Electrochemical issues in impedance tomography [PDF]

open access: yesChemical Engineering Journal, 2000
Linear ramp cyclic voltammetry and ac impedance spectroscopy have been used to investigate the electroactivity of Zeneca products and filtration solvents using platinum microelectrodes. Linear ramp cyclic voltammetry has been used to establish appropriate excitation potentials which will minimise electrochemical reactions associated with the product or

Impedance of electrochemically modified graphite. [PDF]

open access: yesActa chimica Slovenica, 2014
Electrochemical impedance spectroscopy, EIS, has been applied for characterization of electrochemically modified graphite electrodes in the sulphuric acid solution. Graphite modifications were performed by potential cyclization between potentials of graphite oxide formation/reduction, different number of cycles, and prolonged reduction steps after ...

Sythesis of High Voltage Supercapacitor and Electrochemical Performance

open access: yesInternational Journal of Electrochemical Science, 2013
The work unit for 100 V voltage of the hybrid supercapacitor is synthesized by using Ta/Ta2O5 as the anode, activated carbon as the cathode. Compared with the usual electrochemical capacitor working voltage, the capacitance had improved.
