On 28 June, it's that time again: the Long Night of Science will take place from 5 pm to midnight in Berlin and also in Adlershof! Come around and take a look behind the scenes of our exciting research.
We will open the doors of our laboratories and BESSY II light source to you, your families and friends. Meet scientists who will tell you about the latest breakthroughs in energy and materials research: batteries, solar cells and catalysts are the focus of our work at HZB!
Children of all ages will also have lots to discover. An extra programme with experiments in our school laboratory awaits you.
> Please find here the programme (BESSY II light source and Kekuléstraße)
And last but not least, some great news: the Long Night of Science is celebrating its 25th anniversary. To mark the occasion, there is a special gift: all tickets cost just 5 euros this year! Info Tickets
We cannot wait to see you at Helmholtz-Zentrum Berlin!
- Porous Radical Organic framework improves lithium-sulphur batteriesA team led by Prof. Yan Lu, HZB, and Prof. Arne Thomas, Technical University of Berlin, has developed a material that enhances the capacity and stability of lithium-sulphur batteries. The material is based on polymers that form a framework with open pores (known as radical-cationic covalent organic frameworks or COFs). Catalytically accelerated reactions take place in these pores, firmly trapping polysulphides, which would shorten the battery life. Some of the experimental analyses were conducted at the BAMline at BESSY II.
- Metallic nanocatalysts: what really happens during catalysisUsing a combination of spectromicroscopy at BESSY II and microscopic analyses at DESY's NanoLab, a team has gained new insights into the chemical behaviour of nanocatalysts during catalysis. The nanoparticles consisted of a platinum core with a rhodium shell. This configuration allows a better understanding of structural changes in, for example, rhodium-platinum catalysts for emission control. The results show that under typical catalytic conditions, some of the rhodium in the shell can diffuse into the interior of the nanoparticles. However, most of it remains on the surface and oxidises. This process is strongly dependent on the surface orientation of the nanoparticle facets.
- Key technology for a future without fossil fuelsIn June and July 2025, catalyst researcher Nico Fischer spent some time at HZB. It was his sabbatical, he was relieved of his duties as Director of the Catalysis Institute in Cape Town for several months and was able to focus on research only. His institute is collaborating with HZB on two projects that aim to develop environmentally friendly alternatives using innovative catalyst technologies. The questions were asked by Antonia Rötger, HZB.
