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... -
Understanding the structure-propagated compression and decompression of zeoli...
Zeolites are incredibly useful porous aluminosilicate materials. We use them both domestically (pool water purification, washing powders, pet litter, odor removal, water... -
Late antique copper-alloys from Faragola, San Giusto and Canusium (Puglia, It...
From the archaeometric point of view, very few studies have been performed on late antiquecopper-alloys, mainly by means of destructive techniques.The present study opens up... -
High pressure phase transition in copper guanadinium formate
The family of guanidinium metal formates has the perovskite structure and, like many perovskites, is of interest for these materials' magnetic and electric properties, in... -
The structure evolution of C6F6-C6D6 under high pressure
Pressure induced polymerization of simple molecules is evidenced to be a novel method to construct functional carbon materials. Recently, by controlling the decompression rate,... -
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... -
Pressure-temperature phase diagram of of the Jahn-Teller transition in LaMnO3
The parent compound LaMnO3 of the hole-doped colossal magnetoresistance materials La1-xAxMnO3 (A = Ca, Sr, Ba etc.) has attracted much interest from condensed matter scientists.... -
Combined Neutron Resonance Spectroscopy and Deep Inelastic Neutron Scattering...
We request 5 days on VESUVIO in order to examine the sensitivity of 87Sr (n,) resonances and DINS to the metal-insulator and liquid-solid transitions in the Sr-NH3... -
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... -
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 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... -
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 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... -
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... -
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... -
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),... -
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... -
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... -
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 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...
