APPARATUS, SYSTEM AND METHOD FOR MAKING A CARBON NANOMATERIAL FIBER AND TEXTILES FROM CARBON DIOXIDE AND MATERIALS AND MATERIALS AND PRODUCTS THEREOF
Embodiments of the present disclosure relate to a process for making a carbon nanomaterial fiber product and/or textile product. Such products may have new and/or enhanced properties as compared to similar products and, according to the embodiments of the present disclosure, it is less expensive to make.
FIBER DEPOSIT PRODUCTION METHOD, MEMBRANE PRODUCTION METHOD, AND MEMBRANE ADHESION METHOD
A fiber collection tool for collecting a fiber spun by electrospinning is described. The fiber collection tool has a size holdable by the hand of a user, and includes, in its interior, an electroconductive section. Preferably, the fiber collection tool further includes a surface section outside the electroconductive section. In a fiber deposit production method, a user collects, with the fiber collection tool, a fiber spun by the user by performing electrospinning using an electrospinning device having a size holdable by the hand of the user, and thereby produces a film including a deposit of the fiber on a surface of the fiber collection tool. The fiber collection tool, having the deposit formed thereon, is pressed against a surface of an object, and the deposit is transferred onto the surface of the object, to form a film including the fiber deposit on the surface of the object.
Medical material produced using collagen and method for producing same
Disclosed is a medical material manufactured using collagen and a method of manufacturing the same. The method includes (1) preparing collagen using distilled water as a solvent, (2) filling a syringe with the prepared collagen and then spinning the collagen through a syringe needle, (3) immediately immersing the spun collagen in a cross-linking solution, which is a mixture including therein a hyperosmotic agent and a cross-linking agent mixed with each other, (4) removing and then washing the collagen after cross-linking is completed, and (5) removing and then drying the collagen after the washing is completed. When the collagen is spun and processed into the form of a thread and the spun thread is then cross-linked, the cross-linked collagen thread has increased strength compared to before cross-linking, and the shape thereof is retained in an aqueous solution.
Silica fiber compositions and methods of use
Embodiments of the invention include silica fiber compositions useful for treatment of animal wounds and tissue, as well as for other applications in industry. The fiber compositions may be formed via electrospinning of a sol gel produced with a silicon alkoxide reagent, such as tetraethyl ortho silicate, alcohol solvent, and an acid catalyst.
DEVICE, SYSTEMS, AND METHODS OF APPLYING A TREATMENT SOLUTION TO A TREATMENT SITE

ELECTROSPUN FIBROUS MATRIX, ITS PREPARATION METHOD AND USES THEREOF
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 encompassed in the present disclosure 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 to accelerate wound healing.
