Mixing CO2-philc surfactants and hydrotropes as a new approach to control vis...
One application where liquid CO2 has found success is enhanced oil recovery (CO2-EOR) of crude oil from porous rocks. However, a significant disadvantage of using CO2 in EOR is... -
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... -
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... -
Viscosity modifiers for CO2
There is a well-documented track record of research into water-in-CO2 (w/c) microemulsions. Using newly discovered CO2 compatible surfactants, the next step is to explore... -
Manipulation of the aggregate curvature in water/dense CO2 system
This proposal aims to investigate how the curvature of surfactant assemblies in water/dense CO2 systems can be tuned via the design and mixing of CO2-phillic surfactants. One... -
Polymer-induced critical pase separation
This proposal concerns a novel approach to phase separation in self-assembling colloidal systems. Microemulsions can be readily formulated to display critical-type phase... -
Optimising chemical structure of CO2-philic hybrid surfactants for stabilisin...
The proposal aims to explore water-in-CO2 (w/c) microemulsions with very promising hybridCO2-philic surfactants. The surfactants have been systematically synthesised... -
Surfactant mixtures in CO2
Studies by the Bristol group, and elsewhere [1, 2], have shown that highly branched hydrocarbon chains is the key factor for generating effective non-fluorous CO2 philic... -
CO2 foams stabilized by W/CO2 interfacially active hydrocarbon surfactants an...
CO2 foams can be formed in water/carbon dioxide (W/CO2) mixtures with the aid of W/CO2 interfacially active hydrocarbon surfactants and surface treated silica nanoparticles... -
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... -
New CO2-philic surfactants
The proposal aims to explore water-in-CO2 (w/c) microemulsions with new, very promising hydrocarbon surfactants. The compounds are generated using standard chemistry1 but with...
