,Beijing,100088,China) Abstract:The development of rare earths (RE) applications to semiconductor materials and devices is reviewed. The recent advances in RE doped silicon light emitting diodes (LED...; rare earths; [全文内容正在添加中] ......
Fertilizer Catalyst,Fuzhou University,Fuzhou 35002,China) Abstract:Rare earth gangue, which mainly consists of mixtures of fight rare earths such as lanthana, ceda, neodymium oxide and praseo-dymium oxide... iron catalysts with high amount of cobalt. The role of rare earths was owed to their advantages for favoring the deep reduction of the main composite in catalyst, i.e., iron oxide. This finding......
Effect of Rare Earths on Microstructure and Wear Resistance of Electrodeposition Ni-based Metal Composite Coatings陈蓉娜摘 要:Ni/Al2O3 composite coating was prepared by double pulse electrodeposit technique, and microstructure and wear resistance of Ni/Al2O3 composite coating were studied by SEM, TEM and property test. The results show that the distribution......
Electro-catalytic degradation properties of Ti/SnO2–Sb electrodes doped with different rare earthsFu-Liang Zhu1,Yan-Shuang Meng1,Xiu-Yang Huang21. State Key Laboratory of Gansu Advanced Nonferrous... of the electrode can be significantly improved by doping rare earth(RE) ions into the oxide coating of Ti/SnO2–Sb electrode. Ti/SnO2–Sb electrodes doped with different RE elements(Ce, Dy, La, and Eu) were prepared......
