Electrochemical Impedance Spectroscopy

2005
Non-steady-state measuring techniques are known to be extremely suitable for the investigation of the electrode kinetics of more complex electrochemical systems. Perturbation of the electrochemical system leads to a shift of the steady state. The rate at which it proceeds to a new steady state depends on characteristic parameters (reaction rate ...

Electrochemical impedance spectroscopy of polyalkylterthiophenes

Electrochimica Acta, 1999
The Electrochemical Impedance Spectroscopy investigation of two isomer polyalkylterthiophenes, namely poly-3′4′- and 33″-didodecylterthiophene was carried out at different stages of polymers oxidation. In the potential range 0.4⩽E⩽0.7 V vs Ag/AgNO3 the ionic resistance Rion associated with the insertion in the polymer structure of the doping species PF−

Electrochemical impedance spectroscopy characterization of beverages

Food Chemistry, 2020
This paper compares the results of standard chemical analytical processes and electrochemical impedance spectroscopy (EIS) in the characterization of different beverages, namely ground coffee, soluble coffee, coffee substitutes, barley, cow milk, vegetable drinks, tea, plant infusions and plant mixtures. For the two approaches, the similarities between
