Local ordering in the pressure-induced order-disorder transition in ammonium ...
Ammonium bromide undergoes a pressure-induced order-disorder transition, where the disordered (plastic) phase is thought to consist of a random distribution of ammonium cations... -
The icy-moon analogue of MgSiO3-perovskite: MgSO4.9H2O a high-pressure study
Mg-sulfate 11-hydrate (meridianiite) is decomposed by pressure to form Mg-sulfate 9-hydrate + ice, a process that will occur in the mantles of large icy planetary bodies and... -
Magnetic properties of graphene
Magnetic properties of graphitic compounds are of current interest for both theoretical and experimental research in the fields of condensed matter physics and magnetism. In the... -
A High pressure investigation of the Binary carbonyls of group 7 M2(CO)10 M =...
The structures of two binary metal carbonyls containing a metal-metal bond Mn2(CO)10 and Re2(CO)10 will be studied as a function of pressure. Both these molecules undergo a... -
High pressure charge transitions in PbCoO3
PbCoO3 used to be the missing link in the PbMO3 perovskite series. PbCoO3 was recently synthesized by the Azuma group using high-pressure synthesis at 12 GPa. NPD at JPARC... -
SANS contrast measurements on important protein/DNA interactions from RCaH
This proposal is to perform SANS contrast measurements on three protein/DNA interactions currently worked on at the Research Complex at Harwell. This is part of an ongoing... -
Diffraction 'artifacts' due to shape, size and thickness variation in copper,...
In relation to TOF flight neutrondiffraction experiments conducted on Renaissance sculpture, we are proposing a systematic study of controlled shape, size and thickness effects... -
Neutron diffraction of amorphous magnesium carbonate (AMC)
Biominerals, including calcium carbonates, are found in a range of organisms. Although amorphous calcium carbonate (ACC) is inherently unstable, it is a key material in... -
High Pressure Thermoelastic Properties of Thermoelectric PbSe
We propose to study the effect of pressure and temperature on the crystal structure and the elasticproperties of lead selenide, an important material for conversion of waste... -
Molecular cluster of citric acid in water solution
Citric acid is not only a molecule of fundamental importance for cell respiration but also used in multiple and varied industrial applications including food industry and... -
Local structure of polymers in confined geometries in surface dominated samples
This proposal is focused on developing an understanding of how surfaces affect the local structure of synthetic polymers. There is considerable evidence for a strong variation... -
Copy of: Interactions between Diatrizoic acid and water in pre-nucleation clu...
The formation of water containing crystal forms, so-called hydrates, is a real problem for the pharmaceutical industry. Hydrates show thermodynamically the lowest solubility in... -
High-pressure structure of magnetite nanoparticles
One way in which nanoparticles may differ from bulk properties are in terms of their response to pressure, but at the present time there have been very few structural studies of... -
Understanding enhanced thermoelectric properties of sodium cobaltate doped by...
The thermoelectric power factor for (Na1-y¿My¿)0.8CoO2 is dramatically increased when M = Sr, but it is essentally unchanged from the pure compound when M = Ca. Our previous SXD... -

Alloxan - a high density organic under pressure
Organic molecular crystal structures have densities that are typically in the range 1.2-1.4 gcm-3 although these can be increased, in general, to ca. 2.0 GPa through application... -
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.... -
Structure of water subjected to a static electric field
The behavior of liquid water under an electric field is a crucial phenomenon in science and engineering. However, its detailed description at a microscopic level is still far... -
Degenerate ground-states in Ho2-xYxSn2O7
Ho2-xYxSn2O7 is characterized by degenerate magnetic ground-states, which involve the magnetic structure for x->0 (Spin-Ice phase) and the two-fold degeneracy of the... -
Examining the properties of water channel in an organic matrix.
The objectives are to study the interaction of water molecules held in a channel in an organic matrix. We have structurally characterised a water tetramethylpiperididine complex...
