Lead free antiferroelectric materials are the focus of much attention for the replacement of lead based materials in electronic devices, such as high energy storage capacitors,...

Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the...

We propose to use the HRPD to establish the sequence of structures, and the nature of the transitions between these, in two complex manganites Sr0.5Pr0.5MnO3 and...

Ge-Sb-Te chalcogenide alloys are important for applications in advanced (non-volatile) random-access memory based on a reversible switching between the crystalline and amorphous...

In recent years, the long-standing belief that beyond the critical point, matter exhibits no clear transition between liquid-like and gas-like states has been questioned. A line...

The physical properties of the perovskite family remain an enduring topic in solid state research. In this proposal we aim to study the solid state structural phase transitions...

Recent theoretical work has identified that oxygen octahedral rotations (OORs) in layered perovskites such as Ruddlesden–Popper (RP) phases A2[A’n-1BnO3n+1] can generate...

Ammonia has been proposed as a high density chemical energy-storage media, which can be safely and reversible stored within low cost saline halides. Here we propose to extend...

Light metal amides and imides are a new class of highly active ammonia decomposition catalysts. Indeed, composites of lithium imide and transition metal nitrides are likely to...

Sr2IrO4 is an important material in the field of condensed matter physics, being a proposed J_eff=1/2 Mott insulator. Recent publications have shown that the reported low- and...

This proposal seeks to study three systems associated with heat-storage applications using in situ neutron powder diffraction. The first experiment will focus on a sample of...

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...

Sr2IrO4 is an important material in condensed matter physics, displaying a novel Jeff=½ Mott insulating state and being a rare comparative system for understanding the high...

This proposal aims to study condensation transitions in nanoporous flexible materials by means of wide Q-range neutron diffraction. We plan to perform an in-situ gas...

Recently [RB 900007], we have demonstrated that it is possible to determine the detailed site-by-site behaviour of hydrogen during in-situ absorption and desorption in metal...

We request 3 days on POLARIS to study the detailed crystal structure of a sodium battery cathode material that is currently under consideration for use in commercial sodium...

Al2SiO5 forms three naturally-occurring polymorphs, kyanite, andalusite and sillimanite. These minerals are produced by varying degrees of metamorphism of sedimentary rocks, the...

We have recently performed a ZF muon experiment on Ba3Dy2GaNb9O30 in EMU under the influence of electric fields and demonstrated that this material demonstrates multiferroic...

HRPD data will be collected in situ at low and high temperatures from perovskites belonging to the Sr(ZrxTi1-x)O3 solid solution which have recently been characterised for their...

Sol-gel derived calcium silicates are of great importance due to their ability to bond to bone and stimulate new bone growth. Diffraction has revealed the atomic-scale changes...
