Aqueous zinc batteries offer significant potential for large-scale energy storage, wearable devices, and medium-to low-speed transportation due to their safety, affordability, and environmental friendliness. However, the uneven zinc deposition at the anode side caused by localized reaction activity from the passivation layer presents challenges that significantly impact the battery's stability and lifespan. In this study, we have proposed an expandable and maneuverable gel sustained-release (GSR) treatment to polish the Zn metal, which in situ converts its native passivation layer into a composite interphase layer with nanocrystal zinc phosphate and flexible polyvinyl alcohol. Such a thin and uniform interface contributes to fast and homogeneous Zn ion transport and improved anti-corrosion ability, enabling uniform zinc deposition without dendrite growth and thereby improving the battery performance with high-rate ability and long cycle life. This GSR treatment method, characterized by its simplicity, low cost, and universality, facilitates the widespread application of aqueous zinc batteries. © 2025 Institute of Process Engineering, Chinese Academy of Sciences

Magnolol a Chinese medicinal herb that has been used for treating cough, phlegm and inflammation for a thousand years. Appreciating its low absorption rate that limits its use, there is need to develop porous magnolol foams that are light weight, low density, portable while maintaining tissue integrity to expand its application. This study proposes an innovative method for creating a biocompatible foam through a one-pot process involving reacting magnolol with sulfhydryl compounds, utilizing a thiol-ene click reaction to create a foam. Various foams were systematically formulated by adjusting the degrees of cross-linking, concentrations of the foaming agent 2,2'-azobis(2-methylpropionitrile) (AIBN), and the temperature and pressure conditions during the foaming. AIBN acted both as a blowing agent and initiator, triggering cross-linking in the polymer solution by releasing free radicals and nitrogen gas. This initiated rapid expansion when a critical viscosity threshold was reached, ultimately curing the foam. The optimal foaming efficiency was achieved when the molar ratio of allyl to mercapto groups was maintained at 1:1, pentaerythritol tetrakis(3-mercapto-propionate) (PETMP) identified as the optimal sulfhydryl compound. Increasing the dosage of AIBN enhanced gas generation, further expanding foam volume, pore size and porosity, the foam is lightest when the amount of AIBN is 7.5%. When magnolol-based foams were prepared under sealed conditions at 100°C, without external pressure, they exhibited large, uniformly distributed pores and excellent water-absorbing properties. Moreover, the resulting foams demonstrated remarkable thermal stability and resilience. These findings offer a new design strategy for engineering high-performance functional magnolol foams with high biomass content. © 2025, The Authors. All rights reserved.

Transition metal silicates (TMSs) are frequently utilized as supercapacitor electrode materials because of their great thermal stability, plentiful reserves, and controlled structure. However, improving the conductivity of silicate materials is still the research goal. In order to create an effective carbon composite strategy, the sandwich structure of TMSs/carbon materials/TMSs is built in this article. Additionally, the Al element is included to enhance the electrochemical performance of silicate materials. This study describes the preparation of an aluminum-doped cobalt silicate/reduced graphene oxide/aluminum-doped cobalt silicate sandwich-like structure (Al-doped Co2SiO4/rGO/Al-doped Co2SiO4, denoted as rGO/ACS), applying a straightforward hydrothermal process with aluminum-doped silica/GO/aluminum-doped silica (Al-doped SiO2/GO/Al-doped SiO2, denoted as GO/Al-SiO2) as the template. At 1 A g−1, the specific capacity of rGO/ACS can reach 573 F g−1, which is 10 times that of CS (Co2SiO4, 57 F g−1) and 1.6 times that of rGO/CS (Co2SiO4/rGO/Co2SiO4, 362 F g−1). After 10,000 cycles, the capacitance retention of rGO/ACS is still 91 %, whose electrochemical performance is far superior to other silicon-based materials. In addition to having a surface capacitance of 763 mF cm−2 at 1 mA cm−2 with 81 % cycle performance after 8000 cycles, the rGO/ACS//AC hybrid supercapacitor performs exceptionally well electrochemically. This work demonstrates how the creation of Al-introduced TMSs/carbon materials/Al-introduced TMSs sandwich structure enhances the performance of silicate materials by combining the benefits of carbon composite and metal introduction, and it offers an option to further boost the conductivity of silicate. © 2025 Elsevier B.V.

Thermal sensing materials capable of monitoring critical fire risks of combustible materials with a rapid response show great potential in early fire warning. However, the thermoelectric materials used in current fire-warning systems usually have low mechanical strength and poor flexibility, limiting their application in harsh environments and in wearable devices. In this work, a class of multilaminated MXene/aramid nanofiber (ANF)/poly(ethylene glycol) (PEG) composite film (MAP) was developed by a vacuum-induced self-assembly method. Because of the compatibility of the hybrid building units with reinforced interconnections, the MAP films exhibit excellent mechanical properties in terms of tensile strength (139.9 MPa), toughness (20.7 MJ/m³), strain (23.1%), modulus (6.1 GPa), and durability (fold times: 39,991). Moreover, the MAP films showed superior fire retardancy with the LOI value of 35%, exhibiting rapid self-extinguishing capability. Significantly, taking advantage of the thermoelectric effect and continuous conductive paths of MXene nanosheets, rapid cyclic contact/noncontact fire warning (<1 s) was achieved. Integrating the MAP film into the IoT system enabled remote real-time fire monitoring and feedback with a rapid response. In addition, the MAP film can be employed as an early fire-warning coating on textiles, further expanding its wearable fire alarm scope. This work provides a perspective for designing robust wearable early fire detection sensors and fire protection applications. © 2025 American Chemical Society.

Recycling cellulose-based waste textiles (CBWT) into high-performance functional materials is a key challenge in sustainable green development strategies. Herein, a combination of water bath wet spinning and gradient solvent exchange methods is employed to develop a regenerated cellulose aerogel fiber (CAF) with excellent mechanical and thermal insulation properties. CAF fibers, with a core-shell structure, exhibited an excellent mechanical property, with a tensile strength of 16.56 ± 1.48 MPa, a strain at break of 67.9% ± 10.37%, and toughness of 6.65 MJ m−3 in the absence of draft process. Furthermore, the CAF fabrics demonstrated outstanding thermal insulation performance (39.31 mW/m/K), with a temperature difference of 45 °C at 100 °C, significantly reducing heat transfer compared to conventional materials, exhibiting a great promise for use in heat-resistant and cold-weather clothing. Most importantly, the process of CBWT dissolution is significantly accelerated by preheating the ionic liquid (IL)/DMSO solution system, which will significantly improve the recycling efficiency and economic benefits of CBWT. This study provides a simple and effective method for fabricating a high-performance regenerated cellulose aerogel fiber, aiming to promote the development of the textile recycling industry and the innovation of sustainable functional materials. © 2025 Wiley-VCH GmbH.

With global freshwater scarcity and increasing water pollution due to industrial and agricultural activities, there is an urgent need for sustainable, high-performance water treatment materials. Conventional filtration and adsorption materials, such as polymer membranes and activated carbon, often suffer from high energy consumption, secondary pollution, and high production costs. In contrast, wood-based materials offer hierarchical porosity, natural adsorption sites, and tunable surface chemistry, making them a promising candidate for low-cost and environmentally friendly water treatment applications. In this review, we introduced the structure and properties of wood and described how these affect the preparation and water treatment properties of wood-based materials. We also summarized the structure design strategies for wood-based materials, mainly including delignification treatment, nanomaterials modification, functional group modification, and carbonation modification. In addition, we presented a comprehensive investigation of advances in the application of wood-based materials in water treatment with the aim of comparing, analyzing, and evaluating the practical functionality in sterilization, heavy metal ion removal, organic pollutants removal, oil/water separation, and desalination. Finally, we presented the serious challenges and new perspectives for wood-based materials in water treatment. © 2025 Elsevier Ltd

Iron-doped Nano-hydroxyapatite: Preparation and Ultraviolet Absorption Performance

引用

Wuji Cailiao Xuebao/Journal of Inorganic materials 2025年第5期40卷 457-465页

Nano-hydroxyapatite (nHAP) possesses both biocompatibility and environmental friendliness, and holds the potential to become a novel ultraviolet (UV) absorbent material following iron doping modification. This study employed co-precipitation and hydrothermal methods to prepare iron-doped nano-hydroxyapatite (Fe-nHAP). Influence of the preparation process on UV absorption performance was investigated by adjusting reaction time, temperature, and iron doping ratio. The results indicate that with the increase of temperature from 37 ℃ to 150 ℃ or the extension of reaction time from 0.5 h to 3 h, both the crystallinity and the peak of UV absorption improve. It can be inferred that there is a certain positive correlation between the UV absorption performance and crystallinity of Fe-nHAP. Additionally, the UV absorption capacity is closely correlated to the iron doping ratio. As the iron doping molar ratio increases from 0 to 10%, the UV absorption capacity is gradually enhanced, with the maximum absorption value rising from 0.03 to 1.35. This phenomenon is attributed to the reduction in optical bandgap caused by iron doping. However, a high iron doping ratio leads to excessive reduction in material crystallinity, resulting in weakened enhancement of UV absorption performance. The safety assessment indicates that Fe-nHAP with an iron doping molar ratio of 7% does not demonstrate cytotoxicity, phototoxicity and skin irritation. In summary, Fe-nHAP has a suitable UV absorption performance. With its favorable biosecurity, it is anticipated to emerge as a new type of UV absorption material. © 2025 Science Press.
