The quest for fully hydrogen-ordered ice XIV
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... -
Pressure driven phase transitions in antiferroelectric, PbZrO3
Antiferroelectric materials are attracting extensive attention due to their potential in energy storage applications. These materials exhibit a double polarisation-field... -
The icy-moon analogue of MgSiO3-perovskite: MgSO4.9H2O a high-pressure study
Mg-sulfate 11-hydrate (meridianiite) is decomposed by pressure to form Mg-sulfate 9-hydrate + ice, a process that will occur in the mantles of large icy planetary bodies and... -

Thermoelastic properties of ammonium sulfate, (ND4)2SO4, and the P-T dependen...
Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crystal. There have been no... -
Equations of state of D2O ice III and ice V
The high-pressure forms of ice, phases III and V, are the equilibrium solids in contact with liquid water at pressures between 2.5 - 5.5 kbar. Consequently, their properties are... -
Insulator to metal transition in TiOCl at high pressures
We propose to study the high temperature structure of TiOCl where a pressure induced metal to insulator transition has been reported recently by Kuntscher et al.Due to our... -
INS study of the effect of particle size on the formation of beta-palladium h...
Finely divided, supported palladium particles are used as catalysts in many technical processes. However, there is still considerable potential to improve catalyst performance... -
A High Pressure Study of Para-Xylene
This proposal will explore the effect of elevated pressure on para-xylene. It is a raw material in the large scale synthesis of various polymers, including polyethylene... -
Commissioning of a new continuously-loaded high-pressure piston-cylinder cell
We request two days on Engin-X to carry out commissioning tests on a pair of new piston-cylinder cells and their associated hydraulic press. Although intended primarily for use... -
High pressure charge transitions in PbCoO3
PbCoO3 used to be the missing link in the PbMO3 perovskite series. PbCoO3 was recently synthesized by the Azuma group using high-pressure synthesis at 12 GPa. NPD at JPARC... -
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... -

Pressure-induced proton migration in an energetic co-crystal
The results of these studies will provide valuable information on the effects of extreme conditions on the structures of an energetic salt and co-crystal formed between... -
Comparison of the Compression Behaviour of BaSnO3 and Ba0.575Sr0.425SnO3
We propose to study the effect of pressure on the structure of the tetragonal Ba0.575Sr0.425SnO3, The behaviour will be compared to the compression of the cubic BaSnO3 (parent... -
Ionic disorder studies of lightweight hydrides by VESUVIO
We ask for 8 days on VESUVIO to study the momentum distribution of LiBH4, Li2NH and Li1+xNH2-x as a function of temperature from 10K-653K (depending on sample). Li2NH and... -
Determining elemental phosphorus contents in bloomery iron standards as a fun...
The proposed measurements aim to determine the behaviour of the structural parameters of iron-phosphorus alloys as a function of P-content, in order to have a reliable... -
High pressure structural study of BaD2
Simple hydrides are of scientific interest due to their suitability for storage of hydrogen in the solid state. These materials also display a wealth of interesting physics,... -
High-Pressure Investigation of the Ferroelectric ND4IO3
We propose a high-pressure neutron powder diffraction study of the crystal structure of deuterated ammonium iodate, ND4IO3, which is known to undergo a ferroelectric phase... -
Low temperature, high pressure phase transition of the Improper Ferroelectric...
We have found that the 134-perovskite, HgMn7O12 (HgAMnA3MnB4O12) exhibits improper ferroelectric coupling due to an unusual orbital ordering of the manganese cations on both...
