Adsorption of Rod-Shaped Surface-Active Particles at Liquid-Liquid Interfaces

Adsorption of microstructured particles at liquid-liquid interfaces.

The solid particles are adsorbed at interfaces and form self-assembled structures when the particles have suitable wettability to both liquids. Here, we show theoretically how the microstructure on the particle surface affects their adsorption properties. The physical properties of the interface adsorbing a particle will be described by taking into account the surface roughness due to the micro...

Adsorption of Nonspherical Particles at Solid/Liquid Interfaces

Localized adsorption of nonspherical particles at solid/liquid interfaces was analyzed theoretically. Aproximate models for calculating interactions between particles and interfaces as well as between particles were discussed. It was demonstrated that for convex particles the Derjaguin model can be used for small separations, whereas for larger separations the equivalent sphere approach proved ...

Universal emulsion stabilization from the arrested adsorption of rough particles at liquid-liquid interfaces

Surface heterogeneities, including roughness, significantly affect the adsorption, motion and interactions of particles at fluid interfaces. However, a systematic experimental study, linking surface roughness to particle wettability at a microscopic level, is currently missing. Here we synthesize a library of all-silica microparticles with uniform surface chemistry, but tuneable surface roughne...

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...
