In this study, a novel CoZnAl-LDH coating was synthesized in-situ on anodized aluminum through a hydrothermal method without introducing trivalent metal salts. Subsequently, a vanadate-intercalated LDH-VS coating was fabricated via ion exchange and hexadecyltrimethoxysilane (HDTMS) self-assembly, which integrated long-term corrosion resistance, friction reduction, and superhydrophobicity into a single coating. The morphology and structure of the coatings were investigated using SEM, EDS, XRD, FT-IR, and XPS. The coating performance was evaluated through scratch tests, contact angle, electrochemical, and friction wear tests. The results demonstrated that the contact angle of the LDH-VS increased from 26° to 154° and remained above 120° even after prolonged immersion, exhibiting outstanding self-cleaning and antifouling properties. After 28 days of immersion in 3.5 wt% NaCl solution, the corrosion current density of LDH-VS decreased by four orders of magnitude to 8.09 × 10 −9 A·cm −2 compared to bare aluminum alloy and the microstructure remained intact, indicating excellent long-term corrosion resistance. Friction tests confirmed the superior friction reduction of the modified coating, with the average friction coefficient of LDH-VS decreasing to 0.28, significantly lower than that of the aluminum alloy. Scratch tests also verified the coating's excellent adhesion strength. This study provides new insights into the development and application of LDH in superhydrophobicity, long-term corrosion protection, and wear resistance.

Fenton-like oxidation is often hampered by high energy barriers, uncontrolled oxidation pathways, and inefficient reactive oxygen species (ROS) utilization. Here, we report an energy-driven confined catalytic nanoreactor that leverages the in-situ confinement energy generated within nanopores to fundamentally regulate degradation thermodynamics. Taking sulfamethoxazole (SMX) as a model contaminant, the confined nanoreactor exhibited a 22.11-fold higher kinetic constant (0.157 min −1 ) and 40 % enhanced mineralization efficiency compared with its non-confined system. The imprinting channel of confined nanoreactor enabled selective adsorption of SMX within the nanochannel, inducing pronounced confinement effects. The resulting confinement energy triggered a low-entropy degradation pathway (ΔS reduced by 3.2 × 10 3 -fold), which broke thermal equilibrium constraints and redirected SMX oxidation along a low-energy-barrier route. The in-situ confinement-induced low-entropy reaction not only accelerated pollutant degradation but also improved ROS conversion efficiency. This study demonstrated a green and sustainable approach to overcome the intrinsic efficiency bottleneck of Fenton-like processes and provide a new perspective on exploiting nanoconfinement effects for environmental remediation.

The activation of the lattice oxygen oxidation mechanism is vital for enhancing oxygen evolution reaction (OER) performance as it enables direct O–O bond formation, avoiding the *OOH formation. Compared with the conventional adsorbate evolution mechanism (AEM), the lattice oxygen-mediated mechanism (LOM) can break the theoretical limit of conventional adsorbate-based scaling relations and enhance the oxygen evolution reaction kinetics. Thus, there is an urgent need for an efficient strategy for designing OER electrocatalysts based on LOM. The O p band center is employed as descriptor in conjunction with machine learning to facilitate the activation of lattice oxygen. The descriptor can accelerate the catalyst design process as it circumvents the need for complex intermediate calculations. According to predictions, the Fe-Co 3 O 4 catalyst exhibits OER performance comparable to that of noble metal catalysts. The Fe-Co 3 O 4 catalyst achieves a low overpotential of 258 mV at 20 mA cm -2 in 0.5 M H 2 SO 4 , attributed to the shift in catalytic mechanism from AEM to LOM.The incorporation of Fe effectively induces an upshift in the O p band center and weakens the Co–O bond, thereby promoting direct O–O coupling for O 2 generation and consequently reducing the OER overpotential. Our study introduces a method to activate the lattice oxygen of metal oxide electrocatalysts, holding substantial promise for enhancing large-scale hydrogen production.

The production of biodiesel from renewable feedstocks through energy-efficient processes remains a pressing challenge. Pickering emulsions, stabilized by solid particles, have emerged as a promising approach to enhance biodiesel production. This study presents the synthesis of dumbbell-shaped Janus polymer nanoparticles (DS-JPNs) functionalized with organic amine bases, which serves as Pickering interfacial catalysts (PICs) for transesterification reaction. The anisotropic morphology and amphiphilic nature of DS-JPNs promote stable adsorption at the soybean oil-methanol interface, leading to reduced interfacial tension, smaller droplet formation, and the generation of thermodynamically stable emulsions. This microreactor system prominently enhances the interfacial area and mass transfer efficiency, thereby accelerating the transesterification efficiency. Consequently, the DS-JPN-TMA catalyst achieved a biodiesel yield of 85.4 % under static conditions, a 2.6-fold increase compared to the spherical PS-TMA counterpart (34.2 %). Among the examined Janus organic base catalysts, DS-JPN-TBD demonstrated the highest catalytic performance (TOF 12.51 h −1 ), attaining a biodiesel yield of 96.7 %, attributable to the strong basicity of its bicyclic guanidine moieties. Furthermore, DS-JPN-TBD retained 94.2 % of its catalytic activity after five reaction cycles, evidencing excellent reusability and durability. This study underscores DS-JPN-TBD as an innovative, energy-efficient, and sustainable solution for biodiesel production and proposes a scalable strategy for green energy applications.

As the demand for sustainable energy continues to rise, the development of high-efficient hydrogen (H 2 ) production via water electrolysis based on precise bubble manipulation is garnering significant attention. This study presents a novel three-dimensional (3D) micro-cone engineered electrode to enhance the ion exchange rate and catalytic active site regeneration during the electrochemical water splitting process, thereby improving H 2 production rates. The unique micro-cones enables precise manipulation of H 2 bubble behavior, which achieves directional transport from nucleation to detachment at the top within a mere 224 ms. Simultaneously, the bubble manipulation performance of micro-cones with varying geometric configurations and dimensional parameters is investigated. The optimal bubble manipulation performance is achieved when the micro-cones have a circular base with a diameter of 100 μm, a height of 300 μm, and an array center distance of 100 μm. The performance of the 3D micro-cone engineered electrode outperforms conventional commercial electrodes, with its capacitance ( C dl ) value reaching 35.1 mF cm −2 , which is significantly higher than those of Ni foam and Ni-CP. Additionally, under a 1.7 V vs. RHE condition, the electrode achieves a current density of 80 mA cm −2 , with a H 2 collection rate 32.3 % higher than that of a Ni foam under identical conditions. Large-scale outdoor experiments driven by solar energy further confirm the scalability and stability of the micro-cone engineered electrodes, which is capable of producing substantial H 2 quantities over extended periods without bubbles blockage. The large-area micro-cone electrodes, when operated continuously under high outdoor current density, still exhibit excellent H 2 production and bubble directional manipulation stability. This research highlights the transformative impacts of advanced electrode design on water electrolysis efficiency and H 2 bubbles manipulation, offering new insights for ultra-high efficient sustainable H 2 production.

Releasing residual stress and reducing interface defects are crucial approaches for improving the photoelectric conversion efficiency and performance stability of perovskite solar cells (PSCs). This research introduces nickel chloride (NiCl 2 ) into the electron transport layer of tin dioxide (SnO 2 ) and applies it to the buried interface of all-inorganic CsPbBr 3 PSCs to prepare carbon-based FTO/SnO 2 -NiCl 2 /CsPbBr 3 /C cell devices. Through the morphological and structure characterization, it is found that introducing nickel chloride facilitates the formation of large and dense perovskite films with residual strain released and the passivation of interface defects. Simultaneously, an analysis of the interfacial energy level structure reveals that optimized energy levels enhance electron-hole separation and transport efficiency while effectively suppressing non-radiative recombination. The open-circuit voltage of the all-inorganic perovskite solar cell base on the SnO 2 -NiCl 2 electron transport layer reaches to 1.591 V, and optimal photoelectric conversion efficiency (PCE) of the solar cell devices has been improved from 8.11 % of the control to 9.33 % with NiCl 2 , and the unencapsulated device V OC long term stability maintained 96.9 % within 30 days under atmospheric environment conditions. This study provides new insights into the design of efficient electron transport layer materials to enhance the photovoltaic and environmental stability of PSCs.

Development of electrocatalytic reduction of carbonyl compounds for carbon‑carbon (C C) coupling represents an effective pathway to achieve sustainable synthesis of multi‑carbon chemicals. The hydrogen evolution reaction (HER) is considered the most significant competitive process, which could be suppressed by weakening the adsorption of protons on interface or by making protons in the electrolyte inactive through the use of certain additives. However, increasing the coverage of protons and carbonyl molecules are necessary to facilitate the generation of hydrogenation intermediates during C C coupling. To reconcile this contradiction, a Ni-based catalyst for electrocatalytic coupling of formaldehyde has been developed, decorated with phosphate groups around Ni sits. The following enhancement could be achieved: 1) Ni sites enhance the adsorption of formaldehyde on catalyst surface and promote their electroreduction; 2) Phosphate groups near the Ni sites can act as protons affinity sites to prevent their self-coupling. As the result, the adsorbed HCHO and hydrogen can be balanced to facile the formation of intermediate *CH 2 OH during C C coupling. Consequently, the PD-Ni/C@CP catalyst exhibits outstanding performance in the continuous preparation of ethylene glycol, with a production rate of 22 mmol/(L·min) and a Faradaic efficiency exceeding 90%, highlighting its potential for the efficient and sustainable synthesis of other high-value chemicals.

The development of portable, low-power H 2 S sensors is critical for environmental safety but remains challenged to balance high sensitivity with mechanical flexibility at room temperature. Herein, we present a hierarchical SnO 2 /SnS 2 nanoflower composite synthesized via a facile in-situ sulfidation strategy, which ensures intimate lattice coherence for robust flexible sensing. The optimal sensor on a PET substrate exhibits a high response of 19.01 to 10 ppm H 2 S at 25 °C, a low theoretical detection limit of 95.38 ppb, and excellent mechanical stability under 90° bending. Mechanistically, Mott-Schottky analysis confirms that SnO 2 /SnS 2 heterojunctions induce a 50-fold increase in carrier concentration. This electronic modulation extends the Debye length (24.4 nm) beyond the average crystallite size (16.9 nm), creating a volume depletion state in ambient air that enables massive resistance modulation upon H 2 S exposure. This work demonstrates a robust flexible sensor and establishes a quantitative criterion for heterojunction design through Debye length engineering.

The development of simple and efficient synthesis strategies for multicolor fluorescent carbon dots (CDs) is crucial for advancing their applications in fields such as optoelectronic devices and fingerprint detection, and other fields. This study reports a “one-step synthesis combined with Thin Layer Chromatography (TLC) separation” strategy for the successful preparation of multicolor fluorescent CDs covering the entire visible spectrum (499-628 nm) under constant solvothermal conditions, using Neutral Red as the sole core precursor. The separated monochrome components—red (R-CDs), orange (O-CDs), yellow (Y-CDs), and green (G-CDs)—exhibit excellent optical properties, with R-CDs achieving a quantum yield (QY) as high as 20.3%. Systematic structural and spectral characterization reveals that the multicolor luminescence of these CDs does not originate from the conventional quantum confinement effect but is dominated by their surface states. The energy of these surface states is precisely tuned by the graphitization degree of the carbon core and the type of nitrogen-containing functional groups. Leveraging their superior optical properties and solid-state luminescence, the separated multicolor CDs were successfully applied in solid-state lighting to fabricate monochrome light-emitting diodes (LEDs) emitting bright orange, yellow, and green light, respectively. Furthermore, by compounding the highly luminescent R-CDs with starch, high-fidelity imaging of latent fingerprints (LFPs) was achieved, with second-level details being clearly visible. This research provides a new pathway for the low-cost production of multicolor fluorescent carbon dots, showcasing their broad application prospects in the field of advanced functional materials.

Developing robust methods to discriminate methanol from ethanol is critical for industrial safety and quality control. Herein, we report a novel strategy of two-step solvothermal method to synthesize dual-emission carbon dots ( p -PD CDs) from p -phenylenediamine. The p -PD CDs exhibit unique, solvent-dependent fluorescence: in ethanol, they display a dominant blue emission at 445 nm with a weaker red emission at 598 nm; while in methanol, the blue emission is significantly quenched and red-shifted to 465 nm. This distinct solvatochromic response provides a ratiometric luminescent signal ( I 445 /I 598 ) for highly selective methanol detection in ethanol across two linear ranges (1-60 vol% and 60-100 vol%), achieving a detection limit of 0.38 vol%. Comprehensive characterization using transmission electron microscopy (TEM), femtosecond transient absorption (fs-TA), and ultraviolet photoelectron spectroscopy (UPS) revealed that the emission differences originate from methanol-caused aggregation of p -PD CDs. This aggregation is driven by weaker hydrophobic interactions and stronger hydrogen bonding compared to ethanol, leading to aggregation-caused quenching (ACQ) and an accelerated non-radiative decay pathway for the blue emission, as confirmed by time-resolved and transient absorption spectroscopy. The practical utility was successfully demonstrated by accurately quantifying methanol in industrial ethanol and a commercial cleaner with excellent recovery rates (99.5-101.7%), highlighting its significant potential for real-world application.

Comprehension of real-world physical properties is a prerequisite for robotic embodied intelligence, crucially supported by advancing human-like tactile sensing. Though large-scale tactile sensing arrays are indispensable for improving resolution and accuracy, they are hindered by insurmountable scalability barriers—signal crosstalk and the overwhelming redundancy of data acquisition systems. In contrast, biological tactile perception systems can simultaneously and efficiently transmit and process stimuli from multiple receptors with distinct functions. To bridge this gap, we report a neuro-inspired tactile system integrating multiparametric sensing, neuromorphic encoding, and a cognitive framework to construct a complete sensation–perception–decision pathway. Specifically, we engineer a high-resilience aerogel/sponge composite structure featuring high sensitivity (7.54 kPa −1 ) and exceptional cyclic stability, along with self-decoupling thermal sensing (0.1 K resolution; 20.85 μV·K −1 sensitivity). This is paired with an ultrasensitive (21.86 kPa −1 ) toughened conductive thin film offering an ultrafast response (1.3 ms). By integrating these core sensors and spatial frequency encoding circuits into distinct spatial hierarchies to mimic the mechanism of the biological spinal tactile nerves, we realize signal-separable bus transmission and effectively emulate the typical firing dynamics of fast-adapting, slow-adapting, and thermal receptors. Finally, a large language model-driven iterative model is introduced, which synthesizes multimodal data to achieve nuanced comprehension of physical properties (compliance, roughness, and thermal insulation) and establish personalized classification criteria aligned with subjective user perception (94% accuracy). Real-world applications demonstrate that this holistic biomimetic design endows the robots with sensory acuity to extract rich multimodal information, laying a foundation for enhancing their understanding of physical properties.

Electronic control of nanoparticle active sites via a single-atom promoter remains challenging in heterogeneous catalysis. Here we show that spatial positioning of single-atom Zr promoters on hydroxyapatite, either surface-decorated or near-surface lattice-incorporated, possesses different electronic modulation mechanisms. Characterizations and DFT indicate that surface-decorated Zr exhibits limited electron donation to the metal while minimally perturbing the support electronic structure. Lattice-incorporated Zr induces directional charge reconstruction accompanied by support-promoter-metal electronic coupling, thereby enabling significant tuning of the electronic structure of the metal nanoparticles. In 1,2-propanediol dehydrogenation to hydroxyacetone, the lattice-incorporated architecture delivers 83% yield, and 100 h stability under optimized conditions. The same spatial-positioning principle extends beyond Cu and is reproduced in Ni/Zr-HAP and Pt/Zr-HAP. Lattice-incorporated Pt also steers cyclohexanol conversion toward deep ring dehydrogenation, enhancing phenol formation while suppressing dehydration by-products. Overall, axial promoter placement is a transferable lever to engineer interfacial charge distribution for efficient dehydrogenation.
