Dear team, Now that this unusual year, marred not only by the Corona pandemic but also by a series of deaths and serious accidents around us, draws to an end, I wanted to thank you for your engagement, endurance and optimism. Please keep on tabulating the positives and not the negatives. Merry Christmas, and to those whom I will only see again in 2021, a Happy New Year, PK -- ------------------------------------------------ Univ.-Prof. Dr. Paul Kögerler Institut für Anorganische Chemie RWTH Aachen University Landoltweg 1 D-52074 Aachen Tel.: +49-241-80-94657 Fax: +49-241-80-92642 Peter-Grünberg-Institut -- PGI-6 Forschungszentrum Jülich D-52425 Jülich Tel.: +49-2461-61-3159 Fax: +49-2461-61-2610 www.koegerler.ac.rwth-aachen.de ------------------------------------------------
