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.

A controlled, material-independent and adaptable cold wet chemical procedure is described. It allows organic and inorganic compounds to be confined inside multi-wall carbon nanotubes. The procedure mainly consists of a lyophilization process to fill multi-wall carbon nanotubes (MWCNTs), and a washing method to clean their outer surface without removing the encapsulated material. The technique was tested by synthesizing CdS crystals inside the nanotubes. Morphological and structural studies of the CdS crystals demonstrated a complete control of the synthesis process, and the possibility of maximizing the crystal size and the filling efficiency that approached 70% of open-ended nanotubes.
