O 5: Focus Session: Mineral-water interfaces I
Monday, March 9, 2026, 10:30–12:30, HSZ/0403
The Focus Session discusses recent advances in the understanding of mineral-water interfaces. These interfaces are ubiquitous in nature, host of many geological and biological processes, intimately linked to the global carbon cycle, and therefore highly relevant for Earth*s climate. For example, silicate weathering removes carbon dioxide from the atmosphere on geological timescales, acting as a stabilizing feedback mechanism since weathering rates increase with temperature. In the oceans, carbonates dissolve and precipitate in response to changing atmospheric carbon dioxide concentrations, thus far mitigating part of the anthropogenic impact of CO2 emissions. In addition, numerous industrial and technological processes involve mineral-water interfaces, including seawater desalination, scaling and incrustation prevention, as well as various biochemical applications. However, and despite their importance, many fundamental aspects of mineral-water interfaces remain poorly understood, including water binding and diffusion, structure formation, ice nucleation, growth, or desorption.
This DPG Focus Session will address these aspects at the molecular level, elucidating fundamental processes involving both single water molecules and bulk water in contact with mineral surfaces. The session brings together scientists investigating mineral-water systems under ultrahigh vacuum conditions as well as at mineral-water interfaces in bulk aqueous environments. We aim for a balanced Session with contribution from both renowned experts and young investigators active in the field.
Organized by Philipp Rahe (U Osnabrück), Angelika Kühnle (U Bielefeld), Jan Balajka (TU Vienna), Wolf Gero Schmidt (U Paderborn).
