Micro-tubular protonic ceramic fuel cells (MT-PCFCs) exhibit substantial advantages such as high energy conversion efficiency, large volumetric power density, and intermediate operating temperature. The performance of MT-PCFCs is highly dependent on the microstructure of the microtubes. In this study, BaCe 0.7 Zr 0.1 Y 0.2 O 3-δ (BCZY)/Ni-BCZY (electrolyte/anode) dual-layer hollow fibers (DLHFs) are fabricated in a single step by co-spinning/co-sintering technique, which significantly reduces manufacturing time and cost. The relationship between the MT-PCFCs performance and the microstructure of the DLHFs is investigated. By adjusting the cermet powder content and the spinning rate, the microstructure of DLHFs is tailored and optimized to achieve the best performance for the MT-PCFCs. Experimental results indicate that the anode structure with thick finger-like voids inside and thin sponge-like interlayer closely attached to the thin electrolyte film is favorable to obtain high performance MT-PCFCs. A maximum power density of 554.5 mW cm -2 for the optimal MT-PCFC is achieved at 700 ℃.

Biodegradable poly(L-lactic acid) (PLLA) has seldom used for dairy packaging due to medium permeability and brittleness. Novel PLLA copolymers, poly (L-lactic acid- co -butylene itaconate-co-glycolic acid) (PLBIGA), were developed by integrating glycolic acid (GA) and poly(butylene itaconate) (PBI) into PLLA's structure using low molecular weight PLLA as a key initiator. Then, packaging materials with better barrier and mechanical properties were obtained by blended PLBIGA with PLLA. Both PLLA/PLBIGA films and polyethylene nylon composite film (PE/NY) were used for stirred yogurt packaging and storage at 4 °C for 25 days. Results revealed that yogurt packed by PLLA/PLBIGA films maintained stabler water-holding capacity, color, and viscosity over the storage period. Moreover, the integrity of the gel structure and the total viable count of lactic acid bacteria in yogurt packaged in PLLA/40-PLBIGA8 were also found to be superior to those in PE/NY packages, highlighting its eco-friendly advantages in dairy packaging.

The catalytic activity, adsorption and synergistic effect over bimetallic MOF derivatives with different dopant metal were systemically compared. A series of Me-Cu/TiO 2 (Me=Fe, Co, Ni) derived from bimetallic Me/Cu-BTC MOFs were fabricated via a sacrificing template method and applied for CO-SCR. Among the bimetallic catalysts, Fe-Cu/TiO 2 presented the best low-temperature of nearly 100% NO conversion from 150 °C to 350 °C with good NO selectivity. For Me-Cu/TiO 2 (Me=Fe, Co, Ni), the productions of crucial Cu + intermediate were determined to be 51.17%, 50.45%,49.4% by XPS, which were consistent with their catalytic activity results. The superior redox behavior of Fe-Cu/TiO 2 can be attributed to its higher Oβ / (Oα +Oβ) ratio of 32.90% and the higher Me 2+ / Me 3+ ratio of 1.79. In situ infrared analysis revealed that the Fe doping not only improved the formation and stability of nitrate species, but also enhanced the quantity of Lewis acid sites by forming Cu + -CO. Furthermore, a possible low-temperature Langmuir-Hinshelwood (L-H) mechanism over Me-Cu /TiO 2 (Me=Fe, Co, Ni) was proposed.

The accumulation of heavy metals (HMs) and microplastics in soil has emerged as a major environmental challenge worldwide. In this study, a series of biochars were developed using hollyhock straw as the raw material to remediate soils co-contaminated with Pb, Cr, and Cd. Additional experiments were conducted to assess the impact of polyethylene microplastics (PE-MPs) on the efficacy of biochar in soil remediation. In this study, we utilized the inexpensive and readily available warm patches, which are composed of iron, vermiculite, and activated carbon, in combination with a green and economical deep eutectic solvent (MAG) as modifying agents for biochar. The warm patch and deep eutectic solvent-co-modified biochar (MAG-WIM/B) exhibited superior performance in immobilizing HMs, improving the soil physicochemical properties, enhancing the functional enzyme activity, and increasing the microbial community diversity of soil. Soil incubation experiments showed that the addition of MAG-WIM/B reduced DTPA-extractable Pb, Cr, and Cd contents by 50.8 %, 46.7 %, and 24.2 %, respectively, by day 82. Monte Carlo simulations further revealed a preferential adsorption of Pb in the ternary HM system. Moreover, the introduction of MAG-WIM/B led to a significant improvement in the urease activity and shifted the dominant microbial species from Proteobacteria to Actinobacteria . PE-MPs significantly limited the effectiveness of biochar in remediating HM-contaminated soil by altering its physicochemical properties and competing with HMs for the active sites present on biochar. This work provides a strategic framework for the remediation of soils co-contaminated with multiple HMs and PE-MPs.

A simple and efficient route was used to prepare an amphiphilic copolymer (poly(propylene glycol)-co-poly(ethylene glycol)-co-poly(propylene glycol)) (PPG-co-PEG-co-PPG) by one-pot polymerization reaction. This copolymer was used as the hydrophilic additive in preparation of poly(vinylidene fluoride) (PVDF) ultrafiltration membranes via immersion–precipitation process. Surface characteristics of the membranes were confirmed by contact angle measurements, zeta potential, attenuated total reflectance Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy and atomic force microscopy. During filtration experiments, the modified membranes showed better permeation and antifouling performances compared to PVDF membranes with bovine serum albumin, sodium alginate and yeast. After hydraulic stirring cleaning with deionized water, water flux recovery and rejection ratio of the modified membranes were higher than those of pristine PVDF membrane, and the flux recovery ratio was maximized at 94.29%. It was suggested that PPG-co-PEG-co-PPG copolymer was anchored in the PVDF membrane through the two hydrophobic ends of PPG blocks, while the hydrophilic intermediate of the PEG block segregated onto the membrane or pore surface during the membrane preparation process. The synthesized method of amphiphilic PPG-co-PEG-co-PPG copolymer paved a novel way to solve the problems of less compatibility between the copolymer and membrane matrix and instability with water molecules in the ultrafiltration process.

To mitigate interconnect corrosion in seawater-fed solid oxide electrolysis cells (SOECs), Mn 1.5 Co 1.5 O 4 spinel coatings were deposited on Fe-22Cr stainless steel. At 750 °C, the coated interconnects exhibited an area-specific resistance (ASR) of 31.8 mΩ cm 2 after 4835 h of oxidation in air, with a parabolic rate constant of 3.0 × 10 −5 mg 2 cm −4 h −1 . Following exposure to seawater vapor for 500 h, the ASR reached 3.36 mΩ cm 2 , with a predicted value of 9.80 mΩ cm 2 at 5000 h. These findings underscore the coating’s improved oxidation resistance under dual-atmosphere conditions. Furthermore, a three-cells stack demonstrated high stability with a low degradation rate of 1.04 × 10 −5 h −1 at 100 mA cm −2 for 100 h. Post-test analysis confirmed a crack-free structure with negligible additional resistance, indicating that the spinel coating satisfies the engineering requirements for durable, direct seawater electrolysis and provides a scalable pathway for green hydrogen production.

Artificial photosynthesis of acetaldehyde from atmospheric CO 2 is highly promising, yet remains severely limited by low CO 2 concentration in air and sluggish proton transfer kinetics. Herein, we report metallo hydrogen-bonded organic frameworks (MHOFs) of HNNU-X (X = O, S, Se) which enable acetaldehyde synthesis directly from air, water, and natural sunlight. Among them, HNNU-Se exhibits a competitive acetaldehyde production rate of 557.1 μmol g⁻¹ h⁻¹ with high electron-based selectivity of 95% under outdoor conditions, without need of sacrificial agents. Mechanistic studies reveal that HNNU-X creates a proton-rich microenvironment in which [Zn(tpy)] 2+ cations function as CO 2 capture and activation sites for direct air capture, while [XCN] – anions serve as proton shuttles, facilitating rapid transfer of in-situ generated H⁺ from solar-driven water oxidation to adsorbed CO 2 . This work enables the synergistic coupling of CO 2 reduction and H 2 O oxidation, thereby achieving efficient artificial photosynthesis of acetaldehyde. This study develops metallo hydrogen-bonded organic frameworks (HNNU-X), which overcome the low CO 2 concentration in air and sluggish proton transfer kinetics, achieving artificial photosynthesis of acetaldehyde from air, water and natural sunlight.

Lead-free antiferroelectric AgNbO 3 (AN) ceramics hold significant potential for pulsed power systems; however, their inferior energy storage density and efficiency limit their practical deployment. Optimizing performance under moderate electric fields (300–500 kV cm −1 ) is particularly critical for industrial viability. Herein, a Bi 3+ /Yb 3+ A-site co-doping strategy is proposed to optimize the microstructural characteristics and improve the electrical properties of AN ceramics. The synergistic doping effect effectively enhances antiferroelectric stability and dielectric relaxation behavior, while concurrently suppressing the rapid decay of saturation polarization intensity. Furthermore, refined grain size and a widened band gap jointly improve the breakdown electric field strength. Benefiting from such multi-scale modulation, Ag 0.82 Bi 0.03 Yb 0.03 NbO 3 (ABYN3) ceramic demonstrates a high recoverable energy density of 6.8 J cm −3 and an energy efficiency of 77% under an applied field of 431 kV cm −1 . Moreover, ABYN3 demonstrates superior thermal stability, high frequency tolerance, and resistance to cyclic fatigue. Charge–discharge measurements reveal that ABYN3 exhibits a discharge energy density of 4.06 J cm −3 and an ultrahigh power density of 144 MW cm −3 at 300 kV cm −1 , along with an ultrafast discharge speed (t < 100 ns). This study presents a feasible and effective strategy for performance optimization of lead-free antiferroelectric ceramics, providing valuable guidance for their practical industrial applications in pulsed power systems.

The regulation mechanism of interfacial coatings on CO electroreduction has not yet been unraveled even though high CO-to-C 2+ conversion is observed. In this work, in situ spectroscopy techniques were employed to decouple the regulatory rules of carbon coatings on the hydrogen-bonding network and adsorbed carbon monoxide at the copper-based catalytic interface for CO electroreduction. The coated-carbon layers could promote the CO-to-C 2+ conversion efficiency, as the C 2+ selectivity increased from below 66% (for pure Cu) to above 77% in alkaline electrolyte. Combined with in situ electrochemical infrared spectroscopy, online mass spectrometry, and theoretical calculations, it was found that the carbon coating could reconstruct the interfacial hydrogen-bonding network and enhances its orderliness, thereby inducing more favorable hydrogenation steps for intermediates compared to hydrogen evolution. Meanwhile, the Cu–C interface tunes the vibrational state of linearly adsorbed CO, strengthens Cu–CO interactions, and lowers the energy barrier for C–C coupling toward C 2+ products. To further demonstrate the practical relevance of this mechanism, a self-designed compact integrated CORR prototype was developed, which maintained an ethylene Faradaic efficiency above 40% over 24 h at 15 A. These findings provide molecular-level insight and practical guidance for the design of interfacial-modified Cu catalysts for efficient CO electro-conversion.

Elucidating the role of hydrogen spillover in regulating the active sites of metal-acid catalysts is essential to enable selective lignin hydrodeoxygenation toward aviation biofuels. Herein, we developed a MoO 3 /Co@CoO catalyst that enables efficient hydrodeoxygenation of lignin and its derivatives into aviation biofuels. The catalyst achieved nearly complete conversion of monomeric phenolic derivatives with ∼99% selectivity toward aviation-range hydrocarbons, while lignin afforded 16.3 wt % liquid hydrocarbons with 53.2% selectivity to aviation-range hydrocarbons under mild conditions. Structural analyses confirmed the formation of a Co@CoO core−shell architecture and Co−O−Mo interfacial bonding. Combined experimental and DFT studies revealed that Co 0 sites facilitate H 2 dissociation, whereas the Co−O−Mo interface enables accelerated hydrogen spillover from Co to Mo species, generating Brønsted acid sites (Mo−OH) and driving the selective formation of aviation biofuel components. This work offers fundamental insights into rationally controlling hydrogen spillover via interface engineering in metal-acid catalysts for lignin hydrodeoxygenation.

A Fiber-optic surface plasmon resonance (SPR) bilirubin biosensor based on gold nanoparticles (AuNPs) and bilirubin oxidase (BOD) was proposed in this work. Leveraging the refractive index (RI) sensitivity of SPR and the specific binding capability of BOD to bilirubin, this sensor enables specific detection of bilirubin. To improve the sensitivity of bilirubin detection, AuNPs were introduced to amplify the evanescent field for optical signal enhancement while providing a high surface area for increased BOD immobilization sites. Experimental results demonstrated that the sensor achieved a sensitivity of 54.6 nm/mM within the 0–0.14 mM concentration range and a detection limit of $11.5~\mu $ M. This sensor exhibits the advantages of low sample consumption, compact size, rapid response, good stability, and high specificity. Additionally, the accurate detection of bilirubin in real serum samples demonstrates its great application potential for clinical diagnosis.

Zero-dimensional rare-earth halide Cs 3 EuCl 6 : Tb 3+ , Sb 3+ nanocrystals (NCs) were successfully synthesized via a facile heating method. Their optical temperature sensing properties are systematically investigated. By virtue of the efficient energy transfer of Tb 3+ →Eu 3+ and the reduction in site symmetry of luminescent centers at high temperature, the emission peaks of Tb 3+ and Eu 3+ show different temperature response. Based on this, an optical thermometry system based on the fluorescence intensity ratio (FIR) is constructed. The maximum relative sensitivity of Cs 3 EuCl 6 : 40%Tb 3+ NCs reaches 1.301%·K −1 . Further introduction of Sb 3+ co-doping not only remarkably enhances the luminescence intensity of the material, but also raises the maximum relative sensitivity to 1.32%·K −1 . This work confirms that Cs 3 EuCl 6 : Tb 3+ , Sb 3+ NCs are high-performance optical temperature sensing materials with promising application prospects.
