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...

Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Recent µSR studies of bare Au NPs encapsulated in mesoporous...

The first direct measurements of the rate of transfer of a probe molecule across an interfacial layer have been made at PSI, using TF and ALC-MuSR. This application for beamtime...

We propose to determine the possibility for H-addition occurring in the natural anti-oxidants lycopene, melatonin and Delta9-THC, by ALC-muSR on the HiFi instrument. Our...

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...

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¿...

Using muon spin relaxation and ALC resonance spectroscopy the electron spin relaxation and mobility of the polymer P3HS will be measured as a function of temperature. The...

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...

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...

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 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...

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

We propose to characterize the two magnetic transitions in Nd0.75Gd0.25Rh3B2 and study the spin dynamics and field induced domain rotation via zero field (ZF) and longitudinal...
