HZB magazine lichtblick - the new issue is out!
In his search for the perfect catalyst, HZB researcher Robert Seidel is now getting a tailwind – thanks to a ERC Consolidator Grant. In the cover story, we explain why the X-ray source BESSY II plays an important role for his research.
Bernd Rech has just started his second term of office. What are his plans? In this interview, he reveals the role that basic research plays, but also why a good working atmosphere is important to him. Read more on page 8.

- Ultrafast dissociation of molecules studied at BESSY IIFor the first time, an international team has tracked at BESSY II how heavy molecules – in this case bromochloromethane – disintegrate into smaller fragments when they absorb X-ray light. Using a newly developed analytical method, they were able to visualise the ultrafast dynamics of this process. In this process, the X-ray photons trigger a "molecular catapult effect": light atomic groups are ejected first, similar to projectiles fired from a catapult, while the heavier atoms - bromine and chlorine - separate more slowly.
- 20 years of promoting science in the school lab38,000 visitors in 20 years: high demand shows need for science education
Twenty years ago, on 29 November 2004, Klaus Böger, then Senator for Education in Berlin, opened one of the capital's first school laboratories. Since then, Helmholtz-Zentrum Berlin (HZB), in cooperation with the Berlin Senate, has successfully promoted science education through project days and further training in the school lab.
- Battery research with the HZB X-ray microscopeNew cathode materials are being developed to further increase the capacity of lithium batteries. Multilayer lithium-rich transition metal oxides (LRTMOs) offer particularly high energy density. However, their capacity decreases with each charging cycle due to structural and chemical changes. Using X-ray methods at BESSY II, teams from several Chinese research institutions have now investigated these changes for the first time with highest precision: at the unique X-ray microscope, they were able to observe morphological and structural developments on the nanometre scale and also clarify chemical changes.
