Interdroplet attractive forces in AOT water-in-oil microemulsions formed in subcritical and supercritical solvents

Fundamental Studies and Applications of Supercritical Fluids

“…In addition, the rotational dynamics of their probe (perylene tetracarboxylate) was independent of fluid density. This observation was consistent with results from Johnston and co-workers and Smith and co-workers (61)(62)(63)(64)(65)72).…”

“…Steady-state solvatochromic techniques provide a reasonable means to study solvation processes in supercritical media (5,(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(43)(44)(45)(59)(60)(61)(62)(63)(64)(65)(66)(67)(68). But, unless the interaction rates between the solute species and the supercritical fluid are slow, these "static" methods cannot be used to study solvation kinetics.…”

Critical flocculation density of dilute water-in-CO2 emulsions stabilized with block copolymers

“…Since this study focuses on relatively large miniemulsion droplets, the effects of the adsorbed polymer layer on the Hamaker constant may be ignored, and the core-core interactions may be assumed to be those of pure water droplets dispersed in CO 2 [41]. The Hamaker constant, A 121 , for a water droplet (subscript 1) interacting with another water droplet across CO 2 (subscript 2) may be approximated using the following relationship [40],…”

Hydrogenation Reactions in Supercritical CO2 Catalyzed by Metal Nanoparticles in a Water-in-Carbon Dioxide Microemulsion

“…There has been much interest in recent years to exploit the properties of microemulsion phases in supercritical fluids (23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33). A reverse micelle or microemulsion system of particular interest is one based on C0 2 because of its minimum environmental impact in chemical applications.…”
