  • Publication number: 20190381475
    Abstract: The problem addressed by the invention is that of providing a plasma reactor for decomposition of hydrocarbons which allows stable operation over a prolonged time period. This problem is solved by a plasma reactor for decomposing a hydrocarbon fluid, which comprises a reactor chamber surrounded by a reactor wall and further comprises at least one hydrocarbon inlet and an outlet. A plasma torch having at least two electrodes, which comprise a base part at a first end, is fixed to the reactor wall. At a second end, the electrodes comprise a burner part which projects into the reactor chamber, and a plasma zone is defined between the burner parts of adjacent electrodes. In a region between the plasma zone and the outlet, the hydrocarbon inlet opens into the reactor chamber, and the hydrocarbon inlet is oriented toward the plasma zone such that hydrocarbon fluid flowing therefrom is directed towards the plasma zone.

  • Patent number: 8258501
    Abstract: A method of using a metal complex as an n-dopant for doping an organic semiconducting matrix material in order to alter the latter's electrical characteristics is provided. In order to provide n-doped organic semiconductors with matrix materials having a low reduction potential, while achieving high conductivities, the n-dopant is a neutral electron-rich metal complex with a neutral or charged transition metal atom as a central atom and having at least 16 valence electrons. The complex can be polynuclear and can possess at least one metal-metal bond. At least one ligand can form a ? complex with the central atom, which can be a bridge ligand, or it can contain at least one carbanion-carbon atom or a divalent atom. Methods for providing the novel n-dopants are provided.

  • Publication number: 20050139810
    Abstract: The invention relates to the use of an organic mesomeric compound as organic dopant for doping an organic semiconducting matrix material for varying the electrical properties thereof. In order to be able to handle organic semiconductors more easily in the production process and to be able to produce electronic components with doped organic semiconductors more reproducibly, a quinone or quinone derivative or a 1,3,2-dioxaborine or a 1,3,2-dioxaborine derivative may be used as a mesomeric compound, which under like evaporation conditions has a lower volatility than tetrafluorotetracyanoquinonedimethane (F4TCNQ).
