The International Chemistry Olympiad (IChO) has ended after an exciting event. Talented chemists from 89 countries showcased their skills and became acquainted not only with Switzerland but also with ETH Zurich and the D-CHAB. A review with many pictures.

The 55th International Chemistry Olympiad ended with a closing ceremony on Monday afternoon, 24 July. Out of 348 participants, 217 were awarded gold, sil-​ver, or bronze medals. The Swiss team took home an "honourable mention."

Helma Wennemers, Professor at the Institute of Organic Chemistry at the D-CHAB, is the moderator of the International Chemistry Olympiad opening ceremony, taking place today. In this short video interview, Professor Wennemers talks about her fascination for collagen, the importance of serendipity, chemistry as a subject for men and women, and she explains why chemistry in particular has the ability to bring people together, no matter what country they come from.

ETH Zurich will host the International Chemistry Olympiad (IChO) between 16 and 25 July. More than 300 young scientists from some 90 countries are expected to participate. This is the first time that Switzerland is hosting the event.

In deepest grief, the Laboratory of Organic Chemistry announces that our friend and colleague, Prof. em. Albert Eschenmoser passed away peacefully, at the age of 97, on July 14, 2023.
