Applications of Aerogel Researchers are working to develop new applications for Aerogel, ranging from the next-generation tennis rackets to super-insulated space suits for a manned NASA mission to Mars. Aerogel is also described by scientists as the “ultimate sponge”, with its many nano-sized pores making it ideal for absorbing pollutants in air and water. According to researchers, Aerogel can also be used to make hydrogen-based fuels. A version of Aerogel made from Platinum can be used to speed up the production of hydrogen. The hydrogen fuel can then be used as a replacement to carbon-based fossil fuels. Other uses include mountaineering. Last year a Mount Everest climber used Aerogel insoles, as well as sleeping bags lined with the material. Her comment: "The only problem I had was that my feet were too hot, which is a great problem to have as a mountaineer.” Research is also being done in the Semiconductor Industry to make newer, faster next-generation computer chips. Description Taken from: "Aeroge l - From Wikipedia, the free encyclopedia " Aerogel is a low-density solid-state material derived from gel in which the liquid component of the gel has been replaced with gas. The result is an extremely low density solid with several remarkable properties, most notably its effectiveness as an insulator. It is nicknamed frozen smoke, solid smoke or blue smoke due to its semi-transparent nature and the way light scatters in the material; however, it feels like expanded polystyrene (Styrofoam) to the touch. Aerogel was first created by Steven Kistler in 1931, as a result of a bet with Charles Learned over who could replace the liquid inside a jam (jelly) jar with gas without causing shrinkage. Aerogels are produced by extracting the liquid component of a gel through supercritical drying. This allows the liquid to be slowly drawn off without causing the solid matrix in the gel to collapse from capillary action, as would happen with conventional evaporation. The first aerogels were produced from silica gels. Kistler's later work involved aerogels based on alumina, chromia and tin oxide. Carbon aerogels were first developed in the early 1990s. Properties To the touch, aerogels feel like a light but rigid foam, something between Styrofoam and the green floral foam used for arranging flowers. Despite what their name may suggest, aerogels are dry materials and do not resemble a gel in their physical properties but a nanofoam. (The name comes from the fact that they are derived from gels.) Pressing softly on an aerogel typically does not leave a mark; pressing more firmly will leave a permanent dimple. Pressing firmly enough will cause a catastrophic breakdown in the sparse structure, causing it to shatter like glass—a property known as friability. Despite the fact that it is prone to shattering, it is very strong structurally. Its impressive load bearing abilities are due to the dendritic microstructure, in which spherical particles of average size 2-5 nm are fused together into clusters. These clusters form a three-dimensional highly porous structure of almost fractal chains, with pores smaller than 100 nm. The average size and density of the pores can be controlled during the manufacturing pr... read more
