The quest for the hydrogen-disordered counterpart of ice II
Water displays a highly complex phase diagram that is key to a range of critical processes, from the evolution of icy moons to that of the Earth's hydrosphere and even of life... -
High pressure behaviour of ammonium carbonate monohydrate
A number of compounds crystallise in the NH3-H2O-CO2 ternary system, including ammonium carbonates and carbamates, these being closely related to the water-deficient compound... -
Rotational dynamics in the ferroelectric and giant barocaloric (NH4)2SO4
Barocaloric materials, in which a large isothermal entropy change is associated with a pressure induced phase transition, offer an alternative to vapour-compression technologies... -
Dynamics of proteins undergoing cold denaturation
Pressure as a variable in biophysics/biochemistry allow the structure/function and dynamics/function relationships to be analysed in detail in various biomolecular assemblies.... -
Search for new hydrogen, helium and neon hydrates at high pressure
This proposal is for time to search for predicted gas hydrates at high pressure. The results will provide insight into the factors governing the stability of the H-bonded... -
Compression of meridianiite (MgSO4.11D2O) single crystals to 5 kbar
We propose to carry out single crystal diffraction measurements of the most hydrated MgSO4 compounds, meridianiite, using a thin-walled TiZr gas cell on SXD up to 5 kbar. These... -
Structure of High Density and Low Density solid water
The hypothetical connection between liquid water and the two liquid phases: Low Density Liquid (LDL) and High Density Liquid (HDL) has been difficult to prove experimentally... -
Neutron scattering investigation of the influence of high hydrostatic pressur...
Amyloid fibrils are highly organized filamentous structures formed by the self-assembly of polypeptides. This proposal is to study the effect of pressure on the structure of... -
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... -
Pressure-induced phase transition in methylammonium lead iodide
One key to the famous and remarkable photovoltaic properties of methylammonium lead iodide is its structural flexibility. This flexibility can be characterised by testing the... -
The Ability of Trimethylamine N-Oxide to Resist Pressure Induced Structural P...
Trimethylamine N-Oxide (TMAO) is thought to have the extraordinary ability of allowing organisms to adapt to extreme environments of high pressure, the most famous example being... -
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),... -

Equation of state and phase transitions of the cubic NTE material Cd(CN)2
Despite being the material showing the largest isotropic NTE, Cd(CN)2 is remarkably little studied, particularly compared to isostructural Zn(CN)2 and the canonical NTE material... -
Studying the helimagnetic order and precursor phenomena in MnSi under pressure
The archetype chiral system MnSi belongs to the family of non-centrosymmetric cubic helimagnets where a helimagnetic ordering exists below the critical temperature of 29 K. This... -
Experimental validation of solid hydrogen phases in porous materials via neut...
Metallic hydrogen has long been theorised to be a close-to-room temperature superconductor, but is only predicted to form at GPa pressures. Instead of using extremely high... -
The pressure response of the new superconductor LiFeAs
We will probe the response of the 18K superconductor LiFeAa to pressures of up to 2 GPa in order to investigate the evolution of the crystal structure. In particular we wish to... -
Crystal structure and thermal expansion of acetylene (C2D2)
Acetylene is produced in great abundance in the solar system wherever carbonaceous solids are exposed to energetic radiation. It has been the subject of several studies,... -
Thermoelastic properties of ammonium sulfate, (ND4)2SO4, and the P-T dependen...
Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crysta. There are outstanding... -
Copy of: The Effect of Pressure on the Crystal Structure Titanium Tetrachloride
At ambient pressure and temperature TiCl4 is a fuming yellow liquid. On cooling it forma a solid composed of essentially isolated tetrahedral molecules; the same structure is...
