This course covers the basic theory and application of electrochemical science. It is targeted toward people with a physical sciences or engineering background who have not been trained as electrochemists, but who want to add electrochemical methods to their repertoire of research approaches. There are many fields in which researchers originally approach their work from another discipline but then discover that it would be advantageous to understand and use some electrochemical methods to complement the work that they are doing.
The course has just been fully revised to include more practical examples and a more manageable volume of material. It complements a revised sister course, Fundamentals of Electrochemistry: Basic Theory and Thermodynamic Methods, offered by the same instructor at the ECS spring meetings. The two courses have a different emphasis, and each is designed to be a stand-alone introduction to electrochemical fundamentals. If both courses are desired, they can be taken in either order.
