New acetylene line list near 3.8-µm - Part I

Two acetylene spectra were recorded between 2350 and 2750 cm−1 with Fourier Transform Spectrometer (FTS) using high optical path length. 14 bands were observed for the first time including one cold band. The positions and the intensities of the lines have been measured for 824 transitions of the 12C2H2 isotopologue. The band centers, the band strengths, the upper level spectroscopic constants and the Herman-Wallis parameters were retrieved for all bands...

Des outils de métallurgistes dans le Bronze ancien de Bretagne ?

La question de l'émergence et du développement des métallurgies du cuivre et du bronze constitue un enjeu majeur pour aborder les dynamiques culturelles et économiques de la fin du Néolithique et du début de l'âge du Bronze dans l'Ouest de l'Europe...

The interaction of sediments with the archeological iron remains...

Cultural heritage often brings to mind elements like sculptures, paintings, monuments, and buildings as well as archeological objects. Today, underwater heritage and its surrounding environment are also considered part of cultural heritage because communities identify themselves with the natural landscape...

First identification of sudoite in Caribbean Ceramic-Age lapidary craftsmanship

Lapidary craftsmanship was an important part of the material culture of Amerindians in the Antilles during the Early Ceramic period (400 BCE to 400 CE). Exhaustive analysis of archaeological beads and pendants from the French islands of the Lesser Antilles has revealed a green lapidary material used for the production of nine artifacts from five archaeological sites: sudoite. This di-trioctahedral member of the chlorite group has the relatively simple chemical formula of Mg2Al3Si3AlO10(OH)8...

Early anthropogenic use of hematite on Aurignacian ivory...

The Aurignacian (ca. 43–35 ka) of southwestern Germany is well known for yielding some of the oldest artifacts related to symbolic behaviors, including examples of figurative art, musical instruments, and personal ornaments. Another aspect of these behaviors is the presence of numerous pieces of iron oxide (ocher); however, these are comparatively understudied, likely owing to the lack of painted artifacts from this region and time period. Several Aurignacian-aged carved ivory personal ornaments from the sites of Hohle Fels and Vogelherd contain traces of what appear to be red ocher residues.

Spectral characterisation of a traditional Mesoamerican dye...

Characterisation of vegetal colourants in manuscripts is still a challenging task. Their identification using non-invasive techniques - since sampling is rarely possible - is valid only if there is evidence that the recorded signals are generated by compounds specific to the plant species. Otherwise, more extensive chemical characterisations are required to relate the non-invasive technique signals to the chemical composition of the dye extract and thus avoid misidentification...

On-site contactless surface analysis of Modern paintings from Galleria Nazionale (Rome)...

Seven artworks representing the diversity of paints used around the 1960s and created by German and Italian painters (J. Albers, A. Bonalumi, L. Boille, T. Scialoja and M. Schifano) were studied on-site at the Galleria Nazionale d'Arte Moderna (Rome) with mobile instruments. We present a methodology based on Specular Reflectance Infrared Spectroscopy (SR-FTIR) adapted to unvarnished paintings. Complementary measurements have been performed by Raman spectroscopy...

ATR-FTIR pre-screening analyses for determining radiocarbon datable bone samples from the Kings' Valley, Egypt

The tomb KV 40 in the Kings' Valley (Luxor, Egypt) has revealed mummified and highly fragmented remains of 83 adults, children, new-borns and infants, some of whom were, according to inscriptions, 18th dynasty king's sons or daughters (∼1370 BCE). This tomb was then secondarily reused by priestly families during the 22nd to early 25th dynasty (∼900-700 BCE). Radiocarbon dating of such bone remains would allow the evaluation of the ratio of burials by period and the identification of those from the 18th dynasty...
