  • Patent number: 8445055
    Abstract: The invention relates to a method for the fabrication of composite palladium or palladium alloy membranes. The surface of the porous ceramic substrate is modified with pencil to create a uniform and smooth layer, and the membrane is deposited via electroless plating. The advantages of the pencil modification are a reduction of the substrate surface roughness and a repair of substrate surface defects, which leads to a great improvement in the membrane uniformity and hydrogen permeation performances. This method is facile and economic, and it is especially effective on low-cost macroporous ceramic substrate materials. Furthermore, this method generates almost no pollution and therefore is environmentally benign.

  • Patent number: 8189459
    Abstract: The invention discloses a method and system for guiding a packet data protocol activation. The method includes determining whether a packet data protocol is activated and if the determination result indicates that the packet data protocol is not activated because of including a wrong service access point name, analyzing service access point name information causing the packet data protocol not activated; introducing in an associating database for associating service access point name reason information causing the packet data protocol not activated and a guide information for properly setting the service access point name; inquiring the associating database based on the service access point name reason information obtained by the analyzing and obtaining the guide information for guiding a user to properly set the service access point name; and transmitting the guide information for guiding the user to properly set the service access point name to the user side.
