    Abstract: 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.

    Abstract: 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.

    Abstract: A system and method is available for fabricating a field emitter device, where in an emitter material, such as copper, is deposited over a resistive layer which has been deposited upon a substrate. Two ion beam sources are utilized. The first ion beam source is directed at a target material, such as molybdenum, for sputtering molybdenum onto the emitter material. The second ion beam source is utilized to etch the emitter material to produce cones or micro-tips. A low work function material, such as amorphous diamond, is then deposited over the micro-tips.

    Abstract: A field emitter comprising a conductive metal and a diamond emission tip with negative electron affinity in ohmic contact with and protruding above the metal. The field emitter is fabricated by coating a substrate with an insulating diamond film having negative electron affinity and a top surface with spikes and valleys, depositing a conductive metal on the diamond film, and applying an etch to expose the spikes without exposing the valleys, thereby forming diamond emission tips which protrude a height above the conductive metal less than the mean free path of electrons in the diamond film.
