The objective of this short course is to provide a working knowledge of electrochemical impedance spectroscopy. This will include a discussion of the theory of EIS, its application, and most importantly, hands-on laboratory experience. All attendees will use EIS to measure corrosion rates, characterize a metal oxide, examine the effectiveness of a corrosion inhibitor, and determine battery performance. In addition, the attendee will learn methods of data presentation, data interpretation and analysis, and model fitting both in the classroom and in the laboratory. The attendee will become familiar with commercial hardware and software for experimental control, data analysis, and model fitting. Since it is intended for all participants to use the equipment in the laboratory sessions, the class size is limited to 32 students.
