Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.

A fiber manufacturing method includes the following steps of: dissolving a polymer in a solvent to obtain a polymer solution; spraying the polymer solution into a liquid heated to a boiling point of the solvent or higher, and evaporating the solvent to precipitate a fibrous polymer in a sealed precipitation tank, the liquid being immiscible with the polymer and the solvent; conveying the precipitated fibrous polymer in a liquid from the precipitation tank; water-rinsing the fibrous polymer conveyed in the liquid in the conveying step in a sealed water-rinsing tank; conveying the water-rinsed fibrous polymer in a liquid from the water-rinsing tank; and cooling and condensing solvent gas that is generated in the spraying step and the water-rinsing step.

The present invention is to provide a full-frame adhesive anti-fog film structure, comprising: an anti-fog film, which has a front side and a back side opposing the front side; and an adhesive, which is disposed at an edge of the back side and arranged along the edge so as to be frame-shaped. The anti-fog film of the present invention is attachable to a planar, cylindrical or spherical lens through the full frame-shaped adhesive so that not only can the anti-fog film be fully attached to the lens but the full attachment of film also prevents bubbles from forming between the two attached surfaces. Also, an airtight space is formed between the full-frame adhesive anti-fog film structure and the lens to stop heat transfer and prevent fog from being formed, so as to not only provide good vision to users but also reduce the chance that the user will fall prey to an accident if the user's view is blocked.

Capsule shells and coatings can be prepared from an aqueous composition comprising a) at least 20 percent, based on the total weight of the aqueous composition, of a dispersed esterified cellulose ether comprising (i) groups of the formula C(O)RCOOA or (ii) a combination of aliphatic monovalent acyl groups and groups of the formula C(O)RCOOA, wherein R is a divalent aliphatic or aromatic hydrocarbon group and A is hydrogen or a cation, b) from 0.05 to 20 percent of a salt of a fatty acid, based on the weight of the dispersed esterified cellulose ether, and c) from 0.01 to 10 percent of an anionic surfactant comprising a sulfate or sulfonate group, based on the weight of the dispersed esterified cellulose ether.

A bite block for use in a mouth of a patient to hold the mouth in a spaced-apart position that includes a condensed fiber block having a predetermined length suitable for being inserted into the mouth of the patient and positioned between upper and lower molars and a wrapper yarn repeatedly wrapped around the block along its length. An adhesive strand in the wrapper yarn is positioned on an outer surface of the fiber to maintain the block in its condensed state.

The present disclosure is directed to laminated articles, such as articles for food and beverages, that are biodegradable and/or paper recyclable. The articles include a substrate comprising a film layer. The film layer is formed from a film made from biodegradable and/or paper recyclable polymer materials. The film layer is resistant and/or impermeable to liquids The article is capable of being frozen and/or heated using, for instance, a microwave oven without delaminating.

A melt-processable, biodegradable cellulose acetate is disclosed. The melt-processable, biodegradable cellulose acetate of the present invention is characterized by a heated intrinsic viscosity (HIV) of at least 0.9. Also disclosed m is a stabilized cellulose acetate which may be characterized by a metals-to-sulfur molar ratio M/S of at least 1.35, wherein the M is the molar sum of metals selected from the group consisting of calcium, magnesium, potassium, sodium and combinations thereof and S is moles sulfur. Melt-processable, biodegradable cellulose acetate compositions; a melt-processable, biodegradable, cellulose acetate melt; and melt-formed articles are also described.
