On 16 May 2022, HZB received a delegation from the Brazilian Ministry of Science, Technology and Innovation (MCTI). Vice-Minister of Science Sergio Freitas de Almeida was visibly impressed by the many research activities being done at HZB to drive the transition to a climate-neutral energy supply in society forward.
The delegation visited HZB in advance of the 9th German–Brazilian Dialogue on Science, taking place from 17 to 20 May 2022 in Berlin. Vice-Minister Sergio Freitas de Almeida was accompanied by State Secretaries José Gontijo (Entrepreneurship and Innovation) and Marcelo Morales (Research and Scientific Training) along with other government representatives.
The delegation toured the X-ray source BESSY II which, of course, is also available to Brazilian researchers. The energy research laboratory EMIL and the new research platform for catalysis research CatLab were also on the tour programme. New catalysts are a key component for producing green hydrogen efficiently and cost-effectively, as well as alternative, sustainable fuels and green raw materials for the chemical industry. The interest of the Brazilian delegation in the development of hydrogen technologies was very high. They were also very interested in cooperation between their light source SIRIUS in Campinas (Sao Paolo) and BESSY II in Berlin.
The discussions with representatives of the Brazilian government inspired all participants to strengthen cooperation in the area of research.
- X-ray analysis reveals overpainted fascist symbolsErich Mercker was a successful painter during the Nazi era and in the years that followed. After 1945, he covered up Nazi symbols in at least one of his paintings. With an interdisciplinary team, physicist Dr Ioanna Mantouvalou reports on this study in the Nature Journal Heritage Science.
- Magnon momentum microscopy: A new window into nanoscale spin-wavesAn international team lead by the Max Born Institute has developed a new type of momentum microscopy to image magnons — the quanta of collectively excited spins — directly in two-dimensional reciprocal space using soft X-rays. Measurements have taken place at BESSY II and PETRA III, first author ist the HZB physicist Steffen Wittrock. Owing to its remarkable sensitivity, simplicity, and access to nanometer-scale wavelengths, this novel technique establishes a powerful and versatile platform for exploring nonlinear magnon interactions, which are promising for future computing schemes.
- Magnetic field during catalyst synthesis triples ammonia yieldApplying an external magnetic field during the synthesis of CoFe₂O₄ electrocatalysts triples the ammonia yield during electrocatalytic conversion. The magnetic field alters the surface states of the spinel oxide thin films, making catalytically active sites more accessible. In the journal 'Advanced Functional Materials', a team led by Marcel Risch at HZB and Sanjay Mathur at University of Cologne demonstrates a scalable strategy for developing next-generation electrocatalysts for efficient and sustainable chemical production.
