Compressibility and Tilting of Polyhedra within Sr2NiMoO6 at High Pressure
Ordered double perovskites (also known as elpasolites) have the general formula A2BBO6 where A is generally a rare earth metal or alkaline earth metal and where B and B are... -
Phase diagram of a switchable dielectric framework near the critical point
The family of hybrid Prussian blue analogues includes many electroactive materials, where organic cations moving within the pores of the cyanide framework cause unusual and... -
Single-crystal neutron diffraction study of sucrose at high pressure.
In the context of expanding the sample environments available for experiments on the SXD instrument, the Paris-Edinburgh press recently developed on PEARL offers the possibility... -
Phase transitions in melamine at high pressure
Melamine is a common organic molecule based on a six-sided ring; this unit typically connects with itself or other organic species to form layered crystal structures, which then... -
Local ordering in the pressure-induced order-disorder transition in ammonium ...
Ammonium bromide undergoes a pressure-induced order-disorder transition, where the disordered (plastic) phase is thought to consist of a random distribution of ammonium cations... -
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... -
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... -
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... -

The effect of pressure on the hydrogen bonding in ammonium formate
We propose to investigate the changes that occur in the structure of ammonium formate as a function of pressure. This is the simplest system in which the oxygen atoms of a... -
The phase stability of alpha-glycine at high pressure
Though the beta and gamma forms of the simplest amino acid, glycine, yield a variety of different phases on application of pressure, Raman data suggest that the most common... -
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... -
A High-Pressure Study of TNT
This proposal will explore the effect of elevated pressure on the widely used civil and military explosive TNT (trinitrotoluene). We are proposing a careful high-pressure... -
A High pressure investigation of the Binary carbonyls of group 7 M2(CO)10 M =...
The structures of two binary metal carbonyls containing a metal-metal bond Mn2(CO)10 and Re2(CO)10 will be studied as a function of pressure. Both these molecules undergo a... -
The high pressure structures of ammonium fluoride
Ammonium fluoride is an ionic H-bonded analogue of ice. Its behaviour is thus of interest as a comparator for ice. This proposal is for beamtime to make the first neutron study... -
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... -

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...
