Sciences at HZBblog.de

The Blog http://science.hzbblog.de is a place, where we mention nice papers of HZB scientists, too specialized for the mass media, but really interesting for colleagues and experts. We also might link to relevant articles in science journals and we would be glad if you want to contribute to this blog.

    PhD students at HZB: Friends for Life

    At HZB about 150 young scientists are working on their doctoral dissertation. 81 come from abroad to Berlin to do their PhD in the HZB labs in Wannsee or Adlershof. The PhD students at HZB have organized themselves: twice a month, they invite to an informal get-together, they plan workshops and an annual PhD retreat in a country hotel in Brandenburg. This is actively supported by the management. I recently asked Daniel Meza, one of eight current doctoral student representatives about their activities. Daniel, why do you work as a representative in the PhD students organization ? Daniel: Maybe it’s a bit romantic, but forRead More →Der Beitrag PhD students at HZB: Friends for Life [...].

    Users at BESSY II: Nafion, the talented membrane for fuel cells and 4D-printing

    Thermoplastic ionomer materials such as Nafion do have many talents: they can be used as membranes for proton exchange in fuel cells, but they have also attracted attention as shape memory materials: Via external stimuli such as heat or an electric field, it is possible to trigger a change in shapes. Applications in textiles, biomedicine, aerospace, sensors and coatings are possible. Nafion: a membrane with shape memory Nafion is one of those materials: as a membrane in a fuel cell, its high proton conductivity allows a fast pass of hydrogen ions (protons). And its internal shape plays a crucial role. Now a team from Brazil hasRead More →Der Beitrag Users at BESSY II: Nafion, the [...].

    The long way of undulators: 70 years old and still up-to-date

    by Jonas Böhm The last finishing touches are being made to the cryogenic undulator CPMU-17 before it will be installed in the BESSY II storage ring next week. A good moment to look back. The long way of undulators: 70 years old and still up-to-date Home of the first undulator was Stanford. Its linear accelerator (you can see its tunnel in the image) is claimed to be “the world’s most straight object”. In 1952, the Austrian scientist Hans Motz and his team conducted the first experiment, in which a 100-Mev electron beam from the Stanford linear accelerator passed through the undulator. Light radiated by the beam wasRead More →Der Beitrag The long way of undu [...].
