Cross-stream migration of droplets in a confined shear-thinning viscoelastic flow: Role of shear-thinning induced lift
TL;DR: In this article, the role of a shear-thinning induced lift force (FSM) in cross-stream migration of droplets in a confined STVE flow was investigated.
Journal ArticleDOI
Autonomous transport and splitting of a droplet on an open surface
Imdad Uddin Chowdhury,Pallab Sinha Mahapatra,Ashis Kumar Sen,Arvind Pattamatta,Manish K. Tiwari +4 more
TL;DR: In this paper, the authors demonstrate a power-free technique for transport and splitting of droplets on open surfaces using continuous wettability gradients, where a droplet moves continuously from a low to a high wetability region on the Wettability-gradient surface.
Journal ArticleDOI
Electrospray performance of interacting multi-capillary emitters in a linear array
Journal ArticleDOI
Continuous electrical lysis of cancer cells in a microfluidic device with passivated interdigitated electrodes.
TL;DR: A simple, chemical-free, and automated technique based on a microfluidic device with passivated interdigitated electrodes with DC fields for continuous EL of cancer cells is reported, showing that the critical problems in EL, bubble formation and electrode erosion, can be circumvented by passivating the electrodes with a thin layer of polydimethylsiloxane.
Journal ArticleDOI
Combined acoustic relocation and acoustophoretic migration for particle transfer between co-flowing fluids in a microchannel
A. Nath,L. Malik,Ashis Kumar Sen +2 more
TL;DR: In this article, the authors show how fluid relocation in combination with primary radiation force can be used to effect medium exchange and separation of different-sized particles suspended in the fluid by controlling the flow rates and acoustic energy density.
