On Thursday, 12 October 2023, Michelle Browne received a prestigious award in Hamburg: The "Curious Mind Award" in the category "Mobility, Energy and Sustainable Business" by manager magazin.
The young chemist is researching novel material systems as catalysts for green hydrogen through electrolysis. Among other achievements, Michelle Browne has designed a larger electrolysis cell that can be produced using a 3D printer. This device allows to examine many processes under more realistic conditions than with the tiny “shot-glass” cells commonly used in the laboratory. The print data is available in open access, benefiting research groups worldwide.
Michelle Browne completed her PhD at Trinity College in Dublin, Ireland. After postdoctoral positions in Belfast, Prague and London, she is now building up her own research group at Helmholtz-Zentrum Berlin. For her innovative research, she was also awarded the “L’Oréal-and Unesco Women in Science – Rising talents” Award 2021. manager magazin will publish a feature and a video on Michelle Browne and her work.
- Porous Radical Organic framework improves lithium-sulphur batteriesA team led by Prof. Yan Lu, HZB, and Prof. Arne Thomas, Technical University of Berlin, has developed a material that enhances the capacity and stability of lithium-sulphur batteries. The material is based on polymers that form a framework with open pores (known as radical-cationic covalent organic frameworks or COFs). Catalytically accelerated reactions take place in these pores, firmly trapping polysulphides, which would shorten the battery life. Some of the experimental analyses were conducted at the BAMline at BESSY II.
- Metallic nanocatalysts: what really happens during catalysisUsing a combination of spectromicroscopy at BESSY II and microscopic analyses at DESY's NanoLab, a team has gained new insights into the chemical behaviour of nanocatalysts during catalysis. The nanoparticles consisted of a platinum core with a rhodium shell. This configuration allows a better understanding of structural changes in, for example, rhodium-platinum catalysts for emission control. The results show that under typical catalytic conditions, some of the rhodium in the shell can diffuse into the interior of the nanoparticles. However, most of it remains on the surface and oxidises. This process is strongly dependent on the surface orientation of the nanoparticle facets.
