All-soluble all-iron redox flow batteries (RFBs) are among the most promising energy storage technologies due to their low cost, dendrite-free operation, and decoupled capacity and power. In particular, the Fe(TEA) 3+/2+ redox couple has attracted significant attention owing to its appropriate redox potential, fast kinetics, and excellent reversibility. However, the instability of Fe(TEA) chelates, caused by the competitive adsorption of free TEA ligands, remains a major challenge that limits cycling stability and energy efficiency. Herein, we propose a green and efficient strategy to fabricate Nitrogen-doped graphite felt (N@GF) as the anode for the Fe(TEA)-based system and identify the optimal doping concentration. The abundant nitrogen-containing functional groups endow the felt with synergistic electronic modulation and surface coordination capabilities, enabling selective Fe(TEA) complexation while suppressing the undesired adsorption of free TEA ligands by occupying the limited active sites. This tailored interfacial regulation stabilizes Fe(TEA) complexes and enhances charge-transfer efficiency. As a result, the battery employing 5 %N@GF as the anode operates stably for over 950 deep charge–discharge cycles (near 260 h) at 80 mA cm −2 , exhibits significantly reduced polarization compared to pristine GF, achieves a peak energy efficiency above 78 % and a capacity utilization exceeding 83 %. This work offers an eco-friendly and effective material design strategy for improving both the energy efficiency and cycle life of all-soluble all-iron redox flow batteries.

In this study, ZnO quantum dots (QDs) and urea are concurrently incorporated into a polyethylene oxide (PEO)-based solid-state electrolyte via a solution casting method. The ZnO QDs effectively diminish the crystalline regions of PEO, while urea establishes an extensive hydrogen-bonded network within the electrolyte. The hydrogen-bonded network not only mitigates the strong coordination between PEO and Li + , but also enhances the mechanical properties of the electrolyte. Based on this, the solid-state electrolyte and its corresponding batteries exhibit remarkable electrochemical performance. At 60 °C, the solid-state electrolyte exhibits an ionic conductivity of 2.54 mS cm −1 . The Li//Li battery demonstrates stable cycling performance over 1900 h, whereas the LiFePO 4 //Li battery maintains cycle stability for 2000 cycles. Furthermore, the LiFePO 4 //Li battery can operate stably at 45 °C, exhibiting excellent electrochemical performance.

Ultra-high-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS/MS) was used to detect the metabolites during the withering process of rose white tea to find out the differential metabolites, and headspace solid-phase microextraction–gas chromatography–mass spectroscopy (HS–SPME–GC–MS) was used to detect flavor compounds during the withering process of rose white tea and identify characteristic aroma compounds. By studying the flavor characteristics during the withering process, the reasons for the formation of the aroma of rose white tea can be revealed, providing a theoretical basis for the development of new tea products. There was a significant positive correlation (p<0.05) between total flavonoids and benzoids, organoheterocyclic compounds. The contents of compounds such as linalool, trans-cinnamic acid, L-phenylalanine, tyramine, indole-3-acrylic acid, and valine gradually rose during withering, yet declined subsequent to drying. The moisture content, total phenol content, and hydroxyl radical scavenging activity showed a negative correlation with the withering time. GC-MS results showed that 148 flavor compounds were identified in rose white tea, with linalool, citronellol, geraniol, phenylethanol, citral, phenylacetate, and methyl eugenol identified as the main contributors to the aroma characteristics of rose white tea. Citronellyl acetate and 2-undecanone were characteristic aroma compounds during the rose withering stages (WT0-WT48). The concentrations of citronellyl acetate exhibited an initial increase followed by a subsequent decline (WT0: 2.347mg/kg; WT12: 2.455mg/kg; WT24: 3.646mg/kg; WT36: 3.176mg/kg; WT48: 1.217mg/kg;). Phenylacetaldehyde and cyclotridecanone were unique aroma compounds found in dried rose white tea (HAD).

The inherent hydrophilicity of cotton fabrics (CFs) limits their application in advanced functional textiles. Superhydrophobic surface modification has emerged as an effective strategy to impart functionalities such as self-cleaning and oil-water separation. Here, a two-step surface modification approach—combining graft condensation with free radical copolymerization—is developed to fabricate superhydrophobic CFs. The resulting fabrics exhibit a high water contact angle of 163° and a low sliding angle of 7°, indicating excellent surface hydrophobicity. The hydrophobic layer demonstrates exceptional mechanical robustness and chemical stability, maintaining a contact angle above 144° after 150 abrasion and 30 washing cycles. Furthermore, the hydrophobicity remains stable (contact angle >150°) under harsh conditions, including exposure to organic solvents, UV irradiation, elevated temperatures, and acidic/alkaline environments. The modified CFs also exhibit excellent self-cleaning performance and maintain oil-water separation efficiency exceeding 98 % after 20 cycles. These results highlight the potential of the developed modified CFs for applications in outdoor gear, anti-fouling textiles, and marine oil spill remediation.

Direction recognition capability is essential for intelligent systems to interact with the physical environment. However, current sensor systems often suffer from poor stability and response delays due to their complex circuit designs or multi-signal fusion algorithms. Inspired by the trichobothria on the tarsi of water striders, this study develops a bioinspired single-circuit multidirectional sensor (BSMS). By introducing an asymmetric mechanical structure with 20° directional tilt and 1/2-radius radial eccentricity, the design overcomes the axisymmetric limitations of conventional cantilever beams. By integrating a “wire-dot” heterodimensional composite conductive system, this approach achieves the resolution of multidirectional mechanical stimuli within a single sensing unit. The BSMS features an ingenious physical architecture that enables directional recognition using only a simple output circuit. The BSMS eliminates the need for multi-signal fusion algorithms while demonstrating outstanding overall performance. Its four-directional output signals exhibit 50% discrimination, along with excellent sensitivity across a wide range of 73.79–226.77 N −1 . Moreover, the BSMS shows ultra-high response consistency (>98%) and rapid dynamic response (277.35%/s response rate and 89.47%/s recovery rate). Additionally, its stability is confirmed through 100-cycle testing. Inspired by the remarkable aquatic adaptability of water striders, we applied the BSMS to obstacle detection and directional recognition for remotely operated vessels. When integrated with deep learning algorithms, the BSMS achieved over 99% accuracy in both texture identification and directional sensing. This system offers a promising solution for autonomous obstacle avoidance, precision cargo delivery, and multi-vessel coordination in complex aquatic environments. It demonstrates potential for broader applications in flexible electronics and intelligent systems.

Rationally designed electrocatalysts with excellent catalytic activity and robust stability are essential for enhancing the performance of water splitting toward a near-future hydrogen economy. In this work, we report a highly efficient triphase hetero-interface heterostructured electrocatalyst consisting of ultrafine Rh nanoparticles anchored on Cu3P/MnP nanosheets supported on Ni foam (labelled Rh/Cu3P/MnP) to boost the performance of overall water splitting. Experiments clarify the impressive role of the triphase hetero-interface of Rh, Cu3P, and MnP in interfacial electronic redistribution, which is significant for optimizing the catalyst's ability to adsorb and desorb reaction intermediates, thereby accelerating electrochemical reaction kinetics. Additionally, the rationally controlled multi-dimensional structure-comprising 0D Rh nanoparticles, 2D Cu3P/MnP nanosheets, and a 3D Ni substrate-endows the catalyst with a large electrochemically active surface area, excellent charge transfer ability, and abundant accessible active species. Therefore, the Rh/Cu3P/MnP catalyst demonstrates promising catalytic performance for the two key reactions in water splitting: the hydrogen evolution reaction and the oxygen evolution reaction. Moreover, a water electrolyzer utilizing Rh/Cu3P/MnP catalytic electrodes exhibits remarkable efficiency and remains stable over 50 h of continuous operation.

The fabrication of eco-friendly bio-based epoxy resins is of critical importance for addressing the excessive consumption of petroleum resources and the release of harmful substances caused by petroleum-based thermosetting epoxy resins. However, the non-recyclability and poor mechanical properties of bio-based epoxy resins hinder their further development and application. Herein, a strong, tough, recyclable, and multifunctional bio-based epoxy vitrimer is prepared using epoxidized soybean oil (ESO) and lignin-based aromatic monomers of vanillyl alcohol, guaiacol, and vanillin. These lignin-based aromatic monomers provide bio-based aromatic building blocks for the synthesis of bisguaiacol F diamine vanillin (BGAV) with dynamic imine bonds, which is employed as a curing agent for ESO to fabricate a bio-based epoxy vitrimer incorporating a dynamic network. The BGAV forms rigid polyaromatic segments in the network to enhance the stability of the polymer, thereby leading to a high mechanical strength of 21.81 MPa for the epoxy vitrimer. Moreover, the hydrogen bonds in the network serve as sacrificial bonds to increase the ability of energy dissipation, thereby resulting in excellent toughness of 27.53 MJ m−3 for the epoxy vitrimer. Additionally, the reversible reconstruction of dynamic imine bonds within the network endows the vitrimer with favorable self-healing properties and recyclability. Furthermore, the vitrimer also exhibits outstanding antibacterial properties, mold resistance, photothermal conversion performance, water resistance, and bonding performance. This work provides an effective approach for the development of recyclable bio-based epoxy resins with exceptional mechanical properties and multifunctionality.

Multi-stimulus responsive materials have attracted significant attention due to their ability to respond dynamically to multiple external stimuli, including light, temperature, and chemical signals. Achieving both rapid response times and precise selectivity is essential for advancing the functionality of such materials. In this study, five polyoxometalate-based viologen ionic liquids (ILs) were synthesized through ion exchange between H3PMo12O40 and viologen ILs with varying substituents. These ILs demonstrated multi-stimulus responses to light and ammonia gas. Under Xe lamp irradiation, all ILs exhibited prominent photochromism, with C12–PMo12 undergoing a rapid change from light yellow to light green within just 5 seconds. Exposure to an H2O2 atmosphere for 3 hours resulted in the complete decolorization of C12–PMo12. Remarkably, after five cycles of coloring and decoloring, its absorbance remained virtually unchanged, highlighting its excellent reversibility and stability. Additionally, as the alkyl chain length of the viologen-based cation increased, the coloring rate accelerated, and the color contrast enhanced, likely due to the suppression of viologen radical quenching by longer carbon chains. These ILs also exhibited gas-chromic behavior in the presence of ammonia, showing high detection selectivity. Furthermore, the materials were successfully applied in inkless erasable printing and ultraviolet detection. The C12–PMo12-based carbon paper displayed clear and readable prints in only 10 seconds and could be bleached in an H2O2 atmosphere within 1.5 hours. These findings demonstrate that the synthesized ILs possess versatile multi-stimulus responsive properties, making them highly promising for applications in inkless printing, ultraviolet detection, and amine vapor sensing.

Here, the Bi 24 O 31 Br 10 -based composite photocatalysts modified by bimetallic Bi and Mo nanoparticles (NPs) are designed and prepared (Bi-Mo-Bi 24 O 31 Br 10 ). 2D ultra-thin Bi 24 O 31 Br 10 nanosheets with suitable band gap and good chemical and optical stability are selected as the main catalyst to drive N 2 fixation by generating hot carriers. The Bi NPs in the Bi 24 O 31 Br 10 nanosheets serves as a buffer tank for electrons to improve the efficiency of electron transfer. Meanwhile, the Mo NPs serve as catalytic centers for N 2 adsorption and activation, working synergistically to enhance the overall reaction efficiency. Resulting from semiconductor-to-metal −to-metal electron transfer path and the Mo metal adsorption and activation mechanism, the nitrogen fixation rate of the Bi-Mo-Bi 24 O 31 Br 10 photocatalyst is as high as 191.2 μmol g −1 h −1 , and it is 7.2 times compared to pure Bi 24 O 31 Br 10 . This work creates a novel framework for the rational design of highly efficient visible-light-responsive nitrogen fixation catalysts.

Nasopharyngeal carcinoma (NPC) is mostly found in Southeast Asia and Southern China and is highly aggressive and metastatic. It is well known that radiotherapy is the main therapeutic method for NPC; however, the existence of radiotherapy resistance seriously affects treatment efficacy and leads to poor outcomes. Currently, there is still a lack of effective methods for the prediction of radiotherapy resistance. MicroRNA (miRNA), as a biomarker widely involved in the processes of cell proliferation, differentiation and apoptosis, is a key driver of cancer development and progression. In this study, a SERS-based biosensor was designed for the specific detection of NPC-associated miRNA (miRNA-324-3p) by embedding Raman reporter molecules into gold‑silver core-shell nanoparticles, achieving the limit of detection of 8.41 pM. The advantages of this method such as ease of operation, rapidity, and non-invasive manner, make it a promising method for the detection of NPC radiotherapy resistance.

Studies on highly efficient heterojunction photocatalysts are regarded as an important task for H 2 production by water splitting. In this work, a novel ternary Fe 3 S 4 /ZnCdS/ZnS (FS/ZCS/ZnS) heterostructures were successfully prepared by a simple grinding method. With ZCS/ZnS nanoclusters loading on the surface of Fe 3 S 4 microflowers, photocatalytic H 2 production of ZCS/ZnS was largely improved in lactic acid (LA) solution. The H 2 evolution rate of FS/ZCS/ZnS is high up to 4.36 mmol g −1 h −1 under visible light irradiation and 8.13 mmol g −1 h −1 under full spectrum irradiation. Prolonged experiments and cycle tests showed that FS/ZCS/ZnS is stable and reusable. The formation of ternary heterostructures facilitates the separation and transfer of photogenerated charge carriers (PCCs, including photogenerated electrons and holes), leading to the activity enhancement of photocatalytic H 2 production. The strategy for the heterojunction construction can provide more perspective for the design of high-efficiency and recyclable photocatalysts for H 2 evolution.

Microporous hyper-cross-linked polymers appending variant electron-withdrawing functional groups have enormous potential for selective CO 2 adsorption and separation, whereas these functionalities by lowering the charge density of monomers will decrease their reaction activity, which in turn is unfriendly for the direct and highly efficient preparation of polymers with high CO 2 uptake capacity. Herein a new amide “insertion” strategy for knitting polymers with ideal electron-withdrawing functionalities was advanced, and in this manner, a series of carboxyl enriched novel polymers were synthesized via the one-pot Friedel-Crafts alkylation reaction by using fluorene derivatives as emerging building blocks. The created polymer 3 possessing BET surface area 1947 m 2 g −1 have a CO 2 uptake of up to 20.03 wt% at 273.15 K/1.00 bar. Besides, the carboxyl and amide groups in structure could bestow the polymers an enhanced CO 2 /N 2 selectivity of 33.17 at 273.15 K. In addition, the hierarchical porosity and CO 2 adsorption capability of manufactured polymers can be intriguingly tailored, and prolonging the carboxylated side chains of building blocks by inserting different quantities of amide group will be propitious for bettering the porosity and CO 2 capturing capacity of manufactured polymers. Supported by charge density distribution simulation and electrostatic potential calculation, the peculiar changes in polymer structures and CO 2 adsorption features were also explained.
