More than 600 scientists registered this year for the 9th annual BER II and BESSY II User Meeting from Wednesday to Friday, 13-15 December 2017. The Friends of Helmholtz-Zentrum Berlin recognised outstanding work in the field of synchrotron radiation with an Innovation Award, and the best doctoral dissertation with the Ernst-Eckard-Koch prize.
Research with synchrotron radiation was the focus on Wednesday. On Thursday, the „Science Day“, a broad overview on user research was given. The public talk entitled “Interfacing with the brain using organic electronics” found great appeal with the audience: George Malliaras from the University of Cambridge spoke about the potential of organic electronics as brain implants for treating neurological diseases such as epilepsy. New materials and their characterisation at synchrotron sources will play a crucial role in this development. A vendor exhibition by 56 companies on new technical and optical instruments for research was well visited by the scientists.
Highly motivated were all the young scientists who could present their research in Young Scientist Sessions at Wednesday (synchrotron radiation) and Friday (neutron research).
The Neutron Day on Friday offered talks covering new methods and results using neutrons. The satellite workshop entitled “Diffraction Data Processing using DIALS – a practical workshop” took place in parallel.
Poster prizes of HZB Usermeeting
Thursday evening, in the experimental hall at BESSY II, nearly 200 posters from users and HZB scientists were presented. A jury had the difficult task to select the best poster. The poster prize of this HZB usermeeting was given to Katrein Sauer for her Poster on „Fish (Pike) have evolutionary advanced damage resistant bones with layered lamellae different from mammal bones“.
A special poster award in the field of protein crystallography was given by Manfred Weiss and his team to Julia Kratky, University of Leipzig. Her Poster with the title "Structural studies on the substrate and cofactor binding mode of FAD-dependent monooxygenases” presented a new synthesis for the blue dye indigo.
Friends of Helmholtz-Zentrum Berlin: Prize ceremony
The Friends of Helmholtz-Zentrum Berlin bestowed the Innovation Award upon a team of physicists from DESY, Hamburg: Dr. Bart Faatz, Dr. Evgeny Schneidmiller, Dr. Siegfried Schreiber, Dr. Markus Tischer and Dr. Mikhail Yurkov have been awarded for their work on „Innovative applications of gap-tunable undulators with integrated phase shifters in SASE x-ray FELs“.
The Ernst-Eckard-Koch prize, likewise awarded by the Friends of HZB, went this year to Dr. Nele Thielemann-Kühn her doctoral dissertation (at Uni Potsdam and HZB) on „Optically induced ferro- and antiferromagnetic dynamics in the rare-earth metal dysprosium“.
- 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.
- Hydrogen: Breakthrough in alkaline membrane electrolysersA team from the Technical University of Berlin, HZB, IMTEK (University of Freiburg) and Siemens Energy has developed a highly efficient alkaline membrane electrolyser that approaches the performance of established PEM electrolysers. What makes this achievement remarkable is the use of inexpensive nickel compounds for the anode catalyst, replacing costly and rare iridium. At BESSY II, the team was able to elucidate the catalytic processes in detail using operando measurements, and a theory team (USA, Singapore) provided a consistent molecular description. In Freiburg, prototype cells were built using a new coating process and tested in operation. The results have been published in the prestigious journal Nature Catalysis.
