Semiconductor photocatalysis offers an environmentally sustainable approach for the elimination of organic contaminants from wastewater. However, the photocatalytic performance of Zn 2 In 2 S 5 (ZIS) is often limited by nanosheet aggregation, insufficient exposure of active sites, and the incomplete understanding of reactive oxygen species (ROS) evolution. In this study, marigold-like ZIS microspheres with a 2D-3D hierarchical porous structure were fabricated, and their performance in the photocatalytic degradation of rhodamine B (RhB) was investigated. The structural and physicochemical properties of the obtained ZIS were systematically investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), UV–Vis diffuse reflectance spectroscopy (DRS), and Mott–Schottky analysis. The results demonstrated that this unique structure integrates the advantages of the short charge migration distance of 2D materials and multiple light scattering/adsorption sites of 3D structures. Under AM 1.5 simulated sunlight irradiation, the as-prepared ZIS photocatalyst exhibited excellent photocatalytic activity, with a RhB degradation efficiency of up to 99.7% within 60 min and an apparent reaction rate constant (k) of 0.09 min⁻ 1 , which compares favorably with most previously reported ZIS-based photocatalysts. Through trapping experiments, electron spin resonance (ESR) spectroscopy and qualitative detection of hydrogen peroxide (H 2 O 2 ), the photocatalytic reaction mechanism of ZIS was elucidated: superoxide radical (·O 2 − ) is the primary active species, followed by photogenerated hole (h⁺), whereas hydroxyl radical (·OH) make the least contribution. More importantly, a cascade mechanism of “ O 2 − – H 2 O 2 –·OH” was proposed in this work, which not only resolves the inherent contradiction of insufficient valence band position of ZIS but also demonstrates the potential of hierarchical zinc indium sulfide photocatalysts for efficient environmental remediation applications.

The increasing demand for high-energy-density batteries pushes practical aqueous Zn-based batteries. However, high Zn utilization achieved in coin symmetric cells is unable to translate to full cells, especially large pouch cells, due to the poor reversibility of Zn and capacity output of high-loading positive electrodes. Here, solid-solid interfacial conversion mechanisms via chelation at electrodes-electrolyte interfaces effectively suppress parasitic reactions being widely prevalent under traditional solid-liquid conversion mechanisms. Consequently, high Zn utilization ( ≥ 78.3%) is unified across coin symmetric, coin full and pouch full cells. The Zn | |I 2 pouch cell (10 cm×10 cm) demonstrates a specific energy of 116.8 Wh kg −1 (based on total mass) and over 850 cycles (85.1% capacity retention) at 10 mA cm −2 . Furthermore, solid-solid interfacial conversion mechanisms exhibit universality across halogen positive electrodes, advancing practical aqueous Zn | |halogen batteries.

Background Effective diagnoses and treatments for liver fibrosis (LF) are lacking. The gut microbiota (GM)–bile acid (BA) axis is critically associated with LF development and may represent a potential target for delaying or reversing LF. Methods We combined fecal microbiomics and BA-targeted metabolomics to characterize the GM–BA axis in rats with carbon tetrachloride (CCl₄)-induced LF and used fecal microbiota transplantation (FMT) and probiotics (Bifidobacterium quadruple viable tablet solution) to regulate the GM–BA axis to investigate the role of the GM–BA axis in LF and its related mechanisms. Results The GM composition and GM β-diversity differed significantly between the control and model rats. Clostridia and others were significantly increased, whereas Bifidobacteriales and others were significantly decreased in model rats. Serum BA metabolism differed significantly between the groups. The concentrations of 19 BAs were significantly increased in model rats. FMT improved the disordered GM by increasing Bifidobacteriales and others and decreasing Clostridia and others. Probiotics improved the disordered GM by decreasing Clostridia, Lachnospiracea_incertae_sedis and others. FMT and probiotics improved BA metabolism by decreasing BAs such as tauroursodeoxycholic acid (TUDCA). FMT and probiotics were associated with a reduced degree of LF in model rats. Conclusions The GM–BA axis is strongly associated with LF, and the use of FMT and probiotics may contribute to regulating the GM–BA axis and to alleviating LF. Graphical

Aging is a major risk factor for neurodegenerative diseases, including Alzheimer’s disease (AD). Targeting cellular senescence has therefore emerged as a promising therapeutic strategy. Resveratrol (RV), a natural polyphenolic compound, exhibits anti-aging properties through the regulation of autophagy and oxidative stress; however, its mechanisms in AD remain incompletely understood. In this study, we investigated the effects and underlying mechanisms of RV in an Aβ1–42-induced AD model. In vivo, RV administration significantly reduced the expression of aging-related markers and activated autophagy-associated signaling pathways. In vitro, RV treatment markedly attenuated Aβ1–42-induced cell viability loss and excessive reactive oxygen species (ROS) production. Further mechanistic analyses demonstrated that RV-induced autophagy activation was closely associated with the AMP-activated protein kinase/UNC-51-like kinase 1 (AMPK/ULK1) and silent information regulator 1/nuclear factor-kappaB (SIRT1/NF-κB) pathways. Collectively, these findings suggest that RV alleviates AD-related pathological processes by promoting autophagy and delaying cellular senescence, highlighting its potential as a therapeutic agent for age-related neurodegenerative diseases.

Aqueous Zn | |I 2 batteries, involving I - /I 0 /I + redox, are promising yet usually facing low I 2 utilization dominated by I 0 /I + redox, especially under high loadings. Unlocking alternative pathway to I 0 /I + redox, preferably in noncorrosive dilute electrolytes, is a crucial solution. Here, we report a pathway towards more thermodynamically favorable I 0 /I + redox, via a unique carbon-halogen bond substitution. This pathway is realized with a low-concentrated (0.7 M), noncorrosive organohalide additive (2-bromoacetamide, BrAce), triggering a reversible Br-C···I (0) and C-I (+) -Br bond substitution. Compared with conventional interhalogen bonding (I-Br) pathway, this pathway synchronously lowers the barrier for I⁰/I⁺ redox and strengthens the anti-hydrolysis of I + species, by elaborately regulating axial δ hole activity of interhalogen bond (I (δ+) -Br). Notably, this pathway enables sustainable operation of four-electron Zn | |I 2 batteries with high I 2 loading (8.6 ~ 24.0 mg cm -2 ), featuring improved performances: (1) high I 2 utilizations (55% ~ 80%) at high rates (5.8 ~ 46.4 mA cm -2 ), (2) long lifespan ( \( > \) 400 cycles) with practical areal capacity ( ~ 3.85 mA h cm -2 ) and 99.5% retention even at 47.5 mA cm -2 . This pathway opens an exciting research direction to unlock unusual halogen chemistry for scalable, high-energy, sustainable aqueous batteries.

Lactic acid bacteria (LAB) are commonly used to degrade nitrite in dry fermented sausages. However, the impact of nitrite-degrading LAB on flavor formation and its regulatory effects on the microbial community, free amino acid (FAA), and lipid metabolism associated with flavor development are not yet fully understood. This study investigated the effects of Lacticaseibacillus rhamnosus H7—a nitrite-reducing strain—on the microbial community, flavor compounds, and metabolites using multi-omics and FAAs analysis. Results showed that the inoculation of Lcb. rhamnosus H7 became dominant, promoted the release of FAAs, and enhanced the accumulation and transformation of specific lipids (e.g., PE, TG, and PC). Correlation analysis revealed that Lcb. rhamnosus H7 was positively associated with the abundance of Weissella hellenica and Weissella minor . This might be further linked to enhanced amino acid and lipid metabolism, which coincided with the increased formation of key flavor compounds such as hexanoic acid and ethyl 2,4-hexadienoate. Overall, this study demonstrates that the inoculation of Lcb. rhamnosus H7 can modulate microbial structure and promote amino acid and lipid metabolism, improving the content of characteristic flavor compounds. This study also provides a reasonable hypothesis for the potential mechanism by which LAB regulate the flavor of low-nitrite dry fermented sausages.

As crucial biomarkers, the rapid and sensitive detection of dopamine (DA) and uric acid (UA) is essential for disease prevention and diagnosis. In this study, MoS 2 /MoO 2 heteronanorod modified N-doped porous carbon nanofiber (N-PCNFs@MoS 2 /MoO 2 ) sensing electrodes for the simultaneous detection of DA and UA were fabricated by electrostatic spinning coupled with vulcanization reaction. The carbonization treatment of the ZIF-8/PAN precursor endows material with hierarchical pores and a highly conductive network, which significantly increases the specific surface area and active sites and provides a fast electron transport channel for electrochemical reactions. Moreover, the synergistic effect of MoS 2 /MoO 2 optimizes the ion transport pathway and further enhances the electrocatalytic performance. Experimental results show that the electrode exhibites excellent performance for the simultaneous detection of DA and UA. The linear range for DA detection is 0.5–35 µM with a limit of detection (LOD) of 0.038 µM (S/ N = 3), while UA shows a two-segment linear response with linear ranges of 1–20 µM and 20–110 µM, respectively, and a LOD of 0.245 µM (S/ N = 3). This electrode is capable of realizing the simultaneous detection of DA and UA in human serum, showing a broad application prospect in the field of biosensing.

Conductive hydrogels represent a pivotal advancement for next-generation wearable electronics. However, simultaneously optimizing mechanical robustness, interfacial adhesion, and electromechanical sensitivity remains a significant challenge. In this study, a multifunctional poly(vinyl alcohol)/chitosan/multi-walled carbon nanotube (PCM) composite hydrogel was developed via a facile freeze-thaw strategy. The resulting PCM hydrogel exhibits reliable adhesive strength (12.1 kPa on porcine skin) with over 70% retention after 10 cyclic attachment-detachment tests. Notably, the hydrogel possesses a high electrical conductivity of 13.2 mS/cm, enabling superior sensing performance with a Gauge Factor (GF) of 5.72 under large strains and excellent durability over 500 cycles. Real-time monitoring of human joint motions (e.g., wrist, finger, and elbow) confirms its rapid response and high signal fidelity. These results underscore the potential of PCM hydrogels as a robust and high-performance interface for sophisticated human-machine interaction and sports health monitoring.

Blends of soy proteins isolate (SPI) and insoluble dietary fiber (IDF) are promising due to their ability to produce fibrous products resembling meat texture. In this study, model blends of SPI-IDF (SPI: IDF = 90:10, based on dry mass) with varying proportions of soluble (SSPI) and insoluble SPI (ISPI) were produced through high-moisture extrusion. The rheological behaviors of the SPI-IDF blends, as well as the morphology and mechanical properties of the extrudates, were investigated. The results showed that the ISS-40 extrudate (ISPI: SSPI = 4:0) exhibited pronounced fibrous structures with superior mechanical anisotropy. This was attributed to the even distribution of numerous small-sized voids or honeycomb areas, which were deformed along the extrusion flow direction. In contrast, ISS-04 extrudate (ISPI: SSPI = 0:4) exhibited a gel-like structure with the coalescence of IDF domains. These morphological and mechanical differences were attributed to the viscoelastic properties of protein matrix, which affected the distribution of dispersed IDF domains. Thus, these insights into the interactions between the continuous and dispersed phases in SPI-IDF blends provide guidance for developing meat analogue products with desired textural properties.

Two-dimensional (2D) materials hold promise for miniaturized photodetectors. With ample exciton resonances, the photodetection range of transition metal dichalcogenides (TMDCs) can be further extended to long wavelengths on a large scale by two-photon absorption (TPA), breaking the limit of their bandgaps. However, the conversion efficiency of TPA usually remains low despite resonant nonlinear optical effects. Here, we present a plasmonic metasurface-enhanced 2D TMDC photodetector by means of high-order multipoles with anapole states, as well as quasi-bound states in the continuum, operating efficiently in the near-infrared second (NIR-Ⅱ) window at room temperature. The optical response of the MoS 2 /WSe 2 heterostructure is simultaneously enhanced by the interlayer exciton resonances and by the hot carrier injection from the plasmonic metasurface. By optimizing the metasurface design, the responsivity can reach 1.35 A/W at 1550 nm, which is ~5 × 10 4 times larger than that of a MoS 2 /WSe 2 heterostructure on SiO 2 /Si substrate. Furthermore, the broken mirror symmetry of the structure enables a chiral photoelectric response with discrimination ratios up to 7.2. Our study offers a promising platform for applications in NIR-Ⅱ bio-imaging, telecommunication, and on-chip spectroscopic sensing.

Gel-based flexible wearable sensors have attracted considerable interest in aquatic environments. However, the development of underwater conductive gel sensors with outstanding anti-swelling, mechanical, and sensing capabilities faces significant challenges. The aim of this study is to develop anti-swelling and conductive zwitterionic gels and investigate their applications in wireless underwater strain sensing. Multi-functional zwitterionic gels were fabricated by copolymerizing [2-(methacryloyloxy) ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide (SBMA) and acrylic acid (AA) in a mixed solution of aluminum chloride (AlCl 3 ) and poly(vinyl alcohol) (PVA) under ultraviolet light (360 nm). PSBMA was switched from a neutral polymer to a positively charged polymer because of the combination of Al 3+ with the negative groups SO 3 − . The water molecules were eliminated because of electrostatic repulsion. The gels exhibited anti-swelling properties (swelling ratio <11%), high stretchability (600% strain), and toughness (2451 kJ/m 3 ). The PPAS-Al 3+ gel was integrated with a wireless Bluetooth system to construct underwater wearable strain sensors that could accurately capture the signals caused by human joint movements and speech recognition even in water. Antibacterial activity (>98.9% inhibition) and stable wireless sensing have potential applications in the fields of wearable sensors, underwater communication, and intelligent healthcare.

The development of solar-driven interfacial evaporation technology is pivotal for addressing global water scarcity. However, it is hindered by the difficulty in synergizing high photothermal conversion with low water evaporation enthalpy into a single material. Herein, we propose an iron-aldehyde-cooperative dynamic covalent anchoring strategy, successfully constructing a covalently locked, hydroxymethyl-functionalized PEDOT-PVA integrated dual-network hydrogel (MEPH). This strategy employs Fe 3+ to achieve the one-step in situ oxidative polymerization of hydroxymethyl EDOT while concurrently forming a physical hybrid network with PVA, which is subsequently reinforced by covalent cross-linking using glutaraldehyde. This design endows the MEPH with exceptional broadband light absorption (>99%), efficient water transport, and regulated water state within the hydrogel matrix, leading to a reduced evaporation enthalpy of 732 J·g −1 . The resulting evaporator achieves an ultrahigh evaporation rate of 4.95 kg·m −2 ·h −1 under 1-sun illumination, corresponding to an energy conversion efficiency exceeding 95%, while maintaining stable, salt-resistant operation in high-salinity environments. Outdoor experiments validate its outstanding practicality for seawater and wastewater purification, with the produced freshwater significantly promoting plant growth, highlighting its great potential in sustainable agricultural water cycles. This iron-aldehyde-cooperative dynamic covalent anchoring strategy provides an innovative design paradigm for a new generation of high-performance and robust solar evaporators.
