Analytical expressions were derived for the harmonics of the current response to an ac voltage input, when the rate-determining process is a redox reaction of a couple confined to the electrode surface. Some input/output phase relations such as funct

Direct electron transfer to putidaredoxin (Pdx) in solution from bare gold and mercaptoethylamine-modified gold electrodes was studied by cyclic voltammetry. The current response of Pdx at a bare gold electrode was irreversible and highly unstable. T

A general equilibrium model for a class of biochemical reactions was formulated, using the formalism of binding polynomials for the evaluations of the various species. Thermodynamic equilibrium constant was obtained from the observed equilibrium tota

Discontinuous Bessel integrals are applied to a boundary value problem related to chronoamperometry, with zero concentration at the disk satisfied on the average and the zero flux at the shroud satisfied approximately only. Current functions are deri

The charge-time relation for double potential-step large-amplitude chronocoulometry was developed for a system with electrodeposition of the product. The model assumes that the concentration of the product near the electrode cannot be larger than the

A finite elements digital simulation of chronoamperometry with polymer-coated electrodes is presented. The model takes account of mass transport by diffusion and migration, and the effects of the uncompensated resistance and capacitance of the system
