摘要： A two-layer nanotape that includes a nanoribbon substrate and an oxide that is epitaxially deposited on a flat surface of the nanoribbon substrate is described. The oxide is deposited on the substrate using a pulsed laser ablation deposition process. The nanoribbons can be made from materials such as SnO2, ZnO, MgO, Al2O3, Si, GaN, or CdS. Also, the sintered oxide target can be made from materials such as TiO2, transition metal doped TiO2 (e.g., CO0.05Ti0.95O2), BaTiO3, ZnO, transition metal doped ZnO (e.g., Mn0.1Zn0.9O and Ni0.1Zn0.9O), LaMnO3, BaTiO3, PbTiO3, YBa2Cu3Oz, or SrCu2O2 and other p-type oxides. Additionally, temperature sensitive nanoribbon/metal bilayers and their method of fabrication by thermal evaporation are described. Metals such as Cu, Au, Ti, Al, Pt, Ni and others can be deposited on top of the nanoribbon surface. Such devices bend significantly as a function of temperature and are suitable as, for example, thermally activated nanoscale actuators.

摘要： A product in which at least a portion of the product has a nanocrystalline microstructure, and a method of forming the product. The method generally entails machining a body in a manner that produces chips consisting entirely of nano-crystals as a result of the machining operation imposing a sufficiently large strain deformation. The body can be formed of a variety of materials, including metal, metal alloy and ceramic materials. Furthermore, the body may have a microstructure that is essentially free of nano-crystals, and may even have a single-crystal microstructure. The chips produced by the machining operation may be in the form of particulates, ribbons, wires, filaments and/or platelets. The chips are then used to form the product. According to one aspect of the invention, the chips are consolidated to form the product, such that the product is a monolithic material that may contain nano-crystals. According to another aspect of the invention, the chips are dispersed in a matrix material, such that the product is a composite material in which the chips serve as a reinforcement material.

摘要： Dendron ligands or other branched ligands with cross-linkable groups were coordinated to colloidal inorganic nanoparticles, including nanocrystals, and substantially globally cross-linked through different strategies, such as ring-closing metathesis (RCM), dendrimer-bridging methods, and the like. This global cross-linking reaction sealed each nanocrystal within a dendron box to yield box-nanocrystals which showed dramatically enhanced stability against chemical, photochemical and thermal treatments in comparison to the non-cross-linked dendron-nanocrystals. Empty dendron boxes possessing a very narrow size distribution were formed by the dissolution of the inorganic nanocrystals contained therein upon acid or other etching treatments.

摘要： Methods of fabricating uniform nanotubes are described in which nanotubes were synthesized as sheaths over nanowire templates, such as using a chemical vapor deposition process. For example, single-crystalline zinc oxide (ZnO) nanowires are utilized as templates over which gallium nitride (GaN) is epitaxially grown. The ZnO templates are then removed, such as by thermal reduction and evaporation. The completed single-crystalline GaN nanotubes preferably have inner diameters ranging from 30 nm to 200 nm, and wall thicknesses between 5 and 50 nm. Transmission electron microscopy studies show that the resultant nanotubes are single-crystalline with a wurtzite structure, and are oriented along the direction. The present invention exemplifies single-crystalline nanotubes of materials with a non-layered crystal structure. Similar “epitaxial-casting” approaches could be used to produce arrays and single-crystalline nanotubes of other solid materials and semiconductors. Furthermore, the fabrication of multi-sheath nanotubes are described as well as nanotubes having multiple longitudinal segments.
