Nanoparticles (CFO) were first synthesized using the self-combustion sol-gel method, and then their surface was coated using silica and the Stöber sol-gel method. The resulting nanoparticles and nanocomposites were characterized using XRD, FESEM, TEM, AFM, FTIR, BET, BJH, and VSM analyses. The results showed that increasing the TEOS concentration resulted in a thicker silica shell, which increased the dispersion, improved the stability, and prevented the aggregation of the nanocomposite (CFO@Si) compared to the nanoparticles (CFO). It was also found that the magnetic properties of the nanocomposite (CFO@Si) decreased with increasing thickness of the silica shell compared to the nanoparticles (CFO). Consequently, this paper highlights the critical role of TEOS concentration and silica shell thickness in improving the physical and magnetic properties of the nanocomposite (CFO@Si) compared to the nanoparticles (CFO).

To address this gap, our current study focuses on the synthesis of hybrid materials based on a partial exfoliation of graphite and its oxidized analog, employing a novel method in which the ultrasound (US) forces applied are enhanced by the incorporation of lignin, further promoting the exfoliation. During the synthesis process, graphite layers are separated, and lignin particles are intercalated between these layers, promoting exfoliation. In this study, we incorporated two types of lignin, namely Kraft lignin (KL) and organosolv lignin (OL), and characterized the resulting materials using physicochemical (FTIR, Raman, EA, XRD, and XPS), morphological (AFM, and SEM), and electrochemical (CV and EIS) techniques. The physicochemical and morphological analyses provided substantial evidence supporting the exfoliating capacity of lignins and their deposition on the partially exfoliated surface. Interestingly, the effectiveness of lignins was found to be more pronounced in the case of oxidized graphite (GO) as compared to non-oxidized graphite. This observation was further corroborated by improved electrochemical performances, evidencing the deposition of lignin particles and the exfoliation as positive contributions to enhanced capacity values.</div></div>","PeriodicalId":17219,"journal":{"name":"Journal of Science: Advanced Materials and Devices","volume":"10 2","pages":"Article 100887"},"PeriodicalIF":6.7,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This international emphasis on green nanotechnology research has caused the development of various nanomaterials that are suitable for physiologically and environmentally responsible applications. Here, gold nanoparticles were formulated utilizing the leaf of <em>Lawsonia inermis</em> for making the synergistic anti-gastric cancer and antioxidant effects. According to the antioxidant assay, the nanoparticles and BHT (butylated hydroxytoluene) respective IC₅₀ values for 2,2-Diphenyl-1-picrylhydrazyl (DPPH) were 32 and 10 μg/mL. The characterization of the nanoparticles was conducted through various chemical techniques, including Fourier transform-infrared spectroscopy (FT-IR) and ultraviolet–visible spectrophotometry (UV–Vis), zeta potential, and transmission electron microscopy (TEM). The data suggested that the green-synthesized nanoparticles had an average size of 29.66 nm.

This study investigates the mechanical performance of soft, multilayered ceramics, focusing on how hexagonal tile size, adhesive interlayer thickness, and layer configuration influence flexural compliance, penetration resistance, and energy absorption. Using a precision digital laser manufacturing platform, industrial-grade alumina ceramic sheets were laser-cut into 2.5 mm and 5 mm hexagonal tiles, then laminated with adhesive layers to fabricate soft ceramic beams. Experimental results from 4-point bending and penetration tests reveal that smaller tile sizes and thinner adhesive layers enhance flexural compliance, achieving up to a 35 % improvement in flexibility compared to larger tiles and thicker adhesives. Conversely, larger tiles and thicker adhesives improve penetration resistance by up to 28 %, offering superior protection against localized impacts. Configurations featuring larger tiles and thicker adhesive layers also achieved a 42 % increase in energy absorption, demonstrating their ability to store more energy under localized forces. Failure modes varied across configurations, with smaller tiles predominantly exhibiting tilting failure while larger tiles fractured more uniformly under penetration loading. Compared to traditional ceramic armor and bioinspired nacre-like materials, the developed soft ceramics exhibit significantly higher weight-specific compliance while maintaining competitive penetration resistance and energy absorption.
