Sonochemical Synthesis of Nickel Oxide Nano-particle

Nickel oxide (NiO) nanopowder was obtained during a sonochemical method. Nickel hydroxide precursor, prepared by addition of sodium hydroxide (NaOH) to nickel nitrate Ni(NO3)2 solution and vigorously stirring until the pH becomes 7.2. Ultrasounds waves were applied during precipitation period and after drying in oven nanopowder NiO was achieved. Transient and scanning electron microscopy showed...

3D porous nano/micro nickel sulfides with hierarchical structure: controlled synthesis, structure characterization and electrochemical properties.

A series of nickel sulfide nanocrystallines with hierarchical structures was successfully fabricated in situ on a nickel substrate. The nanocrystalline materials with three dimensional (3D) structures were synthesized via self-assembly under moderate conditions, with ethylenediamine and ethylene glycol as the mixed solvents. The structure and morphology of each nickel sulfide could be controlle...

synthesis of amido alkylnaphthols using nano-magnetic particles and surfactants

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

E-effect in Nickel-zinc Ferrites

A study of the dependence of elastic behaviour of polycrystalline mixed Ni-Zn ferrites of different compositions on temperature and magnetic field (AE-effect) has been made using a ultrasonic method. The variation of Young's modulus with temperature follows Wachtman's equation. The dependence of the Young's modulus on magnetic field is explained using a theoretical model suggesteds by Lewis and...
