Paper waste converted into eco-friendly aerogel

Known as "frozen smoke" because of their milky translucent appearance, aerogels are among the world's lightest solid materials. Consisting of 99.8 percent air, they're highly heat-resistant and are an excellent form of insulation. Now, scientists at the National University of Singapore (NUS) have used paper waste to create one.Read More
