The benzodiazepine diazepam is an emerging environmental contaminant that poses a potential threat to ecosystems and human health. However, there are knowledge gaps regarding tissue-specific accumulation and biotransformation, and the potential toxicity of diazepam in economically important fish at environmental concentrations. This study explored the tissue distribution and accumulation of diazepam and its metabolites in juvenile yellowbelly pufferfish after 35 days of exposure to environmentally relevant concentrations (2, 20, and 100 ng/L). Additionally, changes in oxidative stress markers and neurotransmitter levels were analyzed during a 35-day exposure period and a 7-day recovery period. Our results showed that after 35-day exposure, diazepam exhibited the highest accumulation in the liver tissue of yellowbelly pufferfish, followed by the brain tissue. Moreover, biotransformation occurred in vivo , including demethylation and hydroxylation. Significant differences in superoxide dismutase, catalase, and glutathione peroxidase enzyme activity between the medium and high-level treatment groups reflected the compensatory effect of antioxidant defenses, while the unchanged malondialdehyde levels indicated their strong antioxidant stress capacity. Furthermore, the down-regulation of key neurotransmitters (glutamate, γ-aminobutyric acid, dopamine, 5-hydroxytryptamine, and norepinephrine) in brain tissues during the exposure period and recovery period confirms the high potential for neurotoxicity at environmental concentrations of diazepam. These results provide fundamental support for an in-depth understanding of the tissue-specific accumulation and potential toxicity of diazepam and its metabolites to marine organisms.

As an effective soil amendment, biochar can reduce the adverse effects and environmental impacts of neonicotinoid pesticides. Rhamnolipid, an active and common biosurfactant in soil systems, may alter the co-transport behaviors of biochar colloids and pesticides. Nevertheless, biosurfactant-mediated changes in pesticide mobility in soils affected by biochar colloids are currently lacking. Herein, the single or combined effects of biochar colloids and rhamnolipid on the transport properties of dinotefuran (DTF, a typical neonicotinoid pesticide) in soil matrix were investigated. When the influents contained biochar colloids, the DTF transport was reduced, primarily via colloid-associated DTF deposition and pesticide bound to the deposited colloids on porous media surfaces. Meanwhile, rhamnolipid also restrained DTF mobility because of its bridging effect (i.e., this biosurfactant mediated DTF-soil binding through molecular bridging). However, rhamnolipid notably diminished the suppressed influences of biochar colloids on DTF transport because of the decrease of colloid-associated DTF retention and the high mobility of free DTF. Moreover, the degree of rhamnolipid's weakened effects was related to the solution pH values (i.e., the influences declined as the pH values increased). Because rhamnolipid exhibited greater inhibition effects on the binding abilities of colloids to pesticide molecules under lower pH conditions (pH 5.0), leading to more free DTF mobility. The results underscore the critical roles of ubiquitous biosurfactants in the fate and risks of pesticides when biochar is used as an amendment for contaminated soil.

Chiral enantiomers exhibit distinct pharmacological and pharmacokinetic properties, making the precise detection of chiral components crucial to avoid harmful effects on the human body. Terahertz (THz) spectroscopy, which resolves molecular structures by detecting intra- and intermolecular vibrational modes, has been enhanced through the integration with metasurfaces, extending its applications in biomedical and security detection. However, current methods face significant challenges in trace analysis and broadband detection of analytes. Here, we propose a novel metasurface-based approach for detecting molecular broadband fingerprint spectra, combining the simplicity of state-of-the-art THz angle-scanning methods with the specificity of molecular fingerprinting. Specifically, we designed a guided mode resonance (GMR) metasurface capable of providing localized electromagnetic field enhancement and continuous spectra between 0.95 and 1.45 THz. We demonstrate the enhanced detection of intrinsic absorption features of glutamic acid enantiomers by correlating the molecular absorption spectra with the reflectance spectra at each incident angle. This angle-scanning approach simplifies the identification process and spectroscopic system, offering the potential for miniaturization and field deployment of THz spectroscopic devices for molecular detection.

s The practical application of transition metal phosphides (TMPs) in lithium-ion batteries (LIBs) has been severely hindered, primarily due to slow reaction kinetics and significant volume changes. While optimizing nanostructures could mitigate these issues, it remains a considerable challenge. Herein, NiFeP/C@rGO composites were synthesized through a multi-step protocol, involving coprecipitation, electrostatic self-assembly, and low-temperature phosphatization. The composites feature reduced graphene oxide (rGO)-coated nano-cubic frameworks derived from Prussian blue analogues (Ni/Fe-PBA), where the rGO carbon layer serves dual functions: effectively buffering volume expansion during charge/discharge cycles and enhancing overall electrical conductivity. Furthermore, the bimetallic heterostructure synergistically optimizes electrochemical performance. Remarkably, the optimized NiFeP/C@rGO-21 electrode demonstrates outstanding cycling stability, maintaining a specific capacity of 530.4 mAh g −1 after 300 cycles at a high current density of 1000 mA g −1 .

Swelling of membranes can lead to reduced mechanical strength and deformation of the pore structure. The traditional cross-linking modification method still suffers from the disadvantages of solvent residue and complex operations. This study proposed a stability-enhanced sulfonated polysulfone (SPSF)-polyethyleneimine (PEI)/polyethersulfone (PES) composite membrane through a simple and effective strategy using a two-nozzle electrospinning technique. The SPSF/PES and PEI/PES jets interweave in the electric field via electrostatic interactions or hydrogen bonding to form a composite membrane, which demonstrated a tensile strength increase of over 85.2 % alongside a swelling ratio reduction exceeding 51.4 % compared with the PEI/PES membrane. The adsorption of SPSF-PEI/PES composite membranes for Acid Fuchsin follows a pseudo-first-order kinetic model. Besides, the adsorption capacities of the optimal composite membrane for Acid Orange 7 (AO7), Acid Fuchsin (AF), Congo Red (RB), and Methyl Blue (MB) reached 267.9, 320.2, 428.4, and 439.5 mg/g, respectively. This study proposed a simple and effective strategy for preparing electrospun membranes with improved swelling properties and high-efficiency anionic dye adsorption.

Solid Oxide Electrolysis Cell (SOEC) is an effective technology for converting carbon dioxide (CO 2 ) into valuable products, like carbon monoxide (CO) and oxygen (O 2 ) using renewable electricity. An ideal electrode material for SOECs should possess fast electrode kinetics, high energy efficiency, and low cost. However, poor CO 2 adsorption at the cathode limits practical application, making design of highly active and durable cathodes a significant challenge. This study introduces a novel Ni-basalt cathode for CO 2 -SOECs. The Ni-basalt composite cathode, is prepared by pressing method and reduction treatment, demonstrates a high concentration of oxygen vacancies, which creates more active sites that enhance CO 2 adsorption and reduction performance. The resulting SOEC demonstrates a high current density (480 mA/cm 2 ), a low polarization resistance (1.91 Ω cm 2 ) at 1.6 V and at 800 °C, and high CO production (7.45 ml min −1 cm −2 ) with a faradaic efficiency greater than 90 %, indicating its potential for advancing CO 2 conversion.

Multifunctional composite catalysts show significant potential for enhancing the thermal decomposition and combustion of energetic materials. However, their synergistic mechanisms remain unclear. In this work, we prepared a 3D macroporous (3DM) CuO/ZnO catalyst via PMMA template calcination and combined it with Ti 3 C 2 T x MXene through electrostatic assembly, to form a 3DM CuO/ZnO-Ti 3 C 2 T x heterogeneous catalyst with uniform morphology and high conductivity. Results show that 3DM CuO/ZnO-Ti 3 C 2 T x has a good catalytic effect on TKX-50, which can advance the decomposition peak from 246 to 208 ℃, increase the heat release from 730 to 1106 J/g and boost combustion time from 560 to 790 ms, improve the flame temperature from 773 to 1109 ℃. By combining LAMMPS, materials studio software and TG-MS-IR analysis, the catalytic mechanism of 3DM material on the thermal decomposition of TKX-50 was deeply explored. 3DM materials can adsorb hydroxylamine molecule, accelerate the H + transfer process, achieve rapid exchange of H and OH, and realize the rapid and concentrated release of gas, thereby promoting the decomposition process of TKX-50. Consequently, the construction of composite catalysts with synergy can start from the perspective of forming more heterostructures, which provides better theoretical support for future research on composite catalysts.

MXene with brilliant conductivity, adjustable electromagnetic parameters and impressive electromagnetic wave (EMW) dissipation capacity has aroused considerable interest in EMW absorption field. Nevertheless, the poor EMW absorption performance caused by the serious impedance mismatching severely constrains its application in practice. In this regard, the NiCoMoS/MXene hybrids with abundant heterointerfaces were constructed through a facile electrostatic self-assembly strategy. The integration of NiCoMoS and MXene not only remarkably improves impedance matching, but also dramatically enhances the interfacial polarization. The synergistic effect of improved impedance matching and strong attenuation capacity originated from multiple loss mechanisms endows the resultant hybrids with outstanding EMW absorption performance. The NCMM3 hybrid realizes an optimal reflection loss of −56.4 dB at 12.66 GHz under a thin thickness of only 2.61 mm and a wide effective absorption bandwidth of 8.2 GHz (9.8–18.0 GHz), covering the majority of X band and the whole Ku band. Additionally, the remarkable stealth performance of the prepared NCMM hybrids used in practice is intuitively confirmed by the radar-scattering cross section simulation. This work provides a reliable approach for designing and fabricating highly efficient MXene-based EMW absorption materials with multiple components and ingenious structure.

Photocatalytic degradation is a promising method for alleviating water pollution by utilizing solar energy and molecular oxygen as an oxidant. In this study, we synthesized an n-p type Cu 2 O/SnS 2 composite with an S-scheme heterojunction structure and investigated its photocatalytic degradation performance on methyl orange dye. Nano-cubic Cu 2 O particles are uniformly distributed on SnS 2 nanoflowers, forming a tight S-scheme heterojunction that facilitates rapid separation and transfer of photogenerated carriers. Superoxide radicals and holes play crucial roles in the photocatalytic degradation of methyl orange. Oxygen adsorption experiments reveal the adsorption behavior on the S-scheme heterojunction surface and its impact on photocatalytic performance. At a copper-to-tin ratio of 3:1, the Cu 2 O/SnS 2 composite achieved the highest catalytic activity under xenon lamp irradiation, with a methyl orange degradation rate of 97 % within 75 min and over 93 % after four cycles. The first-order reaction rate constant was significantly higher than those of Cu 2 O and SnS 2 . This study provides valuable insights into the design of efficient photocatalytic materials for environmental applications.

Radioiodine anions (I and IO 3 ) pose a serious threat to the environment and human health due to their high radioactivity and solubility. Therefore, it is important to develop efficient and economical adsorbent materials for radioiodine anions. In this work, combined with the excellent properties of chitosan (CS) and (3-acrylamidopropyl) trimethylammonium chloride (AMPTAC), a novel interpenetrating network hydrogel CS@AMPTAC was synthesized to improve the adsorption efficiency of CS hydrogel for I and IO 3 . Due to the electrostatic interaction and anion exchange ability of the quaternary ammonium group (−N + (CH 3 ) 3 Cl⁻), the introduction of AMPTAC constructs a more complex and effective adsorption sites for CS@AMPTAC. Combined with the protonated amino group (−NH 3 + ) in CS, the CS@AMPTAC showed better adsorption efficiency and anti-interference performance than CS. The CS@AMPTAC hydrogel shows excellent adsorption performance over a wide pH range (pH 2–11), which overcomes the sensitivity of traditional adsorbents to pH. Meanwhile, the maximum adsorption capacities of CS@AMPTAC for I and IO 3 are 359.9 mg/g and 312.64 mg/g, respectively, which exhibits remarkable enhancements of 246.26 mg/g and 267.34 mg/g compared to CS. In addition, based on the synergistic adsorption mechanism and the hydrophilicity of CS@AMPTAC, the hydrogel can reach adsorption equilibrium within 30 min. The synergic strategy shows great potential for application in the treatment of radioiodine anions.

During the catalytic growth of CNTs, the ordered arrangement of catalysts is critical for maintaining their array structure. Unlike mechanisms that suppress nanoparticle migration via high catalyst density to enforce CNTs array growth, this study proposes a strategy involving surface engineering and nanoparticle nucleation to construct Mo-Fe-S/Al 2 O 3 heterogeneous ternary catalysts. This method modulates the electronic density of Fe sites to activate catalytic activity while constructing Mo-Fe-S sites on the catalyst surface to catalyze the growth of a "C network" (carbon pillars and CNTs), thereby forming CNTs arrays. On one hand, S and Mo weaken the interfacial interactions between Al 2 O 3 and inactive FeO x nanoparticles, promoting active particle nucleation; on the other hand, the "C network" grown via Mo-Fe-S constitutes the top part of the CNTs arrays, confining the internal nanoparticles (NPs) to enable vertically aligned growth of CNTs. Characterizations reveal NPs with diameters of ∼20 nm and symmetrically grown CNTs arrays with average diameters and heights of 18.21 nm and 10.10μm, respectively. This work provides an approach for the catalytic growth of CNTs arrays using supported catalysts, by forming a "C network" to suppress the entanglement of NPs during the catalytic growth of CNTs, thereby forming the CNTs array structure.
