Titanium dioxide (TiO2) is used in a wide range of applications from medical and dental implants to treatment of contaminated air and water streams. However many of the...

Objectives of this proposal aim to shed light on how adsorption processes such as protein A chromatography, used to purify biologics, affect protein propensity for aggregation....

We propose to investigate in-vivo cell membrane structure of gram-positive (B. subtilis) and gram-negative (S. oneidensis) bacteria adhered to a silicon oxide surface using...

Purothionins and defensins are basic, amphiphilic, cysteine-rich and low molecular weight plant defence proteins. These proteins are active against a broad range of...

Today, a number of technological devices, such as the readout sensor in the hard disc drive, have used the exchange bias (EB) effect, which arises in a...

In this proposal, we request beamtime to study the unexpected behaviour of a strongly bound bilayer of the cationic surfactant didodecyldimethylammonium bromide on the anionic...

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...

Many relevant hints on the superconducting properties of a family compound can be derived from the behavior of the temperature and/or doping dependence of the superfluid...

In the field of semiconductor spintronics, n-type GaAs has been utilized as a prototype system, where one can inject electronic spin and study its behavior with optical...

Antibody-antigen binding has been extensively used in many technological applications such as immunoassays, chemical analysis and bionanotechnology. The crucial element...

DNA is a versatile building material for nanotechnology. We have recently studied a surface-tethered single-domain DNA motor by neutron reflection (IR) for the first time. We...

In a recent EPSRC / Unilever / Oxford CASE project we have used NR to explore and develop optimised delivery mechanism for active benefit agents such as perfumes. In particular...

Pore forming lipopeptides, such as Tolaasin, are produced by pathogenic mushroom bacteria, and are implicated in diseases such as ¿brown blotch¿ disease. They have potential...

The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly has until recently been rarely observed. However, surface multilayer structures...

Calcium ions have been shown in a preliminary experiment to have a dramatic effect on the thickness and structure of free supported bilayer films. In this proposal we...

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...

N-salicylidineanilines are known to show thermochromic behaviour, which is currently postulated to arise from an intramolecular proton shift between the keto and enol form as...

The crystallisation of membrane proteins is of great interest, not least, to the pharmaceutical industry. We have recently begun a project aiming to investigate the role played...

Purothionins and defensins are basic, amphiphilic, cysteine-rich and low molecular weight plant defence proteins. These proteins are active against a broad range of...

Neutron reflectometery will be used to provide the vital information about the interaction/conformation of the organophosphonate compound on the lipid structure in the...
