    • 2014 December 1, Mike Williams, “Microbullet hits confirm graphene’s strength”, in Rice University‎[1]:
      As a microbullet impacts the graphene, the diameter of the cone it creates – determined by later examination of the petals – provides a way to measure how much energy the graphene absorbs before breaking.
    • 2016 January 14, Jessica Hall, “Nanoengineers build 'microcannons' that fire light-up bullets filled with drugs”, in ExtremeTech‎[2]:
      PFC vaporizes when hit with an ultrasound pulse, producing rapidly expanding gas bubbles that "fire" the nanobullets out of the microcannons at speeds on the order of meters per second -- and the fluorescent microbullets light up to show exactly where they landed in the tissue target.
