Microplastics in soil: Tomography with neutrons and X-rays shows where particles lay in soil

21-Nov-2023 - It really is a problem: Microplastics are everywhere. Now, an HZB and University Potsdam team developed a method that for the first time enables us to precisely localise microplastics in soil. The 3D tomography shows exactly the location of particles and the change in structure of the soil – ...

Watching the charge move in photoexcited molecules

Research opens up the possibility to map the charge flowing inside the molecular landscape

14-Jan-2022 - An international research team led by Markus Gühr’s group at the University of Potsdam performed laser experiments at Deutsches Elektronen-Synchrotron DESY to monitor charge motions in light-excited molecules of thiouracil, which is a modified nucleobase. This class of molecules has a variety of ...

Heat Transport without Heating?

Hot Electrons – a very special form of heat transport in metals

01-Oct-2020 - When heating a platinum layer on nanometer scales, heat can be transferred by hot electrons through a copper layer into a nickel layer without significantly heating the copper in between. This unusual form of heat transport was discovered by a research group around Jan-Etienne Pudell and Matias ...

Nanoscale heat transport under the microscope

27-Aug-2018 - A team of researchers from the Helmholtz-Zentrum Berlin (HZB) and the University of Potsdam has investigated heat transport in a model system comprising nanometre-thin metallic and magnetic layers. Similar systems are candidates for future high-efficiency data storage devices that can be locally ...

Insight into loss processes in perovskite solar cells enables efficiency improvements

03-Aug-2018 - In perovskite solar cells, charge carriers are mainly lost through recombination occurring at interface defect sites. In contrast, recombination at defect sites within the perovskite layer does not limit the performance of the solar cells at present. Teams from the University of Potsdam and the ...

BMBF Project NEMO: Research on New OLED Materials Successfully Concluded

11-Sep-2012 - After three years of intensive research in the field of new solution-processable materials for OLEDs (Organic Light-Emitting Diodes), Merck and ten other partners from industry and academia have successfully concluded the "New materials for OLEDs from solutions" (NEMO) project co-funded by the ...

NEMO Project: 11 Partners Conduct Research on New OLED Materials

German Federal Ministry of Education and Research (BMBF) is supporting the research project “New materials for OLEDs from solutions” (NEMO)

03-Nov-2009 - Merck KGaA announced that it has launched a project called "New materials for OLEDs from solutions" (NEMO) together with partners from industry and science. The objective of this project, which is being co-funded by the German Federal Ministry of Education and Research, is to develop innovative, ...

Investigating micelles, as easy as ABC

08-Apr-2009 - German scientists have used cryogenic transmission electron microscopy to investigate the fluorinated domains within ABC triblock copolymer micelles. Christoph Böttcher from Freie Universität Berlin, André Laschewsky from Universität Potsdam, and their colleagues, have shown using ...
