National Institute of Standards and Technology | NIST Colloquium Series: Quasi-Periodic Materials, Dan Shechtman @NIST | Uploaded July 2015 | Updated October 2024, 14 hours ago.
A revolution in our understanding of crystallography happened with the discovery, in 1982, of the Icosahedral phase (the first quasi-periodic crystal) by Dr. Dan Shechtman while he was working as a guest researcher at NIST, then known as the National Bureau of Standards. It is clear now that although most crystals are ordered and periodic, a good number of them are ordered and quasi-periodic. Quasi-periodic materials have developed into an exciting interdisciplinary science. Nobel Laureate Dan Shechtman outlines the discovery of Quasi-periodic crystals and discusses their structure and the role of transmission electron microscopy in the discovery.
