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...

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...

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...

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...

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...

The proposal aims to explore water-in-CO2 (w/c) microemulsions with very promising hybridCO2-philic surfactants. The surfactants have been systematically synthesised...

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...

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...

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...

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...
