A unique functional electrode made of hierarchal Ni-Mo-S nanosheets with abundant exposed edges anchored on conductive and flexible carbon fiber cloth, referred to as Ni-Mo-S/C, has been developed through a facile biomolecule-assisted hydrothermal method. The incorporation of Ni atoms in Mo-S plays a crucial role in tuning its intrinsic catalytic property by creating substantial defect sites as...

The aim of the present work is to evaluate activation energy (Ea) at different cathodic overpotentials (η) by potentiodynamic tests which were carried out temperatures Ni-based, NiCr-m, and NiCr-p porous electrodes, during alkaline electrolysis processes. On other hand, electrochemical stability electrodes was evaluated cyclic voltammetry after 1000 cycles operation potentiostatic 10 h −1.5 V v...

The three-coordinate imidos (dtbpe)Ni═NR (dtbpe = (t)Bu2PCH2CH2P(t)Bu2, R = 2,6-(i)Pr2C6H3, 2,4,6-Me3C6H2 (Mes), and 1-adamantyl (Ad)), which contain a legitimate Ni-N double bond as well as basic imido nitrogen based on theoretical analysis, readily deprotonate HC≡CPh to form the amide acetylide species (dtbpe)Ni{NH(Ar)}(C≡CPh). In the case of R = 2,6-(i)Pr2C6H3, reductive carbonylation result...

Clethra barbinervis Sieb. et Zucc. accumulates Nickel (Ni) and Cobalt (Co) at high concentrations., We hypothesized that C. barbinervis cannot distinguish between Ni and Co because of the similar chemical properties of these two elements. To confirm this hypothesis and understand the role of these elements in C. barbinervis, we conducted a hydroponic split-root experiment using Ni and Co soluti...

In the title compound, [Ni(C(16)H(8)N(2)O(4))(C(5)H(5)N)(3)]·C(5)H(5)N, the Ni(II) atom is six-coordinated by two O atoms and one N atom from the Schiff base ligand and by three N atoms from three pyridine mol-ecules, forming a distorted octa-hedral geometry. The Ni-O(phenolate) bond [1.9750 (16) Å] is shorter than the Ni-O(carbon-yl) bond [2.0840 (16) Å] and the Ni-N bonds (mean 2.120 Å).

The title compound, [Ni(C(15)H(24)NSi)(2)], is a homoleptic metal-η(3)-aza-allyl centrosymmetric complex containing two aza-allyl ligands bound in an η(3)-manner to an Ni(II) atom located on a center of symmetry. The overall coordination about the Ni(II) atom is square-planar. The C and N atoms of the aza-allyl group are sp(2)-hybridized. The uneven Ni-C and Ni-N distances [2.045 (5)/2.060 (6) ...

Reactions of the anionic gallium(i) heterocycle, [:Ga{[N(Ar)C(H)](2)}](-) (Ar = C(6)H(3)Pr(i)(2)-2,6), with a variety of mono- and bidentate phosphine, tmeda and 1,5-cyclooctadiene (COD) complexes of group 10 metal dichlorides are reported. In most cases, salt elimination occurs, affording either mono(gallyl) complexes, trans-[MCl{Ga{[N(Ar)C(H)](2)}}(PEt(3))(2)] (M = Ni or Pd) and cis-[PtCl{Ga{...

SnAgCu is one of the most promising candidates for lead-free solders to replace conventional eutectic SnPb solders. The effects of solder volume on interfacial reactions and microstructure evolution in Ni/Au-SnAgCu-Ni(P) solder joints have been investigated under soldering and thermal aging conditions. The results show that solder volume has a strong effect on the formation of Au-containing int...

Quasielastic neutron scattering experiments were performed with Na-hectorite, Ni-hectorite, and Sm-hectorite samples in order to find out whether Sm is present in the clay interlayer as a fully hydrated cation (outer-sphere complex), or, as it follows from neutron diffraction data analysis, it is dehydrated and bound to the clay surface (inner-sphere complex). The results obtained for the Sm-he...
