A comparative study on the growth and characterization of nonlinear optical amino acid crystals: L-alanine (LA) and L-alanine alaninium nitrate (LAAN).
2008-01-03

A comparative study on the properties of L-alanine and LAAN crystals has been made and discussed. It may be concluded that the protonation of the amino group in the L-alanine molecule is the key factor in increasing the relative SHG efficiency of LAAN. The protonation is justified by the crystal structure analysis, FTIR and photoluminescence studies. The ...

Impacts of mechanistic changes on HOx formation and recycling in the oxidation of isoprene
2010-09-01

Recently reported model-measurement discrepancies for the concentrations of the HOx radical species (OH and HO2) in locations characterized by high emission rates of isoprene have indicated possible deficiencies in the representation of OH recycling and formation in isoprene mechanisms currently employed in numerical models; particularly at low levels of NOx. Using version 3.1 of the Master ...

The mid-infrared spectra of seven very large PAHs (VLPAHs), with C number ranging from 54 to 130, have been determined computationally using Density Functional Theory (DFT). Trends in the dominant band positions and intensities for the major PAH bands in the 5 to 9 micron region as a function of PAH size, charge (neutral, cation, and anion forms) and geometry are discussed. The 6.2 micron CC ...

A gyrokinetic theory of turbulent toroidal angular momentum transport as well as modifications to neoclassical poloidal rotation from turbulence is formulated starting from the fundamental six-dimensional kinetic equation. GyroBohm-scaled transport is evaluated from toroidal gyrokinetic simulations using the GYRO code [1]. The simulations quantify the two pinch mechanisms in the radial transport ...

The parallel momentum balance in low pressure tokamak plasma is analyzed in the framework of fluid theory. It is shown that inertial effects and gyroviscosity lead to coupling of parallel momentum balance with fluctuations of electrostatic potential and plasma pressure [1]. Such coupling, mediated by magnetic field curvature, was earlier identified in gyrokinetic theory [2, 3]. Set of evolution ...

The self cleansing capacity of the troposphere and the lifetime of key greenhouse gases are controlled to a large extent by the OH radical. In environments where biogenic VOC emissions are high and NOx concentrations are low, for example in tropical rainforests, the current understanding of tropospheric chemistry suggests that OH radical concentrations should be suppressed.
