Constant-Phase-Element Behavior Caused by Coupled Resistivity and Permittivity Distributions in Films [PDF]
, 2011 A recent proposed model showed that the impedance of a film with a uniform permittivity and a resistivity that varies along its thickness according to a power-law is in the form of a constant phase element (CPE). This model is further considered in order

Substances with zero static permittivity
Scientific Reports, 2022 AbstractThe structure of materials with a negative electric susceptibility has been determined. Their electrical properties correspond to vanishing static dielectric permittivity. We give a theoretical explanation of anomalous polarization of powders observed in experiments and the mechanism of emergence in an aerosol cloud of an electric field, which ...

Advanced Functional Materials, EarlyView.Phase‐separated alkyl poly(vinylimidazolium) membranes exhibit exceptional ionic conductivity, counter‐ion selectivity, and proton‐blocking ability by forming stable micro/macrophase‐separated domains. This design overcomes the conductivity–selectivity trade‐off in conventional ion‐exchange membranes (IEMs), offering a new paradigm for high‐performance
