Three-dimensional solvation structure of ethanol on carbonate minerals.

June 2020
Article Synopsis
- Calcite and magnesite are key minerals in the earth's crust that interact with organic molecules, influencing the formation of biominerals.
- Advanced 3D atomic force microscopy (AFM) allows visualization of solid-liquid interfaces at a molecular level, focusing on how ethanol behaves on the surfaces of these carbonates.
- The study shows that ethanol assembles in distinct layers on calcite and magnesite, with the first layer being well-ordered due to specific binding interactions, while subsequent layers are less ordered, reflecting the different chemical contexts.
Solid-liquid interfaces are decisive for a wide range of natural and technological processes, including fields as diverse as geochemistry and environmental science as well as catalysis and corrosion protection. Dynamic atomic force microscopy nowadays provides unparalleled structural insights into solid-liquid interfaces, including the solvation structure above the surface. In contrast, chemical identification of individual interfacial atoms still remains a considerable challenge.
