Abstract: A paint-applied digital imaging system may include a plurality of small pixel devices each including a photodiode, a battery, and an antenna. The plurality of pixel devices may be suspended in a liquid dispersion medium, such as a transparent paint, and brushed or rolled onto an extended surface, such as a wall. Each photodiode collects light, charging its battery, which powers the antenna. The antenna transmits a signal indicating the intensity of light incident on the photodiode to a base station. The signals sent by the plurality of pixel devices are received by the base station and converted into a digital image.

Abstract: Graphene fibers made from a graphene film formed into an elongated fiber-like shape and composite materials made from the graphene fibers. The elongated fiber-like shape may be the graphene film in a rolled spiral orientation or the graphene film in a twisted formation. The graphene film has benzoxazine groups formed on at least an outer surface of the graphene film and epoxide groups formed on at least one edge of the graphene film. Methods of increasing strength of a composite material include combining a resin matrix with a plurality of the graphene fibers to form a prepreg material and curing the prepreg material to form the composite material.

Abstract: A method of making an indexed prepreg composite sheet is disclosed. The method comprises forming discrete regions in a resin film layer. The discrete regions are arranged in an indexing pattern. The method also includes forming a precursor prepreg composite sheet by impregnating a fiber reinforcement with the resin film layer having a viscosity. The discrete regions of the resin film layer form non-impregnated regions of the precursor prepreg composite sheet. The method additionally includes replacing the non-impregnated regions of the precursor prepreg composite sheet with indexing openings.

Abstract: A method for chemical vapor deposition on a substrate is disclosed. The method may include directing a process gas into a reaction chamber, and heating the process gas in the reaction chamber. Heating the process gas in the reaction chamber may decompose the process gas to thereby generate a plurality of decomposition products. The method may also include applying one or more biasing fields and/or waves to the process gas upstream of the substrate, and reacting the process gas with the substrate. The one or more biasing fields and/or waves may include electromagnetic waves, electric fields, and/or magnetic fields. The biasing fields and/or waves may urge at least a portion of the process gas towards or away from the substrate.

Abstract: A system (100) for making a prepreg composite sheet (300) comprising contoured charges (308) comprises first means (102) for forming precursor outline regions (206) in a resin film layer (200). The system (100) also comprises second means (106) for impregnating a fiber reinforcement (220), comprising fibers (222), with the resin film layer (200), comprising the precursor outline regions (206), to form the prepreg composite sheet (300). The prepreg composite sheet (300), as so formed, comprises non-impregnated outline regions (310) that define the contoured charges (308). The non-impregnated outline regions (310) in the prepreg composite sheet (300) correspond to the precursor outline regions (206) in the resin film layer (200). The system (100) further comprises third means (104) for guiding the fiber reinforcement (220) and the resin film layer (200) to the second means (106). The resin film layer (200) comprises the precursor outline regions (206) formed by first means (102).

Abstract: Composite materials are augmented with functionalized graphene having added amine groups, benzoxazine groups, imide groups, or a combination of amine groups and imide groups on a surface of the graphene, epoxide groups formed on at least one edge of the graphene and/or holes formed through the graphene. The functionalized graphene is integrated into a composite material as a supplement to or as a replacement for either the carbon reinforcement material or the resin matrix material to increase strength of the composite materials, and may be in the form of a functionalized graphene nanoplatelet, a flat graphene sheet or film, or a rolled or twisted graphene sheet or film.

Abstract: Systems and methods are provided for fabrication of enhanced carbon fiber laminates that utilize encapsulated catalyst. One embodiment is a method that includes acquiring a batch of dry fibers, and acquiring a batch of catalyst capsules that each comprise catalyst that accelerates polymerization of monomers of a resin, and a shell that encapsulates the catalyst and liquefies at a curing temperature. The method further includes interspersing the catalyst capsules among the dry fibers, and impregnating the fibers with the resin after interspersing the catalyst capsules with the fibers.

Abstract: A chemical vapor deposition (CVD) system for forming carbon nanotubes from solid or liquid feedstock. The system includes a reactor including a housing that includes an inlet and an outlet. The housing defines an interior for receiving the feedstock, and the interior receives inert gas. The CVD system includes a first stop valve in flow communication with the inlet and a second stop valve in flow communication with the outlet. The first and second stop valves seal the inlet and the outlet such that a static environment is formed in the interior when reacting the feedstock. A heater heats the interior to a temperature such that the feedstock is vaporized, thereby forming vaporized feedstock. The CVD system further includes a controller coupled in communication with the first and second valves and the heater. The controller is configured to selectively actuate the first and second valves and the heater.
