Using the electrochemical impedance spectroscopy to characterize carbon steel in biodiesel medium
(2012-12-01)
Electrochemical impedance spectroscopy measurements using two carbon steel electrodes in soybean biodiesel medium, produced by methylic route, were performed in an electrochemical cell that allows positioning the two ...
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 ...
