  • Patent number: 7740821
    Abstract: A mesoporous silicate is prepared by a method that includes combining a silicate precursor, a bifunctional catalyst, and a structure-directing surfactant in an aqueous medium having a pH of about 4 to about 10. A mesoporous silicate forms as an aqueous suspension and can then be isolated. The mesoporous silicate can be formed under mild conditions of temperature and pH, and it exhibits a surprisingly high degree of network condensation.

  • Patent number: 7527826
    Abstract: Methods and resulting structures are described in which a metal layer is adhered to a surface of a substrate. The methods involve applying a sacrificial acidic organic layer to the surface of the substrate prior to depositing the metal layer onto the substrate. During deposition of the metal layer, the sacrificial acidic organic layer is substantially consumed, thereby leaving behind a metal/substrate interface that has excellent adhesion properties.
