[ODCAD] Nano conveyor of Metal
Source: Chemical Eng. News, May 3, 2004
Scientists from Univ. of Californian, Berkeley and Lawrence Berkeley National Lab have found a way to transport molten metal along nanotube.
Physics professor Alex Zettl, postdoc Christ Regan and their coworkers applied electrical current to a multiwalled carbon nanotube (MWNT), and the heat generated can melt contacting metal crystal. The metal then migrate along the tube from the anode to the cathode. The metal particles are shuttled along the surface of the nano tube in atomic form without evaporation. They observed that the metal can move over a greater distance than 2 um.
Potentially, this may be useful technology to make nano circuit or nano device combining metal with nano tube.
