Modeling complex motility patterns for autophoretic microswimmers
Anupriya Dutta Roy, Smita S. Sontakke, Arvind Kumar +2
Symmetry breaking is essential for biological microswimmers to achieve locomotion in viscous environments. Such asymmetry in the swimming mechanism enables the generation of direct…
Rupture of a surfactant-laden draining thin film
Atul S Vivek, Ranabir Dey, Harish N Dixit
Surfactant-laden thin liquid films overlaid on solid substrates are encountered in a variety of industrial and biological settings. As these films reach submicron thickness, they t…
Electrowetting-Controlled Dropwise Condensation with Patterned Electrodes: Physical Principles, Modeling, and Application Perspectives for Fog Harvesting and Enhanced Heat Transfer
Harmen Hoek, Ranabir Dey, Frieder Mugele
Patterning the wettability of solid surfaces is a successful strategy to control the dropwise condensation of vapor onto partially wetting solid surfaces. We followed the condensat…
Controlling shedding characteristics of condensate drops using electrowetting
Ranabir Dey, Jander Gilbers, Davood Baratian +3
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…
Contact angle hysteresis and oil film lubrication in electrowetting with two immiscible liquids
Jun Gao, Niels Mendel, Ranabir Dey +2
Electrowetting (EW) of water drops in ambient oil has found a wide range of applications including lab-on-a-chip devices, display screens, and variable focus lenses. The efficacy o…
Breath figures under electrowetting: electrically controlled evolution of drop condensation patterns
Davood Baratian, Ranabir Dey, Harmen Hoek +2
We show that electrowetting (EW) with structured electrodes significantly modifies the distribution of drops condensing onto flat hydrophobic surfaces by aligning the drops and by…
Electrically modulated dynamic spreading of drops on soft surfaces
Ranabir Dey, Ashish Daga, Sunando DasGupta +1
The intricate interaction between the deformability of a substrate and the dynamic spreading of a liquid drop on the same, under the application of an electrical voltage, has remai…
Electrically Modulated Wetting of Drops on Soft Dielectric Films
Ranabir Dey, Sunando DasGupta, Suman Chakraborty
The inter-connection between the elasticity of a dielectric film and the wetting of a sessile drop on the same, under an applied electrical voltage, remains unaddressed. Here, we r…
Electrohydrodynamics within electrical double layer in a pressure-driven flow in presence of finite temperature gradients
Tanmay Ghonge, Jeevanjyoti Chakraborty, Ranabir Dey +1
A wide spectrum of electrokinetic studies is modelled as isothermal ones to expedite analysis even when such conditions may be extremely difficult to realize in practice. As a clea…
