Abstract: Systems including one or both of a light emitter or a light receiver and an optical filter adjacent one or both of the light emitter or the light receive are described. The optical filter includes a wavelength selective scattering layer that scatters near-infrared light less than visible light. The wavelength selective scattering layer includes a plurality of particles. The plurality of particles have an imaginary refractive index less than 10.

Abstract: A nanocomposite is provided including nonspherical silica nanoparticles dispersed in a curable resin or a curing agent, where the nanocomposite contains less than 2% by weight solvent. A composite is also provided including from about 4 to 70 weight percent of nonspherical silica nanoparticles dispersed in a cured resin, and a filler embedded in the cured resin. Further, a method of preparing a nanoparticle-containing curable resin system is provided including mixing from 10 to 70 weight percent of aggregated silica nanoparticles with a curable resin and optionally a dispersant, a catalyst, a diluent, a surface treatment agent, and/or a curing agent, to form a mixture. The mixture contains less than 2% by weight solvent. The method also includes milling the mixture in an immersion mill containing milling media to form a milled resin system including nonspherical silica nanoparticles dispersed in the curable resin.

Abstract: A nanocomposite is provided including layered nanoparticles and a dispersant dispersed in a curable resin, where the nanocomposite contains less than 2% by weight solvent. A composite is also provided including from about 1 to 70 weight percent of layered nanoparticles, and a dispersant, dispersed in a cured resin, and a filler embedded in the cured resin. Further, a method of preparing a nanoparticle-containing curable resin system is provided including mixing from 1 to 70 weight percent of aggregated layered nanoparticles with a curable resin and a dispersant to form a mixture. The mixture contains less than 2% by weight solvent. The method also includes milling the mixture in an immersion mill containing milling media to form a milled resin system including layered nanoparticles dispersed in the curable resin.

Abstract: A nanocomposite is provided including spherical pyrogenic silica nanoparticles dispersed in a curable resin or a curing agent. The nanocomposite contains less than 2% by weight solvent and less than 0.5% by weight dispersant based on the nanoparticle weight. A composite is also provided including from about 4 to 70 weight percent of spherical pyrogenic silica nanoparticles dispersed in a cured resin, and a filler embedded in the cured resin. Optionally, the composite further contains a curing agent. Further, a method of preparing a nanoparticle-containing curable resin system is provided including mixing from 10 to 70 weight percent of aggregated spherical pyrogenic silica nanoparticles with a curable resin to form a mixture. The mixture contains less than 2% by weight solvent and less than 0.5% by weight dispersant based on the nanoparticle weight. The method also includes milling the mixture in an immersion mill containing milling media to form a milled resin system including silica nanoparticles dispersed in the curable resin.
