Abstract: Graphene is recognized as one of the nanomaterials that could revolutionize numerous industries over a wide range of sectors due to its distinctive properties, including large specific surface area, high electrical and thermal conductivity, good chemical stability, ultrahigh mobility, as well as great mechanical strength and Young’s modulus. The European Commission (EU) has recently committed 1 billion euros over 10 years to fund graphene R&D through an EU Future Emerging Technology flagship grant. The recent developments in Yu’s lab on production and manipulation of graphene will be introduced, in which mainly toward clean energy applications, such as supercapaciors, batteries and hydrogen production.
    Supercapacitors are high power density electrochemical energy storage technologies with excellent cyclability, however in order to render them suitable for a variety of applications including automotive, electronics, grid scale energy storage, etc., advanced electrode materials are required that can improve the energy density and reduce overall costs. 
    A few generations of graphene developed in Yu’s group and used as high performance supercapacitor electodes which significanlty improved the capacitance and energy density of these devies. Yu’s group has also developed the 1st graphene based, transparent and flexible supercapacitor for wearble/flexible electronics in the world.  Recently, advanced supercapacitor based on three-dimensional graphene sponge based, consists of an interconnected network of graphene, have been designed and dmonstrated 4 time higher of energy density than the commercial activated carbon supercapacitors. Other energy related work  in Yu’s group including photocatalyst for H2 production and battert sensor.
 
 
Biosketch: Aiping  Yu is an assistant professor in the Department of Chemical Engineering at University of Waterloo. Her current research interests are in the development of graphene related nanomaterials for supercapacitor, H2 production, and fuel cell bipolar plates. She received her Ph.D. in Chemical and Environmental Engineering from the University of California-Riverside under the supervision of Prof. Robert Haddon. Prior to joining Waterloo, she was working in GE, plastic, Philadelphia, USA.  She has published 1 book and 1 book chapter, 37 papers in peer reviewed journals, including Science, JACS, NanoLetters. These publications have earned her to date more than 3000 citations. She is listed as inventor in 4 US patents and provisional patents, with one licensed to Tessera, Inc., San Jose, California.
