| Carbonaceous materials, such as activated carbon, have long been known to possess gnano-spacesh where a variety of materials can be accommodated. However, mechanism to store objects is not yet fully understood. We visualized, for the first time, how the materials were stored in the inner-spaces of nano-carbons, using single-wall carbon nanotubes and nanohorns, into which C60 were incorporated by the liquid-phase methods [1]. Their structures observed with HRTEM proved that the nanometer-scale holes were indispensable for C60 to be stored inside carbon nano-pores and that the adsorption rate of C60 was largely dependent on the nano-scale curvature of graphitic planes composing the nano-spaces. The works presented here will lead to a future development of designed porous nano-carbon materials that could selectively store molecules for a specific purpose. [1] M. Yudasaka, K. Ajima, K.
