Title
From Macromolecular Structure to Polymer Processing: Bridging length and time scales
Abstract: As demands on cleaner environment and sustainability increase the Indian plastics industry will have to focus on the production andprocessing of environmentally benign polymers. Development of such plastics requires a deeper understanding of the intricate relations between the structure and topology of macromolecules and their processing behavior and properties. A significant scientific challenge here is to be able to connect physical phenomena that occur over several orders of magnitudes of length and time scales. To meet this challenge it is necessary to equip oneself with a tool-box of scientific techniques that include experimental measurements of the structure and properties of polymers from molecular to macroscopic length scales coarse-grained-mean-field theory meso-scale simulations continuum CFD simulations and experimental validation. In this presentation Dr. Ashish Lele will summarize the key historical developments in this area present two recent contributions from NCL touch upon some industrially relevant problems to which we are applying our tools and give my perspective on the current state of research.About the Speaker: Dr. Ashish Lele is a Scientist at the National Chemical Laboratory (NCL) Pune India. He received his Bachelor's degree in Chemical Engineering from the Institute of Chemical Technology in Mumbai (1988) and a Ph.D. in chemical engineering from the University of Delaware (1993). Dr. Lele has made many novel and high impact contributions to polymer science and engineering. The thrust of Prof. Lele's research has been the deep probing of polymeric material microstructures at the molecular and mesoscopic length scales and then relating these to their macroscopic dynamical and equilibrium properties. His significant contributions include molecular tailoring of stimuli responsive smart hydrogels new insights into the anomalous rheological behavior of complex fluids and the coupling of macromolecular dynamics and polymer processing. Dr. Lele has been awarded the CSIR Young Scientist award (1996) the Indian National Science Academy Young Scientist award (1998) and the Shanti Swarup Bhatnagar Prize in Engineering Science (2006). Recently Dr. Lele has been awarded prestigious Infosys Prize for Engineering and Computer Science for year 2013 for his incisive contributions in the area of Rheologically complex fluids and polymer processing. He is a Fellow of the Indian National Academy of Engineering and of the Indian Academy of Science.
