  • Publication number: 20100328411
    Abstract: A system and method of ink-jet printing on vinyl print media can comprise jetting an ink-jet ink onto a vinyl print medium to form a printed image, and applying from 50-100° C. of heat to the printed image. The ink-jet ink can include a colorant, an aqueous liquid vehicle, and core-shell polymer particles. Upon printing and heating, at least a portion of the aqueous liquid vehicle evaporates, the vinyl print medium plasticizes (but does not flow), and the ink-jet ink flows. The fused polymer particles form a film that encapsulates at least a portion of the colorant.

  • Patent number: 7833616
    Abstract: A self-aligning nanowire includes a nanowire portion and an aligning member attached to the nanowire portion. The aligning member interacts with another aligning member on an adjacent self-aligning nanowire to align the nanowires together. A method of aligning nanowires includes providing a plurality of the self-aligning nanowires, suspending the plurality in a carrier solution, and depositing the suspended plurality on a substrate. An ink formulation includes the plurality of suspended self-aligning nanowires in the carrier solution. A method of producing the self-aligning nanowire includes providing and associating the nanowire portion and the aligning member such that the nanowire produced is self-aligning with another nanowire.

  • Patent number: 7622371
    Abstract: A thin film semiconductor and a method of its fabrication use induced crystallization and aggregation of a nanocrystal seed layer to form a merged-domain layer. The nanocrystal seed layer is deposited onto a substrate surface within a defined boundary. A reaction temperature below a boiling point of a reaction solution is employed. A thin film metal-oxide transistor and a method of its production employ the thin film semiconductor as a channel of the transistor. The merged-domain layer exhibits high carrier mobility.

  • Patent number: 7482253
    Abstract: Crystal growth performed in situ facilitates interconnection of prefabricated nano-structures. The nano-structures are immersed in a growth solution having a controllable saturation condition. Changing the saturation condition of the solution modifies a size of the immersed nanowires. The solution includes a solute of a nano-structure precursor material. The saturation condition is changed to one or both etch material from a surface of the nano-structures and initiate crystal growth on the nano-structure surface. A nano-structure interconnection system includes the growth solution and equipment to deposit the prefabricated nano-structures on a substrate. An interconnected structure includes a plurality of nano-structures disposed on a substrate in a cluster and a liquid phase-grown crystal lattice on surfaces of the nano-structures to form physical interconnections between the plurality. An ink formulation includes the plurality of nano-structures suspended in the growth solution.

  • Publication number: 20090004588
    Abstract: Photoconductor structure processing methods and imaging device photoconductor structures are described. According to one embodiment, a photoconductor structure processing method includes processing a photoconductor structure of an imaging device and wherein the photoconductor structure comprises charge transport material configured to conduct electrical charges generated responsive to reception of light to form a latent image during an electro-photographic imaging process, the processing comprising removing at least some of the charge transport material from at least a portion of the photoconductor structure. The photoconductor structure may also be further treated to reduce the migration of charge transport material. Additional embodiments are described in the disclosure.

  • Publication number: 20080182011
    Abstract: An ink formulation of a circuit element includes a first powder having a first melting temperature, a second powder having a second melting temperature that is higher than the first melting temperature, and a polymer binder. A method of fabricating a circuit element on a substrate employs the ink formulation and includes depositing the ink formulation on a substrate, curing the polymer binder, and melting the first powder at the first melting temperature to yield a solid solution that forms the circuit element.
