Results of the experimental study of boron-doped single-crystal synthetic diamond substrates and thin homoepitaxial diamond films grown on them with the predetermined properties are discussed. The homogeneity of the substrates and films is examined. Diamond detectors based on the grown diamond structures have been pro…
Oxygen diffusion in layered cuprate La 2 SrCu 2 O 6 has been simulated by the molecular dynamics method in the temperature range of 300–2500 K. The lattice is found to transform at temperatures above 1550 K; this transformation is accompanied by a change in the pair correlation functions. The abrupt change in the oxyg…
Article Crystal structure of diaqua-bis(hydrogen 2-propyl-1H-imidazole-4,5-dicarboxylato)calcium(II), Ca(H2O)2(C8H9N2O4)2 was published on March 1, 2010 in the journal Zeitschrift für Kristallographie - New Crystal Structures (volume 225, issue 1).
Methods for the preparation of nanosized alloys from noble metals by decomposition of monomolecular precursors are described, and the results of these studies are reported. Other aspects of the synthesis procedure and properties of bimetallic nanostructures are also considered. Thermolysis of noble metal compounds led…
The luminescent characteristics in developed blue-emitting Bi-activated multicomponent oxide phosphor thin films that are composed of various combinations of La2O3, Y2O3, and Gd2O3 as the host material are investigated; ((La2O3)1−X–(Gd2O3)X):Bi, (Gd2O3)1−Y–(Y2O3)Y):Bi, and ((Y2O3)1−Z–(La2O3)Z):Bi phosphor thin films w…
The reaction of heterobidentate 4-(dimethylamino)phenyldiphenylphosphine with labile cluster Rh 6 (CO) 15 (NCMe) yielding a new monosubstituted cluster Rh 6 (CO) 15 (Ph 2 PC 6 H 4 NMe 2 ) was described. The reactions of the resulting cluster with GaX 3 compounds were studied. The structure of all obtained compounds wa…
Three-dimensional nucleation rates J and induction times τ of glucose isomerase (GI) crystals were measured by counting the number of observable micro crystals with time in situ under high pressure. We also determined the solubility C e under high pressure from the dependence of the growth and dissolution rates of the…
X-ray powder diffraction patterns of BaRu 4 As 12 with synchrotron radiation have been studied at ambient pressure and at high pressures. A crystal structure of BaRu 4 As 12 was refined by the Rietveld analysis of the x-ray powder diffraction data at ambient pressure. The electrical property of BaRu 4 As 12 have been…
Activated carbon fibers(ACFs) were prepared from general pitch-based carbon fiber by steam activation and catalytic activation method, respectively. The surface area and pore structure of the resultant ACFs were analyzed by N2 adsorption, and electrochemical performances as electrodes of super capacitors were characte…
This paper presents the results of unintentionally doped 4H-SiC epilayers grown on n-type Si-faced 4H-SiC substrates with 8° off-axis toward the [11 0] direction by low pressure horizontal hot-wall chemical vapour deposition. Growth temperature and pressure are 1580 °C and 10 4 Pa, respectively. Good surface morpholog…
The synthesis of AlN via self-propagating high-temperature synthesis (SHS) was attempted, using various ratio of Al powder mixed with AlN powder as diluents. Al and AlN powder mixtures with various weight ratios were ignited a nitrogen atmosphere with various amounts of carbon as additives. High crystalline AlN by SHS…
Article Crystal structure of trilithium divanadium(III) borophosphate hydrogenphosphate, Li3V2[BP3O12(OH)][HPO4] was published on March 1, 2010 in the journal Zeitschrift für Kristallographie - New Crystal Structures (volume 225, issue 1).
The precursor [Fe III (L)Cl] (LH 2 = N,N'-bis(2'-hydroxy-3'-X-benzyliden)-1,6-diamino-3-N-hexane) is a high-spin (S = 5/2) complex (with X = -CH 3 , -O-CH 3 ). This precursor is combined with the bridging unit [Sn IV (CN) 4 ] to yield star-shaped pentanuclear clusters, [(L-X-Fe III ) 4 Sn(CN) 4 ]Cl 4 57 Fe-Mössbauer,…
The charge and spin transport properties of a clean TS–N–TS Josephson junction (triplet superconductor-normal metal-triplet superconductor) are studied using the quasiclassical Eilenberger equation for the Green’s function. The effects of the thickness of normal layer between superconductors on the spin and charge cur…
Photo-Carrier Radiometry has been applied to semi-insulating (SI) GaAs wafers. Due to the ultrafast free carrier lifetime, the conventional diffusion based PCR theory was modified to reflect defect induced carrier radiometry. Modulated and spectrally-gated defect luminescence was measured and analyzed using rate-windo…
57 Fe isomer shifts and the electron density on iron nucleus for a range of tetraoxoferrate ions have been analyzed by means of DFT calculations. The bond lengths and the electron density on the nucleus obtained by our calculations substantially corresponded to the known structural and Mössbauer data. For ferrates the…
In this work, iron oxide nanoparticles (~5 nm) embedded in a chitosan polymer film, were synthesized. In order to obtain this nanostructured material, firstly a homogenous film of Fe(II)-chitosan was prepared. The resulting composite film has a thickness of ~140μm. Iron oxide nanoparticles were in-situ synthesized by…
Coupling laser-shock and static-compression techniques allows to generate material conditions unreachable by either single-shock or static technique alone. Static compression experiments on water were performed using a precompression cell for laser-driven shock experiments. The pressure on static compression in this w…
