HIGHLIGHTS
- who: Rafsan Rabbi from the (UNIVERSITY) have published the research: Droplet lift-off from hydrophobic surfaces from impact with soft-hydrogel spheres, in the Journal: (JOURNAL)
- what: The authors investigate a deviation from this conventional pattern and present a binary impact mechanism where the sessile droplet rebounds off of the superhydrophobic surface in the expansion stage. The authors propose that this large sphere deformation applies a downward force on the droplet enabling the droplet to lift-off. The authors propose a modifed Ma* number to quantify different regimes, and propose two conditions for lift-off . . .
