Abstract

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.
