Abstract:
A substrate with a textured surface is disclosed. The substrate may be, for example, a light emitter comprising a light guide, for example a backlight element for use in a display device, wherein a surface of the light guide, for example a glass substrate, is configured to have a textured surface with a predetermined RMS roughness and a predetermined correlation length of the texture. A plurality of light scatter supressing features can be provided on the textured surface. Textured surfaces disclosed herein may be effective to reduce electrostatic charging of the substrate surface. Methods of producing the textured surface are also disclosed.
Abstract:
Delamination resistant glass containers with heat-tolerant coatings are disclosed. In one embodiment, a glass container may include a glass body having an interior surface, an exterior surface and a wall thickness extending from the exterior surface to the interior surface. At least the interior surface of the glass body is delamination resistant. The glass container may further include a heat-tolerant coating positioned on at least a portion of the exterior surface of the glass body. The heat-tolerant coating may be thermally stable at temperatures greater than or equal to 260° C. for 30 minutes.
Abstract:
Disclosed herein are delamination resistant glass pharmaceutical containers which may include a glass body having a Class HGA1 hydrolytic resistance when tested according to the ISO 720:1985 testing standard.

Abstract:
Fusion-formable sodium-containing aluminosilicate and boroaluminosilicate glasses are described. The glasses are particularly useful for controlled release of sodium—useful in semiconductor applications, such as thin film photovoltaics where the sodium required to optimize cell efficiency is to be derived from the substrate glass.
