Wetting and evaporation of sessile droplets are ubiquitous in nature and of importance to
many industrial and everyday processes. While most of the research on sessile droplets has …

When a volatile droplet is deposited on a floating swellable sheet, it becomes asymmetric,
lobed and mobile. We describe and quantify this phenomena that involves nonequilibrium …

Despite surface energies dictating complete wetting, it has been classically observed that
volatile alkanes do not spread completely on glass substrates, and faster evaporation rates …

Hypothesis In droplet microfluidics applications, flow control and mixing in a small volume
without any active external devices is a challenge. Vapor-mediated solutal Marangoni flows …

Droplet motion on surfaces influences phenomena as diverse as microfluidic liquid
handling, printing technology, and energy harvesting. Typically, droplets are set in motion by …

Contactless droplet transport has gained intensive attention in recent years. In this study, the
motion of a sessile binary droplet or a pure water droplet under the contactless Marangoni …

Multidroplet evaporation is a common phase-change phenomenon not only in nature but
also in many industrial applications, including inkjet printing and spray cooling. The …

In contrast to microdroplet condensation with high contact angles, the one with low contact
angles remains unclear. In this study, we investigated dynamics of microdroplet …

Actuation of sub-millimeter sized droplets has important implications in heat transfer,
microfluidics, and self-cleaning surfaces. Here, we report the motion of satellite droplets …

Digital microfluidics based on sessile droplets has emerged as a promising technology for
various applications including biochemical assays, clinical diagnostics, and drug screening …
