Electrosynthesis of magnetite nanoparticles

We have successfully synthesized magnetite (Fe3O4) nanoparticles and SiO2-coated magnetite nanoparticles by an enviromentally friendly electrochemical method. The results have been published in: (i) Advanced Powder Technology and (ii) Journal of Nanoparticle Research. Below is summary of the articles
