Abstract: At room temperature, glasses are known to be brittle and fracture upon deformation. Zhenget al. show that, by exposing amorphous silica nanostructures to a low-intensity electron beam, it is possible to achieve dramatic shape changes, including a superplastic elongation of 200% for nanowires.
