X-rays from PETRA III reveal weaving of golden coat


Applying nanoscale metal coatings to thin polymer films is of interest for various promising industrial applications, for example as a means of increasing the efficiency of organic solar cells. The properties of the metal coatings need to be precisely adjusted, depending on the application in question. At DESY, scientists have now studied in real time how the structure of a fine gold coating produced by ...

X-ray pulses reveal structure of viral cocoon


An international team, including scientists from DESY, has used high-intensity X-ray pulses to determine the structure of the crystalline protein envelope of an insect virus. Their analysis reveals the fine details of the building blocks that make up the viral cocoon down to a scale of 0.2 nanometres (millionths of a millimetre) – approaching atom-scale resolution. The tiny viruses with their ...

Under pressure: Heliums forms stable compound


Using high pressure, an international team of researchers has produced a stable sodium-helium crystal. In experiments partly carried out at PETRA III, they  were able to confirm the compound. This discovery comes as a surprise as Helium does not react with other elements under normal conditions. The scientists around Artem R. Oganov of the Skolkovo Institute of Science and Technology (Skoltech) in ...

Researchers unravel dynamics of electron clouds


A US-German research team, including scientists from DESY,  has elucidated the ultra-fast dynamics of electron clouds in xenon atoms. Using attosecond technology, the scientists around Stephen R. Leone from the University of California in Berkeley were able to measure the reactions of the electrons to the strong field of an intense laser pulse in real time. Quantum mechanical modelling of the process ...

DFG funds interdisciplinary research project with two million euros


The research unit “Matter Under Planetary Interior Conditions”, led by the University of Rostock and including scientists from DESY will find out more about exoplanets in the framework of a grant funded by the German Research Foundation (DFG). With the help of telescopes on Earth and in space, several thousand planets outside of our solar system have been discovered since 1996. Observation ...

X-ray vision reveals new crystal structure in “gum metal”


Scientists from the Max-Planck-Institut für Eisenforschung (MPIE) have observed a new phase transformation in a titanium alloy at the X-ray source PETRA III at DESY. The mechanism they discovered could further our understanding of some surprising properties of certain alloys and be used to develop new materials. The team around main author Jian Zhang of the MPIE in Düsseldorf presents its ...

Meeting for users concludes with record participation


The joint users' meeting of the DESY research light sources and the X-ray laser European XFEL attracted more participants than ever before. Around 1,100 scientists from more than 70 institutions from 30 countries had registered for this year's meeting to discuss research possibilities at the bright X-ray light sources in Hamburg. With the X-ray lasers FLASH and European XFEL as well as the X-ray ...

Foundation for new type of solar cell


An interdisciplinary team of researchers, also from DESY, has laid the foundations for an entirely new type of photovoltaic cell. In this new method, infrared radiation is converted into electrical energy using a different mechanism from that found in conventional solar cells. The mechanism behind the new solid-state solar cell made of the mineral perovskite relies on so-called polaron excitations, which ...

X-ray study throws light on key process for production


A Swedish-German team of researchers has cleared up a key process for the artificial production of silk. With the help of the intense X-rays from  PETRA III, DESY's research light source, the scientists could watch just how small protein pieces, called nanofibrils, lock together to form a fibre. Surprisingly, the best fibres are not formed by the longest protein pieces. Instead, the strongest ...

First attosecond timing in a kilometre-wide laser-microwave network


Scientists at DESY have set up the world's most precise ‘metronome’ for a kilometre-wide network. The timing system synchronizes a 4.7-kilometer-long laser-microwave network with 950 attoseconds precision. An attosecond is a quintillionth of a second, or a millionth of a millionth of a millionth of a second. Such installations can provide the beat for recording ultrafast X-ray snapshots of ...
