Ever played Fallout? There’s always a nuke nearby in Fallout.
n 2008, Fanny Beron from the École Polytechnique de Montréal and colleagues devised CoFeB nanowires. They eventually found the best composition to be Co94Fe5B1, but not before going through a long process of trial and error. While testing the magnetic properties of the films, some inevitably blew off. During one such moment, Beron used an electron scanning micrograph to record the explosion that happened when a CoFeB magnetic array was overloaded.
