Dr. Michelle Browne establishes her own young investigator group at the HZB . Starting in August, the group is co-funded by the Helmholtz Association for the next five years. The electrochemist from Ireland concentrates on electrolytically active novel material systems and wants to develop next-generation electrocatalysts, for example hydrogen production. At HZB she will find the perfect environment to conduct her research.
Michelle Browne received her PhD in 2016 from the University of Dublin, Trinity College Dublin (TCD), Ireland. She held research fellow positions at universities in Belfast, Prague, and Dublin. She has received prestigious fellowships and awards, for example the Marie Skłodowska-Curie Individual Fellowship, L’Oreal UNESCO Rising Talent UK & Ireland Fellowship and the Clara Immerwahr Award.
Her research focuses on the synthesis of novel catalytically active materials such as transition metal oxides and MXenes. She aims to characterise and optimise these material systems in order to develop next-generation electrolyzer materials that can also be upscaled for industrial use, in order to produce green hydrogen.
Electrocatalysis: Synthesis to Devices
Michelle Browne's research project fits perfectly with the research projects already underway at the Institute for Solar Fuels and within CatLab. "At HZB, I have a wide variety of investigation methods at my disposal, from scanning electron microscopy to the various instruments at BESSY II, which also allow operando analyses," she says.
Michelle Browne's affiliation with the Technische Universität Berlin in the Institute of Chemistry is planned. Starting in the fall, Browne will recruit postdocs and PhD students to join her team.
- Helmholtz Institute for Polymers in Energy Applications (HIPOLE Jena) InauguratedOn June 17, 2024, the Helmholtz Institute for Polymers in Energy Applications (HIPOLE Jena) was officially inaugurated in Jena in the presence of Wolfgang Tiefensee, Minister for Economy, Science, and Digital Society of the Free State of Thuringia. The institute was founded by the Helmholtz Center Berlin for Materials and Energy (HZB) in cooperation with the Friedrich Schiller University Jena. It is dedicated to developing sustainable polymer materials for energy technologies, which are expected to play a key role in the energy transition and support Germany’s goal of becoming climate-neutral by 2045.
- “Research and development in times of war: not only possible, but crucial!”The Ukraine Recovery Conference took place in Berlin on 11 and 12 June. On a side-event representatives from Helmholtz, Fraunhofer and Leibniz discussed how research can contribute to the sustainable reconstruction of Ukraine.
In this interview, Bernd Rech, scientific director at HZB, talks about the importance of research during the war and projects such as Green Deal Ukraina. - MXenes for energy storage: Chemical imaging more than just surface deepA new method in spectromicroscopy significantly improves the study of chemical reactions at the nanoscale, both on surfaces and inside layered materials. Scanning X-ray microscopy (SXM) at MAXYMUS beamline of BESSY II enables the investigation of chemical species adsorbed on the top layer (surface) or intercalated within the MXene electrode (bulk) with high chemical sensitivity. The method was developed by a HZB team led by Dr. Tristan Petit. The scientists demonstrated among others first SXM on MXene flakes, a material used as electrode in lithium-ion batteries.
