    • The nanotube deposits were generated in an arc (20 V, 100 A) between a 7-mm-diameter graphite anode and a 2.5-cm-diameter graphite cathode in a 500 mb He atmosphere. The samples were analyzed with scanning microscopy (JSM 6330F) and high-resolution TEM (JEM-3010 URP, 0.17-nm point resolution) at Campinas, Brazil; low-resolution TEM images were analyzed with a JEOL 100CX II at Georgia Tech. Individual nanotube-containing carbon columns were glued with silver paint on conventional TEM copper grids and suspended over the grid holes. It must be emphasized that the sample must be prepared with extreme care to minimize the manipulation of the individual carbon columns and conserve the pristine surface where the beaded NTs are present.

    • The evaporation rate is estimated from the vapor pressure by noting that, in thermodynamic equilibrium with the vapor (and a unit sticking coefficient), the rate of atoms arriving on the surface is balanced by an equal rate of evaporated atoms (21).
