Interaction of Xe with Membranes Using µSR
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... -
Effect of electric field on paramagnetic state formation in molecular semicon...
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... -
ALC studies of solid benzene
For muoniated radical spectroscopy studies, benzene has long been the classic prototype system. However most of these studies have been at higher temperatures, often in the... -
The effect of metal nanoparticles on the electronic structure of bound free r...
In recent years, the noble metals nanoparticles (MNPs) have been the subject of intense interest in areas of materials science, biotechnology, medicine and organic chemistry for... -
Towards a validated standard method for performing DFT calculations of muoniu...
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... -
Level crossings in open ring molecular magnets
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... -
End-Game: Cornering Solvent Effects on H-Addition in Green Tea Anti-Oxidants
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... -
Level crossings in the open ring molecular magnet Cr8Cd
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... -
Characterisation of Green-Tea Radical Scavengers by ALC-MuSR and High-Level C...
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... -
Separating static and dynamic contributions to the muon relaxation in Ca3(Co,...
Ca3CoMnO6 has alternating ions in ferromagnetic Ising chains that are antiferromagnetically coupled on a triangular lattice and realizes an important model in frustrated... -
Study of the dependence of electron spin relaxation on molecule length in acenes
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... -
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... -
Electron Spin Relaxation Measurements of P3OT
Using muon spin relaxation and ALC resonance spectroscopy, the electron spin relaxation and mobility of the polymer P3OT will be determined. P3OT differs in structure to P3HT... -
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... -
A search for the muoniated hydroxyl radical, OMu
The elusive OMu radical is believed to be formed by muonium reaction with nitrous oxide but has never been directly observed. It would be invisible to transverse-field muon spin... -
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...
