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...

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...

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...

Repolarisation and level crossing resonance will be studied for several different oxalate compounds where muon radical states are known to be formed. Such compounds form a...

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...

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...

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...

The elusive OMu radical is believed to be formed by muonium reaction with nitrous oxide but has never been directly observed. It would be invisible to transverse-field muon spin...

Nitrous oxide, N2O, is an inhalant anaesthetic with a long history of use dating back to 1844. It is most commonly used as a light sedative in dentistry, or in child birth and...

The relative importance of factors affecting the low temperature ALC spectra of organic molecular systems such as polymers and small molecules is a topical issue. Polybutadiene...
