Catalytically driven colloidal patterning and transport

Article Abstract:

An electrokinetic model, which explains the details of the convention and pattern formation phenomenon, developed in conjunction with experiments, is described. This model enables the measurement of reaction kinetic parameters that are otherwise difficult to obtain and also serves as a platform for the modeling of other catalytic redox systems and systems with broken symmetries.

Quasi-reversible faradaic depolarization processes in the electrokinetics of the metal/solution interface

Article Abstract:

The consequences for the electrokinetic properties of metallic surfaces in the presence of a quasi-reversible redox couples are analyzed. The corresponding formalism completes the rigorous basis for a quantitative interpretation of electrokinetic features of electron conducting surfaces depolarized by irreversible, quasi-reversible, or reversible bipolar faradaic processes.

Series approach to modeling ion size effects for asymmetric electrolytes in the diffuse double layer

Article Abstract:

The theory of the diffuse layer for asymmetric electrolytes is reevaluated with emphasis on the effects of ion size on the diffuse layer potential drop and differential capacity. The series approach accurately describes potential drops and differential capacities of the diffuse layer for 2:1 and 1:2 electrolytes for the chosen assumptions.
