The present study employs a more environmentally friendly, gentle, and energy-efficient approach to effectively separate and recycle waste polyester/cotton blended fabrics. Firstly, the waste polyester/cotton blended fabrics are swollen using acetic acid to increase the gaps of the polyester molecular chain to facilitate contact between the polyester and the depolymerization solvent. Then, the polyester of the polyester/cotton blended fabrics was efficient degraded by ethanolamine and the regenerated cotton fibers were separated after simple filtration. The effects of pretreatment condition, depolymerization temperature and time on the depolymerization efficiency of polyester under atmospheric pressure and catalyst-free conditions were investigated, and the regenerated cotton were characterized and compared with virgin cotton. Considering the comprehensive energy consumption and other factors, the optimal swelling conditions were 40 °C for 50 min. The optimal depolymerization conditions were 80 °C for 3 h, and the depolymerization rate of polyester reached 96.00 %. The chemical structure and crystal structure of regenerated cotton is comparable to that of virgin cotton, and the tensile properties are weakened by about 0.67 N. Polyester depolymerization product bis(2-hydroxyethyl)terephthalamide (BHETA) can be used as a precursor for foams and adhesives. The “polyester dissolution for cotton retention” technology enables high-added-value utilization of waste polyester/cotton blended fabrics. The wide application of this technology is of great significance to the economy, ecological and environmental protection.</div></div>","PeriodicalId":22138,"journal":{"name":"Sustainable Chemistry and Pharmacy","volume":"45 ","pages":"Article 102011"},"PeriodicalIF":5.5,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The DICP device, equipped with 1 × 3 cm CEO-impregnated cellulose paper (CP) strips (prepared via a simple dip-coating process), is attached to a 1000 μL micropipette. The findings from density functional theory (DFT) study reveals that CEO-impregnated cellulose demonstrates stronger and more diverse interactions with anesthetic drugs, as evidenced by more negative adsorption energy (−0.62 eV) and enhanced non-covalent interactions compared to cellulose alone.

The adoption of geopolymers as a substitute for ordinal Portland cement facilitates the recycling of industrial solid waste. The high brittleness of geopolymers poses a significant limitation to their applications. Incorporating fibers is a common method for enhancing toughness and improving crack resistance of geopolymers. Research on fiber-reinforced geopolymer composites (FRGC) has achieved notable advancements in frost resistance. However, comprehensive summaries on the frost resistance of FRGC remain limited. In this work, the specific effects of steel fiber, polymer fiber, hybrid fiber and other fiber on mass loss, compressive strength loss, flexural strength loss, ultrasonic pulse velocity, and relative dynamic elastic modulus of geopolymers after freezing-thawing (F-T) cycles are briefly reviewed. The effect of fiber content, fiber type, and fiber size on frost resistance index was compared. Different fibers have different effects on geopolymers frost resistance indexes under different F-T cycles. Within a specific fiber content range, fibers positively influence the frost resistance of geopolymers. The uniform distribution of fibers is the key to improving the frost resistance of FRGC. The formation and growth of cracks are influenced by the bridging effect of fibers, which limits the penetration of free water and enhances frost resistance. Furthermore, this study utilizes VOSviewer software for visual analysis of the literature, identifying key factors influencing frost resistance and revealing trends and hotspots in the research field.

In this study a zero-waste fractionation approach was developed to enhance protein recovery from whole and dehulled hempseeds. Following oil extraction, protein recovery was evaluated under various solubilization pH values (10, 11 and 12). Results showed that the recovery of protein isolates was significantly improved at high solubilization pH. Specifically, the highest protein recovery (22.23 g) and purity (94.5 % Kjeldahl protein) were obtained from dehulled hempseeds at pH 12. Amino acid profiles of protein isolates were similar; however, FTIR analysis revealed differences in the secondary structures of whole and dehulled protein isolates, with dehulled isolates exhibiting lower α-helix and higher β-sheet contents. Similarly, the physical properties of whole and dehulled protein isolates differed, with the latter exhibiting lower solubility and higher oil holding capacity and foaming stability. In addition, to fully utilize hempseeds, a zero-waste approach was developed by producing photoluminescent carbon dots from residual solids. Ultimately, this study is the first to propose an integrated processing concept that not only maximizes hempseed protein recovery yields but also incorporates a sustainable valorization strategy for residual solids, offering a promising approach toward the establishment of sustainable agri-food systems.</div></div>","PeriodicalId":22138,"journal":{"name":"Sustainable Chemistry and Pharmacy","volume":"45 ","pages":"Article 102005"},"PeriodicalIF":5.5,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143685112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
