Proposal to determine the origin of the effects of electric fields on the muo...
In the previous proposal we examined the ALC response of components of the complex dielectric under externally applied electric fields (EEF). We saw a shift in the asymmetry at... -
Silicon nanoparticles in thermoelectric material applications
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... -
DYNAMICS OF SURFACTANTS IN LUBRICATING OILS
In a recent series of successful experiments at PSI and ISIS we were able to demonstrate the possibility of measuring the rate of transfer of a small molecule (allyl alcohol)... -
Organometallic Radicals
A 19-electron organometallic radical was produced by the reaction of muonium with ferrocene and characterized by avoided level crossing muon spin resonance (ALC-muSR) 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... -
Novel Mechanisms of Green Tea Anti-Oxidants by Mu-SR, INS and DFT Experiments
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... -
Muon charactersiation of dielectric insulation system under applied electric ...
We plan to measure the electric field distribution in epoxy resin based dielectrics close to breakdown using muons to detect the free charge carriers that may contribute to... -
Field-induced Tomonaga-Luttinger Liquid phase in a spin ladder
The new molecular magnet bis(2,3-dimethylpyridinium) tetrabromocuprate (DIMPY) is a strong-leg spin ladder with a quantum critical point at 3 T separating a low-field... -
The electronic structure and magnetic properties of metal nanoparticles stabi...
In recent years, nanoparticles have been a major source of interest in a wide range of fields. Our long term objectives are tuning the free radical reactivity on the surface of... -
Identification and dynamics of muon states in octabutoxy-phthalocyanine
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... -
RF μSR in the gas phase: understanding a ¿null¿ result
We have made a significant effort to develop Radio Frequency μSR (RF μSR) as a technique for spectroscopy of organic radicals in the gas phase. Realising this method... -
The role of spin-orbit interaction on Group-III-trisquinolates
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... -
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... -
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... -
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... -
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... -
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... -
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...
