Structural investigation of the high temperature phases in ammonium iodate
We will investigate the structures of the high temperature (RT to 400K) phases of ammonium iodate, and the features that accompany these phase transitions. From our previous... -
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... -
Understanding pressure-driven structural and magnetic properties in LaFeO3
This proposal is concerned with determining variations in the high pressure crystallographic and magnetic structure of LaFeO3. LaFeO3 is a characteristic example of... -
High pressure behaviour of ammonium carbamate
A number of compounds crystallise in the NH3-H2O-CO2 ternary system, including ammonium carbonates and carbamates, these being closely related to the water-deficient compound... -
Low dimensional networks under pressure. In-situ diffraction measurements of ...
Carbonate liquids are characterised by low temperature and low viscosity and play an important role in molten carbonate fuel cells, battery electrolytes and, surprisingly, in... -
High pressure phase diagram of water-methanol mixtures.
Alcohol-water mixtures are well known to possess a number of thermodynamic and transport properties that deviate from those of an ideal binary mixture. While the structure of... -
Towards Neutron Scattering of Amorphous Materials in the Gigapascal Regime
Over the past few years, extensive developments have been made in the use of neutron diffraction for structural studies of liquids and amorphous materials at high pressure.... -
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... -
Characterising the magnetic structure of Pd3Fe under pressure
Pd-Fe alloys are of interest due to the unusual interplay between the magnetic and mechanical properties they display. Examples include shape-memory effects in Fe-rich alloys,... -
The PVT equation of state of D2O ice III / IX
The high-pressure form of solid water, ice III, is the equilibrium phase in contact with liquid water at pressures from about 2.0 - 3.5 kbar. Consequently, its properties are... -
Investigating the magnetic structure of the solid solution PrCr(1-x)MnxO3
Rare-earth (A= La, Ce, Nd, Pr) orthochromites (A CrO3) and orthomanganites (A MnO3) are of interest due to the number of unusual physical properties they possess, displaying... -
Pressure induced softening in ScF3
Recently we have suggested that negative thermal expansion materials will also show an effect called pressure-induced softening, where shown that the elastic stiffness is... -
The quest for the hydrogen-disordered counterpart of ice II
Water displays a highly complex phase diagram that is key to a range of critical processes, from the evolution of icy moons to that of the Earth's hydrosphere and even of life... -
Understanding Deep Earth Mineralogy: A High P/T study of CaSiO3 Perovskite
CaSiO3 perovskite is the third most abundant mineral in the Earth's lower mantle; it also occurs as a major phase at lower pressures and temperatures in subduction zones, where,... -
A High pressure investigation of the Manganese Carbonyls Mn(CO)5(CH3) and Mn(...
Organometallic compounds play an important role in catalysis, and compounds with metal carbonyl groups have been studied at elevated pressure by vibrational spectroscopy, but... -
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... -
Structural analysis of honeycomb iridate alpha-Li2IrO3 under pressure
We propose to perform neutron diffraction measurements on a honeycomb iridium oxide alpha-Li2IrO3 under pressure. Honeycomb iridates have been intensively studied as a possible... -
