynamically limited by radiative losses. Therefore, this limited drill rate and rock strength data were not able to be

    The Industrial Assessment Center (IAC) program at West Virginia University (WVU), which is funded by the Industrial Technologies Program (ITP) in the U.S. Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy (EERE), has provided a unique opportunity to enhance efficient energy utilization in small to medium-sized manufacturers. It has also provided training to engineering students in the identification and analysis of efficient energy use in each aspect of the manufacturing process and associated supporting elements. The outcomes of the IAC Program at WVU have assisted the manufacturers and the students in having a heightened sensitivity to industrial energy conservation, waste reduction, and productivity improvement, as well as a better understanding of the technical aspects of manufacturing processes and the supporting elements through which efficient energy utilization can be enhanced. The IAC at WVU has conducted 101 energy assessments from 2002 until 2006. The focus of the industrial assessments has been on energy savings. It has been the IAC’s interest to strongly focus on energy savings and on waste minimization and productivity improvements that strictly have an impact on energy. The IAC at WVU was selected as the Center of the year in 2005 from amongst 26 centers and has obtained a ranking within the top 5 in the previous few years. From 2002 to 2006, the total recommended energy savings produced by the IAC at WVU is 1,214,414 MMBtu, of which the electricity accounts for 93,826,067 kWh (equivalent to 320,226 MMBtu) and natural gas for 871,743 MMBtu. The balance is accounted for in savings in other fuels, mainly coal and wood. This results in an average recommended energy savings of 928,971 kWh from electricity and 8,631 MMBtu from natural gas per facility. The total CO2 emissions saved from 2002 to 2006 is 154,462 tons, with an average of 1,529.3 tons per facility. The average recommended energy cost savings per facility is

    Using a pair of different recycle oils from Wilsonville and {sup 1}H NMR, {sup 13}C NMR, gel permeation (GPC) chromatography, high pressure liquid chromatography (HPLC), and elemental analysis, no significant differences were observed between the composition of the recycle oil and that portion of the oil not absorbed by the coal. For these complex mixtures, coals are not selective absorbants. Since most of the heteroatoms responsible for most of the specific interactions have been removed by hydrogenolyses, this is perhaps not surprising. To address the issue of the role of hydrogen bond donors in the reused as hydrogen donor coal, tetralin and 2-t-butyltetralin were used as hydrogen donor solvents. This work is reported in detail in Section 2. The basic idea is that the presence of the t-butyl group on the aromatic ring will hinder or block diffusion of the hydrogen donor into the coal resulting in lower conversions and less hydrogen transferred with 2-t-butyltetralin than with tetralin. Observed was identical amounts of hydrogen transfer and nearly identical conversions to pyridine solubles for both hydrogen donors. Diffusion of hydrogen donors into the coal does not seem to play a significant role in coal conversion. Finally, in Section 3 is discussed the unfavorable impact on conversion of the structural rearrangements which occur when Illinois No. 6 coal is swollen with a solvent. We believe this rearrangement results in a more strongly associated solid leading to the diminution of coal reactions. Hydrogen donor diffusion does not seem to be a major factor in coal conversion while the structural rearrangement does. Both areas warrant further exploration.

    In the United States, more than 20 billion barrels of salt water are produced each year during oilfield operations. A tremendous economic incentive exists to reduce water production if that can be accomplished without significantly sacrificing hydrocarbon production. This three-year research project had three objectives. The first objective was to identify chemical blocking agents that will (a) during placement, flow readily through fractures without penetrating significantly into porous rock and with screening out or developing excessive pressure gradients and (b) at a predictable and controllable time, become immobile and resistant breakdown upon exposure to moderate to high pressure gradients. The second objective was to identify schemes that optimize placement of the above blocking agents. The third objective was to explain why gels and other chemical blocking agents reduce permeability to one phase (e.g., water) more than that to another phase (e.g., oil or gas). The authors also wanted to identify conditions that maximize this phenomenon. This project consisted of three tasks, each of which addressed one of the above objectives. This report describes work performed during the third and final period of the project. During this three-year project, they: (1) Developed a procedure and software for sizing gelant treatments in hydraulically fractured production wells; (2) Developed a method (based on interwell tracer results) to determine the potential for applying gel treatments in naturally fractured reservoirs; (3) Characterized gel properties during extrusion through fractures; (4) Developed a method to predict gel placement in naturally fractured reservoirs; (5) Made progress in elucidating the mechanism for why some gels can reduce permeability to water more than that to oil; (6) Demonstrated the limitations of using water/oil ratio diagnostic plots to distinguish between channeling and coning; and (7) Proposed a philosophy for diagnosing and attacking water

    UES, Inc. conducted a research and development program designed to establish conditions for ion implantation/mixing of suitable additives into the surfaces of bulk ceramics and metals for obtaining self-lubricating low friction and wear characteristics. The substrates considered were ZrO{sub 2}, Al{sub 2}O{sub 3}, Si{sub 3}N{sub 4}, steel and Ni-base superalloy. The lubricant additives chosen were BaF{sub 2}/CaF{sub 2}Ag, MoS{sub 2}, WS{sub 2}and B{sub 2}O{sub 3}. The initial tasks of the program were to synthesis these lubricant compounds by co-implantation of constituent elements if sufficient beams of desired elements were obtained. The final tasks were to investigate high energy (MeV) ion mixing of deposited coatings as well as to investigate ion beam assisted deposition using low energy ion beams. It was shown that MoS{sub 2} can be synthesized by co-implantation of Mo{sup +} and S{sup +} in ceramic materials with appropriate choice of energies to obtain nearly overlapping depth profiles. The sliding life of DC magnetron sputtered MoS{sub 2} films of thicknesses {approximately}7500{Angstrom} on ceramic materials such as sapphire, Si{sub 3}N{sub 4} and ZrO{sub 3} were improved by ten to thousand fold after 2 Mev Ag{sup +} ion mixing. Ion beam assisted deposition (IBAD) and ion beam mixing were utilized to fabricate self-lubricating coatings of CaF{sub 2}/Ag and BaF/CaF{sub 2}/Ag composites.

    This is the final report on DOE Award No. DE-FG03-92ER75838 A000, a three year matching grant program with Pacific Gas and Electric Company (PG and E) to support strengthening of the fission reactor nuclear science and engineering program at UCLA. The program began on September 30, 1992. The program has enabled UCLA to use its strong existing background to train students in technological problems which simultaneously are of interest to the industry and of specific interest to PG and E. The program included undergraduate scholarships, graduate traineeships and distinguished lecturers. Four topics were selected for research the first year, with the benefit of active collaboration with personnel from PG and E. These topics remained the same during the second year of this program. During the third year, two topics ended with the departure o the students involved (reflux cooling in a PWR during a shutdown and erosion/corrosion of carbon steel piping). Two new topics (long-term risk and fuel relocation within the reactor vessel) were added; hence, the topics during the third year award were the following: reflux condensation and the effect of non-condensable gases; erosion/corrosion of carbon steel piping; use of artificial intelligence in severe accident diagnosis for PWRs (diagnosis of plant status during a PWR station blackout scenario); the influence on risk of organization and management quality; considerations of long term risk from the disposal of hazardous wastes; and a probabilistic treatment of fuel motion and fuel relocation within the reactor vessel during a severe core damage accident.

    In 1990 the US Department of Energy initiated the Advanced Wind Turbine (AWT) Program to assist the growth of a viable wind energy industry in the US. This program, which has been managed through the National Renewable Energy Laboratory (NREL) in Golden, Colorado, has been divided into three phases: (1) conceptual design studies, (2) near-term product development, and (3) next-generation product development. The goals of the second phase were to bring into production wind turbines which would meet the cost goal of $0.05 kWh at a site with a mean (Rayleigh) windspeed of 5.8 m/s (13 mph) and a vertical wind shear exponent of 0.14. These machines were to allow a US-based industry to compete domestically with other sources of energy and to provide internationally competitive products. Information is given in the report on design values of peak loads and of fatigue spectra and the results of the design process are summarized in a table. Measured response is compared with the results from mathematical modeling using the ADAMS code and is discussed. Detailed information is presented on the estimated costs of maintenance and on spare parts requirements. A failure modes and effects analysis was carried out and resulted in approximately 50 design changes including the identification of ten previously unidentified failure modes. The performance results of both prototypes are examined and adjusted for air density and for correlation between the anemometer site and the turbine location. The anticipated energy production at the reference site specified by NREL is used to calculate the final cost of energy using the formulas indicated in the Statement of Work. The value obtained is $0.0514/kWh in January 1994 dollars. 71 figs., 30 tabs.

    Plastic coals are important feedstocks in coke manufacture, coal liquefaction, gasification, and combustion. During these processes, the thermoplastic behavior of these coals is also important since it may contribute to desirable or undesirable characteristics. For example, during liquefaction, the plastic behavior is desired since it leads to liquid-liquid reactions which are faster than solid-liquid reactions. During gasification, the elastic behavior is undesired since it leads to caking and agglomeration of coal particles which result in bed bogging in fixed or fluidized bed gasifiers. The plastic behavior of different coals was studied using a fast-response plastometer. A modified plastometer was used to measure the torque required to turn at constant angular speed a cone-shaped disk embedded in a thin layer of coal. The coal particles were packed between two metal plates which are heated electrically. Heating rates, final temperatures, pressures, and durations of experiment ranged from 200--800 K/s, 700--1300 K, vacuum-50 atm helium, and 0--40 s, respectively. The apparent viscosity of the molten coal was calculated from the measured torque using the governing equation of the cone-and-plate viscometer. Using a concentrated suspension model, the molten coal`s apparent viscosity was related to the quantity of the liquid metaplast present during pyrolysis. Seven coals from Argonne National Laboratory Premium Coal Sample Bank were studied. Five bituminous coals, from high-volatile to low-volatile bituminous, were found to have very good plastic behavior. Coal type strongly affects the magnitude and duration of plasticity. Hvb coals were most plastic. Mvb and lvb coals, though the maximum plasticity and plastic period were less. Low rank coals such as subbituminous and lignite did not exhibit any plasticity in the present studies. Coal plasticity is moderately well correlated with simple indices of coal type such as the elemental C,O, and H contents.

    The seasonally burned cerrados of Brazil are the largest savanna-type ecosystem of South America and their contribution to the global atmospheric nitrous oxide (N2O) budget is unknown. Four types of fire-scarred cerrado along a vegetation gradient from grassland to forest were investigated during the wet season of 1992/93. The effect of fire and subsequent water additions on epiodic emissions of N2O and the associated profile dynamic of soil/gas phase N2O concentrations were studied for several months. Additionally, the effect on episodic emissions of N2O of nitrate and glucose additions to a cerrado soil after fire and the associated profile dynamic of soil/gas phase N2O mixing ratios were determined. Finally, N2O episodic emissions in cerrado converted to corn, soybean, and pasture fields were investigated during one growing/wet season. Results showed N2O consumption/emission for the four fire-scared savanna ecosystems, for nitrogen and carbon fertilization, and for agriculture/pasture ranging from -0.3 to +0.7, 1.8 to 9.1, and 0.5 to 3.7 g N2O-N ha(exp -1) d(exp -1), respectively. During the wet season the cerrado biome does not appear to be a major source of N2O to the troposphere, even following fire events. However, the results of this study suggest that conversion of the cerrado to high input agriculture, with liming and fertilization, can increase N2O emissions more than ten fold.

    Chamberlain engineers designed a 3X compound parabolic concentrating (CPC) collector for the subject contract. The collector is a completely housed, 105.75 x 44.75 x 10.23-inch, 240-pound unit with six each evacuated receiver assemblies, a center manifold and a one-piece glass cover. A truncated version of a CPC trough reflector system and the General Electric Company tubular evacuated receiver have been integrated with a mass producible collector design suitable for operation at 250 to 450/sup 0/F. The key criterion for optimization of the design was minimization of the cost per Btu collected annually at an operating temperature of 400/sup 0/F. The reflector is a 4.1X design truncated to a total height of 8.0 inches with a resulting actual concentration ratio of 2.6 to 1. The manifold is an insulated area housing the fluid lines which connect the six receivers in series with inlet and outlet tubes extending from one side of the collector at the center. The reflectors are polished, anodized aluminum which are shaped by the roll form process. The housing is painted, galvanized steel, and the cover glass is 3/16-inch thick tempered, low iron glass. The collector requires four slope adjustments per year for optimum effectiveness. Chamberlain produced ten 3X CPC collectors for the subject contract. Two collectors were used to evaluate assembly procedures, six were sent to the project officer in Albuquerque, New Mexico, one was sent to Argonne National Laboratory for performance testing and one remained with the Company. A manufacturing cost study was conducted to estimate limited mass production costs, explore cost reduction ideas and define tooling requirements. The final effort discussed shows the preliminary design for application of a 3X CPC solar collector system for use in the Iowa State Capitol complex.

    Several new catalysts for phenol deoxygenation by CO were developed in our laboratories during the grant period. The deoxygenation of phenols by CO represents a.novel approach to the upgrading of coal liquids. The deoxygenation of phenols by CO is thermodynamically more favorable and potentially less expensive than current phenol hydrodeoxygenation (HDO) methods. The reaction was not known to be kinetically feasible until our recent discovery of appropriate catalysts. The catalyst precursor [Ir(triphos)({eta}{sup 4{minus}}C{sub 8}H{sub 12})][C1] was found to catalytically deoxygenate phenol and p-cresol. Reactions were conducted with varying amounts of AR-OH (Ar = C{sub 6}H{sub 5}, p-Me-C{sub 6}H{sub 4}), NaO-Ar, and catalyst precursor. In some reactions, triethyl amine was substituted for NaO-Ar to deprotonate the ArOH. All reactions took place at 55{degrees}C so that AR-OH was the solvent One atmosphere of CO was introduced into each reactor. Periodically, gasses were sampled by gas chromatography (GC) to monitor the disappearance of CO and the appearance of CO{sub 2}. After the amount of CO{sub 2} had reached a plateau, organic products were distilled from the reaction mixture and analyzed by high pressure liquid chromatography (HPLC). Significant quantities of arene (benzene or toluene) were obtained. These results are general. Initial use of phenol results in only benzene. Initial use of p-cresol results in only toluene. Control reactions eliminate the catalyst precursor as the source Of CO{sub 2} or arene. No evidence is obtained for diarylcarbonate formation. HPLC and GC data from consistently demonstrated that toluene and CO{sub 2} were the only products obtained from the deoxygenation of p-cresol by CO. These results were extended to a series of variously substituted phenolic and naptholic substrates related to those found in coal liquids.

    Over the past three decades, Earth scientists have made great strides in understanding our planet’s workings and history. Yet this progress has served principally to lay bare more fundamental questions about the Earth. Expanding knowledge is generating new questions, while innovative technologies and new partnerships with other sciences provide new paths toward answers. A National Academies committee was established to frame some of the great intellectual challenges inherent in the study of the Earth and planets. The goal was to focus on science, not implementation issues, such as facilities or recommendations aimed at specific agencies. The committee canvassed the geological community and deliberated at length to arrive at 10 questions: 1. How did Earth and other planets form? 2. What happened during Earth’s “dark age” (the first 500 million years)? 3. How did life begin? 4. How does Earth’s interior work, and how does it affect the surface? 5. Why does Earth have plate tectonics and continents? 6. How are Earth processes controlled by material properties? 7. What causes climate to change—and how much can it change? 8. How has life shaped Earth—and how has Earth shaped life? 9. Can earthquakes, volcanic eruptions, and their consequences be predicted? 10. How do fluid flow and transport affect the human environment? Written for graduate students, colleagues in sister disciplines, and program managers funding Earth and planetary science research, the report describes where the field stands, how it got there, and where it might be headed. Our hope is that the report will spark new interest in and support for the field by showing how Earth science can contribute to a wide range of issues—including some not always associated with the solid Earth—from the formation of the solar system to climate change to the origin of life. Its reach goes beyond the United States; the report is being translated into Chinese and distributed in China.

    This report is a summary of work supported by DOE grant No. DE-FGO5-87ER13795 that was completed or is still in progress. The stated purpose of this grant was to collect geochemical information (trace element, radiogenic isotope and stable oxygen and hydrogen isotope) on samples from core holes VC-I and VC-2a in the Valles caldera in order to establish a consistent detailed intracaldera stratigraphy and relate this to extracaldera volcanic rock units of the Jemez Mountains. Careful stratigraphic control of the intracaldera units is necessary to evaluate models of caldera formation, ignimbrite deposition, and resurgence. Combined stable and radiogenic isotope and trace element data will also provide major insights to petrogenesis of the Bandelier magma system. The composition of non-hydrothermally altered samples from outflow units of the Bandelier Tuff and related volcanics must be known to assess isotopic variations of intracaldera ignimbrite samples. On detailed examination of the VC-2a core samples, it became apparent that hydrothermal alteration is so extensive that no geochemical information useful for stratigraphic fingerprinting or petrogenesis could be obtained, and that correlation with other intracaldera units and extracaldera units must be made on the basis of stratigraphic position and gross lithologic characteristics. Accordingly, we emphasize geochemical data from the extracaldera Bandelier Tuffs and related units which will be useful for comparison with proposed drill hole VC-4 and for any future studies of the region. The stable isotope, radiogenic isotope and trace element data obtained from this project, combined with existing major and trace element data for volcanic rocks from this area, provide an extensive data base essential to future Continental Scientific Drilling Program projects in the Jemez Mountains of New Mexico.

    A certificate of graduate studies in Biobased Industrial Products is to be established at Kansas State University (KSU) along with the development of a similar program at Pittsburg State University, Pittsburg, KS. At KSU, the program of study will be coordinated through the steering committee of the Agricultural Products Utilization Forum (APUF); the certificate of graduate studies will be awarded through the Graduate School of Kansas State University. This certificate will establish an interdisciplinary program of study that will: (1) ensure participating students receive a broad education in several disciplines related to Biobased Industrial Products, (2) provide a documented course of study for students preferring a freestanding certificate program, and (3) provide a paradigm shift in student awareness away from petroleum-based feedstocks to the utilization of renewable resources for fuels and chemical feedstocks. The academic program described herein will accomplish this goal by: (1) providing exposure to several academic disciplines key to Biobased Industrial Products; (2) improving university/industry collaboration through an external advisory board, distance learning opportunities, and student internships; (3) expanding the disciplines represented on the students' supervisory committee; (4) establishing a seminar series on Biobased Industrial Products that draws upon expert speakers representing several disciplines; and (5) increasing collaboration between disciplines. Numerous research programs emphasizing Biobased Industrial Products currently exist at KSU and PSU. The certificate of graduate studies, the emphasis on interdisciplinary collaboration within the students? thesis research, the proposed seminar series, and formation of an industrial advisory board will: (1) provide an interdisciplinary academic experience that spans several departments, four colleges, four research centers, and two universities; (2) tangibly promote collaboration between KSU

    1998-07-22

    The Detector Development Group at the University of Florida has identified the only known optically radiation hard polymer, scintillator and wavelength shifter materials. The authors summarize their findings here. They conducted an extensive study of siloxane polymers using monomers of dimethyl, diphenyl and methylphenyl siloxanes. An important finding of that study was that polymethylphenylsiloxane is a candidate polymer for use at the SSC. However, the most important result of that work was the demonstration of the existence of optical polymers with extreme resistance to radiation damage. It held out the promise that other possibly more convenient polymers with similar properties could be identified. The first high viscosity, transparent, radiation hard siloxane with high fluor solubility was processed into prototype plates. The authors propose a mechanism to account for radiation induced annealable color center formation in commercial scintillator polymers such as PS and PMMA. The authors produced analogues of these polymers with T{sub g} < room temperatures. These polymers are optically radiation hard. The University of Florida has applied for a patent on this breakthrough discovery. It was found that dye mobility for radiation hard elastomers (T{sub g} < room temperature) was unacceptable over a period of one year. Dyes would tend to crystallize on the surface of the plates. The work concentrated therefore on thermoplastic polymers which had T{sub g} {approximately} 50 C (i.e., high enough for structural stability) and with high color center annealing rate such as polyisobutylmethacrylate. These polymers were both radiation hard and had minimal dye migration. The University of Florida has a patent on these materials. These materials were extruded and tested for stability and found adequate for operation up to 10 Mrad at the SSC.

    Recent research efforts in direct coal liquefaction are focused on lowering the level of reaction severity, identification and determination of the causes of retrogressive reactions, and improving the economics of the process. Ambient pretreatment of coals using methanol and a trace amount of hydrochloric acid was extensively studied in connection with low severity coal liquefaction. Ambient pretreatment of eight Argonne coals using methanol/HCl improved THF-soluble conversions 24.5 wt % (maf basis) for Wyodak subbituminous coal and 28.4 wt % for Beulah-Zap lignite with an average increase of 14.9 wt % for the eight Argonne coals at 623 K (350{degrees}C) reaction temperature and 30 minutes reaction time. Optimal pretreatment conditions were determined using Wyodak and Illinois No. 6 coals. Acid concentration was the most important pretreatment variable studied; liquefaction reactivity increased with increasing acid concentration up to 2 vol %. The FTIR spectra of treated and untreated Wyodak coal samples demonstrated formation of carboxylic functional groups during pretreatment, a result of divalent (Ca, Mg) cationic bridge destruction. The extent of liquefaction reactivity directly correlated with the amount of calcium removed during pretreatment, and results from calcium ``addback`` experiments supported the observation that calcium adversely affected coal reactivity at low severity reaction conditions. Model compound studies using benzyl phenyl ether demonstrated that calcium cations catalyzed retrogressive reactions, inhibited hydrogenation reactions at low severity reaction conditions, and were more active at higher reaction temperatures. Based on kinetic data, mechanisms for hydrogenation-based inhibition and base-catalyzed retrogressive reactions are proposed. The base-catalyzed retrogressive reactions are shown to occur via a hydrogen abstraction mechanism where hydrogenation inhibition reactions are shown to take place via a surface quenching mechanism.

    During this research period, researchers at International Solar Electric Technology (ISET) concentrated their efforts on three different areas of research. Within the National CIS R and D Team, ISET participated in the substrate/Mo interactions working group and investigated issues such as Na diffusion from the soda-lime glass substrate into the Mo layers and CIS films. Researchers determined that the Na content within the Mo layers was not a strong function of the nature of the Mo film. However, they found that diffusion through the Mo layers was a function of the Mo film characteristics as well as a very strong function of the CIS growth process itself. Researchers showed conclusively that the Na resided on the grain boundaries of CIS layers. Another team activity involved evaluation of CdS-free CIS solar cells. ZnO/CIS junctions prepared by the two-stage process showed light-soaking effects. Cells left under illumination improved in efficiency and were similar to the CdS/CIS junctions. After storage in the dark, however, efficiency deteriorated greatly for the ZnO/CIS device, most of the decline coming from the open-circuit voltage values. Much of the effort during this period was spent on developing a low-cost, non-vacuum CIS deposition technique. The method developed involves particulate deposition and formation of precursor layers followed by the conversion of these layers into CIS. Test modules of 40--60 cm{sup 2} were adapted to understand the issues involved in this novel technology. At the present time, the submodule efficiencies are 6--7%. Single-cell efficiencies are in the 10--13% range.

The Mercedes Team, together with its partners, tested the technology by operating and fueling hydrogen fuel cell vehicles under real world conditions in varying climate, terrain and driving conditions. Vehicle and infrastructure data was collected to monitor the progress toward the hydrogen vehicle and infrastructure performance targets of $2.00 to 3.00/gge hydrogen production cost and 2,000-hour fuel cell durability. Finally, to prepare the public for a hydrogen economy, outreach activities were designed to promote awareness and acceptance of hydrogen technology. DTE, BP and NextEnergy established hydrogen filling stations using multiple technologies for on-site hydrogen generation, storage and dispensing. DTE established a hydrogen station in Southfield, Michigan while NextEnergy and BP worked together to construct one hydrogen station in Detroit. BP constructed another fueling station in Burbank, California and provided a full-time hydrogen trailer at San Francisco, California and a hydrogen station located at Los Angeles International Airport in Southern, California. Stations were operated between 2005 and 2011. The Team deployed 30 Gen I Fuel Cell Vehicles (FCVs) in the beginning of the project. While 28 Gen I F-CELLs used the A-Class platform, the remaining 2 were Sprinter delivery vans. Fuel cell vehicles were operated by external customers for real-world operations in various regions (ecosystems) to capture various driving patterns and climate conditions (hot, moderate and cold). External operators consisted of F-CELL partner organizations in California and Michigan

Concrete crusher liner wear plates provided by an EHT customer and made of 1045 steel, had the same surface hardness as the plates made of more expensive, pre-hardened high alloy HARDOX-500 material supplied by a Swedish company and used currently by the EHT customer. The 1045 material intensively quenched wear plates are currently in the field. Concrete block molding machine wear plates provided by an IQT customer and made of 8620 steel were processed at the AST production IQ system using a 40% reduced carburization cycle. An effective case depth in the intensively quenched wear plates was the same as in the standard, oil quenched parts. Base keys provided by an EHT customer and made of 8620 steel were processed using a 40% reduced carburization cycle. The intensively quenched parts showed the same performance as standard parts. IQT introduced the IQ process in heat treat practices of three commercial heat-treating shops: Akron Steel Treating Co., Summit Heat Treating Co. and Euclid Heat Treating Co. CWRU conducted a material characterization study for a variety of steels to develop a database to support changing/modification of recognized standards for quenching steel parts. IQT conducted a series of IQ workshops, published seven technical papers and participated in ASM Heat Treating Society conference and exposition and in Furnace North America Show. IQT designed and built a fully automated new IQ system installed at the Center for Intensive Quenching.

    The objective of this project is to develop practical, cost effective methods for stabilizing biomass-derived fast pyrolysis oil for at least six months of storage under ambient conditions. The U.S. Department of Energy has targeted three strategies for stabilizing bio-oils: (1) reducing the oxygen content of the organic compounds comprising pyrolysis oil; (2) removal of carboxylic acid groups such that the total acid number (TAN) of the pyrolysis oil is dramatically reduced; and (3) reducing the charcoal content, which contains alkali metals known to catalyze reactions that increase the viscosity of bio-oil. Alkali and alkaline earth metals (AAEM), are known to catalyze decomposition reactions of biomass carbohydrates to produce light oxygenates that destabilize the resulting bio-oil. Methods envisioned to prevent the AAEM from reaction with the biomass carbohydrates include washing the AAEM out of the biomass with water or dilute acid or infusing an acid catalyst to passivate the AAEM. Infusion of acids into the feedstock to convert all of the AAEM to salts which are stable at pyrolysis temperatures proved to be a much more economically feasible process. Our results from pyrolyzing acid infused biomass showed increases in the yield of anhydrosugars by greater than 300% while greatly reducing the yield of light oxygenates that are known to destabilize bio-oil. Particulate matter can interfere with combustion or catalytic processing of either syngas or bio-oil. It also is thought to catalyze the polymerization of bio-oil, which increases the viscosity of bio-oil over time. High temperature bag houses, ceramic candle filters, and moving bed granular filters have been variously suggested for syngas cleaning at elevated temperatures. High temperature filtration of bio-oil vapors has also been suggested by the National Renewable Energy Laboratory although there remain technical challenges to this approach. The fast pyrolysis of biomass yields three main organic

    Project OASIS (Operation of Advanced Structures, Interfaces and Sub-components for MEAs) was a 12 month project that ran from 1st September 2008 to 31st August 2009, and was managed by the Department of Energy Office of Science, Chicago Office, as Award No DE-FG02-08ER64658, with Johnson Matthey Fuel Cells Inc. as the sole contractor. The project was completed on schedule, with technical successes (details below) and payment of the full grant award made by DOE. The aim of the project was the development of membrane electrode assemblies (MEAs) for H2/air polymer electrolyte membrane (PEM) fuel cells that would give higher performance under hot/dry and dry operating conditions, ideally with no loss of performance under wet conditions. Reducing or eliminating the need for humidifying the incoming gases will allow significant system cost and size reduction for many fuel cell applications including automotive, stationary and back-up power, and portable systems. Portable systems are also of particular interest in military markets. In previous work Johnson Matthey Fuel Cells had developed very stable, corrosion-resistant catalysts suitable for resisting degradation by carbon corrosion in particular. These materials were applied within the OASIS project as they are considered necessary for systems such as automotive where multiple start-stop events are experienced. These catalysts were contrasted with more conventional materials in the design of catalyst layers and novel microporous layers (MPLs) and gas diffusion layer (GDL) combinations were also explored. Early on in the work it was shown how much more aggressive high temperature operation is than dry operation. At the same humidity, tests at 110?C caused much more dehydration than tests at 80?C and the high temperature condition was much more revealing of improvements made to MEA design. Alloy catalysts were introduced and compared with Pt catalysts with a range of particle sizes. It was apparent that the larger

    This project designed characterization techniques for thin films of complex matter and other materials in the terahertz spectral region extending from approximately 100 GHz to 4000 GHz (4 THz) midway between radio waves and light. THz has traditionally been a difficult region of the spectrum in which to conduct spectroscopic measurements. The “THz gap” arises from the nature of the sources and detectors used in spectroscopy both at the optical (high frequency) side and electronic (low frequency) side of the gap. To deal with the extremely rapid oscillations of the electric field in this frequency region this research project adapted techniques from both the electronics and optics technologies by fabricating microscopic antennas and driving them with short optical pulses. This research technique creates nearly single cycle pulses with extremely broad spectral bandwidth that are able to cover the THz spectral range with a single measurement. The technique of THz time domain spectroscopy (THz-TDS) has seen increasing use and acceptance in laboratories over the past fifteen years. However significant technical challenges remain in order to allow THz-TDS to be applied to measurement of solid materials, particularly thin films and complex matter. This project focused on the development and adaptation of time domain THz measurement techniques to investigate the electronic properties of complex matter in the terahertz frequency region from 25 GHz to beyond 5 THz (<1 inv. cm to >165 inv. cm). This project pursued multiple tracks in adapting THz Time Domain Spectroscopy (THz-TDS) to measurement of complex matter. The first, and most important, is development of a reliable methods to characterize the complex dielectric constant of thin films with high accuracy when the wavelength of the THz radiation is much longer than the thickness of the film. We have pursued several techniques for measurement of thin films. The most promising of these are waveguide spectroscopy and

    The early precursors of laser ultrasonics on paper were Prof. Y. Berthelot from the Georgia Institute of Technology/Mechanical Engineering department, and Prof. P. Brodeur from the Institute of Paper Science and Technology, both located in Atlanta, Georgia. The first Ph.D. thesis that shed quite some light on the topic, but also left some questions unanswered, was completed by Mont A. Johnson in 1996. Mont Johnson was Prof. Berthelot's student at Georgia Tech. In 1997 P. Brodeur proposed a project involving himself, Y. Berthelot, Dr. Ken Telschow and Mr. Vance Deason from INL, Honeywell-Measurex and Dr. Rick Russo from LBNL. The first time the proposal was not accepted and P. Brodeur decided to re-propose it without the involvement from LBNL. Rick Russo proposed a separate project on the same topic on his side. Both proposals were finally accepted and work started in the fall of 1997 on the two projects. Early on, the biggest challenge was to find an optical detection method which could detect laser-induced displacements of the web surface that are of the order of .1 micron in the ultrasonic range. This was to be done while the web was having an out-of-plane amplitude of motion in the mm range due to web flutter; while moving at 10 m/s to 30 m/s in the plane of the web, on the paper machine. Both teams grappled with the same problems and tried similar methods in some cases, but came up with two similar but different solutions one year later. The IPST, GT, INL team found that an interferometer made by Lasson Technologies Inc. using the photo-induced electro-motive force in Gallium Arsenide was able to detect ultrasonic waves up to 12-15 m/s. It also developed in house an interferometer using the Two-Wave Mixing effect in photorefractive crystals that showed good promises for on-line applications, and experimented with a scanning mirror to reduce motion-induced texture noise from the web and improve signal to noise ratio. On its side, LBNL had the idea to combine a

    Conversion of biomass to sugars plays a central in reducing our dependence on petroleum, as it allows production of a wide range of biobased fuels and chemicals, through fermentation of those sugars. The DECREASE project delivers an effective enzyme cocktail for this conversion, enabling reduced costs for producing advanced biofuels such as cellulosic ethanol. Benefits to the public contributed by growth of the advanced biofuels industry include job creation, economic growth, and energy security. The DECREASE primary project objective was to develop a two-fold improved enzyme cocktail, relative to an advanced cocktail (CZP00005) that had been developed previously (from 2000- 2007). While the final milestone was delivery of all enzyme components as an experimental mixture, a secondary objective was to deploy an improved cocktail within 3 years following the close of the project. In February 2012, Novozymes launched Cellic CTec3, a multi-enzyme cocktail derived in part from components developed under DECREASE. The externally validated performance of CTec3 and an additional component under project benchmarking conditions indicated a 1.8-fold dose reduction in enzyme dose required for 90% conversion (based on all available glucose and xylose sources) of NREL dilute acid pretreated PCS, relative to the starting advanced enzyme cocktail. While the ability to achieve 90% conversion is impressive, targeting such high levels of biomass digestion is likely not the most cost effective strategy. Novozymes techno economic modeling showed that for NREL's dilute acid pretreated corn stover (PCS), 80% target conversion enables a lower total production cost for cellulosic ethanol than for 90% conversion, and this was also found to be the case when cost assumptions were based on the NREL 2002 Design Report. A 1.8X dose-reduction was observed for 80% conversion in the small scale (50 g) DECREASE benchmark assay for CTec3 and an additional component. An upscaled experiment (in 0.5 kg

    Polyhydroxyalkanotes (PHAs), a group of newly developed, commercially available biopolymers, and their composites have the potential to replace petroleum-based amorphous and semicrystalline polymers currently in use for consumer packaging, adhesives, and coating applications and to have significant advantages in medical applications such as tissue engineering. While the potential of PHAs is recognized in the literature and has even been realized in some cases, knowledge of these systems is decades behind that of synthetic polymers. Composites based on PHAs, furthermore, are just emerging in the research community. We argue that widespread adoption of nano-enhanced PHA materials can only be achieved through a proper characterization of the nanofiller morphology and its impact on the polymer matrix. Our goal is to build a robust understanding of the structure-processing relationships of PHAs to make it possible to achieve fundamental control over the final properties of these biopolymers and their bionanocomposites and to develop cost-effective manufacturing technologies for them. With the ultimate goal to design PHA polymer nanocomposites with tailored properties, we have performed a systematic study of the influence of cooling rate on the thermal properties and morphology of linear PHAs (PHB Mw = 690,000 g/mol; PHBV Mw = 407,000 g/mol, 8 mol % HV) and branched (PHBHx, Mw = 903, 000 g/mol, 7.2 mol % Hx) copolymers. Structure-property relations for silica/PHBHx nanocomposites were also investigated. Our studies show that simple two-phase composite models do not account for the molecular weight dependent enhancement in the modulus. Although improvement of the mechanical properties (stiffness/modulus and toughness) must be due to alteration of the matrix by the nanoparticle filler, the observed improvement was not caused by the change of crystallinity or spherulitic morphology. Since the mechanical properties of polymer nanocomposites can be affected by many factors

    Firstly, we study the final masses of giant planets growing in protoplanetary disks through capture of disk gas, by employing an empirical formula for the gas capture rate and a shallow disk gap model, which are both based on hydrodynamical simulations. The shallow disk gaps cannot terminate growth of giant planets. For planets less massive than 10 Jupiter masses, their growth rates are mainly controlled by the gas supply through the global disk accretion, rather than their gaps. The insufficient gas supply compared with the rapid gas capture causes a depletion of the gas surface density even at the outside of the gap, which can create an inner hole in the protoplanetary disk. Our model can also predict how deep the inner hole is for a given planet mass. Secondly, our findings are applied to the formation of our solar system. For the formation of Jupiter, a very low-mass gas disk with a few or several Jupiter masses is required at the beginning of its gas capture because of the non-stopping capture. Such a low-mass gas disk with sufficient solid material can be formed through viscous evolution from an initially ˜10AU-sized compact disk with the solar composition. By the viscous evolution with a moderate viscosity of α˜10-3, most of disk gas accretes onto the sun and a widely spread low-mass gas disk remains when the solid core of Jupiter starts gas capture at t˜107 yrs. The depletion of the disk gas is suitable for explaining the high metallicity in giant planets of our solar system. A very low-mass gas disk also provides a plausible path where type I and II planetary migrations are both suppressed significantly. In particular, we also show that the type II migration of Jupiter-size planets becomes inefficient because of the additional gas depletion due to the rapid gas capture by themselves.

For the formation of Jupiter, a very low-mass gas disk of several Jupiter masses is required at the beginning of its gas capture because of the continual capture. Such a low-mass gas disk with sufficient solid material can be formed through viscous evolution from a compact disk of initial size ∼10 au.

    The U.S. Geological Survey (USGS) has completed an assessment of the undiscovered oil and associated gas resources of the Upper Devonian to Lower Mississippian Bakken Formation in the U.S. portion of the Williston Basin of Montana and North Dakota and within the Williston Basin Province. The assessment is based on geologic elements of a total petroleum system (TPS), which include (1) source-rock distribution, thickness, organic richness, maturation, petroleum generation, and migration; (2) reservoir-rock type (conventional or continuous), distribution, and quality; and (3) character of traps and time of formation with respect to petroleum generation and migration. Framework studies in stratigraphy and structural geology and modeling of petroleum geochemistry, combined with historical exploration and production analyses, were used to estimate the undiscovered, technically recoverable oil resource of the Bakken Formation. Using this framework, the USGS defined a Bakken-Lodgepole TPS and seven assessment units (AU) within the system. For the Bakken Formation, the undiscovered oil and associated gas resources were quantitatively estimated for six of these AUs.

    Microbially mediated metabolisms have been identified as a significant factor either directly or indirectly impacting the fate and transport of heavy metal/radionuclide contaminants. To date microorganisms have been isolated from contaminated environments. Examination of annotated finished genome sequences of many of these subsurface isolates from DOE sites, revealed evidence of prior viral infection. To date the role that viruses play influencing microbial mortality and the resulting community structure which directly influences biogeochemical cycling in soils and sedimentary environments remains poorly understood. The objective of this exploratory study was to investigate the role of viral infection of subsurface bacteria and the formation of contaminant-bearing viral particles. This objective was approached by examining the following working hypotheses: (i) subsurface microorganisms are susceptible to viral infections by the indigenous subsurface viral community, and (ii) viral surfaces will adsorb heavy metals and radionuclides. Our results have addressed basic research needed to accomplish the BER Long Term Measure to provide sufficient scientific understanding such that DOE sites would be able to incorporate coupled physical, chemical and biological processes into decision making for environmental remediation or natural attenuation and long-term stewardship by establishing viral-microbial relationships on the subsequent fate and transport of heavy metals and radionuclides. Here we demonstrated that viruses play a significant role in microbial mortality and community structure in terrestrial subsurface sedimentary systems. The production of viral-like particles within subsurface sediments in response to biostimulation with dissolved organic carbon and a terminal electron acceptor resulted in the production of viral-like particles. Organic carbon alone did not result in significant viral production and required the addition of a terminal electron acceptor

    The IAU Commission 4 Working Group on Standardizing Access to Ephemerides recommends the use of the Spacecraft and Planet Kernel (SPK) format to provide a uniform format for the position ephemerides of planets and other natural solar system bodies, and the use of the Planetary Constants Kernel (PCK) for the orientation of these bodies. These formats are used by the SPICE system, developed by the Navigation and Ancillary Information Facility of NASA’s Jet Propulsion Laboratory. The working group's final report is currently undergoing final preparations for publication. A long version of this report will be available at the IAU Commission 4 - Ephemerides (or its successor) web site. This long version will contain a full description of that portion of the SPK and PCK formats required to duplicate these file types for this application.

    Executive Summary This Final Report for the "Development of Molten-Salt Heat Transfer Fluid (HTF) Technology for Parabolic Trough Solar Power Plants” describes the overall project accomplishments, results and conclusions. Phase 1 analyzed the feasibility, cost and performance of a parabolic trough solar power plant with a molten salt heat transfer fluid (HTF); researched and/or developed feasible component options, detailed cost estimates and workable operating procedures; and developed hourly performance models. As a result, a molten salt plant with 6 hours of storage was shown to reduce Thermal Energy Storage (TES) cost by 43.2%, solar field cost by 14.8%, and levelized cost of energy (LCOE) by 9.8% - 14.5% relative to a similar state-of-the-art baseline plant. The LCOE savings range met the project’s Go/No Go criteria of 10% LCOE reduction. Another primary focus of Phase 1 and 2 was risk mitigation. The large risk areas associated with a molten salt parabolic trough plant were addressed in both Phases, such as; HTF freeze prevention and recovery, collector components and piping connections, and complex component interactions. Phase 2 analyzed in more detail the technical and economic feasibility of a 140 MWe,gross molten-salt CSP plant with 6 hours of TES. Phase 2 accomplishments included developing technical solutions to the above mentioned risk areas, such as freeze protection/recovery, corrosion effects of applicable molten salts, collector design improvements for molten salt, and developing plant operating strategies for maximized plant performance and freeze risk mitigation. Phase 2 accomplishments also included developing and thoroughly analyzing a molten salt, Parabolic Trough power plant performance model, in order to achieve the project cost and performance targets. The plant performance model and an extensive basic Engineering, Procurement, and Construction (EPC) quote were used to calculate a real levelized cost of energy (LCOE) of 11.50

    accessible for hydrogen activation. Of the impurities studied, CO, NH3, perchloroethylene (also known as tetrachloroethylene), tetrahydrofuran, diborane, and metal cations had significant negative effects on the components in a fuel cell. While CO has no effect on the Nafion, it significantly poisons the Pt catalyst by adsorbing and blocking hydrogen activation. The effect can be reversed with time once the flow of CO is stopped. NH3 has no effect on the Pt catalyst at fuel cell conditions; it poisons the proton sites on Nafion (by forming NH4+ cations), decreasing drastically the proton conductivity of Nafion. This poisoning can slowly be reversed once the flow of NH3 is stopped. Perchloroethylene has a major effect on fuel cell performance. Since it has little/no effect on Nafion conductivity, its poisoning effect is on the Pt catalyst. However, this effect takes place primarily for the Pt catalyst at the cathode, since the presence of oxygen is very important for this poisoning effect. Tetrahydrofuran was shown not to impact Nafion conductivity; however, it does affect fuel cell performance. Therefore, its primary effect is on the Pt catalyst. The effect of THF on fuel cell performance is reversible. Diborane also can significant affect fuel cell performance. This effect is reversible once diborane is removed from the inlet streams. H2O2 is not an impurity usually present in the hydrogen or oxygen streams to a fuel cell. However, it is generated during fuel cell operation. The presence of Fe cations in the Nafion due to system corrosion and/or arising from MEA production act to catalyze the severe degradation of the Nafion by H2O2. Finally, the presence of metal cation impurities (Na+, Ca 2+, Fe3+) in Nafion from MEA preparation or from corrosion significantly impacts its proton conductivity due to replacement of proton sites. This effect is not reversible. Hydrocarbons, such as ethylene, might be expected to affect Pt or Nafion but do not at a typical fuel cell

The article also provides a novel synthesis of surface- and satellite-based Arctic cloud observations that show how much the new freezedry parameterization improves the simulated cloud amount in high latitudes (Fig. 3). Freezedry has been incorporated into the CCSM3.5 version, in which it successfully limits the excessive polar clouds, and may be used in CCSM4. Material from this work is also appearing in a synthesis article on future Arctic cloud changes (Vavrus, D. Waliser, J. Francis, and A. Schweiger, 'Simulations of 20th and 21st century Arctic cloud amount in the global climate models assessed in the IPCC AR4', accepted in Climate Dynamics) and was used in a collaborative paper on Arctic cloud-sea ice coupling (Schweiger, A., R. Lindsay, S. Vavrus, and J. Francis, 2008: Relationships between Arctic sea ice and clouds during autumn. J. Climate, 21, 4799-4810.). This research was presented at the 2007 CCSM Annual Workshop, as well as the CCSM's 2007 Atmospheric Model Working Group and Polar Working Group Meetings. The findings were also shown at the 2007 Climate Change Prediction Program's Science Team Meeting. In addition, I served as an instructor at the International Arctic Research Center's (IARC) Summer School on Arctic Climate Modeling in Fairbanks this summer, where I presented on the challenges and techniques used in simulating polar clouds. I also contributed to the development of a new Arctic System Model by attending a workshop in Colorado this summer on this fledgling project. Finally, an outreach activity for the general public has been the development of an interactive web site () that displays Arctic cloud amount in the CMIP3 climate model archive under present and future scenarios. This site allows users to make polar and global maps of a variety of climate variables to investigate the individual and ensemble-mean GCM response to greenhouse

    This compendium of technical papers represents three years of work in the investigation of the anaerobic biodegradation of tetrachloroethylene (PCE). Cornell researchers had previously developed a methanol (MeOH)/PCE enrichment culture which dechlorinates high concentrations of PCE and other chlorinated ethenes to ethene (ETH), representing complete detoxification. This culture dechlorinates PCE at unprecedented, high rates with efficient use of MeOH as the electron donor for reductive dechlorination. However, research at Cornell showed that MeOH was not the direct donor for PCE dechlorination, but rather H{sub 2}. MeOH and other reductants found to support dechlorination merely serve as H{sub 2} precursors. Three alternative electron donors (ethanol, butyrate, and lactate) were evaluated to circumvent the problem of methanogenic competition for the supplied donor. The final selected substrate was used in a continuous-flow reactor study with the H{sub 2}/PCE enrichment culture. Engineering studies examined the kinetics of chlorinated ETH utilization with emphasis on vinyl chloride (VC) dechlorination to ETH. Acclimation and induction issues were explored. Microbiological studies towards a better understanding of the nature and the requirements of the dechlorinating organisms were explored. The nutrition of the dechlorinating organisms was examined with the goal of finding and identifying reliable high-potency sources if the nutrients.

    A major program of university research, longer-ranged and more fundamental in approach than industrial research, into basic mechanisms of enhancing petroleum recovery and into underlying physics, chemistry, geology, applied mathematics, computation, and engineering science has been built at Minnesota. The 1982 outputs of the interdisciplinary team of investigators were again ideas, instruments, techniques, data, understanding and skilled people: forty-one scientific and engineering papers in leading journals; four pioneering Ph.D. theses; numerous presentations to scientific and technical meetings, and to industrial, governmental and university laboratories; vigorous program of research visits to and from Minnesota; and two outstanding Ph.D.'s to research positions in the petroleum industry, one to a university faculty position, one to research leadership in a governmental institute. This report summarizes the 1982 papers and theses and features sixteen major accomplishments of the program during that year. Abstracts of all forty-five publications in the permanent literature are appended. Further details of information transfer and personnel exchange with industrial, governmental and university laboratories appear in 1982 Quarterly Reports available from the Department of Energy and are not reproduced here. The Minnesota program continues in 1983, notwithstanding earlier uncertainty about the DOE funding which finally materialized and is the bulk of support. Supplemental grants-in-aid from nine companies in the petroleum industry are important, as are the limited University and departmental contributions. 839 references, 172 figures, 29 tables.

    This final technical report documents the accomplishments of the program of research entitled ``Radiation Disorder and Aperiodicity in Irradiated Ceramics`` for the period June 22, 1989--June 21, 1992. This research forms the latest part on an on-going program, begun at MIT in 1983 under DOE support, which has had as its objectives investigation of the responses in radiation environments of ceramics heavily-irradiated with electrons, neutrons and ions, with potential applications to fusion energy technology and high-level nuclear waste storage. Materials investigated have included SiO{sub 2}, MgAl{sub 2}O{sub 4}, Al{sub 23}O{sub 27}N{sub 5}, SiC, BeO, LiAlO{sub 2}, Li{sub 2}ZrO{sub 3}, CaTiO{sub 3}KTaO{sub 3} and Ca(Zr, Pu)Ti{sub 2}O{sub 7}. The program initially proposed for 1989 had as its major objectives two main thrusts: (1) research on defect aggregation in irradiated non-oxide ceramics, and (2) research on irradiation-induced amorphization of network silicas and phosphates.

    This is the final technical report on a project which undertook to develp and test scintillating optical fibers for use in a fine grained hodoscope for experiments in High Energy Physics. After a brief discussion of the need for such a device in experiments in high rate environments, a description is given of the process of drawing and cladding plastic scintillator to form scintillating optical fibers. This is followed by a description of the test procedures used to evaluate the resultant fibers both in the laboratory and at the accelerator. A discussion of three possible readout schemes then follows. These are individual photomultiplier tubes, avalanche photodiodes and microchannel plates with segmented anodes. The results of this study are then presented. The present status of the project is then summarized, in which it is pointed out that significant improvement in useful fiber length has been achieved as a result of this development program. The difficulty of quality control in fiber production remains a serious limitation, and a satisfactory readout scheme with good optical coupling between many hodoscope elements and photodetectors has yet to be achieved.

    The objective of this work was to develop catalyzed nanoporous materials that have superior hydrogen uptake between 300K and 400K and moderate pressures. Platinum nanoparticles were introduced to both activated carbons (ACs) and microporous metal organic frameworks (MMOFs) in order to dissociate molecular hydrogen into an active hydrogen species that diffuses from the catalyst to weakly chemisorbs to the AC/MMOF support; this combined sequence is referred to as the hydrogen spillover mechanism. For all materials studied, maximum excess hydrogen uptake was 1-1.4 wt% (excess) at 300K, falling short of DOE storage goals (5.5 wt% by 2015). Select Pt/AC materials (after in situ catalyst activation) had high uptake (up to 1.4 wt%) at low pressure which significantly exceeded that expected for physisorption. The uptake was not correlated to size of Pt catalyst, but appeared to be associated with high surface activity of the AC support and the methodology of catalyst doping. Multiple techniques were explored to introduce Pt nanoparticles into MMOFs, but most led to significant structural degradation. Ultimately, a ‘pre-bridge’ (PB) technique was used to introduce Pt/AC catalysts into MMOFs, as the PB technique led to virtually non-detectable changes in structure. At high pressure, hydrogen spillover of ~1 wt% (excess) to a PB-MMOF was very slow (i.e. >80 hours at 70-80 bar), which can be attributed to high diffusion barriers in a complex three-surface domain material (Pt, AC, MMOF) as well as unexpected evidence for mechanical instability of the undoped MMOF precursor. In a low-pressure comparison study of three PB-MMOFs, we found evidence that the doping technique may introduce defects which may contribute to enhanced adsorption at 300K. However, we could not rule out the effect of active Pt sites, as common predictors of adsorption generally favored the materials without Pt. Furthermore, spectroscopic evidence provided definitive evidence of weak hydrogen chemisorption to two MMOFs and AC, and was found only for materials containing Pt catalyst. Overall, high uptake via hydrogen spillover requires high catalytic activity and an energy neutral surface landscape for ready diffusion, with little to no correlation to the size of the Pt nanoparticle or textural properties (i.e. surface area or porosity) of the AC or MMOF support.

    The purpose of this grant was to experimentally investigate asymmetry-induced radial transport in a non-neutral (Penning-Malmberg) plasma trap. These traps provide an excellent platform for transport studies since the plasmas are generally well confined. One can then study transport in a controlled manner: the plasma is perturbed and the resulting transport measured. The focus of this research is the transport produced by applied asymmetric electric fields. The main results of our research concern (1) the theory of asymmetry-induced transport, (2) an absolute comparison of theory predictions with experimental results, (3) the amplitude scaling of the transport, (4) the frequency dependence of the transport, (5) the development of techniques to determine the relative contribution of mobility and diffusion to the transport, and (6) measuring the effect of small axial magnetic variations on the transport.

    As proposed, the main effort in this project is the development of software capable of performing real-time monitoring of micro-seismic activity recorded by an array of sensors deployed around an EGS. The main milestones are defined by the development of software to perform the following tasks: • Real-time micro-earthquake detection and location • Real-time detection of shear-wave splitting • Delayed-time inversion of shear-wave splitting These algorithms, which are discussed in detail in this report, make possible the automatic and real-time monitoring of subsurface fracture systems in geothermal fields from data collected by an array of seismic sensors. Shear wave splitting (SWS) is parameterized in terms of the polarization of the fast shear wave and the time delay between the fast and slow shear waves, which are automatically measured and stored. The measured parameters are then combined with previously measured SWS parameters at the same station and used to invert for the orientation (strike and dip) and intensity of cracks under that station. In addition, this grant allowed the collection of seismic data from several geothermal regions in the US (Coso) and Iceland (Hengill) to use in the development and testing of the software.

    The City of Albuquerque Aviation Department began planning for an alternative fuels facility in 1999 and began actively pursuing funding for the project in 2000. The original project scope was intended to provide a fueling station that provided unleaded gasoline, E-85, diesel, compressed natural gas (CNG) and propane. When the tragedy of 9/11 occurred, all capital projects were put on hold and then reassessed to validate needs and priorities. The alternative fuels station was scaled back to a CNG facility to: (1) Provide fuel for the common shuttle that served the rental car facilities at the airport; (2) Provide a CNG fuel center for use by all levels of government for vehicle fueling; (3) Provide another CNG facility near the interstate to improve the State network for CNG fueling; (4) Provide a backup fueling facility for the University of New Mexico and the City of Albuquerque Transit Department who were also using CNG vehicles; and (5) Provide another fueling facility accessible to the general public.

    Work under this project has ultimately focused on the development of a modular packed bed based thermal energy storage system. The design assumes the use of standard segments of carbon steel pipe filled with spherical materials creating a packed bed. These materials are assumed to be manufactured in such a way that the spherical shape is uniform throughout the packed bed. Out of 32 candidate materials evaluated, 8 materials remain. Each material meets the Phase I milestones that were specified for this storage system: a round trip efficiency in excess of 93%, and a required volume of packed bed material that does not exceed the volume of molten salt used in a two-tank storage system with equivalent thermal performance.

    This project was very successful in terms of providing a unique source of information for rural communities and landowners. We are very pleased with the overall results and believe that this is a vital program for the sustainable development of wind energy. The outreach materials created by Windustry are filling a serious void in information about how local communities and rural landowners can participate in wind development projects. In our program implementation we learned how great the demand is for this type of information both through our hotline calls and website usage. We also realized that the materials require constant updating and maintenance. There is a balance that needs to be found in printing the materials to have handouts ready at meetings for our primary target audience and more research and revisions for the website materials. All of this work is of an ongoing nature. Since this funding was awarded for one year, Windustry will be seeking other funding sources to continue the work in future years. Below is a summary of the Windustry accomplishments as well a sampling of website usage reports. Windustry is appreciative of the US DOE for its support of this wind energy industry work and the Wind Powering America initiative.

    An investigation was made to determine if corn stalks could be economically collected for use in the production of either structural or insulation board. An assessment of the research shows that a pressed corn board suitable for some building application can be manufactured from ground corn stalks at very low cost; that an inexhaustible supply of corn stalks are readily available; and that the energy savings of corn board can only be estimated by assessing fuel savings to agriculture, freight savings, increased insulating qualities, manufacturing energy saved, and the potential use of acoustical insulation structural panels used in the prefab industry and/or the mobile home industry.

    The genome of Rhodobacter capsulatus has been almost completely sequenced. It consists of a single chromosome containing 3.5 Mb and a circular plasmid of 134 kb. This effort, started in 1992, began with a fine-structure restriction map of an overlapping set of cosmids that covered the genome. Cosmid sequencing led to a gapped genome that was filled by primer walking on the chromosome and by using lambda clones. Methods had to be developed to handle strong stops in the high GC (68%) inserts. Annotation was done with the ERGO system at Integrated Genomics, as was the reconstruction of the cell's metabolism. It was possible to recognize 3709 orfs, of which functional assignments could be made with high confidence to 2392 (65%). Unusual features include the presence of numerous cryptic phage genomes embedded in the chromosome.

We have found that the X-ray emission in the ROSAT energy band comes from a population of compact hard sources (most likely X-ray binaries) and hot diffuse gas with a temperature ranging from a few to ten million K. This gas is spatially-extended on galactic scales and its properties are entirely consistent with theoretical expectations for a starburst-driven superwind. The starbursts studied span a range of roughly 1000 in bolometric luminosity and are hosted by galaxies ranging from dwarfs through L* spirals through ma,ior galactic mergers. The X-ray properties of these o@jecls scale in a natural way with the luminosity of tile starburst: more powerful starbursts are more X-ray luminous and create hot outflowing gas whose energy content is likewise larger.

    This grant provided the basic funding that enabled me to carry out a detailed characterization of the proteins used by the aerobic soil bacterium, Thermobifida fusca, to degrade cellulose and to study the mechanisms used by T. fusca to regulate cellulase synthesis. This work resulted in 53 publications and led to the decision by The DOE Joint Genome Institute to sequence the T. fusca genome. T. fusca is now recognized as one of the best studied cellulolytic microorganisms and our work led to the discovery of a novel class of cellulases, processive endoglucanases, which are found in many cellulolytic bacteria including both aerobes and anaerobes. In addition, we were able to determine the mechanism by which Cel9A caused processive hydrolysis of cellulose. This research also helped to explain why many cellulolytic microorganisms produce two different exocellulases, as we showed that these enzymes have different specificities, with one attacking the reducing end of a cellulose chain and the other attacking the nonreducing end. Our work also provided additional evidence for the importance of a cellulose binding domain (carbohydrate binding module) [CBM] in the hydrolysis of crystalline cellulose.

    This collaborative research project between Georgia State University (Prof. Elliott) and Oklahoma University (Profs. Elmore and Engle) is aimed at understanding further the measurement of the timing of geologic processes causing diagenetic events (e.g. burial metamorphism, thrust sheet burial, basinwide fluid migration, contact metamorphism) through combined application of paleomagnetic analyses and K-Ar age determination of illite. These diagnenetic events are known to heat rocks to temperatures sufficient to form crude oil and natural gas. Thus, improved knowledge of the timing of diagenetic events lead to improved burial history models for the exploration of crude oil and natural gas (e.g. Pevear, 1999). Our principal working hypothesis is that the authigenesis of magnetic mineral phases results also from the conversion of smectite to illite and the ages of these diagenetic events can be constrained by comparing the ages of chemical remanent magnetizations (CRMs) to independently measurements of K-Ar age of diagenetic illite. In this study, we have tested the hypothesized connection between smectite to illite (i.e clay diagenesis) and remagnetization by conducting K-Ar dating of authigenic illites in units in Scotland and Montana (e.g., Elliott et al., 2006a; Elliott et al., 2006b).

    Most prokaryotes of interest to DOE are poorly understood. Even when full genomic sequences are available, the function of only a small number of gene products are clear. The critical question is how to best infer the most probable network architectures in cells that are poorly characterized. The project goal is to create a computational hypothesis testing (CHT) framework that combines large-scale dynamical simulation, a database of bioinformatics-derived probable interactions, and numerical parallel architecture data-fitting routines to explore many “what if ?” hypotheses about the functions of genes and proteins within pathways and their downstream effects on molecular concentration profiles and corresponding phenotypes. From this framework we expect to infer signal transduction pathways and gene expression networks in prokaryotes. Detailed mechanistic models of E. Coli have been developed that directly incorporate DNA sequence information. The CHT framework is implemented in the NIEngine network inference software. NIEngine has been applied to recover gene regulatory networks in E. coli to assess performance. Application to Shewanel la oneidensi and other organism of interest DOE will be conducted in partnership with Jim Collin's Lab at Boston University and other academic partners. The CHT framework has also found broad application in the automated learning of biology for purposes of improving human health.

    The forest products industry consumes large amounts of energy. Understanding how genetic variation in trees actually controls the characteristics of wood, the major raw material utilized by the industry, is an opportunity for energy savings. For companies that are vertically integrated (i.e., have both tree production and processing operations), energy savings can accrue for both production and processing. Tree production demands nitrogen fertilizers, the manufacture of which is highly energy intensive. Wood processing for paper product manufacturing requires digestion and bleaching, both of which are more efficient when the lignin content of wood is reduced. This project identified genes involved in utilization of nitrogen from fertilizer, and the coupling of nitrogen demand to lignin content, establishing a framework for reducing tree nitrogen demand per unit carbon gained. This creates opportunities for genetic manipulation of trees for greater energy efficiency.

    The Georgia Institute of Technology’s Industrial Assessment Center (GT IAC) has a long history working on the IAC program with over 30 years of experience in meeting the IAC program’s goals in a very effective manner since beginning participation in the IAC program’s predecessor, the EADC, in 1977. During the last four year contract period, October 1, 2002 through September 31, 2006, the GT IAC continued this work with the assessments of eighty nine (89) industrial facilities. These assessments resulted in the reported implemented savings of forty eight thousand (48,000,000) kWh of electricity and seven hundred and fifty thousand (750,000) MMBtu of natural gas. The total calculated cost savings from the recommendations implemented was five and a half million dollars ($5,500,000). These savings reoccur annually. However, this cost savings is the total of various recommendations that were calculated during 2002 to 2006. During this time period, energy prices were almost always lower than current energy prices. If you adjust the cost savings number to account for current energy prices, the cost savings would exceed nine million dollars ($9,000,000) reoccurring annually. Beyond the reduction of industrial energy consumption and the cost savings benefit, education has also been an important element of this Center’s work. Primarily this entailed both formal and on the job training of this Center’s student employees. Over the four year time frame, this Center has had fifteen different student employees work for this Center. This Center has also instructed a graduate level senior mechanical engineering class that allowed senior engineering students to conduct IAC assessments under the supervision of IAC staff. This class exposed over one hundred students to industrial energy consumption and energy efficiency. In addition to educating students, the education of plant personnel has also been an important element for this Center. It is believed that this Center has made effective use of IAC program resources by reducing industrial plant energy consumption and cost by helping them become more energy efficient. In turn, this has helped make domestic industry more competitive. This Center has also helped by introducing the next generation of engineers to energy efficiency in the industrial sector.

    The work done with DOE support during this 15 year period was extensive and successful. It is best summarized by the list of 58 publications (below) which reported progress made with DOE support. These are from the grant period and a few more recent reporting on grant research. Mostly these are primary research reports in reviewed journals. There are also, however, many summary reviews in review journals and in scientific monographs, as they also are key places for reporting research progress. What we did during this grant period (and much longer) was to characterize genetic determinants for bacterial resistances to additional toxic heavy metals of DOE concern, through starting with phenotypic properties of the resistant bacteria to DNA sequence determination and characterization of the genes involved. Over the years (and as shown in the list of publications), the toxic metal-forming elements we have studied included Ag, As, Cd, Cr, and Hg. In each case, we started with basically nothing (or very little) known, progressed through quite detailed understanding, until other laboratory groups also became strongly involved in related studies. More recently, with DOE support, we were the first laboratory group in the world to identify genes for bacterial resistance to silver salts (sil genes) and the closely related silver-and-copper resistance genes cus. This was initially reported in detail in Gupta et al. (1999; see publications list below). We also identified the first toxic metal 'gene island' (multiple transcripts and perhaps 25 genes each in need of detailed study) which encodes the subunits of arsenite oxidase (which we called aso; Silver and Phung, 2005; but most other researchers have subsequently settled on aox for the gene mnemonic). Both of these systems were firsts. Now a few years later, a search on GenBank shows that each is now represented by gene families with more than a dozen examples that have been identified and sequenced. Most of the additional representative systems are from total bacterial genomes without specific gene characterization.

    Calabazas Creek Research Inc. (CCR) completed Phase I the development of a 10 MW, 1.3 GHz, annular beam klystron (ABK) for driving advanced accelerators, such as the International Linear Collider (ILC). Through detailed simulations in Phase I, CCR produced a design that meets all of the requirements for ILC. The ABK uses an annular beam to minimize space charge depression and the impedance. This allows the relatively low voltage of 120 kV specified for the International Linear Collider (ILC). Like the sheet beam klystron, the ABK uses a thin beam located close to the drift tube walls; however, it operates with lower risk, single mode cavities. In addition, it is azimuthally symmetric, dramatically reducing design and fabrication costs. It provides the same operating characteristics as a multi-beam klystron, but is far simpler and will be easier and less expensive to fabricate.

    From September 1, 2002, to November 30, 2006, the Industrial Assessment Center (IAC) at the University of Illinois at Chicago (UIC) conducted over 120 industrial assessments across 19 different industry types in five different states. In the 1,000+ assessment recommendations written during the award, the UIC-IAC has written recommendations that, if implemented will save several millions of kilowatt-hours of electricity and several million British thermal units of natural gas annually. Additionally, the UIC-IAC has achieved an overall implementation rate in excess of 50%. During the overall span of the award period, the UIC-IAC has trained over 50 students, nearly 25% of which have remained in the energy field in some way after graduating from the IAC program. UIC-IAC students have received over $23,000 in scholarships in the last two years alone. During the course of the award, the UIC-IAC has made it a priority to incorporate ITP tools and technologies whenever possible. The ITP Best Practices tools have been used on several assessments and introduced to clients. DOE technologies are constantly compared against assessment clients to determine what technologies have reached the stage where they can effectively be introduced into industrial operations. The UIC-IAC has been involved in several projects for the Department of Energy (DOE), including energy assessments of Department of Defense bases and industrial facilities, the Plant Energy Profiler (PEP) tool assessment, and expanding the range of assessments to include large- energy users. Additionally, the UIC-IAC has forged a close relationship with the Midwest CHP Application Center, working to incorporate combined heat and power (CHP) and distributed generation (DG) technologies into industrial plants. The most recent project is the Save Energy Now (SEN) six- and 12-month follow-up surveys being conducted by UIC-IAC students. The SEN surveys are an effort for the DOE to determine the implementation rate of energy efficiency measures identified by Qualified System (QS) specialists throughout the nation. The UIC-IAC has also written several papers highlighting its work in the arena of energy efficiency. Currently, several UIC-IAC students have submitted a paper to the American Council for an Energy-Efficient Economy (ACEEE). This paper has been accepted by ACEEE and will be presented later in 2007.

    Bioremediation of radionuclides and metals in the subsurface necessitate an understanding of the metabolic capacities and interactions of the anaerobic microorganisms that are found there, including members of the sulfate-reducing bacteria (SRB). Genetic investigation into the pathway of reductant flow to U(VI) in the SRB belonging to the genus Desulfovibrio has been the focus of this project. In Dv. desulfuricans strain G20, we confirmed the importance of the tetraheme cytochrome c3 by disruption of the gene encoding that cytochrome, cycA, and demonstrated a decrease in the ability of the mutant (I2) to reduce U(VI). We found that the cytochrome c3 was necessary for electrons from pyruvate to reach sulfate or fumarate as terminal electron acceptors. It was not needed for electrons from lactate to reach sulfate, from which we infer that a different pathway is used for the electrons from these two substrates. Cyrstal structure of the tetraheme cytochrome c3 was obtained and site-directed mutations of the protein indicated a binding site for metals at heme 4 of the structure. Kinetic studies for oxidation of reduced cytochrome c3 with U(VI) or molybdate revealed a preference for U(VI) as a substrate. Evidence for a role for sodium gradients in the energetic scheme for this soil organism was obtained.

    Michigan Technological University has demonstrated major inroads in establishing the viability of utilizing aluminum smelting by-product waste materials in lightweight concrete product applications. The research identified key elements of producing various forms of lightweight concrete products through utilizing various procedures and mixture components with the by-product materials. A process was developed through pilot plant testing that results in additional aluminum recovery at finer sizes, a clean returnable salt product through spray drying technology, and a low-salt-content oxide product with enough aluminum metal content that it can be used to form lightweight cementitious mixtures. Having three distinct products aids in generating favorable process economics. Revenue projections from aluminum recovery and salt recovery are enough to cover processing costs and create a cost-free oxide product to market for lightweight concrete applications. This supply side commercialization strategy offers aluminum by-product recyclers a potentially no cost product, which has been demonstrated through this project to create desirable and marketable lightweight concrete products of various forms. Environmental benefits to the public are tremendous. At best, all dross and salt cake materials have the potential to be completely recycled and utilized. At worst, disposal sites would see a reduced amount of material: a post processed oxide product with little salt and no hydrogen sulfide or ammonia gas generating capability, which, if isolated from high alkali conditions, would pose no reactivity concerns. The US aluminum industry has historically, along with the steel industry, been a leader in recycling metal. The findings from this project, increased metal recovery, improved salt recycling, and demonstrated end uses for oxide residues, will go a long way in helping the aluminum industry obtain 100% material utilization and zero discharge.

    The industrial Assessment Center at the University of Massachusetts completed 83 assessments in this project period, covering all states in New England and the eastern part of New York. The combined energy consumption for these facilities was more than 750,000,000 kWh costing approximately $77,000,000 for electricity and close to 5,600,000 MMBtu for all fossil fuels combined, totaling almost $37,000,000. The average annual energy costs per plant were $1,372,600. We had almost eight recommendations per assessment, and the implemented recommendations alone are saving these facilities on an average $66,500 or almost 5% of their total energy bill. We have organized and participated in sixteen seminars and presentations promoting energy efficiency practices and other DOE tools and programs. Our center developed the Chilled Water System Assessment tool that is part of DOE’s BestPractices Suite of Tools. During this period we had nineteen students in the program. Fifteen were graduate students, and four were undergraduate students. Eleven of them graduated with the Masters of Science degree in mechanical engineering and are working in the energy field, and three are currently in the program. Two undergraduate students were hired by engineering firms that perform energy efficiency services, and one continued his education and is pursuing an advanced engineering degree. We cooperate with the Manufacturing Extension Partnerships and state Energy Offices to provide energy efficiency services to their constituents. As a result of our activities, all our clients requested assessments or were referred to us by one of the state energy offices, the MEP’s or DOE. Our current and former staff members hold 16 Qualified Specialist certificates. Seven of those were awarded to our students while participating in the IAC program. Currently we have three staff members with nine QS certificates and two students with four. Three people from our staff were involved in the DOE’s Save Energy Now program during the first year of program as steam and process heating qualified specialists.

    This grant supported research into uses of the 'Hubble Space Telescope' Guide Star Selection System data base for important astrophysical problems ancillary to HST observations. The initial focus was to use the data to survey the frequency of wide binary stars at high galactic latitude, as a probe of local dark matter. In the course of this work, it was also discovered that the data base could be used for a purpose never envisaged by its designers, namely, detection of proper motions in faint stars. Some further evaluation of this capability supported by the grant led to the discovery of an entirely new class of stellar object, namely the dwarf carbon star. Publications supported by this grant, including both papers in refereed journals, and also two Ph.D. thesis dissertations, are described briefly.

    This document presents an annual report on our long-term R&D grant for development of new technology for future colliders. The organizing theme of our development is to develop a compact high-field collider dipole, utilizing wind-and-react Nb3Sn coil fabrication, stress man-agement, conductor optimization, bladder preload, and flux plate suppression of magnetization multipoles . The development trail for this new technology began over four years ago with the successful testing of TAMU12, a NbTi model in which we put to a first test many of the construction details of the high-field design. We have built TAMU2, a mirror-geometry dipole containing a single coil module of the 3-module set required for the 14 Tesla design. This first Nb3Sn model was built using ITER conductor which carries much less current than high-performance conductor but enables us to prove in practice our reaction bake and impregnation strategies with ‘free’ su-perconductor. TAMU2 has been shipped to LBNL for testing. Work is beginning on the con-struction of TAMU3, which will contain two coil modules of the 14 Tesla design. TAMU3 has a design field of 13.5 Tesla, and will enable us to fully evaluate the issues of stress management that will be important to the full design. With the completion of TAMU2 and the construction of TAMU3 the Texas A&M group ‘comes of age’ in the family of superconducting magnet R&D laboratories. We have completed the phase of developing core technologies and fixtures and entered the phase of building and testing a succession of TAMU3 model dipoles that each build incrementally upon a proven core design. TAMU3 provides a testbed in which we can build a succession of model dipoles in which each new model uses one new winding module coupled with one module from the previ-ous model, and uses all of the same structural elements in successive models. This incremental development should enable us to keep to a minimum the time between the completion and test-ing of successive models. Each new model will incorporate a particular design element that we wish to evaluate: first the basic TAMU3 structure, then substitute one pancake using high-performance superconductor (3,000 A/mm2 @ 12 T, 4.2 K), then substitute one pancake using mixed-strand cable, then insert a steel nose to reduce the peak field in the end region of a single-pancake coil. While we are building and testing this succession of TAMU3 models we will de-velop the tooling and evaluate strategies for flaring the ends of the center double-pancake coil needed for.TAMU4. TAMU4 is a full implementation of the design, culminating in 14 Tesla performance. Pending the proposed increase of budget from the present 3-year-flat budget and providing that the tests of each model dipole do not lead to substantial modifications of the de-sign, the time to build and test each succeeding model could be ~9 months. During the present funding year we made a sequence of innovations that have major poten-tial benefit for the commissioning of LHC, upgrade of its luminosity, and its long-term future: • An electrode assembly, suitable for integration within the existing LHC dipoles, ca-pable of killing the electron cloud effect – an effect that threatens to limit the lumi-nosity that could be attained in LHC; • A Nb3Sn structured cable, which makes it possible to design very high gradient quadrupoles for upgrade of the interaction regions of LHC to enhance its luminosity; • A Nb3Sn/NbTi levitated-pole dipole for use in the D1 bends that combine and sepa-rate the beams at the intersection regions. The levitated-pole design uniquely solves the problems of radiation damage and heating from particles swept from the beam. • A hybrid dipole technology, in which inner windings of Bi-2212 are integrated in a Nb3Sn block-coil dipole to push to 24 Tesla, opening the possibility of a future trip-ler upgrade of LHC .

Plant sizes varied from one building of 30,000 sq ft to 17 buildings of 1.5 million sq ft. The amount of energy savings identified was worth about $34,303,699. Because of the national level Lean Productivity programs at the university, LMU-IAC is unique in its expertise of the impact of Lean productivity on energy savings, which is huge, far exceeding the energy savings from the equipment improvements. Besides energy savings, LMU-IAC promoted the good name of the program and DOE in the local industry, utilities, trade organizations, the vast aerospace industry, educational institutions, and the public. The IAC work resulted in numerous public lectures, a chapter in the Encyclopedia of Industrial Energy, and several journal articles. 37 students, including 8 graduate students have been trained and issued DOE IAC Certificates.

    The objective of this project is to develop a MgB2 superconducting RF (SRF) cavity technology. Compared to the currently-used SRF material niobium, MgB2 has a much higher Tc of 40 K, a lower residual resistivity (< 0.1 µΩcm), and a higher thermodynamic critical field Hc. SRF cavities with MgB2 coatings have the potentials for higher Q, higher gradient, and higher operation temperatures. A MgB2 SRF technology can significantly reduce the operating costs of particle accelerators when these potentials are realized. In this project, we have made significant progresses in the deposition of large-area (2” diameter) MgB2 films for RF characterizations, deposition of MgB2 films on metal substrates including Nb, Mo, Ta, and stainless steel, enhancement of Hc1 with decreasing MgB2 film thickness, fabrication and characterization of MgB2/MgO multilayers, and deposition of MgB2 films of excellent superconducting properties on the wall of a 6-GHz RF cavity.

    This is a collaborative proposal that aims to establish theoretical foundations and computational tools that enable uncertainty quantification (UQ) in tightly coupled atomistic-to-continuum multiscale simulations. The program emphasizes the following three research thrusts: 1. UQ and its propagation in atomistic simulations, whether through intrusive or nonintrusive approaches; 2. Extraction of macroscale observables from atomistic simulations and propagation across scales; and 3. Uncertainty quantification and propagation in continuum simulations for macroscale properties tightly coupled with instantaneous states of the atomistic systems. Thus, the project offers to enable the use of multiscale multiphysics simulations as predictive design tools for complex systems.

    The work under this grant consisted of encouraging community activities for the development of parallel programming patterns. This work was in conjunction with the research performed under the Pmodels award - where research was pursued on the development for new parallel programming models. Work on programming patterns does not have, as a goal, the invention of new technology. Rather, it is about codifying existing practice, so as to provide practitioners with a common language. This facilitates education and communication between practitioners. In addition, it helps in the design of new parallel frameworks and languages. One major issue in their design is expressiveness: To what extent does the language or framework facilitates the expression of common programming patterns. In order to assess expressiveness in any useful way, it is necessary to identify those common patterns.

These two-component signaling proteins were characterized at the genetic, biochemical, and genomic levels. The results generated by our laboratories have provided numerous insights into how Caulobacter cells sense and respond to a myriad of signals. As nearly all bacteria use two-component signaling for cell regulation, the results from this project help to deepen our general understanding of bacterial signal transduction. The tools and approaches developed can be applied to other bacteria. In particular, work from the Laub laboratory now enables the systematic, rational rewiring of two-component signaling proteins, a major advance that stands to impact synthetic biology and the development of biosensors and other designer molecular circuits. Results are summarized from our work. Each section lists publications and publicly-available resources which result from the work described.

    The Center for Advanced Biobased was created with funding supplied by the Department of Energy to study biobased alternatives to petroleum based materials used in the manufacture of foundry sand binders. The project was successful in developing two new biobased polymers that are based on renewable agricultural materials or abundant naturally occurring organic materials. The technology has the potential of replacing large amounts of chemicals produced from oil with environmentally friendly alternatives.

    The Department of Energy’s Industrial Assessment Center at Colorado State University (CSU IAC) has been helping manufacturers in Colorado and the Rocky Mountain region save energy, reduce waste, and save money while helping to produce highly-trained and highly-capable energy engineers since 1984. The most recent four-year contract continues that trend. This contract ran from September 1, 2002 through May 31, 2007 and included assessments conducted from September 1, 2002 through August 31, 2006. During this contract, the CSU IAC served 77 manufacturers in six Rocky Mountain States and recommended about 311,800 MMBtu/yr in energy savings, 12.6 million gallons of waste water reduction per year, nearly 650,000 pounds of solid waste reduction per year, and more than 5,600 gallons of hazardous solid waste per year, saving more than $9.54 million dollars per year in utility, waste disposal, raw material, and labor costs. Total expenditures for the period were about $814,000 for the period or about $203,500 per year. Thus, the CSU IAC generated almost 12 times more recommended cost savings than the project cost. In addition, the program employed 24 undergraduate mechanical and civil engineering students and seven graduate mechanical engineering students. Of these students, more than 75% have gone on to successful careers in energy engineering or manufacturing, where they continue to provide additional energy and cost savings for industry and the country.

    This research effort was directed towards the development of a novel cold-setting adhesive for the manufacture of laminated veneer lumber, LVL. The adhesives studied were isocyanate-reactive polyurethanes that cure at room temperature and bond to high moisture content veneer (12%). The elimination of hot-pressing and the reduction in veneer drying is expected to provide substantial energy savings and decreases in VOC emissions. Furthermore, the use of higher moisture content veneer was expected to reduce or eliminate the tendency for veneer over drying, and the related reduction in wood surface energy. The effort produced a novel emulsion polymer isocyanate (EPI) adhesive that performed better than the standard phenol-formaldehyde adhesive. This performance comparison/evaluation suggested that the new adhesive could perhaps meet the original project goals, stated above. However, this effort was not translated into technological practice, nor evaluated on a larger pilot scale, because the participating companies experienced personnel changes that altered outlook for this technology.

    The best summary of our results is probably provided by the list of publications based on work supported by this grant, which is given below. In general, the objectives were realized, and we have demonstrated, for the first time, that radiolabeled Abs can kill single tumor cells very effectively, and that they can also be effective in treating models of human tumors growing as xenografts in SCID mice. Our original work, as proposed in the application, was with Abs to B-lymphoma cells, namely anti-CD20 and anti-HLA-DR. After our successful efforts with these Abs, we decided to extend the results to other tumor types. Accordingly, carcinomas of the breast, ovary and other tissues were treated with radiolabeled Abs to EGFr and HER-2. These tumors cells were also effectively killed in vitro with radiolabeled Abs. This is significant because these Abs are widely used, and successful, in the clinic (unlabeled) and because the flattened shape of the cells, in vitro, is expected to make them considerably more difficult to kill than the spherical lymphoma cells. A major goal was to compare radionuclides emitting different types of radiation, namely low energy electrons (Auger and conversion electrons), {beta}-particles, and {alpha}-particles. All three types could effectively kill cells in vitro with considerable specificity. However, the low energy electrons, which we abbreviate LEEs, have significant advantages, mainly due to their lower level of non-specific toxicity. This was demonstrated both in vitro and in vivo. Thus, {beta}-particle emitters conjugated to anti-CD20 could protect mice against the growth of B-lymphoma tumor cells, but the therapeutic effect was limited by the maximum dose that could be administered, without killing the mouse. In contrast, the LEE emitters were more effective, largely because the toxicity was much less, allowing an approximately 10-fold higher {mu}Ci dose to be injected. Conjugates with {alpha}-particle emitters were also less effective than the LEE emitters, probably because of the much shorter half-life of the available {alpha}-particle emitter (less than 1 hr). Of the LEE emitters tested, {sup 67}Ga was considerably more potent than {sup 111}In, per decay, but {sup 111}In has major advantages due to the fact that better chelators are available, and the purity of the commercial radionuclide is much higher. Both were better than {sup 125}I because of their more suitable half-lives. Therefore, 111In remains the optimal LEE emitter at the current time, although it is useful to continue to consider the use of other radionuclides. In fact, we have emphasized that there are many LEE-emitting radionuclides that would be much more potent than {sup 111}In; these are not available at all, or not available carrier-free, or suitable conjugation methods have not been developed. Our results indicate that the development of such radionuclides, at the DOE reactors or at other facilities, would be likely to have substantial medical applications. In therapy, we have thus far been able to treat micrometastatic tumors (injected i.v.) and only small s.c. tumors, barely visible by eye, thin disks with a diameter of 1-2 mm. Because some of the tumors used grow slowly, we are able to obtain effective therapy as late as one month after tumor injection. While this is a limitation, perhaps due to the short tissue path-length of the LEEs, it does not mean that they are not clinically useful: many patients have microscope disease, and such tumors are probably the most difficult, and important, to treat. If we can effectively eliminate such micrometastases, there is a prospect of curing patients in whom the tumor would otherwise recur. Also, it is still possible that we could use this approach to treat larger tumor, if multiple doses are administered. It should also be pointed out that my laboratory is virtually the only one doing experiments of this type. Previous theoretical calculations had suggested that it should be possible to kill single cells with Abs conjugated to LEE emitters, and that the level of Ab binding, with high-density antigens, should be sufficient to achieve this effect. But we were the first to put this idea into practice. Therefore, we feel that we have essentially opened up a new area of research, and that future investigators will be able to build on the solid foundation than we have laid.

    This project was designed to develop tools that would permit an accurate assessment of the patient doses that are received in screening mammography, and to subsequently demonstrate those tools to perform an objective evaluation of patient doses. The project also provides an educational component through the integration of multiple aspects of applied radiological engineering to provide students with realistic applications of many of the theoretical principles that are studied as part of their graduate curriculum.

    The Net100 project was motivated by complaints from computational scientists and researchers at DOE laboratories who were frequently unable to transfer data across the country at appropriate available bandwidth rates. Many high-performance distributed computing applications transfer large volumes of data over wide area networks and require data rates on the order of gigabits per second. Even though Internet backbone speeds have increased considerably in recent years, distributed applications are rarely able to take full advantage of these new high-capacity networks. The goal of the Net100 project was to try to improve the network performance of scientific applications without requiring the intervention of a network expert. The main objective was to have the operating system dynamically tune network flows so the application and the scientist would not have to be network-aware. The Net100 project sought to accomplish this by augmenting the tools and technology developed as a part of the NSF-sponsored Web100 project.

    NIST has played a key role in many of the one-on-one, domestic, and international interlaboratory comparisons of measurements on superconductors. The history of interlaboratory comparisons of measurements on superconductors tells us that careful measurement methods are needed to obtain consistent results. Inconsistent results can lead to many problems including: a mistrust of the results of others, unfair advantages in commerce, and erroneous feedback in the optimization of conductor performance. NIST has experience in many interlaboratory comparisons; a long-term commitment to measurement accuracy; and independent, third-party laboratory status. The principal investigator's direct involvement in the measurements and daily supervision of sample mounting is the unique situation that has allowed important discoveries and evolution of our capabilities over the last 30 years. The principal investigator's research and metrology has helped to improve the accuracy of critical-current (I{sub c}) measurements in laboratories throughout the world. As conductors continue to improve and design limits are tested, the continuation of the long-term commitment to measurement accuracy could be vitally important to the success of new conductor development programs. It is extremely important to the U.S. wire manufacturers to get accurate (high certainty) I{sub c} measurements in order to optimize conductor performance. The optimization requires the adjustment of several fabrication parameters (such as reaction time, reaction temperature, conductor design, doping, diffusion barrier, Cu to non-Cu ratio, and twist pitch) based on the I{sub c} measurement of the conductor. If the I{sub c} measurements are made with high variability, it may be unclear whether or not the parameters are being adjusted in the optimal direction or whether or not the conductor meets the target specification. Our metrology is vital to the U.S. wire manufacturers in the highly competitive international arena and to meet the aggressive performance goals. The latest high-performance Nb{sub 3}Sn wires are being designed with higher current densities, larger effective filament diameter, less Cu stabilizer, and, in some cases, larger wire diameters than ever before. In addition, some of the conductor designs and heat treatments cause the residual resistivity ratio (RRR, ratio of room temperature resistivity to the resistivity at 20 K) of the stabilizer to be less than 20. These parameters are pushing the conductors towards less intrinsic stability, into a region we call marginally stable. These parameters also create a whole series of challenges for routine I{sub c} testing on short-samples, even when tested with the sample immersed in liquid helium. High-current, variable-temperature I{sub c} measurements are even more difficult than those made in liquid helium because the sample is only cooled by flowing helium gas. Providing accurate I{sub c} results under these conditions requires a complex system that provide adequate cooling as well as uniform sample temperature. We have been make variable-temperature measurements for about 15 years, but we started to design the first high-current (at least 500 A), variable-temperature, variable-strain apparatus in late 2006. Our first critical-current measurements as a function of strain, temperature, and magnetic field, I{sub c}(B,T,{var_epsilon}), in a new single, unified apparatus (full matrix characterization) were made in the summer of 2008. This is the only such facility in the U.S. and it has some unique components that are not duplicated anywhere in the world. The compounding of all three variables (H, T, {var_epsilon}) makes an already labor and time intensive characterization very formidable; however, the results cannot be generated any other way and are needed to answer key questions about strain and temperature safety margins and about the reliability of using scaling laws based on small data sets to predict performance. In the future, this new apparatus will allow NIST to create a database on strands that would benefit

    Two primary technologies have been employed for analysis and measurement of the Synechocystis proteome. (1) 2D-gel electrophoresis. Currently one of the most reliable options in quantitative proteomics, typical 2D-gel experiments use isoelectric focusing (IEF) in the first dimension. In the case of membrane proteins, detergents must be added to maintain their solubility though only neutral/zwitterionic surfactants are compatible with the IEF process. We have optimized 2D gel separations for Synechocystis proteins extracted and separated into soluble and membrane subfractions. The resolution and coverage of integral membrane proteins is only marginally satisfactory and alternatives to the first dimension are being considered. Size-exclusion chromatography under non-denaturing conditions was one option that was explored but resolution was insufficient for subfractionation of the membrane-bound proteome. A more highly resolving technique, the ''Blue-native gel'' has proven excellent for Synechocystis and we plan to set up this technology in the near future. Proteins with altered expression are being identified through standard LCMSMS technologies. The analysis of PSI, PSII and SDH deficient mutants is completed, establishing the comparative aspect of the project for integration with the ultrastructural and metabolomic experiments at ASU. We are also looking forward to receiving ftsZ and VIPP1 interruption mutants to explore the effects on the proteome of cell enlargement and disruption of thylakoid biogenesis, respectively. (2) 2D liquid chromatography with mass spectrometry of intact proteins. Early experiments with total membrane protein extracts of Synechocystis showed that the spatial resolution of the reverse-phase separation used in front of the mass spectrometer limited detection to the one hundred or so most abundant proteins. The intact mass tags (IMTs) measured in this experiment represent the first of these measurements that will ultimately define the entire proteome. While some of the IMTs were matched to masses calculated from translations of genomic open-reading frames allowing reasonably confident identification of about half of them (hypothetical IMTs), we are currently validating identifications using a combination of peptide mass fingerprinting after cyanogen bromide cleavage and LC-MSMS after trypsin, of protein in fractions collected during LC-MS+. In order to gain more complete proteome coverage we are applying a liquid separation in front of the LC-MS+ experiment. Size-exclusion chromatography is the first separation technology to be employed, yielding immediate benefits, while still not satisfactory for overall resolution of complexes. Total membranes were solubilized with dodecyl maltoside (1.5%) and separated on deactivated silica (G 4000 SW). LC-MS+ analysis of less-retained chlorophyll-containing fractions, using reverse-phase and size-exclusion technologies, yielded intact protein mass spectra of the two large photosystem I subunits PsaA and PsaB as well as many other IMTs (Figures 1 & 2). These integral membrane proteins have eleven transmembrane helices and, at 81 and 83 kDa, represented one of the most significant challenges to the intact protein molecular weight approach. The identities of the proteins were confirmed by peptide mass fingerprinting and while there is good general agreement between measured and calculated masses it is noted that modest post-translational modifications are necessary to account for the measured molecular weights of the intact proteins. Whether these discrepancies are due to genuine post-translational modifications or DNA sequence errors remains to be determined. The data have been published allowing us to claim to be the first to have completed high-resolution electrospray-ionization mass spectrometry of the core subunits of Photosystem II, Photosystem I and the cytochrome b{sub 6}f complex providing effective proof-of-principle for application of the intact mass approach to the integral membrane proteome. Significantly, we reported greater integral membrane prot

    Installation of new Shortwave Spectrometer for permanent operation at SGP - In May 2006 the new ShortWave Spectrometer (SWS) was installed in the Optical Trailer at the Southern Great Plains Central Facility SGP on 27 April 2006. The SWS began full operation 28 April 2006 and has run continuously to the present. Over 25 GB of spectra has been collected, calibrated and archived. 3-D radiative transfer simulations - Retrieved fields of cloud optical thickness and effective radius to from the MODIS Airborne Simulator were used to reproduce 3D cloud fields that were used a input to 3D radiative transfer simulations and then compared with simultaneous Solar Spectral Flux Radiometer (SSFR) spectral irradiance measurements. The influence of both horizontal and vertical cloud structure, using accurate versus approximated optical properties in the radiative transfer model on the modeled irradiance was examined, as was the influence of using the full phase function versus using approximations of single scattering properties. In a related study, cloud microphysical and radiation data from two field experiments were compared measured irradiances with the modeled counterpart, using various 3D cloud models as input for two 3D radiative transfer models. Two papers were published. Direct measurement of aerosol radiative forcing efficiency - The SSFR and the NASA Ames 14-channel Airborne Tracking Sunphotometer (AATS-14) made simultaneous measurements from the Sky Research J-31 aircraft during NEAQS-ITCT, with nineteen missions over the Gulf of Maine between 12 July and 8 August 2004. SSFR and AATS measurements were used to derive the change in net spectral irradiance per change in aerosol optical depth as measured along horizontal flight legs: dF/d(AOD), or aerosol radiative forcing efficiency [W m{sup -2} AOD{sup -1}]. Unlike ground-based measurements of direct aerosol radiative forcing which rely upon the advection of various air masses over a measurement site during an extended period of time, the airborne method has the advantage of being quasi-instantaneous. Ten cases were found to be well suited for analysis using this gradient forcing method, and they exhibited a high degree of variability in the derived aerosol forcing efficiency, likely the result of changing aerosol characteristics with changing airmass during the experimental period. Over the integrated solar spectrum the mean instantaneous forcing was -135 W m{sup -2}. Converting to a 24 hour average, this equates to a forcing efficiency of -83 Wm{sup -2}, a magnitude similar to that observed during INDOEX. Variability among the cases examined was attributed to differences in aerosol single scattering albedo and this quantity was derived for each case based upon best fit between measured and modeled forcing efficiency. The details of this research have been summarized in a paper [Redemann, Pilewskie, et al., 2006].
