Elisabetta Sacco , Nikoletta Mila , and Vasilissa Nikonova , our three master’s students just graduated in Industrial Chemistry with theses on “Study and optimization of Ag-modified SrTiO3 photocatalysts with high thermal stability for NOx abatement under visible light”, “DEVELOPMENT OF PIEZO – ENHANCED PHOTOCATALYTIC MATERIALS FOR WASTEWATER REMEDIATION BY SOLAR LIGHT”, and “Development and optimization of easily recoverable materials for polyphenols recovery and/or their photodegradation” Congratulations! You did a great job!
