Each new quasicrystal discovery unveiled yet another unique, quasi-kaleidoscopic atomic structure once thought to be impossible in natural or anthropogenic matter. “In terms of quasicrystals, we had ...
The red trinitite sample that contained the quasicrystal. It was formed in the aftermath of the first nuclear detonation in 1945—the famous Trinity Test at the Alamorgordo Bombing Range in New ...
Quasicrystals are bizarre, rare, mysterious materials blending mathematical order and irregularity. A new, unexpected material halfway between a regular crystal and a quasicrystal may help reveal ...
The quasicrystal within the rock is a known type, Al 63 Cu 24 Fe 13, first synthesized in a lab in 1987.However, if the Russian rock is as similar to a chondrite meteorite as its composition ...
STUNNED scientists have discovered a new ‘quasicrystal’ that formed during the first nuclear bomb test in 1945. The Trinity test may have occurred over 75 years ago but researchers have… ...
A quasicrystal's atoms can be arranged in ways not found in normal crystal; For years researchers believed quasicrystals could only be made artificially; By ABIGAIL BEALL FOR MAILONLINE .
The quasicrystal has equally-spaced atomic layers, each with a 12-fold rotational symmetry – something that is impossible in ordinary crystals with translational symmetry. Read more. Quasicrystalline ...
Two years after identifying the Russian rock's unusual composition, a team of scientists thinks it has nailed down its otherworldly origin.
Now Yaacov Kraus, Oded Zilberberg and colleagues at Israel’s Weizmann Institute of Science have shown that a similar 2D topological effect can be seen in how light propagates in a 1D quasicrystal – ...
