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...

Dipeptide-based gelators can form hydrogels at low concentrations using a number of means. We have found that the method by which the gels are formed can have a profound effect...

Reheat cracking is a creep failure mode that has been observed in welded structures operating at high temperatures in the power generation industry. The failure results from the...

Carboxymethylcellulose (NaCMC) is the most widely used cellulose derivative; it forms an anionic, water-soluble, polyelectrolyte with vast applications in the food,...

This proposal aims to explore cheap and environmental-benign cosurfactants (or cosolvents) for yielding CO2-philic hydrocarbon surfactant/water/CO2 microemulsions (W/CO2...

Solventless protein liquids (SPLS) represent a novel form of biological matter. Recently we reported on the preparation and properties of a solvent-free liquid protein based on...

The aim of the experiment is to monitor the temporal evolution of gamma prime precipitates in three polycrystalline nickel base superalloys using Sans2D. This instrument is...

Small angle neutron scattering will be used in combination with contrast variation as a non-invasive method to detect the presence and size formation of lipid microdomains or...

We have been developing hydroxypropylmethyl cellulose (HPMC) microspheres for delivering poorly water-soluble drugs. The in vitro dissolution data showed that the presence of...

We propose to use the new SANS2d to study the dynamic structural evolution in the couse of the formation of DNA-cationic polymer complexes. The dynamic process and the mixing...

Recent experiments on SANS2D have indicated that small colloidal particles can act as macroions that screen the charged interactions of larger particles. This can cause changes...

Complexes prepared from cationic, dichain lipid (L) vesicles, positively chargely targeting peptides (P) and negatively charged DNA (D) or siRNA (R), known as LPDs and LPRs...

This proposal aims to explore these dispersed lamellar phases with a variety of F7H4 derivatives,to help understand their formation in supercritical CO2 (sc-CO2). The focus is...

In the present proposal small angle neutron scattering will be used in combination with contrast variation as a non-invasive method to detect the presence and size formation of...

In recent dielectric and calorimetric studies of some alcohol-water mixtures we have discovered unexpected and unexplained relaxation behaviours. Our aim with this proposal is...

This proposal is part of a new project based on understanding the formation of gels in suspensions of partially oxidised cellulose nanofibrils with small amounts of salt or...

Gram negative bacteria cause a wide range of diseases including meningitis, bubonic plague, gonorrhoea, diarrhoea, Legionnaires' disease and cholera. Their outer membrane...

The aim of the proposal is to improve understanding about combinations of normal surfactants and hydrotropes. The systems of study are reference oil-water interfaces, provided...

Large multiprotein complexes are the new frontier in structural biology. Individual proteins may be solved by X-ray crystallography but the relationships between subunits and...

Plasmonic nanoparticles (NPs) are emerging as a promising category of materials, which might find applications in optical storage of information, optical wave guiding,...
