Characterisation of Potential Replacements for Nickel Compounds used in Decorative Chromium Plating
The electroplating industries use soluble nickel salts in numerous applications. Over the past few years this has become problematic due to the reclassification of these salts from a harmful substance to now a toxic substance. The introduction of the legislation REACH (Registration, Evaluation, …

Diazine-bridged coordination polymers of copper and nickel : synthesis and thermal, spectral, structural, and magnetic properties
A large number of coordination compounds of copper(I), copper (II) and nickel (II) have been prepared and characterized by thermal, spectroscopic and X-ray diffraction methods as well as by elemental analysis and magnetic susceptibility measurements. The neutral ligands used in the study were …

Bioavailability and toxicity of nickel to freshwater organisms : a modeling approach
… matter) affect the acute and chronic toxicity of nickel to freshwater organisms. For each testing organism (a unicellular green alga, an aquatic invertebrate and a fish) a bioavailability model was developed capable of accurately predicting nickel toxicity in both artificial and natural waters. An …

Kinetics of the ligand exchange reactions between bidentate ligands and rriethylenetetramine nickelate (II) and synthesis of boron (III) subphthalocyanines with various boron substitutions
… and triethylenetetramine nickel (II) were studied spectrophotometrically over the pH range of 5.2 to 8.0 at 25oC. A ternary complex Ni(Trien)(5MP) forms within a few seconds and subsequently reacts with 5MP to form Ni(5MP)3. The reaction is first-order with respect to: …

Binding study of nickel complex to protein by equilibrium dialysis
… active complex among a series of square planar nickel complexes in promoting DNA oxidation. This complex was synthesized and its structure was proven by electrospray mass spectroscopy, H-NMR, and elemental analysis. The H-NMR data also demonstrated that this complex has two vacant coordination …
