Summary: The in-situ synchrotron high-energy X-ray study reveals that the canning-compressed BMG (CC-BMG) sample exhibits better tensile ductility and higher ultimate strength compared to the as-cast BMG sample. The CC-BMG undergoes two stages of plastic deformation, while the as-cast BMG only undergoes one stage. The structural crossover phenomenon occurs during the plastic deformation of CC-BMG.

Summary: We conducted a detailed study on the short- and medium-range order of glassy KSb5S8, a potential phase change material, using experimental and simulation techniques. The study involved diffraction techniques, EXAFS, and reverse Monte Carlo simulation to obtain accurate structural data and generate structural models. Density functional theory was also employed to investigate the structure and vibrational modes of selected clusters in the glassy structure. The findings revealed the coordination of Sb-S, the distribution of bridging S atoms, and the identification of a specific Raman mode associated with hypervalent bonding in the glass structure.

Summary: This study demonstrates that short-range ordering can tune the optical absorption edge in the long-range disordered alloy system (ZnSnN2)1-x(ZnO)2x at x=0.25. Using combinatorial cosputtering, a set of thin-film samples spanning this alloy space is synthesized. X-ray diffraction confirms the synthesis of a mixed-anion and -cation alloy. X-ray absorption analysis and spectroscopic ellipsometry reveal that local ordering increases the absorption edge energy at constant composition. This work opens up possibilities for property tuning with short-range ordering in (ZnSnN2)1-x(ZnO)2x and similar materials.

Summary: In crystals, lattice defects, such as dislocations, control mechanical deformation. Similarly, it is widely believed that even in glasses and liquids some kinds of defects, strongly disordered regions, play a major role in deformation. Recent results raise questions about the assumption that short-range order (SRO) in the nearest-neighbor cage of atoms determines defects in glasses and liquids.

Summary: The conventional wisdom about liquids is that they are completely disordered, but recent observations have shown that liquids have a surprisingly rich microstructure. This microstructure plays a critical role in various physical, biological, and industrial processes. By using advanced imaging techniques and a four-point correlation function, researchers have discovered that bidisperse colloidal liquids have a highly nontrivial structure comprising alternating layers with icosahedral and dodecahedral order. This intermediate-range order is strongly correlated with dynamical heterogeneities and relaxation dynamics in glassy liquids.

Summary: This study investigated the structural evolution of a Zr20Nb20Cu20Ni20Ti20 quinary high-entropy metallic glass (HE-MG) as a function of temperature and found that the high-entropy effect plays a crucial role in HE-MGs. The high-entropy effect leads to high variability in the chemical short-range order (CSRO), offering a potential avenue for effectively tuning structures and tailoring properties for various applications.

Summary: This study examined glasses with approximate compositions of GeTe4-Ag using multiple experimental techniques. By employing simulation techniques, the chemical correlations were determined. The results showed that Ge atoms were mainly fourfold coordinated, while Te atoms were predominantly twofold coordinated. Additionally, the addition of Ag did not alter the topology of the GeTe4 host network, and neighboring GeTe4 tetrahedra continued to predominantly exhibit corner sharing configuration.

Summary: Short range order and topology of GexS100-x glasses with a composition range of 20 <= x <= 42 at% were investigated using neutron diffraction, X-ray diffraction, and Ge K-edge extended X-ray absorption fine structure (EXAFS) measurements. The experimental data sets were analyzed using the reverse Monte Carlo simulation method. It was observed that both Ge and S atoms in the glasses satisfied the Mott-rule, with Ge and S atoms having 4 and 2 neighbors, respectively. The chemically ordered network model described the structure of these glasses, with Ge-S bonds being preferred and S-S bonds only present in S-rich glasses. Ge-Ge bonds were found to be necessary in Ge-rich glasses, and the connections between Ge atoms, such as edge-sharing GeS4/2 tetrahedra, were analyzed. The frequency of primitive rings was also calculated.

Summary: Through the use of DSC, SEM, TEM, and XRD, we have discovered hierarchical transformations during the crystallization of Mg66Zn29Ca5 metallic glass ribbons. The activation energies for the crystallization process were calculated using different thermodynamic models. Our findings indicate the formation of short-range order patterns in Mg66Zn29Ca5 metallic glass and the impact of heating rate on crystallization and growth process. The phase transformations during annealing were also studied, revealing the formation and consumption of various metastable phases.

Summary: This paper investigates the biological degradation of a tricalcium aluminate (C(3)A) phase treated with reactive media from the agricultural industry. The phase composition and microstructure of the samples were characterized using various techniques. The results showed that the phase composition of the synthetic tricalcium aluminate preparations changed depending on the corrosion exposure conditions. The main crystalline phases formed were catoite and hydrocalumite, along with secondary crystallisation of calcium carbonates. The presence of aluminium hydroxides was also observed. These findings contribute to the development of bio-corrosion-resistant cements for bioenergetics.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
