Ceramic aerogels are attractive for thermal insulation but plagued by poor mechanical stability and degradation under shock. In this study, we designed synthesized hyperbolic architectured ceramic with nanolayered double-pane walls a negative Poisson's ratio (-0.25) linear expansion coefficient (-1.8 × 10-6 per °C). Our display robust feature ultralow densities down to ~0.1 milligram cubic centimeter, superelasticity up 95%, near-zero strength loss after sharp shocks (275°C second) or...
