Ordered water monolayer at room temperature

The wetting behavior of surfaces has a fundamental bearing on various phenomena that arise in physics, chemistry, biology, nanoscience, and nanotechnology. Water confined on the nanometer scale, usually exhibits behavior different from bulk systems and significantly depends on the structure of nanoscale systems. Here, we review some of our recent progress on the effect of ordered water monolayers on wetting, which serves as direct evidence for the unexpected phenomenon of water that does not completely wet water'' at room temperature. The mechanism underlying this novel phenomenon is presented. Further, we discuss the recent experimental observations and applications related to those findings.
