Inkjet printing is the most widespread technological application of microfluidics. It is
characterized by its high drop productivity, small volumes, and extreme reproducibility. This …

A common feature of many free surface flows—drop/bubble breakup or coalescence and
film/sheet rupture—is the occurrence of hydrodynamic singularities. Accurately computing …

Inkjet printing, initially invented for text and pattern printing, has been extensively used to
fabricate electronic, mechanical, and even biological devices. Numerous reviews focused …

Jet formation and break-up in inkjet printing has been studied and understood mainly for
pure liquids. Questions remain as to the role of surfactants on the inkjet printing process at …

This study aims to elucidate, for the first time, the intricate fundamental physics governing the
dispersion dynamics of a surfactant-laden two-phase liquid–liquid system in the well-known …

We study the effect of surfactants on the dynamics of a drop-interface coalescence using full
three-dimensional direct numerical simulations. We employ a hybrid interface-tracking/level …

Long and slender liquid filaments are produced during inkjet printing, which can
subsequently either retract to form a single droplet, or break up to form a primary droplet and …

We study the bursting of a bubble covered with a surfactant experimentally. We conclude
that the bubble bursting takes longer than that of a surfactant-free bubble with the same …

We present a numerical study of the main substages preceding aerosol formation via
bursting bubbles: capillary wave propagation along the bubble, convergence at the bubble's …

This article describes a series of modern developments carried out by the inkjet community
in its quest to improve material compatibility, printing quality, and reliability. Recent progress …
