While some researchers are developing hydrophobic surfaces and coatings in order to prevent foggy or frozen windows, researchers at the Fraunhofer Institute for Surface Engineering and Thin Films (Fraunhofer IST) in Braunschweig decided to take on a different approach. They developed a transparent and heatable film which ensures there’s no condensation or ice on windows…. »

A thin film based on carbon nanotubes (CNT) could replace conventional magnetic loudspeakers. By applying an audio frequency current through the CNT, the loudspeaker can generate sound with wide frequency range, high sound pressure levels (SPL), and low total harmonic distortion (THD). The uniqueness of this advancement is that the films are flexible, stretchable, transparent,… »
