Thursday, December 11, 2014 3:30 pm - 3:30 pm EST (GMT -05:00)

Seminar - “Towards The Unraveling of Structure and Properties of Nanothin Ionomers in Polymer Electrolyte Fuel Cells” by Kunal Karan, Associate Professor, Department of Chemical and Petroleum Engineering, University of Calgary

ABSTRACT:  Mid-December 2014 is set to be the historical launch of the first commercial fuel-cell vehicle, heralding a transition from fossil-fueled vehicles to cleaner hydrogen-fed vehicles. Despite this significant milestone in making, there is an aggressive approach for further reduction in the cost of the polymer electrolyte fuel cell (PEFC) stacks while maintaining/ improving its electrochemical performance.

Seminar - “Stimuli-Responsive Degradation Strategy for Accelerated Drug Release” by Jung Kwon (John) Oh, Department of Chemistry and Biochemistry, Concordia University

ABSTRACT:  Stimuli-responsive degradation (SRD) or cleavage of dynamic covalent bonds in response to external stimuli is a promising property in the development of polymer-based multifunctional nanomaterials. These nanomaterials are designed to degrade upon the cleavage of dynamic linkages in response to single or multi-stimuli, thus tuning lower critical solution temperature, controlling nanoparticle morphologies, fabricating highly-ordered nanopores, and enhancing controlled drug release.

Seminar - "The Future of Polygeneration: Environmental and Economic Progress" by Dr. Thomas A. Adams ll, Assistant Professor, Chemical Engineering, McMaster Univeristy, Hamilton, ON

ABSTRACT:  In order to solve the energy crisis, we need high-impact technology solutions which allow us to make and use energy products in a way that provides a similar standard of living but with a much-reduced environmental footprint. It's not easy.  Any new approaches will have to not only be proven to be less damaging to the environment, but they must be politically and socially acceptable, and they must still be profitable enough such that the industry actually wants to try them.

Seminar - “Enabling RNA as a Biomedical Therapeutic Through Customized Nanotechnology Platforms" by Dr. Omar Khan, Postdoctoral Associate, Massachusetts Institute of Technology, Boston, MA

ABSTRACT:  The exogenous delivery of RNA into tissues has shown great potential for the treatment of destructive diseases by therapeutically controlling the expression of genes within those tissues.  A key need for the broad application of RNA for therapeutic biomedical engineering applications is the development of safe and effective delivery systems capable of targeting specific cells within the body.

Seminar -“Hybrid Polymer Blend Nanocomposites for Electrical and EMI Shielding Applications” by Uttandaraman Sundararaj, Professor, Dept. of Chemical and Petroleum Engineering, University of Calgary

ABSTRACT:  Polymer nanocomposites have unique multifunctional properties resulting from the size and shape of the fillers and display superior electrical, thermal and mechanical properties to conventional polymer composites due to the nanoscale size of the filler.  Multiwall carbon nanotubes (MWCNT) as well as Copper and Silver nanowires were melt-mixed with polymers via solution mixing and in miniature mixers, and electrical and mechanical properties were tested.

Seminar - “Biomaterials Topography for Stem Cell Regulation and Tissue Engineering Applications”, Evelyn KF Yim, Department of Biomedical Engineering, Mechanobiology Institute Singapore, Department of Surgery, National University of Singapore

ABSTRACT:  Stem cells respond to both physical and biochemical changes in their stem cell niche. An ideal scaffold for tissue engineering application should mimic the microenvironment for natural tissue development and present the appropriate biochemical and topographical cues in a spatially controlled manner. Studies have shown that physical forces from the substrate topography play a role in stem cell proliferation, migration and cell fate determination.
