Abstract: Devices are provided, including a housing defining at least one window, a broadband UVC light source, and a multilayer article positioned within the housing. The multilayer article includes an absorbent layer and an ultraviolet mirror containing at least a plurality of alternating first and second optical layers. The absorbent layer absorbs and/or scatters ultraviolet light having a wavelength between at least 230 nanometers (nm) and 400 nm. The ultraviolet mirror reflects ultraviolet light in a wavelength range from 190 nm to 240 nm. Methods of disinfecting a material are also provided, including obtaining a device and directing ultraviolet radiation through the window, and exposing the material to the ultraviolet radiation for a time sufficient to achieve a desired degree of disinfection of the material. Systems and computing devices including the device are also provided.

Abstract: A composite cooling film (100) comprises an antisoiling layer (160) secured to a first major surface of a reflective microporous layer (110). The reflective microporous layer (110) comprises a first fluoropolymer and is diffusely reflective of electromagnetic radiation over a majority of wavelengths in the range of 400 to 2500 nanometers. The antisoiling layer (160) has an outwardly facing antisoiling surface (162) opposite the micro-voided polymer film.

Abstract: A hybrid solar window comprises: at least one glazing; a wave-length-selective solar mirror positioned to reflect IR toward an IR absorbing element. The IR absorbing elements comprises a conduit having a respective fluid inlet and fluid outlet, and an IR absorbing compound, wherein the IR absorbing compound is in thermal communication with the conduit. The wavelength-selective solar mirror has an average visible light transmittance of at least 50 percent and an average IR reflectance of at least 50 percent over the wavelength range of 850 to 1150 nanometers, inclusive. The IR absorbing element is configured to transfer thermal energy to a heat transfer fluid circulating through the conduit, wherein the IR absorbing element has an average visible light transmittance of at least 30 percent, and wherein each IR absorbing element has an average IR absorptance of at least 50 percent over the wavelength range 850 to 1150 nanometers, inclusive. Certain IR absorbing elements are also disclosed.

Abstract: Provided are surfacing films that have a surface layer having opposed first and second major surfaces, the first major surface comprising a fluoropolymer surface and the second major surface optionally comprising a nanostructured surface. A printed layer can be disposed on the second major surface and can be at least partially embedded in the nanostructured surface, if present. As a further option, the fluoropolymer surface can be microreplicated to provide a frictional surface and/or provide aerodynamic drag reduction on aircraft structures. Optionally, the delamination peel strength of the surface layer from the remaining layers can be greater than the tensile strength of the surface layer.
