Abstract: A transparent article is described herein that includes: a substrate comprising an opposing first and second primary surface; and an optical film structure disposed on the first primary surface. The optical film structure comprises a scratch-resistant layer, a plurality of alternating high refractive index (RI) and low RI layers, and an outer and inner structure, the scratch-resistant layer disposed between the outer and inner structures. The outer structure can comprise at least one medium RI layer in contact with one of the high RI layers and the scratch-resistant layer. The medium RI layer comprises an RI from 1.55 to 1.80, each of the high RI layers comprises an RI of >1.80, and each of the low RI layers comprises an RI

Abstract: A glass-based assembly includes a glass substrate and a coating layer coupled to the glass substrate. Ultimate strength of the glass substrate with the coating layer overlaying and coupled thereto is greater than that of the glass substrate alone, without the coating layer.

Abstract: Frangible glass articles having a fracture behavior that resists ejection of glass particles upon fracture. In some embodiments, the frangible glass articles can have a first surface region with a first elastic compressive stress energy per unit area of glass (Welcomp1), a second surface region with a second elastic compressive stress energy per unit area of glass (Welcomp2), and a central region with an elastic tensile stress energy per unit area of glass (WT), where (Welcomp1+Welcomp2)−WT≤25 J/m2. In some embodiments, the frangible glass articles can have a total load ratio (Wi/GD) less than 6.5 and a total elastic compressive stress energy per unit area of glass (WC) less than 60% of a total load (Wi), where: WC=Welcomp1+Welcomp2, Wi=WC+WT, GD=4G1C, and

IPC: C03C17/34
Abstract: A glass-based assembly includes a glass or glass-ceramic substrate comprising a surface. The surface has flaws, such as a population of small cracks extending into the surface, whereby the substrate is weakened relative to ideal strength thereof. The assembly further includes a coating coupled to the substrate and overlaying at least some of the flaws. Ultimate strength of the substrate with the coating coupled thereto is greater than that of the substrate alone, without the coating.
