In a recent series of successful experiments at PSI and ISIS we were able to demonstrate the possibility of measuring the rate of transfer of a small molecule (allyl alcohol)...

The extreme quantum nature of muons and muonium in condensed matter is the result of having a mass that is nine times lighter than that of a hydrogen atom. While this quantum...

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...

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 recent years, the noble metals nanoparticles (MNPs) have been the subject of intense interest in areas of materials science, biotechnology, medicine and organic chemistry for...

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...

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...

Following recent experiments in which the shallow donor muon states in semiconductors are found to have significant electron polarisation at low temperatures and high fields, we...

An important element of the work associated with the current Framework Programme 7 Joint Research Activity (JRA) for muons is the development of gas sample pressure cells...

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...
