Unusual polymorphism in sodalites
We have recently observed extraordinary polymorphism on cooling various sodalites under vacuum. Materials undergo a phase transition followed by a fully reversible... -
Order-disorder and phase transitions in the LiFeO2 cathode materials
Despite the importance of the LiFeO2 phases as cathode materials in lithium ion batteries, little is known about their crystal structures, except that they should be based on... -
A variable temperature study of polymorphism in Li2+2xM1-xSiO4 electrode mate...
There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap andsafe cathodes. Recently, silicate-based cathodes have been described,... -
The Definitive Sodium Niobate Phase Diagram?
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... -
Exploring local structure in hydrated LiRAPs using pair distribution function...
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... -
Local atomic and magnetic structure of multiwall carbon nanotubes continuousl...
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.... -
Neutron reflectivity investigation of hydrogen in barrier oxide-coated Duplex...
The need for structural materials that can resist hydrogen assisted degradation becomes critical for the continuation of the development of the hydrogen economy. Hydrogen... -
Investigation of glycolide-h4 and d4 at high pressure.
This proposal seeks to investigate the polymorphism and polymerisation of glycolide. Glycolide is a six-memebered ring structure that polymerises into poly(glycolic acid) and is... -

Single Crystal Investigations of Polymorphism and Disorder in CH3NH3PbI3
Photovoltaics are one of the most promising technologies for meeting future energy requirements. CH3NH3PbI3 was first used in a solar cell in 2009, which gave an efficiency of... -
The short hydrogen bond in organic crystal structures revisited: (T,p) phase ...
Very short hydrogen bonds (with O···O separations <2.5Å), in which the position and behaviour of the protons are often ambiguous, have been the subject of many studies by... -
Study of the dynamics of lyophilized protein/bioprotectant systems
Developing recombinant protein pharmaceuticals has proved to be very challenging because of both the complexity of protein production and purification, and the limited physical... -
Dynamics of Polymer/Polymer nanocomposites
By adding only about 1% of soft polymer nanoparticles to natural rubber, a dramatic decrease in the viscosity (more than 50%) is induced. Our recent time of flight measurements... -
Neutron diffraction study of local and mesoscopic disorder induced by La and ...
The accurate determination of the defect structure of rare earth (RE) doped ceria solid electrolytes is fundamental for the comprehension of oxygen diffusion and charge... -
Complexity in simplicity: disentangling Pb2+ disorder in PbS, PbSe and PbTe
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... -
Aza-crown-stabilized Alkali-Alkalide Systems: Solvent and metal effects on di...
We request 4 days on IRIS to investigate the diffusional and rotational dynamics of the alkalide forming, fully methylated aza-crown hexamethyl-hexacyclen (HMHC) in... -
Structures of New Niobates Prepared by Hydrothermal Synthesis
We have prepared some new highly crystalline mixed-metals oxides using mild hydrothermal reaction conditions. Some of these are doped niobates, related to the important... -
Interactions of polyfluorinated substances with a phospholipid bilayer
Poly- and perfluoroalkyl substances (PFASs) have been used in various industrial applications and consumer products, but have received increasing global concern due to their... -
Neutron scattering studies of novel multiferroic materials
This project lies on the study of multiferroic materials in which both electric dipole order and magnetic order coexist. These materials are of the potential for new technology... -
Structural and magnetic orders in Ga-V oxide spinels
In certain materials, notably with the spinel structure, orbital ordering can result in the formation of a ground state with electrons delocalising between small numbers of...
