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.

Summary: The relationship between the heterogeneous structure and structural relaxation in metallic glasses was explored by investigating the quasielastic and viscoelastic behavior of a Zr55Cu30Ni5Al10 metallic glass. Stress-annealing treatment was used to retain elastic strain energy, and a unique creep recovery phenomenon was observed during the reheating process. The Maxwell model was employed to qualitatively describe the mechanisms of elastic strain energy retention and release.
