Their excellent biocompatibility allows the avoidance of secondary surgeries for removal. However, magnesium-based biocompatible alloys are still suffering from some shortcomings such as rapid corrosion rate, causing limited service time. Among the factors that influence the corrosion resistance, the grain orientation (GO) is a primary factor influencing its corrosion behavior. Since the surface energy differs among various grains with different orientations, the corrosion sensitivity is anisotropic. Based on the 10T samples, we have established a functional relationship between the reciprocal of corrosion rate and the percentage of each grain orientation. The fitting parameters for the grain orientations of (0001), (1–100), and (11–20) are 0.133, 0.034, and −0.0287, respectively. This intuitively demonstrates that different grain orientations exhibit varying sensitivity to corrosion, with (0001) showing the highest corrosion resistance, while (11–20) has a negative impact on improving corrosion resistance. Furthermore, when we applied this formula to another set of 3T samples, we found that the calculated results matched well with the actual measurements, indicating that this formula has a certain degree of accuracy in quantifying the relationship between corrosion rate and grain orientation.</div><div>(3T and 10T represent for the annealing treatment made at 400 °C for 3 and 10 min respectively.)</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142432581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to various contaminants, antibiotics are specifically engineered for durability and efficacy in the system of the human body (human health). Although this design ensures their performance, it also results in their extended longevity and resilience against degradation in natural contexts. These challenges can be addressed by an advanced oxidation process (AOP) utilizing ternary heterojunction nano catalysts (NCs). In this study, the NCs were synthesized through a combination of calcinated-assisted reverse microemulsion and hydrothermal methods. The synthesized NCs were characterized by using various analytical techniques. The enhanced charge separation and migration in Zn₃V₂O₈/ZnO/NiCo₂S₄ (ZZN) NCs results in 97.3 % degradation of rifampicin (RIF) within 80 min. ZZN NCs exhibit superior catalytic performance under visible light irradiation compared to its pristine Zn₃V₂O₈, ZnO, NiCo₂S₄, and binary ZnO/NiCo₂S₄. The enhanced photocatalytic performance can be primarily attributed to the synergetic effects among Zn₃V₂O₈, ZnO, and NiCo₂S₄ facilitated by the cascade-driven charge transfer mechanism. The prominent reactive oxygen species that participated in photocatalytic degradation activity were found to be superoxide (O₂•^-) and hydroxide radicals (•OH) which were confirmed through ESR and quenching experiments. From the practical application perspective, ZZN NCs ternary heterostructure demonstrated excellent stability and durability after being recycled six times. This study serve as a vital reference for future investigation into the photocatalytic mechanism related to heterostructure NCs, highlighting their potential for eco-friendly methods to eliminate pollutants and paves a way for manufacturing innovation in near future.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142444637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
