This study employed a green synthesis approach to produce zinc-silver bimetallic nanoparticles (Zn-Ag BMNPs) using the leaf extract of <i>Tinospora cordifolia</i> (TC). Characterization of the synthesized ZnNPs and Zn-Ag BMNPs revealed diverse structural and functional properties. FTIR analysis of these samples confirmed the anchoring of pytochmical groups on the surface of BMNPs, while XRD pattern revealed structural details with a crystallite size of approximately 19 nm. UV–Vis spectroscopy confirmed the formation of Zn-Ag BMNPs with absorption peaks in the range of 250–450 nm, and the optical energy gap was measured as 3.1 eV using Tauc plot analysis. Stability in aqueous suspensions was supported by zeta potential values of – 20.5 mV and – 22.7 mV, suggesting minimal aggregation. The potential antibacterial efficacy was assessed using disk diffusion and minimum inhibitory concentration (MIC) assays against <i>Escherichia coli</i> (<i>E. coli</i>). Zn-Ag BMNPs exhibited superior antimicrobial properties, achieving a maximum inhibition zone of 4 mm at optimal concentrations, while ZnNPs displayed comparatively weaker activity. These findings suggest that synthesized Zn-Ag BMNPs nanocomposites may have significant senergetic effect in treating chronic diseases and addressing the aforementioned issues.</p></div>","PeriodicalId":473,"journal":{"name":"Applied Physics A","volume":"131 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00339-025-08289-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143110217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of Fe₂O₃ on the physical, structural, and elastic characteristics of synthesized glass samples has been studied. The non-crystalline characteristics of the prepared glass samples were validated through XRD analysis, while their structural properties were examined using FTIR spectroscopy. Elastic properties were investigated through the measurement of longitudinal and shear ultrasonic velocities, employing the pulse-echo technique. The observed density and computed molar volume were determined to be influenced by the content of Fe₂O₃. The ultrasonic velocities, elastic moduli, micro-hardness, and Debye temperature exhibited similar behavior across all glass compositions, showing an increase with increasing Fe₂O₃ content. The findings are analyzed concerning the alteration in the topology of the borate network. The incorporation of Fe₂O₃ led to the transformation of BO₃ structural groups into BO₄ structural groups, enhancing the network connectivity and increasing the rigidity of the glass structure and elastic moduli. A variety of compositional parameters, including the average separation between boron ions, mean atomic volume, glass packing density, dissociation energy per unit volume, and excess molar volume, were assessed in concerning Fe₂O₃ content. These parameters were then correlated with the elastic properties, drawing on established models and theories within the discipline.
