  • Patent number: 9331198
    Abstract: We have demonstrated controlled growth of epitaxial h-BN on a metal substrate using atomic layer deposition. This permits the fabrication of devices such as vertical graphene transistors, where the electron tunneling barrier, and resulting characteristics such as ON-OFF rate may be altered by varying the number of epitaxial layers of h-BN. Few layer graphene is grown on the h-BN opposite the metal substrate, with leads to provide a vertical graphene transistor that is intergratable with Si CMOS technology of today, and can be prepared in a scalable, low temperature process of high repeatability and reliability.

  • Patent number: 9058798
    Abstract: Tunable polymer-based sonic structures (“TuPSS”) are made up of sonic structures and polymers. The TuPSS has three general requirements: a) The sonic structure is composed of one or materials engineered to behave as a lens, filter, cloak, or dampener; b) Stimulus sensitive polymer is incorporated into the sonic structure; and c) The actuation of the polymer tunes the acoustic behavior of the structure in a predictable manner. The tunable polymer-based sonic structures utilize stimuli-driven physical properties of the polymers in these acoustic structures to produce a stimulus driven, or tunable, sonic structure or device. The sonic structures actively modulate mechanical vibrations that propagate through the structures, but are passive in that they do not produce mechanical vibrations. The stimuli for the structures include electric, magnetic, electromagnetic, chemical, thermal, and shaking/orientation.

  • Publication number: 20140332915
    Abstract: Direct growth of graphene on Co3O4(111) at 1000 K was achieved by molecular beam epitaxy from a graphite source. Auger spectroscopy shows a characteristic sp2 carbon lineshape, at average carbon coverages from 0.4-3 monolayers. Low energy electron diffraction (LEED) indicates (111) ordering of the sp2 carbon film with a lattice constant of 2.5 (±0.1) ? characteristic of graphene. Six-fold symmetry of the graphene diffraction spots is observed at 0.4, 1 and 3 monolayers. The LEED data also indicate an average domain size of ˜1800 ?, and show an incommensurate interface with the Co3O4(111) substrate, where the latter exhibits a lattice constant of 2.8 (±0.1) ?. Core level photoemission shows a characteristically asymmetric C(1s) feature, with the expected lr to lr* satellite feature, but with a binding energy for the three monolayer film of 284.9 (±0.1) eV, indicative of substantial graphene-to-oxide charge transfer.

  • Publication number: 20140296249
    Abstract: Dopamine D3 receptor antagonists and partial agonists are known to modulate the reinforcing and drug-seeking effects induced by cocaine and other abused substances. By introducing functionality into the butylamide linking chain of the 4-phenylpiperazine class of ligands, improved D3 receptor affinity and selectivity, as well as water solubility, is achieved. A series of linking-chain derivatives are disclosed wherein functionality such as OH, OAc, and cis or trans-cyclopropyl groups have been introduced into the linking chain. In general, these modifications are well tolerated at D3 receptors and achieve high selectivity over D2 and D4 receptors.
