Thermal studies of ammonium-cobalt-nickel phosphates, NH4[Co1−xNixPO4]·H2O

Contrasts in the Crystallization of Nickel and Cobalt Phosphates in Silica Gels

Synthesis and Structural Studies of Nickel ‎Doped Cobalt Ferrite Thin Films

   The growth and structural study of Nickel doped Cobalt ferrite thin films on glass substrate using spray pyrolysis technique have been done. The structural studies confirmed the growth of polycrystalline film having cubic structure with Fd3m space group. The x ray density was found to increase with Ni concentration, where as the reduction, in crystalline size, was found in XRD m...

Dielectric and Optical Band Gap Studies of Nanostructured Manganese Nickel Oxide and Cobalt Nickel Oxide

Nano oxides of Manganese Nickel and Cobalt Nickel were synthesized by chemical coprecipitation method from the reaction of respective metal sulfides of manganese, nickel, cobalt and sodium carbonate using ethylene diamene tetra acetic acid as an effective capping agent. The carbonate precursors were heated at different temperatures so as to form their oxides. Through the X-ray line broadening t...

Nickel and Cobalt Ores: Flotation

Most of the world’s nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently occurs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magnesium (Table 1). The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores ...

Synthesis, Characterization, Electrochemical and Antimicrobial Studies of N4-Macrocycles of Cobalt(II) and Nickel(II) Metal Ions

The precise analysis of redox chemistry of MN4-based macrocyclic complexes is of great importance because of stabilization of unusual oxidation states of metal ions by macrocyclic ligand and thus have various applications in biochemistry, electrochemistry, electrocatalysis, pharmaceuticals etc. In this work, MN4-macrocyclic complexes of Co (II) and Ni(II) transition metal ...
