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... -
Anion disorder in Ti pyrochlores as a precursor in the transition to fluorite
The aim of this work is to understand the nature of anion disordering in pyrochlore oxides and to establish what, if any, correlations exist between the anion position, disorder... -
The origin of high oxide-ion conductivity and the nature of the intermediate ...
4 days of beam time is requested on HRPD to study the crystal chemistry of the ferroelectric Aurivillius phase Bi4Ti3O12 (Curie Temperature, Tc ~ 675 C, mixed conductor) and a... -
VT studies of the local structure of a fuel cell cathode and lead-free ferroe...
We are about to submit a detailed pair distribution function study of a new lead-free ferroelectric material based on RMC analysis. This method will be applied in VT studies of...
