Research Interests

Current research activities focused on design and synthesis of mesoporous nanostructured materials and their applications, including:

• Nanoporous metal oxides using soft- or hard-templated 'nanocasting' self-assembly approaches
• Periodically ordered mesoporous polyoxometalates and transition metal-substituted polyoxometalates
• Nanostructured inorganic semiconductors
• Structural and chemical modification of nanocomposite frameworks
• Application in heterogeneous catalysis, adsorption and gas separation

Short Curriculum Vitae

Gerasimos Armatas received his B.Sc. in Chemistry from University of Ioannina in 1998. He obtained his master in Bioinorganic Chemistry in 2000 and his doctoral degree in Chemistry in 2003 from the same University. He did his PhD work with Prof. P. Pomonis on synthesis and pore structure determination of silicate mesoporous materials. From 2004 to 2006 he was a post-doctoral research associate at Chemistry Department of the Michigan State University in USA, working with Prof. Mercouri Kanatzidis on the synthesis of mesostructured elemental semiconductors such as silicon or germanium. While in 2006 he moved at Chemistry Department of the Northwestern University in IL, USA, where he worked on synthesis of mesoporous Ge-based intermetallic and metal chalcogenide semiconductors. In 2008 he was appointed Assistant Professor at the Department of Materials Science and Technology of the University of Crete.
