3D Self‐Assembly: Self‐Organized Origami Structures via Ion‐Induced Plastic Strain (Adv. Mater. 1/2013)

With the advent of nanotechnology, metals will have to be processed at a much smaller scale and new engineering concepts are required. On page 91, Khattiya Chalapat and co-workers demonstrate the assembly of metallic nano-3D-structures by plastic deformation that is induced either on the surface by reactive ion etching or within the metal matrix by focused ion beam. The front cover image illustrates a metallic nanocubic structure being unfolded by an ion beam.
