  • Publication number: 20240122037
    Abstract: A display device includes a substrate that includes a display area and a non-display area, a display element layer disposed on the display area of the substrate, an opposing substrate that faces the substrate and the display element layer, a sealing member disposed on the non-display area and that couples the substrate and the opposing substrate, and a filler disposed between the substrate and the opposing substrate. A thickness of the filler varies in the range of 60% to 400% of a thickness of the sealing member.

  • Publication number: 20040050795
    Abstract: To more effectively remove contaminants from fluid streams, several types of metal precursors can be incorporated onto highly ordered mesoporous molecular sieves, such as SBA-15, without producing of clogging effects within pore structures. Lanthanum and aluminum are the most favorable incorporated metals in terms of their adsorption capacities and fluid velocities. The lanthanum impregnated SBA-15 also has a very strong selectivity for arsenic because its adsorption capacities do not deteriorate even if several other anionic species, such as sulfate and nitrate, are found in high concentrations in the fluid along with any arsenic. As a result, these hybrid materials have many advantages for use in POE/POU applications, among others, due to its rapid and high adsorption capacity, and its high selectivity of arsenic for removal from the fluid stream.

  • Publication number: 20030177799
    Abstract: A method for utilizing waste rubber materials for construction of turf areas such as golf courses or athletic fields is disclosed. The method involves implementing waste rubber materials as a drainage layer to provide the following benefits: capability of adsorbing contaminants, insulation, and a lightweight construction backfill material. Also, the method involves the use of waste rubber materials as a supporting layer for athletic fields for the resiliency and shock absorption. Secondly, a method for utilizing waste rubber materials for filtration of runoff from turf or vegetated areas is disclosed. The method involves implementing waste rubber materials as a filter medium for adsorption of contaminants from runoff before entering detention ponds, wetlands, or other water bodies.
