Ceramic aerogels are highly efficient, lightweight, and chemically stable thermal insulation materials but their application is hindered by brittleness low strength. Flexible nanostructure-assembled compressible have been developed to overcome the they still show strength, leading insufficient load-bearing capacity. Here we designed fabricated a laminated SiC-SiOx nanowire aerogel that exhibits reversible compressibility, recoverable buckling deformation, ductile tensile simultaneous high...
Abstract High mechanical load‐carrying capability and thermal insulating performance are crucial to thermal‐insulation materials under extreme conditions. However, these features often difficult achieve simultaneously in conventional porous ceramics.

Carbon aerogels are elastic, mechanically robust and fatigue resistant known for their promising applications in the fields of soft robotics, pressure sensors etc. However, these generally fragile and/or easily deformable, which limits applications. Here, we report a synthesis strategy fabricating highly compressible fatigue-resistant by assembling interconnected carbon tubes. The tube demonstrate near-zero Poisson's ratio, exhibit maximum strength over 20 MPa completely recoverable strain...
SiC ceramics are attractive electromagnetic (EM) absorption materials for the application in harsh environment because of their low density, good dielectric tunable performance, and chemical stability. However, performance current SiC-based to absorb EM wave is generally unsatisfactory due poor impedance matching.
