Samples of the new ceramic aerogel, which is incredibly lightweight and can withstand intense heat fluctuations(Credit: Oszie Tarula/UCLA)Ceramic aerogels have been protecting industrial equipment and space-bound scientific instruments for decades, thanks to their incredible lightness and ability to withstand intense heat. The problem is they can be pretty brittle. Now, a team led by researchers at the University of California Los Angeles (UCLA) has developed a new ceramic aerogel that's far hardier and more flexible, even after repeated exposure to wild temperature swings.Aerogels are strong, solid structures that are up to 99 percent air by volume, which of course makes them incredibly lightweight. They can be made of many different types of materials, but ceramics are particul...
