Summary: The yellow coloring of large Buddhist paintings during the late Joseon dynasty was analyzed using Raman spectroscopy and non-invasive component analysis. p-XRF analysis confirmed the use of gold, orpiment, and organic pigments, but not the yellow chromophoric elements of the organic pigments. Microscopic analysis revealed no particles or crystals, and the identification of light elements or organic compounds via p-XRF was challenging. Raman spectroscopy detected gamboge in the presumed organic pigments, either alone or mixed with white inorganic pigments.

Summary: In Roman wall paintings, blue and green pigments were less commonly used compared to red and yellow due to their higher cost. The nomenclature and composition of these pigments, such as Egyptian blue for blue and celadonite, glauconite for green, sometimes lead to confusion. This study evaluates the Raman spectroscopic identification of Roman blue and green pigments used in wall paintings, aiming to clarify their nomenclature.

Summary: A photoactivatable Raman probe, 9-cyano-10-telluriumpyronin (9CN-TeP), was developed, which shows enhanced stimulated Raman scattering (SRS) intensity through photooxidation of the tellurium atom. By modifying the oxidation product to increase stability, a julolidine-like derivative, 9CN-diMeJTeP, was obtained with stronger SRS intensity and a bathochromic shift of the absorption spectrum.

Summary: The study of ancient Egyptian paintings started in the 19th century with the development of Egyptology. By the 1930s, extensive research had been conducted on the materials and techniques used. However, most of these studies were done in museums, with limited understanding of the actual painted surfaces. To address this gap, an interdisciplinary project employed portable analysis tools to study the physical composition of the paintings on-site, providing a stronger foundation for scientific hypotheses and a deeper understanding of ancient Egyptian art.

Summary: A new biopigment based on carminic acid was discovered in the red crown feathers of the Ruby-crowned Kinglet, analyzed using surface-enhanced Raman scattering (SERS). SERS proved to be extremely sensitive and non-destructive for identifying different feather biopigments, even in trace quantities and in the presence of other predominant coloring substances.

Summary: This study analyzed the ingestion of microplastics by zooplankton from two bays in the Mexican central Pacific. The results showed that certain zooplankton groups consumed microplastics, and omnivorous species were more likely to ingest them. However, the ingestion of microplastics cannot be attributed to a single factor, and variables such as sampling area, feeding strategy, size, and seasonality need to be considered.

Summary: This study evaluates the use of digital microscopic and in situ pXRF analyses for the characterization of paintings in the El Castillo cave, Spain. It finds that the compositional heterogeneity of the environment impacts the pXRF signals recorded on the paintings. The study concludes that a combination of in situ and laboratory invasive analyses is needed for the study of paint composition and technology, suggesting improvements for the reliability of pXRF results.

Summary: Since their introduction in the early 20th century, fluorescent pigments have been widely used in various fields. The Italian Black Light Art movement utilizes different types of radiation (UV or visible light) to convey different aesthetic messages. Through non-invasive in-situ investigation techniques, the researchers successfully identified the materials used by the artists in Black Light Art paintings exhibited in Milan.

Summary: Maya blue, a nanostructured hybrid organic-inorganic material, has been the subject of numerous studies since its discovery in 1931. It was used in mural paintings, manuscripts, and cultural artifacts in ancient Mesoamerica, as well as in syncretic art in early colonial New Spain. During the second half of the sixteenth century, local artists reintroduced Maya blue into their palette as a traditional technology.

Summary: In 1952, contemporary artist Federico Silva (Mexico City, 1923-2022) created the first outdoor mural painting titled "The technique at the service of peace." At the end of 2021, a project was initiated to study and conserve this mural. Through a multi-technique study, the conservation strategy was proposed to address the stability issues caused by the exposure of synthetic paints to the outdoor environment. Various examinations and analyses allowed for the characterization of materials used and the alterations in the color palette.

Summary: A controlled heating experiment was conducted on limestone samples from the Yucatan peninsula to establish a calibration curve for determining heating temperatures using FTIR-ATR ratios. This curve, the first in the Mayan area, is important for studying lime calcination technology used by the ancient Maya society. The model was then applied to an archaeological pit-kiln in the northern Maya lowlands, providing insights on lime manufacturing process and fire control in this culture.
