Summary: The mineralogical analysis of archaeological pottery sherds from the Kundureddiyur archaeological site in Tamil Nadu, India revealed the presence of quartz, calcite, kaolinite, magnetite, and hematite minerals. XRD and FTIR characterization studies provided insights into the firing conditions and temperatures reached during manufacturing, with all samples fired below 900°C. EDS analysis confirmed the firing temperature by identifying major elements in the pottery samples.

Summary: The method of melting-quenching was used to manufacture glasses for this study, aiming to understand the structural, thermal, and crystallization features of the glasses. Various analytical methods, including X-ray diffraction and Fourier transform infrared, were utilized to examine the glasses' characteristics. The research found that the thermal stability of the glasses improved with an increase in Y2O3 concentration, and the modifier Y2O3 has a significant effect on the glass system.

Summary: In this study, the structural, thermal, and hydrogen adsorption properties of natural analcime-rich zeolite tuff and its acid-treated forms were investigated. The results showed that the acid-treated analcime zeolites had higher micropore volume, micropore area, and specific surface area, as well as higher H2 adsorption capacity and thermal stability. The hydrogen adsorption capacity of the analcime samples had an almost linear connection to the BET surface areas.

Summary: The assessment of compatibility between magnesium orotate and various excipients is an essential step in drug formulation and development. This study found that magnesium orotate had partial compatibility with corn starch, cellulose, and croscarmellose, while it showed the best stability when combined with polyvinyl-pyrrolidone. On the other hand, there might be an incompatibility between magnesium orotate and talcum. Based on the results, polyvinyl-pyrrolidone was identified as the optimal excipient for magnesium orotate.

Summary: Zinc (tris)-thiourea sulfate (ZTTS), a metal-organic crystal, was synthesized using the slow solvent evaporation technique. The as-synthesized ZTTS crystals were characterized using PXRD, FT-IR spectroscopy, UV-Vis spectroscopy, PL spectroscopy, SHG measurements, and thermal analysis. The results confirmed the orthorhombic structure, functional groups, transparency over the UV-visible spectral region, and potential applications as a nonlinear optical substance of the ZTTS crystals.

Summary: In this study, the thermal behavior of Estonian graptolite-argillite samples was investigated, revealing the complex mechanism of their thermal decomposition. The samples were found to have high proportions of orthoclase and quartz, and lower proportions of muscovite, jarosite, and pyrite. The thermal decomposition of the samples occurred in multiple steps.

Summary: In this study, magnetic Ni-Mn mixed oxides based on nanoparticles were synthesized using different methods, and characterized using multiple techniques. It was found that the glycine-assisted auto combustion method and the ceramic method led to the formation of different crystal phases, ultimately resulting in NiMn2O4 nanoparticles with ferromagnetic properties.

Summary: Chitosan, a naturally occurring polysaccharide, can form complexes with metallophthalocyanines such as copper(II)-(CuPc) and cobalt(II)-(CoPc) tetrasulphophthalocyanines. The study investigated the thermal stability of chitosan and its complexes with phthalocyanines in oxidizing and inert atmospheres, revealing different reaction pathways and product formations. Metallophthalocyanines were found to enhance the antioxidant properties of chitosan, increasing the temperature at which glycosidic bond cleavage reaction begins.

Summary: This study successfully characterized historical illuminated and rubricated manuscripts printed in the territory of the Grand Duchy of Lithuania using a variety of analysis methods. The manuscripts were found to contain cinnabar and red lead red pigments, as well as fish glue, parchment glue, and gum Arabic binding media. The purity of the red pigments in the manuscripts was notable, and the binding media could be easily identified using FTIR spectra. TG analysis revealed shifts in the temperature range of the original samples, demonstrating the importance of multiple analysis methods in characterizing cultural heritage materials.

Summary: Thermal analysis techniques such as TG, DTA and X-ray thermodiffraction are used in this study to evaluate and characterize pigments and supports of wall paintings from the San Isidoro del Campo Monastery in the 15th century. The different colors of the wall paintings are identified, along with the technology and raw materials used in their manufacture. The paintings were made using the fresco technique on support mortars made of calcite, quartz, and straw.

Summary: Synthetic plastics have become hazardous wastes, posing a threat to environmental health, so alternatives are needed. This study aimed to prepare corn starch-based bioplastics using fish scales as an alternative to synthetic plastics. Different bioplastic films containing various percentages of fish scale powder and corn starch were prepared and analyzed for their properties. The mixture of fish scale powder and corn starch powder in the ratio of 1:3 yielded the best results, making it a viable alternative to synthetic plastics.
