Are you a 10th to 13th grade student interested in mathematics and science? Then secure your free VIP ticket for a tour with exciting experiments and insights during the Long Night of Science! Meet female scientists who are passionate about making our world a better place! 17.06. , from 5.30 pm, Adlershof Research Campus.
Come along on a discovery tour and get to know interesting research labs that are otherwise closed. At the Helmholtz-Zentrum Berlin you will take part in a workshop and make earrings out of colourful LEDs with a soldering iron. You'll also learn why female mechatronics engineers should love one thing: tinkering and being creative.
The tour also takes you to Humboldt University and the Federal Institute for Materials Research and Testing. Learn about renewable energies and nano-optics or take a heat selfie. Join us and immerse yourself in the world of science for an evening!

- 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’.
- An elegant method for the detection of single spins using photovoltageDiamonds with certain optically active defects can be used as highly sensitive sensors or qubits for quantum computers, where the quantum information is stored in the electron spin state of these colour centres. However, the spin states have to be read out optically, which is often experimentally complex. Now, a team at HZB has developed an elegant method using a photo voltage to detect the individual and local spin states of these defects. This could lead to a much more compact design of quantum sensors.
