  • Photocatalyst having high visible-light activity
    Patent number: 10668458
    Abstract: A photocatalyst according to the present invention has a structure in which the titanium dioxide doped with the transition metals is supported on the support such that a band gap thereof is low and a specific surface area thereof is high, thereby exhibiting an excellent photocatalytic activity even in a visible light region and providing an excellent effect of adsorbing an organic compound and removing the same even under a condition in which light is not emitted.

  • Polymeric nanocomposites and methods for their preparation and use
    Patent number: 10227458
    Abstract: Methods of forming a polymeric nanocomposite are provided. The methods include combining one or more monomers to form a mixture and adding a plurality of carbon fibers to the mixture prior to or concurrently with formation of a polymer from the monomers. The methods can also include polymerizing the monomers to form the polymer and adding a hydrophobic agent and a plasticizer to the mixture to form the polymer nanocomposite.

  • Composite having metal hydroxide supported zeolite, and warm-mix asphalt additive containing the same
    Patent number: 10035135
    Abstract: The composite of the present invention includes zeolite having a metal hydroxide supported thereon, and thus it can release moisture inside the zeolite effectively. Therefore, the warm-mix asphalt additive including the composite is not only economical but also able to lower with ease the temperatures required for mixing and compacting an asphalt mixture. Also, the asphalt mixture including the above-described warm-mix additive has a benefit of an improved adhesive strength, which leads to an excellent resistance to plastic deformation.
