In the previous proposal we examined the ALC response of components of the complex dielectric under externally applied electric fields (EEF). We saw a shift in the asymmetry at...

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...

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)...

A 19-electron organometallic radical was produced by the reaction of muonium with ferrocene and characterized by avoided level crossing muon spin resonance (ALC-muSR) and...

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...

We plan to measure the electric field distribution in epoxy resin based dielectrics close to breakdown using muons to detect the free charge carriers that may contribute to...

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...

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 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...

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...

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...

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...

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...

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...

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...

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...

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 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...
