Aerophilic Debubbling
Bert J. C. Vandereydt, Saurabh Nath, Kripa K. Varanasi
In this letter, we characterize quantitatively the complex phenomenon of debubbling via aerophilic membranes by examining local interactions at the scale of single bubbles. We iden…
Self-Propulsion of Boiling Droplets on Thin Heated Oil Films
Victor Julio Leon, Kripa K. Varanasi
We report on the self-propulsion of boiling droplets which, despite their contact with viscous, immiscible oil films, attain high velocities comparable to those of levitating Leide…
Low-Dimensional Conduction Mechanisms in Highly Conductive and Transparent Conjugated Polymers
Asli Ugur, Ferhat Katmis, Mingda Li +4
Electronic conduction in conjugated polymers is of emerging technological interest for high-performance optoelectronic and thermoelectric devices. A completely new aspect and under…
Sustaining dry surfaces under water
Paul R. Jones, Xiuqing Hao, Eduardo R. Cruz-Chu +9
Rough surfaces immersed under water remain practically dry if the liquid-solid contact is on roughness peaks, while the roughness valleys are filled with gas. Mechanisms that preve…
Sticking around: an up-close look at drop adhesion
Adam T. Paxson, Kripa K. Varanasi
We present a fluid dynamics video showing the adhesion of a drop to a superhydrophobic surface. We use environmental scanning electron microscopy to observe depinning events at the…
Instabilities by ionic bombardment
Seyed Reza Mahmoudi, Sushant Anand, Kazimierz Adamiak +2
This fluid dynamics video is an entry for the Gallery of Fluid Motion of the 66th Annual Meeting of the APS-DFD. This work reveals new types of interfacial instabilities that occur…
