It's official: The world's fastest movie was shot by DESY's X-ray laser FLASH in Hamburg. In its 2012 edition, the famous Guinness Book of World Records lists an interval of a mere 50 femtoseconds between two frames for FLASH. A femtosecond is a quadrillionth of a second, meaning that the two ...
HZB researchers achieve X-ray spectroscopy at nanoscale spatial resolution
Researchers at Helmholtz Zentrum Berlin (HZB) have developed a new microscope for high spatial resolution X-ray spectroscopic studies. While conventional X-ray spectroscopy has so far fallen short of resolving single nanoparticles, the X-ray microscope at HZB’s synchrotron source BESSY II ...
Scientists observe how a material at room temperature exhibits a unique property
Researchers at Helmholtz-Zentrum Berlin (HZB) in close collaboration with colleagues in France and UK, have engineered a material that exhibits a rare and versatile trait in magnetism at room temperature. It's called a "multiferroic," and it means that the material has properties allowing it to ...
So far, it has only been possible to image magnetic domains in two dimensions. Now, for the first time, Scientists at Helmholtz-Zentrum Berlin (HZB) have managed to create three-dimensional images of these domains deep within magnetic materials. Although they exist in almost every magnetic ...
HZB researchers may have observed the fastest melting of all time
Scientists from Helmholtz-Zentrum Berlin (HZB) observed exotic be-haviour from beryllium oxide (BeO) when they bombarded it with high-speed heavy ions: After being shot in this way, the electrons in the BeO appeared “confused”, and seemed to completely forget the material properties of their ...
HZB researchers solve the case of lost current in organic solar cells
Scientists have been working on organic solar cells for about a decade. Their manufacture is environmentally friendly and they can be applied to all kinds of materials, such as plastic film, for instance. The trouble is, they only yield a fifth of the electrical energy that silicon solar cells ...
HZB researcher honoured with solar award for his successful research
Prof. Dr. Hans-Werner Schock, department head and spokesman for Solar Energy Research at Helmholtz-Zentrum Berlin (HZB), received the prestigious “Becquerel Prize” at the 25th “European Photovoltaic Solar Energy Conference and Exhibition” in Valencia. The EU Commission honoured the HZB scientist ...
Using “dark channel” fluorescence, scientists can explain how biochemical substances carry out their function
Spectroscopic techniques are among the most important methods by which scientists can look inside materials. They exploit the interaction of light waves with a given sample. Now, using X-ray absorption spectroscopy, researchers from Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) have ...
Novel storage materials of the future will be made out of magnetic films. Researchers at HZB are the first to find out just how fast magnetic particles can be controlled. Christian Stamm and his colleagues at the Helmholtz-Zentrum Berlin für Mate-rialien und Energie (HZB) can look back on six ...
Hidden Symmetry observed for the first Time in Solid State Matter
Researchers from the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB), in cooperation with colleagues from Oxford and Bristol Universities, as well as the Rutherford Appleton Laboratory, UK, have for the first time observed a nanoscale symmetry hidden in solid state matter. They have ...
