The residue of oxytetracycline hydrochloride (OTC) has emerged as a significant concern impacting both human health and the ecological environment. Photocatalysis has a good application prospect in the treatment of antibiotic pollution due to its advantages of lost cost, high efficiency and environmental friendliness, and the development of photocatalyst has become crucial for achieving effective photocatalytic degradation. The preparation of Z-scheme heterojunction is regarded as an effective strategy to enhance photocatalytic activity. Herein, double Z-scheme MIL-101(Fe)@AgI@TPA/TPB heterojunction materials were innovatively designed and successfully prepared. MIL-101(Fe)@AgI@TPA/TPB could achieve 95.09 % OTC removal efficiency under visible light irradiation in 70 min. The investigation of photoelectric properties and mechanisms revealed that MIL-101(Fe)@AgI@TPA/TPB had a broader range and enhanced ability for light absorption, along with a narrower band gap. It was determined that ·O 2 - and ·OH were the primary active species involved in the photocatalysis process. The mechanism of double Z-scheme heterojunction capable of facilitating efficient photocatalytic degradation was proposed, and the intermediate products and decomposition pathways of OTC in the photocatalytic degradation process were analyzed. This study provides innovative insights into practical application through the prepared double Z-scheme heterojunction photocatalyst aimed at remediating OTC contamination in water environments.

Nuclear matrix protein 22 (NMP22) is a well-recognized biomarker for bladder cancer; however, conventional detection methods often suffer from insufficient sensitivity, high-cost and time-consuming. In this work, a novel epitope molecularly imprinted polymer (EMIP)-based electrochemical biosensor was constructed for highly selective and sensitive determination of NMP22. The EMIP biosensor was fabricated by electro-polymerization with C-terminal dodecapeptide (GATPRAKGKAKH, named as epitope) of NMP22 as template and o -phenylenediamine ( o -PD) as functional monomer on the gold electrode (AuE) which was previously self-assembled with thiolated graphene (G-SH) and gold nanoparticles (AuNPs). The use of G-SH and AuNPs can supply synergistic effects for enhancing detection sensitivity and epitope imprinting of C-terminal dodecapeptide of NMP22 can provide high selectivity for NMP22 detection. To obtain the superior sensitivity, several experimental parameters affecting the performance of the EMIP electrochemical sensor were investigated, including the molar ratio of template to functional monomer, electropolymerization cycle, elution time and incubation time. Under the optimal experiment, this EMIP electrochemical biosensor exhibited a good linear relationship for NMP22 in the concentration range from 0.1 pg mL −1 to 1.0 μg mL −1 , with a limit of detection (LOD) of 0.077 pg mL −1 . Finally, the EMIP electrochemical biosensor was successfully used for the determination of NMP22 in human urine with the recovery rates ranging from 96.92 % to 100.88 %. Compared with conventional ELISA, the proposed EMIP biosensor displayed shorter detection time, improved reproducibility and comparable analytical reliability. These findings highlight that the developed EMIP biosensor holds strong potentials for early bladder cancer diagnosis and broader clinical applications.

Petroleum contamination poses a serious threat to human health and ecosystems worldwide, and microbially driven natural attenuation is an effective approach for accelerating hydrocarbon removal. Species of the genusRhodococcusare recognized for their ability to degrade long chain petroleum hydrocarbons. However, their physiological traits and degradation mechanisms under alkaline conditions remain insufficiently understood. In this study, soil samples were collected from the Dagang oilfield in Tianjin, China, andRhodococcussp. A17 was isolated as an active indigenous strain for genomic and physiological characterization under high pH petroleum degradation conditions. The results showed that strain A17 grew optimally at 30 °C, pH 9.0, and 2% salinity. Petroleum hydrocarbon degradation reached 67.8% within 72 h, with a degradation half life of 34.2 h. Genome sequencing identified 18 oxygenase related genes involved in alkane degradation, includingalkB, cytochrome P450 monooxygenases, and the long chain alkane monooxygenaseladA, together with four antibiotic resistance genes. Metabolite analysis suggested that alkane degradation might proceed via terminal and subterminal oxidation pathways. Overall, these findings indicate thatRhodococcussp. A17 exhibits multiple adaptive traits that support its potential application in the bioremediation of petroleum contaminated alkaline environments.

C7–C10 aromatics are indispensable components of aviation fuels to meet the swelling need for sealing rings in aero engines. Aromatics with a short and single substituent have weak low-temperature reactivity, yet this may be enhanced under a fuel blend environment. In this work, we investigated low-temperature oxidation chemistry of n-propylbenzene, a representative C9 aromatic in a blend with n-heptane, in a jet-stirred reactor. Time-of-flight molecular beam mass spectrometry using synchrotron vacuum ultraviolet radiation as a photon ionization source was used for product analysis and species identification. Thirty-six species were identified by comparison of measured photoionization efficiency curves and calculated species ionization energies, and six of them are key reaction intermediates of n-propylbenzene oxidation. Kinetic model simulations captured the measured mole fractions of reactants, main products, and intermediates with some discrepancies. Furthermore, many oxygenated aromatics are missing in the model, reflecting insufficient understanding of n-propylbenzene low-temperature chemistry. Low-temperature oxidation pathways were proposed based on molecular structures of reaction intermediates. This work explored low-temperature oxidation of n-propylbenzene under a fuel blend environment, which might be useful to unravel the low-temperature chemistry of C7–C10 aromatics in practical jet fuels.

Streaming potential generation through water flow in porous media represents an ancient and ubiquitous geophysical phenomenon. For centuries, this process has been regarded as merely a process of charge redistribution without involving any redox reactions. By using NO3– reduction as a model reaction, this study demonstrated for the first time that water flow drives abiotic denitrification associated with streaming potential generation. The nitrate (NO3–) reduction rate reached 10.6 μmol·L–1·d–1, which is comparable to that of FeS-driven chemical NO3– reduction (75.0–380 μmol·L–1·d–1) and significantly higher than that of photochemistry-driven NO3– reduction (0.1–1 μmol·L–1·d–1). Through monitoring of nitrogenous products and 15NO3– isotopic experiments, we showed that NO3– was selectively reduced to nitrogen (99%) via nitrite and nitrous oxide, confirming a denitrification process. Electron paramagnetic resonance (ESR) spectroscopy using DMPO as the probe detected the generation of hydrogen radicals (H•), which served as the reducing force for NO3– reduction. Using TEMPO as the electron probe, linear electron production was observed with an electron efficiency of 6.3% for NO3– denitrification. Moreover, H218O isotope experiments demonstrated that water oxidation is the ultimate electron source for NO3– reduction, indicating a chemical-free NO3– reduction process. An electric field strength of approximately 106 V/cm was detected using surface-enhanced Raman scattering, providing evidence of a strong interfacial electric field (IEF)-induced electron transfer process during water flow. This work reveals ubiquitous but long-overlooked redox reactions associated with streaming potentials. Water-flow-driven denitrification also highlights a newly identified abiotic NO3– elimination pathway, suggesting potent chemical-free NO3– remediation strategies.

Degree of circular polarization (DOCP) of reflected light is an intriguing optical phenomenon of chiral photonic materials; however, it remains underexploited. This is especially the case with cellulose nanocrystals (CNCs), despite the fact that their angle-dependent structural color has been overwhelmingly attended to. Herein, CNC-based chiral photonic materials capable of dual actuation are constructed by vacuum-assisted self-assembly. Leveraging femtosecond laser machining, complex structural color 3D shapes, and crawling robotic devices are produced from these materials. The incident angle-incident lasing wavelength-reflected light DOCP correlation and DOCP-based ternary code are established, based on which a secure and efficient robotic information transmission strategy is presented, where a message is simply synthesized from structural color photos using a single-use key and the encryption security increases with photo numbers by power law. Our work unleashes the hidden potential of CNC-based soft actuators and enables them for secure and efficient robotic data transmission.

Metal–organic frameworks (MOFs) have received widespread attention in various energy related applications due to their unique structural characteristics. Nevertheless, the inherent low electronic conductivity of MOFs is a major limitation for their competitive activity. Herein, we synthesized a self-standing NiFe MOF@Ni3S2 core–shell hierarchical heterostructure through using Ni3S2 grown on nickel foam (NF) as a semisacrificial template, in which the highly conductive Ni3S2 nanosheets core endows the hybrid with rapid charge transfer capability, and the bimetallic NiFe MOF nanosheets provide abundant exposed active sites. Benefiting from the structural and compositional advantages, the enhanced electrocatalytic activity of the as-obtained NiFe MOF@Ni3S2/NF has been achieved toward alkaline oxygen evolution reaction (OER). As a result, the NiFe MOF@Ni3S2/NF only requires overpotentials of 177 and 219 mV to yield OER current densities of 10 and 100 mA cm–2, respectively, and exhibits a very small Tafel slope of 24.1 mV dec–1 and high durability, making it among the most efficient earth-abundant OER catalysts. This study will inspire further construction of MOF-based nanocomposites for applications in electrochemical renewable energy systems.

Noise ranks as the world’s second-largest environmental risk factor according to the WHO. The simultaneous achievement of ultrabroadband and perfect or near-perfect noise absorption is a quite significant yet long-standing challenge. Here, we propose a “gradient pore circulation (GPC)” strategy for building a hierarchical ordered architecture of green aerogels by using highly active microfibers precisely dissociated from a wood S2 sublayer as basic units. The aerogels comprise anisotropic, parallelly layered microchannels enriched with multilevel pores within each layer, alongside abundant spring-shaped strips bridging these adjacent layers. Under the “GPC” strategy, the soundwaves effortlessly enter the parallelly layered microchannels possessing moderate flow resistance, while the synergy of long microchannels, multilevel pores, and abundant interlayer strips creates plentiful closed loops, fostering a repetitive cyclic reflection–friction–dissipation of soundwaves. Under these synergies, the aerogels achieve near-perfect acoustic absorption properties, with a sound-absorption coefficient (SAC) of 0.95 to 1 across an ultrabroad frequency range of 520 to 6300 Hz and a superb noise-reduction coefficient of 0.82, the highest recorded to date. More significantly, the aerogels retain excellent sound absorption (SAC > 0.85) even under extreme temperatures (−196 to +80 °C), and high humidities (up to 98%) and salt spray environments with mild modifications. Moreover, the aerogels are biodegradable, superelastic, and have strong compression fatigue resistance over 1000 cycles, manifesting great potential as sustainable sound absorption materials for diverse applications.

Flexible actuators, as core components of soft robots, have attracted considerable interest for converting external energy into mechanical motion. However, most existing actuators still exhibit limitations in multistimulus responsiveness, shape programmability, and mechanical stability, which severely restrict their application in complex environments. Herein, we developed a multiresponsive, programmable bilayer actuator based on MXene/cellulose nanofibers (MXC) composite film and biaxially oriented polypropylene (BOPP) tape. By leveraging the hygroscopic, photothermal, and electrothermal properties of the MXC layer alongside the thermal expansion of the BOPP layer, the actuator achieves reversible, large-angle, and highly stable bending deformations under humidity, light, and electrical actuation. By combining pattern design and macroscopic reassembly strategy, various actuators that can realize programmable 2D-to-3D complex deformations have been demonstrated. As proof-of-concept applications, we have developed several soft robots, including a biomimetic leaf, a multiresponsive smart gripper, and a biomimetic crawling beetle robot, which hold significant potential for advancing next-generation soft robotics.

Thermally conductive and electrically insulating polymer composites exhibit significant advantages in thermal management applications, which are attributed to their broad applicability, facile processing characteristics, and favorable cost-performance ratio. In this study, composites with the above performance are achieved by incorporating hydroxylated boron nitride nanosheets (fBNNSs) into the poly(ether ether ketone) (PEEK) matrix. Additionally, carboxylated multiwalled carbon nanotubes (fMWCNTs) were introduced to bridge the dispersed fBNNSs, thereby significantly enhancing the thermal conductivity of the composite while preserving its electrical insulating properties. To construct a continuous thermally conductive network, the electrospinning technique is utilized to align the fillers within the matrix. In order to overcome the difficulty caused by PEEK insolubility for use in the electrospinning process, soluble poly(aryl ether ketone imine) (PEEKt) was synthesized to facilitate the formation of a nanofiber membrane, which undergoes an acidolysis treatment and successfully regenerates the PEEK main chain structure while preserving the fiber morphology intact. After hot-pressing molding, the thermal conductivity (λ) of the composite reaches 6.02 W/(m·K), and the electrical insulating performance remains 1016 Ω·cm orders of magnitude when the weight ratio of fBNNSs to fMWCNT is 25:1. This study provides an innovative methodology for the preparation of a PEEK-based composite with high thermal conductivity and electrical insulation properties utilizing electrospinning followed by hot-pressing.

Although traditional graphene-based absorbing materials exhibit excellent dielectric loss properties, they are prone to agglomeration and possess excessively high electrical conductivity, which can cause impedance mismatch and consequently degrade absorption performance. These limitations significantly constrain their application in electromagnetic wave absorption. Therefore, integrating graphene with other materials to reduce agglomeration, lower electrical conductivity, and enhance absorption performance is of great importance. This study proposes a low-solvent nanofluid composite strategy, where graphene oxide-coated silicon carbide (GO/SiC) serves as the core structure, with 3-Glycidoxypropyltrimethoxysilane (KH560) and Jeffamine M2070 (M2070) functioning as the corona and halo layers, respectively. Compared with graphene, GO induces additional surface defects, thereby enhancing dipole polarization; while SiC mitigates the excessive electrical conductivity of graphene, optimizes impedance matching, and creates heterogeneous interfaces to promote multiple internal reflections and interfacial effects. Moreover, the synergistic effect between KH560 and M2070 effectively suppresses GO agglomeration, enhances material fluidity, and facilitates interface heterogeneity. Compared with previously reported SiC-based composites (e.g., MWCNT/SiC with RLmin = −38.7 dB and EAB = 4.6 GHz), the GO/SiC-M2070 series composites in this study exhibit superior microwave absorption performance, with a minimum reflection loss (RLmin) as low as −47.0 dB and a maximum effective absorption bandwidth (EAB) of 7.94 GHz. This provides insights for the design of next-generation broadband and high-performance microwave absorbing materials.

Uncontrolled proton activity in aqueous electrolytes triggers detrimental side reactions that compromise the stability of zinc (Zn) metal anodes. To address this challenge, we propose a full-process proton regulation strategy enabled by the unique β-1,4-glycosidic framework of chitosan oligosaccharide (COS). The rigid COS backbone effectively constrains proton generation and transport in the electrolyte, while its preferential interfacial adsorption constructs an ultrathin molecular barrier that inhibits proton consumption at the Zn surface. This dual-function molecular architecture synergistically realizes “generation-transport-consumption” proton regulation, thereby delivering exceptional electrochemical performance: long-term cycling stability over 8,000 h in Zn||Zn symmetric cells, an average Coulombic efficiency of 99.84% over 2,300 cycles in Zn||Cu cells, and superior cycling stability for more than 2,000 cycles at 2 A g–1 in Zn||MnO2 full cells. This work reveals glycosidic frameworks as a universal and transferable design principle for aqueous batteries, shifting electrolyte design from functional group-centric optimization to framework-enabled regulation toward sustainable, high-performance energy storage.
