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.

 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.

ExpecTAtions is a two-day workshop that prepares Waterloo Engineering students to undertake a teaching assistantship. To serve as a TA, you are required to complete the ExpecTAtions workshop. After full attendance and successful completion of all required activities you will receive a certificate noting your achievement.

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.

ABSTRACT:  Nano-structured and hierarchically structured materials play a vital role in electrochemical power source technologies: batteries, super capacitors and fuel cells.  They are becoming increasingly important in electrochemical synthesis technologies such as electrolysis, photolysis, CO2 electro-reduction and production of value added chemicals.

ABSTRACT:  Radiocesium (Cs) removal from tap waters was an emerging issue after the Fukushima Daiichi Nuclear Power Plant Disaster, during which a total of approximately 3.3×10¹⁶ Bq Cs was released to the environment. Radioactive fallout can lead to contaminated surface water and/or groundwater, eventually will enter drinking water production chain. Radioactivity in drinking water, even at low levels, can be harmful since the radiocesium can be bioaccumulated in body.

ABSTRACT:  The phenomenon of adsorption of colloidal particles at interfaces to stabilize the emulsions has been known for more than a century. Today, particle-stabilized emulsions, or so-called Pickering emulsions are receiving growing attention in the scientific and industrial communities. However, our fundamental understanding of the connection between particle properties and emulsion characteristics is still surprisingly poor.
