Nanomaterials, photocatalysis, supercapacitors, CO2 conversion, microwave absorbing & shielding materials


Giannakopoulou Tatiana received her Diploma in Radiophysics and Electronics including Quantum Radiophysics from the State Shevchenko University of Kiev in 1985. She earned her Ph.D. degree from the same university in 1993 performing thesis entitled “Polarization properties of the diffusely scattered coherent electromagnetic radiation”. She carried out her research on construction and optimization of automated Stokes polarimeters, on non-invasive polarimetric methods of the material investigation as a scientific researcher at Polarimetry Laboratory of the Kiev University from 1985 until 1996.Since 2000, she is with the NCSR Demokritos. At first, she was involved in research projects on the electromagnetic properties of ferromagnetic, ferroelectric and conductive polymer materials for design of the microwave absorbers with Sol-Gel Laboratory. Then, she joined the Laboratory of Nanofunctional and Nanocomposite Materials being engaged in different projects concerning such fields as photo-electrocatalysis and supercapacitors, metamaterials and EMI shielding as well as CO2 conversion to valuable materials. Her recent scientific interests are focused on structural, optical and electrochemical properties of semiconductors, graphene and 2D graphene-like nanostructures for environmental and energy applications. She has an experience in the description/calculation of thin semiconductor films via optical dispersion models, in the nanomaterial fabrication routes such as sol-gel, hydrothermal, electrochemical deposition and metallothermic reduction techniques and in the characterization techniques that include UV-visible light spectroscopy, conventional and attenuated total reflectance FT-IR, RAMAN spectroscopy, atomic force microscopy (AFM), scanning electron microscopy (SEM), cyclic voltammetry and electrochemical impedance spectroscopy. Giannakopoulou T. has ~59 publications in peer-reviewed scholar journals with ~2438 citations, h-index 28 (Google Scholar 20/12/2021).
