N-acyl amino acids are promising anionic amphiphilic molecules, which consist of a linear aliphatic chain (hydrophobic tail) and an amino-acid residue (polar head). Although...

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...

In this proposal we wish to continue our current work on mesostructured inorganic films in largely ethanolic solutions, containing limited amounts of water. Transition metal...

We grafted 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer brush from the silicon wafer surface through Cu (0) mediated controlled radical polymerization (CuCRP) to mimic...

Neutron reflection (NR) is well established for studying molecular films such as lipid monolayers. Its high depth resolution combined with deuterium labelling can determine the...

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

The current project aims at elucidating how bile salts (BS) structure influences their interfacial behaviour and their impact on fat digestion. Neutron reflectivity (NR) is the...

Mitochondria are not only the powerhouse of the cell, but are also involved in cellular suicide via apoptosis (programmed cell death). The mitochondrial apoptotic pathway is a...

We propose to develop a new and generic, multi-probe technique to characterize the mass, and changes in mass, of material probed in a NR experiment. This methodology will be...

Migration and segregation of small molecules in complex polymer matrices is relevant to a huge range of industrial problems which we aim to address via a coordinated series of...

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...

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...

We have developed an experimental approach using a buried magnetic layer to provide contrast in systems consisting of complex biomolecular layers tethered to gold surfaces. This...

Oligo(ethylene glycol) self-assembled monolayers (SAMs) effectively prevent the adsorption of proteins from biological media. Despite the importance of this effect for...

We wish to make specular NR measurements on fluorophore functionalization of amine-functionalized polypyrrole (PPy-NH2) films. The critical issue is film penetration of solution...

gemini surfactants are essentially two surfactants joined by a linking chain. We have extensively explored cationic geminis at the air/water interface and they exhibit a range...

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...

The spin Seebeck effect is a relatively new phenomenon that could be harnessed for waste heat recovery. Its advantages lie with a new device architecture (compared to...

This proposal seeks to identify and characterise the adsorption of primary linear amides that adsorb to the surface from the bulk of a polymer melt. These layers are...

The main purpose of the experiment proposed here is to study the effects of thermalisation on Artificial Spin-Ice (ASI) systems formed by nanomagnets with sub-100 nm lateral...
