The Apparent Constant-Phase-Element Behavior of a Disk Electrode with Faradaic Reactions [PDF]

open access: yes, 2007
Geometry-induced current and potential distributions modify the global impedance response of a disk electrode subject to faradaic reactions. The problem was treated for both linear and Tafel kinetic regimes.

Differential analysis of dynamic immittance spectra

open access: yesElectrochemistry Communications, 2020
This work presents a new approach to the analysis of immittance spectrograms of systems characterised by non-stationarity. The possibility of linking the evolution of the immittance response with changes in the parameters describing the system is ...

Delaminated areas beneath organic coating: A local electrochemical impedance approach [PDF]

open access: yes, 2006
Local electrochemical impedance mapping was used to investigate delamination phenomena at the steel/epoxy-vinyl primer interface. The delamination occurred from an artificial defect(cutter scribing) and from ageing in a salt spray chamber.

Electrochemical Impedance Imaging via the Distribution of Diffusion Times [PDF]

open access: yes, 2017
We develop a mathematical framework to analyze electrochemical impedance spectra in terms of a distribution of diffusion times (DDT) for a parallel array of random finite-length Warburg (diffusion) or Gerischer (reaction-diffusion) circuit elements.
