However, achieving both a high separation efficiency and solvent stability is challenging, as it requires the critical and precise tuning of the film microporosity and internal molecular interactions. Here, we present a molecular linkage engineering approach to designing high-microporosity and structurally rigid poly(β-ketoenamine) membranes. By integrating a 3D shape-persistent triptycene scaffold (2,6,14-triaminotriptycene, TAT) and a hydroxyl-pendant trialdehyde linker (1,3,5-triformylphloroglucinol, Tp), the resultant TAT-Tp membranes exhibit an extraordinary surface area of 620.2 m2 g-1, far exceeding those of traditional polyamide and polyimine counterparts. The high density of β-ketoenamine linkages promotes the creation of intra- and intermolecular hydrogen-bonding networks, thereby imparting remarkable structural stability and inducing ordered local regions. These improved structural attributes, coupled with high microporosity, endow these membranes with dual-function superiority: 99.1% desalination efficiency and 99.2% methyl orange rejection in methanol. Furthermore, the membranes exhibit a remarkable solvent resistance, retaining structural integrity after 30-day exposure to diverse solvents. Experiments and simulations reveal the critical role of substantially interconnected ultramicroporous voids within the rigid crosslinked networks in achieving this superior performance. This work provides a framework for engineering resilient poly(β-ketoenamine) TFC membranes for high-efficient multitasking fluid separations.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"19 5","pages":"94908385-94908385"},"PeriodicalIF":0.0,"publicationDate":"2025-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/NR.2026.94908385.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147919200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these issues simultaneously, a novel an ion-selective, solvation-regulating, and flexible sulfonic acid-based water reducer gel electrolyte (PAM-FDN-CCS/ZSO) is designed in this work. This electrolyte features a 3D porous structure and abundant polar groups enabling efficient Zn2+ transport and solvation structure regulation, promoting uniform zinc deposition and suppressing water-related side reactions (e.g., hydrogen evolution) at the anode. Crucially, the strongly negatively charged sulfonic acid groups impart exceptional ion selectivity: they electrostatically repel polyiodide anion, effectively blocking their shuttle to the anode and minimizing active iodine loss, while permitting unimpeded Zn2+ diffusion. Consequently, Zn-I2 full cells employing this multifunctional gel electrolyte achieve outstanding cycling stability, retaining 118.5 mAh g-1 after 9,000 cycles at 5 A g-1.

Here, we have shown the enhancement of the activity and stability of Ru doped on a binary Ni-Mo2N support with 3D filamentous network structure (Ru/Ni-Mo2N) for OER. X-ray photoelectron spectroscopy (XPS) reveals the increase of the electron density around Ru sites by the interaction with Ni-Mo2N. Density functional theory (DFT) calculations confirm that this interaction induces a downshift of the d-band center of Ru sites, leading to optimized adsorption energies of intermediates on Ru and enhanced OER performance. Moreover, the sacrificial behavior of Ni effectively mitigates Ru over-oxidation and dissolution, thereby enhancing OER stability. Also, the 3D filamentous network structure with abundant pores is favorable to accelerate the transfer of electrolyte. As a result, the Ru/Ni-Mo2N requires an overpotential of 251 mV to achieve 20 mA cm-2, being 83 mV lower than that of Ru-Mo2N. An anion exchange membrane water electrolyzer (AEMWE) (Pt/C||Ru/Ni-Mo2N) delivers a voltage of 1.78 V at 500 mA cm-2, superior to that of the Pt/C||RuO2 (1.97 V @ 500 mA cm-2), and exhibits stable operation for over 500 h.

The POCs possess flexible framework and their bulks stay intrinsically in glassy state with well-defined transition temperatures (Tgs) and they can be attenuated from 61 to - 50 °C with glass-to-rubber transition upon the increasing of hydration levels. Two-level relaxation dynamics can be probed and the temperature dependence of their relaxation time differentiates them as cooperative backbone dynamics (α) and local groups dynamics (β). The dynamical transition of α relaxation is consistent with Tg in hydration dependence. Suggested from MD simulation, water binds to the surface amine groups of POCs and accelerate its local dynamics, leading to the activated backbone dynamics for the broadly tunable visco-elasticity and thermal hysteresis for anti-freeze property. In small-angle X-ray scattering studies, the physical denaturation of POC can be observed as collapsed molecular framework and altered solubility when heated above their Tgs in salt solutions.

To overcome these interconnected resistance mechanisms, we developed a multifunctional nanogel (3-in-1 NG) consisting of Fe2+-crosslinked boronate-conjugated mannose-alginate with encapsulated D-α-tocopheryl polyethylene glycol succinate (TPGS), which enables efficient tumor delivery. 3-in-1 NG achieved a 52.9% tumor growth inhibition rate and significantly impeded metastatic progression in 4T1 models. Mechanistically, the pH-triggered mannose release led to intracellular accumulation of mannose-6-phosphate. This effectively blocked glycolytic activity and reversed immunosuppressive lactate accumulation, priming tumors for ferroptosis. The nanoplatform simultaneously executes therapeutic functions including metabolic disruption via mannose-mediated glycolysis inhibition, TPGS-induced immunogenic cell death triggering dendritic cell maturation and cytotoxic T-cell infiltration, and Fe2+-dependent lipid peroxidation initiating ferroptosis cascade. These synergistic mechanisms established self-reinforcing therapeutic actions where metabolic inhibition enhanced both immune recognition and ferroptosis susceptibility, creating a feed-forward cycle that progressively dismantled tumor defenses.

However, rapid charge recombination and sluggish CO2 reduction kinetics still severely restrict the photocatalytic CO2 conversion efficiency. Herein, we fabricated a two-dimensional face-contact TiO2/Ag/CTF-Nv Z-scheme heterojunction featuring abundant N vacancies through a simple electrostatic self-assembly and annealing process for substantially enhancing CO2 photoreduction activity and selectivity. Specifically, in the absence of sacrificial reagent and photosensitizer, the TiO2/Ag/CTF-Nv achieves nearly 100% CO selectivity with a record evolution rate of 74.98 μmol g-1 h-1, surpassing that of TiO2 and CTF-Nv by approximately 12.4 and 4.8 times, respectively. Systematic investigations involving operando experiments and theoretical calculations clearly demonstrate that N vacancies with strong electron-trapping characteristics can accelerate Z-scheme charge transfer by directing electron migration from TiO2 to CTF-Nv, further increasing the charge separation efficiency. Moreover, the N vacancies with high electron density serve as active sites to promote interfacial electrons transfer to CO2, improve CO2 chemisorption/activation capacity, and decrease energy barrier for CO evolution. This work offers novel insight into the construction of defect-modulated Z-scheme heterojunction for significantly improving photocatalytic CO2 reduction performances.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"19 3","pages":"94908330-94908330"},"PeriodicalIF":0.0,"publicationDate":"2025-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147914277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
