High-pressure structure of magnetite nanoparticles
One way in which nanoparticles may differ from bulk properties are in terms of their response to pressure, but at the present time there have been very few structural studies of... -
Nuclear quantum effects and ortho-to-para conversion for hydrogen adsorbed in...
Metal-organic frameworks represent one of the most studied options to store hydrogen for clean-energy applications. Nuclear quantum effects, and in particular zero-point... -
High pressure polymorphism in ammonium bicarbonate, (ND4)DCO3
In an earlier high-pressure survey of the P,T phase diagram of deuterated ammonium carbonate, we observed changes in the neutron powder diffraction patterns that are consistent... -
The high-pressure structures of carbon dioxide hydrate
The gas hydrates offer potential as hydrogen and carbon dioxide storage materials for use either in transport applications or for carbon sequestration. We have discovered a... -
Understanding the mechanism of benzyl alcohol oxidation using supported Au-Pd...
Gold, in its nano-scale, has been found to be very effective catalyst for oxidation reactions. More recently, it was shown that supported Au-Pd catalysts can be used for... -
3D neutron TOF diffraction imaging
We propose to use SXD for mapping the crystallographic phases in an extended 3D benchmark object. The phase distribution will be reconstructed using a geometrical aberration... -

Pressure-induced phase transitions in methylammonium lead iodide
Methylammonium lead iodide has recently been recognised as an excellent photovoltaic material, with energy conversion efficient of over 20% with the prospect of gaining higher... -
High pressure charge and magnetic transitions in PbCrO3
The high pressure perovskite PbCrO3 has been known since the 1960s but the electronic properties were controversial. The average structure is a cubic Pm-3m perovskite but a... -
High Pressure Driven Spin States in LaCoO3
This proposal is concerned with determining variations in the high pressure structure of LaCoO3 and observing changes within this as the material undergoes some well... -
Energy dependent, sample transmission correction for time-of-flight diffracti...
Diffraction from hydrogenous materials is complicated by the large incoherent scattering contribution from hydrogen. For many materials the solution is to deuterate before... -
Thermal equations of state for kyanite, andalusite and sillimanite
The three Al-silicate polymorphs, kyanite, andalusite and sillimanite, are well-known geological markers used to determine the extent of P- and T-induced metamorphism... -
Proton momentum distribution in Phosphoric acid
Phosphoric acid, H3PO4, is a technically important material as the electrolyte in commercial fuel cells because of its high protonic conductivity. The mechanism for the... -
Copy of: Pressure induced phase switching magnetic ordering in BiFeO3-PbTiO3
This experiment seeks to continue previous work on PEARL, whereby the phase is altered in the room temperature multiferroic BiFeO3 - PbTiO3 using hydrostatic pressure with the... -
Pressure effect on structural phase transition in the Kagome antiferromagnet ...
RBaCo4O7 (R = rare earth ion or Y) compositions belong to class of strongly frustrated antiferromagnets. Their crystal structure is build up of alternating Kagome and triangular... -
The pressure response of the new superconductor LiFeAs
We will probe the response of the 18K superconductor LiFeAa to pressures of up to 2 GPa in order to investigate the evolution of the crystal structure. In particular we wish to... -
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... -
Non-uniform elastic deformation of layered crystal structures
The aim of the experiment is to determine the relative compressibility of the structural layers in three 211 MAX phases (Ti2AlC, Ta2AlC and Cr2AlC) using the PEARL-HiPr beam... -
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... -
A high-pressure study of monovalent bifluorides
This proposal seeks PEARL beam time to conduct the first high-pressure neutron diffraction study of the monovalent azides XDF2, where X = Na, ND4, Cs and Tl. In so doing, we...
