We have recently demonstrated, using neutron reflectivity in combination with other techniques, that in organic photovoltaic devices (OPVs) the additive 1,8-diiodooctane (DIO)...

Nanoemulsions have considerable potential for dermatological drug delivery. Small angle neutron scattering in combination with contrast variation will be used to characterize...

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

Electrical steels are a type of Fe-Si steel used as transformer cores in the energy industry. Due to a welcomed drive for renewable energies, the understanding of soft magnetic...

Cu-Cr-Zr alloys are the material of choice for coolant structures in fusion reactors, where high thermal conductivity and structural strength at 250-300 C are required. These...

Bowel cancer is the fourth most common cancer in the UK with approximately 41,000 individuals in the UK diagnosed annually. Importantly it is estimated that over half of all...

Colloidal dispersions of organic semiconducting nanoparticles (NPs) have shown promise for the generation of active layers in organic solar cells.Composite NPs containing a...

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...

Studies of creep behaviour in structures that operate at elevated temperatures such as nuclear power plants are important for structural integrity assessments. The effect of...

Recent NR results (fig 1) have shown the ability to characterise surface segregation and nanostructuring of surfactants in PVA film. As well as the fundamental scientific...

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...

Nanoscale magnetic skyrmions are swirl-like magnetisation entities that satisfy topological quantisation conditions. They can therefore not be easily unwound into another...

Polymer/fullerene blends represent the most common form of organic solar cell. This proposal forms part of a wider effort in which our motivation is to complement solar cell...

Hydrotropes (Figure 3 A-C) are known viscosifying agents with surfactants in organic solvents1 and interestingly now in supercritical CO2 (scCO2)5. The mechanism is...

The aim of this work is to use small angle neutron scattering (SANS) to probe the vapour sorption of the ionomeric component of novel proton exchange membranes as a function of...

Optimising catalyst lifetime and performance is pivotal to enhancing the sustainability of industrial catalytic processes, allowing greater product yields, at lower...

Dimethacrylate resins are currently used for dental fillings. The polymers are set by free radical polymerisation. At present light curing protocols require 40s exposure at...

Hydrogels are water-rich polymer networks made from natural or synthetic polymers, which are widely used in biomaterials, medicine and antifouling. We have developed PEG-based...

In this work we will investigate how the magnetic properties of nanometer thick iron-oxide films can be manipulated by heating them in air. Our preliminary results indicate that...
