Scratching the surface: a simple needle-scratching method (NSM) generates large-area catalyst patterns on solid substrates for the growth of densely aligned single-walled carbon-nanotube (SWCNT) arrays by chemical vapor deposition (CVD, see picture). A high density of well-aligned, ultralong SWCNTs...
