    • Systems and methods for the formation of carbon-based nanostructures are generally described. In some embodiments, the nanostructures may be formed on a nanopositor. The nanopositor can comprise, in some embodiments, at least one of metal atoms in a non-zero oxidation state and metalloid atoms in a non-zero oxidation state. For example, the nanopositor may comprise a metal oxide, a metalloid oxide, a metal chalcogenide, a metalloid chalcogenide, and the like. The carbon-based nanostructures may be grown by exposing the nanopositor, in the presence or absence of a growth substrate, to a set of conditions selected to cause formation of carbon-based nanostructures on the nanopositor. In some embodiments, metal or metalloid atoms in a non-zero oxidation state are not reduced to a zero oxidation state during the formation of the carbon-based nanostructures. In some cases, metal or metalloid atoms in a non-zero oxidation state do not form a carbide during the formation of the carbon-based nanostructures.
    • 通常描述用于形成碳基纳米结构的系统和方法。 在一些实施方案中,纳米结构可以形成在纳米激光器上。 在一些实施方案中,纳米导体可以包括非零氧化态的金属原子和非零氧化态的准金属原子中的至少一种。 例如,纳米阳极剂可以包含金属氧化物,类金属氧化物,金属硫族化物,准金属硫族化物等。 碳纳米结构可以通过在存在或不存在生长衬底的情况下将纳米孔体暴露于所选择的一系列条件来生长,所述条件被选择用于在纳米反应器上形成碳基纳米结构。 在一些实施方案中,非零氧化态的金属或准金属原子在形成碳基纳米结构期间不会降低至零氧化态。 在一些情况下,非零氧化态的金属或准金属原子在形成碳基纳米结构期间不形成碳化物。

    • A rapid gelation, two-step method for the production of an aerogel precursor is disclosed. The method involves the addition of a small amount of catalyst during mixing of alcogel components in order to allow some pre-polymerization to occur. Next, the addition of the remainder of the catalyst quickly forms or gels the solution into the alcogel. The gelation of the solution to form the alcogel typically takes place in 5 to 60 seconds, but can be done in under 1 second and in as long as several hours. The gel time can be controlled specifically by adjusting the chemical contents of the solution and the amount of time between the two additions of catalyst. The resulting alcogel can then be processed further to form an aerogel which can be put to use in many unique applications including fabrics, insulative blocks, and microchips.
    • 公开了用于生产气凝胶前体的快速凝胶化,两步法。 该方法包括在混合醇醛组分期间加入少量催化剂以便使一些预聚合发生。 接下来,添加剩余的催化剂快速形成或凝胶溶液到凝胶中。 溶液形成胶凝胶的凝胶化通常在5至60秒钟内进行,但可以在1秒以下长达数小时内进行。 可以通过调节溶液的化学成分和两次添加催化剂之间的时间量来特异性地控制凝胶时间。 然后可以进一步处理所得的铝酸钙以形成气凝胶,其可以在许多独特的应用中使用,包括织物,绝缘块和微芯片。
