Understanding pressure-driven structural changes in FePO4-II
The room temperature high pressure behaviour of FePO4-I has been investigated and a phase transition at around 2.5 GPa to the orthorhombic phase (FePO4-II) accompanied by a... -
High Pressure Structure of Carbonic Acid
Recent published studies have identified a stable solid form of carbonic acid at high pressure. This proposal is for beamtime to collect the data to solve its crystal structure. -

Neutron scattering investigation of the influence of high hydrostatic pressur...
Amyloid fibrils are highly organized filamentous structures formed by the self-assembly of polypeptides. This proposal is to study the effect of pressure on the structure of... -
The high temperature high pressure behaviour of ammonia hydrates
Ammonia hydrates are important constituents of the outer solar system. In recent x-ray studies we have found evidence for a solid solution between ice and ammonia at high... -
Pressure-temperature phase diagram of of the Jahn-Teller transition in LaMnO3
The parent compound LaMnO3 of the hole-doped colossal magnetoresistance materials La1-xAxMnO3 (A = Ca, Sr, Ba etc.) has attracted much interest from condensed matter scientists.... -
Polyamorphism in Glassy GeO2
The object of this proposal is to determine, by using neutron diffraction, the nature of the polyamorphic phase transition that occurs in glassy GeO2 with increasing pressure.... -
Phase evolution in the transition from epsilon to gamma glycine
Glycine, the simplest naturally-occurring amino acid, exhibits unusually extensive phase diversity. Three polymorphs are known under ambient conditions. Each shows different... -
The high-pressure structures of carbon dioxide hydrate
The gas hydrates offer potential as hydrogen and carbon dioxide storage materials for use either in transport applications or for carbon sequestration. We have discovered a... -
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... -
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... -

Phase Behaviour in Pyrazine and Tetramethylpyrazine.
Pyrazine-I is stable < 302 K, phase II exists from 302-310 K, and phase III from 310-324 K. The known phase-I forms an ordered structure. It is thought that structures of...
