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... -
DYNAMICS OF SURFACTANTS IN LUBRICATING OILS
In a recent series of successful experiments at PSI and ISIS we were able to demonstrate the possibility of measuring the rate of transfer of a small molecule (allyl alcohol)... -
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... -
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... -
SANS study of engine oil gelation
Metal carbonate particles dispersed in dodecane and stabilised with alkyl salicylate surfactants have been shown to aggregate when trace water is added. We have found that... -
Particle formation mechanism for overbased calcium carbonate particles stabil...

Are hydrotropes a unique class of solutes?
The aim is to improve understanding of solution properties and aggregation of hydrotropes and alkyl¿hydrotropes, and the relationship with common surfactants. Although they are... -
Structural evolution - hydrotrope to surfactant
The aim is to improve understanding about combinations of normal surfactants and hydrotropes in aqueous systems. This is to support our recent work with but in non-aqueous... -
SANS study of self assembled structures formed from salicylate surfactant in ...
We wish to determine a structure we have observed in a dodecane/surfactant/water system. Initial experimentation has suggested the possibility of spontaneous formation of a... -
Surface layers in organosols
This research project addresses an overlooked, but fundamental issue of colloid science: surfactant adsorption dynamics at nanoparticle-organosolvent interfaces. Adsorption of...
