(a) Construction of a helical nanowire by the entanglement of Boerdijk-Coxeter-Bernal helices. In the figure, two BCB structures are shown before and after the entanglement. (b) Simulated STEM image of the model. (c) Simulated diffraction pattern of the structure. (d) A model of the decahedral nanowire structure. (e) Simulated image of the decahedral nanowire structure. (f) Simulated diffraction pattern of the decahedral nanowire structure
