In situ transmission electron microscopy for energy storage and optoelectronic applications

In situ transmission electron microscopy (TEM) is one of the most powerful approaches for revealing physical and chemical process dynamics at high resolutions. This seminar summarises the most recent developments in TEM techniques; in particular, how they are able to visualise various events, measure properties and solve problems in the field of energy, by revealing detailed mechanisms at the nanoscale. The related applications include use of rechargeable batteries such as lithium-ion, sodium-ion and potassium-ion, to store the energy generated by photovoltaics. To promote various applications, the methods of introducing in situ stimuli of heating, cooling, electrical biasing, light illumination and liquid and gas environments will be presented, with a focus on electrical biasing and probing. This seminar may inspire future research on new energy materials in diverse energy-related areas.
