Three examples of partitioning carbon nanotubes in liquid phases. Left, nanotubes partitioned by diameter. Smaller diameters, on the bottom, appear purple. Center, partitioned between semiconductors (amber, top) and metals. Right, a sample with different diameter range partitioned between metals (yellow) and semiconductors. Color differences are due to differences in electronic structure. Photo by Baum/NIST
