The invention relates to an electrode containing reduced graphene oxide nanofiber surface (25) with increased mechanical stress resistance, produced by electrospray method to increase efficiency by using in piezoelectric nanogenerators (40) with graphene electrodes.

A manufacturing method of a meltblown fiber membrane includes the following step. A meltblown film is made to pass between a first pressing roller and a second pressing roller, such that a calendering process is performed on the meltblown film, in which the meltblown film includes a plurality of meltblown fibers, each of the meltblown fibers includes a high-fluidity polyester and a modified polyester, a melt index of the high-fluidity polyester under a temperature of 230? C. ranges from 350 g/10 min to 550 g/10 min, a melt index of the modified polyester under a temperature of 230? C. ranges from 200 g/10 min to 400 g/10 min, and a roller temperature of each of the first pressing roller and the second pressing roller ranges from 100? C. to 155? C.

Aspects of the disclosure relate to synthetic tissue or organ scaffolds and methods and compositions for promoting or maintaining their structural integrity. Aspects of the disclosure are useful to prevent scaffold damage (e.g., delamination) during or after implantation into a host. Aspects of the disclosure are useful to stabilize tissue or organ scaffolds that include electrospun fibers.

A biofabricated material containing a network of crosslinked collagen fibrils is disclosed. This material is composed of collagen which is also a major component of natural leather and is produced by a process of fibrillation of collagen molecules into fibrils, crosslinking the fibrils and lubricating the crosslinked fibrils. Unlike natural leathers, this biofabricated material exhibits non-anisotropic (not directionally dependent) physical properties, for example, a sheet of biofabricated material can have substantially the same elasticity or tensile strength when stretched or stressed in different directions. Unlike natural leather, it has a uniform texture that facilitates uniform uptake of dyes and coatings. Aesthetically, it produces a uniform and consistent grain for ease of manufacturability. It can have substantially identical grain, texture and other aesthetic properties on both sides distinct from natural leather where the grain increases from one side (e.g., distal surface) to the other (proximal inner layers).

A nonwoven web comprising a layer of polymeric fibers, wherein, based on the total number of polymeric fibers, at least 10% the polymeric fibers in said layer are coarse fibers having a fiber diameter of 4 m or more, and at least 10% of the polymeric fibers in said layer are fine fibers having a fiber diameter of 2 m or less. Also described herein is a method for making the nonwoven web, comprising melt-blowing a polymer mixture comprising two immiscible or partially miscible polymers.

A fiber assembly according to one embodiment of the present disclosure includes a fiber. The fiber includes a core part that contains a coloring compound, a photothermal conversion material, and a color developer/reducer, and a sheath part that covers the core part and has a heat-insulating property.

A wipe includes a cleansing composition disposed on a cloth. The cleansing composition can include an antiseptic, a humectant, an emollient, a surfactant, and a monohydric alcohol. A wipe can be made by preparing a cleansing composition and disposing the cleansing composition on a cloth. Two or more wipes may be included in a sealed package to maintain the sterile state of the wipes. A method of disinfecting skin can include applying a wipe to skin.

Fabrics are provided that include mono-component staple fibers, a first group of split staple fibers comprising a first polymeric material, and a second group of split staple fibers comprising a second polymeric material that is different than the first polymeric material. The mono-component staple fibers, the first group of split staple fibers, and the second group of split staple fibers are physically entangled together to define a consolidated nonwoven. The fabrics may be physically entangled by hydroentanglement.

Filter media comprising a filtration layer comprising synthetic fibers (e.g., pleatable backer layer) and related components, systems, and methods associated herewith are provided. In some embodiments, the filtration layer comprising synthetic fibers may be a non-woven web comprising a blend of coarse and fine diameter fibers. The filtration layer comprising synthetic fibers may be designed to have desirable performance properties without compromising certain mechanical properties, such as the pleatability of the media. In some embodiments, a filter media, described herein, may comprise the filtration layer comprising synthetic fibers and an efficiency layer. Filter media, as described herein, may be particularly well-suited for applications that involve filtering air, though the media may also be used in other applications.
