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...

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...

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...

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

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 measure electron-hole recombination rate in low-temperature pure silicon using the photo-MuSR technique. The previous works have measured the recombination rate down to -30...

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...

Spin ladders represent a class of low-dimensional quantum magnets that occupy a regime of subtle behaviour which lies between the stark extremes of the one-dimensional chain or...

Gadolinium gallium garnet (GGG) is a frustrated system which has already been successfully studied using muons. This study extends the earlier work to high magnetic field and...

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

We wish to measure the low-field ALCs of a series of related functionalised acenes to identify which mechanism (spin orbit or hyperfine) is responsible for spin relaxation in...

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...

Previous work on the polymer RR-P3HT has found that the ALC resonance collapses at 100K to ~80% of the 300K ALC magnitude, this is much larger than the decrease seen for small...

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...

Dy2Ti2O7 is a pyrochlore antiferromagnet that has a partial magnetization plateau between 0.1 and 0.9T for magnetic fields applied along the [111] direction. This represents a...

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...
