TL;DR: The theory of the potentiostatic current transient for three-dimensional multiple nucleation with diffusion controlled growth is discussed in this paper, where the termination of the nucleation process by the expansion of diffusion fields is considered, as well as deviations from randomness observed in the distribution of nuclei on the electrode surface.

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, the early stages of metal deposition are controlled by a nucleation process, and the potentiostatic growth transients are in accord with a process of instantaneous nucleation and subsequent hemispherical growth, although the observed concentration dependence is at variance with that predicted by existing theories.

TL;DR: In this paper, a series of simulations has been made for 108 dipoles interacting through the Stockmayer potential with μ* = 1·0, ρ* = 0·8, and a variety of summation methods has been used; all lead to similar thermodynamic properties and diffusion coefficients but the autocorrelation function of the dipole moment of a spherical region varies considerably according to the summation method used.

TL;DR: In this paper, microscopically small electrodes were used to study the kinetics of homogeneous redox reactions and the heterogeneous electrochemical nucleation of metals, and the results showed that the mass transfer to exposed areas of <10−6 cm2 gives rise to very high rates of mass transfer, which allow steady-state fluxes to be determined without external control of convection.
