    The miracle material graphene: convex as a chesterfield

    Graphene possesses extreme properties and can be utilised in many ways. Even the spins of graphene can be controlled through use of a trick. This had already been demonstrated by a HZB team some time ago: the physicists applied a layer of graphene onto a nickel substrate and introduced atoms of gold in between (intercalation). The scientists now show why this has such a dramatic influence on the spins in a paper published in 2D Materials. As a result, graphene can also be considered as a material for future information technologies that are based on processing spins as units of information.

    Breakthrough at EMIL: First undulator radiation in the CAT experiment

    When the EMIL laboratory (Energy-Materials In-Situ Laboratory Berlin) was ceremoniously inaugurated a year ago in the presence of Federal Minister for Research Johanna Wanka, it was a major milestone for energy materials research at HZB. Ever since, HZB has been building the system that will bring X-ray beams all the way from BESSY II to the EMIL apparatuses. Until the BESSY light is fully available, the scientists have been working with X-rays from a conventional laboratory source. Now, the beamline operators have succeeded in guiding the X-rays from Undulator UE48 in the BESSY II experimental hall to the CAT experiment in the EMIL laboratory. There, it was quantitatively measured using a focus measuring chamber. [...].

    Solar hydrogen production by artificial leafs:

    Scientists analysed how a special treatment improves cheap metal oxide photoelectrodes

    Metal oxides are promising candidates for cheap and stable photoelectrodes for solar water splitting, producing hydrogen with sunlight. Unfortunately, metal oxides are not highly efficient in this job. A known remedy is a treatment with heat and hydrogen. An international collaboration has now discovered why this treatment works so well, paving the way to more efficient and cheap devices for solar hydrogen production. [...].

    A research team at Helmholtz-Zentrum Berlin (HZB) has shown for the first time how laser modulation of magnetic properties in materials is influenced by thermal effects and how the process occurs under moderate experimental parameters. At the same time, the scientists discovered a previously unknown dependence on the thickness of the magnetic layer. This is an important clue for our theoretical understanding of optically controlled magnetic data storage media. The findings are published today in the journal Scientific Reports. [...].

    User research at BER II: Lupin roots observed in the act of catching water from soil – so far too quick for 3D views

    Lupins not only produce colourful blossoms but also nutritious beans rich in proteins. Just how these plants draw water approaching their roots in soil has now for the first time been observed in three dimensions by a University of Potsdam team at the HZB-BER II neutron source in Berlin. To accomplish this, they worked with the HZB imaging group to improve the temporal resolution of neutron tomography more than onehundred-fold so that a detailed 3D image was generated every ten seconds. This ultrafast neutron tomography is generally suitable as well for analyses of dynamic processes in porous materials. [...].

    Cutting-edge research in Berlin: BESSY II light source to be equipped with new features and capabilities

    With the transformation of the BESSY II light source into a variable-pulse-length storage ring, Berlin will become even more attractive as a location for science to researchers from the world over

    The Senate of the Helmholtz Association resolved on June 1st, 2017 to support the transformation of BESSY II into a variable-pulse-length storage ring (BESSY-VSR). The Helmholtz Association will provide funding of 11.9 million euros for the upgrade project, with 10.1 million euros provided by internal resources of its operator, the Helmholtz-Zentrum Berlin (HZB). Following the upgrade, BESSY-VSR will be the first synchrotron light source in the world to deliver brilliant X-ray pulses with user-selectable durations: short and long light pulses will be simultaneously produced in the same ring. This will open up new opportunities for researchers, including new studies on energy materials that contribute to sustainable energy supplies and storage. [...].

    Finding and understanding low cost catalysts: it all comes down to the iron

    A team has investigated more than one hundred iron-nickel catalysts containing various admixtures of chromium. At BESSY II, they also analysed the configurations of the electrons in the individual elements. The team showed that an increasing proportion of chromium primarily influences the energy levels of the iron electrons, which are important for the catalytic effect. The results of this high-throughput study will assist the knowledge-based search for better specific catalysts. [...].

    How to increase efficiencies of ultrathin CIGSe solar cells

    Nanoparticles at the back help harvesting the light.

    Ultrathin CIGSe solar cells need much less rare earth elements and energy for production. Unfortunately, they are much less efficient too. Now a team at HZB together with a group in the Netherlands has shown how to prevent the absorption loss of ultrathin CIGSe cells. They designed  nanostructured  back contacts for light trapping and could achieve a new record value of the the short circuit current density, reaching nearly the best values for thicker CIGSe-cells.  [...].
