Electrocrystallization : Modelling and Its Applications

• Mathematical modeling of the electrocrystallization processes and its applications has long been a subject dear to Martin Fleischmann. The study of nucleation is fundamental to the understanding of crystallization. In the context of electrocrystallization, the terms can be applied to phase formation at preferred sites on the electrode surface and phase formation at surfaces without such sites. Two models of nucleation are presented: a heterogeneous model (nucleation on an indent); and a spherical-cap model representing homogeneous nucleation. The transients are recorded by applying a two-step potential profile to the working electrode. This procedure ensures the reduction of the initial falling background/charging current, so that the magnitude of this initial current cannot mask the very early stages of electrocrystallization. Martin sought to establish an approach to nucleation based on quantum electrodynamics.
