22 students from all over the world are working at HZB for eight weeks
The summer programme of HZB has a good reputation among students, and every year HZB receives a lot more applications than it can fund. Now, 22 young people have come from 15 different countries to start their research project in a HZB team. They will present their results at the end of September. [...].
A group of theoretical physicists have devised a mathematical model of two different molecules reacting within so called nanoreactors that act as catalysts. They gained surprising new insights as to what factors promote reactions and how to control and select them. The model is relevant for a wide range of research fields, from biophysics to energy materials. [...].
Lupins not only produce colourful blossoms but also nutritious beans rich in proteins. Just how these plants draw water approaching their roots in soil has now for the first time been observed in three dimensions by a University of Potsdam team at the HZB-BER II neutron source in Berlin. To accomplish this, they worked with the HZB imaging group to improve the temporal resolution of neutron tomography more than onehundred-fold so that a detailed 3D image was generated every ten seconds. This ultrafast neutron tomography is generally suitable as well for analyses of dynamic processes in porous materials. [...].
For the first time an international team realized direct writing of silver nanostructures using an electron beam applied to a substrate. Silver nanostructures have the potential to concentrate visible light at the nanoscale. Potential applications include sensor design to detect extremely small traces of specific molecules, as well as devices for optical information processing. [...].
„The photon is our strength", said Bernd Rech. Since the 1st of May 2017, he has been the acting Scientific Director of HZB. In our new magazine "lichtblick" we spoke with him about his most important duties, the strengths of HZB, and surprises the job held in store. [...].
The University of Potsdam and the Helmholtz-Zentrum Berlin founded the HyPerCells Graduate School just two years ago with focus on metal halide perovskites for solar applications. Now, groups involved in the graduate school have demonstrated perovskite solar cells with record-efficiencies of over 20 percent. This confirms the graduate school is at the forefront of this research in Germany and internationally highly competitive. [...].
A modern information brochure, illustrated throughout with a fusion of photos and sketches, serves as the new business card of HZB. In concise and understandable language, it describes the centre’s most important research focuses, introduces the large-scale facilities and laboratories, and shows why HZB is an internationally attractive place to work. [...].
Rising 18 metres into the air, the nitrogen tank on the Helmholtz-Zentrum Berlin campus in Adlershof was installed on 18 July 2017. It can store up to 80 cubic metres of liquid nitrogen. This nitrogen will be used for pre-cooling the cooling system which is necessary for operating the new energy recovery linear accelerator (bERLinPro). The HZB experts are currently setting up a prototype for testing the potential of this accelerator technology. [...].
The Leibniz Institute for Solid State and Materials Research Dresden (IFW) and Helmholtz-Zentrum Berlin (HZB) have created a Joint Lab for “functional quantum materials” and under its umbrella a Young Investigator Group. [...].
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.
