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“.
- A new way to control the magnetic properties of rare earth elementsThe special properties of rare earth magnetic materials are due to the electrons in the 4f shell. Until now, the magnetic properties of 4f electrons were considered almost impossible to control. Now, a team from HZB, Freie Universität Berlin and other institutions has shown for the first time that laser pulses can influence 4f electrons- and thus change their magnetic properties. The discovery, which was made through experiments at EuXFEL and FLASH, opens up a new way to data storage with rare earth elements.
- HZB magazine lichtblick - the new issue is out!In his search for the perfect catalyst, HZB researcher Robert Seidel is now getting a tailwind – thanks to a ERC Consolidator Grant. In the cover story, we explain why the X-ray source BESSY II plays an important role for his research.
- BESSY II shows how solid-state batteries degradeSolid-state batteries have several advantages: they can store more energy and are safer than batteries with liquid electrolytes. However, they do not last as long and their capacity decreases with each charge cycle. But it doesn't have to stay that way: Researchers are already on the trail of the causes. In the journal ACS Energy Letters, a team from HZB and Justus-Liebig-Universität, Giessen, presents a new method for precisely monitoring electrochemical reactions during the operation of a solid-state battery using photoelectron spectroscopy at BESSY II. The results help to improve battery materials and design.
