A glass article includes a first surface; a second surface opposed to the first surface; a side surface connecting the first surface to the second surface; a first surface compressive region extending from the first surface to a first depth; a second surface compressive region extending from the second surface to a second depth; and a side compressive region extending from the side surface to a third depth, where the first surface and the side surface are non-tin surfaces, the second surface is a tin surface, and a maximum compressive stress of the second surface compressive region is greater than a maximum compressive stress of the first surface compressive region.

A method includes heating a glass preform having a plurality of glass layers and drawing the glass preform in a distal direction to form a drawn glass sheet extending distally from the glass preform and having the plurality of glass layers. The drawn glass sheet is thinner than the glass preform. The drawn glass sheet can be rolled onto a collection spool. At least a portion of a glass layer can be removed from the drawn glass sheet. An exemplary glass sheet includes a first glass layer, a second glass layer adjacent to the first glass layer, and a thickness of at most about 0.1 mm. An exemplary ion exchanged glass sheet includes a thickness of at most about 0.1 mm and a surface layer that is under a compressive stress and extends into an interior of the glass sheet to a depth of layer.

When on flat glass elements an anti-corrosion agent and a separation agent, containing a powdery anti-corrosion agent and a powdery separation agent, is applied with the anti-corrosion agent and the separation agent being jointly applied on at least one side of the flat glass elements, the partial quantities of the powdery separation agent and the powdery anti-corrosion agent can be dosed according to requirement without causing an excess of separation agent or a shortage of anti-corrosion agent by holding ready and dosing the said anti-corrosion agent and separation agent independently from each other and by blending them together only after dosing.

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.

A temporary protective coating for heat treatable coated glass article includes acrylic monomers or solid particle reinforced acrylic monomers is disclosed. The temporary protective coating of the present disclosure is completely devoid of oligomeric acrylates. The temporary protective coating is applied directly over a functionally coated transparent substrate to protect the coated substrate during heat treatment and handling of the coated substrate before heat treatment. The temporary protective coating is completely removed during the heat treatment leaving behind no residues thereby keeping the physical properties of the functionally coated substrate intact.

An article includes a substrate including two main faces defining two main surfaces separated by edges, the substrate bearing a functional coating deposited by magnetron sputtering deposited on at least one portion of one main surface, and a temporary protective layer deposited on at least one portion of the functional coating, wherein, the temporary protective layer is deposited directly in contact with the functional coating, the temporary protective layer has a thickness of at least 1 micrometer, the temporary protective layer is not soluble in water, and the temporary protective layer is obtained from a composition comprising (meth)acrylate compounds, the substrate bearing the functional coating has not undergone a heat treatment at a temperature above 400° C.

Methods for protecting transparent electronically conductive layers on glass substrates are described herein. Methods include depositing a sacrificial coating during deposition of the transparent electronically conductive layer, before packing the glass substrate for storage or shipping, after unpacking glass substrates from a stack of glass substrates, and/or after a washing operation prior to fabricating an electrochromic stack on the transparent electronically conductive layer. Methods also include removing the sacrificial coating during a washing operation, during tempering, or prior to depositing an electrochromic stack by, e.g., heating the sacrificial coating or exposing the sacrificial coating to an inert plasma.

The disclosure discloses a high-flux and ultra-sensitive detection dot array enhancement chip, and belongs to the field of food safety detection. In the disclosure, single-layer Au nano-particles are chemically bonded onto a hydrophilic substrate, an Au nano-material is naturally deposited in holes of the chip under an electrostatic adsorption action, and a regular dot array is formed. Au particles distributed in the holes are separated with a particle surfactant (CTAB) to form plasma gaps so as to enhance the self-assemble of Au nano-particles distributed on hot-spots for a long range effect, thereby improving the sensing signal in detection efficiency and sensitivity of the chip.
