New HZB magazine "Lichtblick" has been published
In the new issue, we introduce our new commercial managing director. We also show how important exchange is to us: science thrives on fruitful exchange with others. But dialogue with the public is also very important to us. Art can also create enriching access to science and build bridges. All these topics are covered in the new issue of Lichtblick.

A portrait of our Administrative director
The new Administrative Director, Saskia Vormfelde, took up her work in September – and brings more than just a knack for balance sheets to the table. You can read about what she has done so far and why she is looking forward to working at HZB in the cover story. > Portrait on the internet
What remains of the Helmholtz reviews in May?
Many colleagues were busy preparing for the programme-oriented research (PoF) reviews in the first half of 2025. In an interview, the two coordinators, Olaf Schwarzkopf and Tobias Sontheimer, talk about how the presentation was received by the reviewers. > Interview to read
The neuron accelerator brings art and research together
A place that invites brainstorming: artist Peter Sandhaus' neuron accelerator is designed to strengthen exchange and stimulate new ideas. The artwork has recently been installed in front of the entrance to the BESSY II building. > More about the artwork

Good advice in the service of science: Sebastian Fiechter is a long-standing ombudsperson for good scientific practice and talks about the problems that can arise.
Why we are becoming more public: Dialogue and exchange on an equal footing help to build trust in science. That's why we approach people at many festivals.
The internationality of our employees: How international are we really?
- AI agents deliver results – but do they reason scientifically?A research team co-led by Kevin Maik Jablonka from the Helmholtz Institute for Polymers in Energy Applications Jena (HIPOLE Jena) and N. M. Anoop Krishnan from the Indian Institute of Technology Delhi has developed Corral, a new benchmark for AI agents in science. The preprint “AI scientists produce results without reasoning scientifically” has been published on arXiv (https://doi.org/10.48550/arXiv.2604.18805). The analysis shows that current systems can execute scientific workflows and deliver results; however, they often do not follow the basic principles of scientific testing and reasoning.
- Materials chemistry shapes the future of catalysisThe synthesis of materials can serve as a tool for developing smart, adaptive electrocatalysts. This rapidly evolving field of research involves in-situ analytics, data-driven discoveries and autonomous robotics. These new approaches could accelerate the discovery of long-lasting and efficient catalysts for future energy conversion and the decarbonisation of the chemical industry. A recent article by Dr Prashanth Menezes and his team in the renowned journal Angewandte Chemie provides an overview of this research.
- BESSY II: How intrinsic oxygen shortens the lifespan of solid-state batteriesAlthough solid-state batteries (SSBs) demonstrate high performance and are intrinsically safe, their capacity currently declines rapidly. A team from the TU Wien, Humboldt-University Berlin and HZB has now analysed a TiS₂|Li₃YCl₆ solid-state half-cell in operando at BESSY II using a special sample environment that allows for non-destructive investigation under real operating conditions. Data obtained by combination of soft and hard X-ray photoelectron spectroscopy (XPS and HAXPES) revealed a new degradation mechanism that had not previously been identified in solid-state batteries. They have gained some surprising insights, particularly regarding the harmful role played by intrinsic oxygen. This study provides valuable information for improving design and handling of such batteries.
