In this study, we report a novel and promising approach utilizing a cost-effective and simple chemical co-precipitation method for the synthesis of Cu₂O@Au nanocubes. The characterization of these nanocubes was conducted using various advanced techniques, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and photoluminescence (PL). These analyses revealed the formation of crystalline nanocube-structured catalyst, confirming their purity, chemical state, and electronic structure. The synthesized Cu₂O@Au nanocubes, particularly with 5 % Au over Cu₂O, showed the highest catalytic efficiency in degrading Rhodamine B (RhB), achieving about 99.6 % degradation in 7 min. The deposition of Au significantly enhanced the electron mobility, thereby increasing the catalytic efficiency of the catalyst. GC/MS analysis performed to identify the intermediates formed and a possible degradation pathway of RhB was proposed. In addition, the toxicity of intermediates also evaluated by ECOSAR software. Reusability tests were conducted to assess the consistency and practical application of Cu₂O@Au-5 % nanocubes. The results indicated high stability and sustained catalytic performance over multiple cycles. Additionally, the multifunctional properties of the synthesized material were validated through larvicidal activity tests, demonstrating its potential for broader environmental applications. Overall, Cu₂O@Au-5 % presents a highly efficient and versatile catalyst for environmental remediation and other practical applications, demonstrating significant potential for large-scale use. These findings underscore the promise of Cu₂O@Au as a multifunctional catalyst, capable of delivering substantial advancements in both environmental and - human health domains.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"43 ","pages":"Article e01185"},"PeriodicalIF":8.6,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142745985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reactive shell of DAS@HBPA/EP formed covalent bonds with protein molecules in SM, creating a highly interconnected structure that enhanced both the adhesive properties and water resistance of SM.

However, the current design practices are not remanufacturing-inclusive, i.e., the majority of products are designed for a single life cycle. As a result, potential products that can sustain multiple life cycles are deprived of additional benefits of being designed for remanufacturing, such as reduced material usage, lower cost, and improved environmental impact. Moreover, the uncertainty in design, material selection, and economics are not considered to produce remanufacturable designs. Accordingly, this research proposes a design for remanufacturing (DfRem) framework that accounts for design uncertainty and material price volatility. The framework systematically explores the design space, performs design optimization under uncertainty, followed by topology optimization to provide additional mass savings, and finally, a price volatility analysis for plausible design material choices. The candidate designs are evaluated based on their design mass, material price volatility, failure mode characteristics, carbon footprint, and embodied energy impacts. The proposed framework's utility is demonstrated via the use of an engine cylinder head case study subjected to thermo-mechanical loads along with fatigue and wear failure. Considering grey cast iron and aluminum alloy as the design material choices, it was found that the cast iron design reduced the initial design mass by 6% as opposed to a 5% decrease for aluminum. On the other hand, about 8% area of the cast iron design failed due to fatigue, compared to 3% for aluminum.
