Summary: In this study, 0-3 piezoelectric ceramic-Portland cement composites with different compositions were fabricated and investigated. The addition of epoxy resin resulted in increased density and acoustic impedance, as well as decreased porosity and dielectric constant. The piezoelectric charge coefficient decreased with increasing epoxy resin content, while the piezoelectric voltage coefficient showed a notable increase up to 3%. The optimization results showed that the BZT50ER3 composite had the best acoustic impedance and piezoelectric voltage coefficient, while the BZT60ER7 composite had the highest planar and thickness electromechanical coupling factors.

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.
