"Carbon Nanostructures in Different Configurations"
Prof. Rod Ruoff
Northwestern University

Are carbon nanotubes ever cylindrical, given that they are often treated as such in models? The static deformations exhibited by CNTs in real environments are presented, which leads to a discussion of an interesting experimental challenge: precisely controlling the chemical transition state at particular reaction sites in nanostructures via applied mechanical deformation (a new way of doing chemistry). We then turn to a brief outline of work on graphene-based materials—of individual sheets and also of composites with functionalized graphene sheets as filler material, and finish with discussion of recent progress on fracture mechanics measurements of individual carbon nanotubes.
