Seminar - “Production of Polyglutamic Acid Nanoparticles for Controlled Release of Anti-Cancer Drugs” by Dr. Argyrios Margaritis, Professor of Biochemical Engineering, Dept. of Chemical and Biochemical Engineering, University of Western Ontario, London,ON

ABSTRACT:  In this work we present results on the use of Gamma-Polyglutamic Acid (PGA) biopolymer to produce nanoparticles and encapsulate the anti-cancer drug Doxorubicin (DOX). Microbially produced PGA is used alone and in combination with Chitosan (CS) to form DOX-loaded nanoparticles at different conditions. The main mechanism of nanoparticle formation is the ionic complexation between PGA, DOX and CS.

Park and Veva Reilly Distinguished Seminar - "Silicon Based Nano-Architectures for Advanced Lithium-Ion Batteries" by Fathy M. Hassan, Department of Chemical Engineering, University of Waterloo

 ABSTRACT:  Silicon has the potential to revolutionize the energy storage capacities of lithium ion batteries, propelling their capabilities to meet the ever increasing power demands of next generation technologies. Silicon has a huge energy storage capacity (4200 mAh/g), ten times higher than the conventionally used graphite materials (372 mAh/g). To avoid the operational stability problems associated with the use of silicon-based anodes, the electrode structure needs to be architectured on the nanoscale.

Seminar - “Development of Hetero-Nanostructures with Multifunctional Properties”, Jin Zhang, PhD., Associate Professor, Department of Chemical & Biochemical Engineering, University of Western Ontario, London, Ontario

ABSTRACT:  Tailor-made nanosystem refers the integration of different components/materials at nanoscale which can show multi-functional and unique properties. Rational design and fabrication of such hetero-nanostructures are vital to break the boundaries of traditional technologies. One of Dr. Jin Zhang’s research interests lies in producing magnetic and optical hetero-nanostructures which show distinguish properties, and have been applied in various devices, e.g. data storage, sensors, etc.
