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¿... -
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... -
Probing the [FeFe]-hydrogenase using muon spectroscopy
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... -
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... -
Rates of Molecular Transfer Across Interfacial Layers Using µSR
The first direct measurements of the rate of transfer of a probe molecule across an interfacial layer have been made at PSI, using TF and ALC-MuSR. This application for beamtime... -
ALCs investigation of the polymer PTAA (chain length = 80)
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...
