High-voltage sodium metal batteries (SMBs) present a viable pathway towards high-energy-density sodium-based batteries due to the competitive cost advantage and abundant supply of sodium resources. However, they still suffer from severe capacity decay induced by the notorious decomposition of the electrolyte under high voltage and unstable cathode/electrolyte interphase (CEI). In addition, the high reactivity of Na metal and flammable electrolytes push SMBs to their safety limits. Herein, a special dual-anion aggregated Na + solvation structure is designed in a nonflammable trimethyl phosphate-based localized high-concentration electrolyte, and a gradient CEI enriched with phosphorus and boron compounds is formed on the cathode. This thin and stable interphase effectively suppresses the parasitic reaction, improves the interfacial stability of the cathode, and facilitates Na + transport through the interface by the synergistic effect of multi-components, thus optimizing the cycling stability and safety of SMBs. The Na 0.95 Ni 0.4 Fe 0.15 Mn 0.3 Ti 0.15 O 2 //Na batteries employing such electrolyte provide a discharge capacity of 167.5 mAh g −1 and high retention in the capacity of 85.2 % after 800 cycles at 1 C. This approach offers a general strategy for the design of flame-retardant high-voltage electrolytes and the practical application of SMBs.

The stability of the electrode-electrolyte interface is crucial for the long-term operation of battery chemistries, particularly under harsh conditions with corrosive acidic/alkaline aqueous electrolytes. Here, we report the design of a H₂¹⁸O-H₂¹⁶O isotope interface to promote the formation of a protective electrode-electrolyte interphase, as demonstrated by a model investigation based on an aqueous proton battery (APB) utilizing strongly acidic aqueous electrolytes. This design enables the manganese-iron Prussian blue analog (MnFe-PBA), typically considered acid intolerant, to cycle stably over 10,000 cycles in corrosive H₃PO₄ electrolytes. This acid resistance is attributed to the isotope interface-governed in situ formation of interphases comprising hydrogen-bonded frameworks. With the high-energy MnFe-PBA cathode, the full battery attains a high voltage plateau (⁓1.2 V) and energy density (77.6 Wh kg⁻¹), both surpassing all previously reported APBs. Our findings provide a novel approach for enhancing the performance of aqueous batteries subject to extremely corrosive conditions and encourage the integration of isotopic science with battery technology. © 2025 Elsevier Inc.

With the rapid development of industries, the heavy metal-containing wastewater has become one of the most serious environmental problems. Adsorption is a key approach in treating heavy metal-containing wastewater. The performance of adsorbents is determined by the effective exposure of its adsorptive sites, which determines its adsorption capacity . In this study, fibrous chitosan/cellulose composite was prepared using the wet-spinning method to increase its specific surface area, thus enhancing the adsorption capacity. The as-prepared fibrous composite showed a homogeneous fiber structure (diameter: 88 ± 16 μm) and high specific surface area (2.5 m 2 g −1 ). Furthermore, the adsorption capacity towards Co(Ⅱ) was greatly enhanced, more than three times higher than that of the pure chitosan beads (diameter: 2–3 mm). The maximum adsorption capacity was calculated to be 23.6 ± 2.5 mg-Co(Ⅱ) per g-chitosan by the Langmuir isotherm model, an order of magnitude higher than that of pure chitosan beads. In addition, the adsorption kinetic behavior of chitosan/cellulose fibers on Co(Ⅱ) followed the pseudo second-order kinetic model . The optimal pH for Co(Ⅱ) removal was approximately 6.0. Furthermore, FT-IR and XPS analyses indicated the amino groups played a dominant role, with the aid of hydroxyl groups, in the coordination and adsorptive removal of Co(II). Possible interaction configurations were also proposed in this study. In conclusion, the proposed physical modification of chitosan greatly improved its adsorption capacity and mechanical strength, making it a promising biosorbent for Co(II) removal.

Electrochemical urea oxidation reaction (UOR) offers a promising alternative to the oxygen evolution reaction (OER) in clean energy conversion and storage systems. Nickel-based catalysts are regarded as highly promising electrocatalysts for the UOR. However, their effectiveness is significantly hindered by the unavoidable self-oxidation reaction of nickel species during UOR. To address this challenge, we proposed an interface chemistry modulation strategy to boost UOR kinetics by creating a high-energy interfacial heterostructure. This heterostructure incorporates Ag at the CoOOH@NiOOH heterojunction interface, where strong interactions significantly promote the electron exchanges at the heterojunction interface between -OH and -O groups. Consequently, the improved electron delocalization leads to the formation of stronger bonds between Co sites and urea CO(NH 2 ) 2 , promoting a preference for urea to occupy Co active sites over OH*. The resulting catalyst, Ag−CoOOH@NiOOH, demonstrates ultrahigh UOR activity with a low potential of 1.33 V at 100 mA cm −2 . The fabricated catalyst exhibits a mass activity over 11.9 times greater than the initial cobalt oxyhydroxide. The rechargeable urea-assisted zinc-air batteries (ZABs) achieve a record-breaking energy efficiency of 74.56 % at 1 mA cm −2 , remarkable durability (1000 hours at a current density of 50 mA cm −2 ), and quick charge performances.

Bismuth-based materials have been recognized as promising catalysts for the electrocatalytic CO 2 reduction reaction (ECO 2 RR). However, they show poor selectivity due to competing hydrogen evolution reaction (HER). In this study, we have developed an edge defect modulation strategy for Bi by coordinating the edge defects of bismuth (Bi) with sulfur, to promote ECO 2 RR selectivity and inhibit the competing HER. The prepared catalysts demonstrate excellent product selectivity, with a high HCOO − Faraday efficiency of ≈95 % and an HCOO − partial current of ≈250 mA cm −2 under alkaline electrolytes. Density function theory calculations reveal that sulfur tends to bind to the Bi edge defects, reducing the coordination-unsaturated Bi sites (*H adsorption sites), and regulating the charge states of neighboring Bi sites to improve *OCHO adsorption. This work deepens our understanding of ECO 2 RR mechanism on bismuth-based catalysts, guiding for the design of advanced ECO 2 RR catalysts.

In this study, a novel fibrous chitosan biosorbent was prepared using LiOH/KOH/urea/HO (4.5:7:8:80.5 by weight) as spinning solvent. The fibrous chitosan exhibited a higher adsorption capacity and a faster adsorption rate for Co and Sr, compared with spherical chitosan due to its high specific surface area (16.9 m g), uniform fineness (24.1 μm), and good mechanical strength. The adsorption capacity of fibrous chitosan for Co and Sr was 31.3 mg g and 20.0 mg g, respectively, which was higher than that of spherical chitosan (22.5 mg gfor Co and 8.9 mg g for Sr). The coordination between -NH/-OH of chitosan and the nuclide ions was the rate-limiting step. The improvement of adsorption performance was due to the higher specific surface area which increased the exposure degree of functional groups (adsorptive sites). This new wet-spun fibrous chitosan biosorbent showed great potential in the adsorptive removal of nuclides ions from aqueous solution.

A highly efficient on-chip acousto-optic modulator, as a key component, occupies an exceptional position in microwave-to-optical conversion. Homogeneous thin-film lithium niobate is preferentially employed to build the suspended configuration forming the acoustic resonant cavity to improve the modulation efficiency of the device. However, the limited cavity length and complex fabrication recipe of the suspended prototype restrain further breakthrough in the ME and impose challenges for waveguide fabrication. In this work, based on a nonsuspended thin-film lithium niobate-chalcogenide glass hybrid Mach–Zehnder interferometer waveguide platform, we propose and demonstrate a built-in push-pull acousto-optic modulator with a half-wave-voltage-length product VπL as low as 0.03 V cm, presenting a modulation efficiency comparable to that of the state-of-the-art suspended counterpart. Based on the advantage of low power consumption, a microwave modulation link is demonstrated using our developed built-in push-pull acousto-optic modulator. The nontrivial acousto-optic modulation performance benefits from the superior photoelastic property of the chalcogenide membrane and the completely bidirectional participation of the antisymmetric Rayleigh surface acoustic wave mode excited by the impedance-matched interdigital transducer, overcoming the issue of amplitude differences of surface acoustic waves applied to the Mach–Zehnder interferometer two arms in traditional push-pull acousto-optic modulators.

Realizing high energy-density and actual applications of fibre-based electrochemical supercapacitors (FESCs) are pivotal but challenging, as the ability to construct advanced fibres for accelerating charges kinetic diffusion and Faradaic storage remain key bottlenecks. Here, we demonstrate high-performance FESCs based on hetero-structured polymetallic oxides/porous graphene core–sheath fibres, where the large pseudo-active polymetallic oxide (PMO) sheath is uniformly loaded on a hierarchical porous graphene fibre (PGF) core. Due to the abundant micro-/mesoporous pathways, large accessible surface, excellent redox activity and good interface electron conduction, the PMO-PGF possesses high areal capacitance (2959.78 mF cm −2 ) and manageable Faradaic reversibility in a 6 M KOH electrolyte. Furthermore, the PMO-PGF-based solid-state FESCs present high energy-density (187.22 μ Wh cm −2 ), long-life cycles (95.8 % capacitive retention after 20 000 cycles), diverse-powered capabilities and actual energy-supply applications.

Journal of Physics: Conference Series 2021年第1期2101卷

作者： Ming Xiao Xiaojiang Sun Huaqing Rong Shuguang Bi Jiagong Tang Xianmeng Luo Jianhua Ran Hubei Key Laboratory of Biomass Fibers and Eco-Dyeing & Finishing State Key Laboratory of New Textile Materials and Advanced Processing Technologies College of Chemistry and Chemical Engineering Wuhan Textile University Wuhan 430200 China Hubei DaTangAnSheng Construction Engineering Co.

Epoxy structural adhesive has good mechanical properties, especially high adhesion, low shrinkage rate, and high stability, widely used in steel plate reinforcement, crack repair, bridge splicing, and concrete bonding, etc. However, due to the high cross-linking density and high internal stress after curing, its shortcomings, such as brittleness, the poor performance of fatigue resistance and heat resistance, limit its application in special track engineering. In this work, two kinds of epoxy structural adhesives (EPA-1, EPA-2) with low viscosity and room temperature curing were synthesized by selecting different bisphenol A epoxy resin and active diluent as component A and modified amine curing agent as component B. The results showed that EPA-1 and EPA-2 presented significant toughness compared with the classic construction adhesive (AralditeXH160). The yield strengths of EPA-1 and EPA-2 were 4.88 MPa and 13.13 MPa, and the shear strengths were 11.93 MPa and 13.08 MPa, respectively, showing good adhesive properties. In addition, the viscosities of EPA-1 and EPA-2 were 127 mPa·s and 308 mPa·s, respectively, and their decomposition temperatures were all above ∼280 °C, which indicated that the self-made epoxy structural adhesives could be used for the repair of cracks in the vibration subway tunnel.
