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... -
The role of defects in the pressure-induced octahedral tilting in Prussian bl...
We propose a high-pressure study of two Prussian blue analogues, Mn[Co(CN)6]0.67 and MnPt(CN)6. Our high-pressure XRD study shows a phase transition from cubic to rhombohedral... -
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... -
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... -
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... -
High-pressure studies of energetic co-crystals and salts
This proposal will explore the effects of elevated pressures and temperatures on the structures of an energetic co-crystal containing nitroguanidine (NQ)and an energetic salt... -
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... -
High pressure behaviour of the cubic NTE material Cd(CN)2
Cubic cadmium(II) cyanide shows the most pronounced isotropic NTE effect known, with behaviour more than twice as extreme as that of better known materials such as ZrW2O8.... -
A High-Pressure Low-Temperature Crystallographic Study of the Pm3m - I4/mcm F...
The perovskite-structured phases and their associated phase transitions remain an enduring topic of study within the solid state sciences due to their importance in both applied... -
Uranium minerals at extreme conditions: a powder neutron diffraction study
As Fukushima and Chernobyl have demonstrated, the consequences of an accident in a nuclear power plant are international. Extreme conditions, far from thermodynamic control are... -
Phase behaviour of methane clathrate under conditions relevant to Titan's int...
Methane clathrates are likely to be an important constituent of icy satellite interiors and a source of methane in the atmosphere of Saturn's giant satellite Titan. There is... -
Structural and Magnetic Behaviour of PrCrO3 at High Pressure
The application of hydrostatic pressure tunes the interatomic separations within a compound, causing changes in the electronic structure. This alters many other material... -
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... -
In Situ neutron diffraction of liquid gallium at elevated pressure
Gallium has a low melting point and forms a liquid just above room temperature. The melting curve has a negative slope and when pressure is applied room pressure phases will... -

Our previous PEARL experiment (RB1810619) on LTL zeolite with fluorinert as a pressure-transmitting fluid contradicts the data we collected using silicon oil as... -
The structure of methane water fluid mixtures at high pressure
We have recently discovered that above 2 GPa in the liquid/fluid forms water and methanebecome miscible in proportions up to 33 mole% of methane. This proposal is for time to... -
Interplay of magnetism and superconductivity in the iron-based spin ladder Ba...
Iron-based superconductors (FeSCs) have been an essential research area in condensed matter physics. Spins of iron sites forming a long periodic configuration, called the... -
