Determination of the structure of SiO2-rich aqueous fluids at high temperatur...
Many geological processes are governed by the migration of hot, mineral-rich water. These "hydrothermal" fluids are stable at high pressures and temperatures and are important... -
Incompressibility, crystal structure and Anderson-Grüneisen parameter of orth...
The ambient-pressure Pnma phase of NiSi is a technologically important material used to form contacts in microelectronics. Recently we carried out the first study of NiSi at... -
L-Alanine above 10 GPa
Recently we studied L-alanine to 9.85 GPa. This is the highest pressure for which structural data are available for any organic system larger than methane. The results enabled... -
Relationships between microstructure and deformation mechanisms in a new Ni-b...
Haynes 282 is a novel Ni-base superalloy, combining excellent weldability and general processability with a moderate cost. As such, it is a very promising material for e.g.... -
Transformations in B2O3 glass under pressure
B2O3 is a prototypical glass forming oxide material and is an essential component in many industrial glasses. Unlike SiO2 and GeO2 its structure under ambient conditions is not... -
Pressure-temperature phase diagram of of the Jahn-Teller transition in LaMnO3
The parent compound LaMnO3 of the hole-doped colossal magnetoresistance materials La1-xAxMnO3 (A = Ca, Sr, Ba etc.) has attracted much interest from condensed matter scientists.... -
Density-driven structural transformations in calcium silicate glass
The density-driven structural transformations in the calcium silicate glass CaSiO3 will be investigated at pressures increasing to 17.5 GPa. This glass is one of a family of... -
Towards the Calibration of Chemical Pressure
The application of hydrostatic pressure allows the precise tuning of atomic separations, which control electronic structure and virtually all the interatomic interactions that... -
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... -
Structural Insights into Borohydride-Halide Li-Ion Conductors, LiM(BH4)X (X= ...
Solid state electrolytes are key components to replace volatile liquid electrolytes in lithium-based batteries to deal with the safety concern. We propose here variable... -

The application of hydrostatic pressure allows the precise tuning of atomic separations, which control electronic structure and virtually all the interatomic interactions that... -
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... -
Network compression and pressure-induced amorphisation in Zn(CN)2
Zn(CN)2 is an important material because it shows isotropic NTE over a large temperature range and to an extent more than double that of ZrW2O8. This unusual behaviour... -
Substrate-dependent structure of thin hydrogel films
Hydrogels are water-rich polymer networks made from natural or synthetic polymers, which are widely used in biomaterials, medicine and antifouling. We have developed PEG-based... -
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,... -
Understanding the Earth's Core-Mantle Boundary: Crystal and Magnetic Structur...
The physical properties of the post-perovskite phase of MgSiO3 control the dynamics of the lower thermal boundary layer of the Earth¿s mantle, but many of these properties... -
High-pressure structure of ferrosilite FeSiO3 glass
The density-driven structural transformations in ferrosilite glass FeSiO3 will be investigated at pressures increasing to 17.5 GPa. This glass is one of a family of silicate... -
Insulator to metal transition in TiOCl at high pressures
We propose to study the high temperature structure of TiOCl where a pressure induced metal to insulator transition has been reported recently by Kuntscher et al.Due to our...
