Going out on a limb : A combination of theoretical techniques, high‐resolution microscopy, and energy‐dispersive X‐ray spectroscopy shows the role sulfur plays in branching phenomena during carbon nanotube (CNT) network growth. A model is proposed in which small amounts of sulfur are enough to trigger the growth of a bud in a CNT, leading to kink formation and subsequent branch growth (see SEM image).
