Scientists are reporting the development of a new, ultra-light form of "frozen smoke" -- renowned as the world's lightest solid material -- with amazing strength and an incredibly large surface area. The new so-called "multiwalled carbon nanotub...
Aluminum -- one of nature's best conductors of electricity conductors of electricity -- may behave like a ceramic or a semiconductor in certain situations, according to an Ohio State University scientist and his colleagues. Among the findings that appear in the current issue of the journal Science: When it comes to forming tiny structures in computer chip circuits and nanotechnology, aluminum may endure mechanical stress more than 30 percent better than copper, which is normally considered to be the stiffer metal
