  • Publication number: 20130299415
    Abstract: An RF inductor such as a Tesla antenna splices nanotube ends together to form a nanostructure in a polymer foam matrix. High Internal Phase Emulsion (HIPE) is gently sheared and stretched in a reactor comprising opposed coaxial counter-rotating impellers, which parallel-align polymer chains and also carbon nanotubes mixed with the oil phase. Stretching and forced convection prevent the auto-acceleration effect. Batch and continuous processes are disclosed. In the batch process, a fractal radial array of coherent vortices in the HIPE is preserved when the HIPE polymerizes, and helical nanostructures around these vortices are spliced by microhammering into longer helices. A disk radial filter produced by the batch process has improved radial flux from edge to center due to its area-preserving radial vascular network. In the continuous process, strips of HIPE are pulled from the periphery of the reactor continuously and post-treated by an RF inductor to produce cured conductive foam.

  • Patent number: 8568838
    Abstract: A method of controlling power applied to an induction coil assembly used for densifying porous articles with a liquid matrix precursor. The control of applied power addresses dynamic changes in the electrical characteristics of the porous article being densified as it becomes denser. In particular, the power applied is controlled in accordance with changes in resonant frequency of the coupled system of the induction heating system and the porous article.

  • Publication number: 20130280642
    Abstract: A method of manufacturing a proton conducting fuel cell composite membrane includes the step of electrospinning a non-charged polymeric material, such as PVDF and PSF, into fiber mats. The fibers are fused to one another to provide a welded porous mat. The welded porous mat is filled with proton conducting electrolyte, such as PFSA polymer, to generate a proton conducting composite membrane. The resulting proton conducting fuel cell membrane comprises a randomly oriented, three dimensional interlinked fiber lattice structure filled with proton conducting electrolyte, such as PFSA polymer.

  • Patent number: 8551374
    Abstract: The invention relates to a novel, innovative industrial method for producing polystyrene (EPS) foam parts of arbitrary length and having a constant cross-section, with mixed densities located in accordance with the mechanical and thermal properties required for each application. The invention also relates to a machine (apparatus) for producing said solid parts having localized densities defined by the mechanical and thermal requirements of the application. The aforementioned products are produced by joined both longitudinally and transversely. The invention can be used to reduce the standard method to three steps, thereby resulting in a significant saving in terms of production. Moreover, unlike with the standard method, variants can be produced using the above-mentioned method, thereby increasing the range of application said type of products.

  • Publication number: 20130231623
    Abstract: A wound dressing including a hydrophilic layer and a hydrophobic layer is described. The hydrophilic layer absorbs exudate from a wound and the hydrophobic layer absorbs the exudate from the hydrophilic layer and traps the exudate. Because the hydrophilic layer is used adjacent to the wound, the exudate is readily absorbed thereby reducing the risk of maceration and infection of the wound tissue by the exudate. The hydrophobic layer receives the absorbed exudate from the hydrophilic layer and traps the exudate through an interaction that in turn prevents lateral diffusion of the exudate through the bandage to healthy portions of the skin. The hydrophilic and hydrophobic layers are fabricated from polymer fibers that can be spun to include components that facilitate wound healing, such as poly(hexamethylene biguanide) and/or hyaluronic acid.

  • Publication number: 20130168903
    Abstract: There are provided a method and apparatus for forming a three-dimensional image. The method and apparatus adjust the density in consideration of the influence of the expansion of a thermally expandable layer on the density of a display color or a color development state so that the originally planned density of the display color can be achieved, on the surface of a thermally expandable sheet. The method and apparatus form a mirror image of a colored image, of which the density of a black component is adjusted so as to correspond to the bulge height of the thermally expandable layer, on the back of the thermally expandable sheet. The method and apparatus expand the thermally expandable layer when irradiating the thermally expandable layer with light, which includes infrared wavelengths, from the back of the thermally expandable sheet.
