Indium(III) sulfide nanocoils can be synthesized at 180 °C (a), while increasing the temperature to 220 °C would result in SWNTs (b). Oriented attachments of nanocoils are found in some TEM images (d,e, side view; f, top view), suggesting a formation mechanism via the coiling of ultrathin nanocoils followed by oriented attachment (c). Scale bar: a,d,e,f, 50 nm; b, 100 nm.
