Supercapacitive Characteristics of Potentiodynamically-Deposited Nano-Structured Cobalt-Nickel Oxide

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...

Exchange Coupling at Cobalt/ Nickel Oxide Interfaces

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...

Synthesis and characterization of manganese oxide and cobalt oxide nano-structure

The preparation of nanostructure type manganese oxide and cobalt oxide materials with the smallest particle size is reported here. The nanorod manganese oxide and cobalt oxide nanotube were prepared via a sol-gel reaction in reverse micelles from KMnO4 and CoCl2 with respectively source at room-temperature. The structure and surface morphology of the obtained manganese oxide were studied by mea...
