Electrospray is a relatively mature research field, with sustained and growing activity. It has
attracted researchers from diverse application fields. Electrospray is perhaps best known as …

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 …

Extrusion bioprinting has been widely used to extrude continuous filaments of bioink (or the
mixture of biomaterial and living cells), layer-by-layer, to build three-dimensional constructs …

Jets, ie collimated streams of matter, occur from the microscale up to the large-scale
structure of the universe. Our focus will be mostly on surface tension effects, which result …

Double emulsions are highly structured fluids consisting of emulsion drops that contain
smaller droplets inside. Although double emulsions are potentially of commercial value …

Deciphering the multifactorial determinants of tumor progression requires standardized high-
throughput preparation of 3D in vitro cellular assays. We present a simple microfluidic …

A liquid forced through an orifice into an immiscible fluid ultimately breaks into drops due to
surface tension. Drop formation can occur right at the orifice in a dripping process …

Dripping, jetting and tip streaming have been studied up to a certain point separately by both
fluid mechanics and microfluidics communities, the former focusing on fundamental aspects …

Microfluidic chips provide unparalleled control over droplets and jets, which have advanced
all natural sciences. However, microfluidic applications could be vastly expanded by …

Levitation and controlled motion of matter in air have a wealth of potential applications
ranging from materials processing to biochemistry and pharmaceuticals. We present a …
