Postdocs at HZB: Crucial for research, innovation and diversity
At HZB, 117 postdocs from 29 countries are employed. They play a crucial role in driving the main research activities, fostering creativity and innovation. To honor them, the Postdoc Appreciation Week was first organised in the USA in 2009 and has in the meantime become a regular event in Germany as well in the third week of September every year.
The Postdoc Appreciation Week will take place from 16 to 20 September 2024 and is an important occasion to recognise and celebrate postdocs for their significant contributions to research and academic life.
Bernd Rech, Scientific Director of HZB, emphasizes: "Our postdocs make a crucial contribution to scientific progress at HZB. They are not only involved in research but also contribute to the development of scientific infrastructures, take responsibility for supervising doctoral researchers, and support their career development. The Postdoc Appreciation Week is an excellent opportunity to highlight how indispensable our postdocs are to HZB, with their diversity and creativity."
During the Postdoc Appreciation Week, HZB postdocs have the opportunity to participate in various online trainings and events organized by institutions across Germany. More information about and registration sites for these events can be found here.
- Electrical energy storage: BAM, HZB, and HU Berlin plan joint Berlin Battery LabThe Federal Institute for Materials Research and Testing (BAM), the Helmholtz-Zentrum Berlin (HZB), and Humboldt University of Berlin (HU Berlin) have signed a memorandum of understanding (MoU) to establish the Berlin Battery Lab. The lab will pool the expertise of the three institutions to advance the development of sustainable battery technologies. The joint research infrastructure will also be open to industry for pioneering projects in this field.
- 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.
- 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’.
