Summary: The signature of oxygen ion conductivity in hydro-thermally synthesized Ce(1-x)LaxO(2-delta)(0 ≤ x ≤ 0.50) solid-electrolyte samples has been investigated. The temperature-dependent softening of oxygen defect mode in Raman spectroscopy and broadening of a feature related to oxygen defects in optical absorption spectroscopy can be efficient tools to probe the signature of oxygen ion conductivity.

Summary: In this study, single crystalline samples of Ag7+x(P1-xGex)S-6 (x = 0, 0.1, 0.25, 0.33, 0.5, 0.75, 1) solid solutions were investigated. The optical parameters and structural parameters of the solid solutions were analyzed, and it was found that increasing the Ge content can decrease the pseudo-gap energy and Urbach energy of the materials. This suggests that the single crystalline Ag7+x(P1-xGex)S-6 has potential applications in solar harvesting.

Summary: The electrical and dielectric properties of ternary glasses in the Sb2O3-PbCl2-AgCl system were investigated across a broad temperature and frequency range. The study found that the DC conductivity significantly increases with increasing AgCl or PbCl2 content, and the activation energy of the conduction process decreases with the substitution of PbCl2 by AgCl. The influence of composition on the AC conductivity of the glasses was also discussed.

Summary: A series of glasses in the ZnO-MoO3-TeO2 system were synthesized and investigated for their thermal, optical, structural, and electrical properties. Substitution of TeO2 for ZnO and/or MoO3 resulted in structural transformation and decomposition of the tellurite network. The major charge transport mechanism in these glasses is the polaronic process through the tellurite glass network. Molybdenum oxide positively affects the electrical conductivity of the glasses, while Zn2+ ions limit free electron transport. These glasses with wide optical transmittance and relatively high electrical conductivity may find application in optoelectronic devices.

Summary: Thin film polyethylene oxide, produced by the thermal evaporation technique, exhibits structural and property differences compared to bulk polyethylene oxide. The dielectric constant of polyethylene oxide thin film is 10 times greater than that of bulk polyethylene oxide. There is consistency among dielectric constants, activation energies, and free volume fractions for both thin film and bulk samples. Polyethylene oxide thin film is observed to be more brittle than bulk polyethylene oxide.

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.
