(592c) Water On Surfaces: How the Molecular Structure Determines Hydrodynamic Slip

Understanding and predicting the behavior of water, especially in contact with various surfaces, is a scientific challenge that continues to attract enormous interest. It is becoming popular to determine the relationship between atomic properties of water molecules near a solid interface to macroscopic observables, including for example the measured contact angle. In this presentation we will describe how the distribution of water molecules within the first hydration layer dictates hydrodynamic slip. Equilibrium and non-equilibrium molecular dynamics simulations are employed. The results will be discussed towards elucidating the mechanism responsible for liquid slip vs. no-slip at the surface.
