Carbon nanoparticles (CNPs) were synthesized by a simple way of incomplete combustion of kerosene. Synthesized nanoparticles were characterized by Scanning electron microscope (SEM), Energy dispersive x-ray (EDX), Powder x-ray diffractometry (XRD) and Fourier transform infrared spectroscopy (FTIR). The SEM particle sizes of prepared CNPs were found to be non-uniform. The average size of particl...

Alumina nanostructures, nanowires, and semicolumn nanotubes with high aspect ratios were synthesized by the chemical etching of porous alumina membranes (PAMs) in phosphoric acid solution. The morphology and structure of alumina nanostructures were analyzed by scanning electron microscopy (SEM), energy dispersive spectrum (EDS), and X-ray diffraction (XRD), respectively. The results showed that...

The development of appropriate processes for the synthesis of nanoparticles is an important aspect of nanotechnology. In this study, fungus mediated synthesis of silver nanoparticles using Microporus Xanthopus has been done. The dried macro fungi were powdered and boiled for 20 minutes to get the extracts. The extracts were treated with silver nitrate and kept in the dark conditions for 48 hrs,...
