Fractal approach to ac impedance spectroscopy studies of ceramic materials
(2001-11-01)
A novel fractal model for grain boundary regions of ceramic materials was developed. The model considers laterally inhomogeneous distribution of charge carriers in the vicinity of grain boundaries as the main cause of the ...
EIS characterisation of Ti anodic oxide porous films formed using modulated potential
(Elsevier Science SaLausanneSuíça, 2007)
Electrochemical impedance spectroscopy as a tool to estimate thickness in PB films
(Elsevier B.V., 2006-03-01)
The analysis of the faradaic impedance of electroactive films provides a characteristic point from which it is possible to estimate the thickness of thin films. Thus, electrochemical impedance spectroscopy was used in this ...

Oxidative dissolution of chalcopyrite by Acidithiobacillus ferrooxidans analyzed by electrochemical impedance spectroscopy and atomic force microscopy
(Elsevier B.V., 2004-08-01)
The microbiological leaching of chalcopyrite (CuFeS2) is of great interest because of its potential application to many CuFeS2-rich ore materials. However, the efficiency of the microbiological process is very limited ...
Notes and reflections on impedance spectroscopy
(Pharmaceutica Analytica Acta, 2017-04-18)
According to the fundamental theory, the interaction ofelectromagnetic field with matter is well described by Maxwell’sequations [1]. The thing is, if we disturb the matter applying analternant potential difference through ...
Influence of PZT insertion on Portland cement curing process and piezoelectric properties of 0–3 cement-based composites by impedance spectroscopy
(2020-03-30)
0–3 Cement-based piezoelectric composites were produced. It was verified that not only the piezoelectric properties of the composites, but also the influence of piezoelectric phase in the cement paste curing process. The ...
Electrochemical impedance sensors for monitoring trace amounts of NO3 in selected growing media
(2015-07-21)
With the advent of smart cities and big data, precision agriculture allows the feeding of sensor data into online databases for continuous crop monitoring, production optimization, and data storage. This paper describes a ...
