Special Session 10 HYDROGEN AND WATER-RELATED KINETICS IN MATERIALS (SS10)

This session discusses hydrogen (H) induced phenomena in materials from a wide fundamental perspective, addressing kinetic phenomena both at surfaces and in the interior of solids. We aim to mechanistically understand complex dynamics such as the H transportation across gas/solid interfaces relevant to hydrogen storage, purification, and heterogeneous hydrogenation catalysis. Hydrogen interactions with the defect microstructure and their impact on the mechanical, electronic, and optical properties of (nano-)materials as well as hydrogen isotope retention and exchange in plasma- and radiation-exposed materials receive special attention.

The scientific scope also includes the rich wealth of water interactions with solid surfaces. Discussions aim to bridge the gap between nanoscale processes at water/solid interfaces (dissociation, hydroxylation, H-bond network structures in adsorption layers) and macroscopic phenomena such as wetting, freezing (ice nucleation in sessile water droplets) and frost formation (growth of ice films from H2O vapor on cold surfaces). Both experimentalists and theoreticians are strongly encouraged to participate.

Topics (not exclusive):

• Hydrogen diffusion (surface and bulk)
• H-defect interactions and H-induced defect generation
• H-Permeation and barrier materials
• Embrittlement
• Hydrides – kinetics, thermodynamics, properties
• Hydrogen detection techniques
• Electrochemical interfaces and photocatalytic water splitting
