zinc oxide (zno) nanopowders were synthesized by the sol–gel method from an ethanol solution of zinc sulfate heptahydrate in the presence of diethylene glycol surfactant. detailed structural and microstructural investigations were carried out using x-ray diffraction (xrd), high-resolution transmission electron microscopy (hrtem), field emission scanning electron microscopy (fe-sem), fourier tra...

in this research iron manganese oxide nanocomposites were prepared by co-precipitation, sol-gel and mechanochemical methods by using iron (iii) nitrate, iron (ii) sulfate and manganese (ii) nitrate as starting materials. these nanocomposites were prepared in the presence of various catalyst beds. the polyvinyl pyrrolidon (pvp) was used as a capping agent to control the agglomeration of the nano...

The CuNiCA nanopanicles have been synthesized by sol-gel auto-combusson. microwave and co-precipitationtechniques. Then, the results of the three techniques were compared. In the vol-ael auto-combustion synthesiswas used glycine as a fuel. At first, sol was prepared. Then, gel was achieved from drying so'. The prepared gelwas burnt at 350°C. In the noicrowavc technique, gel was prepared. Then, ...

in this paper, indium tin oxide (ito) nanoparticles has been prepared by chemical methods under given conditions with solution of indium chloride (incl3·4h2o), tin chloride (sncl4·5h2o) in ammonia solution. the samples were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem) analyses after heat treatments. the sem results showed that, the size of the ito particles pr...

Tin oxide nanoparticles have been prepared by conventional sol-gel technique. Research grade tin chloride (SnCl2.2H2O) was used as tin and zinc sources. Ethylene glycol and alcohol were used as solvents under different synthesis conditions. Transparent un-doped SnO2 sol was prepared after continuous stirring and refluxing at 40C. Thin films, prepared from SnO2 sol, have also been deposited on g...

in this research, a sol-modified composite electrodeposition technique that combines the sol-gel method with the conventional electrodeposition process was utilized to deposit ni-tio2 nanocomposite coatings. cyclic voltammetry and chronoamperometry techniques were applied to study the influence of the tio2 sol concentration on the deposits’ electrochemical behavior. the results clearly showed t...

Sn-doped Zinc oxide is experimented in this research work using sol-gel method. The sol is here constructed using the zinc-acetate dehydrate and tin chloride. Once the solution is prepared, the analysis is performed for XRD patterns at different temperature values. The intensity analysis is been performed for different annealing temperatures at different wavelength. The results show that as the...

Objective(s): A simple and "green" method was developed for preparing zinc oxide nanoparticles (ZnO-NPs) in aqueous starch solutions. Starch was used as a stabilizer to control of the mobility of zinc cations and then control growth of ZnO-NPs prepared via a sol-gel method. Because of the special structure of the starch, it permits termination of the particle growth.Materials and Methods: The d...
