When Israeli scientist Daniel Shechtman first saw a quasicrystal through his microscope in 1982, he reportedly thought to himself, “Eyn chaya kazo” – Hebrew for, “There can be no such creature.”But th...

Scientists challenged this once–believed universal law of nature when they discovered an “impossible” material whose existence could not be explained by periodic arrangement of atoms. These materials,...
Icosahedral clusters, icosaheral order and stability of quasicrystals—a view of metallurgy
stable quasicrystal isodahedral cluster valence concentration phason disorder；icosahedral order
2010/10/13
We review the stability of various icosahedral quasicrystals (iQc) from a metallurgical
viewpoint. The stability of stable iQcs is well interpreted in terms of Hume-Rothery rules,
i.e. atomic size f...
Software package for structure analysis of quasicrystals
software quasicrystals structure analysis
2010/10/13
Recently a software package for the structure analysis of quasicrystals has been released,
giving a better environment for determining quasicrystal structures. Therefore we can analyze
their structu...
29 March 2007,Physicists in the US have found that they can transmit terahertz light at selective wavelengths by shining it onto a metal film perforated in an aperiodic, "quasicrystal" pattern. Until ...
