... [6][7][8][9][10][11] While significant advancements have been made in improving EMW absorption performance, the effective application of these materials under extreme temperature conditions remains a major challenge, necessitating further improvements in their overall properties. [12,13] Electromagnetic protection under extreme temperature conditions requires materials with superior thermal insulation properties and mechanical robustness to endure severe temperature fluctuations and complex external stresses. [13][14][15] To meet the requirements for electromagnetic and thermal protection in extreme environments, extensive research has been conducted. ...

... The thermal protective performance of firefighting clothing primarily relies on thermal barrier layer in the multilayered fabric system, which can effectively protect firefighters from environmental thermal hazards during high heat exposure. Aerogels exhibit exceptional low density and thermal insulation performance, positioning them as the most promising candidates for highefficiency thermal protection in firefighting clothing [1][2][3][4][5][6]. Among them, aramid nanofibers (ANFs)-based aerogel is the preferred choice for thermal barriers in firefighting clothing due to its superior thermostability and pore structure at the nano-and microscales, which significantly suppresses thermal conduction and convection within the aerogel skeleton under high radiant heat exposure [7][8][9][10]. ...

... However, similar to most oxide insulation materials, the thermal conductivity of mullite nanofiber aerogel exhibits a substantial increase with rising temperatures, which considerably restricts its applicability in high-temperature environments. The incorporation of infrared shielding agents, such as SiC [22], carbon (C) [23], and titanium dioxide (TiO 2 ) [24], into insulation materials serves as an effective strategy to mitigate the pronounced rise in thermal conductivity of oxide insulation materials under elevated thermal conditions. Zhang et al. [25] developed a mullite/ TiO 2 composite fiber aerogel that exhibits significant hightemperature infrared shielding properties. ...

... Furthermore, the oxidation and corrosion behavior of SiC f /SiC/AIN composite were investigated by Sun et al. 92 in dry oxygen and water oxygen atmospheres at 1100-1300 • C to examine the microstructure evolution on the formed oxide layer. Self-healing behaviors under high temperatures, crack-healing ability enhancement, strength recovery rate, and material design strategy are analyzed considering several composites in the last 3 years, which are summarized. ...

... Furthermore, the magnetism of GBS 2 and GBS 4 with in situ-grown BN are superior to those of GS 2 . This is due to the fact that the introduction of BN encapsulates the Fe 3 O 4 particles, thereby reducing their transition to the FeSi process [37]. Additionally, BN produces an induced magnetic moment in a magnetic field and exhibits weaker para magnetism [38]. ...

... However, the mismatch between the thermal expansion coefficient and thermal stability of the toughening phase and the ceramic matrix will lead to holes and defects inside the composites, resulting in a decrease in the mechanical properties of the composite material. [8,16,17] (3) The interfacial bonding effect between the toughening phase and the ceramic is still unclear but very important. The interfacial region in CMCs is defined as the critical transition zone, where a gradient variation in chemical composition occurs between the toughening phase and the matrix phase. ...

... While the discovery of the BPVE originated from research on ferroelectric perovskite oxides (10) (11) (12) (13) (14) (15) (16) (17), these materials have not been considered a viable solution against traditional solar cell technology due to their low light-to-electrical power conversion efficiency. Alternatively, van der Waals (vdW) materials present straightforward strategies for breaking inversion symmetry, offering a new and exciting avenue for BPVE research (18) (19) (20) (21) (22) (23) (24) (25) (26) (27) (28). Especially, vdW polar materials have demonstrated large responsivities on the order of 1-10 mA/W when implemented in vertical device architectures (29) (30) (31) (32) (33). ...

... [1][2][3][4][5][6] Compared to conventional micron-sized fibers, single-crystal SiC nanowires (SiC nw ) have garnered considerable interest because of their remarkable elastic modulus (Young's modulus ranging from 610 to 660 GPa) and high bending strength (with a maximum bending strength of 53.4 GPa for a single SiC nanowire), 7,8 resulting in substantial reinforcement effects in CMCs. [9][10][11][12] Given the exceptional properties of SiC nanowires, there has been a growing focus on the development of SiC nanowire-reinforced CMCs. Several approaches have been proposed for the in situ growth of SiC nanowires on fiber surfaces or within the pores of ceramics, leading to the formation of SiC nanowires reinforced CMCs. ...
