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... -
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... -
Muon Spin Relaxation and ALC Resonance in Magnetic and non-Magnetic Oxalate S...
Repolarisation and level crossing resonance will be studied for several different oxalate compounds where muon radical states are known to be formed. Such compounds form a... -
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¿... -
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... -
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... -
A GENERAL METHOD OF MEASURING ANTIOXIDANT CAPACITY
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... -
Detailed temperature dependence of the low-field ALC in TMS-Pentacene
We wish to investigate the evolution of the low-field ALC peaks with temperature of TMS-Pentacene, so we can extract the temperature dependent electron spin relaxation rate. Our... -
Novel Anti-Oxidant Mechanisms 3: Extending the Gamut to Lycopene, THC and Mel...
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...
