The role of defects in the pressure-induced octahedral tilting in Prussian bl...
We propose a high-pressure study of two Prussian blue analogues, Mn[Co(CN)6]0.67 and MnPt(CN)6. Our high-pressure XRD study shows a phase transition from cubic to rhombohedral... -
Interplay of magnetism and superconductivity in the iron-based spin ladder Ba...
Iron-based superconductors (FeSCs) have been an essential research area in condensed matter physics. Spins of iron sites forming a long periodic configuration, called the... -
Exploration of the pressure-induced amorphization and glassy states of THF-cl...
Clathrate hydrates (CHs) are ice structures in which water molecules (host) form cages through hydrogen bonds. The cages can accommodate various types of molecules (guests),... -
Understanding the structure-propagated compression and decompression of zeoli...
Zeolites are incredibly useful porous aluminosilicate materials. We use them both domestically (pool water purification, washing powders, pet litter, odor removal, water... -
Alloxan - a high density organic under pressure
Organic molecular crystal structures have densities that are typically in the range 1.2-1.4 gcm-3 although these can be increased, in general, to ca. 2.0 GPa through application... -
High-pressure studies of insenitive explosives: 2,4-dinitroanisole (DNAN) and...
The aims of this proposal are to explore the high-pressure, high-temperature behaviour of 2 important energetic materials - 2,4-dinitroanisole (DNAN) and nitrotriazalone (NTO).... -
New high pressure hydrates for energy applications.
The need to decarbon the energy economy is one of the greatest technological challenges mankind has ever faced. Gas hydrates offer new clean potential materials for hydrogen... -
Uranyl carbonates under pressure
The recommended method for storage of spent nuclear fuels is in an underground repository for 100,000 years. Under the long timescales, containment will fail and radioactive... -
Understanding enhanced thermoelectric properties of sodium cobaltate doped by...
The thermoelectric power factor for (Na1-y¿My¿)0.8CoO2 is dramatically increased when M = Sr, but it is essentally unchanged from the pure compound when M = Ca. Our previous SXD... -
Structure of a 2D antiferromagnet under pressure
Magnetic superexchange is strongly dependant on the degree of orbital overlap and hence the interatomic distances and angles within a structure. One way of tuning magnetic... -
The role of step-size on the pressure phase diagram of BiFeO3
bismuth ferrite (BFO) remains the most studied multiferroic as a result of room temperature electric and magnetic ordering. However, real world applications are limited due to... -
High pressure structural studies of halogen bonded systems
We propose a high-pressure neutron powder diffraction study of three halogen-bonded complexes, namely trimethylamine:ICl, 1,4-dioxane:(IBr)2 and pyridine:IBr. These are some of... -
A High-Pressure investigation on 3,4,5-Trinitropyrazole
This proposal will explore the effect of elevated pressure on the 3,4,5-Trinitropyrazole (TNP). TNP releases a large amount of dinitrogen gas as a detonation product which is... -
UNDER PRESSURE: an alternative route to novel zeolite catalysts
Zeolites are microporous aluminosilicate minerals which are characterised by their highly crystalline framework structures. Having distinct porosity, zeolites are used in a... -
Compressibility and Tilting of Polyhedra within Sr2NiMoO6 at High Pressure
Ordered double perovskites (also known as elpasolites) have the general formula A2BBO6 where A is generally a rare earth metal or alkaline earth metal and where B and B are...
