Summary: Accurate microchemical characterisation was performed on a collection of glass samples found in the archaeological excavation of Jesolo. The research aimed to improve the knowledge of early medieval glass and identified the glass as soda-lime-silica glass made of impure sands and natron. Iron and manganese were found to be the main elements responsible for the glass coloration.

Summary: In this study, chemical analysis was performed on 48 glass samples from Thessaloniki, Greece, revealing that most of the glasses originated from Egypt and were produced using natron as a flux. MnO was the main decolorizer, with some samples also containing Sb2O3. The presence of recycling processes was also evident.

Summary: The study investigates the previously overlooked influence of glass contact-induced changes in surface composition of Pt, PtIr and Ir protective coatings on glass adhesion. It shows that an increase in Pt concentration leads to an increase in macroscopic glass adhesion, while IrO2 can inhibit glass adhesion.

Summary: This study focuses on the color variations and frosted appearance of Chinese blue-and-white porcelain produced in folk kilns and recovered in underwater archaeological contexts. The results suggest that these variations are mainly attributed to the production process, composition, and firing conditions of the ware, as well as the switch from foreign to domestic pigment sources during the late Ming period.

Summary: In this study, the investigation of 38 late antique vessels from the archaeological excavation of Salapia was conducted using EMPA and LA-ICP-MS. The majority of these vessels were made of 'fresh' glass, using impure sands and mineral soda. The use of colorants was rare, with most decolored glass obtained by adding manganese. The prevalence of Egyptian-HIMT glass over the Levantine was observed in terms of provenance.

Summary: The study in Eastern Romania investigated Phaeozems with deep mollic topsoil and cambic B horizon, suggesting that prehistoric human habitation and climate changes during the Holocene played a role in their development. Soil samples from an Eneolithic settlement were analyzed, showing differences in elemental contents above and below the dwelling remnants, indicating two major phases in the evolution of these soils. Results also suggest that climate and land use changes since the mid-Holocene controlled the formation of the overthickened soils.

Summary: According to the Scopus database, there have been 91 scientific papers published in indexed journals in the domain of environmental science and agricultural science over the last five years that discuss the use of pXRF (portable X-ray fluorescence) technique. This indicates an increasing application of this technique in scientific research. The aim of this research was to analyze the metal content in commercial mineral nitrogen fertilizers using the pXRF method. The results showed that complex fertilizers had higher amounts of certain metals compared to single-component fertilizers, and the pXRF method was more suitable for the detection and quantification of metals in complex fertilizers.

Summary: The composition of natural saliva is highly variable and unstable outside the oral cavity, leading to the use of artificial saliva solutions in corrosion testing. This study investigates the corrosion behavior of a CuZn37 alloy exposed to different saliva solutions with varying compositions. The results show that the corrosion rate of the alloy is influenced by the different saliva solutions, and the presence of organic compounds may limit the formation of a protective surface film.

Summary: Since the 1960s, infrared reflectography has been used to visualize ancient paintings' underdrawings, and several successful scanning techniques and devices have been proposed. Scanning is necessary due to the small size of the sensors, typically ranging from 0.1 to 0.3 megapixels. Point, line, and image scanners are all viable options for obtaining high-resolution infrared images of the painting.

Summary: This study investigates the differences between bare carbon dots (CDs) and nitrogen-doped CDs synthesized from citric acid as a precursor, aiming to understand the mechanisms of emission and the role of the doping atoms in shaping the optical properties. It is found that nitrogen doping causes a decrease in the relative content of O-containing functional groups and the formation of N-related molecular and surface centers that enhance the quantum yield of the material.

Summary: The "Ladies of Art" exhibition held in Milan's Palazzo Reale in 2021 focused on the history of women artists in the 16th and 17th centuries. In collaboration with multiple research institutions, diagnostic analyses were conducted on two paintings by Giovanna Garzoni from the 17th century Savoy Court. Non-invasive techniques such as high-resolution multiband imaging, hyperspectral imaging, and X-ray fluorescence were used to map and distinguish the pigments and underdrawing of the paintings. This research provides new insights into the meticulous painting technique of Garzoni and contributes to a better understanding of her artistic production.

Summary: For the first time, a dispersive micro-solid phase extraction (D-mu SPE) based on graphene oxide was used for the ultrasensitive determination of Cd. With this method, Cd can be efficiently extracted from a mixture of alkali and alkaline earth metals without the need for an elution step. The combination of D-mu SPE and SAGD OES significantly reduces matrix effects and improves the tolerance of Cd to alkali metals. The method shows simplicity in the measurement system and the commercially available nanosorbent used.

Summary: This work proposes a rapid and sensitive spectroscopic method for detecting melamine in food products using rare-earth Terbium-doped Graphene Quantum Dots (Tb-GQDs) synthesized by microwave and simple chemical conjugation methods. The synthesized Tb-GQDs show a spherical shape with a size of approximately 6 nm and a quantum yield of 52%. The maximum detection limit for melamine concentration in milk and milk products is found to be 0.31 μM. The dual emitting Tb-GQDs provide a sensitive and effective platform for real-time detection of melamine in food samples, particularly in milk, and show promising potential in the food industry.
