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…
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…
Apparent Contact Angle of Droplets on Liquid Infused Surfaces: Geometric Interpretation
Ciro Semprebon, Muhammad Subkhi Sadullah, Glen McHale +1
We theoretically investigate the apparent contact angle of droplets on liquid infused surfaces as a function of the relative size of the wetting ridge and the deposited droplet. We…
Factors Controlling the Pinning Force of Liquid Droplets on Liquid Infused Surfaces
Muhammad Subkhi Sadullah, Jack R. Panter, Halim Kusumaatmaja
Liquid infused surfaces with partially wetting lubricants have recently been exploited for numerous intriguing applications, such as for droplet manipulation, droplet collection an…
Bidirectional Motion of Droplets on Gradient Liquid Infused Surfaces
Muhammad Subkhi Sadullah, Gaby Launay, Jayne Parle +5
We demonstrate spontaneous bidirectional motion of droplets on liquid infused surfaces in the presence of a topographical gradient, in which the droplets can move either toward the…
Self-Propelled Droplet Transport on Shaped-Liquid Surfaces
Gaby Launay, Muhammad Subkhi Sadullah, Glen McHale +3
The transport of small quantities of liquid on a solid surface is inhibited by the resistance to motion caused by the contact between the liquid and the solid. To overcome such res…
Drop dynamics on Liquid Infused Surfaces: The Role of the Wetting Ridge
Muhammad Subkhi Sadullah, Ciro Semprebon, Halim Kusumaatmaja
We employ a free energy lattice Boltzmann method to study the dynamics of a ternary fluid system consisting of a liquid drop driven by a body force across a regularly textured subs…
