We want to measure the SESANS from a series of large ~1 micron silica particles formed using the multistage Stöber method. The reason for this is to determine if we can see the...

In polymer-fullerene based photovoltaic systems the phase behaviour of the blends is poorly understood and remains a fundamental stumbling block to improvements in device...

Antibiotic resistance is pathogenic bacteria is a major clinical problem. Resistance to all antibiotiotic classes, currentl yin clinical use, has been reported. By contrast, the...

Dynamics of multicomponent mixtures such as polymer blends are typically studied with QENS and deuterium labelling. Difficulties arise in the data analysis if the coherent...

Blends of fullerenes with conjugated polymers (CP), such as PCBM-P3HT blends, are being extensively investigated for polymer photovoltaic applications. We have been studying the...
