The nanocomposite is synthesized through the insertion of metal oxide nanoparticles (NPs) into a hydrogel matrix, optimizing the material's photocatalytic properties. The successful synthesis of the hydrogel nanocomposite was verified using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). Through determination of XRD parameters, a successful synthesis of Co-CuO HNCs with an average crystallite size of 10.21 nm was confirmed. SEM images showed that after incorporating spherical-shaped Co-CuO NPs into the hydrogel matrix, the surface of the final composite became rough and fragmented with a surface area of 4.06 m<sup>2</sup>/g. Optical studies showed that the bandgap was reduced as Co-CuO NPs were incorporated into the hydrogel matrix. Photocatalytic degradation experiments were conducted using methylene blue (MB) to assess the hydrogel nanocomposite's efficiency. The results demonstrate a significant enhancement in degradation rates compared to traditional photocatalysts, due to the synergistic effects of the metal NPs and the hydrogel network. Within 120 min, the photocatalytic removal efficiency of MB reached 96% at a pH of 10 using 100 mg of the catalyst. The photocatalytic degradation process followed a pseudo first-order kinetics with a rate constant of 0.0183 min<sup>−1</sup>. Moreover, scavenger studies showed that ∙OH radicals were major species responsible for the photocatalytic degradation process. The study highlighted the potential of metal-based hydrogel nanocomposites as efficient and sustainable photocatalysts for environmental remediation, offering a promising solution for the treatment of dye-contaminated wastewater. Future research will focus on optimizing the performance of the nanocomposite and exploring its practical applications in large-scale water treatment processes.</p></div>","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":"33 5","pages":"2425 - 2442"},"PeriodicalIF":4.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10924-025-03533-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143809145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the potential of kaempferol-loaded zein nanoparticles (KZNPs) for this purpose. Kaempferol, a flavonoid with anticancer properties, has poor water solubility, limiting its effectiveness. Zein nanoparticles (ZNPs) offer a promising delivery system for such bioactive compounds. UV-Vis spectroscopy identified Kaempferol’s absorption peaks at 347 and 253 nm, which shifted to 338 nm when encapsulated in ZNPs, indicating a change in π–π* conjugation. Dynamic light scattering (DLS) and scanning electron microscopy (SEM) confirmed that sodium caseinate (SC) stabilizes ZNPs, resulting in spherical particles with optimal size and stability. Fourier transform infrared (FTIR) spectroscopy suggested enhanced hydrogen bonding between Kaempferol and zein. Differential scanning calorimetry (DSC) revealed the absence of Kaempferol’s crystalline peaks in KZNPs. The encapsulation efficiency (EE) was 98.39%, and drug release studies showed a controlled release of 79% kaempferol over 8 h.

The Cu/CFHN was thoroughly characterized using FT-IR, XRD, SEM, TEM, EDX, XRF, VSM, and TGA, validating its structural integrity, elevated porosity, magnetic properties, and substantial copper ion adsorption capacity(28.00 wt% Cu(II)), as well as thermal stability. The Cu/CFHN catalyst was assessed in the Huisgen 1,3-dipolar cycloaddition of terminal alkynes, alkyl halides, and sodium azide, producing 1,2,3-triazoles with remarkable efficiency (yields up to 95%) under mild reaction conditions (room temperature, 6 mol% catalyst loading). The reaction exhibited significant tolerance for various functional groups, smooth progression, and elevated product yields. Water was recognized as the ideal solvent, consistent with green chemistry principles. The catalyst demonstrated exceptional stability and recyclability, maintaining catalytic activity across five successive process cycles with minimal efficiency loss (less than 5% decrease in yield). This method emphasizes the ecological and financial benefits of employing Cu/CFHN, such as the incorporation of biodegradable and biocompatible materials, reduced waste production, and streamlined reaction processing.

Building on the established flame retardancy of citric acid-based nanocellulose, our study marks a significant advancement by employing a simple and efficient methodological approach. We introduce a simple and facile technique for crosslinking CNF aerogel using a single crosslinking agent for extraction and modification. The cross-linked CNF aerogel shows a 91% porosity with a low density (0.15 g/cm<sup>3</sup>) which is also positively influenced by the morphological studies. In addition, the inclusion of citric acid into CNF improves water stability, mechanical performance (7.8 N/mm<sup>2</sup> for pure CNF and 8.9 N/mm<sup>2</sup> for cross-linked CNF aerogels), and thermal stability, while reducing the residue of the cross-linked material to 1.6% from 6.4% of pure CNF aerogel. The cross-linking of aerogel by citric acid could enhance fire resistance by lowering the production of hazardous and combustible gases. Furthermore, the cross-linked CNF aerogel was evaluated with a thickness of 40 mm, as the pure CNF aerogel demonstrated optimal sound absorption behavior at this thickness according to simulations conducted using COMSOL Multiphysics software. This work contributes to the broader understanding of how nanocellulose can be engineered for structural building applications, paving the way for further innovations in environmentally friendly aerogel technologies.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":"33 5","pages":"2319 - 2333"},"PeriodicalIF":4.7,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143809164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In hygiene-critical sectors like medicine, the development of sustainable materials is imperative because of the predominant use of single use plastics. Polylactic acid (PLA) has emerged as a bio-based alternative for clinical applications because of its degradation profile. To further enhance antibacterial properties and sustainability performance, a novel biocomposite based on PLA with hemp hurd filled with silver nanoparticles (AgNP) was developed. Here we present a life cycle assessment (LCA) based on ISO 14040 and 14044 to evaluate the added value of the antibacterial biocomposite compared to conventional antibacterial materials from an environmental perspective. The environmental impacts are analyzed in comparison to virgin PLA, fossil-based polypropylene (PP) and high-density polyethylene (HDPE) combined in a disinfecting wipes and sterilized application. Our results show that the novel biocomposite has in general higher environmental impacts than its counterparts. Notably, our findings suggest a significant impact derived from high energy demand required for AgNP synthesis. To be able to compete with other materials, the energy demand needs to be minimized, which should be the focus of further research.</p></div>","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":"33 5","pages":"2300 - 2318"},"PeriodicalIF":4.7,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10924-025-03512-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143809346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
