Analysis of an endlessly single-mode penrose-tiling photonic quasicrystal
In contrast, the units in a quasicrystal
, short for "quasiperiodic crystal," are formed from units with symmetries that don't occur in normal crystals (SN: 1/23/99, p.
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.

For Ca-montmorillonite the lamellae are held within a potential well even in distilled water and the quasicrystals
are therefore stable; however, dispersion of these entities takes place at about 2 mmol(+)/L, which is obviously much greater than required to initiate swelling between the lamellae composing a quasicrystal
, since these are retained in the potential well even in distilled water.
Liam thought of dusting the EmDrive's interior lining with icosahedrite, a quasicrystal
with fivefold symmetry, which he and Jillian talked about before their day at work started.
