Abstract: A water-based solvent-free and IR reflecting surface treatment composition is disclosed. In one or more embodiments, the composition includes: (1) a base comprising (a) 30 to 60% by weight of an acrylic resin; (b) 1 to 10% by weight of an alkyd resin; (c) 0.1 to 2% by weight of a polyolefin; (d) 0.1 to 1% by weight of an ammonium salt; (e) less than 0.1% by weight of a preservative; (f) water such that base reaches 100 % by weight; and (2) a paste comprising (i) metal oxides having a mean particle size between 0.05 and 5 ?m; and (ii) a polymeric binder.
Abstract: The invention provides an article of manufacture, and methods of designing and making the article. The article permits or prohibits waves of energy, especially photonic/electromagnetic energy, to propagate through it, depending on the energy band gaps built into it. The structure of the article may be reduced to a pattern of points having a hyperuniform distribution. The point-pattern may exhibit a crystalline symmetry, a quasicrystalline symmetry or may be aperiodic. In some embodiments, the point pattern exhibits no long-range order. Preferably, the point-pattern is isotropic. In all embodiments, the article has a complete, TE- and TM-optimized band-gap. The extraordinary transmission phenomena found in the disordered hyperuniform photonic structures of the invention find use in optical micro-circuitry (all-optical, electronic or thermal switching of the transmission), near-field optical probing, thermophotovoltaics, and energy-efficient incandescent sources.

Abstract: Described herein are novel azo-benzene type chromophores. The chromophores are useful in photochromic compositions comprising a polymer matrix and a chromophore, wherein the chromophore is a novel azo-benzene type structure. The photochromic composition is photoresponsive upon irradiation by at least one wavelength of laser light across the visible light spectrum. Photochromic devices which comprise the novel azo-benzene type chromophore compound show significantly higher photoinduced birefringence, higher diffraction efficiency, and brighter images than devices that comprise well known azo-benzene chromophores. The photochromic composition may include a liquid crystal.
