HZB-magazine lichtblick - the new issue is out!
In the cover story we introduce Astrid Brandt. She is Head of User Coordination at Helmholtz-Zentrum Berlin. She and her team keep constant track of applications, measurement times and publications of the 1000 guest researchers who come to BESSY II each year.
She has always been fascinated by science. But she has also never let go of her other passion, which is music.

- New HZB magazine "Lichtblick" has been publishedIn 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.
- 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.
- Shedding light on insulators: how light pulses unfreeze electronsMetal oxides are abundant in nature and central to technologies such as photocatalysis and photovoltaics. Yet, many suffer from poor electrical conduction, caused by strong repulsion between electrons in neighboring metal atoms. Researchers at HZB and partner institutions have shown that light pulses can temporarily weaken these repulsive forces, lowering the energy required for electrons mobility, inducing a metal-like behavior. This discovery offers a new way to manipulate material properties with light, with high potential to more efficient light-based devices.
