Progress in the development of nano-sized hybrid therapeutics and nano-sized drug delivery systems - "nanomedicines" - over the last decade has been remarkable. One key...

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...

We request NR beam time on SURF to study the impact of multivalent counterions on the surface adsorption of alkyloxyethylene sulfate surfactants and alkyloxyethylene sulphate /...

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

The Outer Membrane (OM) is found in bacteria which cause plague, cholera & Legionnaire’s disease. It is important as; a barrier to antibiotics & the site of...

Hydrophobins, hfb2, are secreted fungal proteins, which are strongly surface active and possess powerful emulsion and foam stabilising properties. Understanding their...

Although surfactant detergency is well understood above 30 C, actions of surfactants below 30 C are not well established. In the era of energy saving and environment caring, we...

We propose to make neutron reflectivity measurements of the weak polyelectrolyte, poly(dimethy amino ethyl methacrylate), grown from two different surface densities of initiator...

Nonionic surfactants usually do not show affinity to proteins and they work via competitive surface and interfacial processes in a binary mixture with protein. However, we show...

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

Recent research has demonstrated the potential of nanosized delivery systems for routine use in many diseases, eg cancer, viral diseases and rheumatoid arthritis [1,2], due to...

The understanding of the plant wax-surfactant interaction process is crucial to the development of more effective pesticide and fungicide formulations, essential for improving...

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

The interface of CaCO3 (calcite) and oil is of paramount importance in a number of key academic and industrial areas, not least oil recovery. Neutron reflection has proved to be...

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...

The gram-negative bacterial membrane is of extreme medical importance. The two main lipid components of the outer membrane are lipopolysaccharides (LPS's) and DOPE. We will...

This proposal concerns the adsorption behaviour of an electron-transfer protein, cytochrome c, on modified electrode surfaces. Cytochrome c plays an important role in...

Surfactants usually form a single layer of molecules at the surface of water. We have shown that under certain conditions more than one layer may form. in which case the system...

Polymers adsorbed or otherwise attached to interfaces provide an extremely powerful tool to control the forces that act between interfaces. The functionality of these attached...

The interface of CaCO3 (calcite) and water or oil is of paramount importance in a number of key academic and industrial areas, not least oil recovery and scale deposition in...
