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

Inkjet printers eject drops from microscopic nozzles and deposit them on substrates. For a
number of years after its initial development, inkjet printing remained a method for …

Exosomes, molecular cargos secreted by almost all mammalian cells, are considered as
promising biomarkers to identify many diseases including cancers. However, the small size …

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 …

Electrospinning is an efficient and flexible method for nanofiber production, but it is
influenced by many systemic, process, and environmental parameters that govern the …

Two phase systems are ubiquitous in processes and products, and in both cases
performance is maximized when precise control over the individual phases, and the …

Break-up of viscoelastic filaments is pervasive in both nature and technology. If a filament is
formed by placing a drop of saliva between a thumb and forefinger and is stretched, the …

Particle focusing in planar geometries is essentially required in order to develop cost-
effective lab-on-a-chips, such as cell counting and point-of-care (POC) devices. In this study …

The non-Newtonian flow of dilute aqueous polyethylene oxide (PEO) solutions through
micro-fabricated planar abrupt contraction–expansions is investigated. The small …

We show that visualization and analysis of capillary-driven thinning and pinch-off dynamics
of the columnar neck in an asymmetric liquid bridge created by drip**-onto-substrate can …
