Study on the cooperativity of hydrogen bonds betweenH₂YandHX(X=F,Cl,Br;Y=O,S,Se)

Journal of Theoretical and Computational Chemistry, 2014
The structure characteristics, interaction energies, cooperative energies of the complexes between chalcogen hydrides ( H2Y ) and halogen hydrides (HX) have been studied theoretically at the MP2 level with aug-cc-pVTZ basis set in this paper. The conclusions show that there are strong interactions between H2Y and HX.

THE EFFECT OF a-SiN:H AND a-Si:H SURFACE ROUGHNESS OF TFT BY PE/RACVD

International Journal of Modern Physics B, 2010
This paper describes the influence of surface roughness on the mobility of a - SiN : H and a - Si : H . For the a - SiN : H deposited by PECVD, the roughness was 0.832 nm. The a - SiN : H layer composed of (PECVD 150 nm + RACVD 100 nm) had better characteristic of roughness than the a - SiN : H layer (PECVD 250 nm) by 47%. The roughness of the a - Si :

DEPOSITION OF M—C (M = Cr, Mn, Fe) FILMS BY MAGNETRON SPUTTERING

Modern Physics Letters B, 2005
Thin films of M — C ( M = Cr , Mn , Fe ) have been deposited on silicon substrates by magnetron sputtering. It was found that interdiffusion between carbide films and silicon substrates occurred for Mn — C/Si and Fe — C/Si samples. The hardness and elastic modulus of the Cr — C films were around 16 ± 1 GPa and 210 ± 21 GPa , respectively.

Second hyperpolarizability of multimetallocenes [Cp–M_n–Cp] of Be, Mg and Ca

Journal of Theoretical and Computational Chemistry, 2015
Multimetallocene complexes ( Cp – M n– Cp ) of Be , Mg and Ca have been considered for the theoretical study of static second hyperpolarizability using a number of DFT functionals. Owing to the cooperative effect in bonding, beryllium forms multiberyllocene complexes ( Cp – Be n– Cp ) which have sufficient thermal stability with respect to ...

REACTIVE RESONANCE AND FORMATION MECHANISM STUDIES OF THE H + NO → N + OH OR O + NH REACTION

Journal of Theoretical and Computational Chemistry, 2006
The partial potential energy surface (PPES) of H + NO → N + OH or O + NH of 3A″ symmetry is first constructed using QCISD (T) method with 6-311++g** basis set, and then we speculate the existence of the scattering resonance states of these reactions.

MEASUREMENT OF R = B(t→Wb)/B(t→Wq) AT DØ

International Journal of Modern Physics A, 2005
A measurement of the ratio of branching fractions, R = B(t→Wb)/B(t→Wq), with q being any quark with I3 = -1/2 and Q = -1/3, is presented. This analysis considers samples of single- and double-tagged lepton+jets events obtained with the DØ detector, corresponding to integrated luminosities of 169 pb-1 and 158 pb-1, respectively in the e+jets and μ+jets

Superconducting Properties of Bi-Sr-Ca-Cu-O Crystallized Glass

International Journal of Modern Physics B, 1999
This paper reports the crystallization and superconducting properties of Bi 4 Sr 3 Ca 3 Cu 4 O x glass-ceramics. The glass was prepared using the conventional melt-quenching method. X-ray diffraction pattern has shown that the annealing at temperature of 800°C converted the glass into glass-ceramics with Bi 2 Sr 2 CaCu 2 O x superconducting phase ...

CALCULATED STRUCTURAL AND ELASTIC PROPERTIES OF M₂InC(M=Sc, Ti, V, Zr, Nb, Hf, Ta)

Modern Physics Letters B, 2008
Using ab initio calculations, we have studied the structural and elastic properties of M 2 InC , with M = Sc , Ti , V , Zr , Nb , Hf and Ta . Geometrical optimization of the unit cell is in agreement with the available experimental data. We have observed a quadratic dependence of the lattice parameters versus the applied pressure.
