Phys.org August 2, 2024 Researchers in China demonstrated an interpenetrated multinetwork hybrid aerogel realizing thermal insulation, flame retardancy, and high compression modulus. One-dimensional hydroxyapatite nanowires (HAP) formed a three-dimensional interpenetrated multinetwork structure to optimize the thermal conductivity. The multinetwork hybrid aerogels exhibited thermal insulation performance in room temperature and enhanced ultrahigh compression modulus, flame retardancy and self-extinguishing smoke suppression properties. According to the researchers multinetwork hybrid aerogels are promising candidates for efficient heat insulation, fire prevention, and robust applications… read more. TECHNICAL ARTICLE

The lightest shielding material in the world
EurekAlert July 2, 2020 An international team of researchers (Switzerland, Singapore) used nanofibers of cellulose as the basis for making an aerogel which is a light, highly porous material. Cellulose fibres obtained from wood enable a wide range of chemical modifications. The composite of cellulose nanofibers and silver nanowires created ultra-light fine structures which provide excellent shielding against electromagnetic radiation. The material has a density of 1.7 milligrams per cubic centimeter, achieves more than 40 dB shielding in the frequency range of high-resolution radar radiation (8 to 12 GHz) – in other words: virtually all radiation in this frequency range […]
