HS-FeNi-BNC is synthesized via B-bridging, with hollow porous carbon and Fe-B-Ni diatomic sites. • Fe-B-Ni bridge enables p-d hybridization to tune metal sites' electronic structures. • HS-FeNi-BNC delivers exceptional ORR/OER/HER electrocatalysis in alkaline media. • HS-FeNi-BNC-based ZABs operate from −10 to 60 °C with 92.9% Zn utilization efficiency. Rechargeable zinc-air batteries (ZABs) require efficient electrocatalysts to boost the sluggish oxygen reduction reaction (ORR)/ oxygen evolution reaction (OER) kinetics at the air cathode. However, designing high-activity catalysts faces considerable challenges due to spatial and electronic constraints. Herein, a boron-doped hollow spherical porous carbon (HS-FeNi-BNC) anchored with Fe-B-Ni diatomic sites is prepared via a facile B-bridging strategy, realizing the regulated construction of heteroatom doping and diatomic active sites. HS-FeNi-BNC possesses abundant micropores/mesopores, uniformly dispersed Fe Ni diatomic centers (0.27 nm spacing) with a Fe-B-Ni bridge structure, and topological carbon defects induced by B/N co-doping. HS-FeNi-BNC exhibits exceptional trifunctional electrocatalytic performance in alkaline electrolytes, with an ORR E 1/2 of 0.864 V, an OER overpotential of 308 mV and a hydrogen evolution reaction (HER) overpotential of 301 mV at 10 mA cm −2 . HS-FeNi-BNC-based ZABs achieve an outstanding wide-temperature operating range of −10 °C to 60 °C, a specific capacity of 761.51 mAh g −1 and a Zn utilization efficiency of 92.9%, outperforming Pt/C + RuO 2 -based ZABs. Density functional theory (DFT) calculations reveal that the Fe-B-Ni bridge structure triggers p-d orbital hybridization, regulating metal site electronic structures, optimizing reaction intermediate adsorption and accelerating interfacial electron transfer. This work advances the development of high-efficiency heteroatom-modified non-noble metal multifunctional catalysts. Download: Download high-res image (207KB) Download: Download full-size image

Whole-cell biocatalysis of hydrophobic substrates is fundamentally constrained by low solubility and mass transfer limitations, which hinder effective coupling between substrate transport and intracellular metabolism. Herein, we report an interface-regulated nano–bio hybrid system that overcomes these limitations by enhancing substrate accessibility at the microorganism interface. By immobilizing Pseudomonas aeruginosa ( Pas ) onto a coordination-engineered dicopper material (DTD-Cu), a confined nano–bio interface ( Pas @DTD-Cu) is constructed, enabling localized enrichment of hydrophobic substrates and shortening diffusion distances. As a result, the catalysis efficiency of Pas @DTD-Cu is increased to over 200% of that of free bacteria, while maintaining stable activity across a broad pH range (1–11). The increments in ATP, total protein, NADH, and the NAD + /NADH ratio illustrate that the metabolic flux in Pas increases without altering the degradation pathways, suggesting that the performance improvement originates from interfacial regulation rather than pathway modification. This work establishes an interface-controlled strategy for efficient biocatalysis of hydrophobic substrates.

A facile one-pot strategy synthesizes porous B-NiCo-LDH/Ti 3 C 2 2D/2D heterostructures. • B doping tunes electronic structure and strengthens NiCo-LDH/Ti 3 C 2 interfacial bond. • Composite shows enlarged surface area and optimal porous structure for ion transport. • This work offers a universal strategy for designing doped 2D heterostructures. MXenes and layered double hydroxides (LDHs) emerge as advanced electrode candidates for high-performance supercapacitors. Nevertheless, pure Ti 3 C 2 or LDH suffers from either self-stacking or low electronic conductivity and instability. In this work, porous B-doped NiCo-LDH (B-NiCo-LDH) anchored on Ti 3 C 2 nanosheets has been designed and fabricated via a one-pot co-precipitation reaction. Element doping, composite fabrication and structural regulation are realized simultaneously via a simple one-step synthetic strategy. The obtained 2D/2D B-NiCo-LDH/Ti 3 C 2 heterostructures combine the advantages of LDH, Ti 3 C 2 , element doping and porous structure. Boron incorporation diminishes interfacial binding energy in the B-NiCo-LDH/Ti 3 C 2 system, expedites electron movement across interfaces, and ameliorates the composite’s electrical conductivity. The optimal B-NiCo-LDH/Ti 3 C 2 -20 delivers a specific capacitance of 1581.66 F g −1 at 1.0 A g −1 , a rate capability with 82.73% capacitance retention at 20 A g −1 , and a cycling stability of 77.55% after 5000 cycles. An aqueous battery-type hybrid asymmetric supercapacitor (HASC, B-NiCo-LDH/Ti 3 C 2 -20//Bi 2 O 3 /Ti 3 C 2 ) exhibits an energy density of 87.28 Wh kg −1 at a power density of 753.86 W kg −1 . This work provides a feasible strategy for improving energy storage performance via the design of element-doped 2D heterostructures.

In this research, we successfully synthesized a novel Li 5 Mg 21 TiAl 3 O 30 ceramic via the traditional solid-state reaction. This ceramic, when sintered at 1360 °C, demonstrated favorable microwave dielectric properties (MDPs), characterized by an εᵣ of 10.73, a Q×f of 81,598 GHz (at 12.61 GHz), and a τ f of −27.65 ppm/°C. In addition, the Deep Deterministic Policy Gradient (DDPG) algorithm was employed to optimize a ceramic-based dielectric resonator antenna (DRA) intelligently. Through this approach, the antenna parameters were effectively optimized, achieving a design with a center frequency of 7.90 GHz, a low return loss (S 11 ) of –53.6 dB, and a wide bandwidth of 1050 MHz, and a radiation efficiency of 92.55%, aligning the requirements of the 6 G band. The innovative application of deep learning technology improved the DRA design optimization process, offering a new paradigm for the intelligent design of ceramic-based microwave communication devices.

To overcome the poor bioaccessibility of Coenzyme Q10 (CoQ10), we developed a polyethylene glycol-based dripping pill (DP) solid dispersion system. The optimized formulation achieved an amorphous state, resulting in uniform morphology, significantly accelerated dissolution, and enhanced oral bioavailability compared to crystalline CoQ10. In an isoproterenol-induced oxidative cardiac stress model, CoQ10 DPs showed demonstrated cardioprotective bioactivity by alleviating cardiac remodeling and oxidative injury. These protective effects were associated with reduced reactive oxygen species (ROS) accumulation, restored superoxide dismutase (SOD) activity, and decreased inflammatory marker levels. This study presents a robust formulation strategy to maximize the bioactivity of lipophilic nutrients for functional food applications.

Biomarkers for acute myocarditis (AM) are commonly used in clinical diagnosis, but their ultralow concentrations in blood are challenging to be detected in the early stage. This study presents a novel bowl-shaped surface-enhanced Raman scattering (SERS) substrate with high-performance, prepared via one-step hydrofluoric acid etching of SiO 2 microspheres, 515 nm femtosecond-laser reduction of gold ions, and nanosecond-laser reshaping of gold nanoparticles (AuNPs). In particular, 500 nm SiO 2 microspheres were etched with a hydrofluoric acid solution to form a uniform microbowl array, and AuNPs were synthesized in situ on the SiO 2 microbowls via irradiation with a femtosecond laser. Subsequently, the AuNPs were reshaped into nanorods using a nanosecond laser. The resulting bowl-shaped AuNP@SiO 2 substrate showed a SERS enhancement factor of 10 6 and a limit of detection of 3.84 × 10 −8 M, as evaluated on Rhodamine 6G. Notably, the limits of detection of the AM biomarkers were lower than 6 pg/mL, enabling the accurate detection of their trace quantities. For AM prediction, a fuzzy logic model was trained, enabling the accurate and quantitative analysis of biomarkers, with a mean relative error of less than 25.7%. Thus, the proposed SERS platform is a reliable tool for the early noninvasive diagnosis of AM.

To address the persistent challenge of membrane wetting during oil-gas separation in transformer condition monitoring, an omniphobic composite membrane was developed to facilitate the reliable online detection of dissolved gases. An F-CNTs/Teflon AF/PVDF composite membrane, featuring a loofah-like hierarchical structure and omniphobic properties, was fabricated via spraying-deposition strategy on the polyvinylidene fluoride (PVDF) substrate. The morphology, surface chemical composition, wettability and stability of the F-CNTs/Teflon AF/PVDF composite membrane were systematically characterized. Subsequently, the oil-gas separation performance of the composite membrane was evaluated using standard transformer oil containing dissolved gases as the feed solution. The results indicated that fluorinated carbon nanotubes (F-CNTs) were successfully modified onto the membrane surface, creating a re-entrant morphology composed of an intersecting nanotube network that mimics the hierarchical architecture of a loofah. The F-CNTs/Teflon AF/PVDF composite membrane exhibited exceptional omniphobicity, achieving contact angles of 168.2 ± 1.5° and 127.5 ± 1.0° towards DI water and mineral insulating oil, respectively. Additionally, the loofah-inspired composite membrane demonstrated robust thermal and ultrasonic stability. In oil-gas separation tests, the omniphobic membrane displayed a rapid response and high efficiency for dissolved gas extraction, achieving dynamic equilibrium within 64 min. Furthermore, the modification improved permeation efficiency by 25.6%. These results suggest that the developed omniphobic membrane is a promising alternative for oil-gas separation in the condition monitoring of oil-filled electrical equipment.

Microcystin contamination caused by harmful cyanobacterial blooms is a growing global challenge for water safety. Here we reported a self-assembled living microreactor that encapsulated microcystin-degrading bacteria within a biochar-reinforced double-network hydrogel, enabling integrated molecular sieving, adsorption, and enzymatic degradation. The system exhibited size- and charge-selective removal of microcystin over coexisting organic matters, while maintaining high degradation efficiency under harsh stress conditions, including pH (5−9), inorganic ions (10−200 mg/L), and natural organic matters (5−20 mg/L). The microreactor demonstrated excellent mechanical stability, negligible cell leakage, and high bioactivity, and achieved nearly complete removal of microcystin-LR during five repeated operation cycles and continuous biofiltration in environmental water, confirming its scalable application potential. Mechanistic investigations revealed a cascade process involving shell-confined molecular sieving, adsorption-mediated toxin enrichment on biochar, and localized biodegradation within the living core. This work establishes a generalizable design paradigm for programmable living materials, offering new opportunities for selective biodegradation and remediation in complex aqueous systems.

Hydrogen evolution reaction (HER) and uncontrolled dendrite growth remain persistent challenges for aqueous Zn-ion batteries (AZIBs). In this study, the Y element is utilized to adjust the bandgap width of the anode coating, thereby serving as electron transfer gating and consequently suppressing HER from a dynamic perspective. The Gibbs free energy ( ΔG H* ) data for H * adsorption reveal that the presence of the Y can hinder the desorption of H 2 from the surface of the semiconductor coating. It effectively restrains HER from a thermodynamic viewpoint. Furthermore, the improved zincophilicity of the amorphous wide-bandgap semiconductor coating offers a multitude of uniform nucleation sites for Zn 2+ deposition. A balance between H * adsorption and Zn 2+ affinity is achieved by this wide bandgap semiconductor, enabling strong HER inhibition and highly efficient Zn-induced deposition. The symmetric cell achieves stable cycling for over 6700 h at 2 mA cm −2 and 1 mAh cm −2 . Even under a high current density of 10 mA cm −2 and 5 mAh cm −2 , a cycle life of 1200 h is maintained. The Zn–V full cell exhibits a cycling lifespan of 3800 cycles at 5 A g −1 .

Steel components in thermal power plants are vulnerable to severe wear and wall thinning induced by the high-velocity impact of pulverized coal, which significantly compromises their service life and structural integrity. To address this issue, a TiC-reinforced AlCoCrFeNi high-entropy alloy (HEA) composite coating was fabricated via laser cladding, aiming to substantially enhance the wear resistance of these critical components. The phase composition, microstructure, microhardness and tribological behaviors of the coatings were systematically investigated by XRD, SEM, EDS and dry sliding wear tests. Results show that both coatings possess dense microstructures and reliable metallurgical bonding with the substrate. The AlCoCrFeNi coating consists of a single BCC solid solution phase, while the TiC/AlCoCrFeNi composite coating contains a BCC phase and a TiC ceramic phase without brittle intermetallic compounds. The average microhardness of the TiC/AlCoCrFeNi composite coating was measured to be 823 HV0.3, which is 85.66% greater than that of the AlCoCrFeNi coating (443 HV0.3). Under identical wear test conditions, the AlCoCrFeNi coating exhibits a mass loss of 31.4 mg and a volumetric wear rate of 24 × 10−3mm3/min, whereas the TiC/AlCoCrFeNi composite coating exhibits a mass loss of 15.6 mg and a wear rate of 13 × 10−3mm3/min, corresponding to reductions of approximately 50.32% and 45.83%, respectively. The wear mechanism of the AlCoCrFeNi coating is dominated by severe abrasive wear coupled with adhesive wear, while the addition of TiC converts the wear mechanism into mild abrasive wear and oxidative wear. The incorporation of TiC particles effectively enhances the microhardness and reduces the mass loss, thereby contributing to a marked improvement in the wear properties of the laser-clad AlCoCrFeNi coating. This research provides experimental data and theoretical support for the engineering application of TiC/AlCoCrFeNi composite coatings on wear-resistant components in thermal power units.

Polymer-stabilized liquid crystal (PSLC) films are promising for smart window applications because of their transparent-to-scattering switching behavior. However, conventional acrylate-based PSLC films often suffer from poor mechanical robustness and weak interfacial adhesion, limiting their use in flexible devices. Herein, epoxy-based PSLC films have been prepared through radical-promoted cationic photopolymerization using a difunctional epoxy monomer, E6M, and a series of liquid-crystalline monoepoxy monomers, E-nOCB. The effects of alkyl chain parity, chain length, and E6M/E-10OCB ratio on polymer morphology, electro-optical behavior, and peel strength were systematically investigated. Even-numbered E-nOCB monomers favored the formation of regular columnar polymer structures and improved optical contrast, whereas odd-numbered monomers produced more disordered networks with higher peel strength. Among them, the sample prepared with E-10OCB showed a better balance between electro-optical performance and mechanical adhesion. At a fixed total polymer content of 15 wt%, optimizing the E6M/E-10OCB ratio enabled the sample doped with E-10OCB to achieve the highest contrast ratio of 160.91 while increasing the peel strength from 47.28 to 55.69 kPa compared with the sample without E-10nOCB. These results demonstrate that regulating monoepoxy/diepoxy composition and alkyl chain structure is an effective strategy for improving the overall performance of epoxy-based PSLC films for smart windows.

Efficient and environmentally benign recovery of precious metals from complex aqueous systems remains a central challenge. Here, we demonstrate that thermally generated water microdroplets at oil–water interfaces function as highly reactive interfacial microenvironments that enable selective gold reduction and macroscopic particle growth without external reductants, catalysts, or sorbents. Mild heating of oil–water mixtures containing Au ions produces abundant interfacial water microdroplets (5–50 μm) that continuously generate redox-active species, including solvated electrons, hydrogen atoms, and hydroxyl radicals, thereby driving reduction reactions that do not occur in bulk water. Selectivity is governed by a dual criterion: (i) thermodynamic accessibility above the solvent reduction limit imposed by hydrogen evolution and (ii) chemical stability of the reduced phase under strongly acidic conditions. Au satisfies both requirements, and extension experiments with Pt and Ag validate the broader applicability of this principle, whereas competing base metals are excluded either by redox constraints or by instability of their reduced forms. Dynamic microdroplet coalescence and rupture further couple redox chemistry with particle growth, promoting nanoparticle aggregation into micrometer- to millimeter-scale Au particles that are readily separated. The oil phase is recyclable over multiple cycles, enabling high-yield gold recovery with minimal inputs and waste generation. These findings, validated across capillary, glass-vial, and upgraded reactor systems, establish interfacial microdroplet chemistry as a scalable framework for selective precious-metal recovery.
