چکیده
Self-assembly of carbon nanotubes Introduction This talk addresses the self-assembly of carbon nanotubes (CNTs). In order for useful and potentially important structures and devices to be built from CNTs it is essential that the nanotubes be manipulated and organized in some way. One of the most promising routes to such structures and devices appears thus far to be self-assembly. While acknowledging that there are two types of CNTs – multiwalled (MWNTs) and single-walled (SWNTs) – the work reviewed here will deal almost exclusively with SWNTs. Within the family of SWNTs there exist nanotubes that are either metallic or semiconducting. These electronic properties are of fundamental importance when considering certain applications, but for the self-assembly work that will be discussed here the nature of the tube itself is somewhat ignored.

Self-assembly of diphenylalanine backbone homologues and their combination with functionalized carbon nanotubes.
The integration of carbon nanotubes (CNTs) into organized nanostructures is of great interest for applications in materials science and biomedicine. In this work we studied the self-assembly of β and γ homologues of diphenylalanine peptides under different solvent and pH conditions. We aimed to investigate the role of peptide backbone in tuning the formation of different types of nanostructures...
متن کاملMesoscale modeling of mechanics of carbon nanotubes: Self-assembly, self-folding and fracture
Using concepts of hierarchical multi-scale modeling, we report development of a mesoscopic model for single wall carbon nanotubes with parameters completely derived from full atomistic simulations. The parameters in the mesoscopic model are fit to reproduce elastic, fracture and adhesion properties of carbon nanotubes, in this article demonstrated for (5,5) carbon nanotubes. The mesoscale model...
