The ferroelectric phase transition in Dion-Jacobson layered perovskites - con...
Ferroelectricity in the Dion-Jacobson (DJ) family of layered perovskites arises from a 'trilinear coupling', whereby two non-polar lattice modes interact in such a way to... -
YMnO3-x : Mn(I) in a mixed metal oxide ?
Topotactic reduction of YMnO3 with CaH2 yields three new reduced phases. Two of these phases appear to have compositions close to YMnO2.5 but with very different anion vacancy... -
Non-destructive characterization of lunar and martian meteorites
The aim of the present work is to place the meteorites found on Earth back onto the Moon or planets from where it is assumed they come. In this context, to approach the above... -
Understanding the "post-perovskite" structure (I): the Behaviour of CaPtO3 at...
Recently, our view of the Earth¿s lower mantle changed dramatically. It had been thought that two major phases were present throughout all of the lower mantle:... -
Structural Aspects and Magnetic Order in Fe based perovskite oxide fluorides ...
In this work, we will investigate the structures (crystallographic and magnetic) of Mn5VO8 and a range of Fe containing perovskite oxide fluorides. In terms of the former, this... -
Mechanism of hydride-ion mobility in a novel oxide-hydride
This proposal requests 7 days of beamtime on the quasielastic neutron scattering spectrometer OSIRIS to investigate the mechanism of hydride ion mobility in the recently... -
Antibiotic paths through the bacterial outer membrane: The strange case of va...
Gram-negative bacteria, which cause a variety of diseases including meningitis, plague, sepsis and food poisoning, are becoming increasingly antibiotic resistant. One reason is... -
Resolving manifold setting dynamics in protiated and D2O based portland cement.
Previous NCS measurement on glass biocements revealed that setting is non-monotonic. Recent determinations using VESUVIO (2016-Apr) for Portland cements showed similar... -
Can INS measurements access hydrocarbonaceous overlayers on heterogeneous hyd...
This application seeks to discover whether the catalyst handling protocols refined for INS measurements of a variety of heterogeneous catalytic systems can be further exploited... -
Investigating the role of oxygen in the mechanism for the transformation from...
Materials for Solid Oxide Fuel Cells (SOFCs) are being developed continuously. Cuprous delafossites (CuBO2 where B=Cu, Cr) are being developed for cathode side applications in... -
Compressible Liquids
Liquids are commonly known to be incompressible. However, a recently invented class of materials called Porous Liquids, which exhibit permanent porosity in the liquid phase, may... -
Assessment of single crystal diamond detector response stability up to 250 °C
Neutron measurement and diagnostic is of paramount importance in fusion machines like the ITER Tokamak. Indeed the measurement of neutron yield and spectrum as well as that of... -
Ba3MoNbO8.5 novel oxide ion conductor: Direct observation of oxide ion dynamics
Oxide ion conductors are researched as electrolytes in solid oxide fuel cells. Yttria-stabilized zirconia is the currently used electrolyte in SOFCs, leading to high operating... -
Possible high-temperature polar phases in the [110] layered perovskites NdBaI...
Geometric ferroelectrics are an unusual and rare class of materials which exhibit spontaneous electrical polarisation due purely to 'geometric' effects, i.e. caused by atomic... -
Microstructural orientation mapping with a neutron beam
We propose to develop the means to measure the orientations, phases and strains of individual crystal grains within a polycrystal using neutrons. Such measurements have... -
In-situ stress relaxation during heat treatment in sub-scale forgings of Nick...
Advanced materials such as polycrystalline Ni superalloys put increased pressure on developing appropriate thermomechanical procedures, which avoid the generation of large... -
Na-Dynamics in Solid Ionic Conductors: 11Al2O3-Na2O and Na2Ti3O7
We would measure vibrational spectra as well as quasielastic neutron scattering (QENS) spectra for beta- alumina (11Al2O3-Na2O) and Na2Ti3O7. The measurement of phonon spectra... -
Monitoring of KTiOPO4 Crystallization with a New Supercritical In-Situ Hydrot...
This proposal seeks 2 days on POLARIS in order to fully complete the commissioning of a large volume in-situ reaction cell for studying hydrothermal chemical syntheses in... -

Shifting the tricritical point in CoMnSi
We have a long-standing interest in the temperature- and magnetic field-evolution of magnetic and crystal structure in CoMnSi. This is driven by an interest in the...
