Invitation to the HZB Science Slam: TODAY at 18.30 o’clock in Adlershof
We invite you to the HZB Science Slam that takes place today at 18.30 o’clock at the Melli Beese Kabinett (Adlershof Forum). Three scientists present their topics in an understandable, entertaining and concise way and, moreover, in only 10 minutes. The audience is the judge and jury, voting using numbered cards. This participation provokes discussion as they begin to talk about science and the presentation. The Science Slam is part of the HZB User Meeting.
The Science Slamers are:
Christan Gollwitzer; Physikalisch-Technische Bundesanstalt
Tobias Bock, Helmholtz-Zentrum für Infektionsforschung
Janik Wolters, Technische Universität Berlin
The presentations are in English.
Time and location
18.30 - 21.00
Melli Beese Kabinett
Forum Adlershof

The admission is free.
- 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.
- BESSY II: New procedure for better thermoplasticsBio-based thermoplastics are produced from renewable organic materials and can be recycled after use. Their resilience can be improved by blending bio-based thermoplastics with other thermoplastics. However, the interface between the materials in these blends sometimes requires enhancement to achieve optimal properties. A team from the Eindhoven University of Technology in the Netherlands has now investigated at BESSY II how a new process enables thermoplastic blends with a high interfacial strength to be made from two base materials: Images taken at the new nano station of the IRIS beamline showed that nanocrystalline layers form during the process, which increase material performance.
- Alternating currents for alternative computing with magnetsA new study conducted at the University of Vienna, the Max Planck Institute for Intelligent Systems in Stuttgart, and the Helmholtz Centers in Berlin and Dresden takes an important step in the challenge to miniaturize computing devices and to make them more energy-efficient. The work published in the renowned scientific journal Science Advances opens up new possibilities for creating reprogrammable magnonic circuits by exciting spin waves by alternating currents and redirecting these waves on demand. The experiments were carried out at the Maxymus beamline at BESSY II.
