  • Publication number: 20120165558
    Abstract: The present invention relates to microporous molecular sieve materials and their analogue molecular sieve materials having a crystalline unilamellar or multilamellar framework with a single unit cell thickness in which layers are aligned regularly or randomly, the molecular sieve materials being synthesized by adding an organic surfactant to the synthesis composition of zeolite. In addition, the present invention relates to micro-mesoporous molecular sieve materials activated or functionalized by dealumination, ion exchange or other post treatments, and the use thereof as catalyst. These novel materials have dramatically increased external surface area by virtue of their framework with nano-scale thickness, and thus exhibit improved molecular diffusion, and thus have much higher activities as catalyst and ion exchange resin than conventional zeolites.

  • Patent number: 8194624
    Abstract: A method of resource allocation among mobile stations in distributed communication network enables a mobile station to perceive existence of another mobile station through a time slot for resource allocation without having to communicate with a sensor node. If perceiving another mobile station, the mobile station allocates time slot resources not to overlap with the time slot resources of another mobile station, and performs location measurement or media access and reception of service from the sensor node through the allocated time slot resources. Because the mobile stations of the network can perceive each other by communicating with each other, and accordingly allocate their own resources without overlapping with the resource of the others, frequent collision of the signal for location measurement can be prevented.
