Fig. 3: Time evolution of descending drops.
From: Oscillatory motion of viscoelastic drops on slippery lubricated surfaces
a Time evolution of the front position of the contact line xf of drops of different solutions having volume Ω = 30 μL deposited on lubricated surfaces inclined by α = 30° (α = 15° for the polyacrylamide PAA18 and Xanthan solutions). b–i Time evolution of the instantaneous deviation δx of the front and rear contact points of drops of different solutions from the average linear trends reported in (a). Solid (open) symbols refer to the front (rear) contact point. The vertical dashed lines in panel (f), labelled from (i) to (iv), highlight the time instants corresponding to the snapshots in Fig. 2c.
