摘要: The present invention relates to compositions based on nanodispersions which are preferably further processed to electrospun fibers comprising such nanodispersions. The nanodispersions may optionally contain birch bark extract. The electrospun fibers can be used in particular for the treatment of wounds. For this purpose the compositions containing electrospun fibers are preferably applied as such or in a spray or a foam.

摘要: A method for manufacturing pellets from polymer, comprising: (1) melting polymer flakes in a first section of a melt processing unit to create a first single stream of polymer melt; (2) separating the first single stream of polymer melt into multiple streams of polymer melt by means of a separation element; (3) passing the multiple streams through a multiple stream section of said melt processing unit and exposing the multiple streams to a pressure within the multiple stream section of the melt processing unit as the multiple streams pass through the multiple stream section; (4) recombining the multiple streams into at least one combined stream of polymer melt; and (5) cooling the polymer melt and forming said pellets from the at least one combined stream. The intrinsic viscosity of the at least one combined stream may be determined and, in response, the chamber pressure within the multiple stream section adjusted.

摘要: Disclosed herein are electrospun fibrous matrix and its production method. The method mainly includes the steps of, mixing a first polymer and a drug to form a first mixture, and sonicating the first mixture until a plurality of microparticles are formed with the drug encapsulated therein; and mixing the plurality of microparticles with a second polymer to form a second mixture, subjecting the second mixture to a wet electrospinning process to form the electrospun fibrous matrix. The thus-produced electrospun fibrous matrix is characterized by having a plurality of first and second fibrils woven together, in which each second fibril has a plurality of drug-encapsulated microparticles independently integrated and disposed along the longitudinal direction of the second fibril. Also disclosed herein is a method for treating a wound of a subject. The method includes applying the present electrospun fibrous matrix to the wound of the subject.

The method of manufacturing the all-solid-state battery includes: (a) a step of forming a non-woven fabric having a fiber made of a resin; (b) a step of applying a slurry containing solid electrolyte particles onto the non-woven fabric; (c) a step of drying the slurry on the non-woven fabric by a heater; (d) a step of pressurizing the slurry on the non-woven fabric by a roller; (e) a step of forming a positive electrode member on one surface of the solid electrolyte membrane; and (f) a step of forming a negative electrode member on the other surface of the solid electrolyte membrane. The step (a) is a step of forming the non-woven fabric by making a resin containing a polar filler fibrous by a laser electrospinning method. By such a method, the all-solid-state battery (a laminated body of a positive electrode member, a solid electrolyte membrane, and a negative electrode member) can be efficiently manufactured.

摘要: A capillary type multi-jet nozzle is provided for fabricating high throughput nanofibers by an electrospinning technique. The capillary type multi-jet nozzle includes a cap system with one or more pores and a crew system with a screw groove system. The cap system and the crew system are connected through a cap and crew system. The pores in the cap system are customized in count based on a requirement. The angle between the pores is reduced to make multiple non-interfering and non-hindering jets in less time. A TEFLON® gasket is used for proper tightening and sealing of the cap system and screw system. The cap system includes knurling at an outer surface for grip. The capillary type multi-jet nozzle is made of a conducting material to with stand a high voltage and is fabricated using micro-machining process.
