  • Systems and Methods Employing Carbon Dots for the Measurement of Per- And Poly-Fluoroalkyl Substances
    Publication number: 20230393068
    Abstract: Disclosed herein are carbon dots and methods for capturing and detecting per- and/or polyfluoroalkyl substances (“PFASs”) in a liquid sample. One or more PFASs are integrated in the carbon dots and are capable of binding to certain PFASs in the sample. By comparing spectral parameters of the resulting carbon dots with a reference, the identity of the PFAS can be determined.

  • LOW THERMAL CONDUCTIVITY CARBON-CONTAINING MATERIALS AND METHODS OF PRODUCING THE SAME
    Publication number: 20190257005
    Abstract: The presently disclosed subject matter relates generally to low thermal conductivity carbon materials and methods of producing the same. In some embodiments, the carbon materials are doped with low thermally conductive nanoparticles. In some embodiments, carbon fibers are prepared by electrospinning a mixture of polymers; and/or incorporating a low thermal conductivity additive, such as nanoparticles.
