    • The invention generally relates to purification of carbon nanomaterials, particularly fullerenes, by removal of PAHs and other hydrocarbon impurities. The inventive process involves extracting a sample containing carbon nanomaterials with a solvent in which the PAHs are substantially soluble but in which the carbon nanomaterials are not substantially soluble. The sample can be repeatedly or continuously extracted with one or more solvents to remove a greater amount of impurities. Preferred solvents include ethanol, diethyl ether, and acetone. The invention also provides a process for efficiently separating solvent extractable fullerenes from samples containing fullerenes and PAHs wherein the sample is extracted with a solvent in which both fullerenes and PAHs are substantially soluble and the sample extract then undergoes selective extraction to remove PAHs. Suitable solvents in which both fullerenes and PAHs are soluble include o-xylene, toluene, and o-dichlorobenzene. The purification process is capable of treating quantities of combustion soot in excess of one kilogram and can produce fullerenes or fullerenic soot of suitable purity for many applications.

    • The present application describes methods for the testing of compounds of potential usefulness as therapeutic antioxidants and/or as therapeutic free radical scavengers. The animal model for testing such compounds is the Sod2CJE homozygous Manganese Superoxide Dismutase-deficient mouse. When pups of these mice are treated with certain antioxidants, they survive past about 7 days of age, and later develop characteristic histological changes and characteristic neurobehavioral disorders. Those treated mice can be further treated with test compounds which may or may not cross the blood brain barrier, and the life span and physical and neurobehavioral characteristics of those mice provide information about the potential utility of the test compound as a therapeutic antioxidant. Phenotypes of the treated mice allow conclusions regarding targeted areas of the brain and thus, applications to particular disorders such as Parkinsonism.
    • 本申请描述了测试作为治疗性抗氧化剂和/或作为治疗性自由基清除剂的潜在有用性的化合物的方法。 用于测试这些化合物的动物模型是Sod2CJE纯合的锰超氧化物歧化酶缺陷型小鼠。 当这些小鼠的幼仔用某些抗氧化剂处理时,它们可以在约7天龄之后存活,并且随后发展特征性组织学变化和特征性神经行为障碍。 那些治疗的小鼠可以进一步用可能或不可能穿过血脑屏障的测试化合物进行治疗,并且这些小鼠的寿命和物理和神经行为特征提供了关于测试化合物作为治疗性抗氧化剂的潜在效用的信息。 经处理的小鼠的表型允许关于脑的目标区域的结论,因此可以应用于特定疾病如帕金森综合征。

    • Filter devices and methods for collection of carbon nanomaterials, including fullerenes, produced in gas phase reactors are provided. The filter devices provide for in situ cleaning of filters to release captured product for collection. Product can be released and removed from the reactor without disrupting continuous synthesis of carbon nanomaterials. The filter devices facilitate increased reactor operation and larger scale production of carbon nanomaterials. The filters are cleaned by application of a motive force and/or a gas flow to the filter. In a specific embodiment filters are cleaned by a reverse flow of gas pulses to the filter provided. The invention also provides reactor systems for gas phase synthesis of carbon nanomaterials that can be operated continuously employing the filter device of this invention. Preferred reactor systems are those which synthesize carbon nanomaterials by combustion. Methods for continuous production of carbon nanomaterials using the filtering devices and methods of this invention are also provided.
