Atomically dispersed catalysts, characterized by their high atom utilization efficiency and distinct catalytic activity, exhibit advantages in reducing fuel cell costs. Herein, we synthesized Co/N/C atomic catalysts by acid leaching of CoO/N/C prepared through carbothermal shock. The resulting Co/N/C-130 demonstrates outstanding performance for the oxygen reduction reaction (ORR) in alkaline media. It displays a half-wave potential ( E 1/2 ) of 0.82 V and a Tafel slope of 47.1 mV dec −1 . Furthermore, it exhibits excellent stability with a positive E 1/2 shift of 6 mV after 40,000 cycles. When applied as a cathode catalyst in a direct borohydride fuel cell (DBFC), Co/N/C-130 achieves a maximum power density of 396 mW cm −2 at 60 °C. Long-term durability test at 50 mA cm −2 reveals a power retention of 90.8% after 24 h and 76.3% after 50 h. These results demonstrate that Co/N/C-130 atomic catalyst is a highly efficient and durable non-precious metal catalyst for ORR. Graphical abstract

The pursuit of white light-emitting diodes (WLEDs) with high color rendering index (CRI) and stable chromaticity remains a significant challenge. This work presents a novel oxyapatite-type ZnLa 4 (SiO 4 ) 3 O:Dy 3+ phosphors as a key component to address this issue. Under 387 nm excitation, the optimized ZnLa 4 (SiO 4 ) 3 O:2 mol%Dy 3+ phosphor exhibits intense emissions at 480, 572, and 663 nm, corresponding to the electronic transitions from the 4 F 9/2 level to the 6 H 15/2 , 6 H 13/2 , and 6 H 11/2 levels, respectively. The concentration quenching mechanism is identified as dipole–dipole interaction, with the optimal doping level at 2 mol%. The phosphor demonstrates excellent color stability, emitting in the yellow region. More importantly, the WLED fabricated with this phosphor exhibited a high CRI ( R a = 89), a favorable correlated color temperature (CCT = 5740 K), and CIE (Commission International de L’ Eclairage) coordinates (0.327, 0.334) remarkably close to pure white light (0.333, 0.333). These results underscore the great potential of ZnLa 4 (SiO 4 ) 3 O:Dy 3+ phosphors for high-quality solid-state lighting.

Porous carbon materials have long been a research focus in supercapacitor electrode materials owing to their excellent electrical conductivity, high specific surface area, and good chemical stability. Herein, we propose an approach for the preparation of porous carbon materials using the ice crystal template method combined with carbonization and activation of chitosan and dopamine hydrochloride polymer networks as precursors. The effects of the ratio of precursors to KOH activator on the electrochemical performance of the materials are systematically studied. The results show that the optimized sample exhibited a high specific capacitance of 317.8 F g −1 . Furthermore, the device assembled with this material as the negative electrode and self-made Ni(OH) 2 as the positive electrode delivered energy density of 18.7 Wh kg −1 with capacitance retention of 96% after 10,000 cycles.

This study presents a portable and accurate nitrite detection system that integrates a differential gradient analysis with smartphone-assisted microfluidic colorimetry to improve detection efficiency and precision. A bidirectional concentration gradient was established via diffusion within a PDMS-based microfluidic chip, significantly reducing the dependency on standard calibration and shortening the total detection time to within 15 minutes. Sample images were captured using a smartphone camera, and nitrite concentrations were quantified through RGB color analysis using a custom-developed mobile application. The implementation of the differential colorimetric method significantly improved detection accuracy, particularly at low concentrations, reducing the measurement error from 9.12% (conventional methods) to 1.93%. The platform demonstrates compatibility with various smartphone models, thereby eliminating the need for bulky instrumentation or specialized training. These features collectively enhance its potential for rapid point-of-care testing. Overall, the proposed method offers a cost-effective and efficient solution for quantifying colorimetric-responsive analytes in resource-limited settings. The successful integration of microfluidic technology with smartphone-based analysis not only advances nitrite detection performance but also opens new avenues for detecting other analytes, underscoring its broad applicability in field applications.

In this study, a La-doped flexible hydrophobic Al 2 O 3 fiber membrane was fabricated via electrospinning technology, and the influence of La doping on the mechanical properties and surface wettability of the Al 2 O 3 fiber membrane was systematically investigated. The results showed that the La-doped modified alumina nanofiber membrane has tunable fiber diameters (180–480 nm) and a highly interconnected porous network, which enhanced the efficiency and flux of oil–water separation. The incorporating an appropriate amount of rare earth La atoms, specifically at a La/Al atomic ratio of 0.125 (La-Al 2 O 3 -2), effectively enhanced the flexibility and tensile strength of the membrane. Concurrently, hydrophobic La 2 O 3 formed on the fiber surface, which transformed the membrane from hydrophilic to hydrophobic. As a result, the La-doped Al 2 O 3 membrane exhibited excellent anti-fouling performance, high permeation flux, and efficient oil–water separation. However, excessive La addition led to a significant decline in the flexibility and tensile strength of the Al 2 O 3 fiber membrane, whereas the hydrophobic surface was largely preserved. Among all samples, the La-Al 2 O 3 -2 fiber membrane exhibited superior flexibility and tensile strength. In oil–water separation applications, it achieved a high permeation flux of 2921 L/(m 2 ·h) and a separation efficiency of 98.4%; meanwhile, the good reusability was also obtained. Graphical abstract

The synergistic oxidative and tellurium-induced (Te-induced) corrosion of the fast-reactor candidate 15–15Ti austenitic stainless steel under high oxygen potentials was investigated in this study. Specimens were exposed at 900 K in both Te-free and Te-containing environments, with the oxygen potentials controlled using Mo/MoO 2 and Ni/NiO redox buffers. Under Te-free conditions, a duplex oxide scale formed on 15–15Ti, comprising an Fe-rich outer oxide layer and a Cr-enriched inner oxide layer. In contrast, in the presence of Te, a markedly thicker multilayer reaction scale developed, consisting of four distinct layers arranged from the surface inward: (i) a Mn–O outer oxide layer; (ii) an Fe–Ni–Te metallic telluride layer; (iii) a Cr-enriched outer telluride reaction layer with Cr 3 Te 4 as the dominant phase; and (iv) an inner Te/Cr-enriched reaction layer, in which a phase consistent with Cr 2 Te 4 O 11 was identified. These findings indicate that, under high oxygen potentials, corrosion of 15–15Ti is governed by the coupled action of Te and oxidation. The introduction of Te more strongly promotes outward diffusion of metal cations (especially Fe) and suppresses the formation of a protective Cr-rich oxide layer, thereby markedly accelerating scale thickening and stabilizing the multilayer architecture.

The edible mushroom industry generates substantial agricultural by-products (e.g., Pleurotus ostreatus residues, POR) rich in polysaccharides. This study innovatively applied multiple extraction methods to obtain Pleurotus ostreatus residues polysaccharides (PORPs) for the first time, systematically investigating their physicochemical, structural, functional, and bioactive properties, thereby filling the existing knowledge gap. Among the six PORPs extracted, hot water-extracted PORPs (PORP-H) and hot alkali-extracted PORPs (PORP-B) showed higher yields; ultrasonic-assisted extracted PORPs (PORP-U) and hot water-hot alkali sequentially extracted PORPs (PORP-HB) exhibited distinct functional advantages, thus highlighting the specificity of each method in tailoring PORP characteristics. All six PORPs consisted of 9 monosaccharides, shared analogous functional groups, displayed good thermostability, contained plentiful branched chains, and lacked a triple-helix structure, with molecular weights ranging from 432.50 kDa (PORP-U) to 590.10 kDa (PORP-H). PORP-B showed the strongest in vitro antioxidant activity; acid-extracted PORPs (PORP-A) effectively promoted the proliferation of lactic acid bacteria (LAB), indicating potential prebiotic effects. PORP-H and PORP-HB exhibited superior foaming capacity (FC) (135.25 ± 1.06% and 132.67 ± 2.75%) and foaming stability (FS) (120.25 ± 0.35% and 119.67 ± 0.76%). PORP-U had better water-holding capacity (WHC) (1.42 ± 0.21 g water/g) and emulsifying activity index (EAI) (12.85 ± 0.33 m 2 /g), while PORP-H demonstrated the best emulsifying stability index (ESI) (73.99 ± 2.25 min). These findings demonstrate that PORPs extracted by appropriate methods possess high bioactivity and functional properties, supporting their promising application in functional foods. Graphical

Septic cardiomyopathy (SC) is a severe complication of sepsis that significantly increases patient mortality. The onset of SC is associated with excessive reactive oxygen species (ROS), leading to increased oxidative stress and iron accumulation. Herein, we develop a library of conductive polypyrrole-polythiophene copolymer (PPy- co -PTh)-stabilized nanozymes by coordinating different metal ions within the copolymer framework. From this library, we identify a PPy- co -PTh stabilized ruthenium-based nanozyme (Ruzyme), which exhibits significant catalase- and superoxide dismutase-like activity, as well as nitrogen radical scavenging capability. Modifying the conductive interface significantly improves the catalytic activity and stability of the Ruzyme by lowering the catalytic energy barrier, reducing excessive oxidation caused by ROS, and facilitating the continuous decomposition of ROS. To achieve precise targeted delivery to myocardial mitochondria, (5-carboxypentyl) triphenyl phosphonium bromide (TPP-COOH) and a cardiac-targeting peptide (CTP) are conjugated onto the surface of the Ruzyme. In vitro, the stabilized nanozymes effectively scavenge ROS, reduce iron accumulation, and inhibit iron-dependent cell death, thereby lowering lipid peroxidation. In male SC mice, they improve cardiac function, demonstrating therapeutic benefits. Given the growing interest in nanozymes for cardiovascular diseases, this study provides a potential foundation for the development of therapeutic agents for severe cardiomyopathy and related conditions.

Objective Post-stroke depression (PSD), a common stroke complication, negatively impacts physical function, cognition, and quality of life. Edaravone dexborneol (ED), a combination agent, helps alleviate ischemia-induced damage to neuro-motor and cognitive functions. This study aims to evaluate the neuroprotective effects of ED in a rat model of PSD. Methods The PSD model was established via filament inserting through the internal carotid artery and chronic unpredictable mild stress stimulation. After the model was established, ED treatment was given for 14 days ( i.p. at a dose of 3mg/kg). Subsequently, the therapeutic effects of ED on behavioral parameters and inflammatory biomarkers in the PSD rats were analyzed. Results ED has a tendency to increase the percentage of sucrose preference in PSD rats. ED could significantly shorten the forced swimming time of PSD rats ( P < 0.05). ED significantly increased the level of 5-hydroxytryptamine in the brain tissue of PSD rats ( P < 0.05) and reduced the expression of inflammatory markers interleukin-6 and tumor necrosis factor-α ( P < 0.05). Conclusion ED demonstrates potential therapeutic efficacy in mitigating depressive-like behaviors in a PSD rat model, reducing neuroinflammation, minimizing brain tissue damage, and conferring neuroprotective benefits.

To investigate the role of IL-17 in macrophage M1 polarization within a type 2 diabetic (T2DM) milieu and to evaluate the therapeutic potential of its neutralizing antibody. PMA-differentiated THP-1 macrophages were polarized to M1 state. Under high glucose, cells were treated with IL-17 and an IL-17 neutralizing antibody. Inflammatory cytokines (IL-1β, IL-6, TNF-α) were measured; mRNA levels of TNF-α, HIF-1α, and NLRP3 were assessed by qPCR; and protein expression related to the NF-κB, mTOR/HIF-1α axis and pyroptosis (NLRP3, Caspase-1, GSDMD) was analyzed by Western Blot. High glucose and IL-17 synergistically promoted M1 polarization, enhancing proinflammatory cytokine secretion. This was associated with activation of the NF-κB, mTOR/HIF-1α signaling axis and induction of pyroptosis, evidenced by NLRP3 inflammasome assembly, Caspase-1 activation, and GSDMD cleavage. The IL-17 neutralizing antibody effectively suppressed these pathological processes. IL-17 acts as a key immunological amplifier in diabetes, driving M1 polarization, oxidative stress, and pyroptosis via the NF-κB, mTOR/HIF-1α axis and NLRP3 inflammasome. Treatment with an αIL-17 effectively reversed the aberrant activation of the aforementioned cellular phenotypes and signaling pathways, partially restoring macrophage functional balance. This finding provides preliminary experimental support for further exploration of IL-17-targeted immunomodulatory strategies to ameliorate diabetes-associated metabolic inflammation.

Objectives The current treatments of polycystic ovarian syndrome (PCOS) have limited selectivity and effectiveness. Zishen Yutai Wan (ZSYTW) has shown therapeutic effects on patients with PCOS. This study aims to discover potential therapeutic targets and molecular mechanisms based on network pharmacology and molecular docking. Methods A disease gene set related to PCOS was collected from three public databases, a ZSYTW target gene set was established using the Traditional Chinese Medicine Systems Pharmacology database and Traditional Chinese Medicine and Chemical Components Database, and an intersection of two gene sets to obtain intersecting genes. Protein-protein interaction (PPI) network were performed on intersecting genes. Molecular docking further confirmed the high affinity and stability between the active compounds of ZSYTW and core targets. Finally, PCOS model mice were used to verify the results. Results Network pharmacology showed that AKT1 , TNF , IL6 , TP53 , and ESR1 were the key targets of ZSYTW against PCOS. Molecular docking demonstrated beta-sitosterol and stigmasterol exhibit strong binding affinities and binding stability with core targets, and p53 has the highest affinity with core components of ZSYTW. Mice experiment showed that compared with the control group, the expression of p53 protein and total apoptosis rate of ovarian granulosa cells in PCOS group were significantly increased ( P < 0.001). And ZSYTW could decrease the increased expression of P53 protein and total apoptosis rate of granulosa cells ( P < 0.001). Conclusion ZSYTW could effectively improve PCOS by regulating p53 and apoptosis of ovarian granulosa cells.

In this research, low-frequency alternating magnetic field (LF-AMF, 5 mT, 1–5 h) was used to investigate the effect on the structural, rheological, and gel properties of porcine myofibrillar protein (MP) under low-salt condition (0.3 M NaCl). The solubility, surface hydrophobicity, active sulfhydryl content, intrinsic fluorescence intensity, water holding capacity (WHC), and gel strength of low-salt porcine MP exhibited a trend of initial increase followed by a subsequent decrease as the LF-AMF processing time extended ( P < 0.05). Furthermore, LF-AMF treatment could induce an elevated β-sheet proportion, G’ value and a reduced α-helix proportion, suggesting that LF-AMF facilitated the improvement of gel attributes in low-salt porcine MP. Meanwhile, LF-AMF could trigger the construction of a homogeneous and tight MP gel network, resulting in bounding of more water molecules, which elevated the percentage of immobilized water and diminished the percentage of free water. Thus, an appropriate LF-AMF processing time can effectively improve the gel characteristics of low-salt porcine MP.
