Double-walled carbon nanotubes, 90% (OD: 2-5 nm, Length: 1-2 um)

CNT100 - Double-walled carbon nanotubes are coaxial nanostructures composed of exactly two single-walled carbon nanotubes, one nested in another.

Double-walled carbon nanotubes, 90% (OD: 2-5 nm, Length: 1-2 um) - can adopt four distinct permutations arising from the electronic type (metallic or semiconducting) of their inner and outer walls.
