Sull’attuazione degli obblighi internazionali di risposta e ripresa a fronte della pandemia di Covid-19: una prospettiva italiana
2023
This work aims at offering a critical analysis of how Italy, as one of the most early-affected countries, has responded to and is currently recovering from the Covid-19 pandemic, in the framework of international and European obligations applicable to CBRN events at large. To this end, this article will first examine the main obligations concerning «response» to and «recovery» from a pandemic event, as stemming from relevant international and European law instruments. Then, it will look at how these obligations have been implemented by Italian central and local authorities vis-à-vis the Covid-19 pandemic, while also offering some conclusive remarks on the legal meaning of the «disaster mana…
Palermo Living Lab on the road
2017
“Re-cycle Palermo Lab on the road”, esperienza iniziata nel 2013 e giunta alla sua terza edizione, è dedicata alla visita critica di luoghi ed esperienze e allo scambio di riflessioni con studiosi che concorrono alla declinazione dei paradigmi e degli strumenti di un nascente Re-cycling Urbanism. Il contributo racconta l’iniziativa che ha coinvolto gli studenti del Laboratorio di Urbanistica Creative City del Dipartimento di Architettura dell’Università degli Studi di Palermo, tenuto dal prof. Maurizio Carta, che hanno aderito alla Ricerca Nazionale “Re-Cycle Italy. Nuovi cicli di vita per architetture e infrastrutture della città e del paesaggio”, sperimentando diverse modalità di approccio…
Re-forming Rome exhibition: a pedagogical machine
2017
Il contributo descrive il contributo dell'Unità di ricerca di Palermo alla mostra “Roma 20-25. Nuovi cicli di vita della metropoli”, inaugurata il 18 dicembre 2015 nella sala Claudia Gian Ferrari del Museo MAXXI di Roma, occasione di confronto con le altre 24 università internazionali che hanno aderito al progetto. Per un mese, la mostra è stata anche l’occasione per mostrare al pubblico gli esiti del progetto Roma 20-25, un mese in cui i visitatori hanno potuto osservare i 25 progetti proposti per Roma, interrogarsi sul futuro della città e sul loro potenziale come attori del processo mentre apprezzavano la ricchezza di visioni, pensieri, approcci e linguaggi differenti di cui ogni scuola …

The title compound, [Ir(η5-C5Me5)Cl(C18H14ClN3)]B(C6H5)4, is chiral at the metal center and crystallizes as a racemate. In the cation, the hydrazinylidenepyridine ligand isN,N-coordinated through theN-pyridyl andN-hydrazinylidene groups forming a five-membered metallacycle. An intramolecular C—H...Cl hydrogen bond is observed. In the crystal, centrosymmetrically-related cations are connected by C—Cl...π interactions, forming a dimeric structure. The crystal packing is further stabilized by weak interionic C—H...π interactions.
Diethyl (1-benzyl-4-phenyl-3-trifluoromethyl-1H-pyrrol-2-yl)phosphonate

In the title compound, C22H23F3NO3P, the dihedral angles between the pyrrole ring and the benzyl and phenyl rings are 81.38 (7) and 46.21 (8)°, respectively. The ethyl phosphate groups present with P—O—C—C torsion angles of −178.47 (10) and 106.72 (16)°, and an intramolecular C—H...O hydrogen bond occurs. In the extended structure, molecules are linked by C—H...O and C—H...F hydrogen bonds to generate [001] chains.

The title compound, C12H20N2OSe, crystallizes in strands of enantiomeric molecules connected via O—H...N hydrogen bonds. There are only slight deviations from an ideal gauche conformation in the decamethylene chain, indicating just a little strain.
rac-12-Selena-13,14-diazatricyclo[9.3.0.02,4]tetradeca-11,13-diene
2020
The centrosymmetric crystal structure of the title compound, C11H16N2Se, is built up from alternating strands of (R,R)- and (S,S)-enantiomers. These strands, which propagate along the c-axis direction, are composed of homochiral molecules related to each other by twofold screw axes. The shape of the molecule is an almost planar unit around the selenadiazole ring with a hexamethylene chain as an arched handle.
