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.
