Polyions and biogenic polyamine are ubiquitous in many important biochemical functions. We propose here to use neutron reflectivity to investigate their potential to induce and...

Surfactants usually form a single layer of molecules at the surface of water. We have shown, surprisingly, that under certain conditions more than one layer may form. When this...

This proposal constitutes part of our ongoing study towards understanding how keratin, an important protein component of hair and skin, interacts with ionic surfactants using...

Hydrophobins are secreted fungal proteins in the form of small lipopetide biosurfactants. They are strongly surface active and self assemble at interfaces and in solution. This...

Understanding the fundamental aspects of the surface adsorption and self-assembly of biosurfactant and biosurfactant / conventional surfactant mixtures is a major challenge for...

We have now established that multilayering at the air-water interface is a widespread phenomenon brought about by multivalent ions, whether polyelectrolyte, oligoelectrolyte or...

SANS will be used to determine the structure of nanotube dispersions formed by H-bond stacking of cyclopeptides coated with a sheath of stabilizing polymer. Cyclopeptide...

The methyl ester sulfonate. MES, and ethyl ester sulfonate, EES, are representative of a promising group of anionic surfactants which have the potential for improved performance...

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

Physical developer (PD) is a latent fingerprint development technique that is highly effective on paper and related surfaces, notably banknotes. The process exploits a redox...

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 spontaneous formation of multilayer structures at surfaces and interfaces from self-assembly in mixed surfactant and in polymer / surfactant mixtures are being increasingly...

Gemini-like and oligomeric-like surfactants can be constructed by single-chain or gemini surfacants with connecting molecules through noncovalent binding without complicated...

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

Surfactants have been widely used in cosmetics, detergents and pharmaceutical industries. These applications are always accompanied by surfactant-induced skin irritation which...

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

Hydrophobins are secreted fungal proteins and are small lipopeptide biosurfactants. They are strongly surface active and self-assemble at interfaces. Their unique film forming...

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...

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...
