    Online Presentations | 05 Apr 2006 | Contributor(s):: Ki-Ho Lee, Jason Myers, Susan Sinnott

    Carbon nanotubes (CNTs) have generated a great deal of interest due to their unique properties. In this study, we examine the transport properties of various nanotubes using REBO-MD to determine the effects of diameter and chirality on transport mode. Both oxygen and methane were diffused through...
