A structural form of matter that is less orderly than a crystal and more orderly than a glass.

(ˌkweɪ zaɪˈcrys tl, ˌkweɪ saɪ-, ˌkwɑ si-, -zi-)
n.
a form of solid matter whose atoms are arranged like those of a crystal but assume patterns that do not exactly repeat themselves.

They can study quasicrystals in metallic alloys, which have no discernible pattern when viewed in 3D space but when one looks at them in higher virtual dimensions, they actually exhibit regular patterns.
This graduate text introduces the mechanisms of glass formation related to the stability of the supercooled liquid, particularly the limiting of crystal nucleation and the limiting of their growth in relation to the formation of crystals and quasicrystals, and describes the structural changes that occur in metallic glasses during heating.
Another theme of the proposed research lies in the mathematical theory of quasicrystals.
The self-described comic book fan said she began drafting her thesis on quasicrystals -- a subset of crystals that diverge from the usual structural characteristics of crystals.
Aperiodic tilings are often used as models of quasicrystals; when Dan Shechtman and his co-authors made the Nobel prize-winning discovery of quasicrystals in [19], the first sign by which they knew that they had found something special was the presence of tenfold rotational symmetry in the X-ray diffraction patterns.
Researchers at the University of Lorraine in France say that quasicrystals, a type of complex metal alloy with crystal-like properties, can be useful in the design of new composite materials for this purpose.

Contributed by scientists from Europe, Asia, and the US, the 30 chapters explain the surface properties of alloys, the properties of surface alloys, surfaces of compound semiconductors, the physical properties of surface silicides, the properties of oxide surfaces, and surfaces of simple ionic crystals, ice, quasicrystals and related intermetallic alloys, and amorphous/glassy materials.
