Der neue 6,0-l-Zwölfzylindermotor für den Audi A8

Autor: Andreas Möndel, Robert Müller, Helmut Endres, Armin Bauder, Ernst Gorenflo

Publikováno v: MTZ - Motortechnische Zeitschrift. 62:534-543

Der Audi A8 verbindet seit seiner Serieneinfuhrung in hohem Mase Prestige, Komfort und Sportlichkeit. Das Modell S8 mit dem 4,2-l-V8-Motor stellte bisher die starkste Motorisierung und ist auch weiterhin die sportliche Variante des A8-Modells. Mit de

Radical cation salts of an unsymmetrical BEDT-TTF derivative: DIMET

Autor: Andrea Kraatz, Helmut Endres, Stephan Gärtner, Dieter Schweitzer, Ilsabe Heinen, Emil Gogu, Klaus Bender, Heimo J. Keller, Rolf Heid

Publikováno v: Synthetic Metals

A surprising fact in the structures of the organic superconductors (TMTSF)2 Cl04 and -β-(BEDT-TTF)2X (X=I3-, IBr2- and AuI2-) is that there exists a slight dimerisation of the donor molecules within the stacks of these radical cation salts. Therefor

X-ray investigations of the low-temperature phases of the organic metals α- and β-(BEDT-TTF)2I3

Autor: Carl Krüger, Roman Swietlik, Klaus Angermund, Heimo J. Keller, Dieter Schweitzer, Helmut Endres

Publikováno v: Zeitschrift für Naturforschung, A: Physical Sciences

The structure of single crystals of the organic metals α- and β-(BEDT-TTF)2I3* was determined at 100 K, well below the phase transitions indicated by resistivity and thermopower measurements as well as by differential thermal analysis. In the α-ph

Preparation, structure and investigations of BEDT-TTF trihalides

Autor: Dieter Schweitzer, Emil Gogu, Klaus Bender, M. Hiller, Helmut Endres, Heimo J. Keller, Ilsabe Heinen

Publikováno v: Zeitschrift für Naturforschung, B: A Journal of Chemical Sciences

Crystals of the β-phases of (BEDT-TTF)2Br-I-Br (1) and (BEDT-TTF)2I-I - Br (2) have been isolated by electrocrystallization. The solids can be obtained using different tetrabutylammonium trihalides containing iodine and bromine as supporting electro
