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 polycrystalline ZrTe3O8:2%Er, 3%Mn material was prepared using solid-state reaction technique, and it exhibited a cubic phase structure with two types of polyhedrons. The Raman spectrum revealed the asymmetric stretching vibration of the Te-O-2-Zr bridges, and the magnetic results showed weak ferromagnetic behavior at low temperature. Additionally, the ZrTe3O8:2%Er, 3%Mn material showed significant emission in the visible and near-infrared range when excited at 490 nm, making it suitable for W-LED applications.

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: Pottery from the Neolithic and Bronze Ages in South Korea was analyzed for mineral composition, firing temperature, and color factors. Red pottery from the Neolithic Age was black in color, while that from the Bronze Age had a reddish yellow hue. The pottery was primarily composed of quartz and plagioclase, and the color factors for reddish yellow were hematite and maghemite, while black color was due to amorphous carbon and magnetite.

Summary: In this study, Raman spectroscopy and deep learning were combined for the first time to establish an accurate, simple, and fast method for identifying the origin of red wines. Raman spectra were collected from 200 red wine samples of Cabernet Sauvignon variety from four different origins using a portable spectrometer. Differences in the Raman spectra were found, primarily caused by ethanol, carboxylic acids, and polyphenols. The analysis showed that the performance of these substances on the Raman spectrum varied with the climate and geographical conditions of the origin. Four models, including ANN, MCNN, GoogLeNet, and ResNet, were used to establish red wine origin identification models based on the analyzed Raman spectra. The classification results showed that these models performed well, with MCNN achieving the best performance.

Summary: Crystalloid fluids have a greater impact on deoxygenation of red blood cells compared to blood plasma, as shown in Raman Tweezers spectroscopy analysis. Additionally, the ability of cells in blood plasma to withstand laser-induced deoxygenation is better than those in crystalloid fluids at higher laser powers. Principal component analysis of Raman spectral data effectively differentiates between cells in plasma and crystalloid fluids, demonstrating the effect of external induced stress on red blood cells.

Summary: This article introduces an innovative, label-free, noninvasive, and rapid Raman spectroscopy-based method for evaluating the quality of pRBCs. The method allows the evaluation of pRBC quality in a rapid and noninvasive manner, without unsealing the pRBCs bag, by collecting Raman spectra from the pRBCs supernatant mixture and conducting chemometric analysis. The spectroscopic data are compared with predefined reference values to assess their utility for transfusion to patients with AML and ALL.

Summary: Villa di Teodorico in Galeata is an important archaeological site in Italy, occupied from the 6th century BC to the 12th century AD. The most interesting findings are related to the Roman and late antique periods, with the construction of a large villa and the palace of the Ostrogothic king Theodoric in the area. A multi-technique approach was used to analyze Roman wall paintings fragments and late antique glass sectilia fragments, providing essential archaeological, historical, and technological information. The evolution of manufacturing technologies and trade routes during the late antique period were revealed by changes in raw materials.

Summary: This study investigates the structural properties of geopolymers made from locally available volcanic feedstocks for the development of sustainable non-structural building materials. Geopolymer binders and mortars based on volcanic pyroclastic residues from Mt. Etna were examined to assess their response to natural weathering. The results show that volcanic ash-based geopolymers have a better resistance to weathering in the hot summer Mediterranean climate zone compared to ghiara-based products.

Summary: The viability of portable Raman spectroscopy as a nondestructive and noninvasive method for identifying gemstones on Hellenistic-Roman glyptics was assessed in situ at the Regional Archaeological Museum Paolo Orsi in Syracuse, Italy. The study confirmed most of the identifications and found that the glyptics were mainly made of chalcedony, with other materials including garnet, glass, and amber. The noninvasive investigation allowed for both quick identifications and more detailed studies on chalcedonies and garnets with minimal interference with the museum's activities.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
