This study investigates the green synthesis of calcium oxide (CaO) NPS derived from goose eggshells via thermal decomposition at 900 °C, and evaluates their efficacy in photocatalytic degradation and antibacterial applications. Comprehensive characterization using XRD, FTIR, FESEM, UV–Vis studies confirmed the successful formation of phase-pure, highly crystalline CaO NPS with an average particle size of 47.9 nm and a direct optical bandgap of 3.41 eV. The photocatalytic performance of the synthesized CaO Nanoparticles (NPs) was assessed through the degradation of Safranin dye (a model cationic dye) and the pharmaceutical compound Paracetamol under natural sunlight. The NPS achieved degradation efficiencies of 97.43 % for Safranin and 91.25 % for Paracetamol, following pseudo-first-order kinetics. The degradation rate constant for Safranin (2.896 × 10⁻² min⁻¹) was higher than that for Paracetamol (1.551 × 10⁻² min⁻¹), likely due to more favourable adsorption and stronger electrostatic interactions between the cationic dye molecules and the negatively charged CaO surface. In addition to their photocatalytic properties, the CaO NPS demonstrated significant antibacterial activity, particularly against Gram-positive <em>Staphylococcus aureus</em>, with a maximum zone of inhibition of 19.4 mm. The enhanced antibacterial performance is attributed to the nanoscale size, high surface reactivity, and the alkaline nature of CaO, which collectively disrupt bacterial membrane integrity. Overall, this work underscores the potential of bio-waste-derived CaO NPS as an environmentally sustainable, cost-effective, and multifunctional material for the dual purpose of wastewater remediation and microbial control.</div></div>","PeriodicalId":73541,"journal":{"name":"JCIS open","volume":"19 ","pages":"Article 100151"},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144913361","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 poses a significant global challenge of water scarcity. Hence, wastewater must be treated to reverse to useable water and prevent water scarcity. Failing to achieve this reversal increases ecotoxicological risks and human health. Textile wastewater contains harmful dyes. Photocatalytic degradation of these dye-contaminated wastewater is one of the major pathways in achieving reversal. However, this process is time-consuming, requires high-power lamps, and is expensive. Here, we report the effect of TiO₂ nanostructures prepared by facile hydrothermal synthesis on the dye degradation of one of the most common industrial textile dyes, methylene blue (MB), under natural sunlight. The impact of particle size on the photocatalytic activity and photocarrier migration rate was thoroughly examined. The size and surface morphology of the TiO₂ nanostructures depended on the concentration of the precursor during synthesis. Also, the effect of the pH of the dye solution on adsorption and photocatalytic degradation has been evaluated. With several optimized conditions, almost complete dye degradation was achieved within 40 min under the direct illumination of natural sunlight. The enhanced photocatalytic performance could correlate to the synergetic effect of a higher charge transfer mechanism, good catalytically active surface area availability (386 m²/g), and several optimized parameters that affect the reaction efficacy. Additionally, repeated use of NPs (five times) without sacrificing performance confirmed their stability and sustainability as a promising candidate for large-scale industrial textile wastewater remedies.</div></div>","PeriodicalId":73541,"journal":{"name":"JCIS open","volume":"19 ","pages":"Article 100150"},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144921838","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}

These nanofluids combine two kinds of nanostructures (single-wall and multi-wall) and have better energy conversion, cooling, and heat transmission qualities. Because of their tiny size and strength, carbon nanotubes (CNT) are used to increase machinery and components lubrication and boost system energy storage and charging cycle effectiveness of lithium-ion batteries. Therefore, a mathematical model is formulated to study the hydromagnetic CNT hybrid nanofluid mixed convective flow past an elongating porous surface in the occurrence of external heat source, thermal linear radiation, viscous and Joule dissipation. The nanoparticle diameter and interfacial layer effects are explored by incorporating the Gharesim dynamic viscosity model and Hamilton–Crosser thermal conductivity model.
