Ni-Al-Superlegierungen sind bekannt für ihre guten mechanischen Eigenschaften unter hohen Temperaturen. Die elektrochemische Abscheidung von Ni mit Al-Nanopartikeln in LIGA-Strukturen und folgender Wärmebehandlung bietet die Möglichkeit, Ni-Al Superlegierungen für Hochtemperatur-LIGA-MEMS nutzbar zu machen. Über LIGA abgeschiedene Ni-Al-Mikrozugprüfkörper zeigen in Mikrozug- sowie Mikrokriechversuche eine verbesserte thermische Stabilität gegen plastische Verformung.

This thesis describes the first and long-sought successful synthesis of a new pyrazole-expanded porphyrin, a higher analog of porphyrin. This "Siamese-Twin Porphyrin" provides two conjoined porphyrin-like coordination spheres, thus being able to accommodate two metal ions within the same ligand. In her thesis, Lina Blusch not only explains the challenging synthesis and characterization of the ligand system, but also its application to the synthesis of homo- and hetero-bimetallic Ni and Cu complexes. She observes interesting metal-metal-interactions in the complexes, that lead to a non-innocent multistep redox chemistry. The ligand system and its complexes show an intriguing twisted geometry, giving rise to helical chirality and other fascinating properties. This study explores the first steps and opens up a new chemistry of expanded porphyrins with the potential to biomimetic applications.
