Abstract
  Different iron oxide nanoparticles (Fe3O4 and Fe2O3) were prepared by the sol-gel method (titration). The prepared nanoparticles were heated at 90 and 400°C. The morphology surface and structures were characterized by Fourier Transform Infra-Red (FT-IR) and Ultraviolet/Visible (Uv/Visible) measurements, ...  Read More ...

Abstract
  Vanadium pentoxide and Tin dioxide nanoparticles were prepared by hydrothermal methods to remove methylene blue (MB) and bromothymol blue (BTB) dyes). First the prepared nanoparticles were heated at different temperature (90 oC and 500 oC). Then these nanoparticles were characterized by different methods ...  Read More ...
