Metal oxide nanoparticles are of practical interest in a variety of applications including high-density information storage [1], magnetic resonance imaging [2] and targeted drug delivery [3]. Many of these applications require particles of predetermined size and narrow size distribution. Processes that lead to particles with these characteristics are therefore of considerable interest. Cobalt f...

Wet chemical method was applied for the synthesis of cobalt-ferrite nanoparticles. The physicochemical properties were investigated by number analytical techniques. TGA revealed thermal stability synthesized X-ray diffraction studies displayed nanoparticles crystalline nature. Structure confirmed via infrared spectroscopy manifesting Co and Fe ions absorption peaks. Morphological showed employi...

Nanometric Carbid Silicon (SiC) supported monometallic and bimetallic catalysts containing Fe, Co, Ni transition metals were prepared by wet impregnation method. Multiwall carbon nanotubes (MWCNTs) were synthesized over the prepared catalysts from catalytic decomposition of acetylene at 850°C by thermal chemical vapor deposition (TCVD) technique. The synthesized nanomaterials (catalysts and CNT...

Cobalt ferrite is an important magnetic material due to their large magneto-crystalline anisotropy, high cohercivity, moderate saturation magnetization and chemical stability.In this study, cobalt ferrites Nanoparticles have been synthesized by the co-precipitation method and a new microemulsion route. We examined the cation occupancy in the spinel structure based on the “Rietveld with energies...
