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...

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...

We wish to determine a structure we have observed in a dodecane/surfactant/water system. Initial experimentation has suggested the possibility of spontaneous formation of a...

Bottlebrush polymers, backbone with long side chains, are very interesting regarding their architecture, which is different from well known linear polymers. Not only the...

Ruthenate perovskites have a diverse range of electronic properties originating from electron-electron correlations within broad 4d bands. We have recently investigated the high...

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...

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...

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...

We propose an investigation in which the crystal structure of Fe2(CO)9 will be studied as a function of pressure. This compound has previously been investigated by high pressure...

The Prussian blue analogue K0.4Fe4[Cr(CN)6]2.8.16H2O (1) is a soft ferromagnet at ambient pressure with a critical temperature (Tc) of 19 K. Bridging cyanides are oriented in...

BiNiO3, synthesized at high pressure, has the unusual charge distribution Bi3+0.5Bi5+0.5Ni2+O3 with ordering of Bi3+ and Bi5+ charges on the A sites of a highly distorted...

We have shown using previous experiments that moderate hydrostatic pressures can be used to switch phase from tetragonal to rhombohedral in the material BiFeO3 - PbTiO3 at room...

The functionality of biological membranes is closely tied to their structural behavior. To understand this behavior we propose to study the conformality of artificial lipid...

The application of hydrostatic pressure allows the precise tuning of atomic separations, which control electronic structure and virtually all the interatomic interactions that...

We propose a high-pressure neutron powder diffraction study of three halogen-bonded complexes, namely trimethylamine:ICl, 1,4-dioxane:(IBr)2 and pyridine:IBr. These are some of...

We propose to use neutron scattering to determine the Al-O distances in aluminosilicate and aluminoborate glasses, an information that can only be given by scattering...

We wish to use elastic (this experiment) and inelastic neutron scattering (experiments on MARI and MERLIN submitted in this round) as an approach to quantify the change in...

Recently, our view of the Earth¿s lower mantle changed dramatically. It had been thought that two major phases were present throughout all of the lower mantle:...

The aims of this proposal are to explore the high-pressure, high-temperature behaviour of 3 important energetic materials - FOX-7, CL-20, and ADN. These experiments are expected...

Our previous HRPD experiment on the Pd-D2 system resolved the long-standing controversy over the occupation of T interstitial sites by D, showing that T sites are occupied owing...
