FT-IR spectroscopic evidence of water/AOT/n-heptane and water/NaDEHP/n-heptane systems
Article Abstract:
The interaction of water with surfactants in the core of reversed micelles was examined using the Fourier transform infrared spectroscopy (FT-IR). The surfactants considered in the study were sodium bis(2-ethylhexyl) sulfosuccinate (AOT) and sodium bis(2-ethylhexyl) phosphate (NaDEHP). A comparative analysis between the two surfactants was conducted. It was observed that reversed micelles with encapsulated water molecules showed odd properties attributed to water interaction with the surfactants' polar headgroups.

Comparative study on the structure of reverse micelles. 2. FT-IR, (sup-1)H NMR, and electrical conductance of H(sub-2)O/AOT/NaDEHP/n-Heptane systems
Article Abstract:
The microstructure of mixed reverse micelles stabilized with surfactants of sodium bis(2-ethylhexyl)-sulfosuccinate (aerosol OT, or AOT) and/or sodium bis(2-ethylhexyl)phosphate (NaDEHP) has been studied by means of Fourier transform infrared spectroscopy. The presence of NaDEHP helps one dimensionl growth of aggregates and changes the morphology of droplets from sphere to ellipsoid, which markedly changes the conductance behavior of the mixed reverse micelles.

Three-dimensional periodic and fractal precipitation in metal ion-deoxycholate system: a model for gallstone formation
Article Abstract:
It has been possible to develop a three-dimensional model in which metal ions and deoxycholate ions are permitted to diffuse into each other in an agar-gel sphere and react to create concentric rings and fractal patterns. The rules of pattern formation in three-dimensional systems are not identical to those in one- and two-dimensional experiments.
