1 - Metal oxide nanoparticles
Fundamental studies (exchange coupling at AFM-FM interfaces) and applications as catalysts and theranostic agents. Synthesis by thermal decomposition. Functionalization by ligand exchange. Nanoscale morphology (TEM), structure (ED, HRTEM), chemical composition (EELS, ESI, EDX); magnetometry (SQUID); colloidal stability (DLS and Z potential). Software for analysis of TEM (pebbles.istm.cnr.it) and HRTEM images, DLS correlograms and magnetometric data.
2 - Computational chemistry
Investigation of reactivity focusing on the site- and regio-selection, of 1.3-dipolar cycloadditions using three theoretical tools: conceptual DFT, computational DFT, and post-SCF ab-initio calculations. Our studies always carried out in parallel with experimentation in order to understand the selectivity mechanisms and optimize the synthetic outcome. Recently, we applied these methods to reactions catalyzed by nanoparticles.
Alessandro Ponti received his MSc in Chemistry and PhD in Chemical Sciences from the University of Milano. After a post-doc stay at the ETH in Zurich, he joined the Consiglio Nazionale delle Ricerche where he now is Director of Research at SCITEC. His main research interests are magnetic nanoparticles (synthesis and application to catalysy and nanomedicine), permanent magnets (recycle, new materials), and computational chemistry (investigation of chemical reactivity). He is member of AIMagn and of the Editorial Board of the journal Molecules
