Emergence of Bimodal Motility in Active Droplets
To explore and react to their environment, living micro-swimmers have developed sophisticated strategies for locomotion - in particular, motility with multiple gaits. To understand the physical
Ultra-low-cost ‘paper-and-pencil’ device for electrically controlled micromixing of analytes
We demonstrate here a frugal, printing-based fabrication methodology for paper channels, in an effort towards developing an inexpensive micromixing device. The proposed fabrication methodology
Electrokinetics with "paper-and-pencil" devices.
TLDR
The underlying electrokinetic phenomenon results in enhanced liquid transport through the paper-fibre matrix, which exhibits significant active electrical controllability and improved repeatability.
Electrohydrodynamics within the electrical double layer in the presence of finite temperature gradients.
TLDR
This model takes into consideration all the pertinent phenomenological aspects stemming from the imposed thermal gradients by a full-fledged coupling among the electric potential, the ionic species distribution, the fluid velocity and the local fluid temperature fields, without resorting to ad hoc simplifications.
Breath Figures under Electrowetting: Electrically Controlled Evolution of Drop Condensation Patterns.
TLDR
It is shown that electrowetting with structured electrodes significantly modifies the distribution of drops condensing onto flat hydrophobic surfaces by aligning the drops and by enhancing coalescence, and that the resulting reduced surface coverage under EW enhances the net heat transfer.
Analytical Solution for Thermally Fully Developed Combined Electroosmotic and Pressure-Driven Flows in Narrow Confinements With Thick Electrical Double Layers
In the present paper, closed form solutions for the Nusselt number are obtained for hydrodynamically and thermally fully developed combined electroosmotic and pressure-driven flows in narrow
Controlling shedding characteristics of condensate drops using electrowetting
We show here that ac electrowetting (ac-EW) with structured electrodes can be used to control the gravity-driven shedding of drops condensing onto flat hydrophobic surfaces. Under ac-EW with straight
