'2-faced' Bioacids Put a New Face on Carbon Nanotube Self-Assembly

Nanotubes, the tiny honeycomb cylinders of carbon atoms only a few nanometers wide, are perhaps the signature material of modern engineering research, but actually trying to organize the atomic scale rods is notoriously like herding cats. A new study* from the National Institute of Standards and Technology and Rice University, however, offers an inexpensive process that gets nanotubes to obediently line themselves up -- that is, self-assemble -- in neat rows, more like ducks.
