A, Tensile pressure–pressure dependence of silanized (stable strains) and unmodified (dashed strains) aerogels with different porosities. The inset demonstrates a SiCellA sample held amongst tensile mechanical clamps for the duration of measurements. b, Compressive pressure–strain dependence of aerogels with distinctive porosities. The inset exhibits a SiCellA sample held between comp... https://georger691lwj8.wikissl.com/user
