Heteropoly acid promoted nanoparticle of nickel oxide samples were prepared by sol-gel method using heteropoly acids. Prepared composite was characterized by XRD, FT-IR and ICP technique. In this work, we have reported bromination of phenol, its derivatives and some aromatic compounds. The liquid phase bromination of phenol was Performed using heteropoly acids immobilized nanoparticle of nickel...

Dye photodegradation using ozone and Nickel ferrite nanoparticle (NFN) as a photocatalyst was studied. The catalyst was synthesized and characterized by FT-IR, SEM and XRD. Textile dyes including Remazol Red RB (RRRB) and Direct Green B (DGB) were degraded as model compounds. Dye degradation was investigated using UV–Vis and ion chromatography (IC) analyses. The effect of catalyst dosage, pH, s...

Potential applications of nickel nanoparticles demand the synthesis of self-protected nickel nanoparticles by different synthesis techniques. A novel and simple technique for the synthesis of self-protected nickel nanoparticles is realized by the inter-matrix synthesis of nickel nanoparticles by cation exchange reduction in two types of resins. Two different polymer templates namely strongly ac...

The potential of Pleurotus ostreatus spent mushroom compost (PSMC) as a green biosorbent for nickel (II) biosorption was investigated in this study. A novel approach of using the half-saturation concentration of biosorbent to rapidly determine the uptake, kinetics and mechanism of biosorption was employed together with cost per unit uptake analysis to determine the potential of this biosorbent....

BACKGROUND Corrosion resistance is an important requirement for orthodontic appliances. Nickel and chromium may be released from orthodontic wires and can cause allergic reactions and cytotoxicity when patients use various mouthwashes to whiten their teeth. Our study aimed to assess the release of nickel and chromium ions from nickel titanium (NiTi) and stainless steel (SS) orthodontic wires fo...

The published crystal structure in the paper by Zibaseresht & Hartshorn (2006) is almost certainly that of the nickel complex and not the copper complex as originally identified. Refinement of the copper occupancy was consistent with the presence of a lighter transition metal ion in the structure, and residuals improved significantly when the complex was refined as the nickel or cobalt salts. U...

The extraction of nickel(II) from aqueous hydrochloric acid solution by I-phenyl 3-methyl-4-benzoylpyrazol-5-one (PMBP-OH) dissolved in carbon tetrachloride has been studied. The extraction of nickel(II) from the aqueous solution in the range of 1.0-5.0 M hydrogen ion concentration has been found to be much higher compared to that of cobalt(II). The extraction of nickel with PMBPOH is simple, f...

Dinuclear Nickel(II) Complex, Binucleating Ligand The asymmetric unit of crystal of the title compound, [Ni2(L)(C3H 3N2)j (L = 1,3-Bis(2hydroxy-4-methoxybenzylideneamino)propan-2-ol, C3H 3N 2 = pyrazolate) contains two inde­ pendent dinickel(II) complexes. In both molecules, the nickel(II) ions are bridged by the alkoxo group of the ligand and the N atoms of the pyrazolate group. Each nickel(II...

Ultrasonic velocities and densities have been measured for the aqueous solution of manganese sulphate, nickel sulphate and copper sulphate in polyvinyl alcohol solution, in different concentration at 303K. Adiabatic compressibility, intermolecular free length, acoustic impedance, surface tension and other acoustical parameters have been calculated to assess the polymer-ion interaction. It is se...
