[ 1 ] - 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...
[ 2 ] - Effect of Chelating Agent on Morphology and Phase Evolution of Spinel Nanoparticles Synthesized via Sol-Gel Method
The purpose of this study was to evaluate the effect of glycyrol (tri-dentate, GLY) and ethylenediamine (double- dentate clay, en) chelating agents on phase and morphology changes of spinel nanoparticles synthesized by sol-gel method. Characterization of samples was performed by X-ray diffraction (XRD) and field-emission scanning electron microscope (FESEM) equipped with energy dispersive X-ray...
[ 3 ] - Effect of Neodymium Dopping on Morphology, Phase and Magnetic Properties of Ni0.7Zn0.3NdxFe2-xO4 Ferrite Nanoparticles Synthesized by Complexing Sol-Gel Method
The purpose of this study was to evaluate phase changes and magnetic properties of neodymium doped Ni0.7Zn0.3NdxFe2-xO4 (x = 0, 0.01, 0.03, 0.05, 0.07, 0.10) nanoparticles synthesized by complexing sol-gel method. In this method, triethanolamine (TEA) acted as both a gelling agent and a chelating agent. Samples were characterized by X-ray diffraction (XRD) analysis, field emission scanning elec...
[ 4 ] - 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),...
[ 5 ] - COMPARISON OF MICROSTRUCTURE AND PHASE EVOLUTION OF YSZ NANOPARTICLES SYNTHESIZED BY CO-PRECIPITATION AND MOLTEN SALT METHODS
This study aimed to compare the phase changes and morphology of yttria-stabilized zirconium oxide powders (YSZ) synthesized by co-precipitation and molten salt methods. Ammonia precipitating agent was used for the synthesis of YSZ powder by co-precipitation method and a mixture of sodium carbonate and potassium carbonate salts was used as a molten salt in the molten salt method. Samples were ch...
