Droplet group production in an AC electro- flow focusing microdevice
(Springer, 2017-09)
We report the production of droplet groups with a controlled number of drops in a microfluidic electro-flow focusing device under the action of an AC electric field. This regime appears for moderate voltages (500-700 V ...

Controllable production of Janus ligaments by AC fields in a flow‑focusing junction
(Springer, 2019-01)
We report the production of bicomponent Janus filaments of miscible aqueous fluids in a microfluidic electro-flow-focusing device under the action of an AC electric field. The production of liquid filaments can lead to ...

Combining DC and AC electric fields with deterministic lateral displacement for micro- And nano-particle separation
(American Institute of Physics, 2019)
This paper describes the behavior of particles in a deterministic lateral displacement (DLD) separation device with DC and AC electric fields applied orthogonal to the fluid flow. As proof of principle, we demonstrate ...

Microwave-induced water flow in a microchannel built on a coplanar waveguide
(AIP Publishing, 2011)
We present experimental and numerical investigations of water flow in a microsystem induced by microwave electric fields. Microwave dielectric heating induces gradients of temperature which produce spatial variations in ...

Breakup length of AC electrified jets in a microfluidic flow‑focusing junction
(Springer, 2015-06)
Electroactuation of liquid-liquid interfaces offers promising methods to actively modulate droplet formation in droplet-based microfluidic systems. Here, flow-focusing junctions are coupled to electrodes to control droplet ...

Numerical study of dc-biased ac-electrokinetic flow over symmetrical electrodes
(AIP Publishing, 2012)
This paper presents a numerical study of DC-biased AC-electrokinetic (DC-biased ACEK) flow over a pair of symmetrical electrodes. The flow mechanism is based on a transverse conductivity gradient created through incipient ...

AC electrified jets in a flow-focusing device: Jet length scaling
(AIP Publishing, 2016)
We use a microfluidic flow-focusing device with integrated electrodes for controlling the production of water-in-oil drops. In a previous work, we reported that very long jets can be formed upon application of AC fields. ...

Electrorotation of semiconducting microspheres
(American Physical Society, 2019)
We study experimentally the electrorotation (ROT) of semiconducting microspheres. ZnO microspheres obtained by a hydrothermal synthesis method are dispersed in KCl aqueous solutions and subjected to rotating electric fields. ...

AC electrokinetic biased deterministic lateral displacement for tunable particle separation
(Royal Society of Chemistry, 2019)
We describe a novel particle separation technique that combines deterministic lateral displacement (DLD) with orthogonal electrokinetic forces. DLD is a microfluidic technique for continuous flow particle separation based ...
