Disclosed herein are sealed devices comprising a first substrate, a second substrate, an inorganic film between the first and second substrates, and at least one weld region comprising a bond between the first and second substrates. The weld region can comprise a chemical composition different from that of the inorganic film and the first or second substrates. The sealed devices may further comprise a stress region encompassing at least the weld region, in which a portion of the device is under a greater stress than the remaining portion of the device. Also disclosed herein are display and electronic components comprising such sealed devices.

A standalone lithium ion-conductive sulfide solid electrolyte can include a freestanding inorganic vitreous sheet of sulfide-based lithium ion conducting glass capable of high performance in a lithium metal battery by providing a high degree of lithium-ion conductivity while being highly resistant to the initiation and/or propagation of lithium dendrites. Such an electrolyte is also itself manufacturable, and readily adaptable for battery cell and cell component manufacture, in a cost-effective, scalable manner. Methods of making and using the electrolyte, and battery cells and cell components incorporating the electrolyte are also disclosed.

A spacer is interposed between a pair of glass substrates facing each other. The spacer is disposed in contact with the pair of glass substrates. The spacer includes a center portion having a plate shape or a columnar shape, and both end portions protruding from both end surfaces of the center portion. At least any one of the both end portions has a spherical cap shape, or a spherical zone shape or a truncated conical shape. A radius A of a base portion at each of the both end portions is equal to a radius B of the center portion, or is smaller than the radius B.

The present disclosure provides glass compositions that include from about 20 mol % to 45 mol % of B.sub.2O.sub.3; and from about 10 mol % to about 80 mol % of one or more glass components selected from the group consisting of CaO and MgO. The glass compositions also include less than 0.1 mol % CdO. The glass compositions may include one or more of Na.sub.2O, K.sub.2O, and a phosphate source, where the B2O3 and the phosphate source total about 60 mol % or less. The glass compositions may include a source of fluoride. The glass composition may be used to desensitize dentin. The present disclosure also provides dentin-desensitizing compositions, as well as methods and uses of the disclosed glass compositions.
