The solar light redirecting glazing units may include two glazing substrates separated by an intervening space with a solar light redirecting layer disposed on one glazing substrate, and a visible light diffusing layer disposed on the other glazing substrate.

Abstract: A taillight article (100) including an optically clear light guide (110) having an light emission front surface (112) and an opposing rear surface (114) and a side surface (118) separating the front surface (112) and the rear surface (114) is described. A first light source (120) is configured to direct light into the side surface (118) and indicate a first signal-function. A plurality of light extraction features (116) are on or within the optically clear light guide (110) and are configured to direct light from the first light source (120) out through the emission surface (112). A light reflection element (130) is spaced apart from the rear surface (114) and defines a cavity (135) that is observable by a viewer.

Abstract: The present disclosure provides lamination transfer films and use of the lamination transfer films, particular in the fabrication of architectural glass elements, such as those used in Insulated Glass Units (IGUs). The lamination transfer films may be used to transfer functional layers and structures. The lamination transfer films may include a support film that can be removed during the transfer process, and the transferred materials are primarily inorganic. The resulting transferred structures on glass generally have high photo- and thermal-stability, and therefore can successfully be applied to the glass surfaces that are interior to the cavity within an IGU. The lamination transfer films can also be patterned such that macroscopic patterns of microoptical elements can be applied on a glass surface.

Abstract: The methods and compositions described herein are based, in part, on the discovery that the introduction of a disulfide bond into an integrin polypeptide by the substitution of at least one cysteine residue in the polypeptide permits stabilization of the integrin in a “closed/inactive” state. This stabilizing disulfide bond permits integrins to be screened for a candidate molecule that can bind to the closed state. In particular, this approach can be used to screen for agents that bind to the closed state of an integrin polypeptide, and are useful as therapeutic treatments to prevent integrin activation.

Abstract: Disclosed is a circular polarized antenna structure, comprising a main body, a protruding portion and a stopping portion, the stopping portion being formed between the main body and the protruding portion. The circular polarized antenna may be disposed to penetrate through the upper and lower surfaces of a base that has a radiation conductor and a grounding conductor disposed thereon respectively, the stopping portion abutting against the lower surface of the base to prevent the main body from coming loose and being detached from the base even if the protruding portion is subjected to a great impact or squeezing pressure caused by an external force coming from the lower surface upwards.
