Study of ordered silicon connectivity defects in the novel zeolite ITQ-45
The structure of the novel pure silica zeolite ITQ-45 has been recently determined in our laboratory. However, although it appears to be a fully connected framework, 29Si NMR... -
Determination of the Low Temperature Crystal Structure of Cobalt Adipate
This experiment will use high resolution neutron diffraction to investigate the crystal and magnetic structure of the cobalt adipate framework, Co(CO2(CH2)4CO2), at lower... -
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... -
Correlation of structure and magnetic ordering with composition in layered co...
We propose to use HRPD to determine the detailed structures of a series of cobalt oxysulfides containing Co in square planar coordination. Two compositions Sr2CoO2Cu2-deltaS2... -
The nature of the Ferroelectric Phase in CdTiO3
The aim of the present proposal is to establish the structure of the ferroelectric phase of CdTiO3 and to determine the nature of the ferroelectric-paraelectric phase... -
Investigating the presence of an order-disorder transition in La6Y4Ge6O27
Apatite-type phases have been attracting interest as a new class of oxide ion conductors, and in these systems, the key defects are oxide ion interstitials. We have recently... -
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... -
Structural Studies of BiFeO3-KNbO3 Solid Solution
Both BiFeO3 and KNbO3 are technologically important materials. BiFeO3 exhibs room temperature magnetic and ferroelectric ordering whilst KNbO3 is a lead free ferroelectric.... -

The high temperature phases of multiferroic YMnO3
Hexagonal YMnO3 is a well-studied, but poorly understood, multiferroic material, which adopts the 'geometric' mechanism of ferroelectric distortion, rather than the more normal... -
Nuclear Structures of Lithium Substituted Layered Transition Metal Oxide Cath...
Novel cathode materials for rechargeable batteries have been under intense investigation since high cost and toxicity of current Li-ion batteries. We propose to study the... -
Crystal structure and thermal expansion of acetylene (C2D2)
Acetylene is produced in great abundance in the solar system wherever carbonaceous solids are exposed to energetic radiation. It has been the subject of several studies,... -
Powder Diffraction Study of Ion Exchanged AV-7
The aim of this study is to elucidate the crystal structures of a series of microporous tin silicate materials after different degrees of ion exchange with strontium. The... -
From giant magneto-elastic coupling to negative thermal expansion
We recently used high-resolution neutron diffraction on HRPD to observe the largest magneto-elastic coupling ever seen in a metallic magnet. The material studied was CoMnSi, a... -
In-situ high-resolution study of the Pd-D2 system after passage over the ther...
Our previous HRPD experiment on the Pd-D2 system resolved the long-standing controversy over the occupation of T interstitial sites by D, showing that T sites are occupied owing... -
Thermoelastic properties of ammonium sulfate, (ND4)2SO4, and the P-T dependen...
Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crysta. There are outstanding... -
Structural Studies of Li(ND3)n11BD4
On exposure to ammonia, Li(11)BD4 forms the ammoniate Li(11)BD4(ND3)n. Our recent experiment (RB820252) has shown that there are four distinct crystalline phases in the... -
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...
