Computation of deformation-induced textures in electrodeposited nickel coating

引用

中国有色金属学会会刊：英文版 2006年第B01期16卷 232-238页

作者：龙士国周益春潘勇 Key Laboratory for Advanced Materials and Rheological Properties of Ministry of education Faculty of Material Photoelectron PhysicsXiangtan UniversityXiangtan 411105China

The deformation-induced textures in electrodeposited nickel coating were numerically studied. The finite element method (FEM) for polycrystalline was developed based on Taylor model. Then the deformation-induced textures in electrodeposited nickel coating with initial random and lamellar texture were simulated under tensile load. It is found that the initial textures significantly influence the deformation-induced textures. For nickel coating with the initial random textures, when the tensile strain is about 40%, there are some lamellar textures. For nickel coating with the initial lamellar textures, the lamellar texture is more intensity with the increase of the tensile strain. With the increase of the tensile strain in the coating, there are more pronounced element distortion and a more inhomogeneous deformation. Due to the different crystal orientations, the grain-scale roughness is observed. With increasing tensile strain in the coating, the surface grain-scale roughness increases on the free surface. The surface roughness of the coating with initial random texture is lower than that with the initial lamellar texture.

Kinetic Monte Carlo simulation of growth of BaTiO_3 thin film via pulsed laser deposition

引用

中国有色金属学会会刊：英文版 2007年第6期17卷 1441-1446页

作者：郑学军杨博朱哲吴波毛宇亮 Faculty of Materials and Photoelectronic Physics Xiangtan University

Considering the characteristics of perovskite structure, a kinetic Monte Carlo(KMC) model, in which Born-Mayer- Huggins(BMH) potential was introduced to calculate the interatomic interactions and the bonding ratio was defined to reflect the crystallinity, was developed to simulate the growth of BaTiO3 thin film via pulsed laser deposition(PLD). Not only the atoms deposition and adatoms diffusion, but also the bonding of adatoms were considered distinguishing with the traditional algorithm. The effects of substrate temperature, laser pulse repetition rate and incident kinetic energy on BaTiO3 thin film growth were investigated at submonolayer regime. The results show that the island density decreases and the bonding ratio increases with the increase of substrate temperature from 700 to 850 K. With the laser pulse repetition rate increasing, the island density decreases while the bonding ratio increases. With the incident kinetic energy increasing, the island density decreases except 6.2 eV

Tripartite states Bell-nonlocality sudden death in a quantum-critical environment

引用

Chinese Physics B 2010年第10期19卷 63-67页

作者：张登玉谢利军唐世清詹孝贵陈银花高峰 department of Physics and Electronic Information Science Hengyang Normal University

We demonstrate that multipartite Bell-inequalities violations can be fully destroyed in finite time in three-qubit states under a quantum-critical environment, which is an Ising model in a transverse field. We use the Mermin- Ardehali-Belinksii-Klyshko （MABK） inequality to detect the degree of nonlocality as measured by the extent of their violations. The effects of system-environment couplings, the size of degrees of freedom of environment and the strength of transverse field on the Bell-inequality violations are given for two different initial states, namely, the W class and GHZ class states. The results indicute that the Bell-inequality violations of the tripartite states will be completely destroyed by the decoherence under certain conditions.

Agglomerated Pd Catalysts and Their Applications in Hydrogen Production from Formic Acid Decomposition at Room Temperature

引用

Chemical research in Chinese Universities 2016年第2期32卷 272-277页

作者： LIU Jun LAN Lixin WU Chao LI Rong LIU Xuanyan department of Pharmaceutical and Biological Engineering Hunan Chemical Vocational Technology College Zhuzhou 412004 P. R. China

Agglomerated Pd catalysts with the nano-porous structure were simply prepared by one-step reduction reaction without using any stabilizer. The Pd catalysts show a high catalytic activity for the decomposition of formic acid at room temperature. Among all the Pd catalysts tested, the Pdug catalyst exhibits the highest catalytic activity. Moreover, the breakthrough of the advanced catalysts is that the above agglomerated Pd catalysts can be easily separated from the liquid system to control the catalytic reaction at any time, which may further promote the practical application of formic acid as a H2 storage material.
