Structural investigation of the high temperature phases in ammonium iodate
We will investigate the structures of the high temperature (RT to 400K) phases of ammonium iodate, and the features that accompany these phase transitions. From our previous... -
In-situ reaction of lithium amide or imide with manganese(IV) oxide
We request 3 days beam time on POLARIS for in-situ powder diffraction studies of the reactions of lithium amide or lithium imide with manganese(IV) oxide under flowing argon or... -
PNR determination of magnetic interface states and exchange coupling in hybri...
The atomic interfaces between ferromagnetically ordered thin films with perpendicular anisotropy and either films with magnetically ordered in-plane anisotropy or a non-magnetic... -
Probing diffusion of renewable feedstocks in single-site nanoporous materials
Silicon-doped aluminophosphates (SAPOs) are framework materials similar to zeolites. Their pore structure and solid acid sites contribute to their activity and selectivity in... -
Magnetic ordering in new multi-anion solids: Sr2Fe3Se2O3 and Sr2Cr3As2O2
We have identified new multi-anion solids with transition metals in unusual coordination environments and with apparently complex magnetic ordering. This experiment proposed for... -
Reentrant Structural Transitions and Collapse of Charge and Orbital Orders in...
A-site ordered quadruple perovskites, AA3B4O12, show many interesting physical and chemical properties, for example, inter-site charge transfer and disproportionation, giant... -

Molecular Dynamics in Polymer Nanocomposites
Our aim is to determine whether the fast dynamics, of either the backbone or the phenyl ring of polystyrene, are altered by the presence of carbon nanotubes, and, if so, whether... -
A new plastic phase in PCBM from low-energy inlelastic neutron scattering
Phenyl-C61-butyric acid methyl ester (PCBM) is a fullerene-based material of high technological interest due to its use in organic solar photovoltaic cells. A better... -
Towards the development of carbonitrides as novel two-stage regenerable reage...
We are examining a number of cobalt-molybdenum carbonitrides as possible catalysts for reactions that produce nitrogen-containing organic molecules. There is good evidence that... -
High temperature superstructures in thermoelectric oxides
Sodium cobalate has emerged as one of the best thermoelectric materials. Our previous neutron Laue diffraction studies on SXD have found ordered arrays of multivacancy clusters,... -
Hydrogen from ammonia using lithium imide metal nitride composites
Light metal amides and imides are a new class of highly active ammonia decomposition catalysts. Indeed, composites of lithium imide and transition metal nitrides are likely to... -
Molecular motions in novel water-soluble organometallic gels
The aim of this proposal is to study the internal dynamics of a novel organometallic polymers based on two metal-containing moieties -Ru, Au- bridged through a tridentate... -
In-situ neutron powder diffraction studies of non-stoichiometry in Na battery...
We request 3 days on POLARIS to study the detailed crystal structure of a sodium battery cathode material that is currently under consideration for use in commercial sodium... -
SEGMENTAL DYNAMICS OF LINEAR AND CROSS-LINKED POLYISOPRENE IN NATURAL RUBBER
The aim of this experiment is to explore the segmental mode of natural rubber NR by means of quasielastic neutron scattering, QENS, and observe the influence of natural... -

Monomer dynamics in polymer nanocomposites
We have recently shown that the addition of single walled carbon nanotubes produces a minimum in the diffusion coefficient with increasing nanoparticle concentration. Initially,... -
Total Scattering Study of Caesium and Thallium Azides
This proposal seeks to conduct total-scattering studies on thallium and caesium azides to investigate the effect of temperature on the atomic motions, particularly of the azide... -

Are La3Ni2NbO9 and La3Ni2TaO9 relaxor ferromagnets?
A relaxor ferroelectric exhibits a net polarisation only in an applied electric field due to the co-alignment of polar nanoregions. In La3Ni2SbO9 we found the magnetic...
