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

The merging of two fluid drops is one of the fundamental topological transitions occurring in
free surface flow. Its description has many applications, for example, in the chemical industry …

Surface engineering at the nanoscale is a rapidly develo** field that promises to impact a
range of applications including energy production, water desalination, self-cleaning and anti …

The operation of a piezo inkjet printhead involves a chain of processes in many physical
domains at different length scales. The final goal is the formation of droplets of all kinds of …

This review presents recent technological advances in charge-coupled-device ultrahigh-
speed video cameras and their applications in experimental fluid mechanics. Following a …

We study droplet coalescence in a molecular system with a variable viscosity and a colloid-
polymer mixture with an ultralow surface tension. When either the viscosity is large or the …

When two liquid drops touch, a microscopic connecting liquid bridge forms and rapidly
grows as the two drops merge into one. Whereas coalescence has been thoroughly studied …

The nucleolus is a membraneless organelle embedded in chromatin solution inside the cell
nucleus. By analyzing surface dynamics and fusion kinetics of human nucleoli in vivo, we …

Droplet dynamics and condensation phenomena are widespread in nature and industrial
applications, and the fundamentals of various technological applications. Currently, with the …

The coalescence phenomenon of drops in liquid/liquid systems is reviewed with particular
focus on its technical relevance and application. Due to the complexity of coalescence, a …
