The ECS Calgary Student Chapter organized an afternoon workshop on advanced electrochemical impedance spectroscopy (EIS) at the end of October 2017. The instructor for this workshop was Dr. Mark Orazem, a distinguished professor of chemical engineering at the University of Florida, an adjunct professor at the Beijing University of Chemical Technology, and a highly respected expert in EIS. This workshop reviewed the basics of impedance measurements and then focused on how to develop models for interpreting impedance data. The workshop was very successful, with over 90 attendees from the Department of Chemistry and a number of departments within the Schulich School of Engineering at the University of Calgary, as well as a few students from the University of Alberta in Edmonton. This event also served to attract 14 new members to the Calgary Student Chapter.

Workshop Content:

  •     The motivation for using impedance spectroscopy advantages as compared to other transient techniques and the conditions under which its use is ideally suited; analogues and more
  •     The basic concepts of how impedance is measured;
  •     Proper selection of experimental parameters;
  •     Graphical representation of impedance data, including methods to extract some physically meaningful parameters;
  •     Constant-phase elements;
  •     Application of electrical circuit
