    Description / Table of Contents: Zusammenfassung Der Umsatz von Xanthobilirubinsäuremethylester mit Brom in Methanol ergibt in 20-prozentiger Ausbeute ein rotes Pigment, für das die bislang nicht bekannte 16,24-Dehydrobiladien-ab-Konstitution abgeleitet wurde. Darüber hinaus konnte das entsprechende Mesobiliverdin-XIIIα, Mesobilirubin-XIIIα, 14-Formyltripyrrinon, und zwei diastereomere 15,16-Dimethoxybiladiene-ab aus der Reaktionsmischung isoliert werden. Die mechanistischen Aspekte dieser Reaktion werden diskutiert.
    Notes: Summary On treating xanthobilirubic acid methyl ester with bromine in methanol, a red bile pigment, which was assigned the hitherto unknown 16,24-dehydrobiladiene-ab constitution, is obtained in 20% yield. In addition, the corresponding mesobiliverdin-XIIIα, mesobilirubin-XIIIα, 14-formyl-tripyrrinone, and two diastereomeric 15,16-dimethoxybiladienes-ab could be isolated from the reaction mixture. The mechanistic aspects of this reaction are discussed.

    Active vibration control of smart composites featuring electro-rheological fluids (1995)
    Springer
    Applied composite materials 2 (1995), S. 59-65

    ISSN: 1573-4897

    Notes: Abstract Our experimental investigations are focused on evaluating the elastodynamic response characteristics of a beam fabricated in an electrorheological fluid when the beam is subjected to forced vibration. The beam which is designed in this experiment is composed of three kinds of materials, i.e. structural material, damping material and sealant material. Different ratios of structural material to damping material have been tested in an applied electric field. The results demonstrate clearly the ability to significantly change the vibrational characteristics of a beam fabricated in a smart composite by changing the electric field intensity imposed on the fluid domains. The ASTM standard E756-83 equations are used to evaluate the Young's modulus of the beam.

    Dynamic characteristics of a beam specimen featuring electrorheological fluids (1997)
    Springer
    Experimental mechanics 37 (1997), S. 1-4 
    Details
    ISSN: 1741-2765
    Keywords: Smart material ; electrorheological fluid ; dynamic test

    Notes: Abstract The experimental investigations are focused on evaluating the elastodynamic response characteristics of beams fabricated in electrorheological (ER) fluids when the beams are subjected to forced vibration. The beams used in this experiment are composed of three kinds of materials: structural material, damping material and sealant material. Beams with different ER fluids and different structural material are made and tested. The results demonstrate clearly the ability to significantly change the vibrational characteristics of beams fabricated in smart composites by changing the electric field intensity imposed on the fluid domains. With the ASTM standard E756-83 equations, the Young's modulus of the beams and the shear modulus of ER fluids are evaluated.
