Theory of the voltammetric response of electrodes of submicron dimensions. Violation of electroneutrality in the presence of excess supporting electrolyte
TL;DR: In this article, the shady state voltammetric behaviior of spherical electrodes of nanometer dimensions (1 and 10 nm) is computed by numerical solution of the Kernst-Planch and Poisson equations, showing that the reversible oxidation or reduction of an electroactive species, assumed to be present in solution at millimolar concentrations, is strongly affected by the electric field from the electrode surface, even in the presence of a large excess quantity of supporting electrolyte (0.5 M).

TL;DR: The results obtained here illustrate selectivity of the monolayer electrodes to electroinactive electrolyte anions, which participate indirectly in the electrode reaction, in addition to the previously established selectivity to electroactive cations and anions.

Electrochemistry in organic solvents without supporting electrolyte using platinum microelectrodes
TL;DR: In this article, the shape of the voltammogram is distorted by the ohmic iR drop, and a two-electrode, rather than a potentiostated three-electron measuring system, is recommended to minimize noise.
