Drag reduction methods at solid-liquid interfaces

Potential-modulation spectroscopy at solid/liquid and liquid/liquid interfaces.

Potential-modulation spectroelectrochemical methods at solid/liquid and liquid/liquid interfaces are reviewed. After a brief summary of the basic features and advantages of the methods, practical applications of potential-modulation spectroscopy are demonstrated using our recent studies of solid/liquid and liquid/liquid interfaces, including reflection measurements for a redox protein on a modi...

Adsorption of Proteins at Solid-Liquid Interfaces

This paper concisely rev iews the general principles underlying protein adsorption from aqueous so lution onto a solid surface. The discussion includes the various stages of the adsorption process, i. e., transport o f the protein molecules towards the su rface, the absorbed amount under equilibrium conditions, desorption andreadsorption. Among the interactions that determine the overall protei...

Scanning Tunneling Microscopy at Solid-Liquid Interfaces

Electrostatic Potentials at Solid/Liquid Interfaces*

This review deals with electrostatic potentials within solid/electrolyte interfaces. The electrostatic potentials of several planes are defined and discussed: the inner surface potential affecting the state of charged surface species due to interactions with potential determining ions (Ψ0), the potential affecting the state of associated counterions (Ψβ), the potential at the onset of diffuse l...

Surfactant aggregates at rough solid-liquid interfaces.

We demonstrate improved atomic force microscopic imaging of surfactant surface aggregates, featuring an increase in the topography contrast by several hundred percent with respect to all previous studies. Surfactant aggregates on rough gold surfaces, which could not be imaged previously because of low resolution, display substantially different morphologies when compared with atomically smooth ...
