Mixtures of colloidal particles of essentially two different sizes are commonly used in technological applications such as film formation on surfaces, paper coatings, etc....

Amphiphiles derived from amino acids are important functional materials. The amino, carboxyl and side chain groups present in the chemical structure of amino acids provide wide...

This proposal constitutes part of our ongoing study towards understanding the solution aggregation of collagen based polypeptides and their interactions with model surfactants....

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...

Melanins are the major determinants of pigmentation of skin, hair and eyes in humans. These pigments originate from the tyrosinase-catalyzed oxidation of tyrosine, leading to...

Beta-cyclodextrins (b-CD) are well tolerated in humans without toxic side effects and present in several injectable drug formulations, due to their ability to form host-guest...

Cyclic peptide-polymer conjugates can readily self-assembly into long nanotubes, and are being extensively studied for drug delivery applications. Recently, using SANS and...

It is now well established that the addition of the trivalent counterion, Al3+, induces surface multilayer formation in a range of anionic surfactants, including SLES, MES and...

Aggregates of the cationic conjugated polyelectrolyte (CPE) HTMA-PFP with poly(vinyl alcohol) (PVA) will be studied in aqueous solutions using SANS. Previous fluorescence,...

Janus particles, bearing two distinct compositions on the surface of the same particle, have attracted much attention recently as a way to finely tune morphology and...

Lipopeptide surfactants are highly effective at reducing interfacial tension. However, there is a general lack of understanding of the relationship between their molecular...

We intend to study the phase behaviour of 2 cationic polythiophenes, P3MAHT and P3ImiHT, inthe presence of the perfluorinated surfactant (C8 chain) PFOS and its hydrogenated...

Proteasome plays an important role in the processing of antigenenic proteins for presentation by the MHC class I pathway. PA28 is an activator of the 20S proteasome, a large...

Latex is made from tiny polymer particles in water. Latex films are used in paints and to manufacture adhesives & inks. Latex is good for the environment, as it does not...

The aim of this proposal is to determine the thickness of a water layer surrounding colloidal particles dispersed in oil with changes in ionic strength. Recent work by our group...

Nanoparticles made of polymers containing fluorine have promising applications since magnetic resonance imaging using fluorinated contrast agents (19F MRI) enables enhanced...

Deep Eutectic Solvents (DES) are molecular mixtures with melting points below room temperature. DES share many features of ionic liquids (low vapour pressure, adjustable...

There are specific models about the influence of shear on mixtures that are distinctive from dspersions of unifom particles. Understanding the flow behaviour of mixtures of...

This proposal is part of a broad programme of collaborative research between RAL / Oxford and Unilever, using predominantly scattering techniques to investigate the nature of...

The aim of this experiment is to investigate the change in conformation of a chiral polymer dissolved in hexafluoroisopropanol as the temperature of the system is varied....
