Surfactant ionic liquids as tuneable structured media
This proposal aims to explore aqueous phase structures of a new range of ionic liquid surfactants (IL-surfs). These IL-surfs have interesting potential applications as reaction... -
Nonfluorous Cosurfactant/Hyperbranched Surfactant Mixtures for W/CO2 Microemu...
This proposal aims to explore cheap and environmental-benign cosurfactants (or cosolvents) for yielding CO2-philic hydrocarbon surfactant/water/CO2 microemulsions (W/CO2... -
Micellar modifiers for CO2
This proposal focuses on a new approach to the formation of rod-like micelles in supercritical CO2 (scCO2). Recent successful high-pressure SANS (HP-SANS) results have shown for... -
Opening up microemulsion phases in CO2
New types of water-in-CO2 microemulsions using mixed surfactant systems will be investigated by high-pressure SANS (HP-SANS). Exciting new results (see report on RB820030) have... -
Rod-like micelles as CO2 fluid thickeners
Using LOQ, we have recently shown that self-assembly of fluoro-sulfocuccinate surfactants is indeed a viable approach to promote viscosity enhancement in liquid CO21 (Rod-like... -
Optimizing surfactants for CO2
This experiment addresses an important, and still unresolved, question in the field CO2-philic surfactants: what is the minimum fluorine content necessary to obtain a CO2-philic...
