Nanostructure strength goes under the microscope

Abstract:
Researchers at Northwestern University, US, have made a microelectromechanical systems (MEMS) device that enables mechanical testing of nanostructures while they are under constant observation in a scanning or transmission electron microscope (S/TEM). By using the technique on multiwalled carbon nanotubes, they discovered that the crystalline nanotubes became amorphous on tensile failure.
