Hydrogen is an efficient energy carrier that can be produced from renewable sources and stored in alloys in solid-state for long period enabling the transition towards CO2-free...

Cr-Mo steel forgings are used in oil and gas components to provide flow control and protection against over-pressure. Joining forgings to flow line requires 2 steps: Dissimilar...

Antiferroelectric materials are attracting extensive attention due to their potential in energy storage applications. These materials exhibit a double polarisation-field...

Skyrmions are topological objects which have been shown to exist in the spin textures of a range of magnetic materials. As we have recently demonstrated in our transverse field...

Thermal batteries find use in applications such as emergency power systems and ejector seats in aircraft. They operate at elevated temperatures of around 400-500 °C, where the...

There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap and safe cathodes. Li2FeSiO4 shows promising performance as a cathode but...

Lipid compositional variation across the cell's membranes as well as asymmetry between two contiguous monolayers in the same membrane are critical for alive and healthy cells....

We have recently observed extraordinary polymorphism on cooling various sodalites under vacuum. Materials undergo a phase transition followed by a fully reversible...

The proposed experiment is to measure texture and strain tensor for specimens made by Direct Laser Deposition (DLD) and Linear Friction Welding (LFW) techniques. The...

Water ice displays a remarkably complex phase diagram containing pairs of hydrogen-ordered / disordered phases. Ice XII is a hydrogen-disordered phase and ice XIV is its...

Below 80 K ordinary water ice (ice Ih) undergoes a phase transition in which the randomly oriented molecules in the crystal adopt an ordered orientation. This ordered form of...

We intend to perform an inelastic neutron scattering experiment on para-H2 adsorbed in L-Isoleucyl-L-valine (IV) microporous systems using the TOSCA spectrometer. IV is one of a...

Ammonium bromide undergoes a pressure-induced order-disorder transition, where the disordered (plastic) phase is thought to consist of a random distribution of ammonium cations...

The perovskite structure with general formula ABX3 describes many hundreds (if not thousands) of materials. Many have interesting and technologically important properties. The...

We are proposing 4 days of beamtime on GEM to conduct the experiment on 10 alloy nanoparticles; PdxRu1-x (x = 0, 0.1, 0.3, 0.5, 0.7, 0.9, 1) and PdRuM (M = Rh, Pt, Ir). We have...

Solar cells based on a layer of halide perovskite have recently seen rapid increases in efficiency, with certified values in excess of 20%. The prototypical material of this...

The increasing global demand for portable energy means that the search for new electrode materials for rechargeable solid-state batteries is an important scientific challenge....

In this proposal we request 3 days of beam time on HRPD to study the structures (both atomic and magnetic) of a variety of oxychalcogenide phases: La2O2Se2Fe2O, Ce2O2Se2Mn and...

Metal-organic perovskites offer many of the advantages of their ceramic analogues, with a range of exploitable functionality including ferroelectricity. Understanding the...

The accurate determination of the defect structure of rare earth (RE) doped ceria solid electrolytes is fundamental for the comprehension of oxygen diffusion and charge...
