Spontaneous Coulomb fissions of drops on lubricated surfaces
Marcus Lin, Peng Zhang, Aaron D. Ratschow +3
Charged water drops are more widespread than commonly acknowledged. For example, raindrops typically carry charges of order Q ~ 1 pC, while routine pipetting in the laboratory prod…
Unraveling friction forces of droplets on a non-wetting surface
Abhijit Kumar Kushwaha, Sankara Arunachalam, Ville Jokinen +2
This paper explores the friction forces encountered by droplets on non-wetting surfaces, specifically focusing on superhydrophobic and superheated substrates. Employing a combinati…
Directional Wetting of Submerged Gas-entrapping Microtextures
Sankara Narayana Moorthi Arunachalam, Himanshu Mishra
Numerous natural and industrial processes entail the spontaneous entrapment of gas/air as rough/patterned surfaces are submerged under water. As the wetting transitions ensue, the…
Coating-free Underwater Breathing via Biomimicry
Sankara Narayana Moorthi Arunachalam, Muhammad Subkhi Sadullah, Himanshu Mishra
Numerous natural and engineering scenarios necessitate entrapment of air pockets or bubbles on submerged surfaces, e.g., aquatic insects, smartphones, and membranes for separation…
Emergent collective motion of self-propelled condensate droplets
Marcus Lin, Philseok Kim, Sankara Arunachalam +5
Recently, there is much interest in droplet condensation on soft or liquid/liquid-like substrates. Droplets can deform soft and liquid interfaces resulting in a wealth of phenomena…
General Predictive Framework for Droplet Detachment Force
Muhammad Subkhi Sadullah, Yinfeng Xu, Sankara Arunachalam +1
Liquid droplets hanging from solid surfaces are commonplace, but their physics is complex. Examples include dew or raindrops hanging onto wires or droplets accumulating onto a cove…
Unexpected Suppression of Leidenfrost Phenomenon on Superhydrophobic Surfaces
Meng Shi, Ratul Das, Sankara Arunachalam +1
The Leidenfrost phenomenon entails the levitation of a liquid droplet over a superheated surface, cushioned by its vapor layer. For water, superhydrophobic surfaces are believed to…
