Merging of isolated liquid drops is a common phenomenon that may greatly be influenced by adding polymeric contents to the liquid. Here, we bring out an exclusive control on dynamics intermediate bridge, thus, formed via exploiting interactions exciting electric field with trace amount inclusions present in intermingling drops. Our results unveil unique competition elastic recovery and time-oscillatory forcing during drop-unification at early times. However, damped oscillations as specific...
The response time for maximum drop deformation and its comparison with different scales is established verified experiments. applied fluctuation achieved by applying a single wave perturbation of electrowetting desired amplitude frequency. To pinpoint the importance initial actuation conditions, variance in studied. focus this study was to analyze wide range mechanism varied or surrounding medium viscosities. cyclic compared equivalent mass–spring–dampener system, limitations approach are...
Manipulating the coalescence of microdroplets has recently gained enormous attention in digital microfluidics and biological chemical industries. Here, between two sessile droplets is induced by spreading them due to electrowetting. The electrocoalescence dynamics investigated for a wide range operating parameters such as electrowetting number, Ohnesorge driving frequency, drop surrounding medium viscosity ratio. characteristic time scale from classical lubrication theory modified with an...
We report an electrode-embedded on-chip platform technology for the precise determination of ultra-short (of order a few nanoseconds) relaxation times dilute polymer solutions, by deploying time-alternating electrical voltages.
This work analyzes the transient wetting dynamics of droplets in viscous media with appropriate governing parameters and examines drop's response immediately after actuation, retraction resultant dynamics, effect multiple wave actuation on droplet transition.
The characteristic time for the electrocoalescence of two sessile drops is identified and verified wide range operating parameters such as Ohnesorge, Electrowetting number, driving frequency drop to surrounding medium viscosity. Elegant mechanism devised circumvent repulsion promote coalescence at merging three phase contact lines electrospreading drops. With revised definition scale, we demonstrated universality bridge growth early times more than twenty different scenarios in triplicates....
