Thin Layer Chronoamperometry

The common electroanalytical method of exhaustive amperometric detection in a microscopic thin layer is modelled as a 1D-symmetric diffusion problem. The simulated result agrees with the analytical Cottrell equation at short times, and deviates as expected at long times when the diffusion layer spans the thin layer cell.

Simple Diffuse Double Layer

Simplified version of the "Diffuse Double Layer" model to demonstrate the coupling of Electrostatics to Transport of Diluted Species under conditions of: - zero current - cell size much greater than Debye length These conditions are common in many applications where users may want to solve the Nernst-Planck-Poisson equations to predict double layer structure in a system. Compared to the Model ...
