Trans. Nonferrous Met. Soc. China 25(2015) 1248-1253 Selective oxidation of methane to syngas using Pr0.7Zr0.3O2-δ: Stability of oxygen carrier Yun-peng DU1,2,3, Xing ZHU1,2,3, Hua WANG1,2,3, Yong... selectivity in the range of 83.5%-88.1%. Though Pr-Zr solid solution possessed high thermal stability, lattice oxygen was obviously reduced for the recycled sample due to decreased surface oxygen which......
Photocatalytic activity of CuO towards HER in catalyst from oxalic acid solution under simulated sunlight irradiation YAO Mao-hai(姚茂海)1, TANG You-gen(唐有根)1, ZHANG Li(张 丽)2, YANG Hai-hua(杨海华)1... concentration, and Ag loading content on the photocatalytic activity of the as-obtained CuO sample were investigated. The results show that the as-obtained CuO exhibits high activity for photocatalysis of H2......
Effect of heat treatment on microstructure and dimensional stability of ZL114A aluminum alloy JIANG Long-tao(姜龙涛), WU Gao-hui(武高辉), YANG Wen-shu(杨文澍), ZHAO Yong-gang(赵永刚), LIU Shan-shan(刘珊珊... on microstructure, micro-yield strength and dynamic dimensional stability of ZL114A aluminum alloy were investigated by optical microscopy (OM), transmission electron microscopy (TEM), tensile testing......

Detailed string stability analysis for bi-directional optimal velocity modelZHENG Liang(郑亮) (School of Traffic & Transportation Engineering, Central South University, Changsha 410075, China... vehicle technologies. Its combined string stability condition can be obtained through the method of the ring-road based string stability analysis. However, the partial string stability about traffic......
photocatalytic degradation processes both technically and economically[2,3]. Therefore, it is important to study and evaluate the fixing stability of deposited TiO2 film on the substrate, which...: The immobilized photocatalyst, TiO2 film supported on activated carbon fibers (TiO2/ACFs) prepared with molecular adsorption-deposition (MAD), exhibits high stability in cyclic photodegradation runs......

J. Cent. South Univ. Technol. (2011) 18: 2085-2090 DOI: 10.1007/s11771-011-0947-4 Pseudo-dynamic analysis of overturning stability of retaining wall WANG Kui-hua(王奎华), MA Shao-jun(马少俊), WU Wen-bing(吴... Heidelberg 2011 Abstract: A new method was presented to determine the safety factor of wall stability against overturning based on pseudo-dynamic approach. In this time-dependent method, the actual dynamic......
Numerical analysis of stability for mined-out area in multi-field couplingLuo Zhou-quan(罗周全)1, XIE Cheng-yu(谢承煜)1, ZHOU Ji-ming(周吉明)1, JIA Nan(贾楠)1, Liu Xiao-ming(刘晓明)1, 2, XU Hai(徐海)1(1. School... of stability for goaf, if it was analyzed as regular 3d mined-out area and the influence of coupling stress-seepage-disturbance was not considered adequately. Taking a lead zinc mine as the background......
