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…
Field-induced shaping of sessile paramagnetic drops
Jennifer Dodoo, Adam A. Stokes
We use the electromagnetic stress tensor to describe the elongation of paramagnetic drops in uniform magnetic fields. This approach implies a linear relationship between the shape…
Apparent Contact Angle and Contact Angle Hysteresis on Liquid Infused Surfaces
Ciro Semprebon, Glen McHale, Halim Kusumaatmaja
We theoretically investigate the apparent contact angle and contact angle hysteresis of a droplet placed on a liquid infused surface. We show that the apparent contact angle is not…
