From: Microscopic behavior of nano-water droplets on a silica glass surface
The changes in height images (256 pixels) (a–e) and adhesion maps (128 pixels) (f–j) with humidity observed by PFT mode. Peak force set point was 0.5 nN. In (e) and (j), the scan area was shifted due to thermal drift while dry air was brown in. Dotted circles in (g) and (h) indicate lower adhesion area. All scale bars represent 500 nm (scan area of (a) and (f) is smaller than the other images).
