Article including a non-light-emitting variable transmission device and a coating
An article can include a non-light-emitting, variable transmission device and a coating disposed between the non-light-emitting, variable transmission device and an ambient outside the article. In an embodiment, the article has a ΔE of at most 6.5. In another embodiment, the coating includes a plurality of layers including a first layer having a refractive index of at least 2.2 and a thickness of at least 10 nm. The coating can be used to help reduce color differences seen when the non-light-transmitting, variable transmission device is taken to different transmission states. In a particular embodiment, the coating can provide a good balance between color difference and luminous transmission.
Material comprising a substrate provided with a stack of thin layers having thermal properties
A material includes a transparent substrate coated with a stack of thin layers successively including an alternation of three silver-based functional metal layers and of four dielectric coatings so that each functional metal layer is positioned between two dielectric coatings. Absorbent material is present between the first functional layer and the second functional layer, in a total thickness Abs2 such that 1.0≤Abs2≤5.0 nm and/or absorbent material is present between the second functional layer and the third functional layer, in a total thickness Abs3 such that 1.0≤Abs3≤5.0 nm. Additionally, absorbent material is present between the face of the substrate and the first functional layer in a total thickness such that 0.0<Abs1≤0.5 nm and absorbent material is present above the third functional layer, in a total thickness Abs4 such that 0.0<Abs4≤0.5 nm.
Transparent nanowire architectures for marine anti-fouling
A rational design and fabrication of ZnO/Al.sub.2O.sub.3 core-shell nanowire architectures with tunable geometries (length, spacing, branching) and surface chemistry is provided. The fabricated nanowires significantly delay or even prevent marine biofouling. In some embodiments, hydrophilic nanowires can reduce the fouling coverage by up to approximately 60% after 20 days compared to planar control surfaces. The mechanism of the fouling reduction is mainly due to two geometric effects: reduced effective settlement area and mechanical cell penetration. Further, superhydrophobic nanowires can completely prevent marine algal fouling for up to 22 days. Additionally, the developed nanowire surfaces are transparent across the visible spectrum, making them applicable to windows and oceanographic sensors.
Heating device equipped with a door comprising a triple glazing
A heating device equipped with a chamber defining a cavity, includes a door or wall incorporating a triple glazing including three transparent substrates defining, from the interior to the exterior of the cavity, faces numbered 1 to 6 respectively, at least the faces 1 and 2 of the first substrate and 3 and/or 4 of the second substrate being covered with heat-reflecting coatings, wherein the mean spacing e1 between the first substrate and the second substrate and the mean spacing e2 between the second substrate and the third substrate is different, the ratio between the largest spacing and the smallest spacing being greater than 1.1, and e1 and e2 being between 2 and 20 mm.
COATED ARTICLE WITH IR REFLECTING LAYER DESIGNED FOR LOW U-VALUE AND HIGHER G-VALUE AND METHOD OF MAKING SAME
A coated article incudes a low-emissivity (low-E) coating having at least one infrared (IR) reflecting layer of or including a material such as silver or the like. The low-E coating is designed so that the coated article can realize a low U-value in combination with a high solar heat gain (g value). In the top dielectric portion of the coating above the silver, a high-low-high refractive index sequence is provided. This allows for a low U-value and a higher g value to be obtained for a given silver thickness. Coated articles herein may be used in the context of insulating glass (IG) window units, or in other suitable applications such as monolithic window applications, laminated windows, and/or the like.
Low-E matchable coated articles having absorber film and corresponding methods
A low-E coating has good color stability (a low ΔE* value) upon heat treatment (HT). Thermal stability may be improved by the provision of an as-deposited crystalline or substantially crystalline layer of or including zinc oxide, doped with at least one dopant (e.g., Sn), immediately under an infrared (IR) reflecting layer of or including silver; and/or by the provision of at least one dielectric layer of or including an oxide of zirconium. These have the effect of significantly improving the coating's thermal stability (i.e., lowering the ΔE* value). An absorber film may be designed to adjust visible transmission and provide desirable coloration, while maintaining durability and/or thermal stability. The dielectric layer (e.g., of or including an oxide of Zr) may be sputter-deposited so as to have a monoclinic phase in order to improve thermal stability.

METHOD FOR PRODUCING A CURVED LAMINATED GLAZING
A method for producing a curved laminated glazing, for a windscreen or roof of a motor vehicle includes providing a first glass sheet, coated on at least one part of one of its faces with a stack of thin layers, depositing, on one part of the surface of the stack of thin layers in a zone to be cleared, a washable dissolving layer, a pre-firing after which the stack of thin layers located under the washable dissolving layer is dissolved by the washable dissolving layer, creating a cleared zone, the removal of the washable dissolving layer by washing, the deposit, at least on one part of the cleared zone, of an opaque mineral layer, the curving of the first glass sheet and of an additional glass sheet, together or separately, and the laminating of the first glass sheet with an additional glass sheet using a lamination interlayer.
