Clupeine is isolated from herring and is an example of a protamine, which are cationic antimicrobial peptides occurring in the sperm cells of some fish. Protamines are active...

Of concern to the bioprocessing industry is the manner in which polysorbates included in solution formulations of antibodies affect the kinetics and equilibrium state of...

Our first completed photo-musr experiment on 6,13-bis(tri-iso propylsilylethynyl) pentacene (TIPS-Pn) has recently been accepted for publication. We observed a significant...

Chloride Intracellular Channels (CLICs) are a family of 6 proteins that have in common a C-terminal CLIC module and chloride-selective ion channel activity. CLIC1 is a 241...

As part of a project concerning the fate of nanoparticles in the body we have been studying the kinetic and competitive (or cooperative) aspects of protein adsorption. HSA is...

In this proposal we investigate the adsorption of the key dispersant additive, sodium polyacrylate, used in colloidal systems using neutron reflection on aluminium oxide, with...

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...

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) of Gram-Negative bacteria (GNB) is an asymmetric structure which contains complex lipids known as lipopolysaccharides (LPSs) on the outer surface. LPSs...

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

Foam stability, appearance and functionality is governed by the thin liquid films between foam bubbles. These films are stabilised by surface active molecules (surfactants and...

An experiment performed on INTER last year found extreme non ideal mixing between C12E8/SLES3 at the air water interface: this feature became more extreme as the temperature...

Lipopeptide surfactants are a group of interesting biosurfactants due to their natural origin and their high effectiveness at reducing interfacial tension. However, there is a...

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...

In this part of the proposed work, we wish to explore how antibiotics and antimicrobial peptides interact with model lipid bilayers in the form of a supported lipid bilayer,...

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

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...

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

The spontaneous selfassembly of nanoparticles (NP) at liquid-liquid interfaces is a phenomenon present in nature and relevant for many applications, such as, emulsion...
