Apatites are currently of major interest in a number of fields: biomaterials, solid oxide fuel cells, catalysis, environmental remediation to name a few. Hydroxyapatite -...

We have recently demonstrated that we are able to obtain structural information about adsorbed hydrogenous species from a variety of metal catalysts. We emphasise that this is a...

The recent interest in carbon-based materials like graphene stimulated a deeper analysis of the magnetism in graphite defects. In a previous µSR experiment we observed an...

Iron-based superconductors (FeSCs) have been an essential research area in condensed matter physics. Spins of iron sites forming a long periodic configuration, called the...

Replacing Na ions in NaxCoO2 with divalent Ca ions results in the formation of ordered arrays of divacancy clusters, rather than the trivacancy clusters found for the pure...

Bismuth oxide based electrolytes have been widely studied due to their high oxide ion conductivity. The d-phase of Bi2O3 shows the highest known oxide-ion conductivity of any...

When fluids are confined in pores with dimensions in the nanoscale, their properties differ from the bulk mainly due to the solid-fluid interactions and the finite pore size....

In collaboration with Sasol Technology UK Ltd, the research team have previously used INS to investigate the surface chemistry of synthesis gas (CO + H2) over a series of...

We propose measurements of the elementary phonon-roton (p-r) excitations of liquid 4He confined in porous MCM-41 (45 Å pore diameter) at wave vectors Q ¿ beyond the roton¿, 2.4...

On the basis of X-ray diffraction the oxygen deficient La2-xNdxCe2O7 series displays a transition from disordered fluorite to the C-type superstructure in which the cations...

We wish to complete muon spectroscopic experiments on materials from a ceramic system of interest for possible solid electrolyte applications in lithium-ion battery devices:...

Electrolytes based on pyrochlores such as Ln2M2O7 (M = Ti, Zr, Hf) have attracted attention due to their relative stability combined with relatively high ionic conductivity at...

It is commonly accepted that the recording of holograms with atomic resolution requires singlecrystalline samples. Closer analysis, however, shows that the reduced information...

This beamtime request is part of a long term project based on the liquids diffractometer SANDALS and aimed at developing the use of Paris-Edinburgh press for liquids and in...

The organic salt guanidinium mesylate [Gdm][CH3SO3] is a promising phase change material for thermal energy storage applications. It has melting point Tm = 208 °C, and...

Standard diffraction studies of PrBCO and YBCO show that these two compounds are isostructical. However, if any Pr/Ba disorder is present in PrBCO, the diffuse scattering signal...

Here we propose to study the local structure of sodium in standard organic carbonate electrolytes for sodium ion batteries. Three different electrolytes are chosen to study; a...

Most of Nd-pyrochlores show all-in-all-out long-ranged order ground state at low temperatures. Recently unconventional slow spin dynamics are reported in the paramagnetic state...

To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently...

In the vicinity of x ~ 0.75, LixCoO2 has potential as a thermoelectric, since it has a high Seebeck coefficient and metallic conductivity. We have performed the first successful...
