Metal organic frameworks (MOFs) are a particularly interesting class of three dimensional crystalline networks formed by the self-assembly of metal ions with organic ligands....

In recent years much progress has been made in the design of surfactants that are soluble in liquid CO2; hence these additives able to modify physicochemical properties...

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,...

This proposal aims to explore a cheaper and more environmental-benign surfactants for microemulsion formation in CO2; in other words, a low fluorine containing...

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...

Approved proposal under the ICRD Scheme Proposal ICRD0005

Surfactants ability to lower surface tension and act as solubilising agents is critical for their wide use in everyday products. An oily hydrocarbon (HC) "tail group" attached...

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...

The research topic is Low surface energy materials (LSEMs), and development of new hydrocarbon architectures as replacements for environmentally hazardous fluorocarbon...

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...

The proposal aims to explore water-in-CO2 (w/c) microemulsions with very promising hybridCO2-philic surfactants. The surfactants have been systematically synthesised...

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...

This proposal aims to expand knowledge about water-in-CO2(w/c) microemulsions by studying the ¿bending rigidity¿ of surfactant films, which has been frequently tested on normal...

One of the most commonly used supercritical fluids is carbon dioxide (scCO2) which is non-toxic, non-flammable, abundant and has an easily accessible critical point. An...

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...

This proposal aims to explore optimal fluorine (F) content and chain architecture in triple-fluorocarbon (FC)-tail surfactants used as CO2-philic solubilizers for water-in-CO2...

Recurring infection following dental interventions such as fillings is the most common reason for failure, leading to further treatments including root canal therapy, where the...

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...

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...

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...
