Abstract: A glass substrate with modified surface regions is disclosed. The glass substrate includes a first side and an opposite second side, an alkali-containing bulk disposed between the first and second sides, and a first alkali-depleted region formed in the alkali-containing bulk on the first side. The first alkali-depleted region defines at least a portion of a first topographical feature. The first topographic feature includes a height that extends in a first direction from a base portion of the first topographical feature to an outermost portion of the first topographical feature. The first direction is oriented parallel to a thickness of the glass substrate between the first and second sides. The first topographic feature also includes a width that extends in a second direction between at least two, spaced apart wall portions of the first topographical feature. The second direction is oriented normal to the first direction.

Abstract: Techniques for screening homopolymers, copolymers or blends for fabrication are disclosed. A data repository stores data points. Each data point comprises a structural repeating unit (SRU) and at least one material property value for the SRU. Each SRU is a homopolymer SRU, a copolymer component SRU or a blend component SRU. A machine determines a fingerprint for at least a subset of the SRUs in the data repository. The machine stores, in the data repository, each determined fingerprint in conjunction with a corresponding SRU. The machine generates a quantitative modeling engine to predict material property values, based on SRUs, for homopolymers, copolymers or blends. The quantitative modeling engine is based, at least in part, on the fingerprints. The machine identifies, using the quantitative modeling engine, at least one homopolymer SRU, copolymer SRU set or blend SRU set that has a material property value within a given range.

Abstract: A glass substrate with modified surface regions is disclosed. The glass substrate includes an alkali-containing bulk, a first alkali-depleted region, a second alkali-depleted region, and a first ion-exchanged region. The alkali-containing bulk has a first surface and a second surface with the first and second surfaces on opposite sides. The first alkali-depleted region extends into the alkali-containing bulk from the first surface. The second alkali-depleted region extends into the alkali-containing bulk from the second surface. The first ion-exchanged region extends into the alkali-containing bulk from the first surface. The first alkali-depleted region, the second alkali-depleted region, and the first ion-exchanged region each have a substantially homogenous composition. A method of forming the glass substrate is disclosed. The method includes simultaneously forming the first alkali-depleted region and the first ion-exchanged region in the first surface. The method also includes near-simultaneously forming the second alkali-depleted region in the second surface.

Abstract: A glass substrate according to one or more embodiments is disclosed. The glass substrate includes an alkali-containing bulk, at least one first alkali-depleted region, and at least one second alkali-depleted region. The alkali-containing bulk has a first surface and a second surfaces with the first and second surfaces opposing one another. The at least one first alkali-depleted region extends into the alkali-containing bulk from the first surface. The at least one second alkali-depleted region extends into the alkali-containing bulk from the second surface. The first alkali-depleted region and the second alkali-depleted region are amorphous and have a substantially homogenous composition. The first alkali-depleted region in some embodiments is a first alkali-depleted surface layer that extends across the alkali-containing bulk. The first alkali-depleted region in some embodiments is plurality of first alkali-depleted regions that are spaced apart from one another.
