A single-crystal diffuse scattering study of Ferrocene
We propose here a detailed study of the diffuse scattering of ferrocene with the key objective of investigating the origin of the cyclopentadienyl (Cp) ring disorder in this... -
The structure and thermoelastic properties of jadeite, NaAlSi2O6, above room ...
Jadeite, NaAlSi2O6, is a rare, but geologically important clinopyroxene. In the upper part of the transition zone between the upper and lower mantle most pyroxenes are... -
Environmental Apatites
Materials adopting the apatite structure are gaining an increasing importance as potential solid-oxide fuel cell electrolytes and for the chemical stabilisation of high level... -
Competition between C-H---O hydrogen bonds and C=O----Br halogen bonds
Our main objective in this proposal is to study the competition between halogen and hydrogen bonding as a function of temperature in the complex (CH3)2C=O--- Br2. The results of... -
An investigation into water incorporation in titanium and phosphate doped A2S...
The drive for increasing energy efficiency and reducing greenhouse gas emissions has garnered increasing support for the use of fuel cell technology, which offers the potential... -
Understanding the formation of diamonds: Calibrating the coesite solid-inclus...
Diamonds provide our only direct samples of the very deep Earth and understanding their origin is consequently of great interest to Earth Scientists. The origin of diamonds can... -
Proton ordering and hydrogen bonding in the hydrous zinc phosphate hopeite, Z...
We request 4 days of beamtime on SXD in order to locate the protons and quantify their ordering within the structure of hopeite Zn3(PO4)2.4H2O. Hopeite is an important phase in... -

Commissioning of High Temerature Furnace
The maximum operating temperature of standard ISIS furnaces with vanadium elements and shields is limited to 1000C (1100C under exceptional circumstances). The ultra... -
High pressure studies of the gillespite-structured phase Ba0.5Sr0.5CuSi4O10
We propose to study the pressure-dependence of the crystal structure of the alkaline earth copper phyllo-decaoxotetrasilicate Ba0.5Sr0.5CuSi4O10 to compliment our earlier... -
The effect of redox on the substitution mechanism of Ti in meteoritic hibonite
We request 3 days of beam-time on HRPD to identify the substitution mechanism of Ti3+ and Ti4+ in synthetic hibonites [CaAl12O19]. The experiment forms part of a larger... -
Total Scattering Study of Caesium and Thallium Azides
This proposal seeks to conduct total-scattering studies on thallium and caesium azides to investigate the effect of temperature on the atomic motions, particularly of the azide... -
Copy of: Structural and Magnetic Studies of Mixed-Valence Iron Silicates
We propose to study the temperature evolution of the spontaneous strain, crystal and magnetic structure of the charge ordered, mixed valence iron silicate ilvaite. In addition,... -
The possibility of strongly ferromagnetic austenite in a stainless steel
It is generally accepted that austenitic steels (fcc) show no ferromagnetic signature. However, thermomagnetic measurements suggest an unexpected ferromagnetic transition (Tc =... -
High resolution structures of the simple halogen bonded complexes.
We propose a high-resolution powder neutron diffraction study of the archetypal donor-acceptor complexes (CD3)3N...I2; (CD3)3N...ICl; C5D5N¿ICl; and C5D5N¿IBr. These are the... -
Investigation of the low temperature phases of SrSnO3
The present proposal is to examine the low temperature structural properties of SrSnO3 using the HRPD. This work aims to examine the structural basis for the unusual low... -
Does elastic twinning play a role in the thermal expansion behaviour of polyc...
We request two days of beam-time on POLARIS to obtain high resolution measurements of the thermal expansion of dolomite [CaMg(CO3)2]. The experiment forms part of a larger... -
Neutron analysis of the structure of SrAl2O4 from 300 to 1273 K.
SrAl2O4 is a stuffed tridymite that has attracted a good deal of interest, since doping with Eu2+ leads to a material with elastic-luminescent response. The structure and phase... -
Thermal expansion and simultaneous Raman spectroscopy of methanol ammoniates,...
We have recently determined the structures of methanol-monoammoniate, and Me-hemiammoniate from neutron powder data. These are found to have different degrees of C-H...O...
