Precise and effective control of droplet generation is critical for applications of droplet
microfluidics ranging from materials synthesis to lab-on-a-chip systems. Methods for droplet …

Microreaction technology is preferential in process intensification and chemical synthesis,
especially in multiphase applications. A thorough understanding of the hydrodynamics and …

Surfactants are employed in microfluidic systems not just for drop stabilisation, but also to
study local phenomena in industrial processes. On the scale of a single drop, these include …

Surfactant mass transport towards an interface plays a critical role during formation of
emulsions, foams and in industrial processes where two immiscible phases coexist. The …

This paper starts with short descriptions of emulsion preparation methods used at large and
smaller scales. We give scaling relations as they are generally used, and focus on the …

Drop formation in a microfluidic flow-focusing device (cross-junction) was studied in
absence and presence of one of two ionic surfactants. Four different flow regimes …

Dynamic interfacial tension was studied experimentally during drop formation in a flow-
focusing microchannel. A low viscosity silicone oil (4.6 mPa s) was the continuous phase …

The role of surfactants in the flow of a droplet driven by a pressure gradient through a
constricted microchannel is simulated by using our recently developed lattice Boltzmann …

The formation of droplets in an immiscible liquid in the presence of different surfactants was
studied experimentally using a flow-focusing microchannel. A low viscosity silicone oil (4.6 …

Liquid–liquid dispersion coupled with droplet formation and mass transfer of surfactants is
one of the most typical phenomena in many chemical processes. As in every aspect of this …
