The present study is focused on micromixing enhancement techniques for electroosmotic flows in a modulated microchannel with modified topology by utilizing heated blocks the surface of microchannel. carry higher temperatures as compared to other portions channel wall, resulting sharp variation temperature fluid. species transport governed Nernst–Planck equation form adding thermo-electrochemica...

The dominance of surface tension and viscous effects over body forces such as inertia, gravity or centrifugal force makes fluid actuation and particle manipulation at microscale dimensions extremely difficult. We demonstrate the possibility of exploiting electric fields to drive unstable turbulent-like flows for micromixing and complex flows for efficient particle separation and concentration. ...

Micromixing devices often utilize complex architectures to mix miscible liquid streams and can be expensive fabricate. Here, we developed, built, experimentally tested, computationally analyzed a serpentine micromixer that fabricated using simple tools supplies available in non-microdevice dedicated laboratories. Fluorescence imaging was used quantify its mixing effectiveness experimentally. A ...

The yields of chemical reactions are highly dependent on the mixing pattern between reactants. Herein, we report modification a meso-micromixing interaction reaction model which is applied in batch reactors by leveraging flow characteristics continuous reactors. Both experimental and model-predicted were compared using classical Villermaux–Dushman method self-designed split recombination reacto...

The authors present a novel ultra scale-down (USD) methodology for the characterization of flocculation processes. This USD method, consisting of a multiwell, magnetically agitated system that can be fitted on the deck of a liquid handling robot, mimicked the flocculation performance of a nongeometrically similar pilot-scale vessel representing greater than three orders of magnitude scale-up. M...

We acoustically modulated the localized surface plasmon resonances (LSPRs) of metal nanostructures integrated within microfluidic systems. An acoustically driven micromixing device based on bubble microstreaming quickly and homogeneously mixes multiple laminar flows of different refractive indices. The altered refractive index of the mixed fluids enables rapid modulation of the LSPRs of gold na...
