WebFeb 15, 2024 · Design strategy and fabrication. In this paper, we designed a heterogenously-wetting anti-fingerprint glass surface, achieved by creating nanopillars with remarkable wettability contrast. The tops are oleophilic while the sidewalls are oleophobic. An example of these heterogenous nanopillars is shown in Fig. 1a. WebApr 1, 2014 · The phenomenon is also an example of the wetting–dewetting dynamic. When red wine is poured into a clean wine glass, the wine is observed to be initially driven by the capillarity to climb up and wet the glass wall, forming a wet film. The layer of wine-wetted glass that is exposed to air loses its alcohol by evaporation.

On the other hand, if the angle is below than 90° the material is wetting the surface (see Fig. 1.22). The angle is determined by properties of the liquid, gas medium and the solid surface. redlion wifi sled
