Stable hexagonal non‐close‐packed (ncp) gold nanowires with a diameter of about 50 nm and aspect ratios of well over 400 are fabricated by Hyunjung Shin and co‐workers, as described in article number 1706261 . Single‐crystalline gold nanowires are grown in the confined system of nanotubular TiO 2 arrays, and some of them are demonstrated to have 6‐fold rotational symmetry, observed by TEM tilting experiments. Nucleation events of very small face‐centered cubic or ncp Au seeds are expected to occur on the inner surfaces of the TiO 2 nanotubes and subsequently grow by a diffusion‐limited process.
