Synchrotron-based diffraction-enhanced imaging and diffraction-enhanced imaging...
Schiavon, Nicola; Rao, Donepuri; Brunetti, Antonio; Gigante, Giovanni Ettore; Zhong, Zhong; Cesareo, RobertoUtilized the upgraded Synchrotron-based non-destructive Diffraction-enhanced imaging and Diffraction-enhanced imaging coupled with CT X-ray imaging systems to image the chickpea seeds, to enhance the contrast in plant root architecture, visibility of fine structures of root architecture growth and some aspects of physiology at acceptable level. DEI-CT images were acquired with 30 keV synchrotron X-rays. A serie...
Synchrotron-based transmitted, Compton and fluorescence photons from phantom ma...
Schiavon, Nicola; Rao, Donepudi; Gigante, Giovanni Ettore; Cesareo, Roberto; Brunetti, AntonioSynchrotron-based transmitted, Compton and fluorescence photons from phantom materials composed of light elements, for example, Water, PMMA, Polyethylene, Bakelite, Muscle and Bone, are evaluated, using 10, 15, 20, 30 and 40 keV synchrotron X-rays. The SYRMEP beam line facility at Elettra is used as a source of X-rays. The present research is focused to assess the contribution of transmitted, Compton and fluore...
Tracing Local Production and Agricultural Trade: A Multi-Analytical Study of Ro...
Schiavon, Nicola; Buraca, Ida; Oliveira, Cesar; Bottaini, Carlo; Correia, Virgilio Hippolito; Mirao, José; Beltrame, MassimoAmphorae are a significant type of Roman pottery, serving as both transport containers and indicators of economic and technological practices across the Empire. Despite their importance in interpreting local economic dynamics in Roman Lusitania, the production origins, technological characteristics and functional roles of amphorae from Conímbriga in Portugal remain poorly understood. Previous research has focus...
The use of powdered olive stone in lime-based mortars for the conservation of c...
Schiavon, Nicola; Zicarelli, Maria Antonietta; Adomako, Regina; Ruffolo, Antonio SIlvestro; Giordano, Francesca; Macchia, AndreaThis research paper investigates the use of Powdered Olive Stone (POS), an agricultural by-product, as a partial replacement for quartz sand in lime-based mortars used for the repair and conservation of historical structures. POS offers a potential solution, addressing waste disposal and reducing reliance on traditional aggregates. This study specifically focuses on lime-based mortars, one of the most commonly ...
Plasma enhanced chemical vapor deposition (PECVD) of SiOx thin films on Portugu...
Schiavon, Nicola; Ding, Yufan; Grassini, Sabrina; Angelini, EmmaPlasma Enhanced Chemical Vapor Deposition (PECVD) of SiOx thin films has been applied to the stone surface under laboratory conditions in order to assess its feasibility as an alternative method for stone protection. SiOx thin layers were deposited on oolitic limestone lithologies known to have been used for the construction and restoration of the Batalha Monastery in Portugal surface by PECVD from tetraethoxys...
Islamic Middle Ages Pottery from Quintã de Muge, Serradinho Archaeological Site...
Schiavon, NicolaDuring the Islamic period, ceramic workshops were commonly established in settlements throughout the Gharb al-Andalus region (Western Iberia at the time), to produce ceramics for local supply. Along the middle valley of the Tagus river (i.e., nowadays central Portugal), hundreds of Islamic ceramic sherds, either glazed or common wares, were recovered over different archaeological excavations. At the archaeologi...

Archaeo-Material Study of the Cuneiform Tablet from Tel Beth-Shemesh
Fossé, Cécile; Yogev, Jonathan; Mirão, José; Schiavon, Nicola; Goren, YuvalThe Fifth Haverford excavation season at Tel Beth-Shemesh (Ain Shams) in 1933 revealed a fractured tablet bearing a cuneiform inscription dating to the Late Bronze Age. Considered to be the earliest alphabetic cuneiform text uncovered in the Canaanite arena outside of Ugarit, this tablet quickly became the focus of many studies. Later readings suggested that this was the earliest example of a South Semitic Alph...
Challenges in laser cleaning of cultural heritage stained glass
Schiavon, Nicola; Maingi, Evan Maina; Pilar Abad, Maria Alonso; Treil, Valerie; De La Fuente, Xerman; Angurel, Luis; Chapoulie, Remy; Rahman, MD AshiqurStained-glass windows play an important role in cultural heritage. Human and environmental factors have subjected these pieces to risks of damage. Mechanical and chemical- based cleaning methods have been used for their restoration and conservation. Additionally, short-pulse lasers have opened new opportunities for safe and controlled cleaning and restoration of these important materials. In this work, ultra-sh...
Beyond Technology: Pottery Reveals Translocal Social Relations at a Bell Beaker...
Schiavon, Nicola; Gaspar, Adam; Petrik, Jan; Fojtik, Pavel; Tsoupra, Anna; MIR-MAKHAMAD, Basira; Cardoso, Ana Margarida; Mirao, José; Beltrame, MassimoThe Bell Beaker site near Brodek u Prostejova (Czechia) has yielded remains of a large timber construction accompanied by four symmetrical ritual deposits with numerous artefacts, including more than fifty ceramic vessels. Their decoration consists of incised patterns, in nineteen cases with preserved white inlaid incrustations. To investigate the social relations at this extraordinary site, a multi-analytical ...
