Halloysite Nanotubes for Cleaning, Consolidation and Protection

2017

Herein, we report our recent research concerning the development of halloysite based protocols for cleaning, consolidation and protection purposes. Surface modification of halloysite cavity by anionic surfactants was explored to fabricate inorganic micelles able to solubilize hydrophobic contaminants. Hybrid dispersions based on halloysite and ecocompatible polymers were tested as consolidants for paper and waterlogged archaeological woods. Encapsulation of deacidifying and flame retardant agents within the halloysite lumen was conducted with aim to obtain nanofiller with a long-term protection ability. The results prove the suitability and versatility of halloysite nanotubes, which are per…

L’Ateneo di Palermo, da Università a L’Univercittà: un caso di comunicazione pubblica in Sicilia

2014

Se consideriamo l'istituzione universitaria come un soggetto che si muove nella società e che agisce in essa, confrontandosi costantemente con i suoi pubblici, interni ed esterni, e, più o meno direttamente, con gli altri atenei, e se riteniamo significante ogni tipo di azione, a prescindere dalla sostanza espressiva, non potremo fare distinzioni tra immagine e identità, tra comunicazione e reputazione: l'identità si dà solo attraverso unÊimmagine percepibile (espressione), e viceversa, l'immagine non può che comunicare un insieme di valori, cioè un'identità (contenuto). L'identità di un soggetto sociale, come un'istituzione, va considerata come l'esito finale di tutte le manifestazioni tes…

Il primo concorso per il Palazzo di Giustizia a Roma del 1884. Ricostruzione critica del progetto di Ernesto Basile

2019

1. Breve descrizione dell’oggetto di studio Il concorso del Palazzo di Giustizia di Roma si svolge in quattro fasi svolte tra il 1884 e il 1887. Il progetto per il primo concorso, del 1884, redatto dall’allora giovanissimo Ernesto Basile (Palermo 1857-1932), rivela una grande perizia progettuale che trasforma il complesso programma funzionale in un austero edificio in stile neofiorentino. I disegni originari dell’opera, non realizzata, conservati presso la Dotazione Basile del Dipartimento di Architettura dell’Università di Palermo, sono stati oggetto di studio propedeutico alle fasi di analisi, interpretazione e ricostruzione congetturale del modello digitale. 2.

Objectives pursued and achieved Conjectural reconstruction achieved the following results: • formulation of analytical documents which show how the planimetric and altimetric articulation are perfectly consistent with the functional program• definition of the level of uncertainty1. Brief description of the object of study The competition of the Palace of Justice in Rome takes place in four phases between 1884 and 1887. The project for the first competition in 1884 drawn up by the then very young Ernesto Basile (Palermo 1857-1932) reveals a great deal of design expertise that transforms the complex functional program into an austere building in neo-florentine style. The original drawings of the building not realized kept in the Basile Endowment of the Department of Architecture of the University of Palermo have been the subject of preliminary study to the phases of analysis interpretation and conceptual reconstruction of the digital model. 2. State of the art and main bibliographical references The conjectural reconstruction on the basis of drawings and archival documents is a well-established and codified practice thanks to various disciplinary contributions at national and international level.
