A data generation method generates data for controlling an arrangement step in an imprint process that includes the arrangement step of arranging an imprint material on a substrate, a contact step of bringing the imprint material and a pattern portion of a mold into contact with each other, and a curing step of curing the imprint material. The method includes performing a first step of determining a plurality of first positions, based on information related to a boundary of the pattern portion in the substrate, as positions where the imprint material is to be arranged, and performing a second step of determining, after the first step, a plurality of second positions different from the plurality of first positions, as positions where the imprint material is to be further arranged.

An elastomeric article for sealing a container includes an elastomeric body having an external sidewall surface and an external crown surface and a first fluoropolymer film layer having an internal surface and an external surface. The internal surface of the first fluoropolymer film layer is laminated to an entirety of the external sidewall and crown surfaces of the elastomeric body. The external crown surface of the first fluoropolymer film layer includes a drug contact surface configured to contact a drug contained in the container and the external sidewall surface including a sealing surface for contacting an interior surface of the container. The external surface of the first fluoropolymer film layer is substantially free of striations.

Fixtures and related system and methods are disclosed. In accordance with an implementation, a method includes applying a resin onto a substrate and positioning the substrate on over a chuck of a base of a fixture. The method also includes moving a mold into engagement with the resin and curing the resin. The method also includes detaching the mold and the resin and, while detaching the mold and the resin, determining a detachment force applied as a function of a distance of detachment between the mold and the resin.

A method for the production of a structural die that has die structures for applying microstructures and/or nanostructures on substrates or soft dies, whereby the die structures are coated at least partially with a coating. In addition, the invention relates to a corresponding structural die as well as a device for the production of a structural die that has die structures for applying microstructures and/or nanostructures on substrates or soft dies, whereby the device has coating means for coating the die structures.

The present invention discloses polymer surfaces with T-shaped microstructure and their fabrication method and applications. The polymer surfaces with the T-shaped microstructure are characterized in that T-shaped microposts arrange orderly on them, and nanobulges arrange orderly on the top surfaces of the micronails of the T-shaped microposts. A flexible insert is designed and manufactured according to the geometry of the T-shaped microposts, and nanogrooves are manufactured on the cavity surface of an injection mold according to the geometry of the nanobulges on the top surfaces of the micronails. The flexible insert is mounted on the injection mold cavity. An injection molding machine is used to inject the molten polymer into the injection mold cavity. Then the polymer surfaces with the T-shaped microposts, on the top surfaces of the micronails of which the nanobulges arrange orderly, are molded. The polymer surfaces with the T-shaped microstructure exhibit robust Cassie-Baxter state and moderate surface adhesion to water droplets, and can be used for quantitative collection, lossless transportation or micromixing of microdroplets.

Devices and methods for using and manufacturing microstructure arrays having at least a detachable distal area are described.

A method for manufacturing at least one elastomeric article is provided. The method includes placing into a mold an assembly of an uncured elastomeric sheet, a first film fully covering the elastomeric sheet and a second film covering the first film, such that the second film is in contact with and positioned between the first film and an interior surface of the mold. The method further includes curing the assembly in the mold, such that the first film is laminated onto the elastomeric sheet thereby forming the at least one elastomeric article.
