Micellization in H/F-Carbon surfactant mixtures used in fire-fighting foams
The aim is to probe the micellar compositions of fluorocarbon/ hydrocarbon mixtures used in commercial fire-fighting foam formulations (Figure 1) using contrast variation SANS.... -
Structure in model fire-fighting foams
The aim is to probe the structure in and of foams for three common industrial fluorotelomer surfactants used in fire-fighting foam formulations using SANS. The structure of... -
Worm-like reversed micelles with a CO2-philic surfactant
Hydrotropes (Figure 3 A-C) are known viscosifying agents with surfactants in organic solvents1 and interestingly now in supercritical CO2 (scCO2)5. The mechanism is... -
CO2 foams stabilized by W/CO2 interfacially active hydrocarbon surfactants an...
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... -
Magnetic vesicles: structure and composition
This proposal aims to explore composition behaviour of vesicles formed by aqueous mixtures of magnetically active cationic liquid surfactants (MILSs, Figure 3) with the... -
Aggregation of new silicon containing surfactants (NOT silicone surfactants)
The results from this experiment will develop alternatives to controlling surface tension through the design of 21st century surfactants (better performance at lower... -
HC-polymer 3D-network conjugated by hydrocarbon-fluorocarbon core/shell aggre...
For the last two decades, many polymers have been tested to increase CO2 viscosity for enhanced oil recovery. Unfortunately, HC-polymers were found to be inactive for the... -
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...
