NaNbO3 has long been regarded as the 'most complex' perovskite known, with at least seven different phases reported as a function of T, at least two of which have evaded all...

Many of the devices currently used for energy storage (e.g., batteries, solar cells) use liquid electrolytes that are known to pose a serious fire and safety risk. In recent...

We propose to study a novel nanostructure consisting of multi-walled carbon nanotubes continuously filled with a single crystal of Fe3C using total neutron scattering on NIMROD....

Shale is an increasingly viable source of economic quantities of natural gas worldwide. Most of the gas is contained within the fine pores, thus characterizing accessibility and...

Co-crystals of 4-methylpyridine and pentachlorophenol (MP-PCP) exhibit the very unusual property of isotopic polymorphism, formation of different phases by samples differing...

Magnetic nanoparticles (NPs) are nowadays investigated comprehensively. Our TbCu2 NPs show a core-shell structure in which the core orders antiferromagnetically and the shell is...

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 propose to examine the structure of anatase titanium dioxide (TiO2) obtained by different synthetic techniques (including hydrothermal and sol-gel) and of different particle...

2 days of beamtime is requested on Polaris to study the defect structure of an oxide-ion conductor Bi1-xBaxFeO3-x/2. RT total neutron scattering studies on samples heat treated...

We ask for 5 days on SXD to study the detailed crystal structures of PbS, PbSe and PbTe to resolve long-standing, topical controversies about the detailed behaviour of this...

New perovskite phases containing lead and halogens with a molecular cation are providing new options for materials in solar cells, giving unusually high efficiencies in...

We will investigate the structure of 4-chloroimidazole a material which undergoes extreme anisotropic thermal expansion. This is believed from our initial X-ray data to be due...

Perovskites are used in many applications such as electrode materials in fuel cells or as catalysts e.g. in syngas conversion, CO oxidation, N2O decomposition, or...

The mechanism of high temperature superconductivity (HTSC) remains unresolved. Of particular interest is the origin of the mysterious pseudogap (PG, a partial gap in the...

Tetragonal R(Fe,M)12 compounds (R=rare earth, M transition metal or Si), with the ThMn12 structure, are good candidates as permanent magnet materials with reduced R content....

Zinc sulfide nanoparticles have a wide range of potential applications, in particular due to their optical properties. Research has enabled ZnS nanoparticles to be prepared with...

Usual structural hypothesis related to superionic glasses containing metal halides MY = LiI, NaBr, AgI, etc., implies the absence of chemical interactions between the host glass...

Measurements are required for Sans2d resolution checks and also the overlap of the two Sans2d detectors. Proposal submitted to panel and they deemed it should be done as...

Quantum spin liquids are novel magnetic states in which quantum entanglement suppresses conventional magnetic order. Understanding the effects that stabilise such states is an...

ReO3 is a well-known oxide framework with unusual thermal expansion behaviour, exhibiting multiple regions of both positive and negative thermal expansion (NTE). We propose to...
