Magnetic structure determination of PrMn7O12 polymorphs
The AA'$3$Mn$_4$O${12}$ family of manganites with quadruple perovskite structure has recently attracted a lot of interest as a disorder-free model system for many of the... -
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... -

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... -
LOW DIMENSIONAL NETWORKS UNDER PRESSURE. IN-SITU DIFFRACTION MEASUREMENTS OF ...
Carbonate liquids are characterised by low temperature and low viscosity and play an important role in molten carbonate fuel cells, battery electrolytes and, surprisingly, in... -
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... -
Pressure-driven transformation of the Al coordination environment in oxide glass
In situ high-pressure neutron diffraction will be used to investigate the pressure-induced transformation of the Al coordination environment in a prototypical aluminosilicate... -
Density-driven structural transformations in magnesium silicate glass
The density-driven structural transformations in the magnesium silicate glass MgSiO3 will be investigated at pressures increasing to 17.5 GPa. This glass is one of a family of... -
Pressure-induced changes in intermediate range order in the candidate polyamo...
This proposal is a continued exploration of the non-recoverable changes that have been reported in the structure of vitreous SiO2 when compressed. This proposed experiment will... -
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... -
Mechanism of network collapse in strong network glass forming systems
The object of this proposal is to investigate the mechanism of network collapse in the ¿strong¿ network glass forming system GeO2 in the pressure range between 9 and 16 GPa... -

Neutron diffraction at high pressure on alkali diborate glass
Borate glasses are archetypal amorphous oxide characterized by important medium range organisation. These glasses exhibit pressure-induced boron coordination change. The... -
High pressure structural study of BaD2
Simple hydrides are of scientific interest due to their suitability for storage of hydrogen in the solid state. These materials also display a wealth of interesting physics,... -
Comparison of the Compression Behaviour of BaSnO3 and Ba0.575Sr0.425SnO3
We propose to study the effect of pressure on the structure of the tetragonal Ba0.575Sr0.425SnO3, The behaviour will be compared to the compression of the cubic BaSnO3 (parent... -
