Intermolecular bond length of ice on Ag(111).
TLDR
Water adsorbed in submonolayer coverage on Ag(111) at 70 K forms hydrogen-bonded networks and scanning tunneling spectroscopy indicates that the bond length within the two-dimensional hydrogen- bonded water layer is shortened.Abstract:
Water adsorbed in submonolayer coverage on Ag(111) at 70 K forms hydrogen-bonded networks. High resolution images in combination with calculation reveal that single protrusions represent a cyclic water hexamer with the intermolecular bond stretched to the silver lattice constant of 0.29 nm. Scanning tunneling spectroscopy indicates that the bond length within the two-dimensional hydrogen-bonded water layer is shortened. The spectra contain further information about the vibrational modes of water molecules.read more

Water adsorption and the wetting of metal surfaces
Andrew Hodgson,Sam Haq +1 more
TL;DR: Water adsorption at metal surfaces is governed by a subtle balance between water-water hydrogen bonding and water-metal interactions, which together determine the stability of the water structures formed as discussed by the authors.

Water adsorption on metal surfaces: A general picture from density functional theory studies
TL;DR: In this article, a density functional theory study of water adsorption on metal surfaces is presented, where the water-surface interaction is dominated by the lone pair-d band coupling through the surface states and a simultaneous enhancement of hydrogen bonding is generally observed in many adsorbed structures.

Ice nanoclusters at hydrophobic metal surfaces.
TL;DR: Aside from achieving unprecedented resolution of the cyclic water hexamer--the so-called smallest piece of ice--this work identifies and explains a hitherto unknown competition between the ability of water molecules to simultaneously bond to a substrate and to accept hydrogen bonds.
