Organized by the Institute of Organic Chemistry for more than a decade, the "Tag der Chemie am Hagenring" has become the key event at the end of each summer semester. Students and professors located in the Hagenring laboratories share the unique opportunity of coming together and celebrating their most recent results. Six talks are given by doctoral students from Organic and Inorganic Chemistry, and also from other fields in the house. Young students will learn about the exciting chemistry happening here. Please join the open-end summer party afterwards, generously sponsored by the FIOC and by the professors!
