  • Publication number: 20130098840
    Abstract: Disclosed are nano-engineered porous ceramic composite filtration media for removal of phosphorous contaminates from wastewater and other water or liquid sources. Such porous ceramic media has high surface area and an interconnecting hierarchical pore structure containing nano-iron oxide/oxyhydroxide compounds, as well as other nano materials, surfactants, ligands or other compounds appropriate for removing higher amounts of phosphorous or phosphorous compounds. The composite media can be modified with nano-phased materials grown on the high surface area and addition of other compounds, contains hierarchical, interconnected porosity ranging from nanometer to millimeter in size that provides high permeability substrate especially suited for removal of contaminants at the interface of the water or other fluids and the nanomaterial or surfactants residing on the surfaces of the porous structure.

  • Patent number: 8409344
    Abstract: Cement compositions and methods for making cement compositions are provided. The cement compositions can comprise at least one oxide having a particle size of less than about 600 nm. The methods for making cement may include: providing a mixture of compounds containing the required calcium, silicon, aluminum, and iron to provide at least one of tricalcium silicate, dicalcium silicate, tricalcium aluminate, tetracalcium aluminoferrite, other calcium silicates, aluminates, ferrites, and silicates or combinations thereof; adding a fuel source and an oxidizer to the mixture of compounds; and heating the mixture of compounds, the fuel source, and the oxidizer such that the mixture of compounds, the fuel source, and the oxidizer ignite to form the at least one tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite, or combinations thereof.
