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... -
Exploring Structural and Spin Orders in the Quantum Spin Liquid Candidate Znx...
Quantum spin liquids (QSLs) are intriguing states of matter in which magnetic frustration and strong quantum fluctuations prevent classical long-range magnetic order. To date,... -
Determination of the magnetic field-temperature phase diagram in metal-organi...
Metal-organic magnets are of interest primarily due to the synthetic versatility enabled by the vast array of organic complexes which can be used to coordinate magnetic ions and... -
Spin excitations in La2CoO4
We will use MAPS to measure the complete spin excitation spectrum of the quasi-two-dimensional S=3/2 antiferromagnet La2CoO4. The measurement is motivated by recent observations... -

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... -
Kinetics of Molecular Intercalation into Graphite Oxide
The search for new porous materials is increasingly be driven by socio-economic pressure to diversify our energy supply and minimize environmental impact. Carbon-based... -
Structural and magnetic characterisation of polar magnetic perovskite-based m...
A new generation of low-power high-density information storage would be enabled by the development of ?multiferroic? materials which function at or above room temperature. Such... -
Confined water in a geo-polymer system
The main objective of this proposal is to investigate the dynamics of ultra-confined water in the slits pores of geological cavities (mineral tobermorite). This system provides... -
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... -
Thermal expansion of kyanite, andalusite and sillimanite
Al2SiO5 forms three naturally-occurring polymorphs, kyanite, andalusite and sillimanite. These minerals are produced by varying degrees of metamorphism of sedimentary rocks, the... -
Strain effect on the magnetic ground state of the ferroelectric Ca3CoMnO6 system
The search for new ferroelectric materials, where the ferroelectricity results from magnetic frustration, has been a topic of great interest to the condensed matter physics... -
Structure and magnetism in Sr2IrO4 - benefits of 193Ir use
We plan to investigate the use of the isotope 193Ir for studies of magnetism in iridium containing materials using Sr2IrO4 as a test case. This isotope is important for neutron... -
Dynamics of Poly Dimethyl Amino Ethyl Methacrylate / water glycerol mixtures
We want to study the microscopic mechanisms of solvent dynamics such as water and glycerol in ahydrophilic polymer. Dielectric measurements suggest that below the glass... -
Exploration of the microscopic origins of thermal anomalies observed in molec...
It is a well established fact that several molecular liquids experiences a series of thermal anomalies as measured by microscopic and macroscopic techniques. A remarkable case... -
Understanding quantum and classical proton transfer mechanisms in protic ioni...
Considerable research efforts have been devoted to polymer electrolyte membranes fuel cells. It has been recently proposed as a promising approach to replace aqueous... -
