    摘要: In various embodiments, the present disclosure describes fullerene derivatives that are capable of photocatalytically generating reactive oxygen species in the presence of ultraviolet and/or visible light. In some embodiments, the fullerene derivatives are aminofullerenes containing a plurality of amine-terminated moieties covalently bonded to the fullerene cage. The fullerene derivatives may optionally be covalently bonded to a substrate surface for use in photocatalytic disinfection systems for removing various contaminants including, for example, bacteria, viruses, protozoa and chemical pollutants. Methods using the present fullerene and aminofullerene derivatives in various purification processes are also described herein.

    摘要: A method of producing nano-scaled graphene platelets with an average thickness smaller than 30 nm from a layered graphite material. The method comprises (a) forming a carboxylic acid-intercalated graphite compound by an electrochemical reaction; (b) exposing the intercalated graphite compound to a thermal shock to produce exfoliated graphite; and (c) subjecting the exfoliated graphite to a mechanical shearing treatment to produce the nano-scaled graphene platelets. Preferred carboxylic acids are formic acid and acetic acid. The exfoliation step in the instant invention does not involve the evolution of undesirable species, such as NOx and SOx, which are common by-products of exfoliating conventional sulfuric or nitric acid-intercalated graphite compounds. The nano-scaled platelets are candidate reinforcement fillers for polymer nanocomposites. Nano-scaled graphene platelets are much lower-cost alternatives to carbon nano-tubes or carbon nano-fibers.

    摘要: An apparatus for manufacturing a carbon nanostructure and a method for manufacturing a carbon nanostructure that can achieve an increase in length and shape stabilization of the carbon nanostructure can be obtained. A manufacturing apparatus for a carbon nanostructure includes a catalyst member on which a carbon nanostructure is grown, a source gas supply unit and a source gas supply pipe, a coil, and a heater. The source gas supply unit and the source gas supply pipe supply the catalyst member with carbon for forming the carbon nanotube. The coil applies a gradient magnetic field (e.g., a cusped magnetic field indicated by magnetic flux line whose magnetic field strength gradually increases from one surface of the catalyst member to the other surface opposite to the one surface. The heater heats the catalyst member.

    摘要: Carbon nanostructures are synthesized from carbon-excess explosives having a negative oxygen balance. A supercritical fluid provides an environment that safely dissolves and decomposes the explosive molecules into its reactant products including activated C or CO and provides the temperature and pressure for the required collision rate of activated C atoms and CO molecules to form carbon nanostructures such as graphene, fullerenes and nanotubes. The nanostructures may be synthesized without a metal reactant at relatively low temperatures in the supercritical fluid to provide a cost-effective path to bulk fabrication. These nanostructures may be synthesized “metal free”. As the supercritical fluid provides an inert buffer that does not react with the explosive, the fluid is preserved. Once the nanostructures are removed, the other reaction products may be removed and the fluid recycled.
