Abstract: An optically structured element (1) for minimizing or preventing bird collisions, includes a carrier element (2), a high-reflectivity region (3), and a low-reflectivity region (4); which is distinguished in that a double cone reflectance difference of a first double cone reflectance of the high-reflectivity region (3) and a second double cone reflectance of the low-reflectivity region (4) is greater than or equal to 5% and a VIS transmission ratio of the first VIS transmittance and the second VIS transmittance is greater than or equal to 70% and less than or equal to 200%.

Abstract: A glazing unit is provided for producing an aesthetically pleasing effect. The glazing unit may include at least one polymer with a first structured surface to which a photonic structure is applied. The surface can reflect a first partial spectrum of incident electromagnetic radiation, and can transmit a second partial spectrum of incident electromagnetic radiation. A reflected proportion corresponds to a higher harmonic and is in a visible spectral range.

Abstract: A glazing unit is provided for producing an aesthetically pleasing effect, comprising or consisting of at least one pane, said pane having a first structured surface to which a three-dimensional photonic structure is applied and the average refractive index of the photonic structure being higher than approximately 1.6 or higher than approximately 1.8 or higher than approximately 1.95. A method of producing such a glazing unit and the use thereof is also provided.

Abstract: A solar receiver includes a wavelength selective coating comprising a first diffusion barrier layer, a metallic IR reflective layer, a solar absorptive layer, an anti-reflective layer, and/or a hard coat protective layer. Selective absorber coatings, which are characterized by a high solar absorption coefficient and low thermal emission, can be used to convert captured solar radiation into usable heat. In embodiments, more efficient selective coatings are provided that combine relatively high solar absorbance (e.g., greater than about 0.96) with relatively low thermal emittance (e.g., less than about 0.07 at 700° C.), and that are thermally stable above 600° C., for example, in outdoor conditions. The use of such coatings in a solar field may allow for an increase in the operating efficiencies thereof at operating temperatures of about 600° C. or greater.

Abstract: A device for capture and retention of various animals such as calves, pigs and the like for branding, castration or the like consisting of a formed, open and openable, resilient hooking end of a size to allow positioning about the rear leg of an animal and a rod of an extensible length to allow for manual use.
