in this work, we report synthesis and characterization of bi2o3 nanoparticles loaded on mesoporous mcm-41 nanoparticles by a simple solid-state dispersion (ssd) method. monoclinic bismuth oxide nanoparticles were prepared by polyacrylamide gel method and used as loading materials on the prepared mesoporous mcm-41 as a supporting material. fourier transform infrared spectroscopy (ft-ir), x-ray p...

cobalt (ii) chloride was used as a precursor to prepare co 3 o 4 nanotubes in reverse micelles. tween 80 was added as surfactant. the products were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy. the diameter of co 3 o 4 nanotubes was about 58 nm and the average length of them was around 261 nm. the study provides a simple and e...

cobalt oxide (co3o4) nanoparticleshave been synthesized by hydrothermal method using mixture of cobalt(ii)chloride, triton x-100 and koh in an autoclave at 180 °c for 6 h followed by heating at 400 ºc for 3 h in air. the product have been characterized by fourier transform infrared (ft-ir), uv-vis spectroscopy, powder x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission ...

cupric oxide nanostructures were synthesized via a simple reaction between copper nitrate and sodium hydroxide using a sonochemical-assisted method. the synthesized cuo was then characterized using x-ray diffraction, scanning electron microscopy, transmission electron microscopy, fourier transform infrared, ultraviolet-visible and photoluminescence spectroscopy. our studies show that the cuo na...

The Ultra-nanocrystalline diamond (UNCD) was synthesized by the detonation of a high explosive mixture in water confinement. The presence of a diamond phase was revealed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). X-ray line broadening (XRLB) was used to evaluate the peak profiles of diamond nanoparticles and their corresponding average crystallite sizes. The micro st...
