A fluorescent switch nanoprobe based on boric acid-functionalized europium-based metal–organic framework (BA-Eu-MOF) integrated with a visual analysis platform assisted by smartphone was established for the sensitive detection of Hg 2+ and glutathione (GSH). The probe was fabricated with 5-boronoisophthalic acid as ligand and europium ions as metal node, which enables specific recognition of Hg 2+ through a transmetalation mechanism. Upon the introduction of Hg 2+ , the red fluorescence of the probe was quenched (“off” state). When GSH is added, because its thiol groups have a stronger binding affinity for Hg 2+ , it competitively extracts Hg 2+ from the BA-Eu-MOF/Hg 2+ complex, leading to fluorescence recovery (“on” state). Based on this “on-off-on” mode, the quantitative detection of Hg 2+ and GSH was achieved with detection limits of 0.67 nM and 0.087 µM. Furthermore, the intelligent sensing platform for quantitative detection of analytes was developed by utilizing a smartphone Color Grab App with detection limits of 9.57 µM and 2.32 µM, respectively. Both modes were successfully employed to the detection of Hg 2+ and GSH in actual samples with spiked recoveries ranging from 88.9% to 108.0%. Benefiting from the porous characteristics of MOF and the specific recognition capability of the boric acid group, the proposed probe exhibits notable advantages including facile preparation, operational simplicity, high sensitivity, and excellent selectivity. This study provides a facile, reliable and field-applicable novel detection strategy for environmental monitoring and the investigation of interactions between heavy metals and biomolecules.

Low-dimensional halide perovskites are promising candidates for solar-blind ultraviolet photodetectors. However, simultaneously achieving high photoresponsivity and low dark current remains challenging, due to the restricted transport and collection of photogenerated carriers caused by strong electronic localization. Here, guided by theoretical calculations of electronic structures, we report a solar-blind family of CsCdCl 3 perovskite single crystals, which features a 3D structural framework, delivering high carrier mobility of 7.54 cm 2 V −1 s −1 and a long carrier diffusion length of 6.96 μm. These achievements stem from the 3D electronic structure, enabling balanced carrier effective mass isosurfaces and enhanced band dispersion. CsCdCl 3 -based solar-blind photodetectors yield a photoresponsivity of 35.4 A W −1 and dark current of 1.0 × 10 −12 A. Moreover, the devices demonstrate a narrowband spectral response of only 20 nm with a spectral-rejection ratio of 1.96 × 10 3 , which enables spectral-selectivity flame detection, distinguishing various types of flames and showcasing potential in offshore oil flame monitoring.

Lignocellulosic plastic composites are widely used in many industries for their excellent mechanical strength and durability owing to the synergistic effect of lignocelluloses and polymers. However, the polymer content severely limits their recyclability and environmental sustainability. Here, a self-adhesive lignocellulosic composite is designed directly from forestry residue Eucommia ulmoides bark (EUB), which is rich in Eucommia ulmoides gum (EUG) and lignin. The fabrication consists of a two-step process of in situ epoxidation and self-adhesive technique. In situ epoxidation transformed the intrinsic EUG into an excellent viscoelastic epoxidized EUG (EEUG). The self-adhesive technique relies on hydrogen bonding reinforcement promoted by pressure-assisted densification and thermal-assisted flow of EEUG, and further enhanced by epoxy ring-opening. This process converts the raw materials into a fully natural self-adhesive composite without any additional polymers. The demonstrated composite exhibits enhanced mechanical strength, notable flexibility, high hydrophobicity (contact angle at 104.55°), remarkable water resistance, improved thermal stability, and biodegradability (52.96% mass loss in 5 months). In addition, the life cycle assessment reveals a carbon emission factor of 3.28 kg CO 2 eq/kg, which can be reduced to 1.56 kg CO 2 eq/kg under renewable-energy production. This work demonstrates a practical route for transforming forestry residue into high-value lignocellulosic materials and provides an environmentally benign alternative to conventional plastic-bonded systems.

Hovel screen–templated electrospinning method inspired by human dermal structure is proposed for flexible pressure sensors. • Electric–field–guided deposition and stress–localization/contact–area evolution sensing model were revealed. • The sensor achieves high sensitivity (54.44 kPa −1 ) and a broad detection range (0∼120 kPa). Flexible piezoresistive sensors are promising for wearable electronics and health monitoring, yet their advancement is often hindered by complex fabrication and limited structural tunability. Inspired by human skin dermal papillae, a silver nanoparticle/thermoplastic polyurethane (AgNPs/TPU) flexible piezoresistive sensor (ATFPS) with multilevel biomimetic microstructures is developed via screen–templated electrospinning and in situ silver nanoparticle reduction. Silver trifluoroacetate (C 2 AgF 3 O 2 ) is incorporated into the TPU solution, allowing uniform formation of AgNPs within the nanofibrous film. This approach yields a porous connective architecture reminiscent of the dermal papilla layer and establishes a three–dimensional conductive network analogous to skin neural terminals. A dermal papilla–like microprotrusion array is precisely patterned on the nanofibrous surface through electric–field–induced assembly at screen mesh template intersections. The formation mechanism of the microprotrusions and the sensing behavior of the AgNPs/TPU nanofibrous film (ATNF) are systematically analyzed via finite element modeling. Owing to its hierarchical structure, the sensor exhibits high sensitivity (54.44 kPa −1 over 0∼13.6 kPa) and a broad detection range up to 120 kPa, a response time of 360 ms, and stable performance over 1000 loading-unloading cycles. The ATFPS demonstrates excellent performance in human motion monitoring and signal transmission, providing a versatile strategy to enhance the functionality of flexible pressure sensors with significant theoretical and practical implications.

MIL-101(Fe)-modified E. prolifera biochar (MIL-BC) was successfully synthesized. • MIL-BC showed 89.14% enrofloxacin removal in mariculture wastewater. • MIL-BC showed over 86% removal efficiency at pH 3–5 and salinity 15–35‰. • Adsorption followed pseudo-second-order and Freundlich models. • Experimental and DFT results unraveled synergistic adsorption mechanisms. In this study, a metal-organic framework (MOF)-modified biochar (MIL-BC) was synthesized by decorating Enteromorpha prolifera -derived pristine biochar (BC) with MIL-101(Fe). Compared to BC, the adsorption performance of MIL-BC for enrofloxacin (ENR) in mariculture wastewater was significantly enhanced to 89.14%, and it maintained a high adsorption efficiency under varying solution pH and salinity conditions. Notably, this high adsorption efficiency remained practically stable across varying solution pH and salinity levels. Under acidic pH conditions, MIL-BC exhibited both acid resistance and high adsorption efficiency, achieving a peak adsorption removal of 97.77%. The adsorption kinetics and isotherms were well described by the pseudo-second-order and Freundlich models, respectively, indicating a heterogeneous multilayer adsorption process. The adsorption mechanisms primarily involved a synergistic combination of pore filling, π-π interactions, hydrogen bonding, complexation, electrostatic interactions, and hydrophobic interactions. Furthermore, density functional theory (DFT) calculations corroborated that the higher adsorption energy of MIL-BC fundamentally contributes to its enhanced adsorption performance. In the treatment of real seawater aquaculture wastewater, MIL-BC demonstrated exceptional adsorption performance, validating its tremendous potential as a high-performance adsorbent. Maintaining a removal efficiency of over 70% after five cycles. Consequently, this study offers a viable and highly promising technical pathway for the efficient removal of antibiotics from seawater aquaculture effluents.

Surface and interfacial regulation is critical for breathable wearable materials that require stable humidity-responsive electrical output together with auxiliary thermal functionality. Herein, we report a lysine-stabilized MXene/polyvinyl alcohol (PVA) electrospun nanofibrous membrane in which Ti₃C₂Tₓ MXene is incorporated into a porous and vapor-permeable fiber network. This design promotes interfacial compatibility between MXene and PVA, improves its dispersion within the polymer matrix, and preserves a breathable porous architecture that favors water-vapor transport and interfacial moisture uptake. The 2 mg/mL MXene-Lys/PVA exhibits a strong humidity-dependent electrical response, delivering a resistance response of 10,665 over 40–90% RH, and stable operation during repeated cycling and two months of storage. The sensing behavior is mainly associated with water-adsorption-mediated modulation of charge transport within the hydrated polymer/MXene interfacial network, while an additional low-frequency interfacial process emerges under high-humidity conditions. Beyond humidity sensing, the composite largely retains the vapor-transport capability of the porous PVA matrix and simultaneously provides effective photothermal conversion under light irradiation. A garment-mounted PET-ITO prototype further enables real-time wireless transmission of activity-associated humidity-responsive signals. These results show that L -lysine-assisted MXene integration in electrospun porous membranes provides a composition-tunable platform for humidity-responsive electrical readout and photothermal heating demonstrations.

Flexible wearable fabric-based strain sensors have attracted considerable attention for human motion monitoring and healthcare; however, their practical deployment remains severely limited by performance degradation in humid or wet environments and insufficient durability under cyclic mechanical loading. Herein, we presented a multifunctional wearable fabric (MWF) featuring a composite coating with hierarchical structure, that simultaneously delivered outstanding strain-sensing performance and robust superhydrophobicity via a facile dip-spray combined coating process. The synergistic effect of the inner MXene and outer fluorinated Fe 3 O 4 /MWCNTs (F-Fe 3 O 4 /MWCNTs), endowed the MWF with broad-range strain responsiveness (up to 200% strain) and outstanding waterproof functions originated from the superhydrophobic surface. Importantly, the copolymer used as continuous phase of the composite coating, substantially reinforcing interfacial bonding between the coating and the elastic fabric skeleton, resulting in remarkable long-term durability, maintaining stable electrical response over 3600 cyclic stretching/releasing tests (50% strain) while preserving waterproof functionality even under 100% tensile deformation. This work provided a new method to fabricate durable and high-performance flexible strain sensors with wide sensing range and environmental robustness, addressing the persistent challenge that has long hindered the translation of wearable electronic fabrics from laboratory prototypes to real-world applications.

Theory-experiment closed loop enables rational design of doped NiO electrochromics. • DFT screening identifies Y as the optimal dopant over La and Ce. • Y-doped NiO exhibits 50.6 % optical modulation and fast switching kinetics. • High coloration efficiency of 215.6 cm 2 ·C⁻ 1 is achieved experimentally. • Y-doped smart windows achieve 11.3 °C cooling, proving energy savings. Doping is an effective strategy to tailor NiO for high‑performance eletrochromic applications. In this work, first‑principles calculations reveal negative formation energies for Y (−5.83 eV) and La (−3.72 eV) in NiO, confirming spontaneous and stable doping. Experimentally, Y and La doping dramatically boost the charge storage capacity of crystalline NiO films. Most notably, at 500 nm, the Y‑doped (Y‑4) and La‑doped (La‑4) films achieve outstanding optical modulations of 50.6 % and 32.0 %, respectively. They far exceed the 8.3 % of undoped NiO‑400. The doped films also exhibit much faster switching kinetics: coloration/bleaching time of 4.2/6.1 s for Y‑doped and 8.0/4.3 s for La‑doped, compared to 7.0/6.5 s for undoped NiO. More importantly, they exhibit remarkably high coloration efficiencies of 215.6 and 262.0 cm 2 ·C −1 , respectively. After 1000 cycles, the Y‑doped film retains 88.0 % of its initial charge capacity, and the La‑doped film retains 90.7 %. Model house tests indicate their good thermal insulation performance for building applications. This strategy of integrating computational design with experimental validation provides a powerful and general approach to develop tailored doped‑NiO electrochromic materials and other advanced functional materials. Y(or La)-doped NiO electrochromic materials with high electrochromic properties was designed by first‑principles calculations and synthesis successfully.

Ag-doped bimetallic MOF-derived carbon nanorods made via coordination-pyrolysis. • Hierarchical porous carbon achieves an ultrahigh surface area of 2349 m 2 g −1 . • Ag-BMNR-2 delivers 364.7 F g −1 at 1 A g −1 , retaining 95.6% after 100,000 cycles. • As SIB anode, Ag-BMNR-2 shows 458.6 mAh g −1 with 90.1% retention over 700 cycles. • DFT reveals Ag lowers Na + diffusion barrier via an Ag-Ag-Ag electron network. The electrode-electrolyte interface engineering is paramount to advancing bifunctional porous carbon materials for zinc-hybrid supercapacitors (ZHSCs) and sodium-ion batteries (SIBs). Herein, a coordination-pyrolysis method is proposed to synthesize Ag-nanoparticle-decorated bimetallic MOF-derived carbon nanorods (Ag-BMNR-2), wherein the interfacial architecture is synergistically engineered through three mechanisms: (i) evenly dispersed Ag nanoparticles introduce electron-rich colloidal sites that reduce charge-transfer resistance and accelerate interfacial electron transport via a continuous Ag → Ag → Ag conductive network; (ii) chemical activation generates oxygen-rich surface functionalities (C O, C O, O H) that enhance electrolyte wettability and provide dipole-ion coupling sites for Na + coordination; and (iii) a hierarchical micro-mesoporous architecture maximizes ion-accessible interfacial area. Theoretical calculations and in/ex situ characterization confirm that Ag doping lowers the Na + diffusion barrier, strengthens adsorption affinity, and elevates the electronic density of states near the Fermi level. Benefiting from this synergistically engineered interface, Ag-BMNR-2 delivers 364.7 F g −1 at 1 A g −1 , retaining 95.6% capacity after 100,000 cycles in SCs, and achieves 458.6 mAh g −1 at 0.05 A g −1 with 90.1% capacity retention over 700 cycles in SIBs (ICE: 69.9%). This work establishes interface engineering of Ag-decorated hierarchical porous carbon as a versatile strategy for dual-functional energy storage materials.

Protoporphyrinogen oxidase (PPO) inhibitors have long
been considered
environmentally friendly herbicides due to their high efficacy and
low toxicity. However, we found that a widely used PPO inhibitor butafenacil
(BFA) and its transformation products (TPs) possessed exceptionally
high toxicity to some marine phytoplankton (96-h EC 50 of
BFA were 0.71 ± 0.08 μg/L and 1.3 ± 0.06 μg/L
for Skeletonema costatum and Chlorella sp., respectively). Bialgal culture experiments
revealed that BFA exposure enhanced the competitive advantage of Chlorella sp., triggering a shift in dominance from other
microalgae to Chlorella sp., which could alter the
community structure and potentially destabilize ecological imbalances
in marine environments. The degradation process of BFA in seawater
could be accelerated by Phaeodactylum tricornutum , as its half-life decreased from 7.5 to 3.3 days, and 16 (13 new)
TPs were identified by solid-phase extraction-liquid chromatography–high-resolution
tandem mass spectrometry. Using computational toxicology, TPs with
predicted toxicity comparable to parent BFA were isolated by preparative
liquid chromatography and subjected to algal toxicity tests. The semiquantitative
estimates indicated that the persistent high toxicity to microalgae
after BFA degradation was attributable to these toxic TPs on a BFA-equivalent
basis, underscoring the necessity to consider the potential environmental
risks posed by TPs.

Despite the rapid development of flexible piezoresistive pressure sensors in medical monitoring and human–computer interaction, traditional sensors fabricated with dense materials (e.g., elastomers) generally suffer from inadequate permeability and sweat trapping. This not only impairs wearing comfort but also may cause skin inflammation during long-term use. Moreover, most such sensors lack effective degradation pathways, exacerbating electronic-waste concerns, which are against the trends of sustainable development. To this end, we propose a co-electrospun approach for two precursor solutions, i.e., polydimethylsiloxane/polyamide (PDMS/PA) solution with/without carboxylated multi-walled carbon nanotube (c-MWCNT) additive. This approach produces a permeable and fully degradable nanofiber composite membrane, in which the PDMS/PA nanofibers form a nonconductive scaffold to support the conductive PDMS/PA/c-MWCNTs nanofibers with pressure-sensitive functionality. In addition to excellent and adjustable pressure-sensor performance, this device further possesses high air and moisture permeabilities (59.61 mm/s and 434.24 g·m –2 ·day –1 ) and waterproof capability, which maintains its sensing performance in the situation of human motion. The device is also fully degradable (in alcohol within 300 s) and recyclable, ensuring that the sensor conforms to the principles of sustainability-oriented process from production to disposal. Finally, we demonstrate the wide applications of this sensor in various scenarios, including human health monitoring, motion detection, and Morse code recognition.

MD simulations quantify intermolecular interactions governing microphase separation. • TPU/PLA blending resolve the rigidity-flexibility trade-off and reduce pore defects. • Component/interface tuning contributes to mixed failure mechanism of C/T 3.0 P 1 . • Process optimization induces composite multiscale dissipation to widen damping range. • Custom composite realizes reusable NS structure with novel reversible energy absorption. To develop lightweight reusable protective structures for aerospace and marine heavy equipment, single thermoplastics fail to balance stiffness and ductility. Here, a series of gradient Thermoplastic Polyurethane/Polylactic Acid (TPU/PLA) ratio (TPU, PLA, T 1.5 P 1 –T 3.5 P 1 ) systems and 3D printed continuous carbon fiber(CCF)-reinforced TPU/PLA composites are fabricated, and their molecular interactions, interfacial morphology, mechanical performance, and negative stiffness(NS) energy absorption are systematically investigated. Molecular dynamics(MD) simulations were conducted on CCF-reinforced resin systems to elucidate compatibility and mechanism across ratios within the 235–255 °C processing window. Combined with physical chemistry and morphological characterization, the intrinsic reasons for the interface bonding state, mechanical properties, and structural characteristics are also explained at the microscopic mechanism level. The X-ray Computed Tomography(XCT) shows that the volume porosity of C/PLA, C/TPU, C/T 2.0 P 1 , and C/T 3.0 P 1 is 0.126%, 0.411%, 1.261%, and 1.056%, respectively. Under the optimal process parameters, C/T 3.0 P 1 presents a unique brittle-ductile coupling fracture mode, with the comprehensive mechanical properties being the best, and its fracture elongation rate being 6.52 ± 0.21%. Its tensile strength(120.96 ± 12.30 MPa) and Young's modulus (4.88 ± 0.27GPa) are respectively 22.60% and 39.03% higher than those of C/TPU, and its bending strength(80.67 ± 6.00 MPa) and bending modulus(5.95 ± 0.04GPa) are 139.23% and 74.30% higher, respectively. The Dynamic Mechanical Analysis(DMA) test confirms that the multi-phase composite system builds multiple energy- dissipation paths, significantly expanding the wide-temperature damping stable interval. Finally, 3D-printed composite large-scale NS structures and periodic honeycomb were prepared, and impact and cyclic load-unload tests reveal C/T 3.0 P 1 achieves EA = 712.36 mJ(134.71%, 22.11% higher than C/TPU, C/PLA) and SEA = 0.239 mJ mm −3 , retaining 70.47% initial EA(501.99 mJ) after 10 cycles. TPU/PLA synergy overcomes the stiffness-ductility trade-off. This work fills the research gap of 3D-printed large-scale aerospace/marine protective components, reusable NS energy-absorbing structures.
