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.
- Catalysis research with the X-ray microscope at BESSY IIContrary to what we learned at school, some catalysts do change during the reaction: for example, certain electrocatalysts can change their structure and composition during the reaction when an electric field is applied. The X-ray microscope TXM at BESSY II in Berlin is a unique tool for studying such changes in detail. The results help to develop innovative catalysts for a wide range of applications. One example was recently published in Nature Materials. It involved the synthesis of ammonia from waste nitrates.
- BESSY II: Magnetic ‘microflowers’ enhance magnetic fields locallyA flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the geometry and number of 'petals'. This magnetic metamaterial developed by Dr Anna Palau's group at the Institut de Ciencia de Materials de Barcelona (ICMAB) in collaboration with her partners of the CHIST-ERA MetaMagIC project, has now been studied at BESSY II in collaboration with Dr Sergio Valencia. Such a device can be used to increase the sensitivity of magnetic sensors, to reduce the energy required for creating local magnetic fields, but also, at the PEEM experimental station, to study samples under much higher magnetic fields than currently possible.
- 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.
