In the title compound, [Ni(NCS)2(C5H5N)2] n , the Ni(2+) cation is coordinated by four thio-cyanate anions (μ-1,3) and two pyridine ligands within a slightly distorted octa-hedral configuration. The Ni-N bond lengths to the pyridine rings are 2.1189 (17) and 2.1241 (17) Å, whereas those to the thiocyanate anions are 2.0299 (18) and 2.0359 Å. The Ni-S bond lengths are 2.5357 (6) and 2.5568 (6) Å...

We study Ni 80 Fe 20-based permalloys with the relativistic spin-polarized Korringa-Kohn-Rostoker electronic structure method. Treating the compositional disorder with the coherent potential approximation, we investigate how the magnetocrys-talline anisotropy, K, and magnetostriction, λ, of Ni-rich Ni-Fe alloys vary with the addition of small amounts of non-magnetic transition metals, Cu and Mo...

Chromium (Cr) and nickel (Ni) concentrations were measured in lung tissue from 110 random necropsies by means of atomic absorption spectrometry. The subjects originated from the Ruhr district (Bochum (71 cases) and Dortmund (16 cases) areas), which has been defined as a particular pollution area with locally high Cr and Ni emissions, and from Münster and vicinity (23 cases). The Cr and Ni conce...

Mesoporous alumina catalysts that incorporate nickel (Ni-Alumina) with different Ni/Al molar ratios of 1:2, 1:5 and 1:10 were synthesized by a one-step sol–gel method using lauric acid as a template. The prepared Ni-Alumina catalysts showed a relatively high surface area with a narrow pore size distribution after calcination at 700 ◦C; these effects were independent of the Ni/Al molar ratio. Al...

BACKGROUND This is the first randomized, double-blind, placebo-controlled trial (EUDRACT No. 2009-013923-43) evaluating nickel oral hyposensitizing treatment (NiOHT) in patients with "systemic nickel allergy syndrome" (SNAS), characterized by Ni-allergic contact dermatitis and systemic reactions after eating Ni-rich food. METHODS Adults with positive Ni-patch test, who reported symptoms sugge...

The interaction of formic acid with Ni( 1 lo), Ni( 1 lO)-carbide, Ni( 1 IO)-graphite, and Ni( 1 lO)sulfide surfaces was examined by molecular beam relaxation spectrometry. The apparent firstorder rate constants for the desorption of formic acid (T, < 300°K) were remarkably similar on all of the surfaces studied, suggesting that the low-temperature formic acid adsorption/desorption interactions ...

Au-Ge alloys are promising materials for high-power and high-frequency packaging, and Ni is frequently used as diffusion barriers. This study investigates interfacial reactions in Au-12Ge/Ni joints at 300 °C and 400 °C. For the reactions at 300 °C, typical interfacial morphology was observed and the diffusion path was (Au) + (Ge)/NiGe/Ni5Ge3/Ni. However, an interesting phenomenon--the formation...

Nanoparticulate zero-valent iron (nZVI) rapidly reacts with oxygen to produce strong oxidants capable of transforming organic contaminants in water. However,the low yield of oxidants with respect to the iron added normally limits the application of this system. Bimetallic nickel-iron nanoparticles (nNi-Fe; i.e., Ni-Fe alloy and Ni-coated Fe nanoparticles) exhibited enhanced yields of oxidants c...

This study examines the effects of cyclodextrin (CD) on the photophysical properties of 1,8-naphthalimide (NI) derivatives including NI-linker-phenothiazine (NI-L-PTZ) dyads in a H2O/CH3CN solution (v/v = 9 : 1). Peculiar excimer and exciplex emissions were observed with reference NI and NI-L-PTZ, respectively, in an aqueous environment. The NI-CD complexes exhibited monomeric emission spectral...

Electrocatalytic activity for the hydrogen evolution reaction on Ni–Co–LaNi5 composite electrodes prepared by electrochemical codeposition technique was evaluated. The relationship between the current density for hydrogen evolution reaction and the amount of LaNi5 particles in Ni–Co baths is like the well-known “volcano plot”. The Surface morphology and microstructure of Ni–Co–LaNi5 coatings we...
