This proposal aims to study the avoided level crossing resonances (ALCs) of the amorphous polymer PTAA, with chain length 80. Previous measurements on PTAA have studied a...

Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Recent µSR studies of bare Au NPs encapsulated in mesoporous...

MV2O6 brannerites have a network structure in which chains of edge-sharing MO6 octahedra result in 1-dimensional magnetic properties. A recent study reported monoclinic CoV2O6...

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...

Our uSR measurements on superconducting Y1-xErxNi2B2C shows a slowing of the Er spin dynamics upon cooling to 2.5 K, but the depolarisation rate does not critically diverge and...

Antioxidants are very important molecules because they can prevent or slow down the oxidative damage to our bodies. When our bodies use oxygen, free radicals are released which...

We plan to measure the hyperfine constants for both the muon and the equivalent hydrogen atom in a small muonated radical using time-differential ALC. We will follow this as a...

During our previous experiment on HiFi (RB1320541) we measured the ALC spectrum of the Fe2(µ-pdt)(CO)4(PMe3)2 model hydrogenase complex over multiple temperatures. The spectra...

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...

Previous ALC measurements of the Fe2(pdt)(CO)4(PMe3)2 and [Fe2(pdt)(CO)4(CN)2]2- (referred to as 1 and 2) model hydrogenase subsites have yielded some intriguing results (RB...

The electron donor molecule BEDT-TTF (ET) provides a versatile building block for constructing molecular metals, superconductors, magnets and quantum spin liquids. A common...

We have recently performed high field ALC measurements on the polycrystalline Metal Tris(Hydroxy-quinolate), MQ3, series in order to further investigate the intrinsic electron...

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¿...

Using muon spin relaxation and ALC resonance spectroscopy the electron spin relaxation and mobility of the polymer P3HS will be measured as a function of temperature. The...

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...

We plan to confirm that the change in asymmetry on resonance in the ALC spectra seen in the subject complex dielectric during the previous rapid access proposal (RB1900028) is a...

Avoided level crossing muon spin resonance (ALC-muSR) is an exceptional tool for determining the structure and probing the dynamics of radicals but there have been only a few...

The study of organic ferroelectrics based on mixed-stack charge-transfer salts is currently a rapidly developing research field. These materials attract interest as highly...

The new molecular magnet bis(2,3-dimethylpyridinium) tetrabromocuprate (DIMPY) is a strong-leg spin ladder with a quantum critical point at 3.0(3) T separating a low-field...

We have observed an anomalous monotonically increasing longitudinal field relaxation rate in LiY_(1-x)Ho_xF_4 for applied fields above 1000 G (along the c-axis) and at a...
