Abstract Magnetic manipulation of droplets has emerged as a promising strategy to achieve several complex tasks ranging from targeted drug delivery and micro‐robotics controlled chemical synthesis. Hence, proper control in creating magnetically responsive is indispensable for successful implementation. Here, an impact‐based encapsulation technique employed create stable ferrofluid‐wrapped single‐liquid compound inside water bath. Thereafter, permanent magnet used manipulate the resulting...

Impact-induced transformation of bacteria from a viable to dormant mode.

Encapsulation protects vulnerable cores in an aggressive environment and imparts desirable functionalities to the overall encapsulated cargo, including control of mechanical properties, release kinetics, targeted delivery. Liquid–liquid encapsulation create such capsules, where a liquid layer (shell) is used wrap another (core), attractive value proposition for ultrafast (∼100 ms). Here, we demonstrate robust framework stable liquid–liquid encapsulation. Wrapping achieved by simple...

The radiolytic stability of DHOA, a high molecular weight N,N‐dialkyl amide has been investigated to evaluate its performance under PUREX process conditions vis–a–vis TBP. Gas chromatographic studies revealed the presence caprylic acid, dihexylamine and dihexylketone in irradiated DHOA. Batch distribution Pu, U, fission products (144Ce, 103,106Ru, 137Cs) were carried out using samples 1.1 M DHOA TBP n‐dodecane, which showed significant retention as compared that even after successive...

Abstract Encapsulated magnetic microdroplets are of paramount importance in drug targeting and therapeutic applications. However, conventional techniques for generating encapsulated suffer from several challenges, including lack monodispersity, inflexibility core–shell combinations, complex device architecture to achieve encapsulation. Herein, a facile magnet‐assisted framework controllably wrap ferrofluid (FF) droplets inside polydimethylsiloxane (PDMS) floating on water bath is developed....

Abstract Conventional microscopy‐driven sperm health monitoring systems suffer from high infrastructural costs and complex protocols. Here, a simple, economical motility assessment system is proposed. Based on cantilever‐deflection‐based direct force measurement capable of detecting wetting forces in the range ≈µN, it found that adhesion live motile cell‐laden droplets dependent suspension. Further, observed inside droplet decreases with time, concerned master substrate demonstrates an...

This study explores the encapsulation of magnetic and non-magnetic hydrogels within a liquid medium using liquid-liquid technique. The process involves suspension in laser oil,...

In this study, we examine the process of filament thinning that occurs when a liquid droplet impacts thin polymeric interfacial layer floating in water pool. We used partially cured polydimethylsiloxane solutions and polybutene gel mixed with varying volumes for our experiments. The dynamics showed drags into pool, creating an air cavity, followed by its closer. Thereafter, filament-thinning phase occurs. Initially, was rapid due to crater interface retraction caused impact. After receded,...

Abstract The leather industry, which utilizes by‐products of the meat industry as raw materials, produces substantial waste, with chrome shavings being a major by‐product. These are primarily composed collagenous Cr (III) complexes and rich in protein. In this study, collagen hydrolysate (CH) was extracted from through enzymatic hydrolysis, its chemical properties were analyzed. CH combined chitosan (C) to develop microcapsules containing clove oil, known for antifungal antimicrobial...

In contrast to microdroplet condensation with high contact angles, the one low angles remains unclear. this study, we investigated dynamics of low-surface-tension liquids on two flat substrate surfaces by using reflection interference confocal microscopy. Spontaneous migration toward relatively larger droplets was first observed for microdroplets nucleated hydrophilic quartz surface. The moving showed a angle hysteresis ∼0.5°, which is much lower than values typical substrates and within...

A liquid drop resting on a soft solid deforms the surface at three-phase contact line. The deformation, also called "wetting ridge", varies in size from nanoscales to microscales, depending elasticity and thickness of layer. In this work, we probe how coating influences normal tangential deformation profiles induced by sessile using dual-wavelength reflection interference contrast microscopy. Furthermore, experimentally verify appropriate characteristic length scale, which closely describes...

Experimental investigation of dropwise condensation low-surface-tension liquids remains prone to error owing the imaging difficulties caused by typically low droplet height. Using reflection interference contrast microscopy in confocal mode, we demonstrate a noninvasive framework accurately capture this dynamics volatile with surface tension. The capability developed is demonstrated studying acetone, where it describes growth mechanism condensed microdroplets excellent spatiotemporal...
