Despite extensive experimental and theoretical investigations9,10,11,12,13,14,15,16,17, the exact atomic structures of ice interfaces remain elusive owing to the vulnerable hydrogen-bonding network and the complicated premelting process. Here we realize atomic-resolution imaging of the basal (0001) ...
The H2O molecule is a versatile molecular building block capable of forming at least eleven different types of four-fold connected crystalline networks through hydrogen bonding1. For a given network topology, the hydrogen-bonded water molecules can either display orientational disorder or order resulting...
bondingH 2OSeveral structural configurations of H O related species adsorbed on the Cu(110) surface have been studied by combining electron stimulated desorption angular distribution (ESDIAD), TDS, LEED and AES measurements, emphasizing local order and some controversial issues. Above ~ 0.1 L ...
The state of molecular orientation in a pure water surface is examined and it is concluded that the surface molecules are almost completely oriented with their negative vertices outward. Because of inter-molecular bonding this orientation decays approximately exponentially beneath the surface, the depth ...
The halides definition is a compound that is formed by the bonding of a halogen atom and an element or radical. There are many different types of halides, such as salts and acids. Some examples of common halides are sodium chloride, or table salt,calcium chloride, which is used to de-ic...
bonding; this causes the water to spread out evenly over the surface, or to wet it. A liquid will wet a surface if the angle at which it makes contact with the surface is more than 90°. The value of thiscontact anglecan be predicted from the properties of the liquid and solid ...

The peak at 3250 cm−1 is related to symmetric H-bonding (they form a strong H-bonding or ice-like network), the peak at 3450 cm−1 is assigned to asymmetric H-bonded water molecules (that cannot form a complete H-bonding network), and the peak at 3610 cm−1 is assigned to ...
