Search for the Structural Origin of the Intermediate Phase
The object of this experiment is to search for the structural origin of the intermediate phase by making careful measurements of the structure of glassy Ge-Se which is a... -
Low-Temperature Structural Phase Transitions in GeV4S8
The defect thiospinel, GeV4S8 adopts a cubic structure at room temperature (space group F-43m). We have identified a new monoclinic phase of this material at 2K, which may be... -
In-situ Specific Heat Measurements and Order Disorder Phase Transition Studie...
We request 4 days on HRPD to perform combined specific heat and neutron powder diffraction measurements of C60 and the molecular hydrogen storage materials, ammonia borane and... -
Metal and Core Phase composition of Renaissance bronzes.
We propose a continuation of the determine the bronze composition of the different parts of three Renaissance Bronzes. These bronzes are of mutiple parts which have been joined... -
Can we use the H-H stretch of adsorbed dihydrogen to characterise materials?
The use of the J 0-to-1 rotational transition of dihydrogen has been extensively used to characterise the state if hydrogen in and on materials. The disadvantage of studying the... -
Structure and Phase Transitions of XNbOP2O7, with X = ND4 and Rb
In this proposal we request 3 days of beam time on HRPD to study the structure and phase transitions of XNbOP2O7 (X = Rb and ND4). These materials have been shown to undergo... -
Phase separation of poly(ethylene glycol) and of poly(propylene glycol) in mi...
Phase behaviour studies have identified hydrogen bonding as a key aspect in polymer solubility in fluorinated liquids, both in terms of solute-solvent and solute-solute... -
Phase separation of hydrocarbon-fluorocarbon surfactants at the air/water int...
Off-specular neutron reflection beamtime is requested to study phase separation at the air/water interface. Stability of systems, such as polymers, is a major area of interest... -
Inherent damage tolerance of fine grained nuclear graphite at elevated temper...
Current UK reactors use a graphite composite material in the core and this material comprises coarse grains and about 20 vol.% porosity. This material functions well so far but... -
Magnetic Phase Diagram of Geometrically Frustrated SrHo2O4
In SrHo2O4, the Ho3+ ions are arranged in a network of triangles and hexagons, and coupled with antiferromagnetic exchange interactions, this gives rise to geometric... -
The Definitive Sodium Niobate Phase Diagram?
NaNbO3 has long been regarded as the 'most complex' perovskite known, with at least seven different phases reported as a function of T, at least two of which have evaded all... -
Further investigation of the methanol to gasoline reaction over ZSM-5 using INS
The reaction of methanol to form hydrocarbons over zeolite catalysts is an important option for conversion of natural gas or coal to liquid fuels. We have shown previously... -
Phase separation and dewetting of dPS/PVME thin films by specular and off-spe...
We will perform time resolved TOF-reflectivity measurements on deuterated polystyrene (PS) and poly(vinyl methyl ether) (PVME) thin blend films, which has a LCST type phase...
