An in-depth understanding of material behaviors under complex environment is critical for the development of advanced technologies and emerging nanoscale devices. These complex environments involves exposure of nanomaterials to various liquids, gases, extreme temperatures, pressures, electrical fields, and electrochemical reactions. Real-time transmission electron microscopy (TEM) is one of the emerging techniques poised to enable radical shift in our knowledge on how new materials behave in such environment. This presentation gives an overview of the PI’s efforts on understanding the atomistic mechanisms behind the catalyst degradation, capacity decay/thermal runaway in batteries, and phase transformations in liquid. In addition, topics related to the interaction of ionic transport and microstructural features (e.g. twin boundaries), atomic tunnels, and crystallographic misorientations will be covered. At the end, we will discuss new opportunities enabled by in-situ TEM to advance the current state of nanomaterials for applications in energy, electronics, and health.
Dr. Shahbazian-Yassar is currently a professor at the Department of Mechanical and Industrial Engineering at University of Illinois at Chicago. He has published more than 190 peer-reviewed journal articles in leading journals such as Science, Science Advances, Nature Energy, Nature Nanotechnology, Nature Communications, PNAS among others. He served as the President of the Midwest Microscopy Society and also the Materials Science Director at the Midwest Microscopy Society. He also served as the Chair and Vice Chair of Advanced Characterization, Testing, and Simulation Committee at the Materials, Metals, Minerals Society (TMS). He has hold various officer positions at the Microscopy Society of America and the Nanoengineering for Energy and Sustainability Committee at ASME society.
Light refreshments will be served.
