    Abstract: An electrospinning apparatus and methodology is described that produces medical devices, such as scaffolds that induce the formation of a natural fibrous structure (primarily collagen and elastin) in a tissue-engineered medical device. The apparatus uses collection surfaces designed to manipulate or change the electrostatic field so that the electrospun fibers are arranged in desirable patterns that are similar to or mimic the fibrillar structure of an animal tissue. The manipulation results in fibers that are preferentially oriented in a predefined pattern. In addition, the interfiber space between the fibers and the fiber diameter are consistently within a predefined range. Using these techniques in conjunction with controlling polymer properties enables the production of a scaffold that has the structural and mechanical characteristics similar to the native tissue.

  • Publication number: 20140319712
    Abstract: A plasma device for production of metal powder includes a reaction vessel, a plasma torch, a carrier gas supply unit and a cooling tube. A metal starting material is supplied to the vessel. The torch produces plasma between the torch and the metal starting material to evaporate the metal starting material and produce a metal vapor. The supply unit supplies into the vessel a carrier gas for carrying the metal vapor. The cooling tube is provided with indirect and direct cooling sections and cools the metal vapor transferred from the vessel to produce the metal powder. The metal vapor and/or the metal powder are indirectly cooled in the indirect cooling section and directly cooled in the direct cooling section. A projection and/or a recess are disposed at least on a part of an inner wall of the indirect cooling section.

  • Publication number: 20140293513
    Abstract: The disclosure describes an improved electrode with high voltage standoff characteristics and improved graphene-based materials and methods of making them for use therein. A graphene-based thin film material is described that may be applied or transferred to a current collector to create the improved electrode. The thin film comprises high aspect ratio graphene platelets applied to the surface of a current collector or other substrate in a known ratio to a film binder material. The film is produced with a desired layer thickness and graphene-to-binder ratio to produce a desired voltage standoff for the electrode. The film may include additional materials to achieve the desired dielectric and mechanical characteristics for the application, such as ferroelectric ceramic nanorods with a high aspect ratio and high dielectric constant and/or graphene sheets.

  • Publication number: 20140217630
    Abstract: Disclosed herein is a method to produce multiphase composite materials directly from solution precursor droplets by a fast pyrolysis process using a microwave plasma embodiment containing a microwave generating source, a dielectric plasma torch, and a droplet maker. Here, using homogenous solution precursors, droplets are generated with a narrow size distribution, and are injected and introduced into the microwave plasma torch with generally uniform thermal path. The generally uniform thermal path in the torch is achieved by axial injection of droplets into an axisymmetric hot zone with laminar flows. Upon exposing to high temperature within the plasma with controlled residence time, the droplets are pyrolyzed and converted into particles by quenching with a controlled rate of the exhaust gas in a gas chamber. The particles generated have generally uniform sizes and uniform thermal history, and can be used for a variety of applications.
