DAPHNE - Data for Photon and Neutron Experiments
© Grafik: DFG
Data in the petabyte range are produced annually at large-scale facilities. This research data must be stored for at least ten years. Now 19 scientific institutions in Germany, among them HZB, aim to develop common standards for software, data exchange and data repositories to make research data permanently available. The DAPHNE4NFDI project will be funded over the next five years as part of the National Research Data Infrastructure and is coordinated by DESY.
In research data management the FAIR criteria do apply: Data must be Findable, Accessible, Interoperable and Reusable, for humans as well as for algorithms. The connection to artificial intelligence methods or machine learning are also part of the task.
HZB is contributing its expertise in research data management to the project. HZB has already participated in European projects such as PaNDATA, from which the data repository ICAT emerged, as well as in Helmholtz initiatives, which resulted in the HMC Hub matter being located at HZB.
- HZB patent for semiconductor characterisation goes into serial productionAn HZB team has developed an innovative monochromator that is now being produced and marketed by a company. The device makes it possible to quickly and continuously measure the optoelectronic properties of semiconductor materials with high precision over a broad spectral range from the near infrared to the deep ultraviolet. Stray light is efficiently suppressed. This innovation is of interest for the development of new materials and can also be used to better control industrial processes.
- BESSY II: Heterostructures for SpintronicsSpintronic devices work with spin textures caused by quantum-physical interactions. A Spanish-German collaboration has now studied graphene-cobalt-iridium heterostructures at BESSY II. The results show how two desired quantum-physical effects reinforce each other in these heterostructures. This could lead to new spintronic devices based on these materials.
- Green hydrogen: MXenes shows talent as catalyst for oxygen evolutionThe MXene class of materials has many talents. An international team led by HZB chemist Michelle Browne has now demonstrated that MXenes, properly functionalised, are excellent catalysts for the oxygen evolution reaction in electrolytic water splitting. They are more stable and efficient than the best metal oxide catalysts currently available. The team is now extensively characterising these MXene catalysts for water splitting at the Berlin X-ray source BESSY II and Soleil Synchrotron in France.
