Utilized 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 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...
The outdoor sculpture of the first Portuguese king, D. Afonso Henriques (~1109 – 1185 AD), placed in Guimarães (North Portugal) is one of the most emblematic national sculptures. Created in 1887 by António Soares dos Reis, it possesses a remarkable symbolic value in the presumed birthplace of the king. In addition to the artistic and heritage importance of the monument, it is one of the few sculptures cast by a...

This paper presents the application of an established XRF-MC (X-ray fluorescence-Monte Carlo) protocol to evaluate for the first time the thickness of pictorial layers in illuminated manuscripts. A previously investigated, sixteenth-century book printed in Paris (BPE, Inc. 438) was chosen as the case study: multiple analysis spots were scanned in selected areas (painted and unpainted) with p-XRF (hand-held XRF)...

In this paper we present a case of a double burial (T.310/326) from the Phoenician Punic necropolis of Monte Sirai (Carbonia, Sardinia, Italy). This peculiar tomb, which comprises the inhumation of a woman, presents unique constructive features, namely a big stone cover that confers a high visual reference to the necropolis. Furthermore, a cooking pot with two handles was laid on the tibias during the final clo...
This work is part of a broader research line that aims to develop and implement a nondestructive methodology for the chemical characterization of archaeological metals based on a protocol that combines energy dispersive X-ray fluorescence spectrometry (ED-XRF) with a Monte Carlo (MC) simulation algorithm. In this paper, the ED-XRF-MC protocol has been applied to estimate the chemical composition of a selected g...
This study is part of a wide-scale research on metal production in South-Western al-Andalus during the Islamic period, under the project “DE RE METALLICA - DEfining and REdiscovering MEtallurgy and Trade in AL-Andalus (8th–13th centuries AD): Leaping into Innovative Comprehensive Archaeometric Approaches”. In particular, this paper presents the results of the elemental analysis carried out on a group of six Isl...
In this study, Monte Carlo (MC) simulations combined with energy dispersive X-ray fluorescence (EDXRF) spectroscopy have been used to characterize non-destructively a collection of Cu-based artifacts recovered from two archeological sites in southern Portugal: (a) the Chalcolithic E.T.A.R. site of Vila Nova de Mil Fontes and (b) the Middle Bronze Age site of Quinta do Estácio 6. The metal artifacts show a multi...
