Molecularly thin water layer, with a hydrogen bonding network different from those in bulk water and ice, has
unique properties and is generally involved in many important processes such as wetting, erosion, atmosphere
chemical reaction, protein folding and biomolecular interaction. Here, we report a new water layer structure at
room temperature, which is found inside nanobubbles by using synchrotron based scanning transmission soft
X-ray microscopy (STXM). The three peaks 535:0, 536:8 and 540:9 eV at O K edge inside the nanobubbles
show a novel characteristics of very thin water layers, which has never been observed before.

Key words: Nanobubble, Soft X-ray absorption, Water layer
