The Aerogel Revolution: RWTH Aachen’s Bid to Decarbonize Performance Materials
The quest for the perfect insulator has long been a battle against the second law of thermodynamics, but a new class of «frozen smoke» fibers is promising to keep us warm without the carbon cost. For decades, aerogels—often called «frozen smoke» because they are composed of over 90% air—were the darlings of aerospace engineering but […]
