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)...

U2Pt2Sn crystallizes in the tetragonal Zr3Al2-type structure (P42/mnm, Z = 4), where uranium atoms occupy two different sites. Our measurements of bulk properties have shown...

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 kappa structural phase of BEDT-TTF salts incorporating various anions X provides an extremely interesting series of layered-structure strongly-correlated materials, whose...

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...

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...

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

Following our investigation of alpha-orthorhombic sulphur, we will measure level crossing spectra of some other allotropes and phases, to find if the muon radical observed in...

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...

This proposal looks to study the electron spin relaxation using high field ALC measurements in two polymers, which differ only by the non-metal (i.e S or Se) in the polymer...

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...

Molecular nanomagnets (MNMs) comprise clusters of exchange coupled transition metal ions which often have a negative anisotropy constant, favoring a ground state with a large...

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...

Ca3CoMnO6 has alternating ions in ferromagnetic Ising chains that are antiferromagnetically coupled on a triangular lattice and realizes an important model in frustrated...
