Aluminum alloys have numerous technical advantages that made them one of the dominant structural material families of the 20th century. Aluminum has low density (2.71 g/cm3) compared with competitive metallic alloy systems. It also has good inherent corrosion resistance because of the continuous, protective oxide film that forms very quickly ...

The discovery of fullerenes in 1985 by Curl, Kroto, and Smalley, culminated in their Nobel Prize in 1996. Fullerenes, or Buckminsterfullerenes, are named after Buckminster Fuller, the architect and designer of the geodesic dome, and are sometimes called bucky balls. The names derive from the basic shape that defines fullerenes; ...
