High pressure charge and magnetic transitions in PbCrO3
The high pressure perovskite PbCrO3 has been known since the 1960s but the electronic properties were controversial. The average structure is a cubic Pm-3m perovskite but a... -
Pressure-induced phase transitions in methylammonium lead iodide
Methylammonium lead iodide has recently been recognised as an excellent photovoltaic material, with energy conversion efficient of over 20% with the prospect of gaining higher... -
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... -
High pressure polymorphism in ammonium bicarbonate, (ND4)DCO3
In an earlier high-pressure survey of the P,T phase diagram of deuterated ammonium carbonate, we observed changes in the neutron powder diffraction patterns that are consistent... -
High-pressure structure of magnetite nanoparticles
One way in which nanoparticles may differ from bulk properties are in terms of their response to pressure, but at the present time there have been very few structural studies of... -
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... -
Structural analysis of Kitaev spin liquid candidate beta-Li2IrO3 under pressure
The theoretical predication of Kitaev spin liquid in honeycomb iridates triggered tremendous interests. We recently discovered a new candidate material, beta-Li2IrO3 with a 3D... -
Unravelling the temperature-pressure phase diagram for the multiferroic, BiFeO3
Bismuth ferrite is arguably the most widely studied multiferroic material due to room temperature magnetic and ferroelectric ordering. However, despite extensive research the... -
High Pressure Driven Spin States in LaCoO3
This proposal is concerned with determining variations in the high pressure structure of LaCoO3 and observing changes within this as the material undergoes some well... -
Understanding the Pressure Response in Amines: Weak hydrogen-bonding vs Non-b...
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... -
High Pressure Neutron Diffraction of Croconic Acid
Croconic acid (Cacid) possesses a well-defined hysteresis in polarization at room temp and the highest spontaneous polarization observed in organic ferroelectrics to date. The... -
High-pressure studies of energetic co-crystals
This proposal will explore the effects of elevated pressures and temperatures on the structures of two energetic co-crystals - [CL-20:TNT] and nitroguanidine:nitropyridone.... -

Pressure-induced structural and magnetic transitions in honeycomb ruthenate A...
Honeycomb ruthenates (Ru4+, 4d4) with strong spin-orbit coupling are expected to host unconventional magnetic ground state owing to a spin-orbital-entangled Jeff = 0 state. The... -
Phase evolution in the transition from epsilon to gamma glycine
Glycine, the simplest naturally-occurring amino acid, exhibits unusually extensive phase diversity. Three polymorphs are known under ambient conditions. Each shows different... -
Unravelling the temperature-pressure phase diagram for the multiferroic, BiFeO3
Bismuth ferrite is arguably the most widely studied multiferroic material due to room temperature magnetic and ferroelectric ordering. However, despite extensive research the... -
High-pressure studies of energetic co-crystals and salts
This proposal will explore the effects of elevated pressures and temperatures on the structures of an energetic co-crystal [CL-20:0.5 HMX] and an energetic salt containing... -
Behaviour of hexamethylenetetramine hexahydrate to 5 GPa
The title compound, more succinctly referred to as HMT-hydrate, is a rare example of a water-framework zeolite structure with an organic guest molecule hydrogen bonded to the... -
Pressure Tuning of Sodium Battery Materials: PART II
This is a continuation proposal to the previous study (RB. 1720418) of NaCoO2. Even if the data analysis is still under process, the result could indicate that the transition...
