Single-Crystal Neutron Diffraction Study on [U(C5Me5)2(H)(mu¿H)]2
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... -
Ion Exchange and Dehydration in Clinoptilolite
Determination of the position of hydrogen in inorganic materials such as zeolites, coordination compounds, H2 storage materials, energy materials, organometallics etc is a... -
Search for antiferromagnetic coupling in ferromagnetic oxide LSMO-LCMO multil...
La0.7Ca0.3MnO3 (LCMO) and La0.7Sr0.3MnO3 (LSMO) are two oxide ferromagnetic materials. They will be grown on single crystal SrTiO3 substrate. This allows a highly textured... -
Polymorphism and Li coordination in LiFeO2 ionic conductors
Despite the importance of the LiFeO2 phases as cathode materials in lithium ion batteries, little is known about their crystal structures. In the frame of our research project... -
Investigation of non-Fermi liquid behaviour in Mn0.75Fe0.25Si through muon sp...
The investigation of electron correlations in intermetallic alloys is fascinating. At times, depending on the nature and strength of correlations, the compounds exhibit... -
Kinetics of Molecular Intercalation into Graphite Oxide
The search for new porous materials is increasingly be driven by socio-economic pressure to diversify our energy supply and minimize environmental impact. Carbon-based... -
The Structure of Ca- and Yb-ammonia Solutions: Polarons, Bipolarons and Elect...
In this experiment we propose to perform diffraction on isotopically substituted samples of Ca/Yb:ND/H3 and Ca/Yb:15ND3 at two concentrations (8 and 2 MPM) using the new NIMROD... -
Framework flexibility and host-guest hydrogen bonding in the metal-organic do...
The recently reported double perovskite analogue imidazolium potassium iron(III) cyanide is noteworthy for two reasons. First, the order-disorder phase transitions, in which the... -
Low Temperature Structural Investigation of the Triangular Lattice Material T...
The room temperature crystal structure of TbInO3 realises a geometrically frustrated two-dimensional triangular lattice of Tb3+ J = 6 cations. We have prepared ~ 6 g of high... -
Effect of pressure on the ice XII to ice XIV phase transition
Water ice displays a remarkably complex phase diagram containing pairs of hydrogen-ordered / disordered phases. Ice XII is a hydrogen-disordered phase and ice XIV is its... -
Using small angle neutron diffraction to describe the status of water in solu...
Fish oocytes and embryos are complex cryobiological objects for which, successful cryopreservation has still not been achieved. This circumstance seriously restricts the... -
Multiscale studies of crystallisation in synthetic polymers
We wish to exploit the unique capability of Nimrod to move forward the long standing issue of the way in which long chain polymers crystallise. For synthetic polymers there are... -
Influence of structure on the enigmatic thermal properties of a new layered o...
Thermoelectric (TE) materials are set to play an increasingly important role in the development of new energy efficient technologies by generating electrical current from waste... -
Micropore Collapse in Bulk Amorphous Solid Water
We propose to study the influence of deposition rates and annealing effects on microporous amorphous solid water samples (ASW) using NIMROD. The data will allow us to monitor... -
Understanding Molecular Host-Guest Interactions in Functionalised Metal-Organ...
We aim to perform inelastic neutron scattering (INS) measurements at the TOSCA spectrometer to study the vibrational behaviour of designer Guest@MOF composite systems (e.g.... -
Principal Component Analysis of Phase Behaviour on the Upgraded TOSCA
Principal Component Analysis (PCA) is a powerful chemometric tool for the analysis of multivariate datasets. Capitalising from the recent upgrade of the TOSCA spectrometer, we... -
Topotactically reduced phases containing square planar Co(II) centres
The topotactic reduction of Sr3Co2O5Cl2 and Sr3Co2O5.80 yields the Co(II) phases Sr3Co2O4Cl2 and Sr3Co2O5 respectively. These phases contain corner linked arrays of... -
Structural studies of the KSbO3-type osmates Sr6Os6O19 and Bi3Os3O11
Osmium-based oxides show a wide range of interesting properties due to the variety of oxidation states osmium can adopt combined with 5d electrons displaying strong spin-orbit... -
Test experiment: Neutron diffraction on helium in silica
We request 3 days of beamtime on GEM to attempt to perform neutron diffraction on helium inside vitreous SiO2. Significant amounts of helium can be dissolved into the glass... -
A muSR Investigation of the Magnetic Ground State and Spin Dynamics in the Tr...
In a typical magnetic material the interactions between neighbouring magnetic moments will tend to lead to their ordered alignment throughout the entire structure as it is...
