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... -
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... -

Commercial access. Agreed for 13th March 2013 -
Gels in CO2
The proposal aims to explore different self-assembly structures in CO2 with the focus of developing viscosity modifiers for supercritical CO2 (sc-CO2). This is part of a... -
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... -
Component Characterization
Time is required on Loq to study the bulk properties of commercial systems under shear. This time will come under existing NDA with Lubrizol. -
Organogels for applications in CO2
This proposal aims to explore organogel systems, like those recently decsribed1-3, but made from new CO2 philic surfactant-gelators. These have been synthesised to feature... -
Close control over microemulsion stability using blended solvents
The aim of this proposal is to investigate a novel approach to phase separation in microemulsions using careful choice of organic solvents, and appropriate mixtures.... -
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... -
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... -
Gold-loaded microgels
Recent results show that gold nanoparticles (Au-NPs) can be included into microgels (MGs). UV-visible spectra (Figure 1) suggest the original Au-NP sols retain their size and... -
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... -
Bi-disperse colloids: silica and microemulsions
Surprisingly little work has been done to gain understanding about the nature, stability and properties of nanoparticles dispersed in organic solvents (organosols). Recently... -
A structural evolution: hydrotrope-alkyl hydrotrope-surfactant
The aim of the proposal is to improve understanding about combinations of normal surfactants and hydrotropes. The systems of study are reference oil-water interfaces, provided... -
Mixed surfactants for dialable organogels
The idea is to be able to ¿dial-up¿ the length and properties of CO2-philic and organo-philic rod-like micelles. This proposal aims to explore mixed surfactant systems in... -
Solventless protein liquids: a novel form of biological matter
Solventless protein liquids (SPLS) represent a novel form of biological matter. Recently we reported on the preparation and properties of a solvent-free liquid protein based on...
