"Improving Supercapacitor Performance by Functionalization and Interfacial Assembly of Graphene"
ABSTRACT: Typical catalyst layers (CL) employed in PEM fuel cells are composed of a carbon supported Pt catalyst bound together with an ionomer, most often Nafion. Both the carbon support and ionomer play a crucial role in optimizing the catalyst utilization by proving electronic and ionic conductive pathways, respectively, without hindering gas transport. Upon fuel cell operation, the catalyst layer can degrade by one of 3 primary pathways:
ABSTRACT: There is considerable interest in the use of micro-scale processing (MSP) techniques for process development and optimization. The advantages of developing miniaturized versions of upstream and downstream unit operations that are scalable to actual production conditions are considerable. First, it reduces the material costs associated with running a large number of lab-scale or full-scale trials. Second, it accommodates a parallel approach for experimental testing, instead of the more traditional sequential approach, and thus is ideally suited for high-throughp
Abstract: In this talk, a recent University of Waterloo PhD graduate will discuss the transition from graduate student to assistant professor. Topics will include the ingredients of a good PhD project, structuring your future research plans, setting reasonable expectations, the joys and burdens of teaching, the paradoxical nature of hiring the best lab rats (PhDs) to become rat trainers (Professors), and generally how to begin ‘thinking like a professor’. By way of illustration he will discuss his own experience in the context of his research on ‘engineered’ porous mater
ABSTRACT: Hydrogels have been widely applied in medicine for applications including controlled release drug delivery, tissue engineering, wound healing, and ocular devices. Hydrogels based on “smart” materials that reversibly swell and deswell according to their environment offer additional advantages in terms of providing switchable physical and biological properties under relevant in vivo conditions. However, conventional synthetic “smart” hydrogels suffer from significant limitations in medical applications in terms of their difficulty to non-invasively admin
Abstract: CO2 reforming of CH4 plays important roles in the development of clean coal technology, renewable energy production, and biomass utilization. However, a viable (active, stable, and economical) catalyst is a must to facilitate this reaction. Ni-based catalyst is one of the most promising catalyst candidates but a long-term problem for this kind of catalyst is its tendency to be deactivated by carbon formation.
Abstract: The Hydrogen and Hydrogen Isotopes Technology Branch (formerly known as Chemical Engineering Branch) holds expertise and facilities that are focused on the development of energy technologies that make a beneficial impact on Canada’s use of clean energy. This capability area helps to ensure a clean and healthy environment for Canadians through development and use of clean energy technologies, and with securing options for Canada’s future energy needs and sustainability through nuclear technology.
ABSTRACT: Securing renewable energy sources is one of the most urgent challenges of our century. Fossil fuels are a limited resource and their use often has serious environmental impacts. As a result, there has been a major drive recently to advance science and technology for harvesting green and renewable energies using, for instance, the chemical energies of hydrogen and oxygen, photons, or even biomass.
