Molybdenum based-oxides have recently attracted interest for use as electrolyte and electrode materials in Solid Oxide Fuel Cells. This proposal requests 5 days of beamtime on...

Complex oxides within the family CeNbO4 have been shown by single crystal x-ray studies to have superstructured average structures, but little detail has been obtained about the...

Magnetic cooling has recently become the focus of cooling system technology as it boasts important advantages in terms of power consumption and for the environment e.g. not...

The main aim of the proposed experiment is to probe the cation distributions in a series of half-Heusler A(MZ) intermetallic phases that are considered for use in thermoelectric...

We have recently observed extraordinary polymorphism on cooling various sodalites under vacuum. Materials undergo a phase transition followed by a fully reversible...

There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap andsafe cathodes. Recently, silicate-based cathodes have been described,...

Lithium transition metal nitrides Li3-xMxN (M=Co, Ni and Cu) have been reported previously as promising anodes for Li-ion batteries. The most promising compound in this family...

There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap and safe cathodes. Li2FeSiO4 shows promising performance as a cathode but...

We have prepared some new highly crystalline mixed-metals oxides using mild hydrothermal reaction conditions. Some of these are doped niobates, related to the important...

There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap and safe cathodes. Recently, silicate-based cathodes have been described,...

Very recently, the metastable cubic ice phase was renamed to stacking-disordered ice (ice Isd) in order to emphasise the fact that this form of ice contains not only cubic...

Group 1 amides of general formula MNH2 are some of the most promising materials for hydrogen storage applications due to their relatively low temperatures of hydrogen evolution...

Considerable effort is currently given to investigate proton conducting electrolyte materials for intermediate temperature range (200-500 °C) fuel cells (ITFCs). This proposal...

Intercalation electrodes operating close to 1V vs. Li+/Li are highly desirable. They are safe and provide protection to plating Li if overcharged, while still giving a...

Y-doped BaZrO3 has been identified as a promising potential candidate as an electrolyte materialfor proton conduction in intermediate temperature fuel cells. In the temperature...

This proposal requests 6 days beamtime on the Polaris diffractometer to study the nature of the local structure within two systems which have been reported to show a solid...

The physical properties of the post-perovskite phase of MgSiO3 control the dynamics of the lower thermal boundary layer of the Earth¿s mantle, but many of these properties...

The polycrystalline ceramic BiFeO3 - PbTiO3 is both ferroelectric and antiferromagnetic for a wide range of compositional space. We have shown in previous experiments that (1)...

NaAlH4 has been a model system for metal hydride hydrogen storage materials since the reaction was identified to be reversible. The decomposition pathway has been described by a...

Ni-based secondary batteries are currently used in many applications, however, the structural changes at the electrodes are not fully characterized and neutron diffraction is a...
