Aerogels are extraordinary materials that have set Guinness World Records more than a dozen times, including as the world’s lightest solids.
Professor Markus Niederberger from the Laboratory for Multifunctional Materials at ETH Zurich has been working with these special materials for some time. His lab specialises in aerogels composed of crystalline semiconductor nanoparticles. “We are the only group in the world that can produce this kind of aerogel at such high quality,” he says.
