The rock has been designated as a (https://www.ancient-origins.net/news-science-space/meteorite-found-siberia-contains-naturally-impossible-crystal-00495) quasicrystal
because of its unique structural properties.
At the high-temperature limit of 858[degrees]C, the diffusivity does not prevent the supply of Al and O, thus, the surface film establishes a stoichiometric condition, which favors crystallization, correspondingly, and the oxidation of the clean pentagonal surface of [Al.sub.63][Cu.sub.25][Fe.sub.12] quasicrystal
leads to the growth of an amorphous oxide layer, very fine film type.
A one-dimensional hexagonal piezoelectric quasicrystal
medium of a point group 6 mm which is initially in a reference undisturbed stress-free state is studied here.
Analysis of an endlessly single-mode penrose-tiling photonic quasicrystal
For example, atomic crystals can have various irregularities, such as defects and edge dislocations, and also quasicrystal
structures, which have long-range orientational order but no translational symmetry [12,13].
analyzed in  has decagonal symmetry and in this case [R] should have the form [18, 26-28],
The comparison between subliminally perceived quantal maps and previous cortical maps stored in synaptic networks occurs by quantal non-local quasicrystal
tiling effect which mediates the activation and deactivation of synapses through contraction and growth of dendritic spines.

The fifteenth century is not scientifically hollow either: for example, one finds a host of intricate design patterns in Islamic architecture of the period that exhibit surprisingly advanced decagonal quasicrystal
geometry--a concept discovered by Western mathematicians and physicists only in the 1970s and 1980s.
Some of the coatings are listed as follow: hydroxyapatite coating (Lin et al, 2001; Chu et al, 2001; pfaff et al, 1993), bioceramics (Hench, 1991; Lugscheider et al, 2001), sol-gel coatings (Chai et al, 2001), quasicrystal
thin films (Symko et al, 2001), functionally graded materials coatings (Khor & Wang, 2001), graded coatings (Park & Condrate, 1999), composite coatings (Wang et al, 2000; Breme et al, 2000) and biomimetic coatings (Li et al, 2001; Li et al, 2002).
The discovery of quasicrystal
(1) phases has been reported in 1984.
