On 23 April 2026, the annual Girl’s Day took place, giving pupils an insight into various career paths in the fields of science and technology. 83 pupils visited the Adlershof and Wannsee sites and enjoyed a day full of exciting experiments.
By taking part in various workshops, the girls were able to gain an insight into careers such as physicist, engineer and chemist.
Girls’ Day is an important initiative designed to inspire pupils to take an interest in science and technology and to encourage them to pursue careers in these fields.
HZB’s research topics were explored in a fun and engaging way across 16 different workshops.
Wannsee:
- Jules Verne’s dream: water as the coal of the future
- Using colours, electricity and chemistry, we make the invisible visible!
- Kitchen Tetris in the canteen’s shell
- Basics of HTML & CSS
- Atom by atom – thin films for the technology of the future
- Crystals – how are they structured and how can they be studied?
- Creative programming
Smart wires in the student lab
Adlershof:
- Particle accelerators – big and small
- Hot Stuff – solar energy you can touch (almost!)
- Soldering LED earrings
- The daily work of laboratory technicians at HZB and the production of perovskite solar cells
- The power of metadata: tagging, searching, finding!
- Chocolate lithography and what it has to do with solar cells
- Light programming: a creative introduction to programming
- Molecule detectives: searching for clues with NMR
We would like to extend our heartfelt thanks to all our colleagues whose dedication helped ensure that Girls’ Day at HZB could take place with such a diverse and exciting range of workshops.
The next opportunity to get to know us and carry out small experiments yourself will be at the Long Night of Science on 6 June at the HZB Adlershof site. With lots of exciting activities especially for children and young people!
- VOLT – Art in the shell of the HZB from 19 to 21 June 2026An extraordinary setting: from 19 to 21 June, artists and students from the Berlin University of the Arts will be exhibiting in the shell of the services building on the HZB campus in Berlin-Adlershof. The public is warmly invited to attend the three-day exhibition.
- Come along to the Long Night of Science on 6 June from 5 pm to midnightWhat does light reveal about materials? How are new medicines developed? And just how cold is liquid nitrogen? During the Long Night of Science, we’re opening our doors and inviting visitors on a journey of discovery through the world of research.
- Magnetic field during catalyst synthesis triples ammonia yieldApplying an external magnetic field during the synthesis of CoFe₂O₄ electrocatalysts triples the ammonia yield during electrocatalytic conversion. The magnetic field alters the surface states of the spinel oxide thin films, making catalytically active sites more accessible. In the journal 'Advanced Functional Materials', a team led by Marcel Risch at HZB and Sanjay Mathur at University of Cologne demonstrates a scalable strategy for developing next-generation electrocatalysts for efficient and sustainable chemical production.
