  • Patent number: 8535423
    Abstract: Methods of purifying hydrogen-containing materials are described. The methods may include the steps of providing a purifier material comprising silica. The silica may be heated at temperature of about 100° C. or more in a dry atmosphere to form activated silica. The activated silica may be contacted with a starting hydrogen-containing material, where the activated silica reduces a concentration of one or more impurity from the starting hydrogen-containing material to form the purified hydrogen-containing material, and where the activated silica does not decompose the purified hydrogen-containing material.

  • Patent number: 7947111
    Abstract: Novel uses and methods of use for inorganic and macroreticulate polymer bonding to metals to control moisture and oxygen in OLED, and other like devices, are provided. Materials having color change capacity are also provided for the removal of moisture from an OLED, where the material changes color upon reaching its capacity and thereby signals the user that the OLED is no longer protected from moisture damage.

  • Patent number: 7033418
    Abstract: A process for removing trace amounts of moisture and/or one or more impurities from contaminated hydride, inert and non-reactive gases, thus decreasing the concentration of the impurities to parts-per-billion (ppb) or parts-per-trillion (ppt) levels. The gas purifier materials of this invention include thermally activated aluminas, said aluminas including organic alumina materials, modified organic alumina materials, and modified inorganic aluminas. The thermally activated alumina materials of this invention are activated by heating the alumina material at a temperature between about 50° C.–1000° C. in an inert or non-inert atmosphere or in a vacuum and maintaining the activated material in the inert or non-inert atmosphere or in a vacuum atmosphere subsequent to said activation but prior to use.
