Christos Trapalis, PhD, Chemical Engineer - Director of Research and Head of “Nanofunctional and Nanocomposite Materials Laboratory”, NCSR Demokritos. His scientific interests are focused on nanoscience and nanotechnology, carbon based materials, functionalized graphene and graphene oxide, 2D heterostructures, nanostructured powders and coatings, visible light active photocatalysts for NOx removal, water splitting, solar fuels, CO2 to nanocarbons conversion and hybrid organic–inorganic materials. Christos has taught “Physical Chemistry”, “Technology of Polymers”, “Technology of Glass and Ceramics” at HTEI Athens (1994-2004). He has been elected Prof. of “Advanced Materials” at the Department of Products Design Engineering, AEGEAN University (2004-8), but decided to continue the research activities at NCSR Demokritos. He taught also “Physical Chemistry” at the Hellenic Open University (2009-14) and “Anti-pollution Processes“(2015-now). During the last 15 years he participated in more than 20 research programs, coordinated more than 15 of them and raised for NCSR Demokritos more than 2,5 M€.

Christos is reviewer of more than 40 scientific journals with more than 140 publications in peer reviewed journals, 6100 citations, 6 patents, h-factor 41 and i10-index 84.
