High‐temperature dielectric properties and impedance spectroscopy of PbHf 1− x Sn x O 3 ceramics

Thermoelectric properties of LaRh(1-x)Ni(x)O(3).

We report measurements and analyses of resistivity, thermopower and thermal conductivity of polycrystalline samples of perovskite LaRh(1-x)Ni(x)O(3). The thermopower is found to be large at 800 K (185 µV K(-1) for x = 0.3), which is ascribed to the high-temperature stability of the low-spin state of Rh(3+)/Rh(4+) ions. This clearly contrasts with the thermopower of the isostructural oxide LaCoO...

Impedance/Dielectric Spectroscopy of Electroceramics–Part 1: Evaluation of Composite Models for Polycrystalline Ceramics

In the microcrystalline regime, the electrical (impedance/dielectric) behavior of grain boundarycontrolled electroceramics is well described by the “brick-layer model” (BLM). In the nanocrystalline regime, however, grain boundary layers can represent a significant volume fraction of the overall microstructure. Simple boundary-layer models no longer adequately describe the electrical properties ...

Hyperbolicity of the family $f_c(x)=c(x-frac{x^3}{3})$

The aim of this paper is to present a proof of the hyperbolicity of the family $f_c(x)=c(x-frac{x^3}{3}), |c|>3$, on an its invariant subset of $mathbb{R}$.
