ECS Short Courses

Toronto, ON, Canada | Sunday, May 12, 2013

Short Course #1
Basic Impedance Spectroscopy
Mark E. Orazem, Instructor

Please visit the Toronto meeting page for registration information. Early-Bird Registration rates are in effect until April 12, 2013. See a list of all Short courses offered at the Toronto meeting.

This course is intended for chemists, physicists, materials scientists, and engineers with an interest in applying electrochemical impedance techniques to study a broad variety of electrochemical processes. The attendee will develop a basic understanding of the technique, the sources of errors in impedance measurements, the manner in which experiments can be optimized to reduce these errors, and the use of graphical methods to interpret measurements in terms of meaningful physical properties. The topics to be covered include:

  1. The motivation for using impedance spectroscopy advantages as compared to other transient techniques and the conditions under which its use is ideally suited,
  2. The basic concepts of how impedance is measured,
  3. Proper selection of experimental parameters,
  4. Graphical representation of impedance data, including methods to extract some physically meaningful parameters,
  5. Constant-phase elements,
  6. Application of electrical circuit analogues, and
  7. The meaning of the Kramers-Kronig relations.

The concepts will be illustrated by applications to different systems including corrosion, fuel cells, batteries, and transport through membranes such as skin. A list of suggested references will be provided.

This course is the first in a two course sequence offered at alternating ECS meetings by Professor Orazem. The second course in the series, “Advanced Impedance Spectroscopy,” introduces model development based on proposed reaction mechanisms, statistical analysis of impedance data, and regression analysis.

 

About the Instructor

Mark E. Orazem is a recognized expert on impedance spectroscopy. He has offered both introductory and advanced short courses on the topic at annual meetings of the Electrochemical Society and at the Fuel Cell Seminar. He also has delivered this course to different companies and to local sections of the ECS.

Orazem obtained his BS and MS degrees from Kansas State University and his doctorate in 1983 from the University of California, Berkeley. In 1988 he joined the faculty of the University of Florida where, since 1992, he holds the position of Professor of Chemical Engineering. Prof. Orazem is the recipient of two teaching awards and three research professorships from the University of Florida. He was recognized as an outstanding educator in 2004 by BP Azerbaijan. He was recognized as the 2005 College of Engineering Distinguished International Educator, and he was recognized as a 2008 Blue Key Distinguished Professor. Prof. Orazem is a Fellow of The Electrochemical Society and served for ten years as Associate Editor for the Journal of the Electrochemical Society. He is the President of the International Society of Electrochemistry. He has over 150 refereed publications and has co-authored, with Bernard Tribollet of the CNRS in Paris, a textbook on the subject, Electrochemical Impedance Spectroscopy. In 2012, Orazem received the ECS Henry B. Linford Award for Distinguished Teaching.
