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 seek to continue our study of CsNiCl3 to determine the nature of the two magnetic transitions.Previous experiments at PSI have shown there are two distinct muons sites, one...

Recent advances in energy materials have led to the development of high capacity insertion cathodes for Li-ion batteries. One of the most promising of these materials is lithium...

Recent progress in the field of molecular magnetism has shown the clear potential for gaining control over the structural building blocks of molecular materials in order to...

An all solid state lithium ion battery (SSLIB) has an advantage in electrical capacity compared to the popular lithium ion battery (LIB) using a liquid electrolyte. However, a...

Muon spin relaxation will be used to study the low temperature magnetic properties of a new metal-oxalato-framework compound [(C2H5)3NH]2Cu2(C2O4)3. This has a three-dimensional...

This proposal describes a continuous experiment for a muSR study of a Li-ion battery cathode sheet. In the previous experiments, we used powder samples peeled off from a cathode...

Radio Frequency µSR provides a direct method for accurately determining muon hyperfine coupling constants, Aµ, for muoniated radical species. The method complements the well...

The quantum spin liquid (QSL) state is one of the possible outcomes of quantum fluctuations advancing magnetic systems into a disordered phase. After more than 30 years of quest...

Proton-conducting polymer membranes have significant technological applications in hydrogen or methanol fuel cells. muSR can shed light on the mechanisms for proton transport in...

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...

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...

The fluorinated ionomer Nafion is a material that provides efficient proton conducting membranes for application in important technological areas such as hydrogen fuel cells....

Hydrogen storage materials with a low working temperature are strongly required for the application of the next generation on-board hydrogen storage system. Among several...

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...

It has been suggested that within green dipotase there the magnetism is dominated by quantum flucuations but evidence for this is not definitive. This means that in this...

Topological insulators (TIs) are of inherent interest as they are conducting on the surface whilst insulating on the bulk. We would like to investigate magnetically doped...

Frustrated compounds belonging to the pyrochlore family have attracted significant interest as they can host a huge variety of exotic phases. In order to explore the rich phase...

Recently, we have found a new multiferroics material FeTe2O5Br, with simultaneous ferroelectric and incommensurate magnetic orderings appear at TN = 11 K. Our neutron...

This proposal describes a muSR experiment on Li-deficient Lix(Ni1/3Co1/3Mn1/3)O2 to determine a Li diffusion coefficient as a function of the Li content x, because muSR is a...
