  Title：Tribological studies with atomic force microscopy Speaker：Qun-yang Li Time： 3:00pm.   Date： June 7，2012.   Venue：Conference Room 434, Mechanics Building Host：Prof. Fa-xin Li   Abstract：     Materials interact with their surroundings primarily through their surfaces. Surfaces and interfaces are the places where a substantial degree of energy dissipation, structural instabilities, and other interesting mechanical phenomena take place. In this talk, I will discuss two new and fundamental observations from atomic force microscopy (AFM) to illustrate how frictional properties of both novel (atomically-thin two-dimensional films[1]) and traditional materials (rock materials[2]) are dictated by nanoscale mechanisms.

About the speaker：
    Dr. Qunyang Li received his B.E. (2001) from Tsinghua University and got Ph.D (2008) from Brown University. He did postdoctoral research in Brown University and University of Pennsylvania in the year 2001 and 2003. Now he works in Tsinghua and does research on the field of mechanics about Micro/Nano sized solids.
