Flexible Diamonds
Scientists from Carnegie Institution of Science developed a technique that predicts the ordered creation of strong, yet flexible, diamond nanothreads at 13 IDD and 16 IDB. The innovation will make it easier for scientists to synthesize nanothreads—an important step toward applying the material to practical problems in the future.
