TL;DR: In this article, the validity of the hypothesis of ligand excess is discussed for the voltammetric reduction of a metal ion (M) in the presence of a ligand (L).

TL;DR: In this paper, a semi-empirical expression for the normal pulse polarographic wave of the reduction of a metal ion in a labile metal-polyelectrolyte system, in the presence of an excess of ligand, was proposed.
15 citations
TL;DR: In this article, the theoretical models proposed for the study of electrode processes under diffusion control on rough surfaces are tested using quasi-two-dimensional experimental electrodes obtained by zinc electrodeposition.

TL;DR: Fractal characterization of zinc electrodeposits obtained in a quasi-two-dimensional film cell under suitable applied potential and zinc sulphate concentrations is reported in this article, which shows that these deposits are formed according to a Laplacian growth mode, and moreover, their self-similar fractal nature allows the generalization of the Cottrell law for diffusion-limited electrochemical processes occurring on these surfaces.

TL;DR: In this article, the experimental conditions under which electrodeposits are formed are changed, and they may become shaped either in a anisotropic dendritic form or without any apparent regularity as typical fractal aggregates.
Abstract: Non-equilibrium growth processes are conspicuous in nature. Electrodeposition constitutes a particularly fascinating example belonging to such general class of phenomena1. By slightly changing the experimental conditions under which electrodeposits are formed, they may become shaped either in a anisotropic dendritic form or without any apparent regularity as typical fractal aggregates2–4. A full understanding of the actual mechanism involved in electrodeposition is still lacking, and it is well recognized that this goal can only be achieved by working complementary from the theory, simulation and experimental practice of electrodeposition.
