摘要： Compositions containing a transporter component and a signaling component and a method for using said compositions for analyzing porous media and flowing liquid streams, specifically for measuring pressure, temperature, relative abundance of water, pH, redox potential and electrolyte concentration. Analytes may include petroleum or other hydrophobic media, sulfur-containing compounds. The transporter component includes an amphiphilic nanomatenal and a plurality of solubilizing groups covalently bonded to the transporter component. The signaling component includes a plurality of reporter molecules associated with the transporter component. Said reporter molecules may be releasable from the transporter component upon exposure to at least one analyte. The reporter molecules may be non-covalently associated with the transporter component, or the reporter molecules are covalently bonded to the transporter component. Furthermore, said compositions and methods may be used to actively enhance oil recovery and for remediation of pollutants.

摘要： In various embodiments, the present disclosure describes processes for preparing functionalized graphene nanoribbons from carbon nanotubes. In general, the processes include exposing a plurality of carbon nanotubes to an alkali metal source in the absence of a solvent and thereafter adding an electrophile to form functionalized graphene nanoribbons. Exposing the carbon nanotubes to an alkali metal source in the absence of a solvent, generally while being heated, results in opening of the carbon nanotubes substantially parallel to their longitudinal axis, which may occur in a spiralwise manner in an embodiment. The graphene nanoribbons of the present disclosure are functionalized on at least their edges and are substantially defect free. As a result, the functionalized graphene nanoribbons described herein display a very high electrical conductivity that is comparable to that of mechanically exfoliated graphene.

摘要翻译： 在各种实施方案中，本公开描述了从碳纳米管制备官能化石墨烯纳米带的方法。 通常，该方法包括在不存在溶剂的情况下将多个碳纳米管暴露于碱金属源，然后加入亲电体以形成官能化的石墨烯纳米带。 通常在加热的情况下，将碳纳米管暴露于碱金属源，通常在被加热的情况下导致碳纳米管的开口基本上平行于它们的纵向轴线，这在实施例中可以以螺旋方式发生。 本公开的石墨烯纳米带至少在其边缘上被官能化，并且基本上是无缺陷的。 因此，本文所述的功能化石墨烯纳米带显示出与机械剥离的石墨烯相当的非常高的电导率。
