The Physics & Astronomy Colloquium Series presents Gerardine G. Botte of Ohio University on “Graphene from Coal Char: Synthesis and Applications” on Friday, Sept. 12, at 4:10 p.m. in Walter 245.

Abstract: Graphene continues to emerge as the most promising nanomaterial due to its unique combination of superb properties, which opens the way for its exploitation in a wide spectrum of applications ranging from nanoelectronics, composite materials, sensors to electrochemical electrodes in lithium ion batteries, solar cells, transparent electrodes, energy cells, barriers, heat radiation, conductive inks, capacitors, ultracapacitors, etc. Despite its superb properties, the use of graphene is limited by cost. Currently, graphene is being produced from graphite. Graphite utilizes an expensive process that has contributed to the limited use of graphene. Additionally, there are limited sources for graphite in the United States; with 70 to 80 percent coming from China. To confront these issues, Botte and members of her research group are working on the development of a new process, the “Coal to Graphene” process. In this talk, a summary of the development of the technology and the process will be presented along with the characterization of the material and its performance in different electrochemical devices.
