Journal: Electrochimica Acta → Special issue: Distribution of Relaxation Time Analysis for Solid State Electrochemistry

Senior researcher of the Institute, Dmitry Medvedev (DSc(Chemistry) was invited as a Guest Editor to one of the leading scientific journals in the field of electrochemistry – Electrochimica Acta. A special issue has been launched as a platform for discussion of the DRT (distribution of relaxation times) method application for analysis of the impedance spectra and proper understanding of the processes, taking place in the solid oxide electrochemical devices.

Nearly 30 papers were submitted for publication in this issue. However, the review process was strict, some works were subjected 4 times (!) for revision. As a result, 16 papers including 4 papers presented by the IHTE authors were finally accepted for publication. They were classified into three main sections (additional information is provided below and in Tw).

We would like to thank all the authors and reviewers that have contributed to this unique special issue!
