2011 Chemistry Nobel Prize Resources
AIP is honored to count Professor Shechtman among its journal authors and has made the papers he has authored in AIP publications freely available until the end of 2011.
» Overview The 2011 Nobel Prize in Chemistry was awarded to Daniel Shechtman, a distinguished professor at the Israel Institute of Technology in Haifa, "for the discovery of quasicrystals." The discovery was published in the American Physical Society's journal Physical Review Letters in 1984. In all ordered materials composed of crystals, there are ordered, repeating arrays of atoms. A material's periodicity is created by translational and rotational symmetries which are repeated throughout the material.
At the time of the discovery, Professor Shechtman was on sabbatical from the National Institute of Standards and Technology (NIST), which at that time was the National Bureau of Standards (NBS). The discovery forever changed the definition of crystallinity. Researchers came to realize that they could not know what physical parameters rigorously define a crystal.

The American Institute of Physics is proud to present resources on this year's Nobel Laureate in Chemistry, Daniel Shechtman from Technion–Israel Institute of Technology, Haifa, Israel for "the discovery of quasicrystals."
Scientists use x-ray and electron diffraction to investigate the structure of a crystal. Professor Shechtman's measurements were instrumental in destroying the notion that it was periodicity that formed the diffraction pattern. Quasicrystals showed patterns, but no periodicity. But the type of symmetry discovered by Professor Shechtman was seemingly impossible according to what was then understood about the nature of crystallography. The spacing between atoms was too small to accommodate this so-called tenfold symmetry. Shechtman showed that the atoms in a crystal could be packed in a pattern that never repeated, yet had a well-defined symmetry.
These unique materials also have unique properties. In spite of their composition of mostly transition metals—whose properties generally include high thermal and electrical conductivities—quasicrystals often exhibit low thermal and electrical conductivities. In addition to their unique transport properties, these materials exhibit interesting physical properties as well. For example, their hardness is useful to strengthen materials, such as structural steel, and their low sticking coefficient makes them ideal as coatings for turbines.
