Use of portable devices and confocal Raman spectrometers at different wavelength to obtain the spectral information of the main organic components in tomatoes (Solanum Lycopersicum) fruits
(Elsevier, 2013-03-15)
Tomato (Solanum lycopersicum) fruit samples, in two ripening stages, ripe (red) and unripe (green), collected from a cultivar in the North of Spain (Barrika, Basque Country), were analyzed directly, without any sample ...
Homogeneity assessment of the SuperCam calibration targets onboard rover perseverance
(Elsevier, 2022-05-29)
The SuperCam instrument, onboard the Perseverance rover (Mars 2020 mission) is designed to perform remote analysis on the Martian surface employing several spectroscopic techniques such as Laser Induced Breakdown Spectroscopy ...
A non-invasive study of the effect of three commercial cleaning products on shellac-coated mahogany
(Elsevier, 2023-02-01)
The Royal Palace of Norway has a large 19th century wooden furniture collection and most of it is coated with
shellac-based varnishes. Since these objects are part of the royal collections, they are still in daily use at ...
A Non-Invasive In Situ Spectroscopic Analysis of Cinnabar Minerals to Assist Provenance Studies of Archaeological Pigments
(MDPI, 2023-01-23)
This study presents a non-invasive in situ methodology based on the use of portable elemental (energy dispersive X-ray fluorescence spectroscopy, EDXRF) and molecular (Raman spectroscopy) spectroscopic-based instrumentation ...
Study Of The Soluble Salts Formation In A Recently Restored House Of Pompeii By In-Situ Raman Spectroscopy
(Nature Publishing Group, 2018-01-25)
The walls and mural paintings of Pompeii exposed directly to the rainfalls are the most impacted in view of the observed decay. However, there are also wall paintings in protected rooms showing evidences of decaying. The ...
Multianalytical Approach to explain the darkening process of hematite pigment in paintings from ancient Pompeii after accelerated weathering experiments
(Royal Society of Chemistry, 2013-10-17)
[EN] In this paper, recently excavated fresco painting fragments from the House of Marcus Lucretius (Pompeii) and not exposed to the atmosphere since the eruption of the Mount Vesuvius were subjected to a controlled SO2 ...
In situ non-invasive multianalytical methodology to characterize mosaic tesserae from the House of Gilded Cupids, Pompeii
(Springer, 2019-12)
Mosaics, one of the most important decorative artworks in the Roman culture, were usually elaborated with a set of tesserae joined with lime or others binders to form geometric or figurative decorations. The identification ...
Raman imaging to quantify the thermal transformation degree of Pompeian yellow ochre caused by the 79 AD Mount Vesuvius eruption
(Springer, 2019-11-07)
Most of the wall paintings from Pompeii are decorated with red and yellow colors but the thermal impact of 79 AD MountVesuvius eruption promoted the partial transformation of some yellow-painted areas into red. The aim of ...
Secco painting technique revealed in non-restored Pompeian murals by analytical and imaging techniques
(Elsevier, 2023-09-15)
The fresco technique appears to have been widely used on Roman mural paintings. The close observation of many of such murals suggests, however, the application of a secco technique over the fresco background. In this work, ...
Multispectroscopic and Isotopic Ratio Analysis To Characterize the Inorganic Binder Used on Pompeian Pink and Purple Lake Pigments
(ACS Publications, 2016-05-18)
Because of the fact that pigments are not ubiquitous in the archeological record, the application of noninvasive analytical methods is a necessity. In this work, pink and purple lake pigments recovered from the excavations ...
