I am responsible for daily TEM lab management and teaching TEM graduate level course. We welcome all kinds of collaboration from academic and industry to solve materials problems at the atomic level using analytical transmission electron microscopy.
My research interests emphasize application of analytical transmission electron microscopy to study the structure and chemistry of the nanophase and bulk materials with emphasis on catalytic, semiconductor, metallic and ceramic materials. We focus on understanding the relationship between the size, shape, distribution and structures to the properties of the nanostructures including clusters, wires, tubes and thin films. One aspect of the research is to synthesize and characterize uniform-size-distributed nanoparticles with unique properties. Another aspect of the research is to focus on understanding the surface and interface role in heterogeneous catalysts, thin film, and phase transformation of nano and bulk material systems.
Analytical Electron Microscopy: This course covers basic principles and practical labs of transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), and spectroscopy techniques of X-ray energy-dispersive spectroscopy, electron energy-loss spectroscopy (EELS), and energy-filtering TEM imaging. The combination of these TEM techniques is widely applied to all kinds of materials research in nanoscience and nanotechnology.
