Neutron Total Scattering of Crystalline 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.... -
Investigating the INVAR behaviour of Pd3Fe
INVAR behaviour is the property of having zero thermal expansion over a given temperature range; something very important for certain engineering applications, and very... -
The hypersensitivity of the water phase diagram to ammonium fluoride doping
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... -

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... -
Exploration of the pressure-induced amorphization and glassy states of THF-cl...
Clathrate hydrates (CHs) are ice structures in which water molecules (host) form cages through hydrogen bonds. The cages can accommodate various types of molecules (guests),... -
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... -
Pressure dependence of the crystal structure of the strongly correlated bilay...
Ruthenium-oxides are important strongly correlated electron systems: the bilayer ruthenate Sr3Ru2O7 shows field-induced electronic order, while single-layer Sr2RuO4 is an exotic... -
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... -
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... -
A high pressure diffraction study of the formation of symmetric hydrogen bond...
The imidazole ring is important in both biologically important molecules and materials chemistry. That imidazole derivatives can function in such diverse roles is due in part to... -
Pressure-temperature phase diagram of of the Jahn-Teller transition in LaMnO3
The parent compound LaMnO3 of the hole-doped colossal magnetoresistance materials La1-xAxMnO3 (A = Ca, Sr, Ba etc.) has attracted much interest from condensed matter scientists.... -
The structure evolution of C6F6-C6D6 under high pressure
Pressure induced polymerization of simple molecules is evidenced to be a novel method to construct functional carbon materials. Recently, by controlling the decompression rate,... -
The pressure dependence of the decomposition temperature of methane hydrate i...
The properties of methane ammonia water mixtures are crucial for models of how the outer planets evolved and yet have not been much studied. This proposal is for beamtime to... -
Understanding the structure-propagated compression and decompression of zeoli...
Zeolites are incredibly useful porous aluminosilicate materials. We use them both domestically (pool water purification, washing powders, pet litter, odor removal, water... -
Thermodynamics of Non-Uniform Compression in H-Bonded Molecular Solids
Equations of state (EoSs) show how the thermodynamic variables of temperature, pressure and volume are inter-related. The ideal gas law, PV = nRT, is an example of an EoS which... -
Pressure-Tuning Interactions in Spin-Crossover Metal-Organic Frameworks
The magnetism of spin-crossover (SCO) materials containing Fe(II) can be switched by changing conditions. The low-spin state existing at low temperature or high pressure can be... -
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... -
A high pressure study of the novel hybrid improper ferroelectric HgMn7O12
We have recently discovered how a novel type of hybrid improper ferroelectricity can arise in the perovskite HgMn3Mn412. This ferroelectricity is driven by a highly unusual...
