Senior Expert Chemists (SEC) were present at the GDCh Science Forum in Bremen from 4 - 7 September 2011 with scientific presentations and posters (see also Nachr Chem. 2011, 59, 709). The motto of the Science Forum was "Chemistry creates the future," and the SEC presentations were entitled "Biographical and chemical topics." Many, but not all, of the presentations are available as PDFs. If you are interested, please send an email to Wolfgang Gerhartz
