Towards the Calibration of Chemical Pressure
The application of hydrostatic pressure allows the precise tuning of atomic separations, which control electronic structure and virtually all the interatomic interactions that... -
Monitoring the changes in the local environment of titanium in modified netwo...
In this experiment we aim to evaluate the structure of titanium-rich glasses as they are compressed. In a previous experiment we have collected data for K2TiSi2O7 glasses with... -
High Pressure Behaviour of Benzene
The interactions between benzene molecules in the solid phase is of fundamental interest. Benzene is often used as a model system for structure prediction methodologies and... -

Determination of the structure of SiO2-rich aqueous fluids at high temperatur...
Many geological processes are governed by the migration of hot, mineral-rich water. These "hydrothermal" fluids are stable at high pressures and temperatures and are important... -
Structure of hot dense liquid carbon dioxide
We propose to study the structure of liquid CO2 by neutron diffraction under high pressure and high temperatures to 6 GPa / 800 K. Carbon dioxide belongs to the most fundamental... -
Pressure-induced high-spin low-spin transition in MnS2 and MnTe2
Pressure induced high-spin (HS) to low-spin (LS) transition in MnS2 was speculated by Chattopadhyay and von Schnering more than twenty years ago from their high pressure X-ray... -
Temperature-induced proton migration in an energetic co-crystal
The results of these studies will provide valuable information on the effects of temperature on the structures of an energetic salt and co-crystal formed between nitrotriazolone... -
Density-driven structural transformations in boro-germanate glass
The resistance of glass to fracture is crucial for its use as a structural material in fields ranging from engineering to architecture. Here, B2O3 can play a crucial role in... -
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... -
The high pressure structure of cobalt-bearing silicate glasses
The aim of this proposal is to examine the pressure induced changes in the structure of two cobalt-bearing silicate glasses. Transition metals such as cobalt can adopt different... -
Investigation of new phase, MnBi2, by in situ high-pressure neutron diffraction
Permanent magnets are essential for renewable energy technologies such as electric cars and wind turbines. Global demand for magnets is increasing, however, the elements used to... -
Effect of pressure-transmitting medium on the phase transformation of para-am...
The pressure-transmitting medium in a high-pressure experiment is usually thought of as an inert medium that allows the sample to be compresses rather than crushed. In organic... -

The application of hydrostatic pressure allows the precise tuning of atomic separations, which control electronic structure and virtually all the interatomic interactions that... -
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... -
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.... -
Unravelling the temperature-pressure phase diagram for the multiferroic, BiFeO3
Bismuth ferrite is arguably the most widely studied multiferroic material due to room temperature magnetic and ferroelectric ordering. However, despite extensive research the... -
Effect of pressure on the ice XII to ice XIV phase transition
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... -
Structural analysis of Kitaev spin liquid candidate beta-Li2IrO3 under pressure
The theoretical predication of Kitaev spin liquid in honeycomb iridates triggered tremendous interests. We recently discovered a new candidate material, beta-Li2IrO3 with a 3D... -
