Abstract

My research interest is focused on the synthesis and characterization of electroceramics materials with interesting electrical properties. The work involves the study of   oxides as electrodes for lithium batteries and Chemical-Biological sensors. The main used techniques are X-Ray diffraction, Electron microscopy and Impedance Spectroscopy. As a second research line I also studied intercalation chemistry and physical properties of nanocomposites based on Chalcogenophosphates type MPS3 (M= Mn, Cd).
