    Neutron data help to reveal “spooky” entanglement in quantum magnets
    Using data from the British neutron source ISIS from the year 2000, research teams have now demonstrated the viability of a “quantum entanglement witness” capable of proving the presence of entanglement between magnetic particles, or spins, in a quantum material. A team from HZB led by Prof. Bella Lake was also involved in the analysis.

    "Green" chemistry: BESSY II sheds light on mechanochemical synthesis
    In mechanochemistry, reagents are finely ground and mixed so that they combine to form the desired product, even without need for solvent. By eliminating solvent, this technology promises to contribute significantly towards ‘green’ and environmentally benign chemical manufacture in the future. However, there are still major gaps in understanding the key processes that occur during mechanical treatment and reaction. A team led by the Federal Institute for Materials Research (BAM) has now developed a method at BESSY II to observe these processes in situ with X-ray scattering.

    Beam diagnostics for future laser wakefield accelerators
    For decades, particle accelerators have been getting bigger and bigger. In the meantime, ring accelerators with circumferences of many kilometres have reached a practical limit. Linear accelerators in the GHz range also require very long construction lengths. For some years now, however, an alternative is explored: "tabletop particle accelerators" based on the laser excitation of charge waves in plasmas (laser wakefield). Such compact particle accelerators would be particularly interesting for future accelerator-driven light sources, but are also being investigated for high-energy physics. A team from Helmholtz-Zentrum Berlin (HZB) and the Physikalisch-Technische Bundesanstalt (PTB) has developed a method to precisely measure the cross-section of electron bunches accelerated in this way.  This brings applications of these new accelerator technologies for medicine and research closer.

    BESSY II: universal mechanism of regulation in plant cells discovered
    In pioneering work, a German-Japanese research team at BESSY II has been able to determine the 3D structure of a metalloprotein that plays an important role as a catalyst in all plant cells. This involves the DYW deaminase domain of what is referred to as the RNA editosome. The DYW domain alters messenger RNA nucleotides in chloroplasts and mitochondria and contains a zinc ion whose activity is controlled by a very unusual mechanism. The team has now been able to describe this mechanism in detail for the first time. Their study, published in Nature Catalysis, is considered a breakthrough in the field of plant molecular biology and has far-reaching implications for bioengineering.

    Green hydrogen: "Rust" as a photoanode and its limits
    Metal oxides such as rust are intriguing photoelectrode materials for the production of green hydrogen with sunlight. They are cheap and abundant, but in spite of decades of research, progress has been limited. A team at HZB, together with partners from Ben Gurion University and the Technion, Israel, has now analysed the optoelectronic properties of rust (haematite) and other metal oxides in unprecedented detail. Their results show that the maximum achievable efficiency of haematite electrodes is significantly lower than previously assumed. The study demonstrates ways to assess new photoelectrode materials more realistically.

    Tomography brings insights into the early evolution of bones
    Modern biology considers bone cells (osteocytes) as essential for bone development and health. However, when bone initially evolved some 400-million years ago, it did not contain bone cells. So why did bone cells evolve? Why was it so advantageous that most subsequent vertebrates have bone cells? A joint team of palaeontologists at Berlin’s natural history museum has now for the first time analysed these structures in 400 million-year-old fossils of marine life at unprecedentedly high resolution and in 3D. To be able to view these structures, tomography experts at the Helmholtz-Zentrum Berlin (HZB) examined the samples under the focussed ion beam of a scanning electron microscope to calculate 3D images from the data, achieving resolutions in the nanometre range using technology that was initially developed to study battery corrosion.
