Structural study of BiNiO3 at high pressures and low temperatures
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... -
Pressure-Induced Linkage Isomerism in a Prussian Blue Analogue
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... -
The effect of pressure on the Fe-Fe bond and carbonyl groups in Fe2(CO)9
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... -
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... -
Pressure-induced changes in intermediate range order in the candidate polyamo...
This proposal is a continued exploration of the non-recoverable changes that have been reported in the structure of vitreous SiO2 when compressed. This proposed experiment will... -
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... -
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... -
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... -

Equation of state of ice VI
Ice VI is likely to be a major mantle mineral in the interiors of large icy moons in our solar system, and in large icy extrasolar planets. It is also a common accessory phase... -
The Anderson-Gruneisen parameter and high P/T crystal structure of post-perov...
Recently, our view of the Earth¿s lower mantle changed dramatically. It had been thought that two major phases were present in all the lower mantle: MgSiO3-perovskite (PV) and... -
