Steinar Raaen

Steinar Raaen is a Professor in the Department of Physics at the Norwegian University of Science and Technology (NTNU), with his office located at Realfagbygget, E3-124, Gløshaugen, Høgskoleringen 5. His research bridges fundamental surface physics and applied biomaterials engineering, focusing on thin-film coatings for medical applications.

His primary research interests include Materials Science, Surface Science, and Biomedical Engineering, with specialization in hydroxyapatite-based coatings doped with antimicrobial elements (fluorine, chromium, copper, zinc, magnesium) for bone implants and drug delivery systems. He extensively utilizes plasma electrolytic oxidation (PEO) for titanium surface modification and investigates fundamental phenomena like gas adsorption on metal surfaces and electronic properties of 2D materials.

Analysis of his 2023-2025 publications reveals a dominant focus on developing drug-eluting biomaterials, particularly amoxicillin/tetracycline-loaded hydroxyapatite composites with enhanced antibacterial properties. A significant portion explores PEO-treated titanium alloys for improved osseointegration, while fundamental studies examine graphene-metal interfaces and surface reactions relevant to catalysis.

Professor Raaen maintains active international collaborations, particularly with Polish (Krzysztof Rokosz) and Romanian (Daniela Predoi, Simona Liliana Iconaru) research groups, as evidenced by his extensive co-authorship network across materials characterization and biomedical applications.
