To promote sustainable road construction and reduce harmful emissions during asphalt paving, a green bio-based adsorbent was developed by activating tea-stalk-derived biochar (TB) using phytic acid, a biodegradable plant-derived organophosphate. This activation introduced a multiple adsorption mechanism that integrates physical adsorption, chemical interactions, and catalytic transformation. The results show that phytic acid significantly increased the specific surface area and micropore volume of TB, facilitated the development of graphitic structures to enhance π–π interactions with aromatic hydrocarbons, and incorporated phosphorus-containing functional groups that enabled chemical bonding and catalytic conversion. At only 0.5% dosage, the activated biochar (PTB) achieved a 64.2% reduction in VOCs and a 93.1% for H 2 S, both exceeding the higher dosage of 2% TB (58.6% and 85.4%, respectively). GC-MS results confirmed that, under the influence of multiple adsorption mechanisms, PTB exhibited higher suppression efficiency across all categories of asphalt fume components, particularly for highly hazardous compounds such as benzene derivatives, alkenes, thiophenes, and ketones. This biochar-based approach offers a sustainable pathway for reducing asphalt-related air pollution during road construction, thereby supporting cleaner transport infrastructure and contributing to improved urban air quality.

The propagation of lithium dendrites and the “shuttle effect” of polysulfide represent two critical challenges hindering the practical application of lithium sulfur batteries (LSBs). Herein, a dual-functional integrated Janus separator is proposed, which simultaneously inhibits the shuttle effect of polysulfide and lithium dendrites to enhance the electrochemical performance of LSBs. On the lithium metal anode interface, directional denaturation treatment was first applied to increase the α-helix content in soy protein isolate (SPI), yielding α-SPI with enhanced Li+ affinity. Phytic acid (PA) served simultaneously as cross-linker and acidity regulator, anchoring α-SPI nanoparticle onto carboxylated cellulose nanofibers (C–CNF). The resulting composite was uniformly sprayed onto the separator to construct a lithiophilic α-SPI@C–CNF framework, which homogenizes Li+ flux and suppresses lithium dendrite. At the cathode interface, the made-to-measure three-dimensional carbon (M-3DC) physically entraps lithium polysulfides and thus prevent the shuttle effect. Finally, the LSB using the Janus separator delivers a high initial capacity of 938 mAh g–1 and exhibits an excellent operation stability by retaining 537.8 mAh g–1 after 1000 cycles (with a capacity degradation rate of only 0.043% per cycle). This study presents a versatile approach to simultaneously mitigate the intrinsic limitations of both the lithium metal anode and the sulfur cathode in LSBs.

Flexible supercapacitors have emerged as promising energy storage devices, owing to their high power density and long cycle life. However, the development of electrode materials with high specific capacitance, superior electrochemical and mechanical stability remains a critical challenge. In this work, we report a facile strategy for fabricating cellulose nanofiber (CNF)-carbon nanotube (CNT)@polyaniline (PANI) nanocomposite aerogels via TEMPO oxidation, freeze-drying, and in-situ polymerization. The CNFs serve as a dispersive scaffold to uniformly distribute CNTs, forming a three-dimensional (3D) interconnected network, while PANI coats the CNF-CNT hybrid to construct a core-shell structure, enhancing pseudocapacitive performance. The resulting CNF-CNT@PANI aerogel exhibits a hierarchical porous structure with a high specific surface area of 121.4 m 2 g -1 and low density of 12.8 mg cm -3 . The assembled flexible supercapacitors deliver a high areal specific capacitance of 722.4 mF cm -2 at 2 mA cm -2 , long-term capacitive cyclic stability (86% capacitance retention after 3000 cycles), and remarkable mechanical stability (95.2% capacitance retention after 200 bending cycles). Additionally, the device achieves a maximum areal energy density of 99.5 μWh cm -2 at a power density of 1005.4 μW cm -2 , outperforming many reported PANI-based supercapacitors. This work provides a feasible approach for designing high-performance flexible electrode materials for next-generation energy storage systems.

Uranium serves as the core fuel for nuclear energy, and efficient uranium extraction from seawater is of great strategic significance for alleviating the shortage of terrestrial uranium resources. However, traditional metal-organic framework photocatalysts generally suffer from severe carrier recombination, weak visible-light response, and scarce active sites, which severely restrict their uranium removal performance in complex seawater systems. Herein, phytic acid was used to controllably etch bimetallic MOF (NH 2 -MIL-68(In/Fe)) to construct phytic acid-functionalized bimetallic MOF (NH 2 -MIL-68(In/Fe)-PA) with a hollow structure. The obtained hollow NH 2 -MIL-68(In/Fe)-PA possesses abundant phosphate groups on its surface and within its pores, providing numerous active sites for uranium adsorption. Meanwhile, phytic acid etching generates coordination defects, which facilitate local electron separation within NH 2 -MIL-68(In/Fe) and thus boost the performance of photocatalytic uranium reduction. The U(VI) reduction rate constant reaches 3.68 × 10 −4 g/(mg·min), 1.3 times that of the NH 2 -MIL-68(In/Fe), and the uranium removal efficiency reaches 91.1% within 120 min. The catalyst exhibits consistently high removal efficiency, strong anti-interference ability, and excellent selectivity. This work proposes a universal green modification strategy mediated by phytic acid, providing a new route for efficient photocatalytic uranium extraction.

Replacing high-performance synthetic fibers with sustainable bio-derived alternatives is critical for mitigating microplastic pollution but remains limited by the inferior mechanical performance of biomass-derived fibers. Here, we present bioinspired cellulose metafibers (Meta-CFs) enabled by a scalable hydrodynamic twisting strategy, wherein an asymmetric microfluidic field precisely guides the formation of continuously twisted architectures within a chemically cross-linked network, thereby locking in the ordered configuration and markedly suppressing defect accumulation. Multiscale experiments and simulations reveal that this strategy promotes efficient stress delocalization and cooperative load transfer. The resulting Meta-CFs achieve an unprecedented maximum tensile strength of 3.29 GPa (average 3.06 ± 0.23 GPa) and a toughness of 349.5 MJ m −3 , simultaneously rivaling the strength of high-performance synthetic fibers and the toughness of natural spider silk. Furthermore, encapsulating multiple individual Meta-CFs with calcium alginate effectively scales up the bundle diameter while preserving GPa-level strength and full biodegradability. This upscaling strategy enables large-diameter structural applications, as demonstrated by durable trimmer lines that avoid the generation of persistent agricultural microplastic residues, thereby establishing a viable pathway toward high-performance, sustainable material alternatives.

Recently, wireless flexible strain sensors have attracted increasing attention in the fields of soft robotics, electronic skin, and health monitoring. Wireless signal transmission overcomes the wiring constraints and immobility of traditional sensors, while the widespread application of gel-based sensors is often limited by the inherent shortcomings of different materials, including low mechanical strength, poor conductivity, and inadequate cold resistance. To address this, this work synthesized the imidazole type poly (ionic liquid) (P(VIm-NH 2 [Tf 2 N])), and fabricated the self-healable, anti-freezing and conductive polyionic gels for use in wireless strain sensors. A key highlight is the direct conversion of a mixed solution of P(VIm-NH 2 [Tf 2 N]), poly (vinyl alcohol), and phytic acid into the polyionic gel at room temperature via supramolecular self-assembly driven by hydrogen bonds and electrostatic interactions, without external stimulation. These dynamic and reversible non-covalent bonds constructed a stable network, endowing the gel with a tensile strength of 705 kPa, an elongation at break of 600%, and 85% self-healing efficiency after 24 h at room temperature. The gel also maintained good flexibility and conductivity at −20 °C. Integrated with a Bluetooth module, the gel sensor enabled wireless monitoring of joint movement, handwriting, and speech recognition on mobile terminals. This work not only provides a new material platform for high-performance wireless strain sensors but also demonstrates an efficient, safe, and environmentally friendly supramolecular assembly strategy that is readily extendable to other functional polymer gels.

A novel PA-MIL-88A composite was designed for detection of phytic acid. • Structural optimization through controllable etching provides a new paradigm for the functionalization of MOF materials. • MIL-88A is water-degradable, and PA is natural plant extract. This strategy follows green analytical chemistry guidelines. • The sensor exhibits low LOD and a wide linear range. • The sensor exhibits excellent practical applicability in fruit juice. Ascorbic acid (AA) may cause adverse reactions when consumed in excess, posing conceivable wellness threats to humans. Consequently, accurate detection of AA content in food is crucial for ensuring food safety and safeguarding human health. This work successfully developed an electrochemical sensor based on phytic acid-etched modified MIL-88A (PA-MIL-88A) for detecting AA in juices. The electrochemical performance of the PA-MIL-88A composite was evaluated using cyclic voltammetry (CV) and differential pulse voltammetry (DPV). Experimental results indicate that the PA-MIL-88A composite exhibits excellent linearity for AA detection, with a linear range of 10 μM–2640 μM and the limit of detection as low as 2.68 μM. Furthermore, the sensor demonstrated excellent reproducibility, repeatability, and long-term stability. When detecting juice samples, it exhibited significant advantages in recovery rates and relative standard deviation (RSD) values. This work broadens the application of MIL-88A in electrochemical sensing and provides new insights for food detection. Download: Download high-res image (89KB) Download: Download full-size image

With the rapid increase in serious threats of electromagnetic interference, multilayer electromagnetic shielding composites (ML-ESCs) show broad prospects for preventing electromagnetic interference in green buildings, smart wearables, and aerospace. However, existing ML-ESCs suffer from poor cryogenic adhesion, non-flame-retardant substrates, and poor recyclability. Herein, we proposed an "interfacial cooperative adhesion factor system and dynamic reversible crosslinking" strategy to fabricate a multifunctional adhesive. The adhesive was constructed by employing a PTA dynamic covalent network as the backbone, wherein phytic acid (PA) and hexaphenoxycyclotriphosphazene (HPCTP) were introduced separately as hydrophilic and hydrophobic dynamic adhesion factors. The PA-HPCTP adhesion factor system endowed the adhesive with prominent multi-substrate adhesion adaptability, cryogenic adhesion durability, and flame-retardant performance. Moreover, the adhesive exhibited outstanding degradability in alkaline aqueous solution and efficient closed-loop recycling of TA and HPCTP, with both recovery rates exceeding 80%. Furthermore, the multifunctional adhesive was designed to construct diverse substrate-based sustainable ML-ESCs, including wood, textile fabric, glass, and carbon fiber, achieving the integration of high-efficiency electromagnetic shielding (up to 97.9 dB), extreme environmental tolerance, and multi-component closed-loop recycling of matrix monomers and substrates. This work provides new insights into the design of next-generation sustainable multifunctional polymer electromagnetic shielding composites.

Integrated PNCE enables dual-interface confinement and electrochemical sensing. • ZIF-8 confined growth regulates transport and enhances selective adsorption. • Sensitive TC detection with low LOD (0.22 ng mL −1 ) and high enrichment (>85%) in chicken samples. Nanochannel-based electrochemical sensors show great promise for food analysis, yet small-molecule detection remains challenging due to insufficient molecular recognition and limited interface utilization. Herein, we report a portable paper-based nanochannel electrode (PNCE) integrated with selective adsorption elements, in which nanoporous gold layers were modified on both sides of the nanochannels, and its application in small-molecule analysis was explored. ZIF-8 was controllably grown across the outer surfaces and internal fibrous pathways through counter-diffusion, narrowing the local transport pathways and restricting ion and probe transport. Combined with the strong adsorption capability of ZIF-8, the resulting ZIF-8/PNCE system directly captured target small molecules and suppressed the diffusion of electrochemical probes, thereby enabling sensitive small-molecule detection without requiring additional labeling or biological recognition elements. Based on the cooperative contribution of outer-surface interaction and inner-channel confinement, the ZIF-8/PNCE system achieved preferential adsorption and sensitive class-level detection of tetracycline-class antibiotics (TCs), with TC selected as a representative model analyte and a detection limit of 0.22 ng mL −1 , comparable to or even surpassing many sensing systems that rely on biological recognition probes. Moreover, electrostatic potential and binding-energy simulations further confirmed the strong interaction between TC and ZIF-8. Reliable recoveries (94.16–115.6%) in real chicken samples demonstrated the practical applicability of the platform. This work establishes a dual-interface confinement-regulated electrochemical sensing strategy for portable and label-free small-molecule analysis.

Although nanozymes are promising substitutes for natural enzymes due to their exceptional stability, low cost, and activity tunability, peroxidase (POD)-mimicking metal oxides like Co 3 O 4 are often limited by its moderate intrinsic activity. In this study, phosphorus-doped Co 3 O 4 nanofibers (P–Co 3 O 4 NFs) are synthesized via electrospinning and calcination. Optimizing the P incorporation level yields 21% P–Co 3 O 4 NFs with significantly enhanced peroxidase-like activity. Experimental and theoretical results reveal that P incorporation modulates the local electronic structure of Co sites, promoting H 2 O 2 adsorption, interfacial electron transfer, and Co 2+ /Co 3+ redox cycling, while the nanofibrous morphology ensures abundant accessible surfaces. A dual-mode colorimetric platform is constructed for ascorbic acid (AA) detection, yielding detection limits of 0.57 μM for solution-based assays and 1.66 μM for paper-based formats. Accurate total antioxidant capacity (TAC) determination in real samples (vitamin C tablets, fruits, beverages) is also demonstrated, with excellent recovery rates and assay time of only 140 s (solution) or 2 min (paper). This work provides mechanistic insights into heteroatom-doped nanozymes and offers a rapid, reliable sensing strategy for food quality monitoring.

The rational design and facile synthesis of non‑platinum carbon catalysts with high energy conversion efficiency remain a core challenge in electrocatalysis. To address this, we successfully constructed a unique shell-in-shell catalyst through a phytic acid (PA) etching and secondary pyrolysis strategy, designated as CZIF-PA-Fe 2 P/NC. In this process, PA not only drives the selective etching of cubic ZIF-8 nanocrystals but also serves as an in situ phosphorus source to induce the uniform nucleation of highly active Fe 2 P nanoparticles embedded in ZIF-derived N,P-codoped carbon nanoboxes. Consequently, the obtained CZIF-PA-Fe 2 P/NC catalyst achieves an excellent oxygen reduction reaction (ORR) half-wave potential of 0.914 V, and maintains a 96.73% current retention over a 30-h stability test. When assembled into zinc-air batteries, the device delivers a peak power density of 157.58 mW cm −2 , a specific capacity of 795.76 mAh g −1 , and long-term cycling stability surpassing that of 20 wt% Pt/C. Finally, density functional theory calculations reveal that the synergistic electronic modulation between the N,P-codoped carbon substrate and Fe 2 P promotes an upward shift of the Fe d -band center, thereby optimizing the adsorption of key *OOH intermediates and significantly reducing the energy barrier of the rate-determining step. This work establishes a precise morphology design and interface engineering paradigm for developing cost-effective, high-performance metal-organic framework-derived non-noble-metal carbon electrocatalysts for energy conversion and storage applications. The selective etching of phytic acid not only endows the material with abundant pore diameters to enhance mass transfer but also serves as an in-situ phosphorus source to promote the uniform nucleation of highly active Fe 2 P nanoparticles. By employing PA-induced etching, shell-in-shell carbon catalysts were successfully fabricated to exhibit satisfactory oxygen reduction.

With the continuous advancement of intelligent sensing technology, the growing demand for flexible electronic products has created valuable opportunities for the development of flexible pressure sensors. In this work, a polyurethane (PU) sponge was employed as a flexible substrate, where a coupling strategy was utilized to achieve surface modification of two-dimensional MXene nanosheets with phytic acid (PA), and a PA/MXene@PU sponge(PMP) sensor was successfully constructed through a self-assembly process. As a flame retardant and binder, PA effectively enhances the conductivity and mechanical properties of PMP. This sensor demonstrates high sensitivity (16.71 kPa⁻ ¹), a wide detection range (0-175 kPa), and stability exceeding 8000 cycles. It can effectively detect responses triggered by water droplets falling from a height of 2 cm and 20 mg NaCl aqueous solution impacts (0.01 N). Additionally, its excellent flame retardancy enables self-extinguishing within 20 seconds after ignition. Additionally, this paper integrates PMP with a gated recurrent unit convolutional neural network (MC-GRU) to achieve recognition and classification of six joints—ankles, wrists, fingers, throat, knees, and elbows—with a classification success rate of up to 99.83%. The results demonstrate the immense potential of PMP sponge sensors in physiological signal detection and human motion monitoring. This work establishes a solid foundation for the intelligent development of flexible pressure sensors in motion posture analysis while providing insights into the design of safe and environmentally friendly flexible sensors.
