Crimp junctions for perpendicular carbon nanotube scaffolding

Crimp junctions for perpendicular carbon nanotube scaffolding

Damian Gregory Allis, Ph.D.: In this design, two rigid diamondoid rings are fused at a quasi-tetrahedral junction and sized, through the addition or subtraction of repeat subunits in each ring, to accommodate two carbon nanotubes of different diameters. The crimping of the nanotubes is a result of van der Waals packing of the rings, a feature that can be enhanced or removed by adjusting the ring size. (grey = carbon, white = hydrogen, blue = nitrogen, red = oxygen).

All images (in this series) are the result of molecular mechanics structure calculations using either Tinker (MM2 parameters) or NAMD (CHARMM). Images were made with VMD. Any inquiries concerning methods, software, or shop talk are directed here.

And read his response to my question “If you had the attention of the entire world, what would you say regarding molecular manufacturing?” here

As with previous pictures, I will post the others in this series over time. To see it all now, visit the Nanotechnology Now Gallery.
