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 …

Inspired by Namib Desert beetle and leaf venation, a wettability-integrated system consisting
of wettability-hybrid coatings and venation-like patterns was designed and successfully …

Coalescing drops spontaneously jump out of plane on a variety of biological and synthetic
superhydrophobic surfaces, with potential applications ranging from self-cleaning materials …

This work examines the fog-harvesting ability of patterned and non-patterned samples in
spray chamber experiments. The samples were prepared from different materials and the …

My interest in dew and Breath Figures (BFs, the pattern that forms on a cold surface when
breathing) started long ago when I was intrigued to see a ring around a streetlight from the …

The coalescence of viscous drops on a substrate is studied experimentally and theoretically.
We consider cases where the drops can have different contact angles, leading to a very …

The coalescence of water drops on a substrate is studied experimentally. We focus on the
rapid growth of the bridge connecting the two drops, which very quickly after contact ensues …

Coalescence of two droplets on a solid substrate is an interfacial phenomenon that imposes
the challenges of capturing the complex contact line motion and energy interaction between …

Coalescence and breakup of drops are classic problems in fluid physics that often involve
self-similarity and singularity formation. While the coalescence of suspended drops is …
