Since 2004, materials scientists and nanotechnology experts have been excited about a special of arrangement of atoms called a "coherent twin boundary" that can add enormous strength to metals like gold and copper. The CTBs are described as "perfect," appearing like a one-atom-thick plane in models and images. New research shows that these boundaries are not perfect. Even more surprising, the newly discovered kinks and defects appear to be the cause of the CTB's strength.
