    Ein Prognosemodell für die Verwitterung von Sandstein (2021)
    KIT Scientific Publishing
    Details
    Publication Date: 2024-04-11
    Description: Sandstone is the most common kind of natural stone used for historic buildings in Central Europe. During the past century a dramatic increase in different types of damage to historic buildings, monuments and sculptures made from natural stone has been observed. The present work deals with theoretical aspects of strength loss, fracture processes and degradation during the decay processes.

    KIT Scientific Publishing
    Details
    Publication Date: 2024-04-11
    Description: Several experimental campaigns are conducted to find feasible fiber reinforcements for buildings under earthquake conditions. Therefore tensile tests for the description of the bonding behavior of the fibers, shear tests on three-stone small specimen, small static cyclic shear wall tests, bending tests of wall segments, large format dynamically loaded wall plates and five building experiments were performed under realistic time history acceleration. At the end a calculation method is proposed.

    Influence of elevated temperatures up to 100 °C on the mechanical properties of concrete (2021)
    KIT Scientific Publishing
    Details
    Publication Date: 2024-04-11
    Description: Experiments to characterize the effects of moisture content and temperature on the mechanical properties of concrete were conducted. Based on these experiments, a new overall material model capable of predicting the mechanical behaviour of concrete subject to elevated temperatures up to 100 °C was developed. The material model estimates the time, temperature and moisture dependency of the compressive and tensile strength, creep and shrinkage of concrete.

    Coating and drying processes for functional films in polymer solar cells - from laboratory to pilot scale (2021)
    KIT Scientific Publishing
    Details
    Publication Date: 2024-04-11
    Description: Polymer solar cells can be produced by a continuous low cost coating and drying process. This work details a specialized experimental set-up to enable large scale roll to roll processing. Material properties such as surface energy, surface tension, and viscosity are presented and modelled. The impact of coating method, as well as process parameters (e.g. coating speed, shear rate, solvent composition) on process stability and film properties, is discussed.

    Catalytic soot oxidation by platinum on sintered metal filters. Influence of the platinum quantity, particle size and location, and investigation of the platinum-soot contact (2021)
    KIT Scientific Publishing
    Details
    Publication Date: 2024-04-11
    Description: The great challenge for next years concerning the emission of diesel engines is to develop diesel particle filters (DPF) with catalytic regeneration systems. This work is focused on the global understanding of the diesel soot oxidation on sintered metal filters (SMF). Platinum is studied as reference catalyst. The first objective is to determine which of platinum quantity, platinum particle size, or platinum location exhibits the preponderant influence on the catalytic.

    KIT Scientific Publishing
    Details
    Publication Date: 2024-04-11
    Description: Viele Talauen sind sowohl für die Gewinnung von Trinkwasser aus Grundwasser, als auch für die Schaffung von Hochwasserrückhalteräumen geeignet. Im vorliegenden Leitfaden werden die Prozesse des Stofftransports von der fließenden Welle über den Retentionsraum bis zu den Entnahmebrunnen eines Wasserwerks vorgestellt. Es wird deren Einfluss auf ein höheres Risiko der Verunreinigung der Grundwasserressource durch den Eintrag von Schadstoffen aus den Retentionsräumen diskutiert.
