This study investigated new sol-gel methods in the fabrication of Al₂O₃ - SiO₂ composite aerogels. Compared to conventional methods, the Al₂O₃ - SiO₂ composite aerogels were prepared and mixed together. Thermal conductivity of the composite aerogels was measured by an instrument, using a ...
Aerogels are promising thermal insulators because of their low thermal conductivity, durability and eco-friendly nature. However, aerogels become a problem because of their highly flammable properties. In this study, flame retardant cellulose insulators were formed from scrap pieces of cotton. Firstly, an NaOH/Urea solution ...
Clay aerogels are typically used for insulation, filtration and absorption, and are typically favored because of their eco-friendly nature, low density and high porosity. Unfortunately, these aerogels are limiting due to their relatively high fragility. Researchers in this study aimed to create fracture-free pectin/clay ...
Due to their high compressibility and resilience, nanofibrous aerogels (NFAs) have been proven to have positive insluative impacts on various applications with electronics and material damping. Up until this study, the fabrication of such nanofibers had proven to be very difficult. The scientists of this ...
Highly porous aerogels can be employed in a variety of applications; notably for this study, oil/water separation and sound absorption. Because of their poor mechanical functions, aerogels are limited within their array of applications. In this study, researchers set out to improve the mechanical ...
