VALUTAZIONE DELL'EFFICACIA E DURABILITÀ DI PROTETTIVI NANOSTRUTTURATI APPLICATI SU CAMPIONI DI MARMO DI CARRARA
2014
An integrated analytical approach can be useful to study the effectiveness of preservation treatment for Carrara marble surfaces, carried out for testing commercial products which are based on nano-structured silica oxides. Variation in hydrophobic properties, porosity distribution, and chemical composition of treated surfaces have been studied. With this aim, contact angle evaluation, NMR, XRF measurements have been used. Changes of above mentioned physical and chemical characteristics have been evaluated before and after aging in saline chamber of the treated and untreated samples. Moreover, the effectiveness of ultrasonic treatment in “safe” removal of the products from treated surfaces …
PRODOTTI NANOSTRUTTURATI PER LA PROTEZIONE DI SUPERFICI LAPIDEE: VALUTAZIONE DELL’EFFICACIA MEDIANTE TECNICHE FISICHE NON INVASIVE
2014
The use of nanoproducts in the Cultural Heritage (CH) field requires great sensitivity and responsibility and, above all, analytical research and studies evaluating effectively their potential use. In order to evaluate the capability of nanostructured protective in the CH field, limestone materials of historical-artistic interest were treated and then studied. The study focuses on the non-invasive evaluation of samples stone, of interest in the CH field, their surface has been tested with nanostructured products. In particular, samples of limestone of Favara (Sicily) have been studied, before and after artificial aging. The analytical methodology involved X-ray fluorescence measurements, in…
Nanotecnologie per le costruzioni: nuovi materiali ed edifici dalle alte prestazioni
2011
In architecture and building practise, the development of new materials such as the nanostructured materials, and especially the nanocomposite materials, will lead to a huge revolution in the way architects and engineers think about planning and building as well as living inside new high-performance structures. New materials, new construction procedures and technologies, new structures will allow us construct higher and bigger enhanced buildings, structures and infrastructures with new and enhanced functionalities and perspectives. In this study we will analyze how these new technologies will change, or are still changing, the construction world.

VANTAGGI, RISCHI E PRECAUZIONE PER I PRODOTTI NANOSTRUTTURATI
2010
I Nanomateriali rappresentano il più attraente orizzonte per l'innovazione tecnologica. Siamo circondati da prodotti che impiegano la nanomateria e che migliorano sensibilmente, seppur almeno apparentemente, la qualità della nostra vita. Ma quale sono i rischi che si celano dietro l'innovazione del terzo millennio? Il contributo riferisce di studi, ricerche e convegni relativi alla produzione di materiali nanotecnologici in riferimento ai rischi possibili per la salute dell'uomo e per la salvaguardia dell’ambiente. Il Regolamento della Commissione europea sulla registrazione, valutazione, autorizzazione e restrizione di chimiche, in particolare l’art. 7, suggerisce il “principio di precauzi…
