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

Joint research team develops edge-to-edge assembly technique for 2D nanosheets
Phys.org February 2, 2024 Despite remarkable advancements, the controlled assembly of highly anisotropic 2Dnanosheets is significantly challenging, primarily due to the limited availability of selective edge-to-edge connectivity compared to the abundant large faces. Researchers in South Korea have shown controlled self-assembly of 2D-silica nanosheets (2D-SiNSs) into hollow micron-sized soccer ball-like shells (SA-SiMS). The assembly was driven by the physical flexibility of the 2D-SiNSs and the differential electric double-layer charge gradient creating electrostatic bias on the edge and face regions. The resulting SA-SiMS structures exhibited high mechanical stability, even at high-temperatures, and exhibited excellent performance as catalyst support in the dry […]
