Heterogeneous catalytic ozonation can effectively degrade the contaminants in wastewater due to the strong oxidizing hydroxyl radicals (HO•) are produced in the catalytic ozonation. Although the porous ceramsite features a large specific surface area, good physical strength, and a stable chemical composition, it suffers poor stability and a low HO• generation efficiency. Herein, CuCe doped ceramsite (CuCe@Ceramsite) was successfully prepared by the wet impregnation, alkali precipitation and post-calcination method. Compared to the O 3 and single metal doped ceramsite/O 3 processes, a higher degradation and mineralization efficiency for the benzotriazole (BTA) oxidation in the CuCe@Ceramsite/O 3 process is obtained under optimal conditions, which could be attributed to the enhanced production of HO•. Numerous tests (i.e., electron paramagnetic resonance (EPR), radical quenching experiments) confirm that the oxidation of BTA is predominantly governed by O 3 and HO•, whereas O 2 •− and 1 O 2 play a minor role. Furthermore, the addition of SO 4 2− , Cl − , NO 3 − , and humic acid (HA) does not exert any discernible influence on the degradation of BTA in the CuCe@Ceramsite/O 3 process, whereas HCO 3 − /CO 3 2− promotes the oxidation of BTA. Additionally, CuCe@Ceramsite demonstrates remarkable catalytic performance for BTA oxidation in recycling tests. As a result, CuCe@Ceramsite has the potential to remove refractory pollutants via the catalytic ozonation. Graphical

Phytosterol (PS) face challenges of poor stability and rapid release in the gastrointestinal tract. To overcome these limitations, this study developed whey protein-chitosan composite (WP-CS-PS) nanoparticles via reverse solvent precipitation, significantly enhancing PS transport efficiency and functional performance. Through systematic optimization using single-factor and orthogonal tests, the nanoparticles were fabricated under ideal parameters. The optimal conditions included a 1:1 WP/CS mass ratio, 0.8% (w/v) PS concentration, 60 °C hydration, and 15 min stirring, which yielded high encapsulation efficiency (77.43%), uniform particle size (203.41 nm, PDI 0.265), and excellent colloidal stability (zeta potential − 35.42 mV). Structural analyses (SEM, FT-IR) revealed a dense gel-network morphology with PS successfully embedded via hydrogen bonding and electrostatic interactions. The WP-CS matrix markedly improved PS stability against thermal, UV, and storage stresses, while in vitro digestion assays demonstrated sustained intestinal release (17.72% slower than free PS). These results not only validate WP-CS-PS as a robust carrier for lipophilic bioactives but also offer a scalable strategy to enhance the bioavailability of PS in functional foods, potentially addressing global health needs such as cholesterol management and dietary supplementation. By bridging material science and nutritional delivery, this work paves the way for sustainable nutraceutical innovations with broad industrial applicability. Graphical

Coating Ni-rich layered oxide positive electrodes is essential to improve their electrochemical performance in sulfide-based all-solid-state Li batteries, but achieving cost-effective, high-performance positive electrodes remains challenging. In this work, we apply a thin (~3 nm) conductive binary Li borate glass coating (0.5Li 2 O·0.5B 2 O 3 ) onto single-crystal LiNi 0.8 Co 0.1 Mn 0.1 O 2 using a simple dry process and heating. This coated positive electrode delivers 209 mAh g −1 specific capacity at a specific current of 20 mA g −1 with 79.7% initial Coulombic efficiency, retains 87.8% capacity after 1000 cycles at a specific current of 200 mA g −1 , and achieves 14.6 mAh cm −2 areal capacity. Pouch cells with this positive electrode reach 383 Wh kg −1 specific energy, and sustain 300 cycles at a specific current of 66.67 mA g −1 . Various characterizations reveal that this coating can enhance Li-ion transport, stabilize the positive electrode lattice, and strengthen the interface between positive electrode and sulfide electrolyte. Here we show that conductive glass coatings enable high-voltage positive electrodes with high stability and specific energy in all-solid-state batteries.

Background and Aims Sulfur (S) decreases arsenic (As) accumulation in crops, yet its mechanism and applicability to other plants remain unclear. This study investigated the role of S in As behavior in lettuces ( Lactuca sativa L.) and evaluated S application in leafy plants, focusing on As complexation. Methods Plants were stressed with arsenate (AsV) and dimethylarsinic acid (DMA) under three different S supplementation (0, 1, and 3 mM) in hydroponic culture. As species, As-phytochelatins, ascorbate–glutathione (AsA-GSH) cycle enzymes and mineral elements in plants were analyzed. Results The effect of S was As-species-dependent. Specifically, under AsV stress, 3 mM S significantly decreased As content by 20.8% in leaves and As translocation factor (TF) by 17.4%, while root As (230–252 mg/kg, dry weight) and As-phytochelatins (1.02–1.27 mg/kg, fresh weight) remained unaffected, which is contrary to other reports. In terms of As species, leaf arsenite (AsIII) content and TF-AsIII were decreased, but AsV and root AsIII content were not significantly changed. Under DMA stress, 3 mM S significantly decreased As content by 17.7% in roots but did not alter leaf As content. The root DMA was significantly decreased, while monomethylarsonic acid (MMA) and leaf DMA content were unchanged. Additionally, exogenous S regulated root AsA-GSH cycle over leaves under both As stresses and increased leaf Fe and Zn accumulation. Conclusions Exogenous S inhibited AsV and DMA uptake, suppressed AsV-to-AsIII conversion and AsIII transfer to leaves, and facilitated DMA-to-MMA conversion, highlighting its potential applications in agriculture to restrict As in leaves on contaminated lands.

Objective To elucidate the modulation mechanism of Suanzaoren Decoction (SZRD) on basolateral amygdala (BLA) neuronal activity to alleviate chronic restraint stress (CRS)-related behavioral deficits. Methods The male C57BL/6J mice were assigned to 4 groups using the complete randomization method, including control (CON, n =19), CRS ( n =19), SZRD ( n =21), and fluoxetine (Flu, n =22) groups. Mice were restrained for 6 h per day, over a 21-d period to establish CRS models. The CON group remained in their cages without food or water during the 6-h matching period. SZRD and Flu groups received intragastric administration of SZRD (4.68 g/kg) and Flu (20 mg/kg) daily, respectively, 30 min before restraint for 21 consecutive days. The therapeutic effects of SZRD were evaluated using behavioral tests including the tail suspension test, elevated plus maze test, and forced swimming test. The cellular Fletcher B. Judson murine osteosarcoma proto-oncogene (c-Fos) expression in the BLA was measured using immunofluorescence, while action potential (AP) firing and synaptic transmission in BLA pyramidal neurons were evaluated using whole-cell patch-clamp recordings. Results SZRD administration significantly increased time spent in the open arms and open-arm entries while reducing immobility time ( P <0.05 or P <0.01). It downregulated CRS-induced c-Fos expression and AP firing of pyramidal neurons in the BLA ( P <0.01). Additionally, SZRD selectively attenuated excitatory ( P <0.01), but not inhibitory, synaptic transmission onto BLA pyramidal neurons. Conclusion SZRD alleviated CRS-induced anxiety- and depression-like behaviors in mice by modulating the excitability and synaptic transmission of BLA pyramidal neurons.

Emulating biological synaptic plasticity is essential for advancing artificial intelligence. However, in most existing synaptic phototransistors to date, both electrical and optical stimuli induce weight modulation within a comparable dynamic range, limiting plasticity tunability and richness. Here, we report a synaptic phototransistor that enables distinct weight modulation in response to electrical and optical inputs, achieving hierarchical, multi-scale plasticity with concurrent visible-light emission for direct display. The device integrates a long-afterglow material that converts transient ultraviolet (UV) excitation into persistent visible emission, serving as a temporally extended, memory-like optical stimulus. Compared to direct electrical gating, this delayed optical activation of the optoelectronic channel induces weight modulation on a significantly longer timescale, enabling hierarchical plasticity and cascade interactions between optical and electrical pathways. The dual-output architecture allows simultaneous optical visualization and electrical signal processing, effectively integrating optical perception with insensor computation. Leveraging this design, we demonstrate a UV-resolvable neural network capable of direct image display and achieving a recognition accuracy of 95.03% for handwritten digits. This work establishes a new paradigm for multimodal neuromorphic systems by seamlessly integrating sensing, display, and computation within a unified in-sensor architecture.

In this study, borosilicate glasses with different ZrO 2 contents were synthesized at 1200 °C and used to immobilize simulated TRPO waste. The effects of ZrO 2 content on the solid solution limit, microstructure, mechanical properties, and chemical stability of the solidified bodies were systematically analyzed. The results showed that with the increase of ZrO 2 content, the solid solution limit of TRPO waste increased from 20 to 30 wt%, and the degree of amorphization of the solidified bodies could be improved. The addition of ZrO 2 raised the number of bridging oxygen bonds in the solidified body and enhanced the degree of polymerization of the glass structure. For samples containing 4 wt% ZrO 2 , the highest Vickers hardness and density values were 6.57 GPa and 2.89 g cm −3 . Moreover, the 42-day normalized leaching rates of Ce, Nd, La, and Pr in the solidified bodies were about 10 −5 g m −2 d −1 . This work provides useful ideas for the optimization of the solidification matrix materials for high-level radioactive waste. Graphical abstract

Sr 0.7 Bi 0.2 TiO 3 (SBT) relaxor ferroelectric and hydroxyethyl cellulose (HEC) are simultaneously added into the bacterial cellulose (BC) matrix, aiming to enhance the output performance of BC-based triboelectric nanogenerators (TENGs) in this work. The optimum open-circuit voltage and short-circuit current reach 1320 V and 36.12 µA, respectively, generating a high-area output power of 7.14 W/m 2 in the BC/SBT/HEC composites-based TENGs. The optimum power density is separately about 2.27, 1.56, and 1.32 times as high as that of pure BC-TENGs, BC/SBT-TENGs, and BC/HEC-TENGs, which is also better than those of TENGs using similar triboelectric layers. The output improvement can be ascribed to the dual modulation of dielectric constant as well as surface potential. This work offers a synergistic solution to design high output-performance cellulose-based TENGs.

The treatment of rare earth element tailings (REEs) wastewater, a problematic byproduct of rare earth mining processes, presents substantial environmental challenges owing to its characteristic combination of high ammonia nitrogen (NH 4 + -N) concentrations, low organic matter content, and strong acidic conditions. Conventional biological and physicochemical treatment methods exhibit limited efficacy in addressing this complex matrix. To overcome these limitations, this study developed an advanced electrocatalytic oxidation system for NH 4 + -N removal from REEs wastewater pretreated by coagulation-sedimentation. The experimental configuration of system employed a small reactor featuring titanium (Ti) plates coated with thin film layer of high-valent metal oxides. Through systematic parameter optimization, the optimal treatment envelope was established: pH range of 8.5~9.5, electrolysis duration of 35~40 minutes, and catalyst loading ≥ 100 mg/L. Under optimized conditions, the system demonstrated exceptional performance with sustained NH 4 + -N removal efficiency > 99%. Notably, process robustness was confirmed through sensitivity analysis showing minimal performance variation across temperature fluctuations (10~40°C) and initial NH 4 + -N concentration (83.47~368.25 mg/L). Scale-up validation at pilot scale (100 m 3 /d) achieved further comprehensive removal of contaminants including chemical oxygen demand, total phosphorus, NH 4 + -N, and total nitrogen. Full-scale implementation at a REE processing facility in Wuping County, Fujian Province (200 m 3 /d capacity) demonstrated consistent performance over 12-month operation, maintaining NH 4 + -N effluent concentrations below 2 mg/L (99% removal). Techno-economic analysis revealed competitive operational costs of 0.8178 $/m 3 , with energy consumption accounting for 25.8% of total expenditure. These findings suggested that electrocatalytic oxidation technology holds significant potential for full-scale implementation in the treatment of REEs wastewater, providing an effective and sustainable solution for managing NH 4 + -N contamination.

Amorphous sodium zirconium phosphate (NaZrP) with the formula Zr(HPO 4 ) 0.66 (NaPO 4 ) 1.34 ·H 2 O exhibits superior Sr 2+ adsorption capacity (221.85 mg/g) driven by a chemisorption-dominated ion-exchange mechanism. Structural characterization confirms that the amorphous matrix of NaZrP provides accessible active sites (= ZrO 2 POONa/ = ZrO 2 POOH), while kinetic and thermodynamic analyses reveal rapid adsorption kinetics (99% Sr 2+ removal within 5 min) and an endothermic, spontaneous process (ΔG = − 36.56 kJ/mol). In simulated lake water containing competing ions (Na + /K + /Ca 2+ /Mg 2+ ), NaZrP retains 69.10% Sr 2+ uptake efficiency, demonstrating the practical potential for 90 Sr immobilization across diverse aquatic systems.

Dual-ion batteries have got significant attention in recent years due to their efficient ion insertion mechanism, abundant electrode material options, and chemical stability, showcasing advantages such as high operating voltage, low cost, and enhanced safety. Organic electrode materials are often used in dual-ion batteries due to their designability and high theoretical capacity. However, the compatibility between organic electrode materials and current collectors affects the cycling and capacity performance of dual-ion batteries. In this paper, a novel thin film structure of sulfuric acid-doped polyaniline composite copper oxide is electropolymerized on the surface of copper foil current collector. The synergistic effect of electropolymerization-driven oxidation and copper oxide templating facilitates the formation of doped polyaniline nanoparticles, transforming the polymer into long-range ordered crystalline structures with a particle size of 10 nm. Because of the crystalline nanostructure of doped polyaniline and copper oxide, there is an interface change between the anode and active material during charge–discharge cycles, reducing the internal charge transfer resistance from 112 to 40 Ω. While the dual-ion battery shows a significant improvement at high rates, experiments show that the dual-ion battery still retains a capacity of 44 mAh g −1 after 2000 cycles at 5 C, with a capacity retention rate of 69.7%, but the capacity of dual-ion battery without the modification current collectors is only 12 mAh g −1 after 2000 cycles at 5 C. The paper discusses the mechanism of the smallest size composite polyaniline material and the influence mechanisms on the performance of dual-ion batteries. Graphical

Background Irinotecan (CPT-11) is a standard first-line chemotherapy treatment for colorectal cancer (CRC). However, its clinical application is often comprised by gastrointestinal toxicity and limited therapeutic efficacy. Our previous study has revealed that the combination of Vardenafil (Vard) and Linagliptin (Linag) significantly alleviated CPT-11-induced intestinal toxicity in both in vitro and in vivo models. It remains unclear whether this combination can synergistically enhance the anticancer activity of CPT-11. Methods The in vitro synergism of Vard, Linag, and CPT-11 was assessed using cell viability assays on CRC cell lines, including HCT116, SW620, and HT29. An in vivo xenograft mouse model was established to evaluate the drug efficacy of both the original and liposomal forms of Vard and Linag combined with CPT-11. Additionally, untargeted metabolomics was utilized to explore the potential mechanisms underlying the observed synergistic effects. Results In vitro , the combination of Vard and Linag synergistically enhanced the anticancer activity of CPT-11 in CRC cell lines. In vivo , liposomal formulations of Vard and Linag tended to accumulate at the tumor site, improving drug targeting and synergistically enhancing the anticancer efficacy of CPT-11. Untargeted metabolomics analysis revealed that this synergistic effect was probably mediated through the regulation of lysophospholipid metabolism. Conclusion Liposomal Vard and Linag combined with CPT-11 demonstrated a synergistic anti-CRC effect, offering valuable insights into novel combination therapies in CRC treatment. Graphical
