The present invention relates to a process for manufacturing glass sheets with diffuse finish and the resulting glass sheet by this process. The glass sheet is subjected to a series of alternate immersions in acidic solutions and alkaline solutions to remove impurities and waste and to generate a diffuse finish on both sides of the glass sheet. The process generates in the glass sheet in at least one side, a diffuse surface with a peak to valley roughness (Rt) of between 5.8343 μm and 9.3790 μm; an average roughness (Ra) value between 0.8020 μm and 0.9538 μm; an RMS roughness between 0.9653 μm and 1.1917 μm; a solar transmission between 84.8% and 46.50%; a solar reflection between 7.4 and 4.4%; a light transmission between 88.5% and 67.70%; a reflection of light between 6.50% and 5.20%; and UV transmission between 35.60% and 70.20%.

In a method for removing an organic adhesive from a glass carrier in a semiconductor manufacturing process, the glass carrier is placed into a process chamber. The glass carrier is rotated and heated sulfuric acid is applied or sprayed onto the glass carrier. Ozone is introduced into the process chamber. The ozone diffuses through the sulfuric acid to the organic adhesive on the surface of the glass carrier. The sulfuric acid and the ozone chemically react with the organic adhesive and remove it from the glass carrier.

Provided is a glass film in which an optical defect is less likely to occur and which has excellent handleability. The glass film has a thickness of 150 μm or less and has flexibility. On one surface of the glass film, the number of deposited contaminants of 5 μm or more is 130/m.sup.2 or more, and the number of deposited contaminants of 100 μm or more is 10/m.sup.2 or less. On one surface of the glass film, the number of deposited contaminants of 5 μm or more and less than 100 μm is preferably 130 to 1200/m.sup.2. The glass film preferably has a length of 100 m or more.

Embodiments of the present disclosure provides a housing assembly, a preparation method therefor and an electronic device. The housing assembly includes: a transparent substrate, including a decorative surface; wherein the decorative surface is arranged with a rough area; and a reflective layer, arranged on the decorative surface and at least partially covering the rough area.

A method of making a glass article, for example a glass light guide plate comprising at least one structured surface including a plurality of channels and peaks. The glass article may be suitable for enabling one dimensional dimming when used in a backlight unit for use as an illuminator for liquid crystal display devices.

According to one embodiment, a method for producing a coated glass article may include applying an anti-reflective coating onto a glass substrate. The glass substrate may include a first major surface, and a second major surface opposite the first major surface. The anti-reflective coating may be applied to the first major surface of the glass substrate. A substrate thickness may be measured between the first major surface and the second major surface. The glass substrate may have an aspect ratio of at least about 100:1. The coated glass article may have a reflectance of less than 2% for all wavelengths from 450 nanometers to 700 nanometers. The anti-reflective coating may include one or more layers. The cumulative layer stress of the anti-reflective coating may have an absolute value less than or equal to about 167,000 MPa nm.

The present disclosure relates to a glass cleaning agent, a self-cleaning glass, and preparation methods thereof. The cleaning agent for a glass includes, by weight percentage, 40% to 65% of silicone monomer, 10% to 20% of a first silane coupling agent, 5% to 15% of a second silane coupling agent, 0.1% to 2% of organic tin catalyst, and 5% to 20% of crosslinking agent. The first silane coupling agent is at least one selected from the group consisting of γ-aminopropyltriethoxysilane and N-(β-aminoethyl)-γ-aminopropyltrimethoxysilane. The second silane coupling agent is γ-glycidoxypropyltrimethoxysilane.

A method is provided to form a dust mitigation coating that also mitigates or repels water, ice, and other liquids. Techniques to coat the surfaces of equipment and items with these dust, liquid, and ice mitigation coatings, minimize or eliminate mission problems caused by dust, liquid, or ice accumulation, particularly in outer space or on another planetary body or moon. Further, the dust mitigation coatings exhibit a Lotus-like effect, making the coated surfaces ultra-hydrophobic. The present invention is also directed to techniques for improving the functioning of terrestrial-based equipment and systems where dust, liquid, or ice accumulation is a problem, such as in hospitals and other health contexts, to prevent contamination.
