  3. 12. The solar wind protons inside the induced magnetosphere of Mars

    Författare :Catherine Dieval; Maria Hamrin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Sammanfattning : Mars is an unmagnetized planet. Mars has no intrinsic magnetic field but has local magnetic anomalies in the crust. The solar wind, which is the plasma flowing from the Sun at supersonic speed, interacts with the magnetic fields of the currents induced in the conductive Martian ionosphere, deviates and slows down to subsonic speeds.

  4. 13. Protons in In-doped BaZrO3: incorporation, distribution and local environments

    Författare :Laura Mazzei; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrogen dynamics; hydrogen depth profiling; vibrational spectroscopy; neutron scattering; thin films; perovskites; Proton conductors;

    Sammanfattning : Acceptor doped proton conducting oxides are currently of large interest for their potential application as electrolyte materials in the future generation of solid oxide fuel cells. However, their proton conductivities are still lower than the target conductivity required for practical applications. LÄS MER

  5. 14. Alkylation and Hydrodearomatization over Zeolite cCatalysts

    Författare :Jun-Jun Yuan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acid catalysts; ZSM-5 catalysts; ethylbenzene; toluene; temperature; diesel fuel; hydrodearomatization; benzene; acidic protons; activity and selectivity; aqueous ethanol; Pt Y zeolite; gasoline; pressure; GC; diethylbenzene; Hydrocracking; SiO2 Al2O3 ratio; alkylation of aromatics; Brønsted acids;

    Sammanfattning : The alkylation of aromatic compounds is widely used in the large-scale synthesis of petrochemicals, and a great variety of fine chemicals and intermediates. Acid catalysts used for alkylation of aromatic hydrocarbons are Brønsted acids containing acidic protons. LÄS MER
