Cyclic peptides with alternating side chain stereochemistry are capable of self-assembling into long nanotubes. The conjugation of polymers to these peptides renders the...

In the proposed experiments we extend previous work on characterization of aggregates formed by cationic conjugated polymers and oligomers in water. Particular emphasis will be...

The increasing incidence of pathogenic fungi resistant to treatment with amphotericin B (AmB) has created a demand for novel anti-fungal agents that can circumvent the...

Cyclic peptide-polymer conjugates can readily self-assembly into long nanotubes, and are being extensively studied for drug delivery applications. Recently, using SANS and...

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....

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...

A number of important biological processes, such as intracellular transport and signal transduction depend on the viscosity and the distribution of microdomains in cells. We...

The aim of the project is to use Small Angle Neutron Scattering (SANS) to determine the particle sizes and the internal shell dimensions of the nanogels as a function of the...

The aim is to measure any tendency towards phase separation in a nematic mixture to complement an adsorption study on the same mixture. The base is 4-pentyl 4¿- cyanobiphenyl...

We request SANS beam time on LOQ to study the impact of multivalent counterions on the micellisation of alkyloxyethylene sulfate surfactants and alkyloxyethylene sulphate /...

Peptide-functionalized nanoparticle (NP) aggregates have significant potential as biosensors (for specific enzymes) due to their high sensitivity, modular design and simple...

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...

The aim of this experiment is to investigate surfactant aggregation in ionic liquids and also ionic liquid ¿ oil and ionic liquid ¿ water microemulsions via SANS. Contrast...

A series of well defined comb polymers consisting of methacrylate backbones and oligo(2-ethyl-2-oxazoline) side chains was shown to exhibit lower critical solution temperature...

Using LOQ, we have recently shown that self-assembly of fluoro-sulfocuccinate surfactants is indeed a viable approach to promote viscosity enhancement in liquid CO21 (Rod-like...

The proposal aims to explore water-in-CO2 (w/c) microemulsions with new, very promising hydrocarbon surfactants. The compounds are generated using standard chemistry1 but with...

The life-limiting feature of AGR power reactors is probably radiation damage to the graphite moderators. This proposal (part of a collaborative EPSRC programme - Fundamentals of...

The aim of this experiment is to characterise several novel ionic liquid ¿ oil and ionic liquid ¿ water microemulsions via SANS prior to their use in the synthesis of metallic...
