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... -
Polycarbonate and tetramethyl bisphenol A polycarbonate
The miscibility of polycarbonates (PC) with polystyrene (PS) appears to be closely related to chain dynamics. Among all polycarbonates, tetramethyl bisphenol-A polycarbonate... -
Structures and magnetism of chemical and electrochemical deintercalates of la...
We propose to use POLARIS to perform two related experiments. Firstly we will investigate the structures and compositions of derivatives of some layered Mn/Cu oxysulfides which... -
Competing degenrate magnetic states in Ba1-xNaxFe2As2
Magnetic and superconducting ground states have been proposed to coexist in a relatively narrow compositional range in the so-called 122 pnictide superconductors. We recently... -

What is the Room Temperature Structure of NaTaO3?
The current proposal seeks to establish the origin of t non-perovskite-like peak splitting observed in HRPD data for NaTaO3. It is our hypothesis that this is a result of the... -

Hydrogen Uptake by Pillared Graphite Oxides
High sorption capacities and enhanced interaction strengths are the two most fundamental prerequisites for the deployment of carbon-based materials as hydrogen-storage media. In... -
The Dynamics of Molecular Hydrogen in Synthetic Clays
In this proposal we aim to study the low temperature uptake and dynamics of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual... -
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... -
Magnetic structure of layered oxide chalcogenides: Ba2CoO2Cu2Te2 and Sr2CoO3CuSe
This is an experiment to measure the crystal structures and the thermal evolution of the magnetic structures of two new layered oxide chalcogenides. In Ba2CoO2Cu2Te2 we will... -
Uptake of Molecular Hydrogen by High-performance Carbon Nanostructures (IRIS)
High sorption capacities and enhanced interaction strengths are the two most fundamental prerequisites for the deployment of carbon-based materials as hydrogen-storage media. In... -
Structural Studies of PbZr1-xTixO3: completing the puzzle in the tetragonal a...
We request 6 days of HRPD time in order to study the structures on the tetragonal side of the lead zirconate-titanate (PZT) phase diagram, a region that has so far been rather... -
The intermediate stages of hydrogen disorder to order phase transitions in ice
In recent years, our team has discovered three new phases of ice: ices XIII, XIV and XV. On the basis of calorimetric data and some limited diffraction data collected on GEM we... -
Magnetic ordering in new multi-anion solids: Sr2Fe3Se2O3 and Sr2Cr3As2O2
We have identified new multi-anion solids with transition metals in unusual coordination environments and with apparently complex magnetic ordering. This experiment proposed for... -
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... -
