Abstract: Nanostructured articles, materials for the nanostructured articles, and intermediate articles for use in making the nanostructured articles. The nanostructured articles can be formed on a flexible film and are useful for optical metasurface applications and possibly other applications. The articles can include nanoreplicated layers or pattern transfer layers of engineered nanostructures.

Abstract: The present disclosure relates to abrasive articles including conformable coatings, e.g. a hydrophilic coating, and polishing systems therefrom. The present disclosure provides an abrasive article including a ceramic body having an abrading surface and an opposed second surface, wherein the abrading surface of the ceramic body includes a plurality of engineered features each having a base and a distal end opposite the base and the ceramic body has a Mohs hardness of at least 7.5; a conformable metal oxide coating adjacent to and conforming to the plurality of engineered features, wherein the conformable metal oxide coating includes a first surface; and a conformable polar organic-metallic coating in contact with the first surface of the conformable metal oxide coating, wherein the conformable polar organic-metallic coating includes a chemical compound having at least one metal and an organic moiety having at least one polar functional group.

Abstract: A light control film is described comprising alternating transmissive regions and absorptive regions disposed between a light input surface and a light output surface. The absorptive regions have an aspect ratio of at least 30. In some embodiments, the alternating transmissive regions and absorptive regions have a transmission as measured with a spectrophotometer at a viewing angle of 0 degrees of at least 35, 40, 45, or 50% for a wavelength of the range 320-400 nm (UV) and/or at least 65, 70, 75, or 80% for a wavelength of the range 700-1400 nm (NIR). In another embodiment, the absorptive regions block light at the light input surface and light output surface and the maximum surface area that is blocked is less than 20% of the total alternating transmissive regions and absorptive regions. Also described are various optical communication systems comprising the light control films described herein and methods.

Abstract: A condensation management apparatus comprises a first microstructured film arranged to condense water vapor on a substantially vertical surface of a component. The first film comprises channels disposed on first and second major surfaces of the first film and dimensioned to support capillary movement of condensate. The channels have a channel axis substantially parallel with a longitudinal axis of the first film. The longitudinal axis of the first film is tilted at a tilt angle of at least 4 degrees with respect to an axis normal to a direction of gravity. Openings in the channels are disposed at one or both end edges of the first film. The openings provide condensate release locations of the first film. A second film is disposed over a portion of the first film. The second film attaches the first film to the substantially vertical surface of the component.

Abstract: A system and methods for sterilizing or disinfecting articles, particularly the hollow internal areas of medical instruments are disclosed. The system includes a plasma generator having an electrode, a shield, and a dielectric gap between the electrode and the shield. A source of electrical power is connected to the plasma generator for applying an electron energy density between the electrode and the shield. A source of gas comprising water vapor, oxygen and nitrogen provides a flow of gas between the electrode and the shield, to form a plasma containing acidic and/or oxidizing species. In the exemplary system, the temperature at the shield's surface is 0.05 eV/molecule of the gas. Also disclosed is a method for disinfecting an article contaminated with a bio-film or spores, by exposing the contaminated article to the plasma for an exposure time sufficient to achieve at least 2-log10 reduction in colony forming units.
