In this research, Li1.25Mn0.125Ni0.125Co0.5O2 Nano powders, were synthesized using sol-gel method at different temperatures, lithium nitrate, manganese nickel cobalt nitrate as raw materials. Thermal and thermal gravimetric of TGA/DTA, characterization structure properties samples prepared by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) performed. Also, with scheme, i...

The results of the synthesis PAN/NiO composite fibers by electrospinning method are presented. installation included a rotating drum collector for collecting fibers. Nickel oxide nanoparticles were synthesized solution combustion from nickel nitrate and urea. It was shown that monophase NiO with average particle sizes 154 nm could be this method. investigated X-ray diffraction analysis scanning...

In the title compound, [Ni(C13H17NO3)(C12H8N2)(H2O)]·5H2O, the Ni(II) atom is in a distorted octa-hedral coordination environment provided by the two N atoms of one bidentate phenanthroline ligand and two O atoms and one N atom from a tridentate 2-[(2-hy-droxy-benz-yl)amino]-4-methyl-penta-noic acid (HAMA) ligand and one water mol-ecule. The complex was prepared by the reaction of nickel(II) ni...

A number of biologically active complexes of cobalt(II) and nickel(II) with pyrazinedicarboxaimido derived thienyl and furanyl compounds having the same metal ion but different anions such as sulphate, nitrate, oxalate and acetate have been synthesized and characterized on the basis of their physical, spectral and analytical data. In order to evaluate the role of anions on their antibacterial p...

Biologically active nickel(ll), copper(ll) and zinc(ll) chelates with thiazole-derived nitro- and chlorosalicylaldehyde Schiff-bases having the same metal ion but different anions, e.g. nitrate, sulfate, oxalate and acetate have been synthesized and characterized on the basis of their physical, spectral and analytical data. In order to evaluate the possible participating role of anions on the a...
