    Disorder brings out quantum physical talents
    Quantum effects are most noticeable at extremely low temperatures, which limits their usefulness for technical applications. Thin films of MnSb2Te4, however, show new talents due to a small excess of manganese. Apparently, the resulting disorder provides spectacular properties: The material proves to be a topological insulator and is ferromagnetic up to comparatively high temperatures of 50 Kelvin, measurements at BESSY II show.  This makes this class of material suitable for quantum bits, but also for spintronics in general or applications in high-precision metrology.

    Green hydrogen: Why do certain catalysts improve in operation?
    Crystalline cobalt arsenide is a catalyst that generates oxygen during electrolytic water splitting in the production of hydrogen. The material is considered to be a model system for an important group of catalysts whose performance increases under certain conditions in the course of electrolysis. Now a HZB-team headed by Marcel Risch has observed at BESSY II how two simultaneous mechanisms are responsible for this. The catalytic activity of the individual catalysis centres decreases in the course of electrolysis, but at the same time the morphology of the catalyst layer also changes. Under favourable conditions, considerably more catalysis centres come into contact with the electrolyte as a result, so that the overall performance of the catalyst increases.

    Solar hydrogen for Antarctica - study shows advantages of thermally coupled approach
    A team from the Helmholtz-Zentrum Berlin, Ulm University, and Heidelberg University has now investigated how hydrogen can be produced at the South Pole using sunlight, and which method is the most promising. Their conclusion: in extremely cold regions, it can be considerably more efficient to attach the PV modules directly to the electrolyser, i.e. to thermally couple them. This is because the waste heat from the PV modules increases the efficiency of electrolysis in this environment. The results of this study, which has now been published in Energy & Environmental Science, are also relevant for other cold regions on Earth, such as Alaska, Canada, and high mountain regions, for example. In these places, solar hydrogen could replace fossil fuels such as oil and petrol.

So why did bone cells evolve? Why was it so advantageous that most subsequent vertebrates have bone cells?

    Solar cells: Losses made visible on the nanoscale
    Solar cells made of crystalline silicon achieve peak efficiencies, especially in combination with selective contacts made of amorphous silicon (a-Si:H). However, their efficiency is limited by losses in these contact layers. Now, for the first time, a team at Helmholtz-Zentrum Berlin (HZB) and the University of Utah, USA, has experimentally shown how such contact layers generate loss currents on the nanometre scale and what their physical origin is. Using a conductive atomic force microscope, they scanned the solar cell surfaces in ultra-high vacuum and detected tiny, nanometre-sized channels for the detrimental dark currents, which are due to disorder in the a-Si:H layer.

    Accelerator Physics: HF-Couplers for bERLinPro prove resilient
    In synchrotron light sources, an electron accelerator brings electron bunches to almost the speed of light so that they can emit the special "synchrotron light". The electron bunches get their enormous energy and their special shape from a standing electromagnetic alternating field in so-called cavities. With high electron currents, as required in the bERLinPro project, the power needed for the stable excitation of this high-frequency alternating field is enormous. The coupling of this high power is achieved with special antennas, so-called couplers, and is considered a great scientific and technical challenge. Now, a first measurement campaign with optimised couplers at bERLinPro shows that the goal can be achieved.

    CatLab - A beacon for future hydrogen research

    The Helmholtz-Zentrum Berlin and two Max Planck institutes are building a catalysis research platform named CatLab to achieve leaps of innovation in hydrogen research

    Hydrogen as a sustainable fuel source will play a key role in our energy system for the future. Hydrogen-based chemical energy media are needed as long-term storage repositories in the energy system and are crucial for climate-neutral design of industrial processes. The German federal government's National Hydrogen Strategy clearly identifies the great need for research in this area, which will be the foundation for breakthroughs and leaps in innovation. The Helmholtz-Zentrum Berlin (HZB) and two Max Planck institutes – the Fritz Haber Institute (FHI) and the Max Planck Institute for Chemical Energy Conversion (MPI CEC) – are pooling their expertise for this purpose and together with Humboldt Universität zu Berlin they are jointly establishing the CatLab research platform in Berlin. CatLab is intended as a bridge between pure research and industry, and is being funded by the German Federal Ministry of Education and Research (BMBF) with more than 50 million euros. In total, the five-year development project will cost about 100 million euros.
