Chlorosulfonic

The researchers took advantage of novel cryogenic techniques for electron microscopy that allowed them to directly image the graphene sheets in the chlorosulfonic acid. ❋ Unknown (2010)

"Just adding the nanotubes to chlorosulfonic acid results in dissolution, without even mixing," he said. ❋ Unknown (2010)

While earlier research had focused on single-walled carbon nanotubes, the team discovered chlorosulfonic acid is also adept at dissolving multiwalled nanotubes (MWNTs). ❋ Unknown (2010)

Solvent found (chlorosulfonic acid) to untangle carbon nanotubes in solution ❋ Unknown (2010)

Pasquali, primary author Nicholas Parra-Vasquez and their colleagues reported this month in the online journal ACS Nano that chlorosulfonic acid can dissolve half-millimeter-long nanotubes in solution, a critical step in spinning fibers from ultralong nanotubes. ❋ Unknown (2010)

A few years ago, the Rice researchers discovered that chlorosulfonic acid, a "superacid," adds positive charges to the surface of the nanotubes without damaging them. ❋ Unknown (2010)
