Energymaterials at HZBblog.de

The Blog www.energymaterials.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.

    Materials scientist Manuela Klaus uses high tech methods to study samples from industry

    It was after a telephone call in 2003 that Manuela Klaus?s career took off. Right about the time Klaus had just graduated in materials sciences from TU Berlin, the phone rang in the office of Christoph Genzel of the Microstructure and Residual Stress Analysis department. ?It was a drill bit manufacturing company from Baden-Württemberg calling,? the department head recollects. The callers needed help with improving their drill bits: they wanted to measure the residual stress of the material at the precise points where the bits are most stressed ? ?and I said there are no methods to do that yet. But I know of justRead More →Der Beitrag Materials scientist Manuela Klaus uses high tech met [...].

    Solar cities: feasible but not yet realised

    At the Interdisciplinary conference on ?INNOVATION IN SOLAR BUILDING SKINS & ENERGY EFFICIENCY TOWARDS SUSTAINABLE CITIES?, 19th to 20th march in Berlin, experts from the building sector, politics, finance and photovoltaics discussed why Building Integrated Photovoltaics (BIPV) is not already more widely applied in buildings (see also HZB-webinfo ) and what innovations are still needed. Statements from participants of the conference:   Lighthouse projects show what is possible Impressive projects by architects and engineering offices demonstrate what can be done already: Elegant modern buildings with solar facades and solar active materials for windows, pavements or other surfaces d [...].

    ?Bethe strings? experimentally observed for the first time

    Even if quantum physics is well established since roughly ninety years, there are still some quantum effects in matter which have been theoretically predicted but up to now not yet seen experimentally. It was the physicist Hans Bethe, who first described theoretically in 1931 what happens in a one dimensional quantum spin system: under certain conditions, magnetic  excitations may interact and give rise to a collective excitation, known as ?Bethe strings?.  But in real matter, strictly one dimensional systems are rare, so Bethe strings have not been a common phenomenon. Now those Bethe strings have been discovered for the first time experimentally by the AugsburgRead More →De [...].
