This review presents a wide-ranging broad-brush picture of dielectric relaxation in solids,
making use of the existence of auniversality'of dielectric response regardless of a wide …

We review pioneering and recent studies of the conductivity of solid state systems at
terahertz frequencies. A variety of theoretical formalisms that describe the terahertz …

This research focuses on the synthesis of nanoscale cobalt spinel ferrite (CoFe 2 O 4) via
the sol-gel auto-combustion method and its integration with polyvinylidene fluoride (PVDF) …

Over the past two decades percolation theory has been used to explain and model a wide
variety of phenomena that are of industrial and scientific importance. Examples include …

The striking similarity of ac conduction in quite different disordered solids is discussed in
terms of experimental results, modeling, and computer simulations. After giving an overview …

A number of basic scientific questions relating to ion conduction in homogeneously
disordered solids are discussed. The questions deal with how to define the mobile ion …

A scaling approach in the conductivity formalism is applied to lithium tellurite glasses of
different compositions. We observe that the hop** frequency can be used as the scaling …

A molecular-level understanding of dynamics in imidazolium-based ionomers with different
counterions and side chain lengths was investigated using X-ray scattering, oscillatory …

A review of the current state of understanding of dielectric mixture properties, and
approaches to use numerical calculations for their modeling are presented. It is shown that …

Abstract In a recent Letter, Roling et al.[Phys. Rev. Lett. 78, 2160 (1997)] proposed a novel
scaling approach, requiring no arbitrary parameters, for the analysis of the ac conductivity …
