About Me

Dr. Jayanta Chakraborty graduated in Chemical Engineering from Jadavpur University, Kolkata on 2001. Then he joined BOC group as engineer trainee and worked for a brief period before joining Indian Institute of Science, Bangalore as a graduate student. As a masters student Dr. Chakraborty worked with Prof. Giridhar Madras and gained significant experience on experimental research and specifically on polymeric and particulate systems. After finishing ME from IISc, he joined Atul Ltd, Valsad, Gujrat for another very brief industry exposure and finally decided to choose academia as his career.

After leaving Atul, Dr. Chakraborty joined Heritage Institute of Technology, Kolkata, as a visiting lecturer for a few months and then joined back to IISc again for PhD under the supervision of  Prof. Sanjeev Kumar. He worked extensively on population balance modeling and Monte Carlo simulation for nanoparticulate systems and gained good expertise in these areas. After finishing PhD in less than four years, Dr. Chakraborty joined Purdue University as post-doc under supervision of  Prof. D. Ramkrishna: a legendary figure for engineering of particulate system. His previous expertise took a final shape during these two years as he learnt to use mathematics in its elegant form in engineering problems.

After two years post-doctoral experience, Dr. Chakraborty joined IIT Kharagpur as Assistant Professor on July 2010. At IIT Kharagpur he nicely combined his theoretical and experimental experience to look for solutions of several practical problems in the field of particulate systems. His group focus on application of colloid science to engineering for efficient production of micron and submicron particles. One of the recent focuses of his group is  production of copper nanoparticles of better quality as a powder using a continuous process. We are also looking at production of stable nanofluids for heat transfer purpose. Recent expansion of interest area is in the area of energy materials where particulate systems are involved. Two sub areas in this directions are transparent conducting oxides and anti-reflecting glasses. Both involves manufacturing of uniform oxide nanoparticles.


Research Interests

The broad area of research for JCLABS is particle technology. The size range of interest is from nano to micro and a variety of application areas including nanofluid, anti-reflective coating and viral growth are addressed. We understand how parrticles behaves and believe that similar principles can be applied to solve a range of problems. Our application area spens from large scale industrial application like cleaning of spent sulfuric acids to making branched zinc oxide nanostructures for solar cells. Although our current interest includes experimental demonstration of easier synthesis protocols for nano and microstructures, the background theory and models are always in work to supply the necessary theoretical and quantitative support to the experiments. Current broad research area are as follows:
