Lecture by Yuanyue Liu – American Corners

Via Zoom

On 23rd September 2021, Yuanyue Liu will give the lecture entitled “First-Principles Simulations of Electron Transport and Electrocatalysis of 2D Materials”, under the American Corner @Técnico.

  • 23rd September, 16:00 – online (via Zoom).
  • Speaker: Yuanyue Liu (Walker Department of Mechanical Engineering, Cockrell School of Engineering, UTAustin, Texas, USA).
    • Yuanyue Liu is currently an assistant professor at Department of Mechanical Engineering and Texas Materials Institute at University of Texas at Austin. He received B.S. degree from University of Science and Technology of China (USTC) in 2008, and Ph.D. from Rice University in 2014. He did postdoc studies at National Renewable Energy Laboratory (NREL) and California Institute of Technology, and then joined UT in Fall 2017. His research focuses on developing and applying atomistic simulation methods to study electronic and energy materials. He has been cited > 12,000 times.
  • Title: “First-Principles Simulations of Electron Transport and Electrocatalysis of 2D Materials”.
    • Abstract
      Computational methods based on quantum mechanics (first principles) are powerful tools to extract atomic-level understanding of materials and processes, which may be difficult to access experimentally. Here I will show two examples, where we develop and apply first-principles methods to understand (1) why 2D semiconductors generally have low electron mobility [1,2,3], and (2) the active site structure and kinetic mechanism of single metal atom embedded in graphene for electrochemical CO2 reduction and oxygen reduction [4,5,6].
