Total scattering study of the orientational phase transition in para-terphenyl
There is currently a resurgence of interest in phase transitions in orientationally disordered molecular crystals. This is partly driven by the fact that new experimental and... -
Local structure, dynamics and magnetism of the phases of cobalt imidazolate
This proposal concerns the metal-organic framework (MOF), cobalt imidazolate. Imidazole (im) is a small, flat organic molecule that forms slightly bent metal-im-metal linkages,... -
Local structure of Sr-doped multiferroic bismuth ferrite
Bismuth ferrite, BiFeO3, is a much-studied ceramic showing both dielectric and magnetic ordering at relatively high temperatures. In order to improve its properties there has... -
Oxide ion vacancy distribution in A site substituted defect pyrochlores.
Electrolytes based on pyrochlores such as Ln2M2O7 (M = Ti, Zr, Hf) have attracted attention due to their relative stability combined with relatively high ionic conductivity at... -
Anomalous elasticity in negative thermal expansion materials
Recent experimental work on the negative thermal expansion material Zn(CN)2 has shown that the elastic stiffness is anomalously reduced on compression. That is, if B is the bulk... -
Local structure / electronic-structure relationships in functional materials
This proposal is a low-cost/high-gain first step in an ambitious project: namely, to develop a combined neutron scattering and electronic structure calculation approach as a... -
Solvation structure of sodium ions and hexa-fluorophosphate ions in organic c...
Here we propose to study the local structure of sodium in standard organic carbonate electrolytes for sodium ion batteries. Three different electrolytes are chosen to study; a... -
How molecular solids prepare for phase transitions: The phase transition in o...
Oxalyl chloride, which is a liquid at RT, forms a disordered phase (I) on cooling to 260 K. This phase is unstable with respect to an ordered phase (II) below 250 K, but in... -
Local structure of the ferroelectric and giant barocaloric (ND4)2SO4
Ammonium sulfate has a well-known order-disorder phase transition at -50 ºC: initially of interest for the ferroelectric behaviour in the low-temperature phase, this has... -
Solvation of sodium by glyme-based electrolytes for sodium intercalation into...
Here we propose to study the local structure of sodium ion in glyme electrolytes for sodium ion batteries. Glyme electrolyte are linear ethers of the structure... -
High pressure phase transitions in metal-formate perovskites
The family of guanidinium metal formates has the perovskite structure and, like many perovskites, is of interest for these materials' magnetic and electric properties, in... -
Phonon dynamics in liquid gallium
We propose to measure the inelastic scattering S(Q,E) maps from gallium in its liquid phases across a wide range of temperatures. This proposal is based on a new prediction for... -
Lithium ion distribution in lithium-rich lithium manganese polyphosphate elec...
The present proposal seeks to establish the conductivity mechanism in a series of lithium manganese polyphosphate glasses rich in lithium for potential use in all solid state... -

Here we propose to study the local structure of sodium in standard organic carbonate electrolytes for sodium ion batteries. Three different electrolytes are chosen to study; a... -
Structure of amorphous Porous Aromatic Framework 1
Materials that are porous at the atomic scale have proven to be important for many applications, including gas capture and catalysis. Recently it has become possible to make... -
Spontaneous strain and framework distortion in hybrid Prussian blue analogues
The metal-organic Prussian blue analogues (HIm)2K[M(CN)6], where HIm is the imidazolium cation and M = Fe or Co, have switchable dielectric constants, since the imidazolium ions... -
Network compression and pressure-induced amorphisation in Zn(CN)2
Zn(CN)2 is an important material because it shows isotropic NTE over a large temperature range and to an extent more than double that of ZrW2O8. This unusual behaviour... -
High pressure effects on Jahn-Teller distortion in metal-formate perovskites
The family of guanidinium metal formates has the perovskite structure and, like many perovskites, is of interest for these materials¿ magnetic and electric properties, in... -
Copy of: Abiogenic origin of methane: a neutron diffraction study
It has recently be demonstrated, through diamond-anvil cell experiments, that it may be possible for methane to be formed within the inner Earth through transformation reactions... -
