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)... -
Spin Rotation Experiments at a Pulsed Muon Source using Broadband RF Pulses
In this proposal we wish to explore how the RF-uSR technique might be developed for measurements akin to FT-NMR. Our work will focus on the broadband excitation of paramagnetic... -
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... -
Copy of: Towards a Method of Quantifying Electrophilicity and Nucleophilicity
Our understanding of chemical reactivity is founded on the fundamental concepts of Electrophilicity and Neucleophilicity. There are a number of attempts of limited applicability... -
Muon radicals in the metastable phases of Sulphur
Following our investigation of alpha-orthorhombic sulphur, we will measure level crossing spectra of some other allotropes and phases, to find if the muon radical observed in... -
Muonium in alpha-boron
Previous muon experiments have identified a muonium state in the commonly occuring, but complex, beta rhombohedral form of elemental boron. To complement recent theoretical work... -
A METHOD OF MEASURING ANTIOXIDANT CAPACITY
Antioxidants are receiving increased attention for their potential effects in the prevention of chronic and degenerative diseases such as cancer and cardiovascular disease as... -
Investigating regiochemistry of artificial [FeFe]-hydrogenase subsites using ...
During our recent experiment (RB1310434) we were able to use ALC to characterise the radical states formed in [Fe2(µ-pdt)(CO)4(PMe3)2] and [Fe2(µ-pdt)(CO)4(CN)2]2- at two... -
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 carrier-induced donor-to-acceptor transition of muonium in indium...
The first experiment we propose is a search for a shallow-donor signal for muonium in indium oxide. Its observation would test our assertion, based on our measurements of... -
Muon states in black phosphorus
Our recent experiment showed that muons implanted into black phosphorus (the most stable allotrope of the element, with a low band gap of 0.3eV) are apparently diamagnetic, with... -
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... -
Investigating the muon radical in Sulphur
Recent muon level-crossing measurements in the stable orthorhombic alpha-phase of sulphur indicate the existence of a radical state, with an interesting temperature evolution.... -
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... -
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... -
A Unique Method of Measuring Antioxidant Capacity
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... -
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... -
