The development of new nanomaterials for agricultural and environmental applications is a topical field. To control loading of the bioactive agents and their subsequent release,...

We request one day’s beam time on SANS2D for the study of hydrated, radiation-grafted anion-exchange membranes synthesised with different grafting times. These materials are...

N-acyl amino acids are surfactants with attractive applications in different technological fields. They are referred to as mild surfactants because they are commonly considered...

We have been focusing on two component gel networks. Here, both components can individually form gels. In a mixed system, the LMWG can either co-assemble or self-sort. In a...

Please ignore. This is just for setting up ERAs ready for the Neutron Training Course.

We intend to use small angle neutron scattering to investigate the conformational behaviour of a range of amphiphilic copolymers comprising a hydrophobic methacrylate segment...

The aim of our work is to study structural properties of supra-molecular assemblies formed in aqueous solutions of cationic pH- and thermo-sensitive block-gradient copolymers...

Our group has been working cellulose nanofibrils (OCNF) which form hydrogels in the presence of certain additives. Previously, we have studied the effect of salt, single...

Addition of multivalent salts to water soluble polyelectrolytes, such as sodium carboxymethyl cellulose (NaCMC), induces conformational change to the polyelectrolyte structure,...

The current project aims to probe (at the nanometer length scale) the relationship between the structure of a surfactant molecule, the micelles it forms in solution, and the...

Incorporation of d- or f-block metals into ligand systems that renders a metal complex surface active or drives its partitioning into surfactant phases enables the localisation...

Polyurethane foams (PUF) are commonly prepared by mixing Pluronic type copolymers and isocyanate reactive monomers in the presence of additives e.g. catalysts, blowing agents...

The MES is representative of a promising group of anionic surfactants which have the potential for improved performance and biocompatibility / biosustainability, and their...

This proposal builds upon the successful study of a cationic copolymer capable of forming polymer micellar-like aggregates, simply by reducing pH (D33 at ILL 9-12-433 see...

Building from work previously carried out at ISIS (RB1410544) and pulished open-access in Chem. Commun. 2016, 25, 7344, we propose a SANS experiment to investigate the structure...

Low molecular weight gelators (LMWG) form hydrogels via self-assembly in water under specific conditions to form long, fibrillar structures. Non-covalent forces interactions...

We have been studying the solution interactions leading to formation of solid polymer-surfactant films at the air-solution interface. We want to use the mesostructures in the...

Very recently (April) we undertook a SANS experiment (RB1110147) to probe the partitioning of metal-acac ligand complexes in complex microemulsion media. Our aim was to design a...

The aim of this experiment is to investigate the change in conformation of a chiral polymer dissolved in hexafluoroisopropanol as the temperature of the system is varied....

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...
