W/CO2 nanodispersions as an energy-saving nanoreactor separable by pressure a...
Recent studies implied an unusual headgroup (HG)-free, fluorocarbon (FC) surfactant Nohead FC6-HC4 to form stable, W/CO2 nanodispersions (W/C NDs). With the unusual surfactant... -
Exploring CO2-philic/ CO2-phobic amphiphiles, cross-linkers and HC-polymers f...
Over the last two decades, many polymers have been tested to increase CO2 viscosity for applications in enhanced oil recovery using CO2 (CO2-EOR). Unfortunately, conventional... -
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... -

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... -
SANS DETERMINATION OF CO2 ABSORPTION INTO SURFACTANT STABILISING LAYERS
Recent SAXS measurements have indicated that CO2 can dramatically swell the surfactant layer in w/o microemulsions formed in CO2-swollen oils and also enhance solubilisation...
