Sixth Joint BER II and BESSY II User Meeting
The annual Joint HZB User Meetings will provide an overview of the many exciting and inspiring research results obtained at our facilities in the past year. The Sixth Joint BER II and BESSY II User Meeting will take place at Berlin-Adlershof from December 3rd to December 5th, 2014. The neutrons session will take place at Berlin-Wannsee on Wednesday, 3rd December, followed by Dinner at Café Jahn.
On Thursday morning, at WISTA, Bunsen Auditorium, Adlershof, Christof Wöll, KIT, will ask in his keynote lecture “What Supramolecular Chemistry can do for Solid State Physics?” The meeting continues with plenary talks, discussions, and a poster session, which will provide vast possibilities of information and discussion. In his public lecture, Christoph Lienau, University Oldenburg, will give an overview on “Solar cells and artificial light harvesting systems”.
Traditional highlights are the bestowals of the Prizes for Young Scientists donated by the “Freundeskreis Helmholtz-Zentrum Berlin e. V. “
After hours of inspiring scientific presentations we hope to meet you Thursday evening at the Berliner Buffet. The buffet is sponsored by the companies participating in the accompanying vendor exhibition. As well as this generous gesture the exhibitors will be happy to have the opportunity to inform you on the latest developments in all fields of research equipment.

- 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.
