The aim of the present study is to use neutron diffraction enhanced with isotopic substitution and subsequent computer simulations to determine the head group solvation of a...

We have recently prepared a number of new nucleobase functionalised polymers which undergo interesting and unexpected self-assembly. We hope to use SANS to explore further the...

The proposed work continues our investigations of the structure, aggregation, self-assembly and ion pairing of ionic liquids in the neat state, at interfaces, and in solutions....

The elucidation of the compositional profile inside the polymer nanoparticles is of critical importance for applications such as water processable organic solar cells. In order...

The aggregation of the Amyloid beta (Abeta) peptide is implicated in the progression of Alzheimer's disease, the treatment of which is a major current global healthcare...

Off-specular neutron reflection beamtime is requested to study phase separation at the air/water interface. Stability of systems, such as polymers, is a major area of interest...

Stabilizers of colloidal particles are often complex and their function may involve several mechanisms to impart stability of a wide range of conditions. Sodium polyacrylate is...

Liquid crystalline particles consisting of glycerol dioleate (GDO) / soy phosphatidylcholine (SPC) mixture and stabilised by polysorbate 80 (P80) have proven to be suitable as...

Organic photovoltaic (OPV) cells have the potential to be the basis of a renewable energy source that is inexpensive and portable. Current state-of-the-art solution-processed...

Hydroxyethyl cellulose (HEC) is commonly used as a viscosity modifier in many chemical systems, from paints to cement. HEC forms a physical gel in water due to the presence of...

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...

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 behaviour of multiple polymers in competition for colloidal silica has previously been investigated in our group using solvent relaxation nuclear magnetic resonance. We...

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...

Deep Eutectic Solvents (DES) are molecular mixtures with melting points below room temperature. DES share many features of ionic liquids (low vapour pressure, adjustable...

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

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...

Mixtures of colloidal particles of essentially two different sizes are commonly used in technological applications such as film formation on surfaces, paper coatings, etc....

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...

Proteins from Moringa trees have attracted considerable interest as flocculents for water purification and possibly as materials for remediation of contaminated soil....
