Preparation, characterization and photocatalytic properties of nanometer zinc ferriteXiaojun Guo, Youli Qi, Xien Li, Shengyin Li, Wu Yang, and Jinzhang GaoChemistry and Chemical Engineering College... Microscopy). These results showed that the range of particle size of ZnFe2O4 is about 15-25 nm. Photocatalytic activities of nanometer ZnFe2O4 were also evaluated by degradation of the curcumin solution......
PHOTOCATALYTIC PERFORMANCE OF PLASMA SPRAYED TiO2-ZnFe2O4 COATINGS Y.Zeng1,W.J. Qian1,J.H. Gao1,J.T. Liu1 (1.Shanghai Institute of Ceramics, The Chinese Academy of Sciences, Shanghai 200050, China... of plasma sprayed coatings are studied. The photocatalytic efficiency of the as-sprayed coatings is evaluated through the photo mineralization of methylene blue. It was found that TiO2 coatings can......
Fabrication and Characterization of Ni-Al_2O_3 Nano-Composite Coatings by Sediment Co-Deposition () 摘要:Ni-Al_2O_3 nano-composite coatings were fabricated by sediment co-deposition (SCD) from Watt''s type electrolyte containing nano-Al_2O_3 particles without any additives. For comparison, Ni-Al_2O_3 nano-composite coatings were prepared by conventional electro-plating (CEP) under experimental......

selected and put into lubricating oil with nanometer CaCO3 particles. By testing some parameters, such as the maximum non-seizure load, the shape and diameter of wear scar, the friction factor, the nanometer CaCO3 particles'' properties of extreme pressure,anti-wear and friction reduction have been tested and analyzed. The properties of the nanometer CaCO3 particles'' tribology chemistry have......
