“…Indeed, these techniques allow the in situ determination of many kinetic and thermodynamic parameters that are impossible to acquire otherwise. For example, it is possible to monitor the evolution of the open circuit potential vs time of a metallic material [1,2], to evaluate its passivation ability, or to acquire significant information about the nature of the electro-active systems [1,[3][4][5][6][7] that are present in the electrolytic melt, this list being by far non-exhaustive.…”
