The decoration of SiO₂ and Ag onto ZnO has upgraded surface area and improved charge separation efficiency by restricting electron-hole recombination, as verified by various characterization studies. The functionality, crystallite size, morphology, elemental constituency, band gap energy, recombination of photogenerated electrons and holes, degraded daughter fragments of dye, and surface area of the composite were all considered through characterization using FT-IR, XRD, FESEM, EDX, UV-DRS, PL, LCMS, and BET. To verify the photocatalytic activity, the effect of catalytic dosage, dye concentration, stirring speed, contact time, and pH was methodically assessed. The material afforded almost 98% photocatalytic degradation efficiency for MB dye and 97% for MG dye in its optimal condition. The kinetic study revealed that photocatalytic degradation follows a pseudo-first-order kinetic model and displays a single rate-determining step governed by reactive species. UV light at 243–286 nm and 315–400 nm wavelengths induces the MB and MG dye degradation, respectively. The framed dye degradation mechanism explains the complication of the internal charge carrier generation, such as electrons and holes, and also the formation of harmless ionic radicals. Furthermore, the reusability studies proved the regeneration of the photocatalyst closer to 64% for its activity until five successive cycles, showing its operational stability and potential applicability of the nanohybrid. Moreover, cost analysis declares it is cost-effective and has potential for further industrial applications.</p></div>","PeriodicalId":471,"journal":{"name":"Applied Nanoscience","volume":"16 6","pages":""},"PeriodicalIF":3.674,"publicationDate":"2026-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149338197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study indicates that the combination of titanium and coumarin showed a synergistic antibacterial effect, with a zone of inhibition measuring 23 mm against <i>E. coli</i> and 20 mm against <i>S. aureus.</i> Additionally, plate count assays demonstrated that TiO<sub>2</sub>/CU@CS nanoparticles can eliminate approximately 90% of bacterial colony-forming units from human pathogens at a maximum dose of 100 µg/mL. Notably, antifungal studies revealed significant colony reduction against infectious fungi such as <i>Aspergillus fumigatus</i> and <i>Candida albicans</i>. The cytotoxicity assay confirmed that the fabricated TiO<sub>2</sub>/CU@CS nanoparticles are non-toxic and suitable for biomedical applications. Wound healing studies suggested that the group treated with TiO<sub>2</sub>/CU@CS nanoparticles experienced the fastest cell movement and re-epithelialization process. The cationic groups in chitosan can adhere to bacterial cell walls through electrostatic interactions, effectively killing the bacterial cells. This mechanism enhances antibacterial efficacy and improves wound sterilisation. Overall, this study underscores the effectiveness of TiO<sub>2</sub>/CU@CS nanoparticles as an effective material for wound healing and antimicrobial applications. Therefore, these multifunctional composite nanoparticles, which exhibit synergistic antibacterial effects, could serve as a promising candidate for bacterial-infected wounds.</p></div>","PeriodicalId":471,"journal":{"name":"Applied Nanoscience","volume":"16 6","pages":""},"PeriodicalIF":3.674,"publicationDate":"2026-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149250698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, pristine calcium carbonate (CaCO<sub>3</sub>), sodium stearate-modified CaCO<sub>3</sub> (SS-CaCO<sub>3</sub>), and a mixture of SS-CaCO<sub>3</sub> with silica nanoparticles (SiO<sub>2</sub>NPs) improved the hydrophobicity of WBPU. Four formulations, namely, pristine WBPU (P1), WBPU+CaCO<sub>3</sub> (P2), WBPU + SS-CaCO<sub>3</sub> (P3), and P3 + SiO<sub>2</sub>NPs (P4), were prepared and applied onto mild steel substrates. The composite formation was confirmed using Fourier-transform infrared (FTIR) spectroscopy, with the intensity of the O-H band in P4 being lower. According to the X-ray diffraction (XRD) study, the dispersion of the SiO<sub>2</sub>NPs in P4 was improved, which reduced the crystallite size to 22.38 nm. The scanning electron microscope (SEM) images indicated that the surface roughness of P4 increased with the enrichment of SiO<sub>2</sub>NPs on the surface of the coating. The spectroscopic evidence of the energy-dispersive X-ray (EDX) spectroscopy revealed the corresponding elemental distribution and a higher proportion of oxygen. The measurements of water contact angle (WCA) showed that P4 had the best hydrophobicity (105.08 ± 0.74°), which can be explained by the fact that P4 possessed the best surface roughness produced by the nanoparticles.

Scanning electron microscopy confirms the microcrystalline morphology, while X-ray photoelectron spectroscopy excludes the presence of In–O bonds associated with In(OH)₃ impurities. Brunauer–Emmett–Teller analysis demonstrates meso-porosity with a pore size of 3.39 nm and a specific surface area of 45.59 m<sup>2</sup>/g.

Reactive oxygen species scavenging experiments further elucidate the degradation pathways: superoxide radical anions (O₂●⁻) dominate the rate-determining step in Sulforhodamine B degradation under halogen irradiation, whereas both O₂●⁻ and hydroxyl radicals (●OH) contribute significantly to Rhodamine B degradation under sunlight.

Nonetheless, the computational space of perovskites is quite large and first-principles is expensive, and this makes systematic optimization of materials a challenging problem. This paper presents a unified multiscale system that entails the implementation of density functional theory (DFT), machine learning (ML), and device-level simulation to hasten the search and development of high-performance perovskite solar cell materials. Physically significant descriptors are generated through DFT calculations such as structural parameters, electronic bandgaps, formation energies, and properties of defect-related characteristics. The descriptors are utilized to train the supervised ML models that can predict the important material and photovoltaic performance indicators with high accuracy at a rapid rate. Predictions of the ML are then combined with practicing simulations of the device to assess open-circuit voltage, short-circuit current density, fill factor, and power conversion efficiency. The findings show that there are good correlations among defect tolerance, bandgap optimization, and photovoltaic performance with defect suppression being a leading channel of increasing the efficiency. The current DFT-ML scheme consumes much less computational power; however, still has physical interpretability, and can offer efficient and predictive solution to perovskite material screening as well as solar cell design scaling.</p></div>","PeriodicalId":471,"journal":{"name":"Applied Nanoscience","volume":"16 4","pages":""},"PeriodicalIF":3.674,"publicationDate":"2026-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148750532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
