A piezoelectric thread that includes a core thread; and a piezoelectric film wound around the core thread. The piezoelectric thread is constructed to generate a charge by energy imparted from outside of the piezoelectric thread.

A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.

Composites based on a polymer and a mixture of proteins derived from a MaSp (major ampullate spidroin) protein are provides. Further, methods for preparation of same, and method of use of the composites are provided.

Processes for making fibrous structures and more particularly processes for making fibrous structures comprising filaments are provided.

A method for manufacturing a polymer-based fibrous scaffold is disclosed. The method includes the following step: providing an electrospinning device comprising a collector; and injecting a polymer solution into the electrospinning device to produce a single jet fiber, wherein the single jet fiber is piled on the collector to form a fibrous scaffold.

Thermally stable absorbable fiber populations, i.e. fiber populations that do not undergo thermally induced crystallization, can be intermixed with thermally unstable fibers to yield a stabilizing effect without altering morphological properties of a fiber system. Via this, one may minimize thermally induced shrinkage and maintain physical properties of electrospun materials in the as-formed state.

A knitted fabric structure that includes a piezoelectric yarn having a piezoelectric material that produces a surface potential by input of an external force from an outside of the piezoelectric yarn; and an elastic yarn having stretchability knitted together with the piezoelectric yarn, wherein the piezoelectric yarn has a mixing ratio of 5% or more based on a whole of the knitted fabric structure.

The present disclosure relates to compositions, devices, and methods for delivery of protein therapeutics, e.g., intravitreal delivery of a protein therapeutic to the eye. In particular, the present disclosure describes drug-delivery devices for injection into the eye of a subject in need thereof comprising a capsule having a bi-layered wall and a therapeutic agent, wherein the therapeutic agent is initially present within a luminal space of the capsule. Methods of making and using these drug-delivery devices are also described.

Proposed are a composition for an eco-friendly filament using soybean hulls and a 3D printing eco-friendly filament manufactured by using the same. A manufacturing method of the 3D printing eco-friendly filament by using soybean hulls includes a first step of manufacturing soybean hull powder by grinding the soybean hulls, a second step of manufacturing a composition for an eco-friendly filament by adding biodegradable plastic resin to the soybean hull powder and mixing the biodegradable plastic resin with the soybean hull powder, and a third step of manufacturing the 3D printing eco-friendly filament by cooling the composition for an eco-friendly filament after extruding the composition for an eco-friendly filament through an extruder for filament formation. The composition for a safe and eco-friendly filament while discarded soybean hulls are used for resource utilization and the 3D printing eco-friendly filament manufactured by using the same are provided.
