The present invention generally relates to a system and method for using a volatile organic compound (VOC) free low radiant flux LED UV curable composition, and more particularly to unique and novel uses of the composition such as one or two or more of a fire retardant, clear coat, composite material, resin, top coat, improved holdout coating, a sealant coat, and combinations of the same.

A method for manufacturing a mold includes (a) anodizing an aluminum substrate at a voltage of 60 V to 120 V in an electrolytic solution in which two or more species of acid are mixed, and forming an oxide film having a plurality of minute holes on a surface of the aluminum substrate; and (b) removing at least a portion of the oxide film. The electrolytic solution used in (a) satisfies the relation (D1)/2<D2, where D1 is the current density when the aluminum substrate is anodized under the same conditions as in (a) in an electrolytic solution of only the acid (A) having the highest acid dissociation constant (Ka) of the two or more species of acid, and D2 is the current density when the aluminum substrate is anodized under the same conditions (a) in the same electrolytic solution as that of (a).

A body-mountable device may include a first polymer layer, a second polymer layer, and a structure that includes a sensor between the first and second polymer layers. Fabricating the body-mountable device may involve providing a respective surface layer on each of one or more molding pieces, forming a first polymer layer, positioning the structure on the first polymer layer and then forming, between molding pieces, the second polymer layer over the structure positioned on the first polymer layer. The surface layer of each molding piece may facilitate release of the polymer layer or fabricated body-mountable device without disruption to the embedded structure.

A method for manufacturing an imprint mold which can prevent accumulation of the transferring resin at the joining portion of the film mold is provided. A method for manufacturing an imprint mold, including a winding step to wind a resin film mold onto a cylindrical transferring roll, the resin film mold being provided with a reverse pattern of a desired fine concave-convex pattern and the resin film mold being wound onto the transferring roll so that a gap without the reverse pattern is provided at a butting portion of both ends of the resin film mold; a resin filling step to fill a resin composition into the gap; and a pattern forming step to form a pattern substantially the same as the reverse pattern onto the resin composition, is provided.

A semipermeable ultrathin polymer membrane is a microfluidic device that comprises a substantially optically transparent polymer film having a surface area to thickness ratio of at least 1,000,000:1, and an array of precisely spatially ordered pores of a user-selected diameter defined therethrough. Such membranes can be fabricated by providing a mold having a patterned array of nanoholes femtosecond laser ablated in a surface thereof; applying a first polymer solution onto the mold surface so that the first polymer solution infiltrates the nanoholes; allowing the first polymer solution to dry and form a replica of the mold having a plurality of freestanding nanoneedles extending from a surface of the replica; removing the replica from the mold; coating the replica surface with a second polymer solution; drying the second polymer solution to form a porous polymer film; and dissolving the replica in a solvent to release the film from the replica as a semipermeable ultrathin polymer membrane. Also disclosed are multi-chambered microfluidic devices for studying cell biology in vitro that incorporate one or more such semipermeable ultrathin polymer membranes.
