Disclosed is a process for forming films, fibers, and beads comprising a chitinous mass, for example, chitin, chitosan obtained from one or more biomasses. The disclosed process can be used to prepare films, fibers, and beads comprising only polymers, i.e., chitin, obtained from a suitable biomass, or the films, fibers, and beads can comprise a mixture of polymers obtained from a suitable biomass and a naturally occurring and/or synthetic polymer. Disclosed herein are the films, fibers, and beads obtained from the disclosed process. This Abstract is presented solely to aid in searching the subject matter disclosed herein and is not intended to define, limit, or otherwise provide the full scope of the disclosed subject matter.

Octaaminonaphthalene and a method of synthesizing octaaminonaphthalene are described. A two-dimensional coordination polymer and a method of synthesizing the two-dimensional coordination polymer are described. The two-dimensional coordination polymer includes ligands including anchorage sites, and metal linkers, each metal linker including a metal and an organic moiety. Each metal linker is coupled to two ligands via the anchorage sites. Synthesizing the two-dimensional coordination polymer includes contacting a first liquid precursor with a second liquid precursor at an interface, reacting the metal linker and the water-soluble ligand to yield a two-dimensional coordination polymer at the interface, and removing the two-dimensional coordination polymer from the interface.

Synthesizing a metal-organic-framework includes combining a first solution and a second solution to yield a synthetic medium. The first solution typically includes a solvent, an inhibitor, a metal capping agent, a ligand, and a metal source, and the second solution typically includes a deprotonating agent and a buffer. The metal and the ligand are reacted in the synthetic medium to yield a two-dimensional metal-organic-framework in the form of a nanosheet, and the two-dimensional metal-organic-framework is removed from the synthetic medium. The two-dimensional metal-organic framework has an aspect ratio of at least 300 or at least 1000.
摘要:
Forming a two-dimensional polymeric sheet includes translating a portion of a flexible substrate through a first liquid precursor to coat the portion of the flexible substrate with the first liquid precursor, thereby yielding a precursor-coated portion of the flexible substrate. The precursor-coated portion of the flexible substrate is translated through an interface between the first liquid precursor and a second liquid precursor, thereby reacting the first liquid precursor on the precursor-coated portion of the flexible substrate with the second liquid precursor to yield a polymer-coated portion of the flexible substrate.
摘要:
In some embodiments, an apparatus includes a formation member that defines a passageway configured to receive therein at least a portion of an optical fiber that includes a stripped portion to be recoated. The passageway defines at least in part a recoat cross-sectional width of the stripped portion of the optical fiber to be recoated. A nozzle is coupled to the formation member and configured to dispense a recoat material into the passageway when the nozzle is moved relative to the stripped portion of the optical fiber when the stripped portion of the optical fiber is disposed at least partially within the passageway such that the recoat material is dispensed on and surrounds the stripped portion of the optical fiber. In some embodiments, the apparatus includes a controller that can control the flow rate of the recoat material dispensed by the nozzle.
