Abschlussarbeiten für Studierende

Wir bieten für Studierende diverse Abschlussarbeiten in verschiedenen Themenbereichen der chemischen Materialsynthese an. Themenmöglichkeiten bestehen im Kontext der Batteriematerialien, deren Recycling, der Entwicklung neuer funktionaler Materialien mit schaltbaren Eigenschaften (Magnetismus, Supraleitfähigkeit, optische Eigenschaften) und elektrokatalytisch aktive Materialien für Brennstoffzellen. Bei Interesse kontaktieren Sie bitte Prof. Clemens per Email (oliver.clemens@imw.uni-stuttgart.de), der Sie gerne an einen möglichen Betreuer zu diesem Themenkomplex verweisen kann.

 

We offer topics for students in the field of materials science addressing various aspects of material synthesis and characterization. These topics are in the context of battery materials and their recycling, tunable and tailored functional properties (e.g., superconductivity, magnetism, optical properties), as well as electrocatalysts for fuel cells. If you’re interested, please contact Prof. Clemens via Email (oliver.clemens@imw.uni-stuttgart.de), who will create a contact for a potential supervisor of respective topics.
