The studies at UMR8235 are performed in the context of physico-chemistry and interfacial reactivity. Various domains are concerned: corrosion and its inhibition, surface treatments, storage and conversion of energy, and, more recently, applications in biology, cultural patrimony protection, and, more generally, natural environments to understand the behaviour of electrochemical interfaces. This explains why the laboratory is positioned at the junction of fundamental research, its primary assignment, and activities with partners of various economic sectors using electrochemical concepts, techniques, and processes.
