Abstract: The hydrogen polymer electrolyte membrane (PEM) fuel cell provides enormous potential for a future with clean energy. However, PEM fuel cells and electrolyzers have not yet reached widespread commercial adoption, and key barriers are related to inefficient heat and mass transport in microscale porous materials. Mass transport limitations arising from liquid water flooding in low temperature PEM fuel cells and oxygen gas bubble accumulation in PEM electrolyzers leads to significant inefficiencies. If these issues become resolved, smaller and more reliable devices could be produced at a lower cost. Mass transport limitations can be minimized through the development of optimized materials, which have tailored pore structures, connectivities, conductivities, and surface wettabilities. The porous materials could be customized for mass transport with detailed information about their structure and the dominating mass transport mechanisms that result from these structures. I will discuss X-ray based visualization techniques, such as microcomputed tomography, synchrotron X-ray radiography, and neutron radiography, for investigating multiphase transport in PEM fuel cells and electrolyzers. Biography: Prof. Aimy Bazylak is the Canada Research Chair in Thermofluidics for Clean Energy; Director of the University of Toronto Institute for Sustainable Energy; and an Associate Professor in Mechanical & Industrial Engineering. Her research is focused on studying microscale and nanoscale materials for tailored heat and mass transport for clean electrochemical energy conversion technologies. In 2014 she became a Fellow of the Canadian Society for Mechanical Engineering, and she was recognized as an Alexander von Humboldt Fellow in Germany in 2015.

Friday, February 2nd at 12:15 p.m., Dr. Ebrahim Ghafar-Zadeh (PhD, P.Eng), Director of Biologically Inspired Sensors and Actuators Laboratory, will be presenting “High Throughput CMOS Sensors and Actuators: An Emerging Technology for Automation of Biological Laboratories”. Day & Time: Friday, February 2, 2018 12:15 p.m. ‐ 1:15 p.m. Speaker: Dr. Ebrahim Ghafar-Zadeh Biologically Inspired Sebsors and Actuators ( BioSA) Dept. of Electrical Engineering and Computer Science Lassonde School of Engineering York University Location: Room: ENG 288, George Vari Centre for Computing and Engineering 245 Church Street Toronto, Ontario M5B 2K3 Contact: Maryam Davoudpour Organizer: WIE IEEE Toronto, IEEE Ryerson Student Chapter, Instrumentation-Measurement/Robotics-Automation, Magnetics, and Computer Science Department of Ryerson University Abstract: Recent advances of Complementary Metal Oxide Semiconductor (CMOS) Lab-on-Chip (LoC) technologies have greatly attracted the attentions for a variety of life science applications including DNA sequencing, drug discovery and automation of biological laboratories. A CMOS based LoC consists of a microfluidic device for directing the biological/chemical samples towards sensors (e.g. magnetic, optical or capacitive sensors) or actuators (e.g. magnetic or electrical actuators). An array of sensors or actuators can be realized on the top of CMOS integrated circuits (IC) for accurately measurement of chemical and/or biological signals. High throughput microfluidic/CMOS technology for cellular and molecular analysis is in a very early stage of development and there are several critical challenges that must be investigated and resolved. In this talk, professor Ghafar-Zadeh will discuss new perspectives and challenges for the design and implementation of hybrid microfluidic CMOS sensors and actuators. Also he will demonstrate and discuss his recent research achievements in this emerging field of research. Biography: Ebrahim Ghafar-Zadeh (PhD, P.Eng) received his BSc ( KNT University, Tehran Iran), MSc (University of Tehran, Iran) and PhD ( Ecole Polytechnique de Montreal, Canada) degrees in Electrical Engineering in 1992, 1994 and 2008 respectively. In recognition of his innovative research in the topic of hybrid microfluidic/microelectronic systems, Dr. Ghafar-Zadeh received several postdoctoral fellowship awards including NSERC PDF and FRQNT PDF and he perused two postdoctoral fellows in the Dept. of Electrical and Computer Engineering, McGill University; and the Dept. of Bio-engineering, University of California, Berkeley. Dr. Ghafar-Zadeh has published more than 100 journal and conference papers and a book titled CMOS Capacitive Sensors for Lab-on-Chip applications. Since 2013, he has been an assistant Professor, in the Dept. of Electrical Engineering and Computer Science, York University, Toronto, Canada. Dr. Ghafar-Zadeh is the director of Biologically Inspired Sensors and Actuators Laboratory. |
