On the 18th of April, some of our Ph.D. students attended the XX PhD-Chem Day held in Pisa at the Congress Centre “Le Bendettine” and organised by CIRCC (Consorzio Interuniversitario Reattività chimica e catalisi - www.circc.it). During this national event, the PhD students Marco Rollo and Elisabetta Rosadoni had the opportunity to present their research works entitled “Lewis/Brønsted acidic deep eutectic solvents for plastic waste depolymerization” and “Selective C-H arylation of non-substituted imidazo[2,1-b]thiazole: towards a modular approach for biologically active compounds”, respectively.
