Magnetic ionic liquid surfactants
This proposal is to explore the magnetic properties and molecular dynamics of a new class of magnetic ionic liquid surfactants1 (MILSs) (see Fig. 1). The MILSs investigated here... -
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... -
Nonfluorous Cosurfactant/Hyperbranched Surfactant Mixtures for W/CO2 Microemu...
This proposal aims to explore cheap and environmental-benign cosurfactants (or cosolvents) for yielding CO2-philic hydrocarbon surfactant/water/CO2 microemulsions (W/CO2... -
Mixed micelles with green surfactants
This proposal aims to explore aqueous phase structures and compositions of a series of mixed surfactants. Although standard petrochemically-derived surfactant mixtures have been... -
Effect of the MOF pore structure upon coordinatively unsaturated Cu centres.
Metal-organic frameworks are an exciting class of porous and crystalline materials exhibiting exceptional sorption properties. The growing interest in the community lies in the... -
Is there a CMC for surfactants in non-aqueous solvents?
The aim of this project is to use SANS to determine if a critical micelle concentration (CMC) exists for the formation of inverse micelles in non-polar solvents. The CMC is a... -
Surfactant aggregation in magnetic ionic liquids
This proposal aims to explore aggregation behavior of common surfactants in magnetic ionic liquids (MILs) and to investigate the effect of a magnetic field on aggregate size,... -
Tuning micellar interfacial curvature in CO2 by small molecule additives
This proposal aims to explore co-surfactants, as additives with CO2-active surfactants, for elongating reversed micelles in dense CO2 by using high-pressure small-angle neutron... -

In-situ Neutron Diffraction Investigation on Creep-Resistant Ferritic Superal...
We have developed a new class of ferritic steels strengthened by hierarchical precipitates (HPs) of Ni2TiAl/NiAl or a single precipitate (SP) Ni2TiAl for applications as... -
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... -
Interfacial structure in self-assembling conjugated polymer photovoltaic devices
The proposal aims to determine the degree of interfacial mixing and roughness at an interface between two conjugated polymers, as part of a broder program to understand how to... -
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... -
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... -
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... -
Misfit and Misfit Release in Co-Co3(Al,W) Superalloys
The effect of alloying additions (Ni, Fe, Cr, Ta, Mo, V, Ti, Si) on the misfit of developmental Co-Al-W alloys will be examined using Polaris. The Co3(Al,W) precipitate phase...
