Stabilität und Kompatibilität des keramischen Interkonnektors der Hochtemperatur-Brennstoffzelle SOFC
[Juel-3723]
Jülich : Forschungszentrum Jülich, Zentralbibliothek, Verlag, Berichte des Forschungszentrums Jülich 3723, XI, 170 p. ()
Solid oxide fuel cells are operated at temperatures from 1073 K to 1273 K due to the use of ceramic materials as solid electrolyte. In view of the high temperatures and the required long operating times of at least 40000 hours particularly great demands are made on the stability and chemical compatibility of the materials used. [...]

Ortsaufgelöste Photostrommessungen (OBIC) am Halbleiter / Elektrolyt-Kontakt im Sub-Mikrometerbereich
[Juel-3715]
Jülich : Forschungszentrum Jülich, Zentralbibliothek, Verlag, Berichte des Forschungszentrums Jülich 3715, 218 p. ()
When a semiconductor is inserted into an electrolyte, a rectifying electrical contact is produced. This contact is suitable for converting solar into electrical or chemical energy. [...]

Engineered Rhodobacter capsulatus as a Phototrophic Platform Organism for the Synthesis of Plant Sesquiterpenoids
Sesquiterpenoids are a large class of natural compounds offering manifold properties valuable for food, cosmetics, agriculture, and pharma industry. Production in microorganisms is a sustainable approach to provide sesquiterpenoids for research and industrial use independent of their natural sources. [...]

Untersuchung von Widerstandsänderungen polykristalliner Dünnschichtelektroden bei Schwermetallabscheidungen
[Juel-3713]
Jülich : Forschungszentrum Jülich, Zentralbibliothek, Verlag, Berichte des Forschungszentrums Jülich 3713, IV, 125 p. ()
The lateral resistance of a thin metal film depends an the presence or absente of other species at the film surface. This phenomenon has been investigated regarding possible analytical applications for the determination of heavy metals in aqueous solutions. [...]

Hochtemperaturkorrosion von ferritischen und austenitischen Stählen in simulierten Rauchgasen kohlebefeuerter Kraftwerke
[Juel-3712]
Jülich : Forschungszentrum Jülich, Zentralbibliothek, Verlag, Berichte des Forschungszentrums Jülich 3712, 114 p. ()
In the present work the high temperature corrosion behaviour of three 9% Cr-steels in simulated coal combustion gases has been investigated. For comparison reason the conventional ferritic steels X 20 CrMoV 12-1 and 10 CrMo 9-10 as well as the austeniticX 3 CrNiMoN 17-13 were also incorporated in the research program [...]

Magnetic field dependence of the thermopower of Kondo-correlated quantum dots: Comparison with experiment
Signatures of the Kondo effect in the electrical conductance of strongly correlated quantum dots are well understood both experimentally and theoretically, while those in the thermopower have been the subject of recent interest, both theoretically and experimentally. Here, we extend theoretical work [T. [...]

Unitarity driven nonperturbative effects in deep inelastic scattering
[Juel-3710]
Jülich : Forschungszentrum Jülich, Zentralbibliothek, Verlag, Berichte des Forschungszentrums Jülich 3710, IV, 145 p. ()
We study several semi-inclusive production mechanisms in deep inelastic scattering and high energy hadronic scattering and their impact one the total virtual photoabsorption cross section (the structure function) as dictated by the unitarity relations for the scattering matrix. We first consider the $\overline{d} - \overline{u}$ asymmetry in the proton sea, driven by the pionic content of the proton [...]

Untersuchungen zum Sinterverhalten von dotiertem Wolframpulver
[Juel-3708]
Jülich : Forschungszentrum Jülich, Zentralbibliothek, Verlag, Berichte des Forschungszentrums Jülich 3708, II, 128 p. ()
Aim of this study was the investigation of the sintering behaviour of doped tungsten powder which is used for the production of incandescent lamp filaments. Therefore, an experimental set-up was constructed which allows direct current sintering of small tungsten bass in a special sample holder [...]
