Among the methods for AgNP synthesis, green synthesis using plant extracts is of particular interest because of its stability, sustainability, strongbiological activity, safety and environmental friendliness. This work presented the novel data on synthesis of the AgNPs using the <em>Smilax glabra</em> Roxb root extract. The fabricated AgNPs were characterized using scanning electron microscopy, X-ray diffraction, energy diffractive spectroscopy, and fourier-transform infrared spectroscopy. The anti-bacterial activity against bacterial pathogens, including antibiotic susceptible and resistant <em>Staphylococcus aureus</em>, <em>Escherichia coli</em> and <em>Streptococcus mutans,</em> was examined using agar diffusion and spectrophotometric methods at A<sub>700</sub>. The local toxicity of AgNPs was evaluatedin rabbits. The results showed that AgNPs had uniform distribution and spherical shape with the particle size in ranging from 20 to 50 nm. The nanoparticles exhibited antibacterialactivity against all tested microorganisms, including <em>S</em>. <em>aureus</em> ATCC 25923 (antibiotic- susceptible strain), antibiotic-resistant <em>S. aureus</em> strains ATCC 29213, ATCC 12493, 252, <em>E. coli</em> 25922 and dental caries bacterium <em>S. mutans</em> GS-5. Remarkably, no local toxicity of AgNPs was detected in the tested rabbits. Thus, the obtained data support the applications of these AgNPs in practice, such as in oral health care or dermal products.</div></div>","PeriodicalId":397,"journal":{"name":"Nano-Structures & Nano-Objects","volume":"43 ","pages":"Article 101513"},"PeriodicalIF":5.45,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144548536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review presents a systematic analysis of magnetically coupled resonant WPT (MCR-WPT) technology specific to the IoT perception layer, focusing on developments in high-degree-of-freedom (High-DoF) and multi-pickup charging (MPC) systems. First, we elucidate the unique advantages of applying MCR-WPT within the perception layer of IoT and outline the basic theoretical principles of MCR-WPT. Then, various types of magnetic coupling mechanisms (MCM) in recently published articles are discussed and analyzed rigorously. In addition, we provide a comprehensive description of the system optimization strategies proposed to achieve better performance, categorize and compare the characteristics, and evaluate the effectiveness of various approaches. Finally, the challenges and future perspectives are proposed.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"223 ","pages":"Article 116013"},"PeriodicalIF":16.3,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144536097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
