Stable water-in-oil emulsion is essential to digital PCR and many other bioanalytical reactions that employ droplets as microreactors. We developed a novel technology to produce monodisperse emulsion droplets with high efficiency and high throughput using a bench-top centrifuge. Upon centrifugal spinning, the continuous aqueous phase is dispersed into monodisperse droplet jets in air through a ...

silver sulfadiazine is used to prevent and treat infections of second- and third-degree burns. it kills a wide variety of bacteria. in this study silver sulfadiazine was used in gelatin based electro-spun nano-fibers with various drug to polymer ratios (0, 5, 10, 15 and 20 %). sem, edx and ftir analysis showed that the continuous, bead-free, fine fibers containing silver sulfadiazine as an anti...

The technique to fabricate nanofibrous mat by electro-spinning has been known for a long time. But the attempts to use the electospun nanofiber mats, also known as electro-spun nanofiber membranes (ENMs), for filtration purposes began only recently. Among many membrane filtration processes, air cleaning by the removal of dust particles has already been commercialized and the product has been in...

Anisotropic alignment of collagen fibres in musculoskeletal tissues is responsible for the resistance to mechanical loading, whilst in cornea is responsible for transparency. Herein, we evaluated the response of tenocytes, osteoblasts and corneal fibroblasts to the topographies created through electro-spinning and solvent casting. We also evaluated the influence of topography on mechanical prop...

Abstract Electronic fibers/textiles have great potential for applications in smart wearables due to their excellent flexibility, air permeability, and wearing comfort. However, it is still challenging produce reliable electronic textiles at low cost a large scale. Herein, we report spraying‐spinning process fabricating yarns with stability durability. Cotton sliver, which the raw material spinn...

The main objective of this work is the preparation nano-fibrous mats (NFM) from polyamide 6 (PA6) reinforced and functionalized by renewable proteinic waste examining their potential use for sorption heavy metal ions dyes wastewater textile plants. Two biopolymers; namely keratin (from wool combing) sericin degumming natural silk) were extracted regenerated. NFM prepared electro-spinning PA6/ b...

Summary Different methods of measuring cavitation resistance in fern petioles lead to variable results, particularly with respect the P 50 metric. We hypothesised that dictyostele structure affects air entry into xylem, and therefore impacts shape vulnerability curve. Our study examined this variation by comparing curves constructed on collected from evergreen deciduous ferns field, generated u...

We extend and generalise the string corrections to EM memory Type I superstring including spin effects. Very much as in simpler bosonic context, relevant are non-perturbative $\alpha'$, slowly decaying (as $1/R$) at large distances modulated retarded time $u=t-R$. For $N$ states first Regge trajectory they entail a sequence of derivatives wrt $u$ on `parent' $N=0$ amplitude. also briefly discus...
