">In this research, cerium (Ⅲ) nitrate hexahydrate(Ce(N03)3-6H20) and ammonium molybdate tetrahydrate((NH4)6Mo7O24·4H2O) with Ce3+-to-Mo6+ molar ratio of2:3 were dissolved in 40 ml different solvents of deionized......
transfer band. The concentration quenching of Eu3+ emission indicated that energy transfer from Eu3+ to molybdate host existed even at lower Eu3+ concentration. Key words:Eu; X-ray diffraction......
as carrier with an aqueous solution of ammonium molybdate and used for the synthesis of transesterification of dimethyl carbonate (DMC) with phenol. A series of MoO3/SO42--TiO2 catalysts with different......
methods for anodic films on 1070 aluminum alloy was studied. The new process uses chemical treatments in cerium solution and an electrochemical treatment in a molybdate solution. Potentiodynamic... solutions and an electrochemical treatment in a molybdate solution. It was shown that passive layers containing Ce and Mo were formed on the surface of the aluminum alloy, and their corrosion resistance......
of dissolved glucose and ammonium molybdate. The samples were characterized by thermoanalysis, UV-vis diffuse reflectance spectroscopy (UV-vis/DRS), X-ray diffractometry (XRD), nitrogen adsorption... was collected and washed with deionized water and dried at 80 ℃ in air. The amount (5%-15%, molar fraction) of glucose or ammonium molybdate was added into 60 mL of deionized water in a 100 mL autoclave......
nitride silicates and molybdate phosphors are also introduced.Rare-earth-doped oxynitride and silicate green-emitting phosphors have attracted more and more attention because of the wide excitation......
