This proposal is concerned with determining variations in the high pressure crystallographic and magnetic structure of LaFeO3. LaFeO3 is a characteristic example of...

CaSiO3 perovskite is the third most abundant mineral in the Earth's lower mantle; it also occurs as a major phase at lower pressures and temperatures in subduction zones, where,...

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...

This proposal aims to explore cheap and environmental-benign cosurfactants (or cosolvents) for yielding CO2-philic hydrocarbon surfactant/water/CO2 microemulsions (W/CO2...

This proposal explores headgroup-free, fluorocarbon-hydrocarbon hybrid compounds able toform viscous elongated aggregates in supercritical CO2 with the aim of improving...

This proposal involves manipulating the curvature of aggregated polar materials in supercritical CO2 (scCO2) by tuning the mixing ratio of fluorocarbon (FC) and hydrocarbon (HC)...

This proposal involves manipulating the curvature of aggregated polar materials in supercritical CO2 (scCO2) by tuning the mixing ratio of fluorocarbon (FC) and hydrocarbon (HC)...

This proposal is to probe the gel structure with High Pressure SANS (HP-SANS) using an in-line pressure cell. The ability to control the properties of supercritical CO2,...

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...

For the last two decades, many polymers have been tested to increase CO2 viscosity for enhanced oil recovery using CO2 (CO2-EOR). Unfortunately, conventional HC-polymers were...

Recent SANS studies of an unusual headgroup-free surfactant (Nohead FC6-HC4) produced data that implied the formation of W/CO2 microemulsions (MEs) at a particular pressure (P)...

This proposal is concerned with determining variations in the high pressure structure of LaCoO3 and observing changes within this as the material undergoes some well...

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...

Over the last two decades, many polymers have been tested to increase CO2 viscosity for applications in enhanced oil recovery using CO2 (CO2-EOR). Unfortunately, conventional...

CO2 foams can be formed in water/carbon dioxide (W/CO2) mixtures with the aid of W/CO2 interfacially active hydrocarbon surfactants and surface treated silica nanoparticles...

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...

Recent studies implied an unusual headgroup (HG)-free, fluorocarbon (FC) surfactant Nohead FC6-HC4 to form stable, W/CO2 nanodispersions (W/C NDs). With the unusual surfactant...

We use SANS to study synthesis of interpenetrating polymer network in supercritical CO2 in situ at sans2D. The initial system contains an inorganic polymer network, hydrophilic...

In recent years, there has been an enormous interest in the study of surfactants for supercritical CO2 (scCO2). One important potential application of these materials is in...
