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...
