While lunar bases have been a focus of development in recent years, the complex and extreme environment of the lunar surface remains a considerable challenge for lunar exploration. Unlike those on Earth,lunar day and night temperature variations cause the properties of materials, especially metallic materials, to evolve in completely different manners. In this study, we investigated the property evolution of nine typical highperformance metallic materials using laboratory simulations of the extremely long-period lunar temperature environment. While lunation treatment improves the properties of all metallic materials, the microscopic mechanisms vary for amorphous and crystalline alloys with different structures. The treatment reduces both the loosely packed regions and heterogeneity in amorphous alloys while causing significant phase changes in crystalline alloys. Furthermore, a conservative prediction of the service life of metallic materials on lunar bases is provided based on analyzing microplastic events, followed by the practical material selection recommendations in various lunar application scenarios.

Microplastics(MPs) and cadmium(Cd) in soil have serious negative impacts on plant growth. As a bioremediator, Trichoderma viride may modulate the impacts of MPs and/or Cd on plant growth and heavy metal uptake. In this study, T. viride F7 was used to treat Cd-contaminated soil with and without the presence of polylactic acid MPs to investigate its effects on peanut growth, Cd uptake efficiency, and soil properties. Results showed that F7 increased soil pH,dissolved organic carbon, cation exchange capacity, microbial biomass nitrogen, and microbial biomass carbon, which resulted in increases of 2.10%–19.83% in peanut biomass and mitigated the negative effects of MPs and Cd on peanut growth. Trichoderma viride F7 reduced the soil bioavailable Cd and plant Cd concentrations by 16.68%–34.20% and 5.37%–25.84%, respectively. Regression path analysis showed that F7 could improve peanut performances by altering soil properties and reducing peanut Cd concentrations in MP-Cd-contaminated soil. Soil fungal community analysis indicated that the microbial community was altered via F7 inoculation, which antagonized Fusarium and promoted peanut growth. This study reveals the mechanisms of F7 in mitigating Cd contamination in the soil with the presence of MPs, which provides new ideas for managing MP-heavy metal-contaminated soil and improving soil health.
