A High-pressure Study of the Crystal Structures of CsDF2, ND4DF2 & TlDF2
This proposal seeks PEARL and HRPD beam time to study the pressure and temperature dependence of the crystal structures of deuterated caesium, ammonium and thallium bifluoride.... -
Neutron diffraction study of the casting technology of antique bronze coins
Neutron tomography data on high-Pb antique bronze coins indicated that two different copper alloy phases are formed during the casting process. We propose to use GEM for... -
High-pressure studies of methyl stearate
In order to tackle emissions targets for CO2, there is increasing pressure to replace fossil fuels with renewable fuels. Biodiesel is one such renewable transportation fuel that... -
Characterising new high-pressure phases of ammonia monohydrate
Over the past two years I have carried out high-pressure surveys of the ammonia monohydrate (AMH) phase diagram using a Paris-Edinburgh press mounted on the D20 beam-line at the... -
Compositional and microstructural analysis of iron meteorites through time of...
Iron meteorites consist overwhelmingly of nickel-iron alloys. The metal taken from these meteorites is known as meteoric iron and was one of the earliest sources of usable iron... -
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... -
High pressure behaviour of sulfuric acid tetrahydrate
Our previous work on sulfuric acid tetrahydrate (SAT) identified a monoclinic high-pressure polymorph, which forms at 5.35 kbar when the tetragonal low-pressure phase is warmed... -
A high pressure structural study of the charge transfer complexes trimethylam...
We propose a high-pressure powder neutron diffraction study of the archetypal donor-acceptor complexes (CD3)3N...I2 and (CD3)3N...ICl . These are the simplest structurally... -
PTM dependant polymorphism of acrylamide
Our recent X-ray and single crystal studies have shown that acrylamide can undergo different phase transformations depending on the pressure transmitting medium used i.e.... -
High-pressure, high-temperature studies of energetic materials - RDX and HMX
One of the aims of this proposal is to quench to ambient pressure a metastable form of the widely used secondary explosive RDX. This is formed above ~4.5 GPa and 448 K but is... -
Investigating the INVAR behaviour of Pd3Fe
INVAR behaviour is the property of having zero thermal expansion over a given temperature range; something very important for certain engineering applications, and very... -
High-pressure powder neutron diffraction study in Pd2MnIn
Intermetallic ternary full Heuslers have potential spintronic applications, due to a possible link between the mechanisms for magnetism and half-metallicity in these systems.... -
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... -

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.... -
Investigation of maleic-d2 acid isomerization at high pressure
Experiments performed in our laboratory indicate that maleic acid undergoes an unexpected structural change when subject to high pressure and temperature conditions. For these... -
Investigation of the pressure dependence of the negative area expansion mater...
We will investigate the structure of 4-chloroimidazole a material, which undergoes extreme anisotropic thermal expansion,.as a function of pressure at a range of temperatures... -
Understanding pressure-driven structural and magnetic properties in LaFeO3
This proposal is concerned with determining variations in the high pressure crystallographic and magnetic structure of LaFeO3. LaFeO3 is a characteristic example of... -
High Pressure Driven Spin States in LaCoO3
This proposal is concerned with determining variations in the high pressure structure of LaCoO3 and observing changes within this as the material undergoes some well...
