Phonon-Liquid-Electron Crystal Behaviour in Cu8GeSe6
Thermoelectric devices enable the conversion of thermal energy into electrical power. The development of new materials is essential to enable large scale implementation of... -
Cation Ordering in Quaternary Sulphides and Selenides
We wish to investigate quaternary chalcogenides, A2ZnBQ4 (where A = Cu, Ag; B = Ge, Sn; Q = S, Se). Calculations indicate stannite (S) or kesterite (K) superstructures of both... -
Development of a Novel Low - Intermediate Temperature Solid Proton Conductor
The compound, Si5O(PO4)6, is a component of a solid phosphoric acid catalyst, it has highly unusual coordination of the silicon (octahedral, as well as the more common... -
Phase Transitons and Phonon-Liquid-Electron Crystal Behaviour in Argyrodites
We wish to collect powder neutron diffraction as a function of temperature on four samples of argyrodites, A8GeQ6 (A = Cu, Ag; Q = S, Se), to investigate structural phase... -
Influence of shear on polymer adsorption at solid / liquid interfaces
Lubricants contain a complex mixtures of polymers and base oils that must provide protection to moving surfaces with minimal energy loss due to friction or viscous drag. There... -
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... -
Structural Phase Diagram of the new Multiferroic Hexagonal YbFeO3
This experiment aims to map out the structural phase diagram of the new multiferroic compound hexagonal-YbFeO3 as a function of temperature, both above and below room... -
