Preparation of mixed rare earths modified chitosan for fluoride adsorption梁鹏,张艺,汪东风,徐莹,罗斓College of Food Science and Engineering, Ocean University of China摘 要:This paper described the fluoride removal from water using a new adsorbent namely mixed rare earths modified chitosan (CR). Mixed rare earths mainly contained La followed by Ce which was analyzed......
Rare Earths, Niobium and Tantalum Minerals in Bayan Obo Ore Deposit and Discussion on Their Genesis 张培善1,宋仁奎1,陶克捷1,杨学明1,杨主明1 (1.Institute of Geology and Geophysics, Chinese Academy of Sciences.... It is obviously that some minerals are strata minerals and some are post-strata minerals. The rare earths, niobium and tantalum minerals are exactly the post-strata minerals. In these minerals......
Effect of Rare Earths on Electronic Structure of (110) Twin Martensite Boundary for Ni2MnGa Alloy Wang Jiannong1,Fei Yanqiong2,Wan Jianfeng1 (1.School of Materials Science and Engineering, Shanghai...-Mn-Ga alloy; rare earths; [全文内容正在添加中] ......
:Photoluminescent(PL) and cathodoluminescent(CL) properties of rare earths (Sc3+, La3+, Gd3+ and Lu3+) doped (Y0.97Tb0.03)2SiO5 were studied. Rare earth doping clearly influences PL and CL properties... the color saturation, whereas Lu3+ doping decreases the color saturation. CL measurements show that CL intensity increases for all rare earths doped systems. The energy transfer from Gd3+ to Tb3......
