A novel Ti-BTC with a mesoporous structure and uniformly dispersed Ti-OH sites was successfully synthesized. • Ti-BTC exhibits outstanding ODS activity; 99.5% of sulfur (1000 ppm) can be oxidized at 40 °C within 20 min. • The ODS activity of Ti-BTC at 40 °C reaches 52.4 mmol h −1 g −1 , exceeding that of most previously reported Ti-MOFs. • DFT results reveal that OH anchored on Ti sites react with H 2 O 2 to form Ti-OOH species that dominate ODS efficiency. • The mesoporous architecture enhances the accessibility of sulfur to Ti-OOH active sites and promotes rapid mass transfer. Desulfurization represents a pivotal process to produce ultraclean fuels, yet the design and fabrication of advanced materials to enhance desulfurization efficiency continues to pose significant challenges. Herein, a novel mesoporous titanium-based organic frameworks (Ti-BTC) was successfully synthesized via a solvothermal route. The optimized Ti-BTC exhibits outstanding oxidative desulfurization (ODS) performance, enabling the complete oxidation of various sulfur-containing compounds (1000 ppm sulfur) into the corresponding sulfones at 30 °C within 14 min or at 50 °C within 3 min with H 2 O 2 /sulfur (O/S) molar ratio of 5. Notably, even when molar ratio of O/S is reduced to 2.5, 99.5% of sulfur species are oxidized at 40 °C within 20 min. The ODS activity of Ti-BTC at 40 °C attains 52.4 mmol h −1 g −1 , surpassing most previously reported Ti-containing organic materials. Density functional theory calculation and comprehensive characterization results demonstrate that Ti-OH group anchored on vacancy Ti sites readily react with H 2 O 2 to generate peroxo-titanium intermediate, which efficiently oxidize pre-adsorbed sulfur and thus determine the overall ODS efficiency. Additionally, the mesoporous structure of Ti-BTC improves the accessibility of sulfur to in-situ-generated Ti-OOH species and facilitates rapid mass transfer, which synergistically enhances the catalytic performance.

Closed-loop recycling of PAEK composites via dynamic imination strategy. • Intractable PAEK is converted into a soluble amorphous intermediate. • Continuous fibers are non-destructively recovered with >95% strength retention. • The amorphous intermediate can regenerate into PAEK resin. • Recycled matrix retains pristine thermomechanical performance over multiple cycles. The recycling of high-performance fiber-reinforced PAEK composites is hindered by a paradox: the chemical inertness and crystallinity that provide exceptional stability also make their deconstruction extremely difficult, while conventional harsh methods irreversibly degrade both fibers and resin matrix. Herein, we report a targeted structural reconstruction strategy that enables the mild amorphization and closed-loop recovery of high-value composite components. With PEEK as a model, ZnCl 2 is utilized to catalyze the targeted imination of carbonyl groups. As verified by rigorous density functional theory (DFT) calculations, this specific coordination significantly reduces the kinetic activation barrier, enabling the disruption of the dense crystalline structure under extraordinarily mild conditions. Crucially, this crystalline-to-amorphous transition fundamentally overcomes mass transfer limitations, enabling the non-destructive extraction of continuous reinforcing fibers while retaining >95% of their pristine mechanical properties. After fiber separation, acid-catalyzed hydrolysis triggers structural reconstruction of the PEEK molecular backbone, largely restoring its original semi-crystalline morphology and key thermomechanical properties. This versatile recycling platform exhibits broad applicability across PAEK-based materials with diverse molecular architectures and maintains stable performance over three consecutive recycling cycles. This work provides a promising strategy with potential for further process development of high-performance PAEK composites.

Ratiometric biosensor overcomes challenges of single-signal biosensors. • Dual-electrode design ensures self-calibration and compensates for errors. • Achieves a low detection limit (0.004 mM) and high accuracy (>97.29%). • Higher recovery compared to the Nash assay in real food matrices. • Demonstrates excellent reproducibility in a complex food matrix. Global food safety requires reliable biosensors in complex matrices. Yet, conventional single-signal electrochemical biosensors suffer from high inter-electrode variability (RSD <12.14%) and low accuracy (<87.84%) due to common-mode signal fluctuations. This study presents a ratiometric biosensor with a dual-electrode design that enables calculation of the current ratio (I WE2 /I WE1 ) between a formaldehyde dehydrogenase-functionalized sensing electrode and an inert graphene reference to mitigate systemic fluctuations. This self-calibrating configuration reduced variability (RSD of 6.92%), improved accuracy (>97.29%), and minimized interference effects (from 7.54% to 1.52%). Spanning a linear range of 0.02–0.50 mM with a LOD of 0.004 mM, the biosensor achieved 97.22–103.87% recovery in coffee samples (RSD = 0.21%). Validation against the Nash assay showed strong correlation (R 2 = 0.995) with comparable accuracy at 0.10–0.50 mM concentrations, yet up to nine-fold higher accuracy at 0.02 mM ( p < 0.05), confirming its superior suitability for practical application in food safety monitoring.

Currently, silver nanowires (AgNWs) are among the most widely studied materials for flexible transparent electronics. Nevertheless, their practical implementation is hindered by inherent limitations in environmental stability and mechanical robustness. To address these challenges, this study presents a straightforward fabrication approach for a multifunctional flexible transparent conductive film (TCF) that exhibits superior mechanical integrity and long-term stability. Through simple solution processing, multiple functional layers were constructed on a flexible substrate. Among them, AgNWs serve as the conductive layer, SiO 2 NPs as the anti-reflection layer, and AZO as the protective layer. Accordingly, an AgNWs/SiO 2 /AZO TCF (ASZ) was fabricated, exhibiting a sheet resistance of 2.85 Ω/sq, a transmittance of 80.8% at 550 nm, and a figure of merit (FoM) value of 588. This TCF not only combines Joule heating and electromagnetic shielding but can also be used to fabricate OLED devices. A transparent Joule heating device fabricated from this TCF achieves a rapid thermal response, reaching 130 °C at 3 V while maintaining stable operation over extended durations. Furthermore, the film delivers an electromagnetic interference (EMI) shielding effectiveness of 32 dB across the X-band (8.2–12.4 GHz). Critically, owing to the outstanding oxidation resistance and superior surface planarity of the AZO layer, the film’s sheet resistance increases by only 24% after a rigorous 70-day aging test under ambient conditions. When employed as the anode in OLED devices, the TCF enables a maximum luminance of 17,400 cd/m 2 . Collectively, this work establishes a scalable, simple, and highly stable strategy for developing multifunctional transparent electronic devices.

Highly efficient oxygen evolution reaction (OER) depends not only on the activity of the metal centers but also on the rapid removal of protons from surface oxygenated intermediates. Although exogenously constructed proton relays can facilitate proton transfer, they often suffer from rapid structural collapse and deactivation under strongly oxidative OER conditions. To address this issue, we propose a plausible novel intermediate functionalization strategy that converts the *OH intermediates generated in situ during the OER process into endogenous proton relays, fundamentally circumventing the deactivation problem of exogenously proton relays. Using a controllable partial reconstruction Ni 3 S 2 /NiOOH/CoOOH heterostructure, the retained highly conductive Ni 3 S 2 skeleton triggers electron depletion in the interfacial amorphous layer. Combined in situ Raman spectroscopy and DFT calculations indicate that this electron depletion favors the preferential and strong anchoring of *OH species at specific Ni–Co bridge sites. Subsequent isotope experiments and DFT calculations further support a plausible mechanistic hypothesis in which these anchored *OH species may function as endogenous proton relays, facilitating the deprotonation of oxygenated intermediates on adjacent co sites. Consequently, the catalyst achieves a low overpotential of 139 ± 2 mV at 10 mA cm −2 , a small Tafel slope of 37.01 ± 0.45 mV dec −1 , and stable operation for 300 h. this study offers new insights into designing accelerated proton transfer pathways under harsh anodic OER conditions Download: Download high-res image (138KB) Download: Download full-size image

Friedel–Crafts acylation yields β-diketone polymer superior to Claisen condensation. • The probe exhibits a vivid green-to-blue shift and intensity enhancement with Al 3+ . • Conformation restriction by Al 3+ coordination enables fluorescence change. • Dual-mode sensing enables both visual screening and precise quantification. • Results in wheat food samples show high consistency with standard ICP-MS methods. Aluminum additives in flour-based foods pose safety concerns and require rapid monitoring. This study presents a high-performance β-diketone main-chain polymer fluorescence sensor synthesized via Friedel–Crafts acylation for specific aluminum detection. This preparation method yielded a polymer with superior sponge-like porosity and extended π-conjugation. Upon Al 3+ coordination, the probe exhibits a distinct fluorescence transition from dim green to brilliant deep blue, enabling visual identification. The response follows a positive cooperative logistic model, achieving a limit of detection of 1.78 μmol/L. Mechanistic studies attribute signal enhancement to a synergistic effect, where coordination restricts the conformational relaxation of the polymer backbone to suppress non-radiative decay while simultaneously increasing radiative oscillator strength. Validated in wheat derivatives with a calibration strategy, the method achieved quantitative results consistent with inductively coupled plasma mass spectrometry. This work highlights the value of backbone-integrated recognition sites and conformational restriction for sensing. A β-diketone main-chain polymer fluorescence sensor addresses the challenge of monitoring aluminum in wheat-based foods. The probe exhibits a positive cooperative logistic response to Al 3+ , characterized by a vivid green-to-blue emission shift. By leveraging a coordination-induced restriction of main-chain conformational relaxation mechanism, the sensor achieves excellent selectivity and sensitivity, allowing for both naked-eye inspection and precise instrumental quantification in real samples.

Architectured ceramic absorbers are expected to simultaneously withstand mechanical loading and attenuate electromagnetic (EM) waves over a broad frequency range; however, achieving an optimized balance between structural integrity, impedance matching, and dielectric loss remains a major obstacle. In this work, a rhombus-like triply periodic minimal surface (TPMS) SiOC ceramic was fabricated and subsequently decorated with carbon nanowires (CNWs) along the ridge regions through an integrated process involving vat photopolymerization, polymer-derived ceramics (PDCs) conversion, chemical vapor deposition (CVD), and thermal treatment. This structural design establishes a hierarchical conductive–dielectric framework, where the TPMS geometry and ridge-oriented CNWs distribution collectively regulate mechanical and EM responses. The TPMS skeleton provides continuous load-transfer pathways while promoting EM wave penetration and multiple reflections, whereas the CNWs network introduces conductive channels and additional polarization interfaces to enhance EM dissipation. With a CNWs content of 3.95 wt%, the CNWs/SiOC ceramic delivers a minimum reflection loss (RL min ) of −54.66 dB and an effective absorption bandwidth (EAB) of 6.9 GHz at 3.35 mm. CST-based EM simulations confirm that the CNWs/SiOC architecture maintains a favorable dielectric response from 4 to 18 GHz, supporting broadband attenuation. In addition to its absorption capability, the sample containing 7.75 wt% CNWs reaches a compressive strength of 21.84 MPa, indicating the contribution of the architectured ceramic framework and ridge-oriented CNWs reinforcement to mechanical robustness. The improved attenuation is associated mainly with localized electric-field enhancement near the ridges, conductive dissipation through the CNWs network, and polarization loss generated by heterogeneous interfaces. These findings demonstrate that the ridge-oriented CNWs modification of architectured SiOC ceramics provides an effective strategy for the integrated realization and simultaneous optimization of load-bearing capability and broadband EM wave absorption.

Constructing heterojunctions is an effective strategy to enhance charge carrier separation and photocatalytic performance. In this study, a Bi 4 O 5 Br 2 /InVO 4 S-scheme heterojunction composite was prepared by a solvothermal method. The physicochemical properties were thoroughly investigated using various characterization techniques. Visible-light degradation experiments of ciprofloxacin (CIP) showed that the optimal sample, 5% Bi 4 O 5 Br 2 /InVO 4 (BI-5), exhibited the highest degradation activity (92.77%) along with excellent cycling stability. The effects of different environmental factors on the degradation performance were also systematically studied. The enhanced activity is attributed to the synergistic effect of the S-scheme heterojunction and increased oxygen vacancies. The S-scheme charge transfer, driven by the IEF at the heterointerface, enables spatial separation of photogenerated electrons and holes while preserving strong redox potentials, with reductive electrons accumulating in Bi 4 O 5 Br 2 and oxidative holes remaining in InVO 4 . Meanwhile, the introduction of InVO 4 creates abundant oxygen vacancies. These vacancies act as electron capture centers to suppress bulk recombination, introduce in-gap states that facilitate interfacial charge transfer, and provide additional active sites for surface reactions. Consequently, the S-scheme junction and oxygen vacancies jointly promote the separation, migration, and surface utilization of charge carriers, leading to significantly improved photocatalytic performance.

Constructing continuous, highly oriented hexagonal boron nitride (h-BN) ceramic networks within organic phase change materials (PCMs) is a paramount strategy to overcome their intrinsic low thermal conductivity and leakage flaws. However, fabricating such anisotropic ceramic skeletons via conventional methods routinely suffers from high chemical processing costs, energetic calcination, or structural fragility under high filler loading. Herein, we report a robust and highly anisotropic h-BN thermal network successfully engineered via an eco-friendly water-based “biomass-templating” approach. Guided by a temperature gradient during directional freezing, upcycled coffee-waste-derived cellulose nanofibers (CNFs) serve as green structure-directing “rebars” to capture and vertically align flake-like h-BN ceramic “aggregates,” which are seamlessly welded into a stable 3D network by a sodium alginate “ionic cement”. This biomimetic processing strategy enables the composite to retain an exceptional organic PCM (n-eicosane) loading of 90 wt% while completely preventing high-temperature leakage. Benefiting from the continuous and low-thermal-resistance axial ceramic pathways, the optimized phase change composite delivers a remarkable axial thermal conductivity of 0.94 W m −1 K −1 (a ∼261% enhancement over the pure organic matrix) and a high latent heat of 182.06 J/g. Concurrently, the multi-scale chemical cross-linking endows the porous ceramic framework with an unprecedented compressive stress of 876.6 kPa, allowing it to support 1282 times its own weight without collapse, while maintaining robust near-superhydrophobicity (water contact angle of 146.85°). Practical outdoor miniature building model evaluations confirm that the composite panels exhibit superior dynamic thermal regulation, achieving an indoor peak temperature suppression of 8 °C and a 2-h thermal time lag. This work provides a facile, sustainable, and eco-friendly biomimetic templating strategy for designing highly oriented advanced ceramic networks for efficient thermal energy storage.

Inspired by biological strategies, we developed an environment-adaptive Janus metafabric via multiscale interfacial electrospinning and soft-template-assisted phase separation strategy. • The Cyphochilus scale cooling layer achieves outstanding solar reflectance (94.8%) and mid infrared emissivity (98.1%), the Photon-trapping thermal layer achieves high solar absorptivity (81.8%). • Gradient porous architecture promotes directional sweat transport for enhanced wearing comfort. To mitigate heat stress during outdoor activities, passive radiative cooling (PRC) has been recognized as promising candidate for personal thermal management (PTM). However, conventional single-layer cooling fabrics cannot meet dynamic environments and wearing comfort. Herein, inspired by the highly scattering porous scales of Cyphochilus beetles, we developed an environment-adaptive Janus metafabric (EAJM) composed of a Cyphochilus scale-inspired cooling (CSC) layer and a Photon-trapping thermal (PTT) layer via multiscale interfacial electrospinning and soft-template-assisted phase separation (ST-PS) strategy. The EAJM combines hydrophilic PAN/SiO 2 fibers and hydrophobic PLA/PPy fibers into a functional Janus architecture. The CSC layer achieves outstanding solar reflectance (94.8%) and mid-infrared emissivity (98.1%), whereas the PTT layer serves as an efficient photon-trapping absorber (81.8%). This asymmetric spectral modulation enables dual-mode thermal management beyond the capabilities of conventional single-layer cooling fabrics. In outdoor tests, EAJM achieved outstanding radiative cooling (∆T max = 7.2 °C) and photothermal performance (∆T max = 2.8 °C) compared with bare skin. Meanwhile, the net cooling and heating power reached 113.7 W m −2 and 363.1 W m −2 , respectively. Furthermore, the wettability and pore-size gradient of EAJM facilitate anisotropic capillary-driven moisture transport, enabling rapid sweat wicking and evaporation.

Cellulose has garnered widespread attention in the field of triboelectric nanogenerators (TENGs) due to its unique properties. However, constrained by the inherent characteristics of the material, the application of cellulose in TENGs is mostly limited to positive triboelectric materials. In this study, a TEMPO-oxidized nanocellulose (TOCN) aerogel film modified with polycarboxyl silicone oil was successfully prepared and utilized as a cellulose-based negative triboelectric material. By integrating a calcium copper titanate (CCTO)-doped, cross-linked amine-modified TOCN composite aerogel film, a cellulose-dominant TENG device was successfully fabricated, achieving an output voltage of up to 12.5 V. In addition, TOCN was employed as a reinforcing filler for PVDF-based negative triboelectric materials. After undergoing further surface roughening or stretching treatments, the composite material achieved an output voltage of 90 V, exhibiting excellent cycling stability, retaining 99.3 % of its initial output voltage after 5000 continuous operating cycles. This study provides valuable insights into the development of TENG devices based on renewable cellulose-derived components, offering new strategies for constructing high-performance cellulose-dominant TENGs.

Solar-driven interfacial evaporators represent a promising approach to alleviate global freshwater scarcity. However, practical applications still face challenges such as low evaporation efficiency, salt scale accumulation, and unstable evaporation. Therefore, we polymerized and deposited polydopamine (PDA) and hydrothermally synthesized CuS nanoparticles onto a polyimide (PI) aerogel to prepare a superhydrophilic porous CuS/PDA@PI nanofibrous aerogel. The aerogel achieved >97% light absorption over 200-2500 nm and a water evaporation rate of 1.963 kg m −2 h −1 under one sun irradiation (1 kW m −2 ). The apparent total evaporation efficiency reached 119.8%, exceeding the theoretical limit due to additional environmental heat harvesting. Even after 1200 min of cycling, the aerogel maintained an apparent total evaporation efficiency of 116.6%. The evaporator maintained an apparent total evaporation efficiency of 88.7% under a salt (20%) environment and exhibited self-cleaning performance. Furthermore, the aerogel exhibited purification performance for dye wastewater, acidic and alkaline solutions, and seawater. This superhydrophilic evaporator provides a viable route for practical seawater desalination.
