BIOGRAPHY
Prof. SALADINO is Associate Professor at Department of Biological, Chemical, and Pharmaceutical Sciences and Technologies (STEBICEF) of University of Palermo. She is graduated in Chemistry in 2001 and she got the PhD in Chemical Sciences in 2008. She is author of 67 publications in ISI Journals and 30 publications on proceedings books and books. She is co-inventor of a Patent in Italy (N. 102016000029804, 22/03/2016) “Composizione per la deacidificazione e la riduzione della carta e relativo metodo per il restauro della carta”. She is the scientific coordinator of the Canaletto Project “Multianalytical approach for the dating and authentication of archaeological ceramics“ financed by the Executive Programme for Scientific and Technological Cooperation Between the Italian Republic and The Republic of Poland for the years 2019-2020 and Editor for the Special Issue “Materials and Methods in Cultural Heritage: the role of Archaeometry in Museums” of Heritage in 2019 (ISSN 2571-9408).
The research activity is related to the development of innovative nanostructured materials, such as luminescent nanoparticles, mesoporous silica materials, polymer nanocomposites and controlled release systems for the protection of stone surface and the deacidification for ancient papers. She is also involved in the development of analytical methods for the investigation of artefacts in the field of Cultural Heritage, by using non invasive techniques and multianalytical approaches.
ABSTRACT
Preventive conservation of stone by using nanostructured materials
In the last two decades, several innovative materials like nanostructured materials have been developed and applied for the restoration and conservation of artefacts of archaeological and artistic interest. Their particular properties make this class of compounds very interesting and useful, mainly in all the circumstances where the size of the materials needs to be controlled to achieve the best results.
However, before and after their application, the characterization of the artefacts, where they are applied, is one the essential step in order to design, verify and assess their action.
In this presentation, some examples of development and application of nanostructured materials for the stone preventive conservation to some case studies are described. In particular:
- nanolime dispersions applied on the Graffiti of the Steri prison in Palermo (Italy) [1];
- mesoporous silica, both in micro and nanometric size, as controlled release systems of biocides against the biodeterioration. The better systems have been used to treated the fountain in Diamantina (Minas-Gerais, Brazil) [2] and a paintings at Grotta di Santa Margherita, Castellammare del Golfo (Trapani, Italy).
- protective polymeric dispersions of different chemical composition, also embedded with titania nanoparticles, on the “Cusa’s stone” used to build the greek archeological Temples of Selinunte (Trapani, Italy).
Since all works can be considered unique in their kind and relevant for the historical period to which they belong and present different problems, the study of the artefact has been carried out before the application of the nanostructured materials.
