Electrochemistry Fundamentals

In this section a general introduction to electrochemical measurements is covered. The material provides a general overview of electrolysis along with descriptions of the various forms of mass transport that may control an electrochemical reaction. Later sections introduce the ideas behind voltammetry and illustrate by animation how the concentrationof reagents changes during electrolysis. In the final sections detailed studies on topics such as fuels cells are outlined.

Electrochemical Impedance Spectroscopy

In this section we introduce the essential information required to analyse the response of an electrical circuit to the imposition of a steady or sinusoidally varying voltage. In the early parts we review the basic electrical components (resistors, capacitors and inductors) and define what is meant by current, voltage, capacitance, inductance and resistance. In the later sections we illustrate a method for breaking down complex circuits and predicting the impedance response.
