Influence of crystal structure and formation energies of impurities (Mg,Zn and Ca) in zinc blende GaN XIONG Zhi-hua(熊志华), JIANG Feng-yi(江风益), WAN Qi-xin(万齐欣), RAO Jian-ping(饶建平) Research Center... on neutral metal impurities (Mg, Zn and Ca) in zinc blende GaN were studied. Formation energies were calculated for substitution on the gallium site, the nitrogen site and incorporation in the octahedral......
Effect of added cobalt ion on copper electrowinning from sulfate bath using doped polyaniline and Pb-Ag anodes HUANG Hui(黄 惠)1, ZHOU Ji-yu(周继禹)2, GUO Zhong-cheng(郭忠诚)1 1. Faculty... processes in a copper sulfate-sulfuric acid electrolyte. The oxygen-evolution potential for Pani anode is depolarised at lower current densities (≤0.01 A/cm2) and attains saturation at ρ(Co2+)o≈0.789 g/L......
Effect of Y(OH)_3 microparticles on the electrochemical performance of alkaline zinc electrodes ZHANG Hui1,LI Weiping1,LIU Huicong1,ZHU Liqun1 (1.Key Laboratory of Aerospace Materials and Performance Ministry of Education,School of Materials Science and Engineering,Beihang University,Beijing 100191,China) Abstract:This work focused on the zinc powder coated with Y(OH)_3 microparticles by means......
, causing decomposition of aqueous zinc sulfate electrolyte and deposition of metallic zinc onto the cathodes [2]. To guarantee the zinc deposition and achieve the desirable product indicators, high..., the concentrations of zinc ion and sulfate acid in electrolyte solution change gradually in horizontal axis direction. Therefore, we suppose that the electrolyte is well mixed along the longitudinal......
