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...

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...

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

The MuSES project currently ongoing in the HiFi spectrometer gives unique opportunity in the field of photochemistry and photophysics of organic molecules. After two successful...

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...

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...

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...

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...

This experiment proposes the continuation of a study, initiated at J-PARC, on a new type of activated carbon material, with a pore structure and chemistry "tunable" in a manner...

Metallic systems with one-dimensional chain-like atomic structure can support unusual mechanisms for electron pairing leading to superconductivity. K_2Cr_3As_3 is one of a...

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...

Recent muon level-crossing measurements in the stable orthorhombic alpha-phase of sulphur indicate the existence of a radical state, with an interesting temperature evolution....

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...

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...

Antioxidants are very important molecules because they can prevent or slow down the oxidative damage to our bodies. When our bodies use oxygen, free radicals are released which...

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...
