Ilias Papailias successfully completed his studies in Chemical Engineering at the National Technical University of Athens in 2008. His thesis entitled "Evaluation of the antioxidant activity of phenolic derivatives by fluorescence" was held at the Institute of Physical Chemistry of NCSR "Demokritos". This was followed by the fulfillment of his military service obligations, where he gained experience as a chemist. From 2011 to 2014 he worked in the private sector in areas of production and quality control. Since summer 2014, he works at the Nanofunctional and Nanocomposite Materials Laboratory at the Institute of Nanoscience and Nanotechnology of NCSR "Demokritos" for the PhotoTiGRA project entitled "Photoactive TiO2/Graphene containing paints for air purification". Since the beginning of 2015 he also participates in the IKYDA 2015 project entitled "Development of TiO2/Graphene nanocomposites for photocatalytic hydrogen production". At the same time, he works on his PhD which is based on new photocatalytic nanocomposite materials.
