In this study, we develop a Cu-bearing stainless steel with excellent anti-pathogen property against influenza virus, which can distinctly reduce more than 95 % of viable influenza virus on its surface within 6 h.

To overcome these challenges, we present a novel approach that utilizes inductive heating to generate large-area single-crystal Cu(111) substrates, enhancing graphene growth. By applying a controlled thermal gradient to commercial polycrystalline copper foil, we induce the nucleation and growth of a single grain, a process facilitated by the controlled movement of induction coils. This method contrasts with traditional roll-to-roll (R2R) techniques, which require strict sealing, and enables the expansion of the single-crystal region over large areas. The resulting single-crystal substrates support the growth of high-quality graphene with highly aligned, defect-free domains, as confirmed by optical microscopy and Raman spectroscopy. This scalable and cost-effective technique offers a promising route for producing high-performance 2D materials with minimal defects, making it suitable for both research and industrial applications.</div></div>","PeriodicalId":384,"journal":{"name":"Materials Letters","volume":"386 ","pages":"Article 138234"},"PeriodicalIF":2.7,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143420393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
