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...

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...

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...

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

Topological materials hold promise in quantum information processing as a fault tolerant basis for operations and manipulations of quasiparticles that exist at the material...

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...

Porous polymer materials are important given their use in a wide variety of applications, for example detection of pollutants in the environment or security sensing of explosive...

This proposal continues our studies of water and small molecule binding around surfactant micelles using NIMROD, to obtain previously inaccessible details of their molecular...

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...

Materials that are porous at the atomic scale have proven to be important for many applications, including gas capture and catalysis. Recently it has become possible to make...

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

Organic photovoltaics (OPVs) are a class of solar cells that harvest photogenerated excitations ('excitons') and split them into free charges to generate electrical power. A...

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...

Low temperature embrittlement of stainless steels are due to phase separation and it is known that the kinetics of phase separation depend on the initial structure. However, the...

The family of guanidinium metal formates has the perovskite structure and, like many perovskites, is of interest for these materials¿ magnetic and electric properties, in...

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...

We propose muSR studies on superfluid density in the overdoped La2-xSrxCuO4 (LSCO). The Hayden group (Bristol) has been growing high-quality LSCO single crystals, and performed...
