Research Interests
My research interests focus on the study of the atomic structure and defect behavior of nanomaterials, through in-situ and high-resolution TEM techniques. In particular, I am interested in understanding the relationships between the atomic/nano structure and the properties of nanomaterials, and the fundamental underlying mechanisms of structural and property changes induced by crystalline defects. My experimental work employs various TEM techniques, such as in-situ TEM heating, in-situ TEM nanoindentation, in-situ TEM straining, high-resolution TEM and aberration-corrected STEM. Additional techniques include scanning electron microscopy, x-ray diffraction, atomic force microscopy and SQUID measurements.The focus of the research is in Nanoparticles for Fuel Cells, Nanowires for Batteries, Nanocrystalline Metals and Metallic Nanoparticles, Copper Nano Interconnects and Carbon Nanostructures.
