    CD40-CD154 interactions play an important role in regulating humoral and cell-mediated immune responses. Recently, these interactions have been exploited for the development of therapeutic and preventive treatments. The objective of this study was to test the ability of bovine CD154 to target a plasmid-encoded Ag to CD40-expressing APCs. To achieve this, a plasmid coding for bovine CD154 fused to a truncated secreted form of bovine herpesvirus 1 glycoprotein D (tgD), pSLIAtgD-CD154, was constructed. The chimeric tgD-CD154 was expressed in vitro in COS-7 cells and reacted with both glycoprotein D- and CD154-specific Abs. Both tgD and tgD-CD154 were capable of binding to epithelial cells, whereas only tgD-CD154 bound to B cells. Furthermore, dual-labeling of ovine PBMCs revealed that tgD-CD154 was bound by primarily B cells. The functional integrity of the tgD-CD154 chimera was confirmed by the induction of both IL-4-dependent B cell proliferation and tgD-specific lymphoproliferative responses in vitro. Finally, sheep immunized with pSLIAtgD-CD154 developed a more rapid primary tgD-specific Ab response and a significantly stronger tgD-specific secondary response when compared with animals immunized with pSLIAtgD and control animals. Similarly, virus-neutralizing Ab titers were significantly higher after secondary immunization with pSLIAtgD-CD154. These results demonstrate that using CD154 to target plasmid-expressed Ag can significantly enhance immune responses induced by a DNA vaccine. PMID:12517965

    Emerging evidence suggests that microRNAs (miRs) play critical roles in the development and progression of non-small cell lung cancer (NSCLC). In a previous study, the present authors demonstrated that miR-154 acts as a tumor suppressor in NSCLC; however, its underlying molecular mechanism and target in NSCLC remain poorly understood. In the present study, ectopic expression of miR-154 remarkably suppressed cell migration and invasion in NSCLC cells. Zinc finger E-box binding homeobox 2 (ZEB2) was identified as a direct target of miR-154 in NSCLC cells. Furthermore, overexpression of miR-154 could decrease the expression of ZEB2 at the messenger RNA and protein levels. Ectopic expression of miR-154 also increased the levels of E-cadherin, an epithelial marker, and decreased the levels of vimentin, a mesenchymal marker, which contributed to suppress epithelial-mesenchymal transition (EMT) and to inhibit cell migration and invasion. In addition, downregulation of ZEB2 exerted similar effects to those caused by miR-154 overexpression on NSCLC cell migration and invasion, while upregulation of ZEB2 could significantly reverse the inhibitory effects on migration and invasion caused by miR-154 on NSCLC cells. These findings demonstrated that miR-154 inhibited migration and invasion of NSCLC cells by regulating EMT through targeting ZEB2, suggesting that miR-154 may be a potential anticancer therapeutic target for NSCLC.

    Accumulating evidence suggested that microRNA-154 (miR-154) might play important roles in the development of various cancer types. However, the role of miR-154 in breast cancer progression remains largely unknown. Here, miR-154 expression level was measured via quantitative real-time RT-PCR (qRT-PCR) in 36 pairs of human breast cancer tissues and adjacent normal breast tissues and in a panel of human breast cancer cell lines. Cell proliferation, cycle, migration, and invasion were assessed by CCK8 assay, flow cytometer assay, wound healing assay and transwell invasion assay, respectively. Luciferase reporter assay and Western blot was used to verify E2F transcription factor 5 protein (E2F5) as a novel target gene of miR-154. Our results showed that miR-154 was frequently downregulated in breast cancer tissues and cell lines. Overexpression of miR-154 in MCF-7 cells significantly inhibited cell proliferation, migration, and invasion, and increased cell arrest at G0/G1 stage in vitro. E2F5 was identified as a target of miR-154, and its expression was inversely correlated with miR-154 expression in clinical breast cancer tissues. In addition, downregulation of E2F5 in MCF7 cells had similar effect on cell proliferation, cycle, migration and invasion by miR-154 induced. These findings indicate that miR-154 acts as a tumor suppressor by targeting E2F5, suggesting miR-154 as a potential therapeutic target for the treatment of breast cancer. PMID:27398145

    Ultracold quantum gases with long-rang and anisotropic interactions open the door to new possibilities for exploring correlated many-body systems. The advantage of using ultracold atoms in order to realize such systems relies on the high level of control and manipulation offered by this field. Recent progress in trapping and cooling some Lanthanide atoms with a strong magnetic moment such as Erbium or Dysprosium present an important tool to investigate the dipole-dipole interaction. In particular the dysprosium atom has multiple features that make it an interesting candidate to study such systems. It has the largest magnetic moment among all atoms (10μB) and a rich energy level structure which allows the implementation of different cooling schemes. In my talk I will present our experiment with the bosonic isotope 164 Dy. I will set forth the interesting features of Dysprosium and explain the difference with alkali systems. UQUAM

    The collisional magnetic reorientation rate constant g{sub R} is measured for magnetically trapped atomic dysprosium (Dy), an atom with large magnetic dipole moments. Using buffer gas cooling with cold helium, large numbers (>10{sup 11}) of Dy are loaded into a magnetic trap and the buffer gas is subsequently removed. The decay of the trapped sample is governed by collisional reorientation of the atomic magnetic moments. We find g{sub R}=1.9{+-}0.5x10{sup -11} cm{sup 3} s{sup -1} at 390 mK. We also measure the magnetic reorientation rate constant of holmium (Ho), another highly magnetic atom, and find g{sub R}=5{+-}2x10{sup -12} cm{sup 3} s{sup -1} at 690 mK. The Zeeman relaxation rates of these atoms are greater than expected for the magnetic dipole-dipole interaction, suggesting that another mechanism, such as an anisotropic electrostatic interaction, is responsible. Comparison with estimated elastic collision rates suggests that Dy is a poor candidate for evaporative cooling in a magnetic trap.

    Boron-coated dysprosium/dysprosium oxide, carbon-coated dysprosium/DyC{sub 2}, and dysprosium oxide-coated dysprosium nanocapsules were prepared using an arc discharge method in diborane, methane, and argon, respectively. The magnetization of these nanocapsules has been measured at temperatures between 4 and 290 K, in applied fields up to 6 T. The transition temperature of nanocrystalline Dy from the helical phase to the ferromagnetic phase is much lower than that of bulk Dy. The linear temperature dependence of the inverse susceptibility of these nanocapsules, being a mixture of superparamagnetic Dy and paramagnetic dysprosium oxide or carbide, can be explained within the molecular field theory with magnetic moments with the total angular momentum J=15/2 and the Lande factor g=4/3. We discuss the relations between the structure and the magnetization of these nanocapsules.

    Mechanical stress is a well-acknowledged positive regulatory factor for osteogenic differentiation of adipose- derived mesenchymal stem cells (ADSCs). However, the molecular mechanisms associated with micro-RNAs (miRNAs) whereby ADSCs respond to mechanical stimuli remain elusive. We investigated the mechanism of mechanotransduction from the miRNA perspective in the osteogenic differentiation of ADSCs under tensile stress. Microarray analysis showed that miR-154-5p was remarkably downregulated when ADSCs were subjected to mechanical tension. Bioinformatics analysis with luciferase reporter assays demonstrated that Wnt11 3'UTR was a new direct target of miR-154-5p. Under tensile stress, lentivirus-mediated gain- or loss-of-function studies revealed that forced expression of miR-154-5p inhibited osteogenic differentiation of ADSCs, whereas inhibition of endogenous miR-154-5p with its antisense oligonucleotide (ASO-154-5p) obviously promoted osteogenic differentiation. Furthermore, miR-154-5p overexpression decreased activity of the non-canonical Wnt/PCP (RhoA-ROCK) pathway, as indicated by lower expression of Wnt11, active RhoA and ROCKII in miR-154-5p-treated ADSCs. By contrast, miR-154-5p inhibition activated the Wnt/PCP signals. Taken together, these results demonstrate that, under tensile stress, miR-154-5p negatively regulates ADSCs osteogenic differentiation through the Wnt/PCP pathway by directly targeting Wnt11. This novel regulatory pathway provides new insights into the molecular mechanism of mechanotransduction in osteogenic differentiation of ADSCs. PMID:25959411

    A lidar instrument was developed to make simultaneous measurements at three distinct wavelengths in the visible and near infrared at 0.532, 1.064, and 1.54 mum with high cross-sectional calibration accuracy. Aerosol and cloud backscatter cross sections were acquired during November and December 1989 and May and June 1990 by the NASA DC-8 aircraft as part of the Global Backscatter Experiment. The instrument, methodology, and measurement results are described. A Nd:YAG laser produced 1.064- and 0.532-mum energy. The 1.54-mum transmitted pulse was generated by Raman-shifted downconversion of the 1.064-mum pulse through a Raman cell pressured with methane gas. The lidar could be pointed in the nadir or zenith direction from the aircraft. A hard-target-based calibration procedure was used to obtain the ratio of the system calibration between the three wavelengths, and the absolute calibration was referenced to the 0.532-mum lidar molecular backscatter cross section for the clearest scattering regions. From the relative wavelength calibration, the aerosol backscatter cross sections at the longer wavelengths are resolved for values as small as 1% of the molecular cross section. Backscatter measurement accuracies are better than 10(-9) (m sr)(-1) at 1.064 and 1.54 mum. Results from the Pacific Ocean region of the multiwavelength backscatter dependence are presented. Results show extensive structure and variation for the aerosol cross sections. The range of observed aerosol cross section is over 4 orders of magnitude, from less than 10(-9) (m sr)(-1) to greater than 10(-5) (m sr)(-1). PMID:18253366

    Transition protein 2 (TNP2) participates in removing nucleohistones and the initial condensation of spermatid nucleus during spermiogenesis. This study investigated the relationship between the variants of the bovine TNP2 gene and the semen quality traits of Chinese Holstein bulls. We detected three single nucleotide polymorphisms (SNPs) of the TNP2 gene in 392 Chinese Holstein bulls, namely, g.269 G>A (exon 1), g.480 C>T (intron 1), and g.1536 C>T (3′-UTR). Association analysis showed that the semen quality traits of the Chinese Holstein bulls was significantly affected by the three SNPs. The bulls with the haplotypic combinations H6H4, H6H6, and H6H8 had higher initial semen motility than those with the H7H8 and H8H4 haplotypic combinations (P<0.05). SNPs in the microRNA (miRNA) binding region of the TNP2 gene 3′-UTR may have contributed to the phenotypic differences. The phenotypic differences are caused by the altered expression of the miRNAs and their targets. Bioinformatics analysis predicted that the g.1536 C>T site in the TNP2 3′-UTR is located in the bta-miR-154 binding region. The quantitative real-time polymerase chain reaction results showed that the TNP2 mRNA relative expression in bulls with the CT and CC genotypes was significantly higher than those with the TT genotype (P<0.05) in the g.1536 C>T site. The luciferase assay also indicated that bta-miR-154 directly targets TNP2 in a murine Leydig cell tumor cell line. The SNP g.1536 C>T in the TNP2 3′-UTR, which altered the binding of TNP2 with bta-miR-154, was found to be associated with the semen quality traits of Chinese Holstein bulls. PMID:24416221

    Excitation functions for shell-stabilized evaporation residues produced in Ca48-induced reactions with Gd154,Tb159,Dy162, and Ho165 targets have been measured in experiments performed at the Cyclotron Institute at Texas A&M University. The examined energy range predominantly covers the 3n and 4n evaporation channels with higher cross sections measured for the 4n products. The σ4n are nearly invariant within experimental uncertainty in reactions with Tb159,Dy162, and Ho165 with the maxima at 12.6 ± 1.9, 12.6 ± 1.7, and 9.4 ± 1.3 mb, respectively. For the reaction with Gd154, the maximum is slightly lower at 4.0 ± 0.6 mb. A simple model to describe the measured production cross sections was employed. Capture was estimated by using the "diffused barrier formula" from the "fusion by diffusion" model proposed by Świątecki et al. [Phys. Rev. C 71, 014602 (2005)]., 10.1103/PhysRevC.71.014602 The fusion probability was estimated by using a phenomenological expression presented by Siwek-Wilczyńska et al. [Int. J. Mod. Phys. E 17, 12 (2008)]., 10.1142/S0218301308009501 The survival probability was calculated according to the formula of Vandenbosch and Huizenga [Nuclear Fission (Academic, New York, 1973)], derived from transition-state theory. The best agreement is reached between calculation and experiment upon inclusion of collective effects in the calculation of the survival probability, shown previously to be important for production of weakly deformed nuclei. This, in turn, challenges the expectation that strong shell stabilization benefits the production cross section. The present data are compared with earlier studies on production of neutron-deficient nuclei in Ca-induced reactions with lanthanide targets.

    Dysprosium oxide and dysprosium-oxide-doped titanium oxide thin films were grown by atomic layer deposition on silicon substrates. For depositing dysprosium and titanium oxides Dy(thd){sub 3}-O{sub 3} and TiCl{sub 4}-O{sub 3} were used as precursors combinations. Appropriate parameters for Dy(thd){sub 3}-O{sub 3} growth process were obtained by using a quartz crystal microbalance system. The Dy{sub 2}O{sub 3} films were deposited on planar substrates and on three-dimensional substrates with aspect ratio 1:20. The Dy/Ti ratio of Dy{sub 2}O{sub 3}-doped TiO{sub 2} films deposited on a planar silicon substrate ranged from 0.04 to 0.06. Magnetometry studies revealed that saturation of magnetization could not be observed in planar Dy{sub 2}O{sub 3} films, but it was observable in Dy{sub 2}O{sub 3} films on 3D substrates and in doped TiO{sub 2} films with a Dy/Ti atomic ratio of 0.06. The latter films exhibited saturation magnetization 10{sup −6} A cm{sup 2} and coercivity 11 kA/m at room temperature.

    We theoretically study dynamic scalar polarizabilities of the ground and select long-lived excited states of dysprosium, a highly magnetic atom recently laser cooled and trapped. We demonstrate that there is a set of magic wavelengths of the unpolarized lattice laser field for each pair of states, which includes the ground state and one of these excited states. At these wavelengths, the energy shift due to laser field is the same for both states, which can be useful for resolved sideband cooling on narrow transitions and precision spectroscopy. We present an analytical formula that, near resonances, allows for the determination of approximate values of the magic wavelengths without calculating the dynamic polarizabilities of the excited states.

    A magnetotrasnport and magnetization study has been performed in order to probe the changes in the magnetic states of the rare earth element Dysprosium. Primarily there are three magnetic states present in this element in different temperature regions; one changing at Neel temperature (TN ~ 180K) via second order phase transition and another at Curie temperature (TC ~ 90K) via first order magnetic phase transition (FOMT). These two transitions merge at the magnetic field above 1.5T. The first derivative of resistivity indicates the possibility of spin fluctuation above first order phase transition in the spiral antiferromagnetic phase. The magnetoresistance up to 8T reveals distinct features in the para, antiferromagnetic spiral and ferromagnetic regions.

    Radiotherapy treatments with high-energy (>8 MeV) photon beams are a standard procedure in clinical practice, given the skin and near-target volumes sparing effect, the accurate penetration and the uniform spatial dose distribution. On the other hand, despite these advantages, neutrons may be produced via the photo-nuclear (γ,n) reactions of the high-energy photons with the high-Z materials in the accelerator head, in the treatment room and in the patient, resulting in an unwanted dose contribution which is of concern, given its potential to induce secondary cancers, and which has to be monitored. This work presents the design and the test of a portable Dysprosium dosimeter to be used during clinical treatments to estimate the "in vivo" dose to the patient. The dosimeter has been characterized and validated with tissue-equivalent phantom studies with a Varian Clinical iX 18 MV photon beam, before using it with a group of patients treated at the S. Anna Hospital in Como. The working principle of the dosimeter together with the readout chain and the results in terms of delivered dose are presented.

    A search for double β decay of dysprosium was realized for the first time with the help of an ultra-low background HP Ge γ detector. After 2512 h of data taking with a 322 g sample of dysprosium oxide limits on double beta processes in 156Dy and 158Dy have been established on the level of T⩾10-10 yr. Possible resonant double electron captures in 156Dy and 158Dy were restricted on a similar level. As a by-product of the experiment we have measured the radioactive contamination of the Dy 2O 3 sample and set limits on the α decay of dysprosium isotopes to the excited levels of daughter nuclei as T⩾10-10 yr.

Branching ratios to metastable states are demonstrated to be <5x10{sup -4}. A scheme for enhancement of the nonzero-nuclear-spin-isotope cooling and a method for direct identification of possible trap states are proposed.

    Belatacept blocks CD28-mediated T-cell costimulation and prevents renal transplant rejection. Understanding T-cell subset sensitivity to belatacept may identify cellular markers for immunosuppression failure to better guide treatment selection. Here, we evaluate the belatacept sensitivity of allo-antigen-specific CD154-expressing-T-cells, whose T-cytotoxic memory (TcM) subset predicts rejection with high sensitivity after non-renal transplantation. The belatacept concentration associated with half-maximal reduction (EC50) of CD154 expression was calculated for 36 T-cell subsets defined by combinations of T-helper (Th), Tc, T-memory and CD28 receptors, following allostimulation of peripheral blood leukocytes from 20 normal healthy subjects. Subsets were ranked by median EC50, and by whether subset EC50 was correlated with and therefore could be represented by the frequency of other subsets. No single subset frequency emerged as the significant correlate of EC50 for a given subset. Most (n = 25) T-cell subsets were sensitive to belatacept. Less sensitive subsets demonstrated a memory phenotype and absence of CD28 receptor. Potential drug-resistance markers for future validation include the low frequency highly differentiated, Th-memory-CD28-negative T-cells with the highest median EC50, and the least differentiated, high-frequency Tc subset, with the most CD28-negative T-cells, the third highest median EC50, and significant correlations with frequencies of the highest number of CD28-negative and memory subsets.

    Disprosium titanate is an attractive control rod material for the thermal neutron reactors. Its main advantages are: insignificant swelling, no out-gassing under neutron irradiation, rather high neutron efficiency, a high melting point (˜1870°C), non-interaction with the cladding at temperatures above 1000°C, simple fabrication and easily reprocessed non-radioactive waste. It can be used in control rods as pellets and powder. The disprosium titanate control rods have worked off in the MIR reactor for 17 years, in VVER-1000 - for 4 years without any operating problems. After post-irradiation examinations this type of control rod having high lifetime was recommended for the VVER and RBMK. The paper presents the examination results of absorber element dummies containing dysprosium titanate, irradiated in the SM reactor to the neutron fluence of 3.4×10 22 cm -2 ( E>0.1 MeV) and, also, the data on structure, thermal-physical properties of dysprosium titanate, efficiency of dysprosium titanate control rods.

    We present a magnetization and neutron-diffraction study of the basal plane magnetic structure of Dy epitaxial films and Dy/Er superlattices. The thermal evolution of the magnetic phases, the stability of the helical phase under a magnetic field, the thermal variation of the dysprosium in-plane and {ital c} parameters, and of the dysprosium turn angle are successively shown. In Dy/Er superlattices, the dysprosium helix propagates coherently through paramagnetic erbium; at low temperature, individual dysprosium layers undergo a ferromagnetic transition and are coupled antiferromagnetically to each other for erbium layers thicknesses larger than 20 A. In dysprosium films, as expected from the epitaxy effect, the Curie temperature of dysprosium is reduced if dysprosium is grown on yttrium and increased if it is grown on erbium, whereas it is unexpectedly close to the bulk value in Dy/Er superlattices. This amazing value of the Curie temperature in superlattices is correlated to two main experimentally observed effects: (i) the magnetoelastic driving force is reduced compared to bulk dysprosium because of the clamped {gamma} distortion; (ii) the difference between the exchange energies in the helical and the ferromagnetic phases is increased compared to the bulk value. {copyright} {ital 1996 The American Physical Society.}

    The rare-earth element dysprosium (Dy) is an important additive that increases the magnetocrystalline anisotropy of neodymium magnets and additionally prevents from demagnetizing at high temperatures. Therefore, it is one of the most important elements for high-tech industries and is mainly used in permanent magnetic applications, for example in electric vehicles, industrial motors and direct-drive wind turbines. In an effort to develop a more efficient electrochemical technique for depositing Dy on Nd-magnets in contrast to commonly used costly physical vapor deposition, we investigated the electrochemical behavior of dysprosium(iii) trifluoromethanesulfonate in a custom-made guanidinium-based room-temperature ionic liquid (RTIL). We first examined the electrodeposition of Dy on an Au(111) model electrode. The investigation was carried out by means of cyclic voltammetry (CV) and X-ray photoelectron spectroscopy (XPS). The initial stages of metal deposition were followed by in situ scanning tunneling microscopy (STM). CV measurements revealed a large cathodic reduction peak, which corresponds to the growth of monoatomic high islands, based on STM images taken during the initial stages of deposition. XPS identified these deposited islands as dysprosium. A similar reduction peak was also observed on an Nd-Fe-B substrate, and positively identified as deposited Dy using XPS. Finally, we varied the concentration of the Dy precursor, electrolyte flow and temperature during Dy deposition and demonstrated that each of these parameters could be used to increase the thickness of the Dy deposit, suggesting that these parameters could be tuned simultaneously in a temperature-controlled flow cell to enhance the thickness of the Dy layer.The rare-earth element dysprosium (Dy) is an important additive that increases the magnetocrystalline anisotropy of neodymium magnets and additionally prevents from demagnetizing at high temperatures.

    The phase compositions of solid Mg-Sm-Dy alloys corresponding to the magnesium-corner region of the phase diagram are studied by optical and scanning electron microscopy, electrical resistivity measurements, and electron microprobe analysis. The obtained results allowed us to determine the joint solubility of samarium and dysprosium in solid magnesium at 500, 400, and 300°C; it decreases with decreasing temperature. The magnesium solid solution is found to be in equilibrium only with the Mg41Sm5 and Mg24Dy5 compounds, which are in equilibrium with the magnesium solid solution in the binary Mg-Sm and Mg-Dy systems.

    Fluorescent, excitation, and absorption spectra of DyF3 are reported. The energies of the electronic states of the ground level are significantly shifted compared to those of the dilute system DyxLa1-xF3 and are consistent with recent specific heat measurements from 5 to 350 K. The fluorescent decay rate K of the (4F9/2)1 state follows the equation K(μs-1)=1.600+0.0307 T(K), where T(K) is the absolute temperature. At 0 K the quantum efficiency is approximately 4.5×10-4. The decay rate is determined by the donor-to-acceptor transfer rate, where an acceptor is a pair of coupled dysprosium ions which deactivate the (4F9/2)1 state. Cross relaxation of the form 4F9/2+6H15/2→6F3/2+6H5/2 is calculated to be the dominant dipole-dipole decay channel. Comparison of high-resolution absorption line shapes, measured above 4.2 K, and below the ferromagnetic transition 2.53 K shows a shift of the line centers, and a reduction, by a factor of 6 in the linewidths. These results are consistent with analogous measurements performed on the Ising antiferromagnet dysprosium aluminum garnet and reflect the short-range order of the system.

    The influence of dysprosium doping on the photoelectric and luminescent properties of AgCl crystals is studied by methods of microwave photoconductivity and photoluminescence. Doping affects both the loss kinetics of photogenerated electrons and luminescence spectra and parameters of photostimulated burst of luminescence. It is shown that the charged [Dy{sub Ag}{sup {center_dot}{center_dot}} {center_dot} V Prime {sub Ag}]{sup {center_dot}} or neutral [Dy{sub Ag}{sup {center_dot}{center_dot}} {center_dot} 2V Prime {sub Ag}]{sup x} complexes are responsible for a new luminescence band peaked at 470 nm, which manifests itself at weight concentrations of the doping additive >10{sup -6}%. The long-wavelength shoulder at 570 nm in the photoluminescence spectra is attributed to intracenter transitions in the Dy{sup 3+} ions. The rate constant of the reaction of electron capture into the traps forming upon introduction of the dopant, k{sub t} = (3-5) Multiplication-Sign 10{sup -8} cm{sup 3} s{sup -1}, is evaluated. It is assumed that the traps are Dy{sup 3+} dysprosium ions.

    163,164Dy nuclei have been measured by use of the Oslo method on data from pick-up (3He,α) and inelastic scattering (3He,3He') reactions, respectively. The level densities for these dysprosium isotopes together with previously measured 160-162Dy are extracted in the region below the neutron binding energy. Thermodynamic properties are deduced within both micro-canonical and canonical ensemble theories. A phase transition from the pair-correlated state at low energies to a less correlated or uncorrelated state is studied in both ensembles. It is investigated whether the temperature of the nucleus is constant or a varying function of excitation energy. It is found that above an excitation energy of 3 MeV the temperature of all five dysprosium nuclei have a constant value within the experimental uncertainties. The impact of a constant-temperature level density versus a Fermi gas level density is discussed with respect to the canonical heat capacity.

    Ultracold collisions can often be characterized by a single parameter, the s-wave scattering length a, but despite the simplicity of this model, the scattering length a often must be determined experimentally, even for alkali atoms. For highly magnetic lanthanide atoms such as dysprosium (Dy, 10 μB), the dipolar interaction may strongly affect the scattering properties and must also be taken into account. We have characterized the elastic cross-section for scattering between ultracold Dy atoms by measuring the rethermalization rate in a Dy clouds driven out of equilibrium. The experimental data agree well with numerical simulations based on Boltzmann equations that include the dipolar interaction contribution. Our recent work on observations of inelastic dipolar scattering will also be briefly discussed.

    Configuration interaction method is used to calculate transition amplitudes and other properties of the low states of dysprosium which are used in cooling and in the study of the time variation of the fine structure constant and violation of fundamental symmetries. The branching ratio for the cooling state to decay to states other than ground states is found to be smaller than 10{sup -4}. The matrix element of the weak interaction between degenerate states at E=19797.96 cm{sup -1} is about 4 Hz which is consistent with the experimental limit |H{sub W}|=|2.3{+-}2.9(stat.){+-}0.7(syst.)| Hz [A. T. Nguyen, D. Budker, D. DeMille, and M. Zolotorev, Phys. Rev. A 56, 3453 (1997)] and points to feasibility of its experimental measurement. Applications include the search for physics beyond the standard model using the parity nonconservation (PNC) isotopic chain approach.

    Polycrystalline dysprosium oxide is a candidate arc tube material for advanced metal halide lamps because of high transparency, low thermodynamic driving potentials for corrosion and reaction with the salt fills, satisfactory mechanical strength and resistance to thermal shock. This material is cubic and can be polished to achieve higher in-line transmittance than the conventional polycrystalline alumina arc tubes. Rare-earth halide fills, glass frit seals and niobium leads were used in the construction of the Dy2O3 lamps. The experimental lamps exhibited a colour temperature of ~2500 K and CRI of ~90 with rapid warm-up behaviour. The transparent Dy2O3 ceramic offers opportunities to push the limit of ceramic envelopes for improved discharge lamps.

    A new family of pentadecanuclear coordination cluster compounds (from now on simply referred to as clusters) [{Ln15 (OH)20 (PepCO2 )10 (DBM)10 Cl}Cl4 ] (PepCO2 =2-[{3-(((tert-butoxycarbonyl)amino)methyl)benzyl}amino]acetate, DBM=dibenzoylmethanide) with Ln=Y and Dy was obtained by using the cell-penetrating peptoid (CPPo) monomer PepCO2 H and dibenzoylmethane (DBMH) as supporting ligands. The combination of an inorganic cluster core with an organic cell-penetrating peptoid in the coordination sphere resulted in a core component {Ln15 (μ3 -OH)20 Cl}(24+) (Ln=Y, Dy), which consists of five vertex-sharing heterocubane {Ln4 (μ3 -OH)4 }(8+) units that assemble to give a pentagonal cyclic structure with one Cl atom located in the middle of the pentagon. The solid-state structures of both clusters were established by single-crystal X-ray crystallography. MS (ESI) experiments suggest that the cluster core is robust and maintained in solution. Pulsed gradient spin echo (PGSE) NMR diffusion measurements were carried out on the diamagnetic yttrium compound and confirmed the stability of the cluster in its dicationic form [{Y15 (μ3 -OH)20 (PepCO2 )10 (DBM)10 Cl}Cl2 ](2+) . The investigation of both static (dc) and dynamic (ac) magnetic properties in the dysprosium cluster revealed a slow relaxation of magnetization, indicative of single-molecule magnet (SMM) behavior below 8 K. Furthermore, the χT product as a function of temperature for the dysprosium cluster gave evidence that this is a ferromagnetically coupled compound below 11 K. PMID:25483296

    Lanthanide compounds show much higher energy barriers to magnetic relaxation than 3d-block compounds, and this has led to speculation that they could be used in molecular spintronic devices. Prototype molecular spin valves and molecular transistors have been reported, with remarkable experiments showing the influence of nuclear hyperfine coupling on transport properties. Modelling magnetic data measured on lanthanides is always complicated due to the strong spin-orbit coupling and subtle crystal field effects observed for the 4f-ions; this problem becomes still more challenging when interactions between lanthanide ions are also important. Such interactions have been shown to hinder and enhance magnetic relaxation in different examples, hence understanding their nature is vital. Here we are able to measure directly the interaction between two dysprosium(III) ions through multi-frequency electron paramagnetic resonance spectroscopy and other techniques, and explain how this influences the dynamic magnetic behaviour of the system.

    The compression behavior of elemental dysprosium in the hcp- and the Sm-type phases has been examined under hydrostatic pressure. Sm-type Dy has been found about 1% denser than the hcp phase. This increase in density is due to c-axis contraction in Sm-type Dy, whereas the a-axis even expands compared with the hcp-phase. Both the hcp- and the Sm-type phases show an inversion in the pressure derivative of the c/a ratio. For hcp-Dy this inversion is very sharp with minimal c/a at 2.5 GPa. At the same pressure, the compression behavior of hcp-Dy changes abruptly from dominantly c-axis compression to almost isotropic compression with slightly softer S{sub 11}. The bulk modulus increases at this point by a factor of {approx}2. Both hcp- and Sm-type Dy exhibit a crossover from highly anisotropic compression mostly along the c-axis to almost isotropic compression. We discuss these anomalies with respect to a possible Lifshitz transition and structural soft modes.

    With one of the highest intrinsic magnetic moments (10.6 μB/atom ) among the heavy rare-earth elements, dysprosium exhibits a rich magnetic phase diagram, including several modulated magnetic phases. Aided by the Ruderman-Kittel-Kasuya-Yosida interaction, the magnetic modulations propagate coherently over a long range. Neutron diffraction experiments were performed to determine the microscopic magnetic origin of the field induced phases in bulk Dy as a function of temperature, covering regions of the well-known ferromagnetic, helical antiferromagnetic, fan phases, and several possible new phases suggested by previous studies. A short-range ordered fan phase was identified as the intermediate state between ferromagnetism and long-range ordered fan. In a field of 1 T applied along the a axis, the temperature range of a coexisting helix/fan phase was determined. The magnetic phase diagram of Dy was thus refined to include the detailed magnetic origin and the associated phase boundaries. Based on the period of the magnetic modulation and the average magnetization, the evolution of the spin arrangement upon heating was derived quantitatively for the modulated magnetic phases.

  17. Molecular beam epitaxy growth and characterization of dysprosium phosphide and dysprosium arsenide in gallium arsenide and gallium phosphide

    NASA Astrophysics Data System (ADS)

    Lee, Paul Piyawong

    The ability to grow thermally stable Schottky/ohmic contacts and buried, epitaxial metallic or semimetallic layers on semiconductors has many potential applications in novel device structures. Many rare earth group-V compounds with the sodium chloride structure possess the properties that make them potential candidates for stable contacts, buried layers, and other applications. In this work, two novel rare earth compounds, namely dysprosium phosphide (DyP) and dysprosium arsenide (DyAs) have been studied for high temperature ohmic/Schottky contacts to III-V semiconductors as well as for buried metal layers in semiconductor/metal/semiconductor structures. DyP and DyAs have been grown by molecular beam epitaxy on GaAs and GaP substrates. Both DyP and DyAs display metallic behavior and have room temperature resistivities of 8 x 10--5 and 1 x 10--4 Ocm, respectively. The electron concentrations for DyP and DyAs are about 4 x 1020 and 1 x 1021 cm--3, respectively. High quality DyP films as determined by XRD, AFM, and TEM can be achieved at a wide range of substrate temperatures (500°C to 600°C) with excess phosphorus pressure. Unlike most rare earth-group V compounds, DyP films are stable in air with no sign of oxidation. DyP films deposited on n-type GaAs and GaP exhibit Schottky behavior with room temperature barrier heights of 0.83 and 0.90 eV, respectively, with ideality factors close to unity and low reverse bias leakage current densities. These contacts are stable up to 250°C and 350°C for GaAs and GaP, respectively. DyAs films on the other hand, oxidize in air and display weak Schottky behavior on n-type GaAs. DyP has been grown as buried layers in both GaAs/DyP/GaAs and GaAs/DyP/GaP structures. Although high quality DyP layers have been achieved, the GaAs overlayers contain defects such as twins. The poor wetting of GaAs on DyP and the crystal symmetry between the two materials are responsible for the three-dimensional growth and the defects found in the Ga

  18. A Low-Symmetry Dysprosium Metallocene Single-Molecule Magnet with a High Anisotropy Barrier.

    The single-molecule magnet (SMM) properties of the isocarbonyl-ligated dysprosium metallocene [Cp*2 Dy{μ-(OC)2 FeCp}]2 (1Dy ), which contains a rhombus-shaped Dy2 Fe2 core, are described. Combining a strong axial [Cp*](-) ligand field with a weak equatorial field consisting of the isocarbonyl ligands leads to an anisotropy barrier of 662 cm(-1) in zero applied field. The dominant thermal relaxation pathways in 1Dy involves at least the fourth-excited Kramers doublet, thus demonstrating that prominent SMM behavior can be observed for dysprosium in low-symmetry environments.

    Dysprosium (Dy), one of the heavy rare earth elements, is used mainly as an additive for NdFeB permanent magnets which are installed in various modern industrial products such as voice coil motors in computers, factory automation machinery, hybrid and electric vehicles, home electronics, and wind turbine, to improve heat resistance of the magnets. Dy has been produced about 2,000t per year from the ores from ion adsorption type deposits in southern China. However, the produced amount of Dy was significantly reduced in 2011 in China due to reservation of heavy rare earth resources and protection of natural environment, resulting in soaring of Dy price in the world. In order to respond the increasing demand of Dy, unconventional supply sources are inevitably developed, in addition to heavy rare earth enriched ion adsorption type deposits outside China. Heavy rare earth elements including Dy are dominantly hosted in xenotime, fergusonite, zircon, eudialyte, keiviite, kainosite, iimoriite, etc. Concentration of xenotime is found in placer deposits in Malaysia and India, hydrothermal deposits associated with unconformity-type uranium mineralization (Athabasca basin in Canada, Western Australia), iron-oxide fluorite mineralization (South Africa) and Sn-bearing alkaline granite (Brazil). Zircon and fergusontie concentration is found as igneous and hydrothermal products in peralkaline syenite, alkaline granite and pegmatite (e.g., Nechalacho in Canada). Eudialyte concentration is found in some peralkaline syenite bodies in Greenland, Canada, Sweden and Russia. Among these sources, large Dy resources are estimated in the deposits hosted in peralkaline rocks (Nechalacho: 79,000t, Kvanefjeld: 49,000t, Norra Karr: 15,700t, etc.) compared to the present demand of Dy. Thus, Dy will be supplied from the deposits associated with peralkaline and alkaline deposits in future instead of ion adsorption type deposits in southern China.

    Undoped and dysprosium doped lithium borate glass system with empirical formula (70-x) B2O3-30 Li2O-(x) Dy2O3 (x=0.1, 0.3, 0.5, 0.7, 1.0 mol%) were prepared using the melt-quenching technique. The dosimetric measurements were performed by irradiating the samples to 6 MV photon beam using linear accelerator (LINAC) over a dose range of 0.5-5.0 Gy. The glass series of dysprosium doped lithium borate glass produced the best thermoluminescence (TL) glow curve with the highest intensity peak from sample with 1.0 mol% Dy2O3 concentration. Minimum detectable dose was detected at 2.24 mGy, good linearity of regression coefficient, high reproducibility and high sensitivity compared to the undoped glass are from 1.0 mol% dysprosium doped lithium borate glass. The results indicated that the series of dysprosium doped lithium glasses have a great potential to be considered as a thermoluminescence dosimetry (TLD).
