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“.
- The future of corals – what X-rays can tell usThis summer, it was all over the media. Driven by the climate crisis, the oceans have now also passed a critical point, the absorption of CO2 is making the oceans increasingly acidic. The shells of certain sea snails are already showing the first signs of damage. But also the skeleton structures of coral reefs are deteriorating in more acidic conditions. This is especially concerning given that corals are already suffering from marine heatwaves and pollution, which are leading to bleaching and finally to the death of entire reefs worldwide. But how exactly does ocean acidification affect reef structures?
Prof. Dr. Tali Mass, a marine biologist from the University of Haifa, Israel, is an expert on stony corals. Together with Prof. Dr. Paul Zaslansky, X-ray imaging expert from Charité Berlin, she investigated at BESSY II the skeleton formation in baby corals, raised under different pH conditions. Antonia Rötger spoke online with the two experts about the results of their recent study and the future of coral reefs.
- Energy of charge carrier pairs in cuprate compoundsHigh-temperature superconductivity is still not fully understood. Now, an international research team at BESSY II has measured the energy of charge carrier pairs in undoped La₂CuO₄. Their findings revealed that the interaction energies within the potentially superconducting copper oxide layers are significantly lower than those in the insulating lanthanum oxide layers. These results contribute to a better understanding of high-temperature superconductivity and could also be relevant for research into other functional materials.
- Electrocatalysis with dual functionality – an overviewHybrid electrocatalysts can produce green hydrogen, for example, and valuable organic compounds simultaneously. This promises economically viable applications. However, the complex catalytic reactions involved in producing organic compounds are not yet fully understood. Modern X-ray methods at synchrotron sources such as BESSY II, enable catalyst materials and the reactions occurring on their surfaces to be analysed in real time, in situ and under real operating conditions. This provides insights that can be used for targeted optimisation. A team has now published an overview of the current state of knowledge in Nature Reviews Chemistry.
