Abstract In our previous work, a new flow route was developed—a so‐called perpendicular shear force–induced droplet formation—in self‐designed simple T‐junction microchannel device. this the crossflowing rupture technique used to prepare monodisperse droplets in similar device and successfully prepared ranging from 50 500 μm with polydispersity index (σ) values of <2%. Two kinds patterns plug drop microchannels could be formed. By changes surfactant concentration, interfacial tension...
Abstract Electrowetting‐on‐dielectric (EWOD), recognized as the most successful electrical droplet actuation method, is essential in diverse applications, ranging from thermal management to microfluidics and water harvesting. Despite significant advances, it remains challenging achieve repeatability, high speed, simple circuitry EWOD‐based manipulation on superhydrophobic surfaces. Moreover, its efficient operation typically requires electrode arrays sophisticated circuit control. Here, a...
This letter presents a simple way to prepare monodisperse O/W and W/O emulsions in the same T-junction microfluidic device just by changing wetting properties of microchannel wall with different surfactants. Highly uniform droplets ranging from 50 400 μm polydispersity index (σ) value less than 2% were successfully prepared. With change surfactants surfactant concentrations, interfacial tension varied, disordered or ordered two-phase flow patterns could be controllable. Monodisperse prepared...
Abstract This work focuses on the dispersion of micromonodispersed droplets and bubbles in capillary embedded T‐junction microfluidic devices. The effects microchannel structure, operating conditions, physical properties rules were carefully investigated. It was found that extended could greatly affect rules, which favorable for reducing dispersed size. size mainly dominated by Ca number, phase flow rate viscosity ratio two phases also very important. mechanism devices discussed seriously...
Abstract Contactless, spatiotemporal droplet maneuvering plays a critical role in wide array of applications, including drug delivery, microfluidics, and water harvesting. Despite considerable advancements, challenges persist the precise transportation, splitting, controlled steering, functional adaptability droplets when manipulated by electrical means. Here, we propose use orbital electrowetting (OEW) on slippery surfaces to enable versatile under variety conditions. The asymmetric force...
The phenomenon of droplet impact is commonly found in industrial and agricultural processes. basic characteristics theories a impacting solid walls have been extensively studied, but the regulation has not adequately examined. This study investigates on hydrophobic surface based alternating current electrowetting-on-dielectric (AC EWOD). When water impacts virgin Teflon at 1.06 m/s, partial rebound occurs. an AC voltage applied to electrode pair underneath layer, stabilized after impact. To...
Abstract This work describes a novel method for the preparation of monodispersed calcium alginate microbeads in microfluidic device. A device comprising two cross‐junction channels and synthesizing channel was designed by controlling mixing condition with laminar flow two‐phase droplet devices. At first junction, side streams, sodium aqueous solution chloride solution, were separated to prevent contact injection deionized water middle channel. Then mixture induced into droplets focusing...
Centrifugal microfluidics or lab-on-a-disc (LOAD) is a promising branch of lab-on-a-chip microfluidics. Besides effective fluid transportation and inherently available density-based sample separation in centrifugal microfluidics, uniform actuation flow on the disc makes platform compact scalable. However, natural radially outward force LOAD system limits its capacity to perform complex manipulation steps. In order increase freedom integration system, we propose binary platform. With help...
Abstract The phenomenon of droplet impact is widely observed in nature and industrial processes. No matter the intrinsic wettability (hydrophobic, hydrophilic, superhydrophobic) surface, postimpact droplets tend to rebound or splash. dynamics have been well investigated but inhibition rebounding splashing requires further exploration. This paper proposes a periodic wetting surface (PWS) driven by triboelectric nanogenerator (TENG) for efficient collection. With high‐voltage electric signal...

Possible business models for HESs industry transportation then presented, cost benefit functions stakeholders HES were created, model with multi-party participation modeled multi-objective...
Capillary-wave propellers (CWPs) based on the phenomenon of electrowetting-on-dielectric (EWOD) have shown great potential for floating-object propulsion, heat-transfer enhancement, and fluid thermophysical property measurement. However, small amplitude EWOD-induced capillary-wave limits performance CWP in practical applications. Herein, a with concave curvature is proposed to enlarge amplitude. The formation propagation capillary wave are visualized by using high-speed camera free-surface...
Capillarity describes liquid flowing against gravity in an open narrow tube with certain wettability and is well described by the Young–Laplace equation. However, modeling of gas compression a confined due to capillary action variable yet be established. Thus, this study observes models relation between pressure increment water contact angle (CA) variation induced electrowetting-on-dielectric (EWOD).
