Abstract :

In this talk, I will review some of our recent research efforts in novel nanomaterial fabrication, advanced nanomaterial characterization, and related nanotechnology development for energy and environmental applications. In the first example, we show that under uni-axial tensile loading, single crystalline ultrathin gold nanowires might fracture in both ductile and brittle-like modes, displaying distinctively different fracture morphologies and ductility. In the second example, we highlight our recent development and application of a novel technique, which involves the usage of silicon based micro-mechanical device that operates in conjunction with a quantitative nanoindenter within an electron microscope, to perform single fiber pullout experiments to study the multi-wall carbon nanotube (MWNT)/polymer (epoxy) interface. Finally, some potentially technological important applications related to energy and environment as well as our latest efforts on synthesis and characterization of two-dimensional materials beyond graphene will be briefly discussed.

Biography :

Jun Lou obtained B.E. and M.S. degrees in Materials Science and Engineering from Tsinghua University and Ohio State University, respectively, and his Ph.D. degree from the Department of Mechanical and Aerospace Engineering and Princeton Materials Institute at Princeton University. After a brief postdoc at Brown University he joined the Department of Mechanical Engineering and Materials Science at Rice University, and currently is an associate professor in the same department. He is a recipient of the US Air Force Office of Scientific Research Young Investigator Award and the ORAU Ralph E. Powe Junior Faculty Enhancement Award. His research interests include nanomaterial synthesis, nanomechanical characterization and nanodevice fabrication for energy, environmental and biomedical applications.
