The U.S. National Toxicology Program has shown clear evidence of carcinogenicity of nickel subsulfide (Ni(3)S(2)) and some evidence of carcinogenicity of NiO (green) in rats. In the present study, DNA damage in cultured cells and in lungs of rats induced by nickel compounds was investigated to clarify the mechanism of nickel carcinogenesis. In cultured HeLa cells, Ni(3)S(2) induced a significan...

8 This paper addresses different techniques for modelling electrochemical energy storage (ES) devices in insular power 9 network applications supported on real data. The first contribution is a comprehensive performance study between a set of 10 competing electrochemical energy storage technologies: Lithium-ion (Li-ion), Nickel–Cadmium (NiCd), Nickel–Metal 11 Hydride (NiMH) and Lead Acid (PbA) ...

Nickel silicide nanoparticles were prepared in situ on carbon nanofibers through pyrolysis of electrospun fibers containing poly(acrylonitrile) (PAN, fiber precursor), silazane (SiCN ceramic and nickel chloride (nickel source). SiCN ceramics produced during the expanded graphitic interlayer spacing facilitated diffusion metal atoms to surfaces, leading formation at a reduced temperature. In add...

In this work, carbon-supported nickel catalysts with different Ni content (1, 2.5, 5, 10, and 20 wt%) were tested in the oxidation of alpha-pinene solvent-free reaction conditions. The process catalyst preparation consisted two stages. first stage, activated carbon from spent coffee grounds was obtained. second active phase form compounds applied using methods: (1) impregnation material salt so...

Abstract The Nickel oxide nanoparticles (NiO NPs) and oxide/Nanoclay nanocomposite (NiO/Nc NC) were synthesized by chemical reduction method used for the photodegradation of Orange II dyes in aqueous solution. samples characterized through SEM, EDX, FTIR TGA. SEM analysis presented that NiO NPs are spherical with irregular shapes sizes. size particles is range 100–400 nm. It was also observed d...
