Workshop A: "Operando Characterization of Energy Systems"
Organizers: Steve Heald (XSD), Yugang Sun (CNM), and Jianguo Wen (MSD)

Location: Building 401, Room A1100

In the study of energy systems such as batteries, fuel cells, photovoltaics, and catalytic processes it is important to simulate their actual operating conditions as close as possible. This workshop brings together researchers engaged in such operando studies of energy related systems. It will include experts in x-ray methods, electron microscopy, spectroscopy, and electronic structural theory as applied to energy systems. An important outcome will be to encourage cross-disciplinary discussions of the interactions between these techniques, and to highlight some of the growing capabilities being developed at ANL and elsewhere.
