Interfacial interaction and prenucleation at liquid-Al/γ-Al₂O₃{1 1 1} interfaces

Interfacial Rheology of Gas/Liquid and Liquid/Liquid Interfaces

An interfacial shear rheometer for stressand strain-controlled measurements at liquid interfaces is outlined. Experimental data are reported for the surfactant sorbitan tristearate on κ-carrageenan subphases. A setup combining interfacial rheometry with Brewster-angle Microscopy for realtime imaging of the interface is presented. INTRODUCTION Dynamic processes involving deformable fluid interfa...

Interfacial Solvation and Excited State Photophysical Properties of 7-aminocoumarins at Silica/liquid Interfaces

Title of Document: INTERFACIAL SOLVATION AND EXCITED STATE PHOTOPHYSICAL PROPERTIES OF 7-AMINOCOUMARINS AT SILICA/LIQUID INTERFACES Debjani Roy, Ph.D, 2010 Directed By: Professor Robert A. Walker, Department of Chemistry and Biochemistry The properties of solutes adsorbed at interfaces can be very different compared to bulk solution limits. This thesis examines how polar, hydrophilic silica sur...

Hydrogen evolution at liquid-liquid interfaces.

Blowing bubbles: Hydrogen evolution by proton reduction with [(C(5)Me(5))(2)Fe] occurs at a soft interface between water and 1,2-dichloroethane (DCE). The reaction proceeds by proton transfer assisted by [(C(5)Me(5))(2)Fe] across the water-DCE interface with subsequent proton reduction in DCE. The interface essentially acts as a proton pump, allowing hydrogen evolution by directly using the aqu...

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...
