A multidisciplinary team of researchers at Lawrence Livermore National Laboratory (LLNL) developed a new type of electrically controlled, near-infrared smart window that can cut near-infrared light transmission by almost 50%. Their secret ingredient? Vertically aligned carbon nanotubes—tiny, tube-shaped structures made from carbon atoms that are thousands of times thinner than a human hair. The research was published in Nano Letters.
