Dr. GianLuigi Botton of McMaster University will present a seminar.
Title:
High-Resolution Electron Microscopy and Spectroscopy:
Applications to Energy-related Materials and Devices
Abstract:
Transmission electron microscopy is an invaluable technique to study the detailed structure of materials at unprecedented spatial resolution. Beyond imaging, this technique, when combined with analytical methods such as energy dispersive and electron energy loss spectroscopies, provides information on the chemical composition, chemical state and localized strain in a broad range of materials. The versatility of an electron microscope makes it possible to provide useful information related to both industrially relevant materials and the most fundamental questions in quantum materials.
In this presentation, I describe recent developments in electron microscopy showing applications related to catalysis materials used in fuel cells and energy storage materials used in batteries in order understand their structure and evolution following operation. I will show some examples of detailed studies of the plasmonic response metallic nanostructures demonstrating that it is possible to probe details of surface plasmon resonances with much higher spatial resolution than ever possible. Examples will also include liquid-cell microscopy work to highlight the potential of in-situ methods to study the electrodeposition and growth of materials inside the electron microscope.
