Abstract:
Capacitive devices are described having electrical interconnects (12) of electrodes (10) which possess efficient electrical contact between current collectors, electrical isolation (18) of electrodes, and/or electrochemical stability, while minimizing the mechanical stress and strain applied to the electrodes. The capacitive devices are adaptable to a wide range of electrode dimensions and electrode stack heights. This stack of planar electrodes could be used in double layer capacitor or in capacitive device for charge seperation of ions in solution.

Methods of making the composite carbon electrodes are also described. The composite carbon electrode comprises an electrically conductive porous matrix comprising carbon; and an electric double layer capacitor, comprising an activated carbonized material, dispersed throughout the pore volume of the electrically conductive porous matrix.

Abstract:
Methods of fabricating dimensional silica-based substrates or structures comprising a porous silicon layers are contemplated. According to one embodiment, oxygen is extracted from the atomic elemental composition of a silica glass substrate by reacting a metallic gas with the substrate in a heated inert atmosphere to form a metal-oxygen complex along a surface of the substrate. The metal-oxygen complex is removed from the surface of the silica glass substrate to yield a crystalline porous silicon surface portion and one or more additional layers are formed over the crystalline porous silicon surface portion of the silica glass substrate to yield a dimensional silica-based substrate or structure comprising the porous silicon layer. Embodiments are also contemplated where the substrate is glass-based, but is not necessarily a silica-based glass substrate. Additional embodiments are disclosed and claimed.

Abstract:
Packages for elements, e.g., OLEDs, that are temperature sensitive are provided. The packages have a first glass substrate (12), a second glass substrate (16), and a wall (14) that separates the first and second substrates (12, 16) and hermetically seals at least one temperature sensitive element (18, 28, 36) between the substrates (12, 16). The wall (14) comprises a sintered frit and at least a portion of the wall is laser sealed to the second substrate (16) by melting a glass component of the sintered frit. The minimum width (40) of the laser-sealed portion of the wall (14) at any location along the wall (14) is greater than or equal to 2 millimeters so as to provide greater hermeticity and strength to the package. The laser sealing is performed without substantially degrading the temperature sensitive element(s) (18, 28, 36) housed in the package.
Abstract:
An apparatus (10) and method for detecting defects in a transparent substrate (12) by simultaneously using a combination of bright field and dark field light sources for illuminating the substrate. The apparatus is capable of detecting both inclusions and surface defects simultaneously while the substrate is in motion, simplifying the characterization of substrates in a manufacturing setting.
