The tetragonal chemically-ordered L10 FeNi phase has recently attracted significant attention for advanced permanent magnet applications due to its compelling magnetic...

Our previous work on sulfuric acid tetrahydrate (SAT) identified a monoclinic high-pressure polymorph, which forms at 5.35 kbar when the tetragonal low-pressure phase is warmed...

We propose a high-pressure powder neutron diffraction study of the archetypal donor-acceptor complexes (CD3)3N...I2 and (CD3)3N...ICl . These are the simplest structurally...

One key to the famous and remarkable photovoltaic properties of methylammonium lead iodide is its structural flexibility. This flexibility can be characterised by testing the...

Of all the stable elements hydrogen(deuterium) is the least well studied from a structural point of view. Not one of its crystal structures has been fully charecterised. This...

Considerable work has been carried out at ISIS with the aim of studying muoniated radicals in the gas phase by RF techniques. This has been motivated both by a desire to...

In recent high pressure experiments (S. Klotz et al., Nature Materials, DOI 10.1038/ NMAT2422, 23.4.2009) we discovered a salt hydrate based on a high-pressure ice form, i.e....

The objective of this experiment is to characterise four particular high-pressure polymorphs of various hydrates discovered by us in recent years during work carried out using...

This beamtime request is part of a long term project based on the liquids diffractometer SANDALS and aimed at developing the use of Paris-Edinburgh press for liquids and in...

Magnetic equiatomic alloys (MEAs) of the general formula MM'X (M, M' = transition metals, X = Si, Ge, Sn) undergo martensitic transition on cooling from high temperature....

Very recently, we have studied the crystalline structure of the C0-phase H2-filled ice (recovered at room pressure and low temperature) and ice XVII, a new form of ice...

Lead scandium niobate (PSN) belongs to the class of perovskite-type relaxor ferroelectrics, which are among the key functional materials. Due to their structural complexity, the...

Zirconium-based metal-organic frameworks (MOFs) are topical nanoporous hybrid materials with tremendous potential for structural versatility and physico-chemical tuneability....

In our daily life, we are aware that liquid and its vapour can coexist. As we increase the temperature and pressure, however, there is a point called the critical point where...

TMAO is a naturally occurring protecting osmolyte which stabilizes proteins and influences intermolecular interactions. Like some other osmolytes it counteracts the effects of...

We propose to study the structure of liquid CO2 by neutron diffraction under high pressure and high temperatures to 6 GPa / 800 K. Carbon dioxide belongs to the most fundamental...

Our recent high (P,T) developments at PEARL beamline will allow us to study the kinetic and thermodynamic behavior of boron 11B under pressures up to 12 GPa and temperatures up...

High pressure is a powerful thermodynamic tool, like temperature, to vary the properties and structure of materials. X-ray and neutron diffraction can be used to measure certain...

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...

The discovery of superconductivity in iron-pnictide materials has generated much excitement in the past year about possibly unifying mechanisms for high-temperature...
