advanced aerogel fibers possess numerousadvantages amalgamating the attributes of aerogels and fibermaterials, rendering them invaluable in the realm of thermalmanagement and regulation. However, the achievement ofrobust mechanical properties and increased temperaturestability is still a major challenge for the majority of aerogelfibers. Herein, SiO_(2)-Kevlar hybrid aerogel fibers with bioniccore-shell structure were prepared by reaction spinning andweaved into fabric. Kevlar nanowires dispersion is pumpedinto a bath comprising a self-synthesized silica sol, whichfacilitates the hybridization of biphasic aerogels through thegel reaction. Precise control over the diameter (200-800 μm)and structure of the wet gel fibers was achieved throughmeticulous adjustment of the spinning solution composition and spinning parameters. Subsequent freeze-drying processfacilitates the formation of a core-shell hybrid structure, in which the SiO_(2) aerogel layer effectively encapsulate the Kevlaraerogel core fiber. Taking full advantage of the mechanical properties of the Kevlar core fiber, the resulting SiO_(2)-Kevlaraerogel fibers exhibit commendable weaving characteristics (51.8 MPa). Furthermore, SiO_(2)-Kevlar aerogel fabrics exhibitenhanced thermal insulation characteristics with a thermal conductivity of 0.037 W/(m·K). As a result of the presence ofexternal SiO_(2) aerogel layer, the overall temperature resistance performance of the SiO_(2)-Kevlar fabric reach up to 700 ℃.

Electronics over flexible substrates offer advantages of flexibility, portability and low cost, and promising applications in the areas of energy, information, defense science and medical service. In recent years, tremendous progress has been witnessed in the development of flexible wearable devices that can be potentially massively deployed. Of particular interest are intelligent wearable devices, such as sensors and storage cells, which can be integrated by flexible magnetoelectronic devices based on magnetic thin films. To examine this further, the magnetic properties of FeNi thin films with different thicknesses grown on flexible graphene substrate are investigated at room temperature. The coercivity increases with increasing thicknesses of FeNi thin film, which can be attributed to the increase of grain size and decrease of surface roughness. Moreover, the thickness modulated magnetic property shows a magnetic anisotropy shift increase with varying thicknesses of FeNi thin film by using measurements based on ferromagnetic resonance, which further enhances the resonance frequency. In addition, the resonance peak is quite stable after bending it for ten cycles. The result is promising for the future design of flexible magnetoelectronic devices.

With the sustainable and efficient development of aqueous zinc ion batteries (AZIBs), the research on addressing the issues of the adaptability and durability of zinc anodes has been hot-topic and is still of great challenge. In this work, inspired by the sand treatment and afforestation of the Gobi Beach in Northwest China to ameliorate the problem of wind and sand encroachment, we propose a material with a morphology similar to that of a "shelter forest", CuSiO3 nanoneedles arrays grown on both sides of reduced graphene oxide (rGO@CuSi), as a coating layer on the zinc metal surface to guide Zn gradient deposition. The presence of rGO improves the electrical conductivity of CuSiO3, and the finite element simulation of the electric field and Zn2+ concentration proves that the electric field distribution can be effectively homogenized and the local current density can be reduced for the rGO@CuSi-Zn electrode with the surface presenting the shape of a protective forest. This is due to the abundant pores between the nano-needle array structures on the surface of the electrode, which provide high electron and ion transport paths, and are conducive to achieving uniform Zn deposition, like the principle of wind-sand stabilization by protective forest. Both electrochemical experiments and density functional theory calculations show that the negatively charged surface of rGO@CuSi with good Zn affinity is more capable of guiding Zn2+ transport. Thanks to its inherent material and structural characteristics, the rGO@CuSi-Zn anode has a high specific capacity and good cycling stability. This study provides insight for interface engineering like protective forest to accelerate the commercialization of high-performance Zn-based batteries. © 2024 Institute of Process Engineering, Chinese Academy of Sciences
