Spontaneous surface multilayer formation in oligoamine ¿ surfactant mixtures
This proposal is part of a major EPSRC (EP/GR065705)/Unilever funded programme to develop and control the spontaneous formation of surfactant multilayer structures at... -
Zwitterion doped PEDOT:PSS bulk morphology modification as a function of dopi...
We propose to use SANS to study the intra-particle information (size, shape, interactions) of pristine and zwitterion doped PEDOT:PSS in order to have a better understanding of... -
A Time-Resolved SANS Study of the Gelation Mechanisms of Tetrapeptide Hydroge...
Time-resolved SANS will be used to investigate the mechanisms and kinetics of ordering of aseries of novel designed tetrapeptide-based hydrogelators. These inexpensive materials... -
Ionic Liquid ¿ Water Interactions
This project aims to examine the structure of microemulsions formed by water and 1-methyl-3-ethylimidazolium-based ionic liquids with the acetate or octanoate anion. These... -
Determining the Order in Aqueous Solutions of Pharmaceuticals
We request 6 days on NIMROD to collect total scattering neutron diffraction data of aqueous solutions of paracetamol and caffeine. While much effort has gone into improving the... -
Exchange kinetics of complex coacervates core micelles
Coacervates have been studied for a long time for their unusual properties: they are dense networks of charged polymers that are soluble in water. Instead of flocculating when... -
Proton Zero Point Energy Effects on the Folding of Proteins
Earlier experiment at ISIS have shown that water responds to the distortion of the hydrogen bond network by delocalizing some of the protons in the vicinity of the defects. That... -
D2O Vapour Diffusion at the Air Water Interface
A theoretical estimate of the H/D exchange rate for an open trough (e.g. D2O in ambient atmosphere, 50% relative humidity) yields an amount of exchanged liquid of the order of... -
A SANS Study of Hydration Shell and Magnetic Field Alignment of Amyloid Pepti...
We will perform neutron scattering experiments (SANS) to probe the mechanism of alignment of amyloid peptides on drying in the presence of a 2T magnetic field, as well as the... -
Polystyrene latex - 'single crystal' structure studies and melting under flow
For deionised, charge stabilised latices, there has been some uncertainty about the stacking sequence of close packed layers in samples at equilibrium. The ABCA stacking in... -
Adsorption of proteins from Moringa seeds at the air/solution interface
Proteins from Moringa trees have attracted considerable interest as flocculents for water purification and possibly as materials for remediation of contaminated soil.... -
Interactions of modified clupeines with Gram-negative model bilayers
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... -
Binary colloidal mixtures - SANS contrast variation to study high concentrati...
Mixtures of colloidal particles of essentially two different sizes are commonly used in technological applications such as film formation on surfaces, paper coatings, etc.... -
SANS Contrast Matching Studies of Radiation-grafted Anion-exchange Membranes
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... -
Protein density profile near protein-resistant self-assembled monolayers: Sen...
Oligo(ethylene glycol) self-assembled monolayers (SAMs) effectively prevent the adsorption of proteins from biological media. Despite the importance of this effect for... -
Micellization in glycerol:choline chloride deep eutectic solvent
Deep Eutectic Solvents (DES) are molecular mixtures with melting points below room temperature. DES share many features of ionic liquids (low vapour pressure, adjustable... -
Interfacial Structure of Colloidal Dispersions - the air/latex interface
Adsorption of colloidal particles to an interface is of fundamental interest in understanding wetting, capillarity and colloidal forces as well as being of practical importance... -
Exchange kinetics of complex coacervates core micelles
Coacervates have been studied for a long time for their unusual properties: they are dense networks of charged polymers that are soluble in water. Instead of flocculating when... -
The competition between two polymers for adsorption onto one surface
The behaviour of multiple polymers in competition for colloidal silica has previously been investigated in our group using solvent relaxation nuclear magnetic resonance. We... -
SANS Contrast Matching Studies of Radiation-grafted Anion-exchange Membranes
