Nonionic surfactants usually do not show affinity to proteins and they work via competitive surface and interfacial processes in abinary mixture. However, we show in this work...

The addition of multivalent counterions (Al3+, Mg2+) induces multilayer adsorption of ionic surfactants at interfaces. It is associated with strong wetting conditions, invoking...

This proposal presents to directly measure ¿bridging¿ of anionic surfactants on an anionic surface through multivalent ions from water under well-controlled conditions (pHs and...

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...

We request SANS beam time on LOQ to study the impact of multivalent counterions on the micellisation of alkyloxyethylene sulfate surfactants and alkyloxyethylene sulphate /...

We have previously shown that peptides such as G(IIKK)4I-NH2 (G4) can kill bacteria and inhibit cancer cell growth whilst remaining benign to mammalian host cells. We have also...

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)...

Adsorption of a charged polyelectrolyte onto an oppositely charged substrate is important for the understanding of many natural molecular events as well as for the development...

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...

Short peptide sequences consisting of hydrophobic and hydrophilic amino acid units are capable of self-assembly, leading interfacial adsorption and solution nano-aggregation....

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...

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...

Biosurfactants are becoming more commonplace in pharmaceuticals, vaccines and other forms of medicines. With the biobased economy growing substantially and pressure to reduce...

Polyunsaturated fatty acids (PUFAs) are essential dietary fats that have been proposed to reduce the risk of cardiovascular and auto-immune diseases, arthritis and cancer. PUFA...

This proposal constitutes part of our ongoing study towards understanding the adsorption of collagen based polypeptide and its interaction with ionic surfactants at the...

Lipid bicontinuous cubic phases are self-assembled three dimensional lattices, consisting of a single periodic bilayer interwoven by two independent water channels. They can be...
