[ 1 ] - تولید و ارزیابی پودر کامپوزیتی نانوساختار Cr2O3-Ag در فرایند پاشش پلاسمایی

In plasma sprayed nanostructured composite coatings with ceramic matrix, the feedstock must consist of nanoparticles of appropriate specifications. In this research, the procedure for production of Cr2O3-Ag agglomerated nanostructured composite powder to produce comosite coatings has been investigated. Nanopowders of Cr2O3 with 0, 2, 5, and 10 volume percentages of silver were dispersed to obta...

[ 2 ] - Effect of Calcination Temperature and Li / TFA Molar Ratio on Morphology and Phase of Lithium Fluoride Nanoparticles Produced by Fluorolytic Sol-Gel Method

In this research, synthesis of lithium fluoride (LiF) nanoparticles  by fluorolytic sol-gel method has been studied. Moreover, the effect of lithium ion to fluorine source molar ratio and calcination temperature on particle size and phase of LiF nanoparticles were investigated. Lithium acetate (C2H3LiO2), trifluoroacetic acid (TFA), ethylene glycol monobutyl ether and oleic acid were used as so...

[ 3 ] - Influence of Temperature, Time, pH, Capping Agent Concentration and Zn/Se Molar Ratio on Morphology and Phase Evolution of Zinc Selenide Nanoparticles Synthesized by Hydrothermal Method

The aim of the study was to investigate the effect of temperature, time, pH, capping agent concentration (mercaptoacetic acid), Zn to Se and Se to reducing agent (NaBH4) mole ratios on morphology, phase developments and size of zinc selenide nanoparticles prepared by hydrothermal method. Characterization of zinc selenide nanoparticles was performed by Field Emission Electron Microscopy (FESEM),...
