Impedance and dielectric spectroscopy revisited: Distinguishing localized relaxation from long-range conductivity
TL;DR: In this paper, the advantages of plotting a.c. data in terms of impedance, electric modulus, and dissipation factor simultaneously are illustrated, and the degree to which these assignments may be made is related to the dielectric relaxation ratio ( r = ϵ s ϵ ∞ ) and the differences between the time constants of the different relaxation processes present in the material being examined.

Lattice Parameters, Ionic Conductivities, and Solubility Limits in Fluorite-Structure MO2 Oxide [M = Hf4+, Zr4+, Ce4+, Th4+, U4+] Solid Solutions
TL;DR: In this article, a generalized relationship between dopant size and ionic conductivity in binary systems of MO2 oxides was shown, illustrating that the smaller the difference between the dopant ionic radius and the critical dopant radius, the higher the conductivity.

Oxide-ion electrolytes
TL;DR: The performance of the oxide-ion electrolyte of a solid oxide fuel cell (SOFC) is critical to the development of an intermediate-temperature system as discussed by the authors, and there remains a strong motivation to search for new, improved oxide ion electrolytes.
