Commissioning Proposal ¿ Gas Cell Development
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... -
Muon Level Crossing Resonance Studies of Anion-exchange Membranes Under Diffe...
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... -
Models of the [FeFe]-hydrogenase active site: high symmetry in a biologically...
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... -
Dynamics in oleic acid: solid and melt.
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... -
Anomalous temperature dependence of the ALC spectrum of polybutadiene
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... -
Interaction of N2O with Membranes Using µSR
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... -
Quantum tunnelling of muonium via radical states in molecular solids
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... -
Organometallic Radicals
Avoided level crossing muon spin resonance (ALC-muSR) is an exceptional tool for determining the structure and probing the dynamics of radicals but there have been only a few... -
Muon response to changes in the charge distribution of the components of a co...
We plan to confirm that the change in asymmetry on resonance in the ALC spectra seen in the subject complex dielectric during the previous rapid access proposal (RB1900028) is a... -
Models of the [FeFe]-hydrogenase active site: raising the symmetry
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... -

Capture and isolation of radicals by green tea antioxidants
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.... -
ALC muon spectroscopy of antioxidants
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... -
Artificial [FeFe]-Hydrogenases and Muon Spectroscopy
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... -
Green vs Black Tea Anti-oxidant Potency as a Function of Fermentation Complet...
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¿... -
Electron Spin Relaxation Studies In the 5,7-Br/Cl/I Substituted Aluminium- Hy...
We have recently performed high field ALC measurements on the polycrystalline Metal Tris(Hydroxy-quinolate), MQ3, series in order to further investigate the intrinsic electron... -
characterisation of muonium in functionalized acenes
We wish to measure the high field ALCs of a series of related functionalised acenes, to understand the role of the ligands on the electron spin relaxation, which is of... -
ALC spectroscopy of the molecule BEDT-TTF and some of its salts
The electron donor molecule BEDT-TTF (ET) provides a versatile building block for constructing molecular metals, superconductors, magnets and quantum spin liquids. A common... -
Probing the [FeFe]-hydrogenase subsite using muon spectroscopy
Previous ALC measurements of the Fe2(pdt)(CO)4(PMe3)2 and [Fe2(pdt)(CO)4(CN)2]2- (referred to as 1 and 2) model hydrogenase subsites have yielded some intriguing results (RB... -
Silicon nanoparticles in thermoelectric material applications - Solution stat...
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...
