Vacancy Distribution in Praseodymium Doped Ceria
Doped cerias are currently being used as oxide ion conducting electrolyte materials in solid oxide fuel cells (SOFCs). Depending on the nature and concentration of the dopant... -
Na-Dynamics in Solid Ionic Conductors: 11Al2O3-Na2O and Na2Ti3O7
We propose to measure the quasielastic neutron scattering (QENS) spectra to study the diffusion dynamics in beta- alumina (11Al2O3-Na2O) and Na2Ti3O7. The measurement of QENS... -

A detailed study of the temperature and compositional variation of defect structure in doped bismuth tantalates is proposed. Tantalum doping into Bi2O3 can achieve d-phase... -
Towards intermediate temperature diffusion: oxygen dynamics in Ce(Nb,V)O4+d
CeNbO4+d (0 <= d <= 0.33) displays mixed ionic-electronic conductivity at ~800 °C, where it adopts the tetragonal scheelite structure. Prior research has shown that... -
The structure and thermoelastic properties of jadeite, NaAlSi2O6, above room ...
Jadeite, NaAlSi2O6, is a rare, but geologically important clinopyroxene. In the upper part of the transition zone between the upper and lower mantle most pyroxenes are... -
Superstructure in bismuth rich substituted bismuth oxides
A study of superlattice ordering in substituted bismuth oxides is proposed. Bismuth rich compositions at the 14:1 B:M (where M = W/La and Ta) ratio will be investigated. These... -

QENS studies of hydride ion diffusion in alkaline earth hydrides
We propose to study hydride ion diffusion in AEH2 (AE = Ca and Ba) using the QENS technique. We have recently demonstrated that the charge carrier in these materials are hydride... -
Oxide ion vacancy distribution in A site substituted defect pyrochlores.
Electrolytes based on pyrochlores such as Ln2M2O7 (M = Ti, Zr, Hf) have attracted attention due to their relative stability combined with relatively high ionic conductivity at... -
Copy of: Local magnetic order and the paramagnetic-parmagnetic transition in MnO
The antiferromagnetic-paramagnetic transition in MnO at 118 K occurs at a much lower temperature than anticipated from its Curie-Weiss constant theta~550 K. Consequently, strong... -

Structure-conductivity relationship in La2-xBaxNiO4+d
Unusual total conductivity behaviour at high Ba contents may be attributed to a change in conduction mechanism at high tempertaures, structure change or phase... -
Defect structure in W/Ln and Ta/Ln di-substituted bismuth oxide based solid e...
The stability regime of the oxide ion conductor delta-Bi2O3 is limited to a narrow temperature range just below its melting point. Substitution of Bi3+ by a variety of isovalent... -
