Abstract:

Transmission electron microscopy (TEM) enables evaluation of microstructural and chemical variations at high-resolution. However, ex-situ and quasi in-situ studies of dehydrated surfaces hardly represent the real interfacial conditions. Additionally, artefacts and contaminations might be introduced into the system during the ex-situ and quasi in-situ experiments. MicroElectronic Machined Systems (MEMS) are developed for fabrication of operando facilities such as in-situ nanoreactors with controllable temperature and/or electric field in real environments, e.g. gases or liquids. Transmission operando nanoscopy (TON) becomes increasingly fascinating, allowing a.o. real-time microstructural evolution upon heating, and microscopy of the interfacial phenomena at small scales including corrosion initiation and inhibition processes. However, challenges remain for future investigations since the measurements are influenced by the sample and reactor geometry and thickness as well as the electron beam effect on the surface and solution compositions.

This presentation will focus on the (im)possibilities, application areas and research challenges we face for local and in-situ electrochemical techniques, also when combined with (quasi) in-situ microscopic and spectroscopic techniques.

ABRIDGED CURRICULUM VITAE

As from 2006 Arjan Mol returned to DUT-MSE and now is Full Professor ‘Corrosion Technology and Electrochemistry’.

Besides, Arjan Mol is Working party Chairman ‘Physico-chemical methods for Corrosion Research’ and in the period of 2014-2016 he was Chairman of the Scientific and Technology Advisory Committee (STAC) of the European Corrosion Federation EFC (www.efcweb.org). In 2016 he was elected to become Vice-President of the EFC, and as such Member of the Board of Administrators, as from 2017. He will be President of the EFC as from 2019 for two years.

The specific research focus areas of Arjan Mol are:

- Local electrochemical analysis of corrosion mechanisms

- Surface treatment and interfacial bonding of organic coatings on metal (oxide) surfaces

- Multifunctional and eco-friendly corrosion inhibitors and evaluation of active protective coatings

Arjan Mol has published over 150 Web of Science listed papers in international peer refereed scientific journals, 14 book chapters, 1 book as co-editor and over 100 international conference proceeding papers.
