According to the impedance spectroscopy data, a significant frequency dispersion of real and imaginary components permittivity was found in intercalated Ag x HfS 2 samples. Using modular formalism, dielectric relaxation times were determined, which decrease magnitude with an increase silver content Their coincidence determined from dependences parts complex shown. Keywords: Intercalates, impeda...

For understanding the operation of perovskite solar cells and light-emitting diodes, knowledge dielectric properties is indispensable. The perovskites are frequency dependent due to presence moving ions, which complicates interpretation impedance spectra. Using Au/CsPbI2Br/Au capacitors with varied layer thickness as a model system, we demonstrate that in dark, an extended Maxwell circuit consi...

Dielectric spectroscopy can be used to determine the dipole moment of colloidal particles from which important interfacial electrokinetic properties, for instance their zeta potential, can be deduced. Unfortunately, dielectric spectroscopy measurements are hampered by electrode polarization (EP). In this article, we review several procedures to compensate for this effect. First EP in electrolyt...

This paper presents a novel approach to estimate the soil ionic concentration by way of multi-frequency impedance measurements and using the quasi-static dielectric mixing models to infer the various ionic concentrations. In our approach, the permittivity of the soil dielectric mixture is measured using impedance spectroscopy and the results are used as input parameters to dielectric mixing mod...

Non–destructive testing methods constitute a fast growing field of study that concerns various materials. In addition to the up today bibliography a novel technique is presented here.
