Abstract: It relates to a type of catalysts for preparation of chirality-selective and conductivity-selective single-walled carbon nanotubes. The catalysts have chemical compositions of ABy, wherein A is the metal tungsten (W), B stands for one or more metals selected from a group consisting of the transition metals manganese, iron, cobalt, copper, zinc, chromium, vanadium, rhodium, ruthenium, palladium, platinum, gold, silver, osmium, iridium, and the lanthanide rare earth metals, and y is in the range of 0.01-20.0. This catalyst can be used to catalyze the growth of single-walled carbon nanotubes with desired chirality and conductivity.

Abstract: This invention relates to the cleaning of flue gas released from various combustion processes, particularly a surface deposition NH3—SCR honeycomb catalyst and its preparation method. The catalyst is composed of framework material, TiO2, V2O5 and WO3, wherein the framework material is composed of clay, coal ash, mineral waste residue or their mixture. The mass fractions for framework material, TiO2, V2O5, and WO3 are 60 wt. % to 80 wt. %, 13 wt. % to 33 wt. %, 1 wt. % to 5 wt. %, and 0.1 wt. % to 2 wt. %, respectively. The nano V2O5—WO3—TiO2 particles were deposited on the surface of particle pore or honeycomb, and the performance of the catalyst could be greatly improved.

Abstract: Embodiments of the present invention provide a method and system for reducing congestion on a communication network. The communication network includes a network node having a first port and a second port. The network node is associated with forwarding data including first port forwarding data identifying at least one node accessible via the first port, and second port forwarding data identifying at least one node accessible via the second port. A failure associated with one of the first port and the second port is determined. The forwarding data corresponding to the other of the first port and the second port not associated with the failure, is updated with the one of the first port forwarding data and second port forwarding data corresponding to the one of the first port and the second port associated with the failure.
