Polyhedral connectivity in high lead silicate glasses
We have a long-established interest in the structural role of heavy-metal, lone-pair cations such as Pb in glasses. PbO can be incorporated to very high concentrations in oxide... -
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... -
Microstructure of self-assembled polymer nanoparticles in non-polar solvents
Polymerization-induced self-assembly (PISA) is a versatile method that enables the synthesis of diblock copolymer nanoparticles in many solvents. In particular,... -
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... -
Spin-echo encoded neutron refraction of air bubbles in a fibrous protein gel
Calcium caseinate is a promising candidate to be developed into a meat analogue. When the dough like protein gel is subjected to mild shear and heat, it turned into a pronounced... -
Compression mechanisms of LTA and EMT zeolites
We request 4 days to collect high-resolution structural high-pressure data on two zeolites - zeolite A and EMC-2. Our previous theoretical findings from geometric simulation... -
The Effect of Pressure on the Crystal Structure of Serine Hydrate
Serine monohydrate undergoes a phase transition at 5.2 GPa which involves reorientation of water molecules. It appears that this disrupts H-bonding elsewhere in the crystal,... -
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... -

SANS experiments on phase separation in duplex stainless steel
Duplex stainless steels have an attractive combination of high strength and corrosion resistance, making them the natural choice in applications such as e.g. pressurised... -
P4Se3 polyamorphic glasses synthesised at high-pressure
PxSe1-x glasses cover almost entire composition range from pure Se to P0.84Se0.16. In addition, red phosphorus is usually also amorphous. The P4Se3 cage compound, situated in... -
Pressure and Temperature-Induced Phase Transformations in PbZrO3-BiFeO3 Ceramics
The proposed experiment involves identification of the phase boundaries and determination of the crystal structures of PbZrO3-BiFeO3 (PZ-BF) ceramics as a function of... -
Systematic Investigation of Magnetically Doped Toplogical Insulators
Topological insulators (TIs) are of inherent interest as they are conducting on the surface whilst insulating on the bulk. We would like to investigate magnetically doped... -
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... -
The effect of particles on the structure of mucin ¿ understanding the challen...
Progress in the development of nano-sized hybrid therapeutics and nano-sized drug delivery systems - "nanomedicines" - over the last decade has been remarkable. One key... -
Structure of Permanently Densified SiO2 Glass
SiO2 is a prototypical network-forming glass that can be processed under high pressure and temperature conditions to give a permanently densified glass with a density that is up... -
The Pressure and Temperature Dependence of the Structure of Ammonium Triiodide
We have shown that the molecular ionic solids MI3 (M=Tl, Cs, Tl, NH4) undergo structural phase transitions below 3.4 GPa at RT to give the same new high pressure phase (HP) with... -
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).... -
Breaking Zachariasen rules - the structure of barium zirconium fluoride glasses
Glass is an essential material with applications that are dominated by oxides, but fluoride glasses (based on barium zirconium fluorides, "ZBLAN" glasses) have key applications... -
Atomic structure of mercury chalcohalide glasses
Optical applications of chalcogenide glasses need a wide transparency window in far IR. Promising glass systems include HgI2. We have synthesised three vitreous systems...
