Catalytic performance for methane combustion of supported Mn-Ce mixed oxides士丽敏1,储伟1,瞿芬芬2,胡金燕2,李民敏11. School of Chemical Engineering, Sichuan University2. Department of Environment, Sichuan... dispersion of active components or formation of solid solution between manganese and cerium oxides in the bulk and on the surface of mixed oxide catalysts. The reducibility was remarka-bly promoted......
Blue-Light Emission from Undoped and Rare Earth-Doped Wide Bandgap Oxides Hao Jianhua1,Wu Rui2,Huang Xiongwu2,He Guogen2 (1.Department of Optoelectronic Engineering, Huazhong University of Science...-emitting properties of phosphors are discussed. In addition, novel blue-light emission was observed in certain typical undoped wide bandgap oxides. The luminescence of the oxides depends on the growth......
fracture mode of rare earth oxides doped alumina ceramics exhibited obvious transgranular fractures as well as intergranular fracture.The results of research show that the improvement of bending strength and fracture toughness of alumina ceramics with rare earth oxides was achieved by refining the grain size and strengthening the grain boundary.关键词:......
