✦ Synopsis

The Laplace transformed diffusion equation is solved for finite diffusion in planar, cylindrical and spherical geometry with a Nemstian or an impermeable diffusion layer boundary condition. Analytical expressions are presented generalized as the Laplace transformed concentration to flux ratio at the electrode surface. The limiting behavior for a number of high and low frequency cases is derived. From these solutions the diffusion impedance for specific electrode reactions can be obtained.

To investigate reactive diffusion in nanosized spherical geometries, a clear model experiment has been designed. Thin film {Al/Cu/Al} and {Cu/Al/Cu} triple layers were deposited on tips of 25 nm apex radius and investigated by atom probe tomography (APT). At the interfaces within both samples, the g

Results are reported from uv-vis absorption measurements in the diffusion layers of planar, cylindrical and spherical electrodes. The reversible one-electron oxidation/reduction processes of N,N,N', N'-tetramethyl-p-phenylendiamine have been used as an example. Diffusion coefficients and formal rate
