The Cu/CFHN was manufactured via graft copolymerization of acrylic acid onto CMC, followed by the in situ synthesis of Fe₃O₄ nanoparticles and subsequent loading of copper ions. 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. The findings underscore the capability of Cu/CFHN as a resilient, durable, and adaptable catalyst for organic synthesis, with encouraging applications in pharmaceutical and industrial chemistry.</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":"2334 - 2350"},"PeriodicalIF":4.7,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143809168","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}

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/cm³) 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/mm² for pure CNF and 8.9 N/mm² 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}

Thermogravimetric analysis (TGA) revealed differences in decomposition temperatures and thermal stability while melt flow rate (MFR) testing optimized melt spinning parameters. Rheological measurements showed viscosity reductions of up to 90% after spinning, reflecting structural transformations such as chain alignment and scission, with implications for processing and yarn performance. Both TPU types were successfully processed into multifilament yarns under comparable spinning conditions, achieving process speeds of up to 2000 m/min.

The hydrogel structure of Lig-CS was developed through hydrogen bonding and further cross-linked with glutaraldehyde, creating a natural framework that acts as a stabilizing, reducing, and stabilizing agent for the incorporation of silver nanoparticles (Lig-CS/Ag NPs) under ultrasonic irradiation. Various advanced techniques, including UV–vis, FE-SEM, TEM, EDX, FT-IR, ICP-OES, TGA, and XRD confirmed the well synthesis of the Lig-CS/Ag NPs composite. TEM analysis indicated that the silver nanoparticles were spherical, uniformly distributed, and approximately 10–15 nm in size. Additionally, the catalytic efficiency of Lig-CS/Ag NPs was assessed in reducing nitroarenes to produce aniline derivatives. The nanocatalyst demonstrated excellent recyclability, retaining its activity after more than nine cycles with only a slight decrease in efficiency. In addition, the Lig-CS/Ag NPs nanocomposite was engaged in biological assays like study of antioxidant properties by DPPH mediated free radical scavenging test and treating the diarrhea in rats. These Lig-CS/Ag NPs nanocomposite exhibited a decrease in the inflammatory cells infiltration in both the colon and ileum. Moreover, they resulted in lower concentrations of TNF-α, IL-17A, IL-6, and IL-1β, while simultaneously increasing the levels of IL-10 and IL-4 in the colon tissues. Additionally, the nanoparticles promoted the propionate and acetate production, modulated the composition and diversity of gut microbiota, enhanced the relative abundance of Bacteroides and Lactobacillus, and reduced the Coprococcus and Blautia relative abundance. The data reported that Lig-CS/Ag NPs nanocomposite may significantly improve the restoration of intestinal architecture in rats, reduce the levels of inflammatory cytokines, increase concentrations of SCFAs, aid in the recovery of intestinal mucosal barrier and the gut microbiota, and alleviate antibiotic-associated negative efficacies, including diarrhea and microbiota dysbiosis. Our investigation revealed that Lig-CS/Ag NPs nanocomposite has the potential to protect the intestinal barrier by enhancing the Claudin-1 and Occludin expression.

As a reaction, major companies in the food industry have committed to introduce more environmentally friendly packaging solutions. This research aimed to gather the reported packaging needs of some major Latin American food industries and propose a suitable bioplastic or natural polymer alternative to traditional plastics. Polyethylene Furanoate (Bio-PEF), derived from biomass, is highlighted as the most promising bioplastic. The study outlines a detailed production process for Bio-PEF from sucrose and ethylene, including four stages: obtention of 5-hydroxymethylfurfural, oxidation to furandicarboxylic acid (FDCA), production of ethylene glycol (EG), and polymerization of FDCA and EG. Braskem (Brazil), a pioneering and leading producer of bio-polyethylene (bio-PE), was identified as one of the most potential companies in Latin America to manufacture Bio-PEF. Although, the technology can be applied to any bioethanol company operating under a biorefinery scheme. In the Bio-PE process, Braskem uses sucrose from sugar cane to produce ethylene which could be subsequently used to synthesize Bio-PEF.
