Carbon nanoballs and tungsten nanocrystal encapsulated carbon nanoballs were in-situ synthesized by heating starting materials in a transmission electron microscope. The carbon nanoballs of a few nm in diameter were structured by 1 to 5 layers of carbon shells. For the tungsten nanocrystal encapsulated carbon nanoball, the motion (moving, vibration and/or rotation) was in-situ confirmed at elevated temperatures, which might suggest a new possibility of the organic-inorganic composite materials.
