The reaction between Ni(II), Co(II), cr(III) bitrates, Ni(II) chloride and ambidentate a-keto ylide benzoylmethylenetriphenylphosphine (BPPY) resulted in isolation of [Ni(BPPY)2](NO3)2.2H2O, [Ni(BPPY)2]Cl2, [Co(BPPY)2](NO3)2 and [Cr(BPPY)3](NO<sub...

We have investigated Mn, Co and Ni substitution effects on polycrystalline samples of LaFePO0.95F0.05 by resistivity and magnetoresistance measurements. In LaFe1-xMxPO0.95F0.05 (M = Mn, Co and Ni), the superconducting transition temperature (Tc) monotonously decreases with increasing the impurity doping level of x. There is a clear difference of Tc suppression rates among Mn, Co and Ni doping c...

Nanowire is a cylindrical nano-structure with nanometer dimensions. In this research, the studied nanowire was made from the magnetic triple Ni-Fe-Co alloy.&#10 We utilized ordered porous anodic aluminum oxide as a template for the nanowire deposition. The nanowire arrays were electrodeposited in the cylindrical pores of the oxide layer by AC potential in a simple sulfate bath. Then the relatio...

The catalytic performance of Ni-Al, Mg-Al, and Co-Ni LDHs as novel nanocatalysts was evaluated in the oxidation of toluene. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). The XRD and FTIR approved the structure and functional groups of the LDH, respectively. Also, the presence of cations with dif...

in this research, polyvinylchloride based composite heterogeneous cation exchange membranes were prepared by the solution casting technique. chitosan-co-iron nickel oxide nanoparticles were utilized as membrane surface modifier to improve the membranes electrochemical properties. the effect of additive nanoparticle concentration in the modifier solution on the properties of composite membranes ...

4(4-nitrophenyl-zao)-2-(2-methoxy phenimino)-phenol and its coordination compounds with ni(ii), cu(ii), co(ii) and fe(iii) have been synthesized and characterized by elemental analyses, ft-ir, far-ir, near ir, uv-vis, mass spectrometry and molar conductivity and their electrochemical behaviours are reported.

Ni nanoparticles supported on ZrO2 are a prototypical system for reforming catalysis converting methane to synthesis gas. Herein, we examine this catalyst on a fundamental level using a 2-fold approach employing industrial-grade catalysts as well as surface science based model catalysts. In both cases we examine the atomic (HRTEM/XRD/LEED) and electronic (XPS) structure, as well as the adsorpti...
