Quasi-stabilized hydration layers on muscovite mica under a thin water film grown from humid air

Abstract The interfaces between solids and water films in air play fundamental roles in physicochemical phenomena, biological functions, and nano-fabrication. Though the properties of the interfaces have been considered to be irrelevant to the water film thickness, we found distinctive mechanical fe...
