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... -

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... -
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 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... -
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... -
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... -
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... -
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...
