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 relative importance of factors affecting the low temperature ALC spectra of organic molecular systems such as polymers and small molecules is a topical issue. Polybutadiene...

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...

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...

Anion-exchange membranes are used in alkaline fuel cells, a technology which allows for the production of power from hydrogen in impure gas streams. Very little is known about...

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...

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...

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...

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...

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...

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...

For muoniated radical spectroscopy studies, benzene has long been the classic prototype system. However most of these studies have been at higher temperatures, often in the...

The effect of electric field on the diamagnetic and paramagetic muon spin rotation signals will be investigated for the organic molecular semiconductors NPB and TPBi . These...

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...

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...

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 current experiment proposes to identify and study the spin dynamics of the muon states formed in octabutoxy-phthalocyanine (oBu-H2Pc) using the avoided level crossing...

Benzophenone is an ideal material to study vibrations of a muon radical centre with near-IR laser light, as all C=O bonds in solid state are almost parallel to each other and 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 new molecular magnet bis(2,3-dimethylpyridinium) tetrabromocuprate (DIMPY) is a strong-leg spin ladder with a quantum critical point at 3 T separating a low-field...
