Shape Matters in the Case of Cobalt Nanoparticles

Caption

These cubes of cobalt (left/top), measuring about 50 nanometers wide, are showing scientists that, on the nanoscale, a change in shape is a change in property. Unlike smaller spherical cobalt nanoparticles, nanocubes melt and fuse (right/bottom) when illuminated by a transmission electron microscope and possess different magnetic characteristics than the nanospheres as well.
