High pressure phase diagram of water-methanol mixtures.
Alcohol-water mixtures are well known to possess a number of thermodynamic and transport properties that deviate from those of an ideal binary mixture. While the structure of... -
The structure of dense fluid deuterium
It is partly due to quantum effects that hydrogen (and deuterium) exhibits a dramatic compressibility: in its fluid state, prior to freezing at room temperature at 5.5 GPa, it... -

The hydrogen clathrates of urea
The search for new hydrogen storage materials is of considerable importance given the need to develop a carbon-free energy economy. This proposal is to investigate the urea-... -
Formation and Structural Properties of Non-Stoichiometric Molybdenum Hydride
There is significant renewed interest in the super-conductivity of hydrogen-rich materials ever since the reported superconductivity of H2S at 203 K . As a result there is... -
Structure of hot dense liquid carbon dioxide
We propose to study the structure of liquid CO2 by neutron diffraction under high pressure and high temperatures to 6 GPa / 800 K. Carbon dioxide belongs to the most fundamental... -
Recrystallisation of LiCl-doped ice under pressure
In recent high pressure experiments (S. Klotz et al., Nature Materials, DOI 10.1038/ NMAT2422, 23.4.2009) we discovered a salt hydrate based on a high-pressure ice form, i.e.... -
The high pressure structure of deuterium
Of all the stable elements hydrogen(deuterium) is the least well studied from a structural point of view. Not one of its crystal structures has been fully charecterised. This... -

The hydrogen clathrates of hydroquinone and urea
The search for new hydrogen storage materials is of considerable importance given the need to develop a carbon-free energy economy. This proposal is to investigate the... -
Magnetic and crystal structure of goethite FeOOD under pressure
We propose the first high P/T neutron diffraction measurements on goethite (FeOOH), both the ambient pressure alpha- as well as the high-pressure epsilon-phase, in the P/T range... -

Volume isotope effect in recovered ice VIII
Water is the most fundamental hydrogen-bonded compound on Earth and its physical properties are essential for research areas ranging from live sciences to planetology. In this... -
High-p/T setup and Anvil Material Testing
We request 6 days commissioning time be allocated on PEARL for the on-line testing of new high-p/T furnace setups and new anvil materials. -

Concerted proton tunnelling in ordinary ice
In a recent study we showed, by incoherent elastic and quasielastic neutron scattering measurements, the existence of non-harmonic motion of hydrogen in ordinary ice. The motion... -
Search for NaCl-ices under high pressure
We recently discovered that substantial amounts of LiCl can be built homogeneously into the ice VII structure when the glassy LiCl:6D2O is annealed under high pressure. We...
