    摘要： Heterogeneous solid supra-molecular alkylalumoxanes. A supra-molecular architecture of a nano-particle foundation on which an alkylalumoxane is built. Supra-molecular alkylalumoxanes comprise (a) an aluminum-oxide nanoparticle, (b) a linkage unit, and (c) an alkylalumoxane. Supra-molecular alkylalumoxanes are prepared by the reaction of a chemically modified aluminum-oxygen nanoparticle with either a pre-formed alkylalumoxane or an alkylaluminum compound, with subsequent hydrolysis or reaction with other alkylalumoxane yielding reagents. The supra-molecular alkylalumoxanes are active as catalysts for the polymerization of organic monomers and as co-catalysts with transition metal components for the polymerization of olefins.

    摘要： Various embodiments of the present invention pertain to x-ray absorbing compositions that comprise a carbon material associated with an x-ray absorbing material. In some embodiments, the x-ray absorbing material is selected from the group consisting of lead-based compounds, bismuth-based compounds, and combinations thereof. In some embodiments, the carbon material is selected from the group consisting of carbon nanotubes, graphenes, carbon fibers, amorphous carbons, and combinations thereof. In further embodiments, the carbon materials of the present invention may also be treated with a surfactant, an acid, polymers or combinations thereof. In some embodiments, the carbon materials of the present invention may be further associated with a metal oxide. Additional embodiments of the present invention pertain to methods of making the aforementioned x-ray absorbing compositions. Such methods generally include associating a carbon material with an x-ray absorbing material.
