Investigation of cosolvent effects on the solvation of AOT reverse micelles in supercritical ethane
Article Abstract:
The solvation and penetration of benzene and methylene chloride into the surfactant tail regions of sodium bis(2-ethylhexyl) sulfosuccinate (AOT) reverse micelles in supercritical ethane has been studied with a variety of spectroscopic methods. Phenol blue was discovered to exist in the surfactant tail region of the AOT reverse micelles. Its wavelength of maximum absorption was discovered to be sensitive to changes in the ethane continuous phase. There is also an enhanced red shift on the absorption spectra of blue phenol from the penetration of the cosolvents.

Solvent effects on copper nanoparticle growth behavior in AOT reverse micelle systems
Article Abstract:
The results of variations in the bulk solvent type and the addition of cosolvents on the growth rate of metallic copper nanoparticles, which are produced through the reduction reaction within anionic surfactant sodium bis(2-ethylhexyl) sulfosuccinate (AOT) reverse micelles is presented, where the metallic copper particles were characterized by ultraviolet (UV) spectroscopy and TEM microscopy.

Tunable solvation effects on the size-selective fractionation of metal nanoparticles in CO(sub 2) gas-expanded solvents
Article Abstract:
A method for precise, rapid, pressure-tunable, size-selective nanoparticle precipitation and redispersion with tunable CO(sub 2) gas-expanded liquids is developed. It is found that as the solvent temperature is increased, an increased in CO(sub 2) pressure is required to completely precipitate all the nanocrystals from solution.
