Maintaining optimal body temperature in cold outdoor environments is crucial for human health and performance. However, developing effective thermal management fabrics for extreme outdoor conditions remains challenging, as it necessitates integrating thermal insulation properties with diversified heating capabilities while ensuring flame-retardant safety. Herein, we report asymmetrically structured multimodal thermal management nonwoven fabrics (MTMNFs) by strategically incorporating carbon black (CB) and silver nanowire (AgNW) functional layer on opposite sides of a flame-retardant phenolic resin meltblown mat (PRMBM) substrate. This design synergistically integrates thermal insulation, solar heating, Joule heating, and radiative heating effects, while maintaining superior flame-retardant properties. The PRMBM demonstrates outstanding thermal insulation properties (thermal conductivity coefficient 0.037 W/m·K) and inherent flame retardancy (LOI=33.96%), providing a robust foundation for multifunctional thermal management. The outer CB layer demonstrates highly efficient photothermal conversion, achieving surface temperatures exceeding 80°C under standard illumination. Simultaneously, the inner AgNW layer provides both efficient Joule heating (reaching 94°C at 3 V) and radiative heating (elevating skin temperature by approximately 3°C) properties. This multifunctional integration, coupled with the substrate's outstanding flame-retardant and thermal insulation properties, establishes MTMNFs as an ideal solution for demanding outdoor thermal management applications. Our approach fundamentally overcomes the limitations of conventional thermal management materials that typically excel in only one specific function and addresses the barriers posed by their lack of flame-retardant safety, thereby providing a highly promising solution for advanced outdoor thermal management materials with broad applications in emergency response, military operations, and recreational outdoor activities.

The urea oxidation reaction (UOR), with its low theoretical potential, can replace the oxygen evolution reaction (OER) at the anode in water electrolysis, thereby reducing the thermodynamic barrier of electrochemical water splitting. However, in practical UOR electrocatalysts, the adsorption competition between urea and OH⁻ constitutes a kinetic bottleneck. Conventional catalysts lack dynamic regulation means, which ultimately leads to the occurrence of competitive adsorption. In this study, we constructed a CuxS/FeS/NF heterojunction electrocatalyst via hydrothermal methods, achieving highly efficient catalysis for UOR-assisted overall water splitting. The heterojunction features an open and disordered hierarchical porous structure, significantly increasing the specific surface area and active site density (with a double-layer capacitance of 8.33 mF cm -2 ). More importantly, the reversible Cu + /Cu 2+ valence cycling on the heterojunction surface dynamically modulates urea adsorption sites, addressing the issue of OH -occupying active centers and accelerating reaction kinetics (Tafel slope as low as 26.28 mV dec -1 ). In-situ Raman tests confirm that Cu 2+ forms strong coordination with -NH₂ via empty orbitals, while Cu + weakens the adsorption of OH⁻ through high electron density; the two species synergistically accelerate the reaction kinetics. Electrochemical tests reveal that in the UOR||HER system, CuxS/FeS/NF only requires a potential of 1.35 V vs. RHE to achieve a current density of 10 mA cm -2 , while for the HER, it needs merely 78 mV to reach the same current density. When applied to UOR-assisted overall water splitting in a 1 M KOH + 0.33 M urea electrolyte, the system requires only 1.440 V vs. RHE cell voltage to deliver a current density of 50 mA cm -2 and maintains stable operation for 60 hours, with a urea degradation rate of 66.4% after 20 hours. This work, through the dynamic regulation mechanism of copper valence cycling, provides a novel approach for designing UOR catalysts with both high activity and stability, holding significant application potential in low-energy hydrogen production and wastewater treatment.

A phosphorylated polyethyleneimine-functionalized magnetic covalent organic framework (mCOF-PEI-PO 3 -Ti 4+ ) was engineered for highly selective and efficient enrichment of phosphopeptides from complex biological samples. The nanocomposite was constructed by growing a vinyl-functionalized covalent organic framework on Fe 3 O 4 microspheres, followed by grafting of hyperbranched polyethyleneimine and subsequent phosphorylation to introduce a high-density Ti 4+ -chelating interface. By integrating immobilized metal ion affinity chromatography (IMAC) with the enhanced hydrophilicity and multi-site hydrogen-bonding capability of the phosphorylated PEI layer, the composite demonstrated outstanding enrichment performance. This included an ultralow detection limit (0.5 fmol), outstanding selectivity (1:2000), high loading capacity (50 mg·g −1 ), and excellent reusability (10 cycles). The material successfully enriched endogenous phosphopeptides from human saliva and serum. Furthermore, it enabled the comparative phosphoproteomic profiling of serum samples from colorectal cancer (CRC) patients, revealing a distinct CRC-associated phosphopeptide signature. Gene Ontology analysis indicated that the identified phosphoproteins were significantly enriched in lipid metabolism and receptor signaling pathways, whereas serine protease inhibitor activity was markedly downregulated in CRC samples. These findings suggest that dysregulated lipid metabolism may contribute to CRC progression through inflammatory modulation. This study establishes the mCOF-PEI-PO 3 -Ti 4+ composite as a robust and reliable platform for clinical phosphoproteomic analysis.

A new mixed-mode hybrid stationary phase is synthesized, followed by its characterization using BET analysis, SEM, FTIR spectroscopy and EDX analysis. 4, 4′-Biphenol was esterified using ethyl chloroacetate in the presence of potassium carbonate, followed by carboxylation using ethanol/water (9 : 1 v/v%) in the presence of NaOH. The product was treated with nickel nitrate hexahydrate, resulting in the formation of nickel-containing 4,4′-biphenol. The newly synthesized stationary phase was completely characterized through 1H-NMR, 13C-NMR, FTIR, EDX, FE-SEM, BET, particle size distribution, and XRD resulting in characteristics in line with proposed material and best fitting of the material to be used as the new separation media in liquid chromatography. The resultant material was packed in a stainless-steel column (200 mm long × 0.2 mm internal diameter) using a slurry packing machine and tested as a separation media in liquid chromatography. The newly developed column resulted in the separation of different analytes belonging to different classes, such as polyaromatic compounds (PACs), benzene derivatives, and a set of nucleotides, with average plate counts of 272 100, 243 000, and 244 800 plates m−1, respectively, under the optimized mobile phase of acetonitrile/methanol/15 mM ammonium formate in the ratio of 60/30/10 v/v% at pH 6.5 and a flow rate of 25 µL min−1.

Biphasic hydrogels hold significant potential in fabricating isotropically tough materials through structural synergy, yet their strength remains constrained by interfacial modulus mismatch. Herein, a modulus-matched rubbery and entangled phases synergistic enhancement strategy is proposed to construct biphasic hydrogels by continuous phase separation. The molecular chain aggregates of the rubbery and entangled phases with nano crystalline domains are induced by continuous phase separation via reducing solvent polarity and breaking polymer-solvent hydrogen bonds, respectively. The key to achieving synergistic enhancement lies in modulus matching between the rubbery and entangled phases. Biphasic synergistic enhancement hydrogels exhibit excellent mechanical properties including a tensile strength of 38.76 MPa, a toughness of 137.03 MJ m −3 , a modulus of 58.36 MPa, and a fracture energy of 130.21 kJ m −2 . Biphasic hydrogels exhibit a low strength decay of 2.73% during ten cycles of testing at a strain of 3. Crucially, the modulus-matched biphasic system with crystalline domains transcends the stiffness-fracture energy trade-off boundary. The biphasic hydrogels exhibit heat resistance and stable electrical conductivity, making it suitable for flexible wearable electronics. It can function as a high-performance epidermal bioelectrode for monitoring human electromyography signals, demonstrating the integrated advantages of its strength, flexibility, reversible deformability, heat resistance, and stable ionic conductivity. Biphasic synergistic enhancement strategy paves the way for development of ultrastrong biphasic hydrogels via modulus matching.

This study presents a novel slit evaporation self-assembly method for fabricating freestanding sulfuric acid-treated reduced graphene oxide/commercial graphene films (S-ATrGO/CG). The unique capillary slit-induced self-assembly process facilitates the alignment and stacking of graphene flakes, resulting in a well-ordered, laminated film. The treatment of graphene oxide (GO) with sulfuric acid facilitates the ring-opening of inert functional groups, converting them into active functional groups. Sulfuric acid-treated graphene oxide (ATGO) can serve as an effective binder for adhering commercial graphene flakes. X-ray photoelectron spectroscopy was used to quantitatively analyze the oxygen-containing functional groups in GO, ATGO, and S-ATrGO/CG. A series of electrochemical tests were conducted to investigate the behavior of the S-ATrGO/CG films, which exhibited well-defined redox peaks, indicating the contribution of unreduced oxygen-containing groups to redox reactions and pseudocapacitance. The S-ATrGO/CG films exhibit superior electrochemical performance, with an ultra-high area-specific capacitance of 1,589.78 mF cm-2 at a scan of 5 mV s-1 and an impressive initial capacitance retention of 99.80% after 20,000 cycles at a current density of 50 mA cm-2. This study highlights the potential of S-ATrGO/CG films as high-performance electrodes for supercapacitors, contributing to the advancement of sustainable energy storage systems.

Nanofibrous membranes hold great promise for water purification, yet their performance is often compromised by irreversible membrane fouling and structural instability under applied pressure, which lead to flux decline and poor separation efficiency. To address these challenges, developing membranes capable of energy-efficient, gravity-driven (or ultra-low pressure) separation with robust anti-fouling properties is highly desirable. In this study, a novel SiO 2 @PVDF-HFP electrospun fibrous membrane with superhydrophilicity/underwater superoleophobicity was developed via electrospinning followed by electrostatic-assisted in situ growth of a SiO 2 nanocoating. This approach ensured a uniform and stable silica layer, which is critical for maintaining performance under low driving pressures. The membrane achieved highly efficient separation of diverse oil-in-water emulsions under gravity, with emulsion separation fluxes ranging from 336 to 605 L m −2 h −1 and separation efficiencies above 99 %. Thanks to the uniform silica coating, the membrane maintained its structural integrity and separation performance even under harsh conditions, due to its enhanced mechanical robustness and chemical stability. In a 6 h continuous cross-flow separation test under an ultra-low pressure, the membrane demonstrated excellent operational stability, with over 97.6 % flux recovery and separation efficiency remaining above 99 %. This study not only demonstrates a viable approach to developing high-performance membranes but also highlights the significant energy-saving potential of separation processes operating under gravity or ultra-low pressure for sustainable oily wastewater treatment.

To overcome the low nitrogen use efficiency (<40%) of conventional urea, this study utilizes the metal–organic framework MIL-100(Fe)—characterized by ultrahigh surface area and tunable mesoporosity—as a promising carrier for nano slow-release fertilizers with enhanced nutrient stability. Fourier transform infrared spectroscopy, thermogravimetric analysis, and Brunauer–Emmett–Teller measurements confirmed that urea was uniformly accommodated within the MOF channels in an amorphous, physically adsorbed state without chemical bonding. High-performance liquid chromatography revealed that loading capacity was primarily determined by the urea-to-MOF mass ratio, whereas loading temperature and duration had negligible effects, enabling precise synthesis control. Orthogonal optimization identified the optimal parameters (mass ratio 1:1, 110°C, 7 h), yielding a urea loading of 59.2% and encapsulation efficiency of 51.8%. Release experiments demonstrated a 22.5-fold extension in release duration compared to pure urea, with 87.6% cumulative release over 180 h governed by Fickian diffusion. Furthermore, physical characterization and bench-scale metering tests verified the granules' mechanical adaptability, achieving stable, continuous discharge comparable to urea. This work validates MIL-100(Fe)@UREA as a high-capacity, mechanically viable platform for sustainable and precision nutrient delivery. These results not only highlight the potential of MIL-100(Fe) in advanced slow-release fertilizer systems but also provide valuable insights for designing efficient and environmentally sustainable nutrient delivery platforms.

Immunogenic cell death (ICD) induced by calcium overload holds great promise for reversing the immunosuppressive tumor microenvironment (TME) and improving cancer immunotherapy. However, achieving sustained calcium dysregulation remains a major challenge. Herein, we report a novel nanoplatform, termed Ca@CMPN, which co-delivers calcium hydride and curcumin using a mesoporous polydopamine carrier for synergistic ion-interference and gas immunotherapy. Upon encountering the acidic TME, Ca@CMPN disintegrates to release Ca 2+ , initiating intracellular calcium overload, and concurrently generates hydrogen gas (H 2 ). Crucially, the co-released curcumin acts from within the cell, amplifying the calcium overload by disrupting organellar calcium homeostasis, thereby ensuring robust ICD. Meanwhile, H 2 serves as a potent immunoadjuvant to alleviate oxidative stress and remodel the immunosuppressive TME. Both in vitro and in vivo studies demonstrate that Ca@CMPN effectively inhibits tumor growth and reprograms the TME, as evidenced by enhanced dendritic cell maturation, activation of cytotoxic T cells, and elevated levels of pro-inflammatory cytokines (interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α)). This work presents a paradigm-shifting strategy that synergizes ion-interference therapy with hydrogen immunotherapy, offering a powerful nanoplatform to unlock the full potential of cancer immunotherapy.

Overcoming the sluggish acidic oxygen evolution reaction (OER) is critical for advancing proton exchange membrane water electrolysis (PEMWE) toward large-scale green hydrogen production, yet its development is hindered by the intrinsic trade-off between activity and stability. Herein, we introduce a controllable synthesis strategy to engineer RuO 2 assemblies from ultrasmall Ru nanocrystals supported on carbon via air annealing for efficient acidic OER. This process concurrently induces a Ru-to-RuO 2 crystal transformation and facilitates carbon thermal decomposition, yielding a catalyst (Ru-nano/C-300) with markedly enhanced electrochemically active surface area (ECSA) and superior OER performance, requiring only 218 mV at 10 mA cm −2 , and exhibiting a Tafel slope of 43.8 mV dec −1 and a mass activity 21-fold higher than commercial RuO 2 (c-RuO 2 ) at 1.5 V vs. reversible hydrogen electrode (RHE). Tetramethylammonium cation (TMA + ) poisoning experiments combined with in-situ spectroscopic analyses verify that the catalysts predominantly operate via the adsorbate evolution mechanism (AEM) pathway, while electron paramagnetic resonance (EPR) results indicate that suppressing oxygen vacancy formation is crucial for the reaction mechanism. These results demonstrate vacancy suppression coupled with morphology engineering as a powerful strategy to develop both efficient and durable catalysts for acidic OER.

The precise tailoring of bandgap structures as well as carrier separation and transport behavior via heterojunction engineering can provide a practical and viable pathway for enhancing the performance of low-dimensional semiconductor devices. In this study, a highly photosensitive photoelectrochemical (PEC) ultraviolet (UV) photodetector (PD) based on a SiC/ZnO heterojunction is explored. The surfaces of SiC nanowires are successfully modified using high-quality ZnO nanospheres via a simple hydrothermal process. The as-constructed SiC/ZnO heterojunction nanowire PEC UV PD achieves high photodetection performance—high responsivity (15.76 mA W −1 ), high detectivity (1.827 × 10 10 Jones), excellent external quantum efficiency (5.21%), and fast rise/decay times (186/454 ms), under 375-nm UV illumination. Remarkably, the device exhibits a high photoresponse under different solution concentrations, temperature conditions, and excellent aging stability over long-term operation. Its highly sensitive and reliable photodetection performance could be attributed primarily to the synergy among the type-II charge transfer pathways formed at the SiC/ZnO heterojunction, enhanced photogenerated-carrier separation efficiency, and improved light–matter interactions enabled by the large specific surface area of the ZnO nanospheres. Overall, this study establishes a paradigm for developing highly sensitive PEC PDs suitable for optical communication under harsh underwater conditions, thereby advancing heterojunction and interfacial engineering strategies for next-generation optoelectronics.

Effective hemostasis and pathogenic microorganism clearance are essential primary steps for establishing a stable internal microenvironment during the early stage of wound repair. Therefore, a simultaneous thermal crosslinking-integration strategy was applied to electrospun polyvinylpyrrolidone (PVP) and graphene oxide nanosheets (GO) composite fibers to achieve early-stage intervention for acute wounds. During thermal crosslinking, molecular thermal motion facilitates interactions between PVP and GO via various non-covalent interactions, thereby further stabilizing the macromolecular chains. Specifically, the fabricated PVP-G5 membranes exhibit robust morphological stability in aqueous environments, enabling them to accommodate excessive wound exudate. As a supporting substrate, the fibrous structure of PVP-G5 also facilitates platelet accumulation, thereby providing a favorable physical platform for activating the blood coagulation cascade. Furthermore, the embedded GO nanosheets within the fiber matrix not only ensure biocompatibility but also endow the fibrous membranes with NIR-switched photothermal therapy (PTT), thus achieving broad-spectrum pathogen eradication. These findings demonstrate that the PVP-GO composite fiber membranes, fabricated through the in situ thermal integration strategy during crosslinking, offer significant advantages for managing severe bleeding and infection, with promise for early treatment of acute wounds.
