However, their performance is severely compromised by oxidative degradation under aerobic high-temperature conditions. In this work, we report a bifunctional crosslinking strategy to enhance the oxidative stability of polyethyleneimine (PEI)-impregnated adsorbents via functionalization with ethylene glycol diglycidyl ether (EGDE). The optimized 0.15EGDE/PEI@MX560 adsorbent exhibited superior thermal and oxidative stability, retaining 85 % of its initial CO₂ uptake after 3 h oxidation at 120 °C in real air, compared to <10 % for unmodified 50 %PEI@MX560 adsorbent. Moreover, it maintained over 70 % adsorption capacity after 50 consecutive adsorption-regeneration cycles under realistic regeneration conditions, demonstrating excellent cyclic durability. A series of complementary characterization techniques revealed that EGDE effectively converted primary amines to more stable secondary and tertiary amines, and constructed a crosslinked network through ring-opening reactions of epoxide groups. This network significantly suppressed polymer chain scission and the formation of oxidative degradation products such as NH₃, H₂O, and CO₂. This study highlights the mechanistic advantages of double-epoxide crosslinking to overcome the oxidative degradation of solid amine adsorbent, offering a practical pathway toward durable CO₂ capture materials for industrial flue gas applications.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"1 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145077430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, optimizing electrical performance while ensuring degradability remains challenging. By combining simulation and dynamic bonding design, this study tackles these issues effectively. Density functional theory (DFT) calculations reveal that the acetal structure possesses a wide band gap (E_g = 8.85 eV), which inhibits charge carrier migration in dynamic networks, thereby reducing dielectric loss. Utilizing this, we propose a “wide band gap + deep charge trap” strategy to design a degradable epoxy thermoset (SpQEA-MNA). Compared to conventional DGEBA-MNA, SpQEA-MNA exhibits superior dielectric properties: lower average negative charge density (−1.48 vs. −1.72C/m³), higher volume resistivity (5.64 × 10¹⁵ vs. 3.63 × 10¹⁵ Ω·cm), improved breakdown strength (36.4 vs 35.7 kV/mm), and a 29.8 % increase in flexural strength (125.7 vs 96.9 MPa). Furthermore, SpQEA-MNA demonstrates exceptional stability under hygrothermal aging, retaining 86.8 % of its initial breakdown strength. A composite incorporating hexagonal boron nitride (h-BN) achieved a further enhanced breakdown strength (42.4 kV/mm) while maintaining full recyclability, with 96.8 % filler recovery. The reclaimed filler retained 94.7 % of its original performance in new composites, while the recycled resin functioned as an effective toughening agent, increasing impact strength by 39 % at 1 wt%. This study establishes a novel framework for designing high-performance, degradable insulating materials with sustainable lifecycle utility in electrical applications.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"127 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145077432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Low-temperature rate performance at −20 °C and cycling at −10 °C further demonstrated the excellent adaptability of SA-containing electrolytes under sub-zero temperature. Moreover, under high-voltage operation at 4.0 V, the SA-containing electrolyte effectively suppressed capacity fading, resulting in an 11.44 % improvement in capacity retention. Compared to conventional commercial electrolytes, this electrolyte enables interfacial optimization by suppressing excessive growth of cathode and anode interphases, also it eliminates detrimental electrolyte components, tune the solvation structure and promote interfacial reaction kinetics. In situ gas analysis conducted during cycling at 45 °C revealed that SA significantly inhibits gas-evolving side reactions, thereby ensuring the safety of SIBs.

The pH-dependent coordination modes of TA-Fe(III) modulated shell thickness and the differential co-release behavior of CLO and TA, achieving synergistic regulation of the efficient accumulation of CLO and plant health. The synergistic release of TA promoted the targeted accumulation efficiency of CLO, achieving >90 % pest control efficacy for 14 days in hydroponic conditions. In addition, CLO@GR activated antioxidant enzymes and the ascorbate-glutathione cycle, significantly reducing reactive oxygen species (ROS) bursts caused by CLO accumulation, preserving chloroplast integrity.

Here, we developed a microsphere-based platform (GBKE) that transforms upon mild hydration into a dynamic, self-healing hydrogel, allowing in situ gelation and stable retention within soft tissues. The hydrogel forms a highly porous, interconnected network that facilitates nutrient transport and deep cellular infiltration. The microspheres form an interpenetrating network structure by co-assembling through β-sheet/π-π stacking driven self-assembly, combining gelatin methacrylamide (GelMA) with the self-assembling small molecule BPAA-GFF. The chondrogenic-inducing small molecule kartogenin is bound to the BPAA-GFF nanofiber network through non-covalent interactions such as hydrogen bonds and hydrophobic forces, achieving sustained inducing effect. The MSC affinity peptide E7 is covalently coupled to the surface of the microspheres to achieve targeted cell homing. Thanks to the enhanced effect of the nanofiber network induced by BPAA-GFF, the storage modulus (≈1700 Pa) and critical shear stress (≈35 Pa) of the microgels are significantly higher than those of pure GelMA microgel. In vivo, GBKE microgels significantly improved disc height index and extracellular matrix restoration in rat models, maintaining NP regeneration for at least 8 weeks. In rabbit models, MRI analyses and histological results confirmed durable structural and functional repair for up to 12 weeks. This system enables the programmed regulation of endogenous cell behavior, offering a promising approach for minimally invasive intervertebral disc repair.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"38 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145077437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MR performance was investigated in terms of hydrogen permeation, methane and carbon dioxide conversion, hydrogen recovery, and hydrogen yield with a temperature range of 500–600 °C and pressures between 1 and 5 bar. At 600 °C, the Pd/YSZ membrane demonstrated a hydrogen permeance of 1.8 × 10⁻⁶ mol·m⁻²·s⁻¹·Pa⁻¹ and an apparent activation energy of 11.9 kJ/mol. Increasing the temperature from 500 °C to 550 °C at 5 bar resulted in CH₄ and CO₂ conversions increasing by 26 % and 6 %, respectively, while hydrogen recovery and yield improved by 6 % and 24 %. Our results showed higher CH₄ conversion than other membrane reactors and conventional reactors under the same operating conditions.Experimental results indicate that methane decomposition occurs simultaneously with biogas reforming, contributing significantly to coke formation, particularly at elevated temperatures. Introducing small amounts of oxygen into the feed effectively reduced carbon deposition from 1.0 g to 0.65 g at 550 °C and 5 bar by oxidizing deposited carbon. However, this also led to a reduction in CO₂ conversion from 22 % to 6 %, due to the consumption of CO₂ during carbon oxidation reactions. Importantly, the addition of O₂ did not negatively impact membrane and catalyst activity, and hydrogen recovery and yield remained stable. Additionally, steam regeneration was shown to effectively remove carbon deposits from both the catalyst and membrane, while simultaneously generating hydrogen via gas–solid reactions. So far, no research study has evaluated the effect of steam for coke removal on Pd-based membrane reactors. The MR exhibited stable hydrogen permeation flux and maintained complete selectivity over 800 h of continuous operation. Up to now, no Pd-based membrane has been resisted for this period under dry reforming reaction. Thus, Pd-YSZ MR demonstrates strong long-term operational stability and viability for low-carbon hydrogen production from renewable biogas.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"69 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145077482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

EVs are naturally occurring nano-sized lipid bilayer vesicles produced from all cell types containing proteins, lipids, nucleic acids, and other metabolites, which play a significant part in the exchange of substances and the transmission of information between cells. Nevertheless, clinical applications of EVs-based therapies remain challenging due to limited yields, functional heterogeneity, and ineffective targeting.

Its extreme chemical stability renders conventional water treatment ineffective, particularly for trace-level contamination (μg/L). Rapid, efficient, and sustainable remediation strategy for such environmentally relevant PFOS concentrations remains a critical and underexplored challenge. To address this, a sustainable adsorbent was engineered from wheat straw biochar via H₂O-, HCl-, NaOH-modification and further calcination. Pretreatment with H₂O, HCl, or NaOH facilitated the elution of pore impurities, enhanced oxygen-containing functional groups, and promoted aromaticity; subsequent calcination further optimized pore structure, increased hydrophobicity, reduced band gap energy, and facilitated charge transfer. Among the synthesized adsorbents, NaOH-modified and calcined biochar (NBCC) demonstrated exceptional PFOS adsorption, achieving 90.2 % removal (initial PFOS concentration: 100 μg/L) at 0.10 g/L dose within 1 h equilibrium time and exhibiting a maximum capacity of 5.17 mg/g. Mechanistic studies identified hydrogen bonding, hydrophobic interactions, and pore filling as dominant pathways. Crucially, UV-driven photoregeneration effectively liberated active sites of PFOS-laden NBCC while concurrently degrading adsorbed PFOS, enabling efficient regeneration. NBCC retained 97.9 % adsorption efficiency over five consecutive adsorption-photoregeneration cycles, demonstrating exceptional reusability. This work pioneered an integrated “adsorb-degrade-reuse” approach advancing sustainable PFOS treatment beyond conventional and unsustainable “adsorb-and-dispose” paradigms. NBCC's high removal efficacy at environmentally relevant concentrations, coupled with scalable production and robust regenerability, positions it as a promising solution for global PFOS mitigation, with potential applicability to structurally analogous <em>per</em>- and polyfluoroalkyl substances.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"36 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145077434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MTAH evaporator demonstrated excellent evaporation performance with an evaporation rate as high as 3.09 kg m⁻² h⁻¹ and a photothermal conversion efficiency as high as 93.16 % under 1 solar light intensity. The self-growth property of TiO₂ on the MXene surface endowed the evaporator with the ability of photocatalytic degradation of pollutants. In addition, the incorporation of trace Ag nanoparticles played positive roles, which not only significantly enhanced the photothermal conversion performance of MXene, but also broadened the light response range of TiO₂ and effectively suppressed the complexation of photogenerated electron-hole pairs.
