description Dan Shechtman Overview
Dan Shechtman is an Israeli scientist who received the 2011 Nobel Prize in Chemistry for his discovery of quasicrystals, materials exhibiting non-repeating, ordered atomic structures that challenged conventional crystallography.
help Dan Shechtman FAQ
What did Dan Shechtman discover?
Dan Shechtman discovered quasicrystals, solid materials with ordered atomic patterns that do not repeat periodically. That finding challenged the old crystallography rule that crystals had to be periodic.
When did Dan Shechtman win the Nobel Prize?
He received the 2011 Nobel Prize in Chemistry for the discovery of quasicrystals. The award recognized work that began with electron microscopy observations in the early 1980s.
Why was Shechtman's discovery controversial?
Many scientists initially rejected quasicrystals because the diffraction patterns did not fit accepted crystallographic rules. Linus Pauling was famously skeptical, but later evidence confirmed Shechtman's interpretation.
Where has Dan Shechtman worked?
Shechtman is strongly associated with the Technion, Israel Institute of Technology. His quasicrystal discovery was made while he was working in the United States at what was then the National Bureau of Standards.
