  • IBM researchers have produced a breakthrough technique that allows scientists to create nanoscale objects.

    The first mission was to produce the smallest ever 3D map of the world. Using a heated nanoscale silicon tip researchers carved a 22-by-11 μm 3D model of the world. At this size, 1,000 world maps could fit on a grain of salt. One thousand metres of altitude correspond to roughly 8nm.

  • Using this technique, researchers created a 25nm-high replica of the 4,478-metre tall Swiss peak Matterhorn.
