  • Patent number: 9017773
    Abstract: A method is described for depositing nanostructures, such as nanostructures of conducting polymers, carbon nanostructures, or combinations thereof. The process comprises placing the nanostructures in a liquid composition comprising an immiscible combination of aqueous phase and an organic phase. The mixture is mixed for a period of time sufficient to form an emulsion and then allowed to stand undisturbed so that the phases are allowed to separate. As a result the nanostructure materials locate at the interface of the forming phases and are uniformly dispersed along that interface. A film of the nanostructure materials will then form on a substrate intersecting the interface, said substrate having been placed in the mixture before the phases are allowed to settle and separate.

  • Patent number: 9000660
    Abstract: Hydro-carbon nanorings may be used, e.g., in power storage power transmission and transportation. Sufficiently cooled, an externally hydrogen doped carbon nanoring may be used to create a radial dipole containment field for electrons rotating in the nanoring. Such nanorings may transmit DC current with little or no loss. Similarly, an internally hydrogen doped carbon nanoring may be used to create a radial dipole containment field for positrons rotating in the nanoring. Virtually lossless transmission of AC current may be achieved by pairing such streams of electrons and positrons in their respective containment fields. Closed rotation of such streams may also be used to efficiently store large amounts of electrical energy. Finally, by selectively accelerating and decelerating pairs of such paired electron and positron streams, which are moving at relativistic speeds, differential momentum may be created to cause physical movement.

  • Publication number: 20140355930
    Abstract: An all-dielectric metamaterial cladding is provided that can strongly confine light inside conventional low-index dielectric waveguides for use with photonic integrated circuits and nano-photonic devices. A class of metamaterials with dual electric and magnetic anisotropy along with giant birefringence can provide the ideal quasi-transverse electromagnetic mode propagation inside a glass core. A Transformed Cladding Waveguide can show an order of magnitude decreased cross-talk as compared to conventional waveguides.

  • Patent number: 8883903
    Abstract: Preparation of semiconductor nanocrystals and their dispersions in solvents and other media is described. The nanocrystals described herein have small (1-10 nm) particle size with minimal aggregation and can be synthesized with high yield. The capping agents on the as-synthesized nanocrystals as well as nanocrystals which have undergone cap exchange reactions result in the formation of stable suspensions in polar and nonpolar solvents which may then result in the formation of high quality nanocomposite films.
