Recommended reading: Bunsen magazine with focus on molecular water research
Water not only has some well-known anomalies, but is still full of surprises. The first issue 2023 of the Bunsen Magazine is dedicated to molecular water research, from the ocean to processes in electrolysis. The issue presents contributions from researchers cooperating within the framework of a European research initiative in the "Centre for Molecular Water Science" (CMWS). A team at HZB presents results from the synchrotron spectroscopy of water. Modern X-ray sources can be used to study molecular and electronic processes in water in detail.
With their report on "Local and collective properties of water", Annette Pietzsch, Robert Seidel and Alexander Föhlisch from HZB describe insights on the nature of water, gained with synchrotron spectroscopy at BESSY II. For example, water, which is normally a perfect insulator, can become metallic under certain conditions.
Other contributions explain the challenges of desalinating seawater, processes in electrolysis or structures in ice on the nanoscale.
These insights help in the design of even better climate models, in environmental research, the design of drugs and vaccines, but also in the development of novel catalysts for green hydrogen or other important technologies.
- MAX IV and BESSY II initiate new collaboration to advance materials scienceSwedish national synchrotron laboratory MAX IV and Helmholtz-Zentrum Berlin (HZB) with BESSY II light source jointly announce the signing of a 5-year Cooperation Agreement. The new agreement establishes a framework to strengthen cooperation for operational and technological development in the highlighted fields of accelerator research and development, beamlines and optics, endstations and sample environments as well as digitalisation and data science.
- AI in Chemistry: Study Highlights Strengths and WeaknessesHow well does artificial intelligence perform compared to human experts? A research team at HIPOLE Jena set out to answer this question in the field of chemistry. Using a newly developed evaluation method called “ChemBench,” the researchers compared the performance of modern language models such as GPT-4 with that of experienced chemists.
- Green hydrogen: MXene boosts the effectiveness of catalystsMXenes are adept at hosting catalytically active particles. This property can be exploited to create more potent catalyst materials that significantly accelerate and enhance the oxygen evolution reaction, which is one of the bottlenecks in the production of green hydrogen via electrolysis using solar or wind power. A detailed study by an international team led by HZB chemist Michelle Browne shows the potential of these new materials for future large-scale applications. The study is published in Advanced Functional Materials.
