Abstract Surface-enhanced Raman spectroscopy (SERS) microfluidic system, which enables rapid detection of chemical and biological analytes, offers an effective platform to monitor various food contaminants disease diagnoses. The efficacy SERS systems is greatly dependent on the sensitivity reusability substrates ensure repeated use for prolonged periods. This study proposed a novel process femtosecond laser nanoparticle array (NPA) implantation achieve homogeneous forward transfer gold NPA...
Utilizing the residual droplet produced from liquid bridge breakup for microdroplet deposition serves as an important supplementary method to conventional printing techniques. However, this approach typically relies on mechanical motion form and break between donor acceptor surfaces, resulting in a relatively complex process low efficiency (typically limited several Hertz). Here, we propose novel contact based meniscus vibration (MVCP). A tubular piezoelectric dispenser is employed donor,...
Inkjet printing (IJP) is an old but still vivifying technique for flexible and cost-effective of various kinds functional inks. Normally, IJP can only work in gaseous environments. Here, it shown that traditional piezoelectric be performed liquid environments with a totally different droplet dispensing manipulating mechanism. With the same nozzle, volume droplets printed carrier thousands times smaller than those air. Therefore, this demonstrates working mode highly improved resolution...
Abstract In this letter, we report functions of surface roughening and fluorination on suppressing linear metal particle-induced spacer charge accumulation. An appropriate increase in conductivity by short-term not only increases the particle lifting voltage, but also weakens activation. The shows reduced density roughened spacer, while modification significantly suppresses surface. For fluorinated samples, decrease intrinsic lower electric field (due to an conductivity) near triple junction...
Abstract Despite their specific methodologies, all current noncontact printing techniques such as inkjet (IJP), involve the break‐up of a liquid meniscus during separation ink droplet from bulk reservoir. Often, results in formation one or more satellite whose volumes are several orders magnitude smaller than primary droplet. Many attempts directed to suppress control droplets because they blur result. For first time, simple mechanism by which single is exclusively formed and substrate gas...
The most common dielectric in sinking electrical discharge machining (EDM) is kerosene. However, kerosene inflammable; besides, it can be decomposed and release harmful gases during process. And, owing to its low viscosity, using EDM has efficiency. Accordingly, conventional as poor safety, unfriendly environment impact, A new water-in-oil (W/O) nanoemulsion presented this paper. This W/O not only eliminate the hazards from operator but also improve performance of EDM. research aims...
Inkjet printing, originally invented for text and pattern is now central to many industrial applications, such as printed electronics, flexible 3-D printing of mechanical even biological devices. However, constrained by the droplets’ ejection mechanism, accuracy traditional inkjet limited size its orifice, it difficult achieve a volume droplets at femtolitre scale, which hinders further application in above fields. To this end, we propose confined interface vibration (CIVIJP) technique,...
In this paper, we investigate the exit dynamics of a sphere launched underneath liquid bath surface at prescribed impact velocity. Spheres with radii approximate or smaller than capillary length are considered. The process can be sequenced into partial stage that forms coated layer, and full an attached ligament. A bouncing-off regime, lower pinch-off penetration upper regime identified, separating by Weber number switching number. phase diagram is revealed, where two critical numbers functions Bond
Confined interface vibration inkjet printing (CIVIJP) in another immiscible liquid phase has been investigated previously as a novel strategy proposed for actively generating ultra-fine droplets, which can be dozens of times smaller than the orifice from they are ejected. However, working frequency this CIVIJP technique is much lower traditional printing, and unique droplet generation mechanism behavior still unapprehended at high frequency. Here, was explored to reveal improve its...
The precise and effective generation of micron-sized droplets is one the most common important issues for droplet-based microfluidics. Active droplet makes use additional energy input in promoting interfacial instabilities generation. Here, we report a new technique active femtoliter microfluidic systems using confined vibration (CIV). CIV formed at orifice traditional inkjet nozzle first by pushing liquid out then pulling it back. Droplets are pinched off during withdrawal process, this...
Efficient and facile generation of tiny droplets is critical to many cutting-edge applications, such as flexible electronic skin, customized circuits, micro-electro-mechanical systems. However, conventional piezoelectric inkjet printing techniques show more prominent problems high driving voltage relatively low frequency. Here, a novel principle for high-throughput droplet dispensing was proposed based on the resonance liquid column within glass capillary. The mechanisms this technique were...
