An investigation of phase transfer catalysis employing quantitative structure-activity relationships
… Analysis of the model in the context of an interfacial mechanism led the hypothesis that the largest differences in catalyst activities were due to the sum of the interfacial adsorption and desorption rate constants. This hypothesis was tested by comparing the rate constants for the …

Gold Nanoshells: Synthesis and Applications to In Situ SERS
… is a powerful technique for probing molecular adsorption and reaction at the solid-liquid interface due to its very high surface sensitivity, wide applicable frequency range, and relative insensitivity to water. However, a low SERS activity and poor uniformity of roughened Au electrodes hinder …

Microvortices In Droplets: Generation & Applications
… phenomena--sedimentation of particles and interfacial adsorption of proteins--to concentrate both types of species at the rear of the droplet, where they can be extracted from the drop. In the latter case, the protein localization at the rear of drop reduces the interfacial tension locally …

Direct Force Measurements on the Colloidal Scale: From Modified Electrodes to Particle Manipulation
In this thesis the interfacial surface forces and mechanical properties of thin films have been studied by the colloidal probe technique. One central point is the combination of direct force measurements with an electrochemical setup in order to tune interfacial properties of an electrode modified …
