Very thin liquid jets can be obtained using electric field, whereas an electrically-driven bending instability occurs that enormously increases the jet path and effectively leads to its thinning by very large ratios, enabling the production of nanometre size fibres. This mechanism, although it was discovered almost one century ago, is not yet fully understood. In the following study, experiment...

A proton exchange membrane has been developed for direct methanol fuel cell (DMFC). The nanofiber network composite membranes were prepared by interconnected network of Nafion (perfuorosulfonic acid) nanofibers that have been embedded in an uncharged and inert polymer matrix, by electro-spinning. The spinning solution of Nafion with a low concentration (1 wt% compared to Nafion) of high molecul...

Adsorption and assembly of colloidal particles at the surface of liquid droplets are at the base of particle-stabilized emulsions and templating. Here we report that electrohydrodynamic and electro-rheological effects in leaky-dielectric liquid drops can be used to structure and dynamically control colloidal particle assemblies at drop surfaces, including electric-field-assisted convective asse...

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...

In order to meet the increasing demand for nanofibers and overcome disadvantages of traditional electrospinning technology, it is necessary research an device that can produce efficiently. this paper, a free surface was improved, spherical section developed prepare high-quality polyacrylo-nitrile in batches. Meanwhile, MAXWELL 3-D software used simulate electric field distribution electro-spinn...

We have developed a real-time terahertz time-domain polarization analyzer by using 80-MHz repetition-rate femtosecond laser pulses. Our technique is based on the spinning electro-optic sensor method, which we recently proposed and demonstrated by using a regenerative amplifier laser system; here we improve the detection scheme in order to be able to use it with a femtosecond laser oscillator wi...

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...
