Kinetics of Hydrogen Abstraction in Alkanes by Mu Reactivity studied by RF Re...
Hydrogen abstraction reactions are key steps in free radical mechanisms that dominate the combustion and atmospheric chemistry of the alkane hydrocarbons and, as such, merit... -
Muon Spectroscopy and Artificial Hydrogenases (RB920382)
The reversible interconversion of protons and dihydrogen is an electrochemical process of fundamental importance to a hydrogen economy. The process requires catalysis to proceed... -
Muon level-crossing resonances as a probe for studying antiferromagnets at pu...
We propose a set of measurements using the HiFi spectrometer in which muon level-crossing resonances are used to probe the internal field inside antiferromagnets in which the... -
Towards a Method of Quantifying Electrophilicity and Nucleophilicity
Understanding of chemical reactivity is founded on the fundamental concepts of Electrophilicity and Neucleophilicity. All extant attempts to do this depend on the reaction of... -
Probing the [FeFe]-hydrogenase subsite using muon spectroscopy
Solid state repolarisation measurements of [Fe2(µ-pdt)(CO)4(PMe3)2] (RB 1010177) showed a weak recovery at ca.15G, a strong recovery at ca.100G and what was thought to be a weak... -
Low field µSR studies of radiation chemistry and free radical reactions by no...
Microwave (MW) assisted chemical reactions are of interest as a green, energy efficient alternative to conventional thermal heating for chemical processes. MW irradiation... -
Muonium and Flourine Entangled States In An Organic Based Spin Peierls System
Potassium TCNQ is an stoichiometric organic based salt that undergoes a spin Peierls (SP) transition at approximately 390 K. Much research has been conducted on this system in... -
Development of Radio Frequency µSR as a Method for Determining Hyperfine Coup...
Radio Frequency µSR provides a direct method for accurately determining muon hyperfine coupling constants, Aµ, for muoniated radical species. The method complements the well... -
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... -
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... -
Utilising Quadrupolar Level Crossing Resonance to Gain Important Information ...
There is much debate about muon stopping sites within materials and in many cases knowing where the muon stops is crucial to understanding the physical properties of different... -
Identifying the mechanism behind spin relaxation in organic materials
We wish to measure the low-field ALCs of a series of related functionalised acenes to identify which mechanism (spin orbit or hyperfine) is responsible for spin relaxation in... -
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... -
Multiferroicity in metal-formate perovskites
Recent work has revealed that metal-organic frameworks (MOFs) can also exhibit this multiferroicity. These materials are particularly interesting since their structures are... -
Understanding Spin Density Variations in Fluorinated TCNQ Adducts
There is a large emphisis on fucntialising materials to create magnetic and electrical materials. Tetracyanoquinodimethane is a famous material discovered in the 1960 and ws... -
Repolarization of Radicals in Liquids (RB920344)
The recovery of the muon polarization in a longitudinal magnetic field has been used to obtain the muon hfcs of organic radicals. In pure benzene there is a single step in the... -
