The dynamics of a liquid droplet impacting a liquid film of different compositions is critical for
many industrial processes, including additive manufacturing and bio-printing. In this work we …

Recent studies have revealed the air-cushioning effect of droplet impact upon various
surfaces and although pure water droplets have extensively been studied, the air …

We experimentally investigate microliter-sized water droplet impact on solid and hollow
square micropillared polydimethylsiloxane substrates. Micropillared substrates with different …

The dynamics of two vertically coalescing drops and a pool of the same liquid have been
investigated using a Coupled Level Set and Volume of Fluid (CLSVOF) method. Such a …

Whispering gallery mode resonators provide an intriguing platform for precision
measurement due to their high responsivity and low detection limit. Here, we propose and …

Controlling the impact process of a droplet impacting a liquid film has remained a wide-open
challenge. The existing passive techniques lack precise on-demand control of the impact …

Droplet impact on surfaces is ubiquitous in many natural and industrial processes. While the
impact dynamics of droplets composed of simple fluids have been studied extensively …

Volatile drop impacts are commonplace among various industrial and natural processes and
are most often studied under Leidenfrost conditions, where a vaporized film sustains the …
