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. [...].
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. [...].
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. [...].
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. [...].
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”. [...].
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.

Am 2. Mai haben wir Prof. Dr. Anke Kaysser-Pyzalla mit einem Festkolloquium feierlich verabschiedet. Über 200 Mitarbeitende, Gäste und Wegbegleiter aus der Wissenschaft und Politik sind gekommen, um ihr für die hervorragende Zusammenarbeit und ihr großes Engagement für das HZB zu danken. Unser Fotograf hat die schönsten Momente eingefangen. [...].
Following the succession of long-serving Scientific Director Prof. Anke Kaysser-Pyzalla to President of TU Braunschweig, the Supervisory Board of the Helmholtz-Zentrum Berlin has appointed Prof. Bernd Rech as provisional Scientific Director. He assumes this position as of May 1, 2017. Bernd Rech has headed the Institute for Silicon Photovoltaics at the HZB since 2006 and is highly esteemed worldwide as an expert in renewable energies. [...].
Wie sieht die Arbeit von Wissenschaftlerinnen, Ingenieurinnen oder Programmiererinnen aus? Beim Girls‘ Day können Mädchen MINT-Berufe (Mathematik, Informatik, Naturwissenschaften und Technik) kennenlernen, die noch immer nicht besonders beliebt bei den Berufsanfängerinnen sind. Die 70 Plätze für den Girl’s Day an den beiden HZB-Standorten waren schnell vergeben. [...].
An international team has shed light onto interactions between nanodiamonds and water molecules. Experiments at synchrotron sources showed how hydrogenated groups on nanodiamond surfaces change the network of hydrogen bonds in the aqueous environment and may potentially influence the catalytic properties of nanodiamonds, for instance for the production of solar fuels from CO2 and light. [...].

Dr. Matthew T. Mayer from the École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, will be putting together a Helmholtz Young Investigator Group in the field of energy materials research at HZB. He will be researching into how carbon dioxide and water can be converted electrochemically into hydrocarbons such as methane and methanol using renewable energies. Matthew Mayer will receive 300,000 euros per year over a period of five years for establishing and running his Young Investigator Group. [...].
Experiments at BESSY II allow in situ analysis of water management which is helpful for further improvements of fuel cells
HZB scientists have teamed up with partners of 3M Company in order to explore the water management in an alternative proton exchange membrane type, called PFIA. The experiments have been conducted using the infrared facilities of BESSY II synchrotron to reveal how water is retained even at dry conditions in PFIA. The observations explain why PFIA membranes are superior to the widely used NAFIONTM membranes at higher temperatures and low humidity.[...].
Der Klangkünstler Gerriet K. Sharma arbeitet an einem Projekt, zu dem ihn das Ausbauvorhaben BESSY VSR am HZB inspiriert hat. Dabei erschafft er in seinen Kompositionen akustische Skulpturen, die mit einem Ikosaederlautsprecher hörbar werden. Die Technik stellt die Firma Sonible zur Verfügung. Nun hat Sonible ein Video über dieses Projekt produziert, das ab sofort im Netz zu sehen (und zu hören!) ist.
