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.
- Confirmed figures for the first time: Investments in BESSY are worthwhile for Berlin and GermanyAn impact analysis by DIW Econ demonstrates the scientific and economic value of BESSY II. Every euro invested yields three euros for Germany and as much as ten euros for the State of Berlin. Furthermore, the study provides an economic forecast for the construction of BESSY III.
The impact analysis was presented on 3 September 2026 to Dr Henry Marx, State Secretary for Science and Research in the Berlin Senate. He supports the investment and is a strong advocate for BESSY III. - Detailed insights at BESSY II into the oxidation processes of copperBefore pure copper oxide builds up, complex superstructures such as ‘29’CuxO, are formed. The new results on the '29' CuxO superstructure have relevance for catalyst research and corrosion protection in the development of safe copper containers for nuclear waste repositories.
- An important step towards detecting fractons in quantum spin liquidsFollowing predictions of the existence of fractons in quantum spin liquids by more general gauge field theories, researchers at HZB succeeded in detecting these quasi-particles also in a quantum solid-state model.
