High resolution transmission electron microscopy (HRTEM) was used to characterize the multiwalled graphitic shell structures which were found in the cathodic deposits produced under specific arc-discharge conditions (with carbon as cathode and a palladium tube filled with MoS~2 as anode). a variety of polyhedrons consisting of multiwalled graphitic shell of sizes ranging from ~2nm to more than 20nm was revealed. A novel phenomenon of "out-of-shell growth" of the self- assembled polyhedron was examined and the growth mechanism was discussed.
