TL;DR: In this article, the current transient for three-dimensional nucleation on a finite number of active sites, followed by diffusion controlled growth, has been analyzed and the true nucleation rate per site can be obtained from the current maximum of single-step potentiostatic experiments.

TL;DR: In this article, the nucleation of lead onto vitreous carbon electrodes has been investigated and the number density of active sites for nucleation was found to vary with the overpotential but not with the concentration of lead ions in solution.

TL;DR: In situ infrared reflection spectra of thin polypyrrole films electrodeposited on platinum were obtained in aqueous KNO3, KCl and KF solutions, within a wide potential interval ranging from the reduced, insulating state, to the oxidative degradation of the material as mentioned in this paper.

TL;DR: In this paper, the nucleation of lead onto vitreous carbon electrodes has been investigated and the number density of active sites for nucleation was found to vary with the overpotential but not with the concentration of lead ions in solution.

TL;DR: Several available theoretical descriptions of the potentiostatic current transient that allow the determination of the rates of the nucleation process, A, and the number densities of sites for nucleation, N0, with three-dimensional, diffusion-controlled growth of clusters are critically examined and compared with experimental and computer-simulated data.
