Recently, it has become recognized that, both the physical interactions and the surface morphology have significant impact on the behavior of inter- facial water, including the water structures as well as the wetting properties of the surface. In this review, we summarize some of recent advances in the atom-level pictures of the interfacial water, which exhibits the ordered character on various solid surfaces at room or cryogenic temperature. Special focus has been devoted to the wetting phenomenon of ＂ordered water monolayer that does not completely wet water＂ and the underlying mechanism on model and some real solid surfaces at room temperature. The possible applications of this phenomenon are also discussed.展开更多
