    摘要： The present invention is directed toward methods of attaching or grafting carbon nanotubes (CNTs) to silicon or other surfaces, wherein such attaching or grafting occurs via functional groups on either or both of the CNTs and silicon surface. The present invention is also directed to the novel compositions produced by such methods. Previous work by Applicants has demonstrated covalent attachment of arenes via aryldiazonium salts to Si (hydride passivated single crystal or poly Si; or , p-doped, n-doped or intrinsic), GaAs, and Pd surfaces. In the case of Si, this provides a direct arene-Si bond with no intervening oxide. Applicants have also reported on the use of aryldiazonium salts for the direct covalent linkage of arenes to single wall carbon nanotubes (SWNTs) where the nanotubes can exist either as bundles or individual structures (when surfactant-wrapped). In some embodiments, the present invention is directed to a merger of these two technologies to afford the covalent attachment of individualized (unroped) SWNTs to Si surfaces.

    摘要翻译： 本发明涉及将碳纳米管（CNT）附着或接枝到硅或其它表面上的方法，其中通过碳纳米管和硅表面之一或两者上的官能团进行这种附着或接枝。 本发明还涉及通过这些方法制备的新型组合物。 申请人的以前的工作已经证明了芳烃通过芳基重氮盐与Si（氢化物钝化单晶或多晶硅; <111>或<100>，p掺杂，n掺杂或本征），GaAs和Pd表面共价连接。 在Si的情况下，这提供了没有中间氧化物的直接芳烃-Si键。 申请人还报导了芳基重氮盐用于将芳烃直接共价连接到单壁碳纳米管（SWNT）上，其中纳米管可以以束或单独的结构（当表面活性剂包裹时）存在。 在一些实施方案中，本发明涉及这两种技术的合并，以提供个体化（未经处理的）SWNT共价连接到Si表面。

    摘要： A low-cost and facile method of purifying fullerenes to obtain a preparation enriched in a fullerene of selected molecular weight using activated carbon involves adding a fullerene mixture to the top end of a column comprising activated carbon, passing a solvent in which the selected molecular weight fullerene is soluble through the column, and recovering a fraction enriched in the selected molecular weight fullerene from the bottom end of the column. In addition to activated carbon, the column may further comprise silica gel, diatomaceous earth, or other materials which aid in column packing and eluent flow.

    摘要： In some embodiments, the present disclosure pertains to methods of capturing a gas from an environment by associating the environment (e.g., a pressurized environment) with a porous carbon material that comprises a plurality of pores and a plurality of nucleophilic moieties. In some embodiments, the associating results in sorption of gas components (e.g., CO2 or H2S) to the porous carbon materials. In some embodiments, the methods of the present disclosure also include a step of releasing captured gas components from porous carbon materials. In some embodiments, the releasing occurs without any heating steps by decreasing environmental pressure. In some embodiments, the methods of the present disclosure also include a step of disposing released gas components and reusing porous carbon materials. Additional embodiments of the present disclosure pertain to porous carbon materials that are used for gas capture.
