Using molecular dynamics simulation, we show direct evidence of the unexpected phenomenon of "water that does not wet a water monolayer" at room temperature. This phenomenon is attributed to the structure of the water beneath the water droplet, which exhibits an ordered water monolayer. Remarkably, there remains a considerable number of dangling OH bonds in this room temperature water monolayer, in contrast with the absence of dangling OH bonds at cryogenic temperature.
通过分子动力学模拟，我们展示了在室温下“水不润湿水单层”这一意外现象的直接证据。这种现象归因于水滴下方水的结构，其呈现出有序的水单层。值得注意的是，与低温下不存在悬空OH键相比，在这个室温下水单层中仍存在相当数量的悬空OH键。
