Mixed surfactants for positive synergism in dense CO2
This proposal aims to explore a cheaper and more environmental-benign surfactant system for yielding efficient water/CO2 microemulsions. The new surfactants permit high... -
Mixed micelles with "green" surfactants
This proposal aims to explore aqueous phase structures and compositions of a series of mixed surfactants. Although standard surfactant mixtures have been extensively studied... -
Concentrated emulsions as proxy CO2 thickeners
The proposal aims to explore the oil-in-water (brine) high internal phase emulsion systems (HIPEs) formed by nonylphenol ethoxylate surfactants using contrast variation SANS... -
Photo-reactive surfactants for nanoparticle generation
The aim is to employ contrast variation CV-SANS to investigate structure in novel systems used to generate metal-containing nanoparticles on organic solvents by UV irradiation.... -
Mechanism of charging metal oxide colloids in non-polar solvents
Contrast-variation SANS (CV SANS) will be used to determine how surfactant inverse micelles interact with model metal oxide colloids. By using deuterated surfactant (D-AOT) with...
