Study of structural and phase transitions of carbon dioxide confined in the n...
The properties of fluids confined in nanopores differ from the bulk mainly due to the solid-fluid interactions and the finite pore size. Such phenomena are of fundamental... -
Determination of the relative magnitudes of static and dynamic displacements ...
The width of a peak in a pair distribution function (PDF) provides a measure of the variation in the distance between a pair of atoms. This results from a combination of thermal... -
Low temperature studies of glycerol and aqueous glycerol
Glycerol, a sugar alcohol with three hydroxyl groups, is a rich and complex system for the study of hydrogen bonded fluids and has been the subject of long-standing scientific... -
Total scattering study of the II to I phase transition in pyridine
Atomistic characterisation of phase transitions in organic materials is important because of the role played by polymorphism in pharmaceuticals and agochemicals. Conventional... -
Ion Exchange and Dehydration in Clinoptilolite
Determination of the position of hydrogen in inorganic materials such as zeolites, coordination compounds, H2 storage materials, energy materials, organometallics etc is a... -
Crystallization of clathrate hydrates from amorphous THF-water solutions
Understanding clathrate hydrate formation and stability is an urgent issue due to their environmental importance. However, a fundamental understanding of the molecular processes... -
Liquid-liquid immiscibility and glass transitions in aqueous solutions
The microscopic structure of a dilute solution of LiCl in water is determined at different thermodynamic states in both the liquid and glassy phases. This solution exhibits... -

Determination of the H-H bond lenght of H2/CuBTC MOF (SANDALS)
The rotational line of hydrogen is very clearly measured with TOSCA. For the past few years I have noticed that the changes in the position of the rotational line do not follow... -
INS studies of Nafion and model compounds
In the archetypal hydrogenoxygen proton exchange membrane fuel cell design, a proton-conducting polymer membrane (typically Nafion) contains the electrolyte solution that... -
Study of the dynamics of a multi-component polymer blend using neutron polari...
Dynamics of multicomponent mixtures such as polymer blends are typically studied with QENS and deuterium labelling. Difficulties arise in the data analysis if the coherent... -
Low Temperature Magnetic, Thermoelastic and Structural Behaviour of Antiferro...
We propose to study the low temperature structural and magnetic changes in three clinopyroxene phases FeGeO3, CaNiSi2O6 and CaCoSi2O6. All three phases order... -
Low-temperature structures of Prussian blue analogues for electrochemical app...
We propose a low-temperature diffraction study at POLARIS of Prussian blue analogues (PBAs) of general formula NaxMM'(CN)6, where 1 < x 2. These systems currently attract... -
Thermodynamic Control of Isotopic Polymorphism
Co-crystals of 4-methylpyridine and pentachlorophenol (MP-PCP) exhibit the very unusual property of isotopic polymorphism, formation of different phases by samples differing... -
Magnetoelectric coupling in the polycrystalline ceramic BiFeO3 - PbTiO3
There are a number of room temperature multiferroics based on BiFeO3. The BiFeO3 - PbTiO3 (BFPT) system shows ferroelectric and antiferromagnetic ordering at room temperature... -
Crystal Structures and Spin Order in CoV2O6 Polymorphs
One-dimensional magnetic materials have been widely studied due to their often remarkable ground states and excitations. Recent study of the triclinic form of CoV2O6 brannerite... -
Structural characterization of water confined in MCM-41
By combining NDIS experiment and EPSR simulation we have been able to show with a previous experiment (RB 720500) two main phenomena for water confined in the MCM silica matrix.... -
The Structure of Ca- and Yb-ammonia Solutions: Polarons, Bipolarons and Elect...
In this experiment we propose to perform diffraction on isotopically substituted samples of Ca/Yb:ND/H3 and Ca/Yb:15ND3 at two concentrations (8 and 2 MPM) using the new NIMROD... -
Structural origin of negative thermal expansion in ScF3
Scandium fluoride has recently been identified as a very simple example of a material showing negative thermal expansion over a wide range of temperatures. In particular, it... -
The Effect of Electron-Phonon Coupling on the Nuclear Dynamics of Superconduc...
We request beam time on VESUVIO spectrometer in order to characterise the effect of electron-phonon coupling on the nuclear dynamics of superconductors. This proposal is...
