The shorter, the more dispersible : An iterative, emulsion‐based shortening technique has been used to reduce the length of single‐walled carbon nanotubes (SWNTs) to the same order of magnitude as their diameter (ca. 1 nm), thus achieving an effectively “zero‐dimensional” structure with improved dispersibility and, after hydroxylation, long‐term water solubility. Finally, zero‐dimensional SWNTs were positively identified using mass spectrometry for the first time.
