Co-Principal Investigator, Funding SERC-DST (Apr 2007 - Mar 2013) (IR/S3/EU-04/2006). This work was in collaboration with Prof. Sanjeev Kumar and Prof. V. Kumaran
The main objective was to synthesize monodisperse nanoparticles (COV <5%) in continuous flow microfluidic reactors. Specifically, we are involved in designing and fabricating microfluidic reactors and understanding the rapid kinetics of nanoparticle formation reactions. These aspects will complement the expertise of Prof. Sanjeev kumar's group in modelling using tools such as CFD/Population balances , and expertise ofProf. Kumaran's group in electrically actuated flows in flexible tubes. Another objective is to develop robust techniques for forming ordered arrays of gold nanoparticles and their application as Surface-Enhanced Raman Spectrosscopy (SERS) devices, chemoresistive sensors, Flash memory devices, Nanoporous Fuel cell catalyst layer, and Dye sensitised solar cells.
