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... -
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... -
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... -
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... -
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... -
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... -
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... -
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.... -
High-Pressure Investigation of the Ferroelectric ND4IO3
We propose a high-pressure neutron powder diffraction study of the crystal structure of deuterated ammonium iodate, ND4IO3, which is known to undergo a ferroelectric phase... -
High-pressure studies of energetic materials
This proposal seeks to identify and characterise high-pressure polymorphs of the energetic materials hydroxylammonium perchlorate, CL-20, diaminodinitroethene (FOX-7), and... -
High-pressure and high-temperature studies of N-guanylurea dinitramide (FOX-1...
The aims of this proposal are to explore the high-pressure, high-temperature behaviour of 2 important energetic materials - N-guanylurea dinitramide (FOX-12) and... -
Round Robin on TOF Texture Analysis
In view of advances in texture research at pulsed neutron sources, we propose that ISIS participates in a 'Texture Round Robin' to benchmark the existing texture analysis... -
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),... -
Pressure dependence of the crystal structure of the strongly correlated bilay...
Ruthenium-oxides are important strongly correlated electron systems: the bilayer ruthenate Sr3Ru2O7 shows field-induced electronic order, while single-layer Sr2RuO4 is an exotic... -
Effect of pressure-transmitting medium on the phase transformation of para-am...
The pressure-transmitting medium in a high-pressure experiment is usually thought of as an inert medium that allows the sample to be compresses rather than crushed. In organic... -
High-pressure studies of inorganic azides
This proposal seeks to identify and structurally characterise the high-pressure phases of the azide salts of sodium, silver, lead, and the ammonium ion. Azides are examples of... -
Enhancing isotope analysis and localization by combining neutron resonance tr...
Neutron resonance transmission (NRT) and prompt gamma activation analysis (PGAA) are nuclear techniques for isotope analysis based on the measurement of the transmitted neutron... -
High-pressure and variable-temperature studies of RDX
Previous studies have suggested that a high-pressure form of the widely used secondary explosive RDX can be obtained above ~4 GPa and 488 K. This phase is reported to be... -
A High pressure investigation of the Manganese Carbonyls Mn(CO)5(CH3) and Mn(...
Organometallic compounds play an important role in catalysis, and compounds with metal carbonyl groups have been studied at elevated pressure by vibrational spectroscopy, but... -
High Pressure studies of BiMO3 perovskites
Bismuth based perovskites have been shown display many interesting properties. The field of A site bismuth perovskites gained renewed vigour due to the recent demonstration of...
