The Helmholtz-Zentrum Berlin (HZB) is launching a major new project through an interdisciplinary architectural competition: an innovative laboratory and office building for expanding joint catalysis research between the HZB and the Max Planck Society (MPS). Catlab is to become an international beacon for catalysis research that will advance the development of novel catalyst materials urgently needed for the energy transition.
The starting signal has been given: the Helmholtz-Zentrum Berlin (HZB) is inviting architecture and engineering firms to enter an architectural design competition for an innovative office and laboratory building for conducting advanced research. The building is to meet federal sustainability criteria.
The new building will greatly broaden and enhance R&D activities in the field of catalysis research at all points of the innovation process. Novel catalyst materials are destined to play a central role in the energy transition by helping replace fossil fuels with both hydrogen and synthetic fuels that can be produced using renewable energy.
It is for this reason that the HZB, the Max Planck Institute for Chemical Energy Conversion, and the Fritz Haber Institute of the MPS are launching the long-term CatLab project in Berlin. The project partners intend to advance the development of energy-related catalysts in CatLab at the HZB-Adlershof site. CatLab’s close proximity to HZB’s BESSY II synchrotron source and its supporting laboratories with their diverse analysis and characterisation methods will produce major synergies.
The building will be located at Magnusstraße 10 in Berlin-Adlershof. An essential feature of the building must be modular expandability. Laboratory and office space should be seamlessly integrated with an Innovation Centre and a data science platform. The laboratory and office requirements that are essential for CatLab should be covered by the initial construction phase. Two further building sections are planned that will provide a location for research activities in the field of Data Science, and establish an anchor for further large industrial collaborations with space for everything from initial exploratory experiments to fully mature applications.
- New method shows how molecular switches are influenced by their neighborsResearchers at Friedrich Schiller University Jena and the Helmholtz Centre Berlin (HZB) have, for the first time, been able to directly observe how the environment surrounding a molecular switch influences its electronic structure. Molecular switches are molecules that can be switched between two states by external influences such as changes in temperature—similar to a switch with the positions »On« and »Off«. Such molecules are being investigated as potential building blocks for future data storage devices or sensor materials. Using magnetic-field-dependent terahertz spectroscopy, the researchers have now, for the first time, been able to distinguish whether neighbouring molecules in a material are in the same or different states. The results have been published in the journal »Angewandte Chemie International Edition«.
- 3D magnetic field experiment at BESSY II takes spintronics a step further(Fe0.63Ni0.3Pd0.07)3P or FNPP is a magnetic material that exhibits complex magnetic structures even at room temperature. This makes the material of interest for spintronics, a field that could enable data processing with significantly lower energy consumption. One potential application is novel magnetic memory devices. However, generating and modifying the desired structures in a controlled manner remains a challenge to date. A new study led by HZB has now taken a step forward in this regard. They demonstrated at the worldwide unique VEKMAG-Station at BESSY II, that a tiny external B-field in the plane of the magnetic patterns is sufficient to change them.
- BESSY II: Evaporated perovskites in tandem solar cells improvedPerovskite-silicon tandem solar cells achieve significantly higher efficiencies than silicon solar cells on their own. One particularly attractive method is co-evaporation of the perovskite precursor molecules on top of the silicon subcell. Scientists at HZB have analysed film growth on the nanoscale at BESSY II and found a new way to improve the quality of the perovskite layer: adding a thin seed layer of caesium chloride between the two sub-cells promotes uniform perovskite growth and suppresses the formation of undesired lead iodide at the interface.
