A bouncing oil droplet in a stratified liquid and its sudden death

Yanshen Li, Christian Diddens, Andrea Prosperetti +3

Droplets can self-propel when immersed in another liquid in which a concentration gradient is present. Here we report the experimental and numerical study of a self-propelling oil…

The effect of the liquid layer thickness on the dissolution of immersed surface droplets

Qingguang Xie, Jens Harting

Droplets on a liquid-immersed solid surface are key elements in many applications, such as high-throughput chemical analysis and droplet-templated porous materials. Such surface dr…

Optimal cell transport in straight channels and networks

Alexander Farutin, Zaiyi Shen, Gael Prado +9

Flux of rigid or soft particles (such as drops, vesicles, red blood cells, etc.) in a channel is a complex function of particle concentration, which depends on the details of induc…

Expansion Dynamics After Laser-Induced Cavitation in Liquid Tin Microdroplets

Dmitry Kurilovich, Tiago de Faria Pinto, Francesco Torretti +9

The cavitation-driven expansion dynamics of liquid tin microdroplets is investigated, set in motion by the ablative impact of a 15-ps laser pulse. We combine high-resolution strobo…
