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...

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...

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 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...

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...

Molecular modelling suggests that the antioxidant molecule EGCG "folds up" around the radical it captures, and therefore should shield the spin density from the environment....

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...

Since ancient times it has been known that using boiling water to prepare tea ¿burns¿ the brew destroying the teas flavours & beneficial nutrients. One aspect of a ¿burnt¿...

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...

During our previous experiment on HiFi (RB1320541) we measured the ALC spectrum of the Fe2(µ-pdt)(CO)4(PMe3)2 model hydrogenase complex over multiple temperatures. The spectra...
