Quality evaluation of grapes for mechanical harvest using vis NIR spectroscopy
2019
Mechanical harvest of grapes is one of the operations that mostly influence the quality of the future wine. The shaking frequency of the harvesting machine is usually adjusted on the basis of the grape berry characteristics in order to limit grape juice production that is a potential cause of uncontrolled fermentations. These evaluations usually require time, personnel and laboratory analyses. The introduction of a vis NIR system to rapidly and reliably evaluate the berry properties in field before mechanical harvest could be a good alternative. The aim of this study was to evaluate the feasibility of applying vis NIR spectroscopy as a non-destructive technique on grapes cv. Syrah and Chard…
A Combined Non-Destructive and Micro-Destructive Approach to Solving the Forensic Problems in the Field of Cultural Heritage: Two Case Studies
2021
The present paper discusses the importance of non-destructive and micro-destructive technology in forensic investigations in the field of cultural heritage. Recent technological developments and the wide availability of modern analytical instrumentation are creating new possibilities for performing scientific measurements and acquiring data directly on-site—thereby limiting, where possible, sampling activity—as well as learning about the technologies and materials that were employed in the past to create cultural assets. Information on periods, chemical composition, manufacturing techniques, etc., can be gathered more easily. Overall, the benefits of on-site forensic investigations are mult…
Il cratere attico a fondo bianco del Pittore della Phiale al Museo Archeologico di Agrigento: primi dati da un’indagine composizionale sui pigmenti
2019
Il cratere attico a fondo bianco del pittore Phiale (440 a.C.), esposto al Museo Archeologico "Pietro Griffo" di Agrigento è un manufatto di grande raffinatezza. Raffigura il mito di Perseo e Andromeda ed è molto interessante sia per l'iconografia che per la tecnica pittorica generalmente documentata su lekythoi e vasi più piccoli. La presente ricerca interdisciplinare si è concentrata sulla tecnica pittorica di questo cratere ed è stata condotta direttamente al Museo mediante tecniche spettroscopiche non invasive e non distruttive (fluorescenza a raggi X e TRFTIR). Lo studio, di cui presentiamo qui i risultati preliminari, intende definire la natura del terreno bianco e pigmenti (secondo b…
