Droplet impact is a ubiquitous phenomenon in nature, daily life, and industrial processes. It
is thus crucial to tune the impact outcomes for various applications. As a special outcome of …

Mixing is the operation by which a system evolves under stirring from one state of simplicity—
the initial segregation of the constituents—to another state of simplicity—their complete …

We review studies of levitating droplets over liquid–gas interfaces and dry solid surfaces
with a focus on the physical mechanisms of levitation under different conditions. A …

Droplet impact onto liquid pools is a canonical scenario relevant to numerous natural
phenomena and industrial processes. However, despite their ubiquity, multi-fluid systems …

Metal additive manufacturing technologies keep receiving a great deal of interest as well as
strong requests to develop methods to link the process science to printed parts performance …

When a liquid drop falls on a solid substrate, the air layer between them delays the
occurrence of liquid–solid contact. For impacts on smooth substrates, the air film can even …

The impact of a droplet on a deep pool of water with a flat-free surface results in a deep
cavity followed by the emergence of a thick jet with a secondary drop when the Froude …

Air cushioning widely occurs when a droplet impacts onto a solid or fluid surface at low
velocity, which is mediated by the lubrication pressure of a thin air layer. Such air cushioning …

The coalescence dynamics of ethanol drops injected from a needle on the free-surface of an
ethanol pool maintained at a higher temperature than the drop is experimentally studied …

Droplet coalescence is an important process in nature and various technologies (eg, inkjet
printing). Here, we unveil the surfactant mass transport mechanism and report on several …
