Determination of the structure of SiO2-rich aqueous fluids at high temperatur...
Many geological processes are governed by the migration of hot, mineral-rich water. These "hydrothermal" fluids are stable at high pressures and temperatures and are important... -
Investigating the formation of novel mixed amide-imide complexes and understa...
Inexpensive light-metal amides are among the most highly active and effective ammonia decomposition catalysts at modest temperatures and are likely to surpass the performance of... -
Dynamics of Solid Ionic Conductors: Na2Si2O5 and Li2Si2O5
We would measure vibrational spectra for Li2Si2O5 and Na2Si2O5, as well as quasielastic neutron scattering (QENS) spectra for Na2SiO5. The measurement of phonon spectra in the... -
INS Study of Cu-based methanol synthesis catalysts
In low-pressure methanol synthesis from fossil synthesis gas, Cu/ZnO/Al2O3-catalysts are successfully used in industrial synthesis at 250°C and 50-100 bar, but the exact... -
A high-temperature neutron powder determination of the phase transition and c...
Cu2ZnSnS4 (CZTS) is a solar cell material of great interest. However the material when fabricated, although of high symmetry, contains substantial defect concentration and a... -
Pressure dependence on the isomorphic phase transition in KOs2O6
We are requesting 5 days of beamtime on HRPD to measure powder diffraction patterns of KOs2O6 under He gas high pressure up to 150 MPa. KOs2O6 exhibits a novel phase transition... -
In-situ study of magnetic structure for Ho2(Fe,M)17 (M =Si, Ni and Al) alloys
Metallic materials that exhibit negligible thermal expansion or zero thermal expansion (ZTE) have great merit in practical applications. However these materials are very rare... -
Structural determination of non-stoichiomentric phases Li2+yND for 0<y<1
In a series of in situ neutron diffraction measurements from deuterium up-take in Li3N, the present authors have identified a novel non-stoichiometric 'quasi-imide' of... -
Structure of multi-component mixed metal molybdates by neutron diffraction
Our general aim is to understand the defect structure of complex oxides in ternary oxide systems, which are known to be effective selective oxidation catalysts. For this purpose... -
Magnon dispersion in the polar ferrimagnet BaCaFe4O7
Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices;the inherent magnetoelectric effect can underpin both pyroelectric or... -
The use of INS to characterise prototype methane reforming catalysts over a r...
Previous work by the experimental team has successfully examined methane reforming catalysts using CO2 as the oxidant. Unfortunately, the progression to using steam as the... -
Determination of the magnetic interactions of low-dimensional binary metal th...
Magnetic molecular framework materials, where the magnetic metal centres are linked together by molecules rather than single atoms, are a very exciting class of materials, as... -
Local structure study of Cr-Fe alloys with enhanced magnetovolume effect
Negative thermal expansion (NTE) materials, the volume of a material abnormally contract with the increase of temperature, is closed related to the magnetovolume effect in... -
INS Study of Molybdenum Clay Hydrodeoxygenation Catalyst: Effect of Promoter ...
The Indonesian government has pledged to ensure that all gas stations in Indonesia switch from diesel fuel to a biofuel blend produced from palm oil by 2025, as part of its... -
In-situ studies of alkaline earth nitride deuterides
Heavy alkaline earth nitride hydrides (AE2NH, with AE = Ca and Ba) are of interest due to their potential suitability as electrolyte materials in a variety of electrochemical... -
Phase transitions in non-centrosymmetric Dion-Jacobson Phases
Ferroelectric materials - those which exhibit a spontaneous and switchable electrical polarization - have a wide range of applications. However materials which exhibit... -
High resolution INS spectra of hydrocarbonaceous overlayers formed on novel m...
For the first time, the research team aim to use INS to characterise a series of new high specification methane reforming catalysts. The enhanced performance of these catalysts... -
