Scientists at TU Wien have developed a technique to control the shape and size of nano gold structures using highly charged ions. The experiment shows that the impact force is not the decisive factor, but rather the electrical charge of the ions, which deposits energy at the point of impact and disrupts the crystal structure of the gold.
