The present invention is based on the identification of a cohort of polyurethane block copolymers that are particularly suited for use in pharmaceutical polymeric drug-device units and which offer improved control of drug release. In particular, there is provided a polymeric drug-device unit comprising a polyurethane block copolymer obtainable by reacting together a poly(alkylene oxide); a difunctional compound; a difunctional isocyanate; and optionally a block copolymer comprising poly(alkylene oxide) blocks; and quinagolide as a pharmaceutically active agent. The drug-device units may find application in the treatment and/or prevention of endometriosis.

Provided herein are methods, compositions, devices, and systems for the 3D printing of biomedical implants. In particular, methods and systems are provided for 3D printing of biomedical devices (e.g., endovascular stents) using photo-curable biomaterial inks (e.g., or methacrylated poly(diol citrate)).

Provided is a resin for nanoimprinting, which is capable of preventing removal of a transfer-receiving resin from a substrate when a mold is separated during nanoimprinting, and which is also capable of transferring a pattern on a mold to a transfer-receiving resin with high accuracy during thermal nanoimprinting, while improving the throughput. A resin for nanoimprinting, which is represented by formula (1). ##STR00001## (In the formula, each of R.sub.1-R.sub.5 independently represents —H or —OH, and at least one of the R.sub.1-R.sub.5 moieties represents —OH; R.sub.6 represents a linear, branched or cyclic alkyl group having 1-20 carbon atoms, an aryl group having 6-20 carbon atoms or an aralkyl group having 7-20 carbon atoms; X represents an amide or an ester; Y may be absent, or represents an amide or an ester; P represents an integer of 1-10; and each of m and n represents an integer of 1 or more.)

Provided is a display apparatus for a three-dimensional (3D) head-up display (HUD), the display apparatus including a transparent substrate, a polarizing film layer provided on the transparent substrate, and a lenticular lens provided on the polarizing film layer opposite to the transparent substrate, wherein the lenticular lens includes an adhesive layer, a base substrate provided on the adhesive layer, and a pattern layer provided on the base substrate opposite to the adhesive layer.

A method of making a molded product. The method includes obtaining a mold having a cavity defined by interior surfaces and applying a gelcoat into the mold. The method further includes at least partially curing the gelcoat within the mold, dispensing a viscous polymeric material into the mold, and curing the polymeric material while the polymeric material is sandwiched between the gelcoat.

The present invention relates to a creamy substance, which is configured to be discharged from a squeezing tool to produce a decorative body-formed toy, and contains a resin and a starch and has transparency.

The present invention relates to a novel process for the production of novel fibre-reinforced profile materials filled with a rigid foam core, especially a PMI foam core. In particular, the present invention relates to a novel process which, in various versions, provides a particularly high throughput and allows a very wide range of shaping options. One step here continuously produces a complex fibre-reinforced profile material and simultaneously inserts the rigid foam core into same. In addition, in the same process step, very good binding of the rigid foam core to the fibre-reinforced profile material is assured. Shaping further takes place in two or more moulds simultaneously to achieve a particularly high throughput and simultaneously produce profile materials differing in shape.

The present invention relates to a microneedle comprising a plurality of portions, wherein the plurality of portions comprise a distal end portion and a proximal end portion, at least two of the plurality of portions are made of different polymers, and the distal end portion is made of at least one polymer with high swellability and high viscoelasticity.

This application relates to a method of edge sealing for a secondary lithium battery, including: (1) drawing a 3D model of a battery edge of a secondary lithium battery, and inputting it into a 3D printer; (2) positioning the secondary lithium battery in a 3D printing area, and fixing a relative position of the secondary lithium battery in the 3D printing area; (3) stimulating, by the 3D printer, the battery edge according to the 3D model and setting a printing path; (4) adding edge sealing glue in a printing head of the 3D printer, the printing head moves according to the set printing path and meantime performs at least one time of printing, so that printed edge sealing glue covers the battery edge; (5) solidifying the edge sealing glue. The method of edge sealing of this application has broader application, which can be applied to batteries of any shape.

A mold release processing method according to an embodiment of the present invention includes the steps of: (a) providing a mold releasing agent, including a fluorine-based silane coupling agent and a solvent, and a mold of which the surface has a porous alumina layer; (b) applying the mold releasing agent onto the surface; and (c) heating, either before or after the step (b), the surface to a temperature not less than 40° C. and less than 100° C. in an ambient with a relative humidity of 50% or more.
