  • Patent number: 9926201
    Abstract: A method, apparatus, and system for fabricating buckypaper or similar sheets of nanostructures having relatively high aspect ratios. A dispersion of nanostructures such as nanotubes is subjected to fluid dynamics/forces which promote alignment of their axes of elongation while in suspension in the flow. An agglomeration of better aligned nanostructures is isolated from the carrier fluid into a useable form. In the case of nanotubes, one form is buckypaper. One example of alignment forces is Taylor-Couette flow shear forces. One example of isolation is filtering the flowing dispersion to collect better aligned nanostructures across the filter into a sheet or film. The degree of alignment can produce anisotropic material properties that can be beneficially used in application of the sheet or film.

    Abstract: An identification label with a three-dimensional wrinkled structure may be formed by depositing a hard film with a high elastic modulus on an elongated substrate of a lower elastic modulus. Wrinkles with defects develop as the substrate is subsequently allowed to relax. Defects such as ridge endings and ridge bifurcations are randomly distributed over the wrinkled surface, and allow to uniquely identify any given identification label with the high degree of accuracy. Since the formation of defects is a random process, the wrinkled structure cannot be reproduced or counterfeited. The labels are thus forgery-proof.

  • Patent number: 8188575
    Abstract: Apparatus and methods for uniform metal plating onto a semiconductor wafer, such as GaAs wafer, are disclosed. One such apparatus can include an anode and a showerhead body. The anode can include an anode post and a showerhead anode plate. The showerhead anode plate can include holes sized to dispense a particular plating solution, such as plating solution that includes gold, onto a wafer. The showerhead body can be coupled to the anode post and the showerhead anode plate. The showerhead body can be configured to create a seal sufficient to substantially prevent a reduction of pressure in the plating solution flowing from the anode post to holes of the showerhead anode plate.

  • Publication number: 20120064236
    Abstract: The present invention has been aimed to propose a process and a device of fabricating a prepreg for a printed circuit board which are capable of controlling respective thicknesses of resin layers on the opposite surfaces of a resultant prepreg, removing air bubbles from the resultant prepreg, and improving productivity. The present invention is a process of resin-coating the opposite surfaces of an elongated substrate sheet 3. The process includes the steps of: feeding the substrate sheet 3 while tensioning the same in a feeding direction along the length of the substrate sheet 3; coating, by the coating head 2 of the first dispenser 1a, one surface of the substrate sheet 3 with the fluid resin 4 while pressing against the one surface to bend the substrate sheet 3; and subsequently coating, by the coating head 2 of the second dispenser 1b, the other surface of the substrate sheet 3 with the fluid resin 4 while pressing against the other surface to bend the substrate sheet 3.

  • Publication number: 20120043300
    Abstract: The present invention provides a description for an instrument for creating arrays of metal nanostructures allows on various substrates at the wafer scale. Embodiment methods permit for the formation of individual and arrays of metal alloys of nanostructures by bringing an array of liquid metal droplets droplet in contact with an array of metal patterns by using high precision manipulation mechanism. Top view and side view optical lenses are used to observe the manipulation process and also allow for aligning the metal droplets with film of solid metal patterns. As one example, this instrument is capable of pattering high aspect ratio nanostructures such as silver-gallium (Ag2Ga) nanowires onto prefabricated microstructures. This invention also describes a method for forming arrays of liquid metal droplets on the tip of micro structures by bringing a flexible membrane containing a liquid metal film, in contact with a pattern of microstructures.

  • Patent number: 8097297
    Abstract: In a method of manufacturing a flexible display substrate having reduced moisture permeability and reduced oxygen permeability, nanosized or microsized particles are uniformly dispersed in a molten polymer matrix. The molten polymer matrix are formed into plate-shaped molten polymer. The plate-shaped molten polymer is extruded between two extruding rollers to form a polymer or plastic sheet, to orient the nanosized or microsized particles in parallel with a surface of the polymer or plastic sheet. The polymer or plastic sheet is stretched between a glass transition temperature and a melting point to form a polymer or plastic film, exfoliating and orienting the nanosized or microsized particles further in parallel with a surface of the polymer or plastic film. The polymer or plastic film is coated with an organic film to flatten a surface of the flexible display substrate. Heat treatment is performed to cure the organic film.
