🎉 Happy to share our latest publication!

“Quantitative correlation between cyclic voltammetry and electrochemical impedance spectroscopy models on TiO₂ film electrodes”, now published as open access article in Chemical Engineering Science. DOI: https://doi org/10.1016/j.ces.2026.125.139.
https://www.sciencedirect.com/science/article/pii/S0009250926018543?via%3Dihub.

This work comes from a fruitful collaboration with J. C. Ciria from Unizar, where mathematical modelling was combined with our experimental CV and EIS results on TiO₂ photoelectrodes.

One of the key outcomes is that CV and EIS can provide quantitatively equivalent descriptions under specific conditions, while their deviations can reveal electrochemical processes taking place at different time scales.

A great example of how theory and experiment can work together to better understand complex electrochemical systems, as part of our project PhotoGrapH2 (PID2022-139671OB-I00).

Congratulations to all the authors!

Our colleague Wolfgang Maser attended ISyDMA conference in Chisinau (Moldova), https://isydma10.utm.md/, where he delivered an invited key note lecture on Carbon Nanomaterials as Dielectric-Active Interfaces. He enjoyed a wonderful meeting with plenty of dicussions with great colleagues from all over the world. He would like to thank the organisers for this excellent meeting, and overall, for their kind hospitality, in particular to Prof. Dumitru Tsiulanyu from Technical University of Moldova.
