Ferroelectric materials, in which the polarization may be switched, are an important class of compounds due to their academic and technological relevance. The mechanisms that...

Methylamines are an ideal chemical system to study in order to understand the effects of steric bulk and competing non-bonding interactions on hydrogen bonding at the networks...

SnSe has recently been reported to have very good thermoelectric performance. This is linked to an ultralow thermal conductivity and occurs in the B-phase (ZT > 2 above 800...

The aim of the proposal is to investigate changes in the crystal structure of A-site disordered La0.5Ba0.5CoO3-d; and layered LnBaCo2O6-d; (Ln = La, Y) perovskites at...

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...

The use of the J 0-to-1 rotational transition of dihydrogen has been extensively used to characterise the state if hydrogen in and on materials. The disadvantage of studying the...

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...

When synthesised at high pressure and temperature, holmium germanate adopts the pyrochlorestructure. Because of its geometry, materials with this structure often have exotic and...

Bi4Ti3O12 is a well-known and studied layered perovskite; such phases are ferroelectrics, which have been used in random-acccess memories and other applications. Understanding...

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

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...

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...

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 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...

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...

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...

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...

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...

Multiferroic materials which exhibit both ferroelectric and (anti)ferromagnetic ordering are of great technological importance offering the potential for the design of novel...

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...
