AbstractSr2Fe1.5Mo0.5O6‐δ (SFM) perovskite oxide is one of the most promising materials for solid oxide fuel cells (SOFCs) anode. However, the low catalytic activity is a major roadblock that obstructs its practical applications. Although in situ exsolution of B‐site metals is demonstrated as a promising approach to enhancing its performance, it can easily induce the co‐segregation of A‐site Sr, which seriously deteriorates the performance stability. In this work, the A‐site Sr element in SFM is partially replaced by Pr, while B‐site Mo is partially replaced by Ni. The in situ co‐exsolution of both FeNi alloy and PrOx nanoparticles on the reduced Pr0.8Sr1.2Fe1.5Mo0.3Ni0.2O6‐δ (R‐PSFMN) perovskite is successfully achieved. It is found that the peak power densities (Pmax) of the single cell using R‐PSFMN as the anode reaches as high as 2.29, 1.60, 1.07, and 0.67 W cm−2 in H2 atmosphere at the operating temperatures of 850, 800, 750 and 700 °C, respectively. Furthermore, it also exhibits excellent performance stability and anticoke properties when using ethane as fuel. The impregnation experiment further corroborates that the improved performance and stability are partly attributable to the contribution of PrOx nanoparticles, presenting a promising approach to enhance the electrochemical performance of SOFC perovskite anodes.

AbstractThe lanthanide complex, characterized by narrow emission bands, large Stokes shifts, long luminescence lifetime, robust resistance to photobleaching, and magnetic properties, affords significant promise for molecular imaging and biosensing applications. While most lanthanide complexes emitting visible light are extensively studied for cellular‐level detection and bioimaging, near‐infrared‐emitted (700–1700 nm) lanthanide compounds exhibit more favorable properties for bioimaging and biosensing, ascribed from deeper penetration and reduced bleaching effects. Besides, the magnetic lanthanide complex with higher magnetic resonance signals can enhance image resolution and sensitivity, offering more precise bioimaging analysis. However, the widespread use of high‐efficiency luminescence lanthanide complexes is currently impeded by the lack of design approaches for improving magnetic properties and sensitization chromophores with extended excitation and emission wavelengths. In this review, some fundamental theories and design strategies of lanthanide complexes are summarized for luminescence imaging, lifetime‐engineered imaging, magnetic resonance imaging, and dual‐modal imaging, and now highlight a selection of bioimaging and biosensing applications. The review addresses the existing gap in the literature by proposing some feasible approaches for improving the fluorescent and magnetic properties. Concurrently, future challenges and opportunities in the field of lanthanide complex probes are discussed.

AbstractIn the current battle against antibiotic resistance, the resilience of Gram‐negative bacteria against traditional antibiotics is due not only to their protective outer membranes but also to mechanisms like efflux pumps and enzymatic degradation of drugs, underscores the urgent need for innovative antimicrobial tactics. Herein, this study presents an innovative method involving the synthesis of three furoxan derivatives engineered to self‐assemble into nitric oxide (NO) donor nanoparticles (FuNPs). These FuNPs, notably supplied together with polymyxin B (PMB), achieve markedly enhanced bactericidal efficacy against a wide spectrum of bacterial phenotypes at considerably lower NO concentrations (0.1–2.8 µg mL−1), which is at least ten times lower than the reported data for NO donors (≥200 µg mL−1). The bactericidal mechanism is elucidated using confocal, scanning, and transmission electron microscopy techniques. Neutron reflectometry confirms that FuNPs initiate membrane disruption by specifically engaging with the polysaccharides on bacterial surfaces, causing structural perturbations. Subsequently, PMB binds to lipid A on the outer membrane, enhancing permeability and resulting in a synergistic bactericidal action with FuNPs. This pioneering strategy underscores the utility of self‐assembly in NO delivery as a groundbreaking paradigm to circumvent traditional antibiotic resistance barriers, marking a significant leap forward in the development of next‐generation antimicrobial agents.

AbstractThe discovery of ferroelectricity in nanoscale hafnia‐based oxide films has spurred interest in understanding their emergent properties. Investigation focuses on the size‐dependent polarization behavior, which is sensitive to content and movement of oxygen vacancies. Though polarization switching and electrochemical reactions is shown to co‐occur, their relationship remains unclear. This study employs X‐ray photoelectron spectroscopy with depth sensitivity to examine changes in electrochemical states occurring during polarization switching. Contrasting Hf0.5Zr0.5O2 (HZO) with Hf0.88La0.04Ta0.08O2 (HLTO), a composition with an equivalent structure and comparable average ionic radius, electrochemical states are directly observed for specific polarization directions. Lower‐polarization films exhibit more significant electrochemical changes upon switching, suggesting an indirect relationship between polarization and electrochemical state. This research illuminates the complex interplay between polarization and electrochemical dynamics, providing evidence for intrinsic polar states in HfO2‐based ferroelectrics.

AbstractBlue phosphorescent organic light‐emitting diodes (PHOLEDs) are on the brink of commercialization for decades. However, the external quantum efficiency (EQE) and operational lifetime of PHOLEDs are not yet reached industrial standards. Here, a novel tetradentate Pt(II) emitter with a spirofluorene onto the carbazole unit that minimizes the vibration modes, corresponding to the structural relaxation during the de‐excitation, called the vibration suppression effect is reported. This modification reduces the intensity of the second peak in the spectrum and Shockley–Read–Hall recombination by blocking direct hole injection into the emitter while enhancing Förster resonance energy transfer, resulting in 451 h of LT50 (the time until a 50% decrease in initial luminance at 1000 cd m−2) and 25.1% of the maximum EQE (EQEmax). Thanks to the vibration suppression effect, an extremely narrow full width at half a maximum of 22 nm is obtained. In phosphor‐sensitized thermally activated delayed fluorescent OLED, ultra‐pure blue emission with Commission internationale de l′Eclairage (CIE) coordinates of (0.136, 0.096) is obtained with 28.1% of EQEmax. Furthermore, 50.3% of the EQEmax and 589 h of LT70 are simultaneously recorded with the two‐stack tandem PHOLED, which is the highest EQEmax among 2‐tandem and bottom‐emission PHOLEDs with CIEy < 0.15.

AbstractThis study systematically explores the wetting characteristics of re‐entrant microstructures, focusing on the interplay between the unique geometries and material compositions. While silicon dioxide (SiO₂) re‐entrant microstructures are previously studied, this research pioneers the fabrication of silicon carbide (SiC) re‐entrant microstructures. Through experimental approaches and theoretical analysis, the research assesses how variations in geometry and material impact wettability. Key findings reveal that SiC re‐entrant structures achieve an average contact angle of 145°, closely matching the 148° observed for SiO₂, indicating similar hydrophobic behavior. Although flat SiC surfaces exhibit higher inherent hydrophobicity than flat SiO₂ (59° vs 26° contact angle), re‐entrant geometry predominantly influences wetting behavior, overshadowing material differences. Structures with lower solid area fractions show increased hydrophobicity, with a distinct hierarchy: microlines are the least hydrophobic, followed by shark‐skin textures, rectangles, circles, and triangles. Additionally, increasing the gap size between structures enhanced hydrophobicity up to a critical point. This study paves the way for optimizing re‐entrant microstructures for specific applications, significantly enhancing the understanding of surface science and advancing material design.

AbstractWith a high theoretical gravimetric capacity of 3579 mAhg−1, silicon (Si) has made a promising claim as an alternative to graphite (372 mAhg−1) in lithium‐ion battery (LIB) anodes as an active material. Unfortunately, inherent failure mechanisms (pulverization, delamination, promoting thick interphase formation, and non‐conducting nature) of Si anodes have plagued their way toward commercialization. To stabilize Si anodes, this work reports the design, synthesis, and application of a conducting/crosslinked poly(BIAN) (P‐BIAN) as a polymer binder for Si anodes. Theoretical evaluation of crosslinked P‐BIAN and electrochemical characterization of anodic half‐cells show that the crosslinked P‐BIAN exhibits its versatility by a) administering mechanical robustness to stabilize Si particles, b) undergoing n‐doping owing to the low‐lying lowest unoccupied molecular orbital (LUMO) to tailor a thin solid‐electrolyte interphase (SEI), and c) maintaining electrical conductivity. This inspired Si anodes to show a high reversible capacity of ≈2500 mAhg−1 for over 1000 cycles with 99.1% capacity retention at 500 mAg−1 current‐rate.

AbstractSolid composite electrolytes (SCEs) have attracted serious attention for solid‐state Li metal batteries. In particular, SCEs that incorporate inorganic sulfide into polymer electrolytes provide a feasible approach to address the air sensitivity and (electro)chemical instability of sulfides. Nevertheless, there is still little research on pairing sulfide‐SCEs with high‐voltage cathodes. In this work, reports on efforts to synthesize and compare SCEs that embedding sulfides (Li7PS6 and Li3PS4) into PVDF/HFP polymer using a strong polar solvent (DMF). Two sulfides show distinct behaviors when dispersed in the DMF solvent. The Li7PS6‐SCE exhibits an ionic conductivity of 2.5 × 10−4 S cm−1 at room temperature, higher than the Li3PS4‐SCE (1.75 × 10−4 S cm−1). Moreover, Li7PS6‐SCE displays better electrochemical cycling performance in solid‐state Li metal batteries with LiNi1/3Mn1/3Co1/3O2 (NMC 111) cathode.. When increasing upper cut‐off voltages from 4.0 to 4.4 V, Li| Li7PS6‐SCE |NMC111 cells deliver higher discharge capacities but exhibit worse cycling stability. Interface analysis using X‐ray photoelectron spectroscopy (XPS) reveals the formation of LiF under a high voltage of 4.4 V, while t not present with 4.0 V. This work explores the synthesis of SCEs with different sulfides in a strong polar solvent and highlights the interface reactions between sulfide/PVDF‐HFP SCEs with oxide cathodes.

AbstractThis paper examines the chemical characteristics of four plant‐derived bio‐oils, including waste cooking oils, to address a research gap concerning their effects on the thermal stability and moisture susceptibility of asphalt. While bio‐oils are known to soften asphalt, their specific impact on these properties is less understood. The study evaluates four different bio‐oils (B1–B4) derived from various waste vegetable sources to determine their influence on asphalt performance. The findings indicate that bio‐oils with higher purity and lower polyunsaturated fatty acid content offer better resistance to heat and UV‐induced degradation. Bio‐oils with lower iodine values also show improved resistance to moisture damage. Notably, bitumen composites containing bio‐oil B2 do not negatively affect asphalt's moisture resistance, while others increase its moisture susceptibility. Tests with liquid anti‐strip agents reveal that silanes and amine‐based agents are the most effective at reducing moisture damage. These results underscore the importance of selecting bio‐oils with low acid and iodine values, low polyunsaturated fatty acid content, and high purity for use in asphalt. This study supports sustainability and resource conservation by recommending bio‐oils that preserve the durability of bio‐modified asphalts.

AbstractThe electrochemical reduction of nitrite (NO2−) contaminants to ammonia (NH3) is a sustainable and energy‐saving strategy for NH3 synthesis. However, this multi‐electron reduction process requires an efficient electrocatalyst to overcome the kinetic barrier. Herein, the Pt2Cu1 nanooctahedrons are synthesized through a liquid‐phase chemical reduction process. The synergistic effect of bimetallic Pt and Cu sites in the Pt2Cu1 nanooctahedrons is indispensable for accelerated NO2− hydrogenation, originating from the strong hydrogen‐atoms adsorption capacity at Pt site and the strong NO2− adsorption capacity at Cu site. Specifically, the introduction of Pt sites can accelerate the accumulation of hydrogenated species on the catalyst surface, which promotes the formation of NH3. In 0.5 m Na2SO4 solution, the Pt2Cu1 nanooctahedrons can reduce NO2− to NH3 at a yield of 4.22 mg h−1mgcat−1 and a Faraday efficiency of 95.5% at a potential of −0.14 V versus RHE. Meanwhile, the Pt2Cu1 nanooctahedrons also exhibit excellent activity for the sulfion oxidation reaction (SEOR). Using Pt2Cu1 nanooctahedrons as bifunctional electrocatalyst, a coupled electrolysis system combining the nitrite electrochemical reduction reaction (NO2−ERR) with the SEOR requires only 0.3 V total voltage, enabling energy‐saving electrochemical NH3 production and collective value‐added recovery of nitrite and sulfion waste.

AbstractLysosomes are important cellular structures for human health as centers for recycling, signaling, metabolism and stress adaptation. However, the potential role of lysosomes in stress‐related emotions has long been overlooked. Here, it is found that lysosomal morphology in astrocytes is altered in the medial prefrontal cortex (mPFC) of susceptible mice after chronic social defeat stress. A screen of lysosome‐related genes revealed that the expression of the mucolipin 1 gene (Mcoln1; protein: mucolipin TRP channel 1) is decreased in susceptible mice and depressed patients. Astrocyte‐specific knockout of mucolipin TRP channel 1 (TRPML1) induced depressive‐like behaviors by inhibiting lysosomal exocytosis‐mediated adenosine 5′‐triphosphate (ATP) release. Furthermore, this stress response of astrocytic lysosomes is mediated by the transcription factor EB (TFEB), and overexpression of TRPML1 rescued depressive‐like behaviors induced by astrocyte‐specific knockout of TFEB. Collectively, these findings reveal a lysosomal stress‐sensing signaling pathway contributing to the development of depression and identify the lysosome as a potential target organelle for antidepressants.

AbstractThe efficient co‐production of H2 and CH4 via anaerobic digestion (AD) requires separate stages, as it cannot yet be achieved in one step. Lactic acid bacteria (LAB) (Limosilactobacillus) release H2 and acetate by enhancing hydrolysis, potentially increasing CH4 production with simultaneous H2 accumulation. This study investigated the enhanced effect of one‐step co‐production of H2 and CH4 in AD by LAB and elucidated its enhancement mechanisms. The results showed that 236.3 times increase in H2 production and 7.1 times increase in CH4 production are achieved, resulting in profits of 469.39 USD. Model substrates lignocellulosic straw, sodium acetate, and H2 confirmes LAB work on the hydrolysis stage and subsequent sustainable volatile fatty acid production during the first 6 days of AD. In this stage, the enrichment of Limosilactobacillus carrying bglB and xynB, the glycolysis pathway, and the high activity of protease, acetate kinase, and [FeFe] hydrogenase, jointly achieved rapid acetate and H2 accumulation, driving hydrogenotrophic methanogenesis dominated. From day 7 to 24, with enriched Methanosarcina, and increased methenyltetrahydromethanopterin hydrogenase activity, continuously produced acetate led to the mainly acetoclastic methanogenesis shift from hydrogenotrophic methanogenesis. The power generation capacity of LAB‐enhanced AD is 333.33 times that of China's 24,000 m3 biogas plant.

AbstractBiofertilizers can be better alternatives to chemical fertilizers to enhance plant nutrition and productivity as they improve the soil fertility and crop productivity in an eco‐friendly and cost‐effective manner. A pot experiment was conducted between December 2018 and March 2019 in southern Ethiopia to evaluate the combined inoculation of arbuscular mycorrhizal fungi (AMF) and Meso‐rhizobium (MR) on biomass yield, nutrient uptake, and moisture stress tolerance of chickpea (Cicer arietinum L.) (variety: Habru). The experiment was executed as a factorial arrangement using a completely randomized design with three replications. The treatments were control (non‐fertilized), sole AM fungi inoculation, AM fungi inoculation with phosphorus fertilizer (20 kg P ha−1) and MR, and sole inorganic fertilizers (20 kg P;10 kg N ha−1) at four different moisture levels (optimum throughout the growing season, stressed at vegetative, flowering, and seed filling stages). The results demonstrated that biomass yields were limited by moisture stress, especially at vegetative and flowering stages of chickpea. Sole and co‐application of AMF with MR and inorganic P increased biomass yields on average by 19%, 39%, and 33% under water stress conditions, respectively, compared to the non‐inoculated control. The application of AMF with MR and inorganic P also significantly increased nodulation, AMF colonization, and nutrient uptake, but these effects were dependent on soil moisture status. In conclusion, there are potential advantages to be gained from sole and combined AMF application with rhizobium to improve growth and productivity of chickpea through enhanced nutrient and water uptake, though the results of this pot experiment should be validated through field trials.
