Liquid Dynamics at Interfaces — •Michael Vogel — Institut für Physik kondensierter Materie, TU Darmstadt, Hochschulstraße 6, 64289 Darmstadt

Liquids at interfaces are of great importance in nature and technology, for instance, in biological cells, clay minerals, and energy materials. Typically, the dynamics of liquids at interfaces significantly differ from those in the bulk. We combine nuclear magnetic resonance and broadband dielectric spectroscopy with molecular dynamics simulutations to determine the magnitude and range of these interface effects in broad frequency and temperature ranges. It is shown that the free energy landscape imposed by an interface on an adjoining liquid enables a basic understanding of the altered dynamical behavior [1]. It will be discussed that a knowledge of interface effects allows one not only to obtain valuable insights into the properties of confined water and, when avoiding crystallization, the anomalies and vitrification of bulk water [2-4], but also to steer ion transport in electrolyte-host systems for improved lithium-ion battery and proton-exchange membrane materials [5-7].
