From: Mechanochemical route to the synthesis of nanostructured Aluminium nitride
27Al NMR spectra of the samples after various milling times: (a) 4 h, (b) 5 h and (c) 6 h. Minor peaks equally distant from the central lines are from spinning side bands. The spectra are normalized to maximal intensity. (d) Schematic structural evolution of Al during milling.
