hardly be found in the foam samples prepared by counter-gravity infiltration casting. The foam materials exhibit excellent mechanical properties. The void content strongly affects the mechanical properties of aluminum foams. The yield stress and plateau stress significantly increase with the decrease of void content. Raising pre-heating temperature and increasing packing pressure are effective......

(2012) 19: 2425-2433 DOI: 10.1007/s11771-012-1292-y Spectra analysis and O2 evolution for TiO2 photocatalyst compounded with indirect transition semiconductors TONG Hai-xia(童海霞... photocatalysts were analyzed. The photocatalytic activities of the TiO2 photocatalysts were investigated by splitting of water for O2 evolution. The results indicate that the band gaps of WO3......
Deformation behavior and strength evolution of MIM compacts during thermal debinding LIU Xiang-quan(刘相权), LI Yi-min(李益民), YUE Jian-ling(岳建岭), LUO Feng-hua(罗风华) State Key Laboratory of Powder... heating rate may induce deformation defects. It is also indicated that effect of the factors for the deformation defects is different in different debinding stages. The strength evolution......
of photoinduced electrons from holes to achieve stronger photocatalytic activity. The highest photocatalytic oxygen evolution and PL Spectra intensity are achieved. When the concentration of Ta is 1.0%, the O2 evolution speeds are 130.4 and 69.6 umol/(L?h) under UV irradiation and visible radiation, which are 14.6% and 12.1% higher than those before doping, respectively. Key words: rutile titania......
and the particle size of hollow balls, the length of infiltration is getting longer. Besides, along with the increase of the particle size of the hollow ball, the void content decreases. Improving the filling and holding pressure, lengthening the holding time and adding metal Mg are the effective measures to improve infiltration process.Key words:counter-gravity infiltration casting; hollow ball; void......
Harmony search algorithm with differential evolution based control parameter co-evolution and its application in chemical process dynamic optimizationFAN Qin-qin(范勤勤), WANG Xun-hua(王循华), YAN Xue-feng... harmony search algorithm with co-evolutional control parameters (DEHS), applied through differential evolution optimization, is proposed. In DEHS, two control parameters, i.e., harmony memory......
