  • Publication number: 20210308934
    Abstract: A method for making a nanoimprinted perovskite film or a perovskite crystal. The method includes applying a solution onto a substrate, thereby forming a precursor film or a precursor crystal, wherein the solution comprises an organo-metal halide precursor in a solvent. The method also includes fabricating an organo-metal halide perovskite film or an organo-metal halide perovskite crystal, wherein fabricating includes annealing the precursor film or the precursor crystal, thereby at least partially evaporating the solvent. The method also includes imprinting the organo-metal halide perovskite film or the organo-metal halide perovskite crystal with a mold, thereby forming an imprinted film or an imprinted crystal. The method also includes separating the mold from the imprinted film or the imprinted crystal, thereby forming the perovskite film or the perovskite crystal.

  • Patent number: 10196271
    Abstract: A nanofiber yarn that includes a plurality of nanofibers twisted into a yarn along an alignment axis. The nanofibers of the plurality of nanofibers have a ratio of nanofiber length to nanofiber circumference of at least 50. The yarn has a helix angle measured relative to the alignment axis of from 5° to 30°. The yarn has tensile strength of at least 280 MPa. A nanofiber fabric that includes a first sheet of multiwalled nanotubes and a second sheet of multiwalled nanotubes on the first sheet of multiwalled nanotubes. The multiwalled nanotubes of the first sheet are aligned in a first direction. The multiwalled nanotubes of the second sheet are aligned in the first direction. The first sheet and the second sheet are aligned so that the multiwalled nanotubes of the first sheet and the second sheet are both aligned in the first direction.

  • Patent number: 9862607
    Abstract: Fabricating a nanofiber sheet, ribbon, or yarn by a continuous process that includes synthesizing a nanofiber forest in a forest growth region on a substrate, wherein the nanofiber forest comprises a parallel array of nanofibers, and further includes drawing said nanofibers from the nanofiber forest to form a primary assembly that is a sheet, ribbon or yarn. The substrate continuously moves from the furnace growth region into a region where the nanofibers in the forest are drawn.

  • Patent number: 9845554
    Abstract: The present invention is directed to nanofiber yarns, ribbons, and sheets; to methods of making said yarns, ribbons, and sheets; and to applications of said yarns, ribbons, and sheets. In some embodiments, the nanotube yarns, ribbons, and sheets comprise carbon nanotubes. Particularly, such carbon nanotube yarns of the present invention provide unique properties and property combinations such as extreme toughness, resistance to failure at knots, high electrical and thermal conductivities, high absorption of energy that occurs reversibly, up to 13% strain-to-failure compared with the few percent strain-to-failure of other fibers with similar toughness, very high resistance to creep, retention of strength even when heated in air at 450° C. for one hour, and very high radiation and UV resistance, even when irradiated in air. Furthermore these nanotube yarns can be spun as one micron diameter yarns and plied at will to make two-fold, four-fold, and higher fold yarns.
