    • Full-duplex Wireless with Large Antenna Arrays 

      Everett, Evan Jackson (2015-12-03)
      To meet the growing demand for wireless data, base stations with very large antenna arrays are being deployed in order to serve multiple users simultaneously. Concurrently, there is growing interest in full-duplex operation. ...
    • Full-duplex Wireless: Design, Implementation and Characterization 

      Duarte, Melissa (2012)
      One of the fundamental assumptions made in the design of wireless networks is that the wireless devices have to be half-duplex, i.e., they cannot simultaneously transmit and receive in the same frequency band. The key ...
    • Fullerene (C60)-based X-ray contrast agent for diagnostic imaging 

      Wilson, Lon J.; Wharton, John T.; Sagman, Uri (2003-12-09)
      An contrast agent for therapeutic or diagnostic treatment comprises a fullerene scaffold and an iodinated moiety bonded to the scaffold. The agent may further comprise a water solubilizing moiety bonded to the scaffold, ...
    • Fullerene compositions and methods for photochemical purification 

      Alvarez, Pedro J. J.; Lee, Jaesang; Wilson, Lon J.; Mackeyev, Yuri; Kim, Jaehong (2014-03-25)
      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, ...
    • Fullerene contrast agent for magnetic resonance imaging and spectroscopy 

      Alford, John M.; Wilson, Lon J. (2002-03-12)
      A non-toxic contrast agent for enhancing contrast in in vivo magnetic resonance measurements, comprised of a water-soluble, stable paramagnetic fullerene that is free of paramagnetic metal species. A preferred contrast ...
    • Fullerene hydrides and studies toward the syntheses of fulvalenes 

      Peera, Asghar A. (2005)
      Benkeser reduction was used to synthesize highly hydrogenated fullerenes, C60H36, C60H38, C 60H40, C60H42 and C60H 44. 1H- and 13C-NMR spectra of HPLC purified fractions show that more highly hydrogenated fullerenes exhibit ...
    • Fullerene nanotube compositions 

      Smalley, Richard E.; Colbert, Daniel T.; Dai, Hongjie; Liu, Jie; Rinzler, Andrew G.; Hafner, Jason H.; Smith, Kenneth A.; Guo, Ting; Nikolaev, Pavel; Thess, Andreas (2008-06-24)
      This invention relates generally to a fullerene nanotube composition. The fullerene nanotubes may be in the form of a felt, such as a bucky paper. Optionally, the fullerene nanotubes may be derivatized with one or more ...
    • Fullerene triplet states in solution 

      Ausman, Kevin Douglas (1998)
      Triplet state pre-equilibration by reversible energy transfer has been observed by transient-absorption spectroscopy in mixed toluene solutions of C70 and C60 and of C70 and C60(CH 3)2. The equilibrium constants governing ...
    • Fullerene-based amino acids 

      Barron, Andrew R.; Yang, Jianzhong (2012-07-10)
      The present invention is directed to a series of new compounds, combining the unique properties of fullerenes and bio-active amino acid residues, and to methods for making such compounds. The present invention is directed ...
    • Fullerenol radical anions 

      Husebo, Lars Olav (2004)
      The first exhaustive purification and characterization of fullerenol samples, prepared by reaction of C60 in toluene with NaOH solution using tetrabutylammonium hydroxide as a phase transfer catalyst, have been performed. ...
    • Fully Integrated CMOS-Compatible Photodetector with Intrinsic Gain and Red-Green-Blue Color Selectivity 

      Zheng, Bob (2014-04-21)
      Currently, image sensors are hybrid devices, combining semiconductor photodiodes with off-chip color filters of different materials to convert wavelength-selected light into useful photocurrent. Here we demonstrate a fully ...
    • Fully integrated single-walled carbon nanotube thermoplastic composites 

      Rodriguez-Macias, Fernando J. (2004)
      The development of composites of single-walled carbon nanotubes (SWNTs) with thermoplastics requires methods for good dispersion and achieving good interaction between SWNTs and the matrix. This thesis presents a new method ...
    • Fully transitive polyhedra with crystallographic symmetry groups 

      Eisenlohr, John Merrick (1990)
      This dissertation sets forth a method for classifying, up to euclidean similarity, fully-transitive polyhedra which have crystallographic symmetry groups. Branko Grunbaum's definition of polyhedron is used, in which the ...
