Post-draw tower coating curing provides additional curing to an optical fiber coating after the fiber exits the bottom or output end of an optical fiber draw tower. A system may include a draw tower and a coating curing unit. The draw tower has at least one coating applicator. The coating curing unit may be located along a fiber path between the output end of the draw tower and a fiber takeup system.

The present invention relates to a novel process for the production of coated filaments for subsequent application as print in extrusion-based 3D printers, e.g. FDM printers (fused deposition modelling printers). The filaments are coated in a separate process outside of the printer, and can also be used in a conventional extrusion printer. The present invention further relates to the coating device for application of the coating to the filament and to a roll containing the coated filaments.

A coating for a medical device or appliance may include a fluoropolymer and a polyimide. Such coatings may provide a lubricious exterior surface that facilitates insertion or displacement of a medical device in a body lumen. Some coatings that include a fluoropolymer and a polyimide may, among other functions and characteristics, provide increased strength and/or durability relative to some other coatings.

A method of treating a tubular medical device with a biomolecule comprises the steps of: a) providing a polyolefin tubular substrate forming a tubular medical device; b) cleaning the tubular polyolefin substrate; c) exposing the tubular polyolefin substrate to a reactive gas containing at least one of acrylic acid and siloxane and to plasma energy to yield a plasma-deposited coating on at least one surface of the tubular polyolefin substrate; and d) attaching a biomolecule to the polyolefin substrate following formation of the plasma-deposited coating on at least one surface of the tubular polyolefin substrate, and wherein the biomolecule is at least one of an antibacterial agent, antimicrobial agent, anticoagulant, heparin, antithrombotic agent, platelet agent, anti-inflammatory, enzyme, catalyst, hormone, growth factor, drug, vitamin, antibody, antigen, protein, nucleic acid, dye, a DNA segment, an RNA segment, protein, and peptide.

A fiber material contains an assembly of a plurality of nanofiber coated polymer fibers in which a polymer fiber serving as a core fiber is coated with polymer nanofibers, in which the polymer fibers and the polymer nanofibers are fusion-bonded and two or more of the polymer fibers are fusion-bonded to each other in at least one portion.

A system and method for monitoring and operating one or more light emitting devices is disclosed. In one example, light intensity within a dual elliptical reflecting chamber is sensed and operation of a fiber curing system is adjusted in response to an amount of sensed light energy.

Provided herein is a nanoscale material assembly made up of a plurality of nanoscale structures with a crosslinked polymer thermally deposited on the structures. Also disclosed are methods for preparing the nanoscale material assembly with a deposited crosslinked polymer. Further disclosed are various conditions and materials that when used in the preparation of the nanoscale material assemblies further enhance their mechanical properties. In some embodiments, the nanoscale material assemblies can be either nanoscale yarn assemblies or nanoscale sheet assemblies.

An irradiation system is provided. The irradiation system includes a plurality of LED arrays, each of the LED arrays including a plurality of LED light producing elements. The irradiation system also includes a target area, the target area being adapted to receive light energy from each of the plurality of LED arrays. The plurality of LED arrays are positioned with respect to one another such that they surround the target area of the irradiation system.

A method of manufacturing a natural composite material multilayer structure includes: manufacturing a felt layer; spraying a thermosetting resin onto one surface or both surfaces of the felt layer; forming an intermediate layer of the sprayed thermosetting resin to form a composite material; heat-pressing the composite material through a heated mold; and cold-pressing the heat-compressed composite material.
