Interfaces are ubiquitous in science and daily life, ranging from batteries to antimicrobial coatings. This is an advanced module that introduces the student to modern electrochemical and spectroscopic techniques and their applications in interface characterisation. Emphasis is given to those techniques, which are currently most important to chemical research both in industry and academia. At the end of the module, students should be able to understand the basic physical principles of these techniques and be able to decide which combination of techniques is best employed to tackle a particular problem of interface characterisation.
