Electrochemical-induced particle formation
One of our research work is dealing with the synthesis of particles by electrochemical method. One of them is synthesis of magnetite (Fe3O4) nanoparticles. How can electrochemical process induce particle formation? This article will give some discussion about electrochemical-induced particle formation with an example about the formation of magnetite nanoparticles. One important thing that must…

Particle technology
We are working on the synthesis of materials in the form of particles by electrochemical and sol-gel method. Why such form of materials is important. Here we will discuss briefly about it. Perhaps we don’t realize that everyday we deal with products in the form of particles or powders. Most women and girls are familiar…

Silica gel from bagasse ash
We have succesfully produced silica gel from bagasse ash (boiler waste of cane sugar mills) by a simple low-energy chemical method. We published the results on Advanced Powder Technology, a reputable scientific journal published by Elsevier BV on behalf of The Society of Powder Technology Japan. The method can be an alternative for the commercial…

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 Advanced Powder Technology (2011), in press Synthesis of magnetite nanoparticles by surfactant-free electrochemical method in an…
