Prof. Hosemann is interested in experimental material science for nuclear applications. His main focus is on structural materials used for nuclear components (fission, fusion, spallation, etc.). His research focuses on developing a basic understanding of the materials degradation processes in a nuclear environment and resulting consequences to engineering application.

Currently the focus is on three subjects:

• Small scale materials testing on irradiated and unirradiated structural materials for nuclear applications. It is the aim to reduce the necessary sample volume to a minimum in order to assess the materials state while investigating the basic effects of radiation damage. The same techniques developed are also deployed on evaluating non nuclear coatings.
• Investigating new advanced structural materials concepts (e.g. oxide dispersion strengthened steels, SiC.SiC composites, coating systems) using accelerated materials testing.
• extreme envrionment corrosion (e.g. Liquid metal corrosion, molten salt corrosion, etc.)  for nuclear applications. Development of a fundamental understanding of the involved mechanisms will lead to the development of improved alloying concepts and system operating techniques to reduce the corrosion issue.
