    Nanodiamonds as photocatalysts

    Diamond nanomaterials are considered hot candidates for low-cost photocatalysts. They can be activated by light and can then accelerate certain reactions between water and CO2 and produce carbon-neutral "solar fuels". The EU project DIACAT has now doped such diamond materials with boron and shown at BESSY II how this could significantly improve the photocatalytic properties. [...].

    Andrea Denker is Professor of "Accelerator Physics for Medicine"

    The Beuth Hochschule für Technik Berlin and the Helmholtz-Zentrum Berlin (HZB) have appointed Prof. Dr. Andrea Denker to the joint professorship "Accelerator Physics for Medicine" as of October 1, 2018. Since 2006, Andrea Denker is head of the department "Proton Therapy" at the HZB, which operates the accelerator for eye tumor therapy. The therapy, offered in cooperation with the Charité - Universitätsmedizin Berlin and the HZB, is unique in Germany. [...].

    Blue phosphorus - mapped and measured for the first time

    Until recently, the existence of "blue" phosphorus was pure theory: Now an HZB team was able to examine samples of blue phosphorus at BESSY II for the first time and confirm via mapping of their electronic band structure that this is actually this exotic phosphorus modification. Blue phosphorus is an interesting candidate for new optoelectronic devices. The results have been published in Nano Letters. [...].

    Collaboration between HZB and the University of Freiburg

    Through a Joint Research Group entitled “Simulation of Energy Materials“ Prof. Joachim Dzubiella of the Albert-Ludwigs-Universität, Freiburg will be able to continue his collaboration with the HZB. The theoretical physicist headed the “Theory and Simulation“ group at the HZB until recently and worked closely together with colleagues conducting experimental research. The new research group will concentrate on electrochemical energy storage and solar fuels. [...].

    Neutrons scan magnetic fields inside samples

    With a newly developed neutron tomography technique, an HZB team has been able to map for the first time magnetic field lines inside materials at the BER II research reactor. Tensorial neutron tomography promises new insights into superconductors, battery electrodes, and other energy-related materials. [...].

    Machine learning helps improving photonic applications

    Photonic nanostructures can be used for many applications, not just in solar cells, but also in optical sensors for cancer markers or other biomolecules. A team at HZB using computer simulations and machine learning has now shown how the design of such nanostructures can be selectively optimised. The results are published in Communications Physics.
