Water immobilization at surfactant interfaces in reverse micelles
Article Abstract:
A study was conducted to analyze the mobility of water in water/aerosol OT/isooctane reverse micelles through polar solvation dynamics measurements. Ultrafast, time-resolved fluorescence-upconversion spectroscopy was utilized to carry out the analysis. The femtosecond fluorescence-upconversion spectrometer was utilized to obtain the fluorescence signals. Experimental results indicated that the interactions of water with the surfactant headgroups in reverse micelles eliminated bulk-like solvent dynamics.

Mechanism of lecithin adsorption at a liquid/liquid interface
Article Abstract:
The adsorption of L-alpha-lecithin (dipalmitoyl) at the water/1,2-dichloroethane interface was studied by cyclic voltammetry. It was found that the voltammetric peak in acidic medium corresponds to the desorption of the protonated form of lecithin.
