Adsorption of tetraalkylammonium (R4N+) counterions into monolayers of surfac...
This proposal is to explore adsorption of tetraalkylammonium (R4N+) counterions into monolayers of surfactant anions (see Figure 1) at the air-water interface, as a function of... -
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... -
Adsorption of magnetic surfactants
Surfactants responsive to pH, temperature, CO2, and light are known, however, our recent work has shown, for the first time surfactants that are magneto-responsive, and also... -
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... -
Multi-catalyst ensembles - aggregation structure and selectivity
There is exciting potential for SANS to resolve an important problem in homogeneous catalyst chemistry. The Pd-chiral catalyst 1+ below has significant pan-industrial potential... -
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... -
Optimizing surfactants for CO2
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... -
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... -
A new approach to viscosity enhancement of oils and CO2
Due to the naturally low viscosity of liquid CO2 (0.1-1.0 cP pressure/temperature dependent) the CO2 is prone to ¿fingering¿, limiting the efficiency of CO2-EOR [1]. In order to... -
Magnetic self-aggregating ionic liquids (MSAILs)
This proposal is to explore aqueous phase structures with a new class of magnetic self-aggregating ionic liquids (MSAILs) (see Figures 2 and 3 below). The dilute micellar... -
Aggregation in ionic liquids
The aim of this experiment is to investigate surfactant aggregation in ionic liquids and also ionic liquid ¿ oil and ionic liquid ¿ water microemulsions via SANS. Contrast... -
Microemulsions stabilized by magnetic surfactants
Surfactant systems responsive to pH, temperature, CO2, and light are known. Our new work has shown for the first time, magneto-responsive surfactants (also being ionic liquids... -
Do hydrotropes stabilize, or destabilize, micelles?
The aim is to investigate and understand interactions of hydrotropes (primitive amphiphiles) with a new range of industrially important non-ionic surfactants, alkyl-capped... -
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.... -
Co-micellization of hydrotropes and surfactants
This proposal builds on recent work with hydrotropes alone (Langmuir, 2011, 27, 12346-12353); now co-micellisation of hydrotropes with surfactants will be investigated. The aim... -
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... -
Manipulation of the aggregate curvature in water/dense CO2 system
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... -
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...
