Evolution of the structure of the Li/ND3 intercalate of FeSe with pressure
This experiment follows our ambient pressure characterisation of the Li intercalate of FeSe which is a superconductor with a Tc of 43 K. Li atoms, amide ions and ammonia... -
Density-driven structural transformations in boro-germanate glass
The resistance of glass to fracture is crucial for its use as a structural material in fields ranging from engineering to architecture. Here, B2O3 can play a crucial role in... -
The high pressure structure of cobalt-bearing silicate glasses
The aim of this proposal is to examine the pressure induced changes in the structure of two cobalt-bearing silicate glasses. Transition metals such as cobalt can adopt different... -
Exploration of the pressure-induced amorphization and glassy states of THF-cl...
Clathrate hydrates (CHs) are ice structures in which water molecules (host) form cages through hydrogen bonds. The cages can accommodate various types of molecules (guests),... -
Investigation of new phase, MnBi2, by in situ high-pressure neutron diffraction
Permanent magnets are essential for renewable energy technologies such as electric cars and wind turbines. Global demand for magnets is increasing, however, the elements used to... -
Investigation of the interactions of perfluoroalkyl substances with model wor...
Perfluoroalkyl substances (PFASs) are fully fluorinated, stabile, and surface-active compounds. They contain both a hydrophobic fluorinated carbon chain and an ionizable... -
The pressure dependence of the decomposition temperature of methane hydrate i...
The properties of methane ammonia water mixtures are crucial for models of how the outer planets evolved and yet have not been much studied. This proposal is for beamtime to... -
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... -
Behaviour of hexamethylenetetramine hexahydrate to 5 GPa
