The puroindoline (PIN) and purothionin (PTH) families of polypeptides both occur in wheat and are implicated in antipathogenic defence mechanisms, and of interest for potential...

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...

The overall objective is to model the amount and composition of adsorbed mixtures of three types of zwitterionic surfactant and two charged surfactants at the silica/water...

Cubosomes and hexosomes are particles with internal liquid crystal structures of the bicontinuous cubic or reverse hexagonal nanostructures respectively. The nanostructure...

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...

Tolaasin is a lipodepsipeptide (lipo = hydrophobic side chain, depsipeptide is an amino acid ring closed in a particular way) produced by strains of Pseudomonas tolaasii, and it...

We propose to continue laser spectroscopy measurements of the muonium (Mu-) centres in n-type doped silicon carbide. Scanning a wide wavelength range, and changing the relative...

This proposal aims to investigate how the curvature of surfactant assemblies in water/dense CO2 systems can be tuned via the design and mixing of CO2-phillic surfactants. One...

Our goal is to understand the role of POPS, a lipid component only found in the inner leaflet of plasma membrane, in the organization of cholesterol in cell membranes. Our...

We are unravelling the solution structures of the Fab and Fc fragments in the IgA antibody family important in mucosal immunology. Having completed the structures for IgA...

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

It is the aim of the proposal is to perform neutron reflectivity (NR) studies combined with contrast variation to determine the structure of phospholipid monolayers on a...

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

Here we propose to study the local structure of sodium in standard organic carbonate electrolytes for sodium ion batteries. Three different electrolytes are chosen to study; a...

Amino acid based surfactants have been known for many years but so far few detailed studies have been carried out on their properties. We are using amino acids extracted from...

We request two days’ beam time on SANS2D for the study of radiation-grafted anion-exchange membranes, both dry and hydrated under different ratios of D2O/H2O. These materials...

The present application focuses on the determination of possible differences in pottery production methods during the Neolithic Period . Samples of coarse grain temper (organic...

In this experiment MgH_2 impregnated into active carbon will be investigated through IINS. Since it is known that the enthalpy of formation of a material is lowered by...

Active pharmaceutical ingredient (APIs) are frequently delivered to the patient in the solid-state as part of an approved dosage form (e.g., tablets, capsules, etc.). Drug...

The effects of electrolytes on SLES3, C12E8 and LAS4 has been extensively studied, especially the effect on the critical micelle concentration of each surfactant. We wish to...
