Electronic, structural, and magnetic properties of cobalt aggregates embedded in polypyrrole

Article Abstract:

The synthesis and characterization of cobalt aggregates electrochemically incorporated on composite polypyrrole fills are reported. The synthesis revealed that the magnetic response obtained by in situ alternating gradient field magnetometry (AGFM) allows prediction of the possibility of obtaining a magnetic polymer with superparamagnetic particles with sizes below 10nm.

Formation of cobalt nitrate hydrate, cobalt oxide, and cobalt nanoparticles using laser vaporization controlled condensation

Article Abstract:

The laser vaporization controlled condensation (LVCC) method for the synthesis of cobalt nitrate hydrate, cobalt oxide, and cobalt nanoparticles, produced using high purity cobalt metal target at various N2 and O2 pressures, is discussed. Several experiments show that the LVCC method is used to make nanoparticles of various semiconductors and metal oxides.

Optical CO gas sensor using a cobalt oxide thin film prepared by pulsed laser deposition under various argon pressures

Article Abstract:

The cobalt oxide thin films prepared by pulsed laser deposition are used to investigate an optical CO gas sensor. It is suggested that based on the relationship between the morphology and the optical sensor properties of the films, the Ar pressure is suitable with high sensitivity and good mechanical stability.
