20110123852 | Thin Film Electrodes and Battery Cells, and Methods of Fabrication - Thin-film electrodes and battery cells, and methods of fabrication. A thin film electrode may be fabricated from a non-metallic, non-conductive porous support structure having pores with micrometer-range diameters. The support may include a polymer film. A first surface of the support is metalized, and the pores are partially metallized to create metal tubes having a thickness within a range of 50 to 150 nanometers, in contact with the metal layer. An active material is disposed within metalized portions of the pores. An electrolyte is disposed within non-metalized portions of the pores. Active materials may be selected to create an anode and a cathode. Non-metalized surfaces of the anode and cathode may be contacted to one another to form a battery cell, with the non-metalized electrolyte-containing portions of the anode facing the electrolyte-containing portions of the cathode pores. A battery cell may be fabricated as, for example, a nickel-zinc battery cell. | 05-26-2011 |
20110206928 | Reinforced Fibers and Related Processes - A reinforced fiber is disclosed including a base material composed of a reinforcement ply having interstitial spaces; and a bacterial cellulose interwoven over the reinforcement ply and throughout the interstitial spaces. The reinforced fiber is obtained by (a) providing a base material composed of a reinforcement ply having interstitial spaces; and (b) contacting the base material with an effective bacteria in a microbial fermentation synthesis process for a time period sufficient to grow bacterial cellulose throughout the interstitial spaces of the reinforcement ply thereby providing a reinforced fiber interwoven with the bacterial cellulose. Also disclosed reinforced silicon carbide-containing nanofibers and processes for their preparation. | 08-25-2011 |
