CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
English18-Crown[6] has been used to prepare new organic–inorganic complexes with Cs2CO3 and aromatic mono-, di- and tricarboxylic acids (benzoic, isophthalic, terephthalic and trimesic acid).
