Kindergarten children are inquisitive and want to know how everything works – and they ask a great deal of questions. On the Germany-wide "Day of Little Researchers" on 19 June, around 100 kids visited the HZB School Labs in Adlershof and Wannsee and investigated the colours of light. [...].
The EU is providing ten million euros in funding for the project CALIPSOplus, submitted by 19 European light sources. The project consortium, of which Helmholtz-Zentrum Berlin is a member, kicked off on May 2017. CALIPSOplus is aimed at promoting the international exchange of scientists and transnational access to the light sources in Europe. Other priorities are to integrate the relatively less active regions of Europe and to initiate research projects with small and mid-sized companies. [...].
Dr. Klaus Habicht has successfully completed the university-level teaching accreditation process in the Faculty of Mathematics and Natural Sciences at the University of Potsdam and received his official university-level teaching qualification for the physics of condensed matter. Habicht has conducted numerous lectures and seminars at the University of Potsdam since 2011, in particular in solid-state physics and methods in neutron research. He heads the Department of Methods for Characterisation of Transport Phenomenon in Energy Materials at the HZB.
Helmholtz-Zentrum Berlin has expanded its series of CoreLabs for energy materials research. In addition to the five established CoreLabs, it has now set up a CoreLab for Quantum Materials. A research team from the HZB Institute for Quantum Phenomena in New Materials is responsible for the CoreLab and its modern equipment. The CoreLab is also open to experimenters from other research institutes. [...].
The Helmholtz-Zentrum Berlin (HZB) is establishing a joint lab together with the Max Planck Society (MPS) to study electrochemical phenomenon at solid/liquid interfaces. The Berlin Joint Lab for Electrochemical Interfaces, or BElChem for short, will employ X-rays from BESSY II to analyse materials for renewable energy production. [...].
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. [...].
Focussed ion beams are highly useful tools for researchers in various disciplines. Samples can be etched in the micro- and nanometre range with them. Modern ion microscopes as well as their complementary methods and techniques are available at the HZB and can be utilised by scientists from universities and institutes from the world over. Now for the first time, the HZB is organising a workshop to introduce these methods and their areas of application. It will take place November 6th and 7th. The deadline for submitting abstracts is June 15.[...].
A paper on X-ray tomography of various types of batteries has been published as a highlight in the exclusive special edition of the Journal of Physics D: Applied Physics. Two groups at the HZB along with a team from Justus Liebig University in Giessen, Germany, contributed to the article. [...].
At the major international photovoltaics exhibition from 31 May to 2 June 2017, Helmholtz-Zentrum Berlin (HZB) will be exhibiting solar energy research projects and presenting opportunities for industrial cooperation in the field of photovoltaics (PV). [...].
Perovskite solar cells have been the big surprise over the last while: inside of only a few years, their efficiency level has been increased from just under 10 % to fully 22 %. There has never been such rapid progress in a new material for solar cells. Scientists around the world are therefore working on this new class of materials. Eva Unger and Steve Albrecht from Helmholtz-Zentrum Berlin (HZB) have evaluated trends in the advancement of perovskite materials in an invited review article in Journal of Materials Chemistry A. They point out what opportunities exist for advancing this class of materials, combining them with other semiconductors, and where limitations lie. [...].
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. [...].
Wir wünschen Ihnen ein frohes Fest und bedanken uns bei allen Kooperations- und Geschäftspartnern für die Zusammenarbeit. Den Leserinnen und Lesern unserer Webseite danken wir für ihre Treue. Wir wünschen Ihnen ein schönes Restjahr und freuen uns auf ein ereignisreiches neues Jahr 2017! Hier geht es zu unserem kleinen Rückblick auf 2016. [...].
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.
