Professional Activities & Interests / Biographical Information
A major part of my NSF CRG (Chemical Research Group) research program (Billinge, Hogan, Kanazidis, Mahanti, Pinnavaia, Thorpe) involves a fundamental understanding of the physics of self-assembly of amphiphiles and physical properties of confined particles inside meso- and nanoporous media. The types of porous media we are concerned with have pore sizes ranging from several angstroms (as in Zeolites) to about 50 angstroms (as in MCM41 and novel systems discovered at MSU by Prof. Pinnavaia's group). We have developed a very efficient model to study via computer simulation the self-assembly problem and have been able to understand the physics of micellar formation and both co-operative and non co-operative routes to the formation of ordered structures. With Aniket Bhattacharya, who was a research associate here and is now an Assistant professor at the University of Central Florida, I am working on the temperature dependence of the critical micelle concentration using 3-dimensional lattice simulations. We have proposed a new way to look at this problem by monitoring the peak in the heat capacity as a function of temperature near the micellar transition. With Prof. Pinnavaia, we are exploring the possibility of using proto-zeolitic nano-clusters in enhancing the structural stability of nanoporous materials. Hoang Khang (grad student) and Hong Li (research associate) are involved in this project.
