In this paper, a study on the vibration of thin cylindrical shells made of a functionally gradient material (FGM) composed of stainless steel and nickel is presented. The effects of the FGM configuration are taken into account by studying the frequencies of two FG cylindrical shells. Type I FG cylindrical shell has nickel on its inner surface and stainless steel on its outer surface and Type II...

Mono- and bimetallic complexes of nickel supported by a terphenyl diphosphine have been synthesized. The reported complexes show diverse metal-arene interactions in the solid state. Reactions of an o,o'-biphenyldiyl dinickel complex with CO and dichloroalkanes lead to fluorene derivatives, indicating the formation of carbon-carbon bonds at a bimetallic moiety.

Structural characterization of a nickel aryldiazo complex supported by the bulky 1,2-bis(di-tert-butylphosphino)ethane ligand reveals square-planar Ni geometry and an unusual side-on coordination mode for the N2R moiety, while the related nitrosyl complex displays trigonal-planar geometry at Ni and end-on coordination of the NO ligand.

Linear nickel nitrosyl compounds supported by tridentate nitrogen and selenium ligands, namely the tris(3,5-dimethylpyrazolyl)hydroborato and tris(2-seleno-1-mesitylimidazolyl)hydroborato complexes, [TpMe2]NiNO and [TseMes]NiNO, have been synthesized and structurally characterized by X-ray diffraction. Computational studies demonstrate that the linear nitrosyl ligand behaves as a trivalent X3 l...

Monolithic catalysts derived from in situ supported hydrotalcite-like films on Al wires display high resistance to coke formation and sintering in the dry reforming of methane due to their hierarchical porous structure, well dispersed metallic nickel species, more basic sites and strong metal-support interaction effect.

Nanoparticles of titanium diboride (TiB2) coated with a conductive polymer and subjected to an oxidizing agent was carried out in this research. TiB2 nanoparticles polypyrrole (PPy) were studied using XRD TEM techniques. Nitrogen adsorption desorption properties are covered modified understand better the surface zone, structural features, pore geometries nanoparticles. The water-based hazardous...

An efficient and sustainable d-sorbitol production viad-glucose hydrogenation was achieved over a hydrotalcite-supported nickel phosphide nanoparticle catalyst with stability, high activity reusability.

A series of nickel complexes supported with a tripodal ligand bis(1-methylbenzimidazolyl-2-methyl)amine (L) or bis(1-methylbenzimidazolyl-2-methyl)-10-camphorsulfonamide (L') on a Ni(II) ion were synthesized and fully characterized. The complexes, [LNiCl(micro-Cl)]2.4CH(3)OH (1), [LNi(CH(3)CN)3](ClO4)2.2CH(3)CN (3), and [L2(2)Ni(2)(micro-OAc)3]X (X = Cl- (5) or ClO4- (7)), coordinated with the ...
