Mr. Antonaropoulos George
Ph.D. student

My aim is to optimize the growth of transition metal oxide hybrid nanocrystals by cost-effective and environmentally friendly, colloidal chemistry approaches and produce nanoparticle-assembled extended structures, with tunable properties that can yield materials for technological applications (e.g. sensors or memories). The produced nanoparticles are characterized by an armory of complementary methods, including, Spectroscopy, Transmission Electron Microscopy and X-ray diffraction.

Ph.D. dissertation carried out at IESL-FORTH, entitled "Optimization of Iron Oxide Nanocrystals' Response: Structural Disorder and Magnetically-Mediated Functionalities" (2021); degree awarded by the University of Crete (Dept. of Chemistry)
