Editorial 1 Tribologie + Schmierungstechnik · 69. Jahrgang · eOnly Sonderausgabe 2/ 2022 DOI 10.24053/ TuS-2022-0031 As spokesperson of the Steering Committee of the 23 rd International Colloquium Tribology 2022, I was involved in the preparations at the TAE from the very beginning. In doing so, I pursued the goal of realising an interesting mixture between very experienced tribologists as well as professional younger tribologists and to bring the latter more clearly to the fore, especially for the participants from industry. The Tribology Colloquium was intended to be an on-site event - but considering the Covid experiences at that time, it was necessary to change to a virtual event. Due to general conditions, the programme had to be focused on about 145 presentations, 6 parallel lecture series and 3 days. I would like to take the opportunity to thank and acknowledge the TAE team for providing the technical basis for the virtual event and for the organisational support during the event. The 23 rd International Colloquium Tribology covered a broad spectrum of current tribological topics in its various disciplines: It focused on new trends in lubricants and additives, test methods and measurement technologies, coatings, surfaces, and underlying mechanisms with the key topics of sustainability, including e-mobility and digitalization in tribology. Five contributions from scientifically active authors on this range of topics were selected and are included in the present edition as a long version. What does the future of the International Colloquium Tribology look like? The preparations for the 24 th event in January 2024 have already begun. We consider that a face-to-face event will be possible again. Exactly these networking opportunities represented the key item of attraction for many participants of the previous events of the TAE. But the virtual participation option will remain, if only to enable participants from regions far away to take part in a timeand cost-efficient way. However, in view of climate change, don't we have to admit that a purely virtual event, which avoids individual journeys to the venue, is the more environmentally friendly solution? Perhaps I am already too old for this or have attended the Tribology Colloquium at TAE too many times in person to be enthusiastic about such a change. Here the hope remains that the next generations of tribologists will find more sustainable solutions, because tribological knowledge is indispensable for sustainability in human activity. Therefore, I am actively involved in ensuring that responsibility is also placed on younger shoulders in the Steering Committee for the coming event and that they hopefully tread new paths, and I will contribute to the Tribology Colloquium 2024 in the second row. The new lecture topics will cover all current aspects of modern tribology. Special attention will be paid to networking between speakers and participants from industry and research organisations in an international atmosphere, exhibitors are invited to display their services and products and you can look forward to an exciting social programme. So don´t miss this leading event on tribology and be a part of it. We look forward to welcoming you at Ostfildern/ Stuttgart in January 2024.
