Compressibility and Tilting of Polyhedra within Sr2NiMoO6 at High Pressure
Ordered double perovskites (also known as elpasolites) have the general formula A2BBO6 where A is generally a rare earth metal or alkaline earth metal and where B and B are... -
Equation of state and phase transitions of the cubic NTE material Cd(CN)2
Despite being the material showing the largest isotropic NTE, Cd(CN)2 is remarkably little studied, particularly compared to isostructural Zn(CN)2 and the canonical NTE material... -
Thermal expansion of hexa-halogenated benzenes: C6Cl6, C6Br6, C6I6.
The aim of the present proposal is to complete a systematic study on the effects of isotopic and chemical substitution on the thermal expansion and vibrational properties of... -
Structure and cation ordering in A2Sn3Q7-type phases (A=In, Cr; Q= S, Se)
We wish to exploit the contrast afforded by neutrons to study the ordering of In and Sn cations in indium tin chalcogenides. Cation ordering has been inferred from spectroscopic... -
The magnetic excitation spectrum in Fe1.07Te
We propose to investigate the high energy magnetic spectrum in Fe1.07Te. We have previously investigated the fluctuations in Fe1.14Te in the incommensurate phase and have found... -
Surface adsorption of lipopeptides: interfacial layer structure
Lipopeptide surfactants are highly effective at reducing interfacial tension. However, there is a general lack of understanding of the relationship between their molecular... -
Phase diagram of a switchable dielectric framework near the critical point
The family of hybrid Prussian blue analogues includes many electroactive materials, where organic cations moving within the pores of the cyanide framework cause unusual and... -

A high-temperature neutron powder determination of the phase transition and c...
Cu2ZnSnS4 (CZTS) is a solar cell material of great interest. However the material when fabricated, although of high symmetry, contains substantial defect concentration and a... -
INS STUDY OF BIOCHAR AS SOLID ACID CATALYSTS
Pyrolysis is considered as a sustainable way to generate energy from bio-oil, however, biochar – a solid residue by-product– is inevitably produced in the production line. We... -
Phase behaviour and dielectric phenomena in bismuth niobate energy storage ma...
Bismuth niobate (BiNbO4) is widely used in multilayer RF and microwave components such as capacitors and chip layer capacitors. This compound exhibits two main structural forms... -
Investigation of phosphatidylcholine and its interaction with 1,2 propandiol ...
The aim of the present study is to use neutron diffraction enhanced with isotopic substitution and subsequent computer simulations to determine the head group solvation of a... -
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... -
Tracking spring-type motions in inorganic helices
Materials with helical and double helical structure motifs are prone to display fascinating spring-type behaviour, i.e. a shallow energy surface along the spring-axis in which... -
Charged surfactant adsorption and detergency upon reconstituted plant cuticul...
A number of studies have determined that non-ionic surfactants are capable of altering diffusionrates and transportation of both water and active ingredients thorough the waxy... -
Correlated local structure distortions in the family of high-temperature supe...
This proposal follows from a short previous test experiment (RB 920345) aimed at understanding the nature of local structure distortions in YBa2Cu3O6.9 and their possible role... -
Possible amorphous:amorphous phase separation in bioactive glass containing s...
There is an interest in understanding the nature of fluoro-alumino-silicate glasses based upon the apatite stoichiometric composition and of potential within ionomer cements for... -
Tilting transition and dimensionality crossover of anion chain order in Ba1-x...
Transition metal oxynitride perovskites are an emerging class of functional materials. However, their oxide/nitride ordering principles were unclear until a recent study of the... -
Hourglass dispersion in overdoped manganites
Overdoped manganites were recently shown to exhibit stripe-like ordering of charges orbitals and magnetic moments. The magnetic excitations in these materials show close... -
Roles of magnetic anisotropy and inter site exchange interactions in the temp...
NdMnO3 exhibits A-type antiferromagnetism with TN =73 K. At 15 K, Nd sublattice orders with a (0, -Fy, 0) type ferromagnetic arrangement. Mn spin reorientation from (Ax, Fy, 0)...
