TL;DR: In this paper, a new theory was proposed for the potentiostatic current maximum which leads to more reliable values of the nuclear number density and to a better distinction between instantaneous and progressive nucleation.

TL;DR: In this paper, a study of the electrochemical nucleation of silver on vitreous carbon from aqueous solutions of silver nitrate is presented, where the nucleation is shown to be progressive and mass transferred controlled.

TL;DR: In this article, a truer representation of the relationship between current and nuclear density was obtained using the implicit method of numerical simulation, where the current transients resulting from three-dimensional electrochemical nucleation of metals can be related to the number density of surface nuclei.

TL;DR: In this article, the electrodeposition of copper onto vitreous carbon from aqueous solutions using the potentiostatic and linear sweep methods was studied using the linear sweep method, and the composition of the solution was systematically varied in order to investigate the effect of concentration of copper ions, concentration of chloride ions, pH and supporting electrolyte on the kinetics of nucleation and growth.

TL;DR: In this article, the electrochemical nucleation of mercury on vitreous carbon from solutions of mercurous nitrate in aqueous KNO3 has been investigated as a function of overpotential and mercurous ion concentration.
