Birgit Kanngießer is setting up a joint research group to combine X-ray methods in laboratories and at large-scale facilities. In particular, the physicist wants to investigate how X-ray experiments on smaller laboratory instruments can be optimally complemented with more complex experiments that are only possible at synchrotron sources such as BESSY II.
Prof. Dr. Birgit Kanngießer is professor of analytical X-ray Physics at the Technische Universität Berlin, where she also heads a large research group. Together with the Max Born Institute she has build up BLiX (Berlin laboratory for innovative X-ray technologies), which brings established X-ray methods from the synchrotron into the laboratory. At BESSY II she was involved as one of the first users from the early on.
Now HZB and TU Berlin are funding a joint research group headed by Birgit Kanngießer to strengthen this cooperation. This should also accelerate the exchange of knowledge and technology between BESSY II and university laboratories.
The joint research group is called 'Combined X-ray methods at BLiX and BESSY II - SyncLab'. On the TU Berlin side, the Berlin laboratory for innovative X-ray technologies (BLiX) is integrated. Kanngießer will initially focus on evaluating how time-resolved measurements using near-edge X-ray spectroscopy in the soft X-ray range on smaller instruments and at BESSY II could complement each other. Further analytical and imaging X-ray methods are to follow in the future.
- Battery research: visualisation of aging processes operandoLithium button cells with electrodes made of nickel-manganese-cobalt oxides (NMC) are very powerful. Unfortunately, their capacity decreases over time. Now, for the first time, a team has used a non-destructive method to observe how the elemental composition of the individual layers in a button cell changes during charging cycles. The study, now published in the journal Small, involved teams from the Physikalisch-Technische Bundesanstalt (PTB), the University of Münster, researchers from the SyncLab research group at HZB and the BLiX laboratory at the Technical University of Berlin. Measurements were carried out in the BLiX laboratory and at the BESSY II synchrotron radiation source.
- New instrument at BESSY II: The OÆSE endstation in EMILA new instrument is now available at BESSY II for investigating catalyst materials, battery electrodes and other energy devices under operating conditions: the Operando Absorption and Emission Spectroscopy on EMIL (OÆSE) endstation in the Energy Materials In-situ Laboratory Berlin (EMIL). A team led by Raul Garcia-Diez and Marcus Bär showcases the instrument’s capabilities via a proof-of-concept study on electrodeposited copper.
- Green hydrogen: A cage structured material transforms into a performant catalystClathrates are characterised by a complex cage structure that provides space for guest ions too. Now, for the first time, a team has investigated the suitability of clathrates as catalysts for electrolytic hydrogen production with impressive results: the clathrate sample was even more efficient and robust than currently used nickel-based catalysts. They also found a reason for this enhanced performance. Measurements at BESSY II showed that the clathrates undergo structural changes during the catalytic reaction: the three-dimensional cage structure decays into ultra-thin nanosheets that allow maximum contact with active catalytic centres. The study has been published in the journal ‘Angewandte Chemie’.
