The present disclosure provides a method for manufacturing a transparent ultra-thin film including the steps of (a) supplying different PUA precursors to two silicon masters, respectively, and then curing the PUA precursors by irradiation with ultraviolet ray, (b) separating a PUA mold formed by curing the different PUA precursors from the two silicon masters, (c) supplying perfluoropolyether (PFPE) precursor between the PUA molds, and then curing the PEPE precursor by irradiation with the ultraviolet ray, and (d) separating the PUA mold to prepare an ultra-thin film in which the PFPE precursor is cured, and a transparent ultra-thin film manufactured thereby.

The invention relates to the use of layer structures in the production of rotor blades for wind power plants, and to rotor blades for wind power plants.

Apparatus and method for applying discrete components of a first substrate to a second substrate includes a programmable servo motor having a shaft. The servo motor is programmed to rotate the shaft in a first phase and a second phase at a variable angular velocity in a single direction. The apparatus also includes a crank member connected with the shaft, a connector link connected with the crank member, and a tamper member connected with the connector link. When the shaft rotates in the first phase, the tamper member travels from a first position to a second position to displace a selected portion of the second substrate into contact with the discrete component.

Implanted medical devices need a mechanism of immobilization to surrounding tissues, which minimizes tissue damage while providing reliable long-term anchoring. This disclosure relates to techniques for patterning arbitrarily shaped 3D objects and to patterned balloon devices having micro-or nano-patterning on an outer surface of an inflatable balloon. The external pattern can provide enhanced friction and anchoring in an aqueous environment. Examples of these types of patterns are hexagonal arrays inspired by tree frogs, corrugated patterns, and microneedle patterns. The patterned balloon devices can be disposed between an implant and surrounding tissues to facilitate anchoring of the implant.

The present invention relates to a two-component polyurethane composition composed of at least one polyol, at least one polyisocyanate, and at least one emulsifier which is not homogeneously miscible with the at least one polyol. The present invention further relates to the use of this polyurethane composition as a binder for producing fiber composites, a method for producing these fiber composites, the fiber composites themselves, and use thereof.

Method for manufacturing a polyurethane foam by microcasting based on MDI (diphenylmethane diisocyanate) and on a polyol with a high ethylene oxide content, having an ethylene oxide content of greater than 50%, in which the following are mixed, under pressure, to form a foaming liquid precursor of polyurethane foam: a first reactive liquid, referred to as liquid A, comprising on the one hand a urethane prepolymer based on a first portion of the MDI and on a first portion of said polyol, and on the other hand the second portion of the MDI in the free state, said prepolymer being dissolved in this second portion of MDI in the free state; with a second reactive liquid, referred to as liquid B, comprising the second portion of said polyol and water as foaming agent,
characterized in that the amount of said polyol in the liquid B represents between 25% and 75% by weight of the total of said polyol; this method is advantageously used for casting a polyurethane foam into the cavity of a tyre casing.
