Fast, active droplet interaction: coalescence and reactive mixing controlled by electrowetting on a superhydrophobic surface.
نویسندگان
چکیده
A novel electrowetting-on-dielectrics (EWOD) device in open planar geometry allows probing of droplet mixing on a superhydrophobic substrate under quasi contact-free conditions. We demonstrate a droplet-based microreactor with integrated convective-flow mixing for the reactive-mixing of CaCl(2)/Na(2)CO(3) solutions. The device provides unique conditions for scattering, spectroscopy and imaging probes requiring an unobstructed droplet-access.

متن کاملRebounding droplet-droplet collisions on superhydrophobic surfaces: from the phenomenon to droplet logic.
When water droplets impact each other while traveling on a superhydrophobic surface, we demonstrate that they are able to rebound like billiard balls. We present elementary Boolean logic operations and a flip-flop memory based on these rebounding water droplet collisions. Furthermore, bouncing or coalescence can be easily controlled by process parameters. Thus by the controlled coalescence of r...

We introduce a droplet-jumping phenomenon on a superhydrophobic surface driven by the resonant AC electrowetting. The resonant electrical actuation enables a droplet to accumulate sufficient surface energy for jumping, and superhydrophobic surface minimizes adhesion and hysteresis effects. They provide the effective energy conversion from the surface energy to the kinetic energy and improve the...
متن کاملProbing droplets on superhydrophobic surfaces by synchrotron radiation scattering techniques
Droplets on artificially structured superhydrophobic surfaces represent quasi contact-free sample environments which can be probed by X-ray microbeams and nanobeams in the absence of obstructing walls. This review will discuss basic surface wettability concepts and introduce the technology of structuring surfaces. Quasi contact-free droplets are compared with contact-free droplets; processes re...
متن کاملFluorinated Superhydrophobic Surfaces for Digital Microfluidic Devices with Electrowetting on Dielectric and Magnetic Actuation
Digital microfluidics (DMF) is a popular alternative to traditional in-channel microfluidics, which allows precise control of individual droplets. Most commonly used droplet manipulation methods for DMF are electrowetting on dielectric (EWOD) and magnetic actuation. Both methods require high surface hydrophobicity to facilitate droplet movement, and often superhydrophobic surfaces are used to f...
