Microwave dielectric ceramics are used in communications devices. Such materials need high relative permittivity, high dielectric quality factor and be temperature stable....

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...

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...

One fundamental issue in the iron-based superconductors is whether the conventional local moment Heisenberg model is sufficient to describe magnetism in these materials, or...

The recent interest in carbon-based materials like graphene stimulated a deeper analysis of the magnetism in graphite defects. In a previous µSR experiment we observed an...

Hydrotalcites are anionic clays which have a variety of applications, including use as environmentally friendly catalysts and catalyst precursors. In this experiment we propose...

Apatites are a large group of chemically and structurally flexible functional materials with important applications as solid electrolytes. The majority of known apatite...

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...

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...

To determine the temperature dependence of the structures of new mixed and ionic conducting materials in the n = 2 ruddlesden-popper,mellilite and pyrochlore systems.
