ending the night with some science
On the right is a carbon nanotube composed entirely of hexagons and was inserted pre-bent at 25 degrees. On the left is a carbon nanotube comprised of pentagon and heptagon defects in the lattice to create a similar bend. Simulating both tubes shows that the tube containing the lattice defects remains rigid while the other tube oscillates.
Studying the effects of lattice defects is an important part of nanotube science. I have also been experimenting with using them to create a heterojunction.
Here I have highlighted the lattice defects. The inspiration for this has come from here and David Tomanek's Nano-Velcro.
