Georgios Pantazidis

During his PhD studies, Georgios Pantazidis researched the interaction of C60 molecules with hydrogen and oxygen atoms on graphitic surfaces, in experiments that mimicked interstellar environments. Georgios Pantazidis investigated the production of an interstellar dust-grain-mantle analogue and probed reactions on its surface. The formed species on this analogue, were more thermally stable, more chemically complex and the surface more reactive towards atomic species. The new research findings contribute to the understanding of interstellar dust grain surface morphology in terms of its role in the growth of the dust grain and the enrichment of chemically complex species formed via surface reactions.

The PhD study was completed at the Department of Physics and Astronomy, Aarhus University.

This summary was prepared by the PhD student.
