The huge availability of volcanic deposits in Mt. Etna volcano and the wide use materials as aggregates local architecture encouraged us to apply them alkaline environment produce geopolymeric binders restore historical buildings area. Two clusters samples for each precursor (volcanic ash ghiara paleo-soil) were produced, using 10 20% wt. metakaolin two different solutions based on sodium potassium respectively. A comparative study was made relation activators used, focusing evaluation...
In this work, we focused on the possibility of using clay sediments found in Sicily as precursors to produce alkali activated materials (AAMs) with properties comparable those traditional used construction. Two different clays were selected: Plio-Pleistocenic marly (PP) and Numidian Flysh (NU) test use without calcite. AAMs prepared thermally treated at 700 °C alkaline activator solutions NaOH 4, 6 8 M or sodium silicate. All samples cured 85 for 20 h room temperature 28d. Mineralogical...
Emerging evidence suggests that air pollution increases the risk of cardiovascular disease (CVD) and metabolic disorders, adding to global burden attributable lifestyle behavioral factors. Although long interspersed nucleotide elements 1 (LINE-1) methylation has been associated with these no studies have simultaneously examined effects diet exposure on DNA methylation. Herein, we evaluated association particulate matter (PM aerodynamic diameters less than 10 mm) adherence Mediterranean Diet...
Abstract Volcanic rocks have been used for building activity by the inhabitants of important cities located on slopes Mt. Etna, Italy. In this paper, potential use volcanic residues (code 20 03 03—“Municipal waste” from road cleaning in European Waste Catalogue (EWC)) production alkali activated material, especially devoted to restoration buildings belonging Baroque Sicilian architecture, was investigated. particular, large pyroclastic deposits recent eruptions considered waste materials...
Abstract A wide production of ecclesiastical artefacts is traceable in Sicily between the 17th and 19th centuries, admirable many diocesan museums. Nevertheless, these were never studied from an archaeometric point view: Beyond their historical value, it time to understand whether information concerning decorating gemstones reliable. In situ investigations through portable instrumentations (Raman spectroscopy X‐ray fluorescence) performed on gems monstrances, a reliquary, archbishop's...
The modern synthesis of Egyptian Blue has been attempted - mostly with success- by many researchers, since the scientific community working on this experimentation for more than a century. aim is that reconstructing chaîne opératoire used in past to produce pigment, among first synthetic ones history, whose colour due blue copper silicate cuprorivaite. Almost all experiments carried out up now sense have malachite or commercial CuO as source receipt, contrarily what stated Vitruvius who...
Micro-FTIR and FTIR spectroscopy is useful for the study of degradation forms cultural heritage. In particular it permits to identify phases establish structural relationship between them substratum. this paper, we report results obtained on marble from a Roman sarcophagus, located in medieval cloister St. Cosimato Convent (Rome), oolitic limestone facade Giuseppe Church Syracuse (Sicily). The main components found samples both monuments are: gypsum, calcium oxalate, organic matter due...
Abstract Alkali‐activated materials (AAMs) and “geopolymers” are inorganic polymeric obtained by mixing of solid aluminosilicate precursors with an alkaline solution (generally, KOH or NaOH Na 2 SiO 3 mixed in various ratios). This class has emerged as a greener alternative to traditional concrete, for large‐scale well niche applications such conservation restoration built heritage. In this work we apply Raman spectroscopy both (metakaolin, pumice, volcanic ash, soils, clayey sediments,...
This paper presents the chemical characterization of 79 fragments Archaic and Hellenistic fine‐grained pottery from archaeological sites in Messina, Catania, Lentini Siracusa (Sicily). The sherds were classified as ‘calcidian’, ‘banded’, ‘unvarnished’ ‘black varnished’ pottery. major trace elements identified by X‐ray fluorescence (XRF) statistically elaborated using method proposed J. Aitchinson 1986 for analysis compositional data. From cluster analyses element/SiO 2 log‐ratios, it was...
In recent years, the use of Raman spectroscopy as a gemological tool has largely increased, in particular conservation science field where non‐destructive and contactless identification is required. this work, we show large amount information which possible to obtain with analysis on one most important gems, emerald, green variety beryl. particular, 14 not certified faceted emeralds have been studied by means standard micro‐Raman spectrometer, allowing also some fakes (garnet, glass,...
In recent years, the use of mobile Raman equipment as an archeological, artistic, and conservation tool has largely increased due to possibility obtain quick nondestructive compositional analysis on precious, vulnerable, unique art objects. particular, archeological museums can take great advantage in carrying out situ measurements short times without moving artifacts. this work, we report carried by portable instruments important jewelry collection dated back 17th–18th centuries preserved...
This paper aimed to investigate the possibility of using alkaline-based binders made from industrial waste produced by ceramic tiles in field conservation and restoration monuments archaeological heritage. Geopolymer mortars, which are environmentally sustainable products obtained chemical consolidation at room temperature, studied for their versatility applications as reintegration or bedding mortars pre-cast elements, namely bricks, missing parts pottery, an alternative traditional not...
