Embodiments of the disclosure relate to a rollable glass sheet configured to reversibly transition between a flat configuration and a bent configuration.

At a radius of curvature of 50 mm, the first major surface includes a second surface compressive stress less than the first compressive stress and a second depth of compression less than the first depth of compression and greater than 11 μm.

Embodiments of thermally and chemically strengthened glass-based articles are disclosed. In one or more embodiments, the glass-based articles may include a first surface and a second surface opposing the first surface defining a thickness (t), a first CS region comprising a concentration of a metal oxide that is both non-zero and varies along a portion of the thickness, and a second CS region being substantially free of the metal oxide of the first CS region, the second CS region extending from the first surface to a depth of compression of about 0.17•t or greater. In one or more embodiments, the first surface is flat to 100 μm total indicator run-out (TIR) along any 50 mm or less profile of the first surface. Methods of strengthening glass sheets are also disclosed, along with consumer electronic products, laminates and vehicles including the same are also disclosed.

Pastes are disclosed that are configured to coat a passage of a substrate. When the paste is sintered, the paste becomes electrically conductive so as to transmit electrical signals from a first end of the passage to a second end of the passage that is opposite the first end of the passage. The metallized paste contains a lead-free glass frit, and has a coefficient of thermal expansion sufficiently matched to the substrate so as to avoid cracking of the sintered paste, the substrate, or both, during sintering.

A glass, glass-ceramic, or ceramic bead is described, with an internal porous scaffold microstructure that is surrounded by an amorphous shield. The shield serves to protect the internal porous microstructure of the shield while increasing the overall strength of the porous microstructure and improve the flowability of the beads either by themselves or in devices such as biologically degradable putty that would be used in bone or soft tissue augmentation or regeneration. The open porosity present inside the bead will allow for enhanced degradability in-vivo as compared to solid particles or spheres and also promote the growth of tissues including but not limited to all types of bone, soft tissue, blood vessels, and nerves.
