Coupling of lateral electric field and transversal faradaic processes at the conductor/electrolyte solution interface

Article Abstract:

A quantitative theory was presented for the bipolar behaviour of conducting planar surfaces in a thin-layer cell of a type commonly used in electrokinetic studies. The lateral current density distribution in the cell, as dictated by the externally applied field in the solution, is formulated for the situation in which depolarization of the interface arises from transversal electron-transfer processes that occur at the two sides of the conducting surface.

Rigorous analysis of reversible faradaic depolarization processes in the electrokinetics of the metal electrolyte solution interface

Article Abstract:

A theoretical analysis for the faradaic depolarization processes occurring at metallic surfaces in an electroactive electrolytic solution is proposed. The findings show that it is possible to electrokinetically probe double layer properties of metals in the presence of a reversible redox couple, provided any accompanying bipolar depolarization is well understood and taken into proper account.

Conductivity studies of nanostructured TiO2 films permeated with electrolyte

Article Abstract:

Charge transport in nanostructured TiO2 films permeated with electrolyte is studied, using the temperature-dependent conductivity and electron accumulation measurements. A technique is developed from which activation energies of conduction, electron accumulation, and mobility in nanostructured semiconductor electrodes can be determined.
