“…It has been recognized that O 2 interacting with the interface can induce volume change, defect, and significant misfit at the interface, leading to marked stress at the interface and crack initiation. − This is against the interfacial adhesion and causes the failure of functional materials . From Section , O 2 interacting with the interface deteriorates the interfacial structures and reduces the interface strength.…”

The properties of the Cu/SiO 2 interface usually deteriorate in the complex atmospheric environment, which may limit its performance and application in the engineering. Using the reactive molecular dynamics method, we investigate how the mechanical behaviors of the Cu/SiO 2 interface change as it interacts with oxygen impurities. The interfacial oxidation degree could be enhanced as O 2 penetrates into the interface area. This makes the interfacial structure disordered and is not conducive to the survival of Cu−O−Si bondings, which reduces the tensile and shear strengths of the interface. To improve the abrupt bonding property change at the interface and modify the interfacial adhesion properties, O impurities are introduced at the Cu interstitial sites near the interface. By doing so, the interface strength can be significantly enhanced due to the production of typical O−Cu−O bondings while the regular interfacial structure is retained. Meanwhile, the interfacial oxidation also changes the tensile failure site and shearing sliding mode of the interface, i.e., from inside the oxide to between oxide and Cu. The findings of this work may not only advance the understanding of interaction mechanism between oxygen impurities and the Cu/SiO 2 interface but also provide new insights into optimizing the bonding properties of the metal/oxide interface.

Zirconia ceramics, as a category of metal oxide ceramics, stand out due to their impressive physicochemical and mechanical properties. Recognized for being bioinert, these ceramics are non-toxic, exhibit excellent biocompatibility, and offer superior mechanical strength. Moreover, zirconia’s natural aesthetic qualities enable it to closely mimic the appearance of natural teeth, making it an optimal choice for dental restorations, such as crowns, bridges, and veneers. This review examines the complex relationship between zirconia’s microstructure, including aspects like grain size, porosity, and phase composition, and how these factors impact its translucency and mechanical durability. A specific focus is on the critical role of the tetragonal phase in zirconia, spotlighting its contribution to the material’s superior mechanical strength and esthetic qualities. The stabilization of this phase, primarily through the use of yttria, is discussed for its dual influence on enhancing both the material’s strength and esthetic properties. Challenges such as low-temperature degradation (LTD) and discoloration are highlighted, along with potential solutions like advanced surface modifications and novel manufacturing techniques. The potential of flash sintering and 3D printing to further improve zirconia’s properties is also explored.
