Summary: The Cu-Te binary system, particularly the Cu2Te superionic conductor, has attracted significant interest in thermoelectric applications. Experimental and thermodynamic modeling techniques were used to investigate phase equilibria, with 16 crucial alloys analyzed to confirm phase relations including polymorphic transitions in Cu2Te, Cu4Te3 and CuTe. A thermodynamic optimization was conducted, resulting in a set of self-consistent thermodynamic parameters that align well with experimental data.

Summary: Thermodynamic properties of the Nd-Bi system were investigated using a combination of experimental measurements, first-principles calculations, data mining and machine learning predictions, and calculation of phase diagrams. New peritectic reaction and crystal structure of NdBi2 were confirmed, and a more complete phase diagram of the Nd-Bi system was calculated based on newly acquired experimental data and DFT-based calculations.

Summary: The thermodynamic properties and phase diagram data of the Sn-O system at 1 atm total pressure were evaluated and optimized to obtain a set of thermodynamic functions of stable phases. Discrepancies among experimental phase diagram data were resolved, and new experiments confirmed the high melting temperature of SnO2. A new phase diagram was constructed based on the optimized Gibbs energy functions of all phases.

Summary: In this study, CALPHAD thermodynamic models of the Ta-O system were developed using experimental data and first-principles calculations. The models accurately represent the equilibrium polymorphs of Ta2O5 and the O solubility in BCC Ta. Preliminary models for the liquid Ta-O phase were also developed. The calculated phase diagrams are consistent with existing experimental data.

Summary: The Bi-Te alloys were studied using various methods to determine phase diagrams, lattice parameters, and reactions. It was found that most compounds melt with decomposition reactions, except for Bi2Te3. EMF measurements were used to determine the partial molar functions of bismuth and standard thermodynamic functions of bismuth tellurides.

Summary: A thermodynamic description of the Ti-C-N-O quaternary system was achieved by evaluating the constituent ternary systems. These ternary systems were merged into a single database for predicting phase equilibria within the Ti-C-N-O quaternary system. Different phases were described using various thermodynamic models and the obtained model parameters reproduced the available phase diagram and thermodynamic data accurately.

Summary: This study investigates the interfacial reactions between Co and GeTe and determines the phase diagram of the Co-Ge-Te ternary system. It is found that Co reacts with GeTe to form multiple compounds at both 500 degrees C and 400 degrees C, with Co being the primary diffusion species in the Co/GeTe reaction couples. The results suggest that Co is not suitable as a barrier layer for GeTe at 500 degrees C.

Summary: This study investigated black tourmalines from granitic pegmatites in the Murzinka pluton, Russia. Various analytical techniques were employed to determine the tourmaline's composition, including electron microprobe analysis, LA-ICP-MS, Raman spectroscopy, and Mossbauer spectroscopy. The results showed the different types and compositional evolution of tourmaline, as well as the presence of different tourmaline groups based on trace and major element composition. The Fe3+/Fe2+ ratios in tourmalines from different host rock types indicated different oxidizing environments. The Raman data supported the composition of tourmalines.
