On May 31, 2022, Prof. Ingrid Milošev, Head of Department fof Physical and Organic Chemistry at Jožef Stefan Institute presented a webinar within the second season of the CorroZoom, series organized by Prof. G. S. Frankel at The Ohio State University, Columbus, USA. This year, six top scientists from all over the world gave lectures on different corrosion-related topics, where Prof. Milošev had the honor of concluding the second season. Lecture entitled "Cerium conversion coatings on aluminium alloys" covered some fundamental considerations of the chemistry of Ce salts and general mechanisms of coatings formation, followed by examples from her group's research work on this type of coatings. The lecture, attended by around 300 participants worldwide, was followed by a broad discussion on the topic. Presenting at the CorroZoom webinar is a great acknowledgment and compliment to Prof. Milošev's over three decades-long research work dedicated to corrosion protection, including conversion coatings.
