A proposal is made to continue ongoing ALC-muSR experiments on the green-tea anti-oxidant EGCG and its analogue. Several overlapping resonances observed on HiFi made it...

In recent years, nanoparticles have been a major source of interest in a wide range of fields. Our long term objectives are tuning the free radical reactivity on the surface of...

We have made a significant effort to develop Radio Frequency μSR (RF μSR) as a technique for spectroscopy of organic radicals in the gas phase. Realising this method...

The great majority of known muonium defect centres and muonium substituted organic radicals have essentially spin-only magnetism, with few exhibiting any noticeable departure...

Spin based electronics (spintronics) is one of the most exciting and challenging areas in nanotechnology. It is expected to be of major scientific and social impact. Very little...

The mechanism of action of inhalation anaesthetics such as N2O and the inert gases are unclear. Direct binding to receptor sites on membranes would rely on weak intermolecular...

In this proposal we want to address the issue of the identification of the different muonium adducts that are possible in Alq3 without any crystallographic constraints, and...

Our ongoing project to characterise radical scavenging by the green tea anti-oxidant EGCG and its D-ring analogue, (3,4,5-(OH)3-Bz) is near-complete. ALC-MuSR experiments on the...

We propose to characterise selected radical structures of the green-tea anti-oxidant flavenoid EGCG (& selected analogues), by DFT/post-HF computation and ALC-MuSR, towards...

We wish to measure the ALCs of a series of polyacene molecules made of a different number of rings. We would like to identify the dependence of the electron spin relaxation rate...

Previous work on the polymer RR-P3HT has found that the ALC resonance collapses at 100K to ~80% of the 300K ALC magnitude, this is much larger than the decrease seen for small...

Increasing interest in biofuels has led to a desire to understand the phase characteristics of the compounds present in these fuels and how the dynamics of the fluid might be...

Nitrous oxide, N2O, is an inhalant anaesthetic with a long history of use dating back to 1844. It is most commonly used as a light sedative in dentistry, or in child birth and...

The [FeFe]-hydrogenase enzymes are some of the best catalysts know for generating hydrogen. We have an ongoing programme to understand how their chemistry works, and to...

The main spectroscopic technique for studying radicals in solids and liquids, ESR, cannot usually be used to study radicals of more than 3-5 atoms in the gas phase due to strong...

In a previous experiment (RB910492) we have made preliminary measurements of the rates of addition of muonium to vitamins C and E, as suggested by the ISIS panel. These rates...

Preliminary measurements of [FeFe]-hydrogenase model complexes were made in a previous experiment using EMU (RB 1010177). The results were interpreted in combination with DFT...

In order to meet the UK's commitment to reduce 80% of greenhouse gas emissions by 2050, it is necessary make major advances in efficient, clean and secure energy conversion and...

Antioxidants are very important molecules because they can prevent or slow down the oxidative damage to our bodies. When our bodies use oxygen, free radicals are released which...

This proposal aims to study the avoided level crossing resonances (ALCs) of the amorphous polymer PTAA, with chain length 80. Previous measurements on PTAA have studied a...
