The synthesis of NiO nanoparticles was done by sol-gel method. Nickel Acetate Tetrahydrate ((CH3COO)2 –Ni·4H2O) was dissolved in ethanol with constant stirring to obtain a clear and light greenish sol. Oxalic acid solution was used to obtain a thick green gel, then dried in an oven to get dried gel and was then grinded into fine powders and calcined for different time periods to obtain nanocrys...

In this research nanoparticles of Nickel (II) Chloride were synthesized and characterized using fourier transform infrared (FT-IR) spectra. Nanoparticles of Nickel (II) Chloride were prepared by using of ball mill device. A ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. In the researc...
