Droplet Drying Patterns on Solid Substrates: From Hydrophilic to Superhydrophobic Contact to Levitating Drops

Figure 5

Evaporation and TPCL pinning as the origin of outward flow inside evaporating sessile droplet [22]. Initial position of the free surface is shown as the dashed line, whereas its new position due to evaporation is shown as the solid line.
