Droplet Migration on Conical Fibers
Clementine Fournier, Carmen Lee, Rafael Schulman +2
The spontaneous migration of droplets on conical fibers is studied experimentally by depositing silicone oil droplets onto conical glass fibers. Their motion is recorded using opti…
Droplets capped with an elastic film can be round, elliptical, or nearly square
Rafael D. Schulman, Kari Dalnoki-Veress
We present experiments which show that the partial wetting of droplets capped by taut elastic films is highly tunable. Adjusting the tension allows the contact angle and droplet mo…
Liquid dewetting under a thin elastic film
Rafael D. Schulman, John F. Niven, Michiel A. Hack +2
We study the dewetting of liquid films capped by a thin elastomeric layer. When the tension in the elastomer is isotropic, circular holes grow at a rate which decreases with increa…
Surface energy of strained amorphous solids
Rafael D. Schulman, Miguel Trejo, Thomas Salez +2
Surface stress and surface energy are fundamental quantities which characterize the interface between two materials. Although these quantities are identical for interfaces involvin…
Liquid droplets on a free-standing glassy membrane: deformation through the glass transition
Adam Fortais, Rafael D. Schulman, Kari Dalnoki-Veress
In this study, micro-droplets are placed on thin, glassy, free-standing films where the Laplace pressure of the droplet deforms the free-standing film, creating a bulge. The film's…
Elastocapillary bending of microfibers around liquid droplets
Rafael D. Schulman, Amir Porat, Kathleen Charlesworth +4
We report on the elastocapillary deformation of flexible microfibers in contact with liquid droplets. A fiber is observed to bend more as the size of the contacting droplet is incr…
