Electron transfer (ET) processes in peptides and proteins are key steps in the functioning of several natural enzymes including DNA photolyase and ribonucleitide reductase,...

Copper (I) hydride, CuH, is unique amongst the binary metal hydrides in that it can be synthesised, at room temperature, in aqueous solution. In recent years CuH generated in...

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...

Demand for new medical & biomaterials with elevated longevities is accelerating through the ageing of the population. The historic implantation of foreign materials into the...

We propose to investigate the vibrational dynamics of N-heterocyclic carbenes (NHC) on TOSCA.The here proposed study complements theoretical works in hand for these novel...

To the best of our knowledge, there is no previous work on using muons to measure photo-excited states in organic semiconductors or related materials. Our photo-excitation ideas...

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¿...

Our recent theoretical and experimental characterisations of novel Pd N-heterocyclic carbene catalysts showed a clear relation between low-energy normal mode energies and...

In this proposal we would like to study the structure of polar aprotic and aromatic liquids using H/D and 15N/*N isotopic labelling on SANDALS. The molecules chosen for study...

The present proposal is part of a project to formulate a quantitative synergy between experiment and theory, complimenting the results the applicants have already established in...

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....

A proposal is made to measure atom/ion mobility/diffusion in GIC samples. Vesuvio is ideal to explore diffusion of ions bound by ~0.5-5eV bond energies and covalently bound...

In recent years, soluble derivatives of CuH prepared by non-aqueous routes have become important as mild reducing agents, one such compound, Stryker¿s reagent [Ph3PCuI]6. The...

Our recent theoretical and experimental characterisations of novel Pd N-heterocyclic carbene catalysts showed a clear relation between low-energy normal mode energies and...

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...

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...

CuH was first prepared by Wurtz in 1844 by the reaction of aqueous copper sulfate with hypophosphorous acid. Several other routes have been developed including precipitation of...

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...

Our recent works have solved a 50 yr old problem (in part) with computational steering successfully guiding synthetic work towards a wittig process catalytic in phosphine. The...

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...
