Invitation to the HZB Science Slam: TODAY at 18.30 o’clock in Adlershof
We invite you to the HZB Science Slam that takes place today at 18.30 o’clock at the Melli Beese Kabinett (Adlershof Forum). Three scientists present their topics in an understandable, entertaining and concise way and, moreover, in only 10 minutes. The audience is the judge and jury, voting using numbered cards. This participation provokes discussion as they begin to talk about science and the presentation. The Science Slam is part of the HZB User Meeting.
The Science Slamers are:
Christan Gollwitzer; Physikalisch-Technische Bundesanstalt
Tobias Bock, Helmholtz-Zentrum für Infektionsforschung
Janik Wolters, Technische Universität Berlin
The presentations are in English.
Time and location
18.30 - 21.00
Melli Beese Kabinett
Forum Adlershof
Rudower Chaussee 24
12489 Berlin
The admission is free.
- Largest magnetic anisotropy of a molecule measured at BESSY IIAt the Berlin synchrotron radiation source BESSY II, the largest magnetic anisotropy of a single molecule ever measured experimentally has been determined. The larger this anisotropy is, the better a molecule is suited as a molecular nanomagnet. Such nanomagnets have a wide range of potential applications, for example, in energy-efficient data storage. Researchers from the Max Planck Institute for Kohlenforschung (MPI KOFO), the Joint Lab EPR4Energy of the Max Planck Institute for Chemical Energy Conversion (MPI CEC) and the Helmholtz-Zentrum Berlin were involved in the study.
- Ultrafast dissociation of molecules studied at BESSY IIFor the first time, an international team has tracked at BESSY II how heavy molecules – in this case bromochloromethane – disintegrate into smaller fragments when they absorb X-ray light. Using a newly developed analytical method, they were able to visualise the ultrafast dynamics of this process. In this process, the X-ray photons trigger a "molecular catapult effect": light atomic groups are ejected first, similar to projectiles fired from a catapult, while the heavier atoms - bromine and chlorine - separate more slowly.
- Battery research with the HZB X-ray microscopeNew cathode materials are being developed to further increase the capacity of lithium batteries. Multilayer lithium-rich transition metal oxides (LRTMOs) offer particularly high energy density. However, their capacity decreases with each charging cycle due to structural and chemical changes. Using X-ray methods at BESSY II, teams from several Chinese research institutions have now investigated these changes for the first time with highest precision: at the unique X-ray microscope, they were able to observe morphological and structural developments on the nanometre scale and also clarify chemical changes.
