Abstract: A method of producing one or both of carbon nanotubes (CNT) and hydrogen in the reaction zone of a rotary tube reactor or a fluidized bed reactor that has an outlet. The reaction zone is heated to a reaction temperature between 60° and 900° C. A CNT catalyst is provided into the reaction zone at the reaction temperature. The CNT catalyst includes a transition-metal active catalyst supported on metal oxide particles having a high specific surface area. A process gas is flowed through the reaction zone. The process gas is a gaseous mixture of a hydrocarbon and hydrogen. The hydrocarbon includes at least one of methane, ethane, propane, butane, iso-butane, propene, 1-butene, 2-butene, and iso-butene. The hydrocarbon decomposes at the catalyst sites into CNT and hydrogen. Hydrogen is separated from the gases that exit the reactor through the reactor outlet.

Abstract: Carbon nanotube (CNT) hybrid materials and methods of making such materials. A carbon nanotube (CNT) hybrid powder material includes a mesh of CNTs intimately interspersed with particles of a second material. In an example the material includes a blend that itself includes particles of a metal oxide supported catalyst and particles of a second material, and a mesh of CNTs is grown on the supported catalyst in the blend. The mesh of CNTs is effective to disperse the particles of the second material.

Abstract: This disclosure includes, and results in the creation of, a printed carbon nanotube and/or graphene hybrid antenna and/or EMI shield, comprised of a conductive layer that comprises a metal mesh (MM) layer or a nanowire layer on a substrate, with a printed Signal Enhancement Layer (SEL) on the conductive layer. The SEL includes an ink that includes one or both of carbon nanotube (CNT) and graphene. The circuit pattern results after the “exposed” conductive layer (i.e., the regions where the CNT/graphene ink is not printed) is removed via chemical etching or mechanical cutting. The structure (the antenna/EMI shield) is preferably but not necessarily transparent.
