She drew inspiration from her work at Harvard University where she researched nanofabrication and characterization of quasicrystal
metasurfaces using shadow-sphere lithography.
Analysis of an endlessly single-mode penrose-tiling photonic quasicrystal
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 only naturally occurring quasicrystal
found to date may well have come from an asteroid.

1-CS-coke sample; 2-Nc-the average lattice number in a quasicrystal
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.
1985) Crystal and quasicrystal
structures in Al-Mn-Si alloys.
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.
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.
