Researchers have developed a hand-held device that produces non-woven nanofiber (NF) mats in the absence of electrical forces. This device can do melt and solution spinning and since it does not require electric fields, it broadens the variety of materials that can be spun into NFs. The technology was recently introduced as a method that through centrifugal forces drives the material through a set of designed orifices within a spinneret. It may provide an opportunity to produce bioactive NF mats from different biomaterial solutions for wound dressings and hemorrhage control. The device has the ability to produce NFs from organic and inorganic solutions and melt for applications such as filtration, textiles, aerospace and aeronautics industries and additional applications as well. This project will look into further establishing a proof of concept for the technology.The development of a portable device which can produce a high yield in seconds and does not need dielectric solutions or any applied electrostatic field in situations where soldier/civilian safety is crucial and has the potential to open new doors for hemostatic materials and systems. Materials produced by this device can be used for the healing of wounds and for the treatment of active deep wounds as well as active large surface and shallow wounds provides potential benefits to soldier and civilian trauma/surgery procedures.

研究人员开发了一种手持设备，可以在没有电力的情况下生产非织造纳米纤维垫。这种设备可以进行熔融纺丝和溶液纺丝，由于它不需要电场，它拓宽了可以纺制成纤维的材料的种类。这项技术是最近推出的一种方法，通过离心力驱动材料通过喷丝板内的一组设计好的孔口。这可能为从不同的生物材料溶液中生产用于伤口敷料和出血控制的生物活性NF垫提供机会。该设备能够从有机和无机溶液中生产非金属氧化物，并将其熔化，用于过滤、纺织、航空航天工业和其他应用。该项目将寻求进一步建立该技术的概念验证。开发一种便携式设备，该设备可以在几秒钟内产生高产量，并且在士兵/平民安全至关重要的情况下不需要介电解决方案或任何应用静电场，并且有可能为止血材料和系统打开新的大门。该设备生产的材料可用于伤口愈合和治疗活动的深部伤口以及活动的大型和浅表伤口，为士兵和平民的创伤/外科手术提供了潜在的好处。
