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.

The present disclosure includes carbon-carbon composite articles having oxidation protection coatings for limiting thermal and catalytic oxidation reactions and methods for applying oxidation protection coatings to carbon-carbon composite articles.

A lithium-ion conductive glass-ceramic article has a crystalline component characterized by the formula MA.sub.2(XO.sub.4).sub.3, where M represents one or more monovalent or divalent cations selected from Li, Na and Zn, A represents one or more trivalent, tetravalent or pentavalent cations selected from Al, Cr, Fe, Ga, Si, Ti, Ge, V and Nb, and X represents P cations which may be partially substituted by B cations.

Fiber-reinforced separators/solid electrolytes suitable for use in a cell employing an anode comprising an alkali metal are disclosed. Such fiber-reinforced separators/solid electrolytes may be at least partially amorphous and prepared by compacting, at elevated temperatures, powders of an ion-conducting composition appropriate to the anode alkali metal. The separators/solid electrolytes may employ discrete high aspect ratio fibers and fiber mats or plate-like mineral particles to reinforce the separator solid electrolyte. The reinforcing fibers may be inorganic, such as silica-based glass, or organic, such as a thermoplastic. In the case of thermoplastic fiber-reinforced separators/solid electrolytes, any of a wide range of thermoplastic compositions may be selected provided the glass transition temperature of the polymer reinforcement composition is selected to be higher than the glass transition temperature of the amorphous portion of the separator/solid electrolyte.

The present invention concerns a method for polishing a phosphate glass or fluorophosphate glass substrate comprising polishing the surface of said substrate using at least a formulation having a pH comprised between 7 and 14 comprising at least a cerium containing abrasive, an anionic water-soluble polymer dispersant, an anti-caking agent, optionally a co-dispersant and water.

A polyphosphate-based glass scale inhibition composition comprising from about 45 to about 55 mole percent P.sub.2O.sub.5, from about 35 to about 45 mole percent of an oxide of an alkaline earth metal, and from about 8 to about 12 mole percent of an oxide of an alkali metal.
