Proton dynamics in novel organic ferroelectric materials
The vast majority of known ferroelectrics are inorganic compounds such as barium titanate and potassium dihydrogen phosphate. Contrary to naïve expectation, ferroelectricity in... -
Multiferroic (Ferroelastic/Magnetic) Phase Transitions in KMnF3
KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling... -
The Dynamics of Paraquat in Aqueous Solution and Hydrated Clay
This proposal will enable us to study the dynamics of an important water soluble pesticide molecule, paraquat, in solution and in the interlayer region of swelling... -
A Self-consistent Description of the Thermoelastic Properties of Dielectric P...
20 years ago, Anderson proposed that the thermoelastic properties of the dominant (mantle) phase within the Earth, MgSiO3 perovskite, could be described as a simple Debye solid.... -
Magnetic structure of pyrochlore irridate Y2Ir2O7
We propose to study by powder neutron diffraction the ordered magnetic state of the pyrochlore compound Y2Ir2O7. There is currently an increasing interest in the condensed... -

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... -
Well, well, well: the free energy landscape of hydrogenated La(Fe,Si)13?
Magnetic cooling promises efficiency savings at room temperature but requires rapid cycling of a magnetic refrigerant in a magnetic field. Refrigerants with first order... -
The Dynamics of Water in Hydrous Micas
The study of the interaction mechanisms between water and layered silicates is central to the evaluation of the physicochemical properties of these materials, and it is an... -
The role of Disorder in Phase Transitions in some manganese Perovskites
The aim of this work is to understand the origin of the difference in the behaviour between the two doped manganites Sr0.65Pr0.35MnO3 and Sr0.70Ce0.30MnO3. The hypothesis we... -
Electronically-driven structural transition in Ti-doped Ca3Ru2O7
The purpose of the experiment is to determine the effect of titanium doping on the structural and magnetic transitions of Ca3Ru2O7. The pure material undergoes a Néel transition... -
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... -
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... -
QENS studies of Na-ion battery materials
LixCoO2 is used extensively in portable batteries in laptops and mobile phones, but the scarcity of Li means that alternative materials are required. Structurally related... -

Melting point dynamics of Confined fluids
This proposal aims to investigate the dynamics of the melting transition in H2O and CO2 when confined in a vycor (SiO2) matrix. The field of fluids in confined geometries is... -
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...
