  • Patent number: 9005552
    Abstract: Provided is a new catalyst capable of removing carbon monoxide economically without adding particular reaction gas externally. Also provided are a process for producing and an apparatus using such a catalyst. Impregnation of a Ni—Al composite oxide precursor of a nonstoichiometric composition prepared by the solution-spray plasma technique with a ruthenium salt to be supported and performing reduction treatment allows CO methanation reaction to selectively proceed even in the high-temperature range in which CO2 methanation reaction and reverse water-gas-shift reaction proceed preferentially with conventional catalysts. Selective CO methanation reaction occurs reproducibly with another Ni—Al composite oxide precursor or an additive metallic species.

  • Patent number: 8992696
    Abstract: A method of bonding a metal to a substrate involves forming a plurality of nano-features in a surface of the substrate, where each nano-feature is chosen from a nano-pore and/or a nano-crevice. In a molten state, the metal is over-cast onto the substrate surface, and penetrates the nano-features. Upon cooling, the metal is solidified inside the nano-features, where the solidification of the metal forms a mechanical interlock between the over-cast metal and the substrate.

  • Publication number: 20150050740
    Abstract: The present invention discloses a method for introducing an exogenous DNA by overcoming the restriction modification barrier of the target bacterium. The method provided in the present invention comprises the steps of 1) co-expressing all DNA-methyltransferase-encoding genes in the genome of the target bacterium in E. coli in which the restriction modification system thereof has been deleted to obtain a recombinant bacterium A; 2) introducing an exogenous DNA molecule into the recombinant bacterium A for in vivo modification so as to obtain a methylation-modified exogenous DNA molecule; 3) introducing the methylation-modified exogenous DNA molecule into the target bacterium. The experiments of the invention have demonstrated that the invention has a high transformation efficiency compared to prior methods for enabling genetic manipulation by overcoming the restriction modification barrier of the bacterium.
