    摘要： An improved coating for optical fibers is described. The present invention is a dimensionally precise and uniform coating with low-porosity. The improved coating is applied via sputtering within a vacuum chamber. Environmental conditions are monitored within a cylindrical magnetron during sputtering. Sputtering is adjusted or temporarily ceased when environmental conditions approach a damage threshold. Sputtered particles within a plasma cloud are dimensionally similar and adhere to an optical fiber in a volume efficient arrangement forming a more precise, denser, and more adherent coating. Embodiments of the present invention provide improved pull strength by compressively constraining the optical fiber within the coating and by closing microcracks.

    摘要： Disclosed are a variety of self-supporting, multilayer carbon films that include a layer of both a non-diamond-like carbon, for example, graphitic or amorphous carbon (or a-C), and a layer of diamond-like carbon (DLC). A wide range of multilayer configurations may be constructed depending on the particular combination of properties desired in the final product including, for example, a tri-layer construction including a single DLC layer sandwiched between two layers of amorphous carbon. Also disclosed are example embodiments of methods for producing such composite multilayer films that include preparing an appropriate substrate to include a deposition surface of sufficient smoothness, applying a parting or release agent to the deposition surface, depositing a plurality of layer carbon layers including both an amorphous carbon layer and a DLC layer to form the composite carbon film and removing the composite carbon film from the substrate.

    摘要： The present application is directed to siRNA-based silencing of the type II receptor of TGFβ. siRNAs that target this receptor abrogate the receptor protein and transcript, TGFβ-mediated processes such as fibronectin assembly and cell migration also are inhibited and the molecules of the invention are efficacious in reducing the inflammatory response and matrix deposition. These findings show that siRNAs can be successfully delivered both in vitro and in vivo to regulate the TGFβ type II receptor level and modulate wound response. Methods and compositions exploiting the findings of the present invention have a wide-ranging application, extending from treatment of disorders of the eye to other organs and tissues throughout the body.

    摘要： A field emission cathode for use in flat panel displays is disclosed comprising a layer of conductive material and a layer of amorphic diamond film, functioning as a low effective work-function material, deposited over the conductive material to form emission sites. The emission sites each contain at least two sub-regions having differing electron affinities. Use of the cathode to form a computer screen is also disclosed along with the use of the cathode to form a fluorescent light source.
