In this study, a high-load zeolite/plant fiber composite was successfully fabricated based on the coordination interaction between aluminum ions and carboxyl groups. The bamboo fibers (BF) undergo controlled TEMPO-mediated oxidation modification, followed by the in situ generation of NaA zeolites through hydrothermal crystallization. This result confirmed that the zeolite content of the NaA/BF achieved a maximum value of 63.9%, while exhibiting a specific surface area of 431.5 m 2 /g. The modified composite (NaA/BF@Co) was subsequently synthesized through a sol-gel impregnation process utilizing cobalt chloride aqueous solution. Then the NaA/BF@Co paper exhibited a remarkably high hydroscopic responsiveness, undergoing a pronounced chromatic transition within seconds when exposed to controlled environmental conditions at 50% relative humidity (RH). Graphical The bamboo fiber (BF) was subjected to TEMPO-mediated oxidation, and then it was mixed with the NaAlO 2 solution and NaOH solution. Subsequently, Na 2 SiO 3 9H 2 0 solution was added, and a high-load zeolite/bamboo fiber composite (NaA/BF) was obtained through hydrothermal synthesis. The NaA/BF was immersed in a cobalt chloride solution to obtain the NaA/BF@Co. The NaA/BF@Co paper was prepared by the sheet former and exhibited high water sensitivity.

Choline chloride, p-toluenesulfonic acid, benzoic acid, and oxalic acid-based solvents can be used for recycling solid electrolytes in all-solid-state lithium batteries (ASSLBs); however, they are not naturally available and have relatively low biocompatibility. By contrast, glucose-based low-melting mixture solvents (LoMMSs) stand out as green solvents with advantages including low cost, biodegradability, high biocompatibility, and high natural availability. In this work, GLU-based LoMMSs as green solvents for the recovery of solid electrolytes in ASSLBs are employed. First, leaching factors—including molar ratio, temperature, time, and liquid-to-solid ratio—are comprehensively investigated, resulting in maximum leaching efficiencies of Li and Al of 78.2% and 97.0%, respectively, achieved at 80 °C over a duration of 24 h with a liquid-to-solid ratio of 200. Then, the pH values, infrared spectra, and combustion behaviors of the LoMMSs and leachate are compared. Third, scalability tests are conducted to assess the feasibility of large-scale application. More importantly, an antisolvent-responsive strategy is introduced to precipitate multiple metals from the leachates, and a linear relationship is identified between the polarity of the antisolvents and their precipitation efficiency. Graphical Glucose-based low-melting mixture solvents are proposed as green solvents with high biocompatibility and high natural accessibility for the recovery of solid electrolyte from all-solid-state lithium batteries.

Porous carbon materials have been considered as one of the most suitable candidate cathodes for the aqueous supercapacitors due to their wide sources, low cost, high structure stability, and surface area. The doping strategy is always used to enhance their electrochemical energy storage performances. Previous works focus on the effective treatment of different carbon precursors to promote their electrochemical properties but little works pay attention to the modification of commercial activated carbon (AC). Herein, a simple and facile way to prepare nitrogen, oxygen co-doping activated carbon (N, O-AC-2) with porous structure has been proposed and developed via one-step pyrolysis. With the more doping content, especially oxygen content with abundant C═O functional groups, the N, O-AC-2 for the supercapacitors exhibits high specific capacitance and excellent rate performance. Furthermore, N, O-AC-2 electrode for the zinc ion hybrid capacitor also shows good electrochemical performance in terms of high capacitance, rate capability, and cycle stability with a high capacity retention. Thus, this one-step co-doping strategy of modifying the AC is promising to provide information for the doping modification and synthesis of porous carbon and facilitate the development of good-performance porous carbon electrode materials. Graphical By heat treatment with the addition of KOH and urea, a nitrogen and oxygen co-doping strategy for modifying commercial porous activated carbon is proposed to achieve excellent electrochemical performance. The effect of KOH and urea on the structural and electrochemical performance is further investigated.

Aqueous zinc-ion batteries (AZIBs) have recently emerged as a promising candidate for large-scale energy storage applications, primarily due to their nonflammable nature, low production costs, and satisfactory specific energy. Nevertheless, their cycle stability is significantly limited by the inevitable formation of Zn dendrites and undesirable water-induced parasitic reactions. To tackle these challenges, a porous poly(p-aminoazobenzene) (PPAAB) interfacial protective layer is developed for regulating the transport and deposition behavior of Zn 2+ ions. The engineered PPAAB coating, functionalized with polar moieties ( NH and N ), exhibits strong hydrophilic characteristics that enable controlled Zn 2+ ion flux and deposition behavior via a selective ion-confinement mechanism. Consequently, the Zn@PPAAB anode exhibits improved interfacial dynamics and a low nucleation overpotential, demonstrating stable plating/stripping behavior. When paired with a NaV 3 O 8 (NVO) cathode, the NVO||PPAAB@Zn cell showcases impressive capacity retention, maintaining 84% of its capacity after 1100 cycles at 1.0 A g −1 . This study not only advances accessible interface engineering but also provides deeper mechanistic insights into Zn anode behavior, paving the way for enhanced AZIBs. Graphical A porous poly(p-aminoazobenzene) (PPAAB) protective layer functionalized with polar groups ( NH and N ) is engineered to regulate Zn 2+ flux, suppress dendrite growth, and inhibit side reactions, achieving highly stable and reversible zinc metal anodes for advanced aqueous batteries.

Enantioselective sensing of 3,4-dihydroxyphenylalanine (DOPA) enantiomers is highly significant in biology and pharmaceutics, yet developing sensors with high enantioselectivity and analyte-specific output signals remains challenging. In this study, we constructed an L-cysteine (Cys)-Fe 2+ nanozyme through self-assembly of L-Cys and Fe 2+ . This nanozyme exhibited efficient peroxidase-like activity, with a K cat value of 2.1 × 10 −9 M·s −1 ·µg −1 toward 3,3“,5,5”-tetramethylbenzidine (TMB). When using D/L-DOPA as a substrate, we observed higher catalytic efficiency for L-DOPA than for D-DOPA, with a selectivity factor of 1.6. Mechanistic studies revealed that this enantioselectivity originates from the preferential adsorption of D-DOPA over L-DOPA on the nanozyme surface, which impedes the oxidation kinetics by blocking substrate access to the active sites. These chirality-specific changes induced in UV–vis absorption during catalysis enabled the establishment of analyte-specific calibration curves for D-DOPA, L-DOPA, and enantiomeric compositions in D/L-DOPA mixtures, achieving highly enantioselective sensing of DOPA enantiomers. This sensing platform demonstrated high sensitivity (limit of detection: 3.6 µM), excellent selectivity, and significant potential for practical applications. These findings provide novel insights for developing superior enantioselective sensors with high accuracy. Graphical Through the self-assembly of L-cysteine (Cys) and Fe 2+ , we constructed a novel chiral L-Cys-Fe 2+ nanozyme. This nanozyme achieved high enantioselectivity in discriminating 3,4-dihydroxy-D/L-phenylalanine (D/L-DOPA) due to enantioselective adsorption. This approach constitutes a promising new platform for reliable enantiomer detection.

Porous carbon materials attract great interest due to their wide range of applications in electrochemical energy systems, especially in structured and pore size-tunable carbon materials prepared by template-assisted methods. In this study, a solvent-mediated polymerization-induced self-assembly strategy is designed for the synthesis of hierarchical double-shell-layer porous carbon nanospheres, and screened out the carbon nanospheres N-doped hierarchical meso-microporous carbon spheres (NPCS)-40 with the best morphology and performance by exploring the effects of different 1,3,5-trimethylbenzene contents, different cosolvent ratios, different cosurfactant ratios, as well as different ethylenediamine and resorcinol contents on the carbon nanospheres’ structure. The resulting carbon nanospheres exhibit a specific capacitance of 249 F g −1 in a supercapacitor with a current density of 0.5 A g −1 and 139.4 F g −1 in a symmetric supercapacitor with excellent stability, which is maintained at 117% after 5000 charging and discharging cycles. Graphical Hierarchical double-shell carbon spheres (N-doped hierarchical meso-microporous carbon spheres (NPCS)-40) are synthesized via amine-mediated cosolvent polymerization, achieving tunable meso/microporous structures. Optimized ethanol (40 vol%) and surfactant ratios yield hollow, nitrogen-doped spheres with high specific capacitance (249 F g − 1 ) and exceptional cycling stability (117% retention after 5000 cycles). The unique pore architecture enhances ion transport, enabling superior supercapacitor performance.

Reactive Oxygen Species (ROS) exhibit a paradoxical dual role in tumor therapy. Tumor hypoxia restricts therapeutic ROS generation, while excessive secondary ROS post-ablation suppresses T-cell function yet promotes M1 macrophage polarization. Semiquinone radical-doped reduced polydopamine nanoparticles (PDA red ) loaded is developed with resiquimod (R848) (PDA red @R848) via π–π stacking. Reduction enriches the nanoparticles with semiquinone radicals, enhancing dielectric properties and dipole polarization under electromagnetic effects. This nanoparticle enables the specific hydrogen radicals (H•)/ROS generation in oxygen-heterogeneous tumor under microwave irradiation. In microwave dynamics therapy (MDT) phase, PDA red converts protons (H⁺) to H• under microwave irradiation in hypoxic regions, targeting cytochrome c and inducing tumor cell apoptosis and immunogenic cell death; PDA red establishes an internal electric field under microwave, facilitating electron–hole separation to produce ROS and trigger ferroptosis in normoxic regions. In post-MDT phase, PDA red ’s intrinsic polyphenols scavenge excess secondary ROS produced by damaged cells, alleviating immunosuppression. Compared with blank control, PDA red @R848 increased CD4⁺/CD8⁺ T-cell infiltration (6.4-fold) and M1 macrophage polarization (2.5-fold M1/M2 ratio elevation). Pro-inflammatory cytokines are significantly reduced, and tumor volume is suppressed by 94.8%. This study proposes an innovative dual-action mechanism coordinating oxygen-adapted radical generation with secondary ROS clearance to reprogram redox/immune homeostasis for effective liver tumor eradication.

Lead-free perovskite is widely studied in optics and optoelectronics due to its excellent optoelectronic properties. Herein, lead-free perovskite crystals (PCs) doped with two distinct elements are reported. The doping strategy enhances the emission intensity of perovskite and adjusts its emission wavelength. The fluorescence lifetime of La-doped perovskite is 4.08 ms. The yellow light-emitting diode (LED) prepared from Te 4+ -doped perovskite has a color purity of up to 95.54%. The color temperature of the white LED prepared by perovskite is 5910 K. Moreover, aramid chopped fibers (ACFs) and polyphenylene sulfide (PPS) composite fiber paper exhibits luminescent properties under ultraviolet (UV) light after modification with perovskite crystals. Luminescent fibers retains the original flexibility and exhibits good luminescent stability. After 48 h of exposure to various industrial simulated exhaust gases, no significant luminescence attenuation or quenching phenomena are observed in the luminescent fibers. In addition, the composite fibers modified with perovskite also exhibit piezoelectric properties. The maximum output voltages of perovskite-modified piezoelectric fibers doped with La 3+ and Te 4+ are 150 V and 48 V, respectively.

Inflammatory bowel disease (IBD) is a chronic inflammatory disorder driven by genetic susceptibility, immune dysregulation, and intestinal barrier dysfunction. Current therapies primarily target immune suppression but show limited efficacy in barrier repair. Here, carbon dots derived from the Chinese herbal medicine Dendrobium officinale (DO-CDs) , which exhibit antioxidant enzyme activity, are synthesized using a hydrothermal method. These DO-CDs, characterized by an abundance of surface functional groups, are demonstrated to scavenge ROS, suppress M1 macrophage polarization, as well as downregulate pro-inflammatory cytokine expression. In both acute and chronic colitis models, DO-CDs demonstrate multimodal barrier-repair properties. It is shown that DO-CDs can notably restore colon length, reduce the infiltration of inflammatory cells, and enhance both the quantity of goblet cells and the expression of mucins. Furthermore, the expression of intestinal epithelial tight junction proteins is significantly upregulated following DO-CDs treatment, thereby effectively strengthening the intestinal epithelial barrier function. Importantly, DO-CDs modulate the Th1/Treg ratio by downregulating the proportions of dendritic cells and M1 macrophages, thus reestablishing intestinal immune homeostasis. These coordinated actions on the mucus-epithelium-immune triad demonstrate the unique capacity of DO-CDs for holistic barrier reconstruction. The work provides a mechanistic foundation for herbal precursor-derived carbon dots as multi-target therapeutics in IBD.

Metallic nanomaterials serve as compact integrated modulators in ultrafast multiwavelength photonics. Engineered bimetallic alloy nanoparticles exhibit enhanced and tunable optical properties that surpass those of single-component systems by alloying. Here, bimetallic PtNi octahedral alloy nanoparticles are demonstrated as a promising material platform for ultrafast multiwavelength lasers, exhibiting exceptional nonlinear optical responses across the entire near-infrared spectrum. Q-switched laser operations were successfully achieved at 1028.5, 1561.2, and 1911.2 nm, utilizing PtNi octahedral alloy nanoparticles. Furthermore, utilizing the four-wave mixing effect induced by PtNi alloys, simultaneous five-wavelength lasers were realized with channel spacings of 1.7 and 2.2 nm in the 1- and 2-µm bands, respectively. It is found that PtNi alloys are comparable nonlinear optical modulators with other typical nanomaterials in ultrafast multiwavelength photonics. Moreover, first-principles calculations reveal that substantial 3D states of the Ni concentrated near the Fermi level are the major cause of the enhanced optical absorption, where the surface Ni plays an important role. This work establishes a novel paradigm for developing advanced material platforms for nonlinear optical modulation, paving the way toward breakthroughs in ultrafast multiwavelength photonic systems.

Acquiring multidimensional tumor and tumor-associated vascular information is essential for accurate diagnosis and treatment planning of glioma, yet effective imaging methods are still lacking. Here, ultrasmall manganese ferrite nanoparticles (UMFNs) are developed as a dual contrast-enhanced T 1 -weighted imaging (T1WI) and susceptibility-weighted imaging (SWI) probe for multidimensional diagnosis of glioma. The UMFNs are synthesized through thermal decomposition and functionalized with polyethylene glycol, ensuring excellent water dispersibility and biocompatibility. Characterization studies confirm the nanoparticles’ uniform size (3.8 nm) and high stability in various media. High r 1 (6.8 m m −1 s −1 ) and r 2 * (95.1 m m −1 s −1 ) values demonstrate the superior T 1 and T 2 * enhancement capabilities of UMFNs. In vivo imaging on a 3.0 T magnetic resonance imaging (MRI) scanner demonstrates that UMFN-enhanced SWI clearly delineates tumor margins and provides sustained tumor enhancement in ultrasmall orthotopic glioma (<2 mm). Besides, UMFN-enhanced SWI reveals distinct vascular structures associated with the glioma, including tortuous, thickened vessels indicative of tumor-induced angiogenesis. Whole-brain histological analysis corroborates these findings, demonstrating dense tumor proliferation and vascular remodeling. These results highlight the potential of UMFNs as a dual-enhanced agent for the early detection and high-resolution vascular mapping of glioma, providing an advanced multidimensional method for precise diagnosis of brain tumors.

This study tackles the poor low-temperature performance of lithium-ion batteries through a synergistic strategy that modulates electrode–electrolyte interfacial chemistry via coordinated temperature and electric field control. The research uncovers distinct interfacial evolution mechanisms: at −20 °C, strengthened solvent–Li + affinity causes solvation structure reorganization and interfacial deterioration, whereas at 25 °C, enhanced anion participation promotes formation of stable inorganic-rich interphases. Reduced electric field intensity further facilitates the construction of stable interfaces. Based on these findings, a variable-temperature constant-current cycling protocol with periodic room-temperature activation is developed. This approach effectively restores stable interfaces and substantially minimizes polarization, enabling commercial lithium iron phosphate (LFP) batteries to maintain nearly 100% initial capacity after 150 cycles at −20 °C—significantly surpassing conventional strategies (80.4% retention). Notably, this optimization method regulates interfacial chemistry through external field parameters without electrolyte formulation changes, demonstrating both theoretical innovation and engineering practicality. This work provides a novel paradigm for low-temperature battery design by decoupling interfacial regulation from material modification.
