Various embodiments of the present disclosure pertain to methods of making carbon nanotube-coated substrates by dissolving carbon nanotubes in a solvent to form a carbon nanotube solution; and coating a surface of a substrate with the carbon nanotube solution to form one or more carbon nanotube layers on the surface of the substrate. The carbon nanotube solution may include a superacid solvent. A cable made out of the carbon nanotube-coated substrates may include one or more internal insulating layers that surround the surface of one or more internal conductors. Carbon nanotube solutions may be coated onto the one or more internal insulating layers to form one or more carbon nanotube layers. Additional embodiments of the present disclosure pertain to carbon nanotube-coated substrates formed by the methods of the present disclosure. The carbon nanotube-coated substrates may include one or more carbon nanotube layers derived from a carbon nanotube solution.

A slurry of the graphene oxides comprises the graphene oxides and a solvent. The graphene oxides include a strong graphene oxide and a weak graphene oxide. The slurry can be used to make composite films of graphene oxides and graphene heat-conducting films. The slurry includes two graphene oxides with different degrees of oxidation, which can increase a carbon content in the graphene oxide per unit mass, so that the finally obtained graphene heat-conducting film has more carbon.

The invention provides a transparent gas barrier polymer-glass-polymer laminated film comprising a first polymeric film substrate; a silicate glass layer, comprising silica and a salt of a monovalent cation other than Lithium, in combination with at least one additive selected from organo-silanes or an epoxy silane precursor, laminated onto said first polymeric film substrate; and a second polymeric film laminated on said glass layer; wherein the oxygen transmission rate through the laminated polymer-glass-polymer film is lower than 0.2 cc/m.sup.2/day and methods for the production thereof.

The present invention relates to coating of tubes, and more particularly to a system and method for coating and/or renovating deteriorated or pitted tubes to extend tube life and enhance performance. Using this system and method a thin coating is applied to the interior of a tube such that the coating is uniform in thickness and covers all regions of the tube. The coating material may be selected to minimize changes in heat transfer or may be selected to provide for the change in working fluid within the tube such that the working fluid does not negatively interact with the tube material.

A wiper system configured to apply and wipe one or more coatings on a rigid tube includes a tapered wiper tapering between a wider end defining an inlet orifice and a narrower end defining an exit orifice. The narrower end of the tapered wiper includes a series of slits arranged circumferentially around the exit orifice. The slits define a series of resilient tabs configured to deflect radially outward when contacted by one or more formations on an outer surface of the rigid tube and configured to return to a neutral position when the one or more formations have passed through the exit orifice. The wiper system may also include a gimbal supporting the tapered wiper. The gimbal is configured to permit the tapered wiper to rotate about first and second mutually perpendicular axes when the tapered wiper is contacted by a bowed rigid tube.

A balloon catheter that includes an elongated main body extending in an axial direction and a balloon connected to the distal portion of the elongated main body. The balloon includes an interior and is inflatable and deflatable. The balloon catheter also includes a plurality of elongate bodies extending radially away from the outer surface of the balloon. The elongate bodies are crystals of a water-insoluble drug. The elongate bodies each possess an independent longitudinal axis. Each of the elongate bodies includes a base portion at the proximal end of the elongate body. A plurality of elongate body proximal portions extend radially inwardly from the base portion of each of the elongate bodies toward the interior of the balloon. The elongate body proximal portions are continuous extensions of the crystal of the water-insoluble drug.

This invention relates to the repair and removal of erosion or impact damage with a liquid repair material using a flexible applicator capable of conforming to the surface of the leading edge of the airfoil while being drawn lengthwise along the airfoil surface of a helicopter or wind turbine rotor blade thereby restoring the aerodynamic contour with or without the addition of an optional topcoat layer.

Processes and devices useful in the application of coatings (14) to the interior of tubes (10) are described. Such processes (40, 400) may include applying a layer (20) of coating fluid (18) to the internal surface (16) of the tube (10) and passing a smoothing member (22) through the tube (10) at a distance from the internal surface (16). The viscosity of the coating fluid (18) may be selected so that the layer (20) of coating fluid (18) has a thickness substantially equal to or in excess of a predetermined wet film thickness (Twf) correlated to a desired final thickness (Tf) of the coating (14). The distance between the smoothing member (22) and the internal surface (16) may substantially correspond to the predetermined wet film thickness (Twf). The smoothing member (22) may smooth the coating fluid (18) and remove coating fluid (18) in excess of the wet film thickness (Twf) from the internal surface (16).
