MPG lecture for natural sciences | Molecular View of Water and Ice Interfaces

by Prof. Mischa Bonn (Max Planck Institute for Polymer Research)

Wednesday 4 Dec 2019, 15:00 → 16:30 Europe/Berlin

Auditorium (DESY, Bldg 5)

Water and ice surfaces and interfaces are ubiquitous, not just in nature, but also in many technological applications. Water is a rather unique liquid, owing to its strong intermolecular interactions: strong hydrogen bonds hold water molecules together. At the surface of water and ice, the water hydrogen-bonded network is abruptly interrupted, conferring distinct properties on the interface, compared to bulk. I will present some challenges (“how can we study the ~1 monolayer of water molecules that is in direct contact with the other phase, and distinguish this ~Angstrom-thin layer from the bulk?”) and progress in the study of interfacial water. I will specifically address the interaction of water with charged interfaces, and attempt to explain why ice is slippery.
