Utilizing cold coprecipitation and one-pot hydrothermal methods, a range of CeO₂ and highly efficient photocatalytic AgI/CeO₂ composites were successfully prepared. These composites were, for the first time, applied to bamboo scrimber for antimicrobial research, significantly enhancing its antibacterial properties. Advanced characterization techniques such as XRD, SEM, TEM, and FT-IR were employed to analyze the prepared materials’ structural characteristics systematically. Under visible light irradiation, the photocatalytic activity of AgI/CeO₂ composite catalysts with varying AgI loadings was evaluated using levofloxacin (LVF) as a model pollutant. The results indicated that the 20%AgI/CeO₂ composite exhibited a unique mesoporous structure, high-specific surface area, and optimal photocatalytic degradation efficiency for LVF, achieving a degradation rate of up to 94.06%. Additionally, this composite significantly bolstered the antibacterial efficacy of the bamboo scriber under visible light conditions. It was securely anchored onto the surface of the bamboo scriber through a specific surface treatment process, forming a durable and practical antibacterial protective layer. In conclusion, AgI/CeO₂ composites demonstrate exceptional performance in both photocatalytic degradation and bamboo scrimber modification, making significant contributions to environmental protection and the development of green building materials.\u0000</p></div>","PeriodicalId":592,"journal":{"name":"International Journal of Mechanical and Materials Engineering","volume":"20 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://jmsg.springeropen.com/counter/pdf/10.1186/s40712-025-00273-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This degradation impacts critical properties like impact resistance, tensile strength, and thermal stability, limiting ABS’s usability in manufacturing. This study explores advanced techniques for restoring aged ABS, including physical methods like reprocessing and thermal treatments, chemical restoration using solvents and additives, and mechanical enhancement through fibre or filler reinforcement. Each technique extends the lifespan of ABS materials, aligning with sustainable practices and the circular economy by reducing raw material consumption and minimising waste, enabling its reuse in industrial applications. Case studies on successful additive integration demonstrate the recycling process yielding 20% and 59% enhanced tensile and impact strength, improving material performance and durability after restoration. It was observed that the chain extenders in rABS boost the tensile and impact strength to 34.7 MPa and 6.3 kJ/m<sup>2</sup> from 20 MPa and 2.1 kJ/m<sup>2</sup> in aged ABS (almost 90% and 30% boost compared to virgin ABS). Studies also reflect that the effect of UV exposure reduces the impact and tensile strength by 50% and 25% after 6 and 12 months respectively. Stabilisers and plasticisers are observed to increase the service life and flexibility by 25% and 20% respectively in rABS. These findings demonstrate the significance of using mechanical and chemical stabilisers and mechanical reinforcement in ABS.

This approach offered a new avenue for further research in the field and significant potential for clinical application.</p></div>","PeriodicalId":592,"journal":{"name":"International Journal of Mechanical and Materials Engineering","volume":"20 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://jmsg.springeropen.com/counter/pdf/10.1186/s40712-025-00263-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
