The Electrified Solid-Electrolyte Interface

In the following, we will concentrate on water as the electrolyte, but most of what we will be discussing can be generalized to other electrolytes. We will also focus on processes involving proton transfer. The reason is that most of the processes of interest in energy transformations are associated with proton transfers to or from the surface. Again, the majority of what will be discussed is easily transferable to other types of processes.
