Marine biofouling poses a major challenge to marine infrastructure and environmental sustainability. Inspired by the dynamic tentacle structures of corals and their exceptional self-cleaning capability, we developed a bioinspired UiO-66-TMG/PPy multifunctional antifouling coating with dynamic self-cleaning properties. Quaternary ammonium molecular brushes in the coating emulate the dynamic motion of coral tentacles, whilst photoelectrochemical coupling endows the coating with integrated bactericidal and self-cleaning functions. Cathodic polarization generates electrostatic repulsion and dynamic molecular motion as the primary antifouling barrier, whereas quaternary ammonium groups and photoelectrochemically generated reactive oxygen species (ROS) construct a secondary chemical barrier for bacterial inactivation and surface renewal. The synergistic effect of these two barriers affords outstanding antibacterial performance. Comprehensive characterization studies by XRD, FTIR, SEM, LSV, EIS, and Mott–Schottky analysis confirmed the successful construction and antibacterial action of the UiO-66-TMG/PPy coating. Under cathodic polarization (−1 V) and visible-light irradiation, the system achieved 98.7 ± 0.9% and 99.8 ± 0.1% inhibition against Escherichia coli and Staphylococcus aureus , respectively, demonstrating broad-spectrum antifouling capability. This work offers a new bioinspired route toward self-cleaning antifouling coatings for advanced marine applications.

Hydrogen energy is the core of future clean energy, and the study of hydrogen evolution reaction (HER) electrocatalytic mechanisms is essential for efficient production. The development of efficient and low-cost electrocatalysts is a key challenge in achieving ideal hydrogen generation. In this study, a Ni-BDC/TpPa-1 heterojunction material was prepared for the first time, which was converted into a derived heterojunction material (NiO@Ni/N-C) after high-temperature pyrolysis treatment, exhibiting excellent electrocatalytic activity in an alkaline solution. Without iR compensation, the overpotential of HER is only 83 mV at a current density of 10 mA·cm⁻². Compared with thermally decomposed Ni-BDC and TpPa-1 monomer, its electrocatalytic activity is improved by 158 and 435 mV, respectively, and it exhibits excellent stability over 100 h. The design of this novel material offers a new solution for enhancing the efficiency of transition-metal-based catalysts.

Microcapsule materials with selective mass transfer and mechanical stability are considered one of the potential adsorbents in the field of natural active molecules separation. Herein, a new kind of porous boronic acid affinity imprinted covalent organic framework (COFs) microcapsules (DR-MC@PDA@MIPs) via W/O type Pickering emulsion interface polymerization were fabricated for adsorption of naringin (NRG). During the emulsion interface assembly process, the dopamine-modified COF particles (BTCA-COFs@PDA) were stabilized at the water/oil phase interface, followed by the catalytic growth of COFs shell layers via multi-phase emulsion interface. For improve the specific adsorption amounts, the dendritic initiator (Y-Shape-(Br) 2 ) were modified onto the surface of COFs based MC. Ultimately, the DR-MC@PDA@MIPs were fabricated through atom transfer radical polymerization (ATRP). The prepared DR-MC@PDA@MIPs exhibited high enrichment amounts and good NRG selectivity under neutral conditions, with a rapid adsorption equilibrium rate (120 min) and an adsorption capacity for NRG (72.32 μmol/g). Furthermore, DR-MC@PDA@MIPs showed a higher imprinting factor (3.126) compared to non-imprinted adsorbents (DR-MC@PDA@NIPs). After seven separation cycles, the obtained DR-MC@PDA@MIPs exhibited good reusability, with an adsorption capacity of 92.38% of the first adsorption-elution cycle. The DR-MC@PDA@MIPs selectively purified crude NRG products to 94.51%. Therefore, this work provides a new boronic acid affinity COFs MC imprinted MC in the specific separation of targeted flavonoid molecules, overcoming some limitations of traditional microcapsule adsorbents and advancing further research and applications in the selective separation field.

This study addresses the urgent demand for simple and sensitive online gas monitoring technologies in the field of environmental safety by developing a high-performance cataluminescence (CTL) sensor based on oxygen-vacancy-rich microporous titanium dioxide (Ovm-TiO 2 ) for detecting trace isobutyraldehyde (IBL). The Ovm-TiO 2 material, synthesized via a two-step heating process combined with a KBH 4 treatment, features abundant oxygen vacancy defects on its surface, which are pivotal to enhancing sensor performance. Density functional theory (DFT) calculations unravel the surface-mediated mechanism, the oxygen vacancies serve as active sites, drastically enhancing the chemical adsorption and activation of O 2 on the Ovm-TiO 2 surface, which is the key to boosting the cataluminescence efficiency. The developed sensor exhibits outstanding detection performance for IBL, with a wide linear range (0.0100–5.00 mg/L, R 2 = 0.9997), a low detection limit (3 μg/L), and achieved recovery rates of 87.6%–107% with good reproducibility (relative standard deviation, RSD: 5.3%–9.0%) in practical sample analysis. This work not only provides a viable online monitoring solution for IBL but also elucidates the CTL enhancement mechanism at the atomic level, offering important theoretical foundations and practical insights for designing highly sensitive gas sensors.

Astringency, as a complex oral sensation, poses challenges for in-vitro detection and quantification due to the intricacy of its perception mechanism and the complexity of the astringent substances involved. To address this challenge, we developed a chitosan hydrogel-based sensor inspired by the human tongue. Mucins were embedded within the sensor to detect astringent polyphenols. When in contact with astringent phenolic compounds, the resulting precipitate aggregates entangle or block the pores, restricting ion conductivity within the sensor. Astringency detection is achieved using cyclic voltammetry. The tongue-inspired sensor can detect a wide range of tannic acid (1E −4 wt% - 5wt%), including the human sensory threshold for astringency, and construct a standard astringency quantification curve from the sensing data. It was demonstrated to revert the actual astringency sensing process by overall astringency detection and synergistic effect, simulating the in-vitro function of the tongue. In addition, the sensor provides insights for evaluating the optimal drinking time of open red wines based on astringency, offering a novel approach for wine astringency evaluation, demonstrating its potential for a variety of applications in the food and beverage industry.

Electrochemical detection of diquat (DQ) herbicide residue faces challenges in achieving the trade-off among selectivity, sensitivity, and stability in complex matrices. To overcome this, we reported a supramolecular electrochemical sensor (P6-TATR/AB/GCE) based on a newly synthesized electron-rich, hydrophobic pillar[6]arene-triazatruxene derivative (P6-TATR) integrated with acetylene black (AB). The sensor leverages the high conductivity and electrocatalytic activity of AB, while P6-TATR enables selective DQ recognition through synergistic electrostatic interaction, host-guest complexation, and competitive adsorption. This synergistic combination facilitates rapid DQ reduction at the electrode interface, enabling high-performance DQ monitoring. The proposed sensor demonstrated a low detection limit (0.784 nM), wide linear range (0.001–16.0 μM), and exceptional specificity against 100-fold interfering pesticides and ions. The sensor exhibited excellent reproducibility, with relative standard deviations (RSD) of 2.43% (intra-day), 2.94% (inter-day), and 3.08% (batch-to-batch). It also demonstrated robust long-term stability, retaining 90.4% of its initial signal after 150 days. Practical application in food and environmental samples yielded satisfactory recoveries (80.0%–116.0%) with RSD ≤ 7.4% ( n = 3), which were corroborated by High Performance Liquid Chromatography (HPLC) validation. The fabricated electrode outperforms existing DQ sensors in selectivity and stability, offering a new strategy for utilizing hydrophobic macrocycles in electrochemical analysis.

The direct dehydrogenation of lactic acid (LA) to pyruvic acid (PyA) presents a sustainable and atom-economical route for biomass valorization, yet it demands high-performance catalysts to achieve satisfactory activity and selectivity. While bimetallic catalysts often show enhanced performance, a deep understanding of the interfacial synergy remains a challenge. Herein, we report a series of CuCo bimetallic oxide catalysts that exhibit remarkable performance in the direct dehydrogenation of LA to PyA, significantly outperforming their monometallic counterparts. A combination of detailed catalyst characterization and kinetic analyses unravels the critical role of the CuCo oxide interface. It is demonstrated that the Co sites at the interface are primarily responsible for the activation and cleavage of the α-C-H and α-O-H bond in lactate, while the adjacent Cu species facilitate the stabilization of the reaction intermediate and the recombination and desorption of hydrogen. This synergistic cooperation at the interface not only promotes the reaction rate but also effectively suppresses undesired side reactions, such as decarbonylation and dehydration, thereby ensuring high selectivity to PyA. The optimized catalyst with a Cu/Co molar ratio of 3:2 demonstrated enhanced performance, delivering 73.4% LA conversion and 78.1% PyA selectivity at 300 °C, which surpasses the results obtained over the CuO 1-x /SiO₂-H400 benchmark under identical conditions. This work provides fundamental insights into the bifunctional mechanism of bimetallic oxides in direct dehydrogenation reactions, offering a strategic guideline for the rational design of efficient and selective catalytic systems for sustainable chemistry.

Fire safety remains a critical global challenge, as conventional fire protective materials focus on passive insulation/flame retardancy but lack active early-warning for incipient fires. Chitosan (CS)-based foams are promising for fire protection but suffer from inherent flammability, limiting practical use. Herein, CS-based foams composited with hydroxyapatite nanowires (HAP NWs) and phytate-melamine (PA/MEL) were fabricated via freeze-drying, forming an “active warning-passive protection” system. Structural characterizations confirmed uniform dispersion of HAP NWs and PA/MEL in CS matrix via hydrogen/ionic bonding. Thermogravimetric analysis revealed CS-HAP-10PA/MEL had 61.6% char residue at 750 °C (N 2 ), a 105.3% increase vs. pure CS. CS-HAP-10PA/MEL exhibited a limiting oxygen index (LOI) of 45.0% and a 76.3% lower peak heat release rate (pHRR) than pure CS, manifesting excellent flame retardancy. Fire warning tests indicated that CS-HAP-5PA/MEL triggered an alarm within 4.2 s (signal stable >60 s) upon exposure to flame and exhibited sensitive responsiveness at 60–200 °C (0.8 s response at 120 °C). A 6 mm-thick CS-HAP-5PA/MEL (36.6 mW/ (m . K)) sample reached only 61 °C surface temperature after 5 min at 120 °C (14.2 °C lower than pure CS), demonstrating good thermal insulation. This foam integrates warning, flame retardancy, and insulation, offering a novel strategy for intelligent fire protective materials.

The development of sustainable, high-performance alternatives to petroleum-derived plastics remains a critical challenge in materials science, especially under the global carbon neutrality goals. Herein, we reported a facile polymer-free strategy to fabricate high-strength, flexible, and biodegradable all-wood films (WFs) by inducing cell wall swelling within a delignified wood skeleton via simple alkaline treatments under varied conditions. Notably, by employing cold-alkali swelling (7 wt% NaOH at −6 °C for 24 h) followed with hot-pressing, the resultant WF-C24 with densified multilayered structure exhibited an ultra-high tensile strength (530.1 ± 28.3 MPa), superior toughness (26.9 MJ m −3 ), and a folding endurance of 7636 times, surpassing most of the reported wood films. They also demonstrated high transparency (71% at 600 nm), extremely low thermal conductivity (0.079 W m −1 K −1 ), good thermal stability, and remarkable wet tensile strength (~55 MPa), greatly exceeding typical cellulose-based films. The cold-alkali treatment provided extensive cell wall swelling combined with partial dissolution and regeneration which facilitate to form strong hydrogen bonding networks at cell wall interphases, leading to a “self-adhesive” wood film without any chemical adhesives. Besides, the WFs were fully recyclable and could be reproduced into cellulose papers with increased mechanical strength after repeated cycles, highlighting its sustainable recycling merits. Complete biodegradation within three months in natural soil condition further affirmed its environmental compatibility. These findings established a promising scalable and sustainability pathway for the cold-alkali-treatment wood films as bioplastic in advanced applications, such as heat insulating material, green packaging, and flexible electronics.

Poly(lactic acid) (PLA), a biodegradable polyester derived from renewable feedstocks, exhibits inherent brittleness, limited thermal stability, and uncontrolled degradability, which restricts its broader application as a sustainable biomaterial. Constructing robust and well-organized interfacial architectures offers an effective strategy to overcome these challenges. In this study, a rationally designed carbon quantum dots (CQDs)@titanium dioxide (TiO 2 ) nanonetwork was employed to reinforce PLA composites and elucidate how CQDs@TiO 2 modulates their structural features, interfacial characteristics, and overall properties. It was demonstrated that embedding CQDs@TiO 2 into PLA accelerated its degradation behavior in hydrolysis, phosphate-buffered saline (PBS) immersion, and soil burial tests. Meanwhile, the thermal resistance, overall thermal stability, and crystallization behavior of PLA were substantially enhanced due to the nucleation and thermal barrier effects of the CQDs@TiO 2 nanonetwork. Moreover, the uniform morphology and compatibility of CQDs@TiO 2 enabled homogeneous dispersion and effective stress transfer in PLA, leading to simultaneous enhancements in tensile modulus, strength, elongation, and toughness. Specifically, the tensile modulus, tensile strength, and elongation at break of PLA/CQDs@TiO 2 composites increased by 11%, 44%, and 107%, respectively, compared to pure PLA. This study provides an efficient and sustainable strategy for tailoring the mechanical, degradability, and thermal properties of PLA composites.

The sorption-enhanced steam gasification of biomass using CaO-based materials is considered a promising method for H 2 production, while the presence of H 2 S in the syngas results sulfur poisoning of the materials. In this work, DFT calculations were combined with experimental verification to elucidate the mechanism of H 2 S resistance and structural stability of Ce-doped CaO material. The theoretical results reveal that Ce-doping significantly modulates the surface electronic structure, and Ce-doped CaO surface exhibits less negative H 2 S adsorption energies and higher activation barriers for the initial dissociation steps compared with pristine CaO, thus the onset of the sulfidation reaction is inhibited. Furthermore, the formation of oxygen vacancies is energetically less favorable on Ce-doped CaO surfaces, which is a prerequisite for sulfidation reaction. Even under sulfur-poisoning conditions, the Ce-doped CaO retains superior CO 2 adsorption, and the adsorption of Ca 4 O 4 clusters demonstrates that a robust chemical anchoring effect was introduced by Ce-doping. Experimental results from 20 cycles of steam gasification of high‑sulfur Enteromorpha prolifera validate these theoretical findings, and Ce-doped CaO maintains high H 2 production and CO 2 capture performances with minimal sulfur-poisoning deactivation.

Background Emerging pollutants such as enrofloxacin (ENR) pose a serious threat to the ecosystem and public health due to their resistance to degradation and tendency to accumulate in the environment. Although existing antibiotic detection techniques have considerable application value, they suffer from high costs, complex operation procedures, or insufficient sensitivity. Therefore, there is an urgent need to develop a new detection method that is simple, rapid, low-cost, and environmentally friendly to efficiently monitor antibiotic pollution in environmental water bodies and safeguard public health. Results In this work, inspired by the superior catalytic activity of three-dimensional (3D) composite nanomaterials, we rationally designed and synthesized FeMoO 4 /Fe 7 S 8 nanosheet flower composites (3D FeMoO 4 /Fe 7 S 8 NSFs) as a novel peroxidase-mimicking nanozyme for the sensitive colorimetric detection of ENR. The as-synthesized NSFs exhibit outstanding intrinsic peroxidase-like activity, enabling their direct integration into a colorimetric sensing platform. Critically, the synergistic redox coupling between Mo 6+ /Mo 4+ and the Fe 2+ /Fe 3+ couple facilitates rapid electron transfer, thereby promoting efficient activation of peroxymonosulfate (PMS) to generate reactive oxygen species—including hydroxyl radicals (·OH), sulfate radicals (·SO 4 − ), singlet oxygen ( 1 O 2 ), and superoxide radicals (·O 2 − ), which collectively drive the oxidation of chromogenic substrates without requiring external enzymatic or chemical initiators. This mechanism underpins a robust, single-step colorimetric assay that overcomes key limitations of conventional methods, such as stringent temperature control, prolonged reaction times, and narrow pH operational windows, thus enabling rapid, reliable ENR quantification. The optimized sensing platform delivers a wide linear range (0.500–70.0 μM), a low detection limit (LOD) of 0.150 μM (S/N = 3), and a total assay time of only 5 min. Significance This system breaks through the limitations of traditional methods in terms of temperature, time, and pH conditions, and successfully generates free radicals and non-free radical active substances by activating PMS, thereby achieving rapid and efficient detection of antibiotics. This innovation provides a highly promising new strategy for the identification of fluoroquinolone (FQs) antibiotics and shows broad application prospects in the field of environmental pollutant detection and monitoring.
