    Three-dimensional graphene: experiment at BESSY II shows that optical properties are tuneable

    An international research team has for the first time investigated the optical properties of three-dimensional nanoporous graphene at the IRIS infrared beamline of the BESSY II electron storage ring. The experiments show that the plasmonic excitations (oscillations of the charge density) in this new material can be precisely controlled by the pore size and by introducing atomic impurities. This could facilitate the manufacture of highly sensitive chemical sensors. [...].

    Better cathode materials for Lithium-Sulphur-Batteries

    A team at the Helmholtz-Zentrum Berlin (HZB) has for the first time fabricated a nanomaterial made from nanoparticles of a titanium oxide compound (Ti4O7) that is characterised by an extremely large surface area, and tested it as a cathode material in lithium-sulphur batteries. The highly porous nanomaterial possesses high storage capacity that remains nearly constant over many charging cycles. [...].

    New Helmholtz Young Investigator Group for electrochemical conversion of carbon dioxide at HZB has started

    Dr. Matthew T. Mayer is setting up a Helmholtz Young Investigator Group in the field of energy materials research at HZB. He investigates how carbon dioxide and water can be converted electrochemically into hydrocarbons such as methane and methanol by using renewable energies. Matthew Mayer will receive 300,000 euros per year over a period of five years for his Young Investigator Group. [...].

    HZB and Freie Universität Berlin establish the joint research group “X-Ray Microscopy” for studying complex cellular processes

    In May this year, the joint research group “X-Ray Microscopy” was launched, combining the expertise of teams led by Prof. Dr. Gerd Schneider (Helmholtz-Zentrum Berlin) and Prof. Dr. Helge Ewers (Freie Universität Berlin). While Ewers’ group contributes its experience in the field of optical microscopy and biological research, the HZB workgroup is responsible for X-ray microscopy at the synchrotron source BESSY II. The two methods help researchers to gain a detailed insight into the processes taking place inside cells. [...].

    HZB Distinguished Lecture on 13 June, 2 pm: Prof. Douglas MacFarlane speaks about “Hydrogen and Ammonia as Energy Carriers and for Energy Storage”

    We cordially invite you to the next “HZB Distinguished Lecture”, which will also be a commemorative event for our friend and colleague, Prof. Leone Spiccia, who passed away in December 2016. Leone held a professorship at Monash University in Australia and was connected with us through Humboldt and Helmholtz International Fellowships. To continue our work in his spirit, a close friend and collaborator of Leone, Prof. Douglas R. MacFarlane from Monash University, will deliver the key lecture on “Hydrogen and Ammonia as Energy Carriers and for Energy Storage – Progress and Perspectives”. [...].

    CIGS Thin-film Solar Modules: HZB invites for workshop

    Global demand for photovoltaic systems is rising sharply. CIGS thin-film modules have become a hot topic for the solar industry. International experts will convene in Stuttgart on May 30, 2017, at the annual IW-CIGSTech workshop to discuss past and potential future technical and industrial advances in this solar technology. The Centre for Solar Energy and Hydrogen Research (ZSW) and the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) are hosting the eighth installment of this workshop, which caters to scientists, engineers and industry specialists.
