Opening the window: Hollow multilayer nano-octahedra (see TEM image and structure) often appear in the laser-ablation products of layered transition-metal chalcogenides. Calculations on MoS2 nanoparticles demonstrate that nano-octahedra exist in a window of stability between nanoplatelets and spherical fullerene-like nanoparticles.
