crystal lattice

n.
A geometric arrangement of the points in space at which the atoms, molecules, or ions of a crystal occur. Also called space lattice.

crystal lattice

n
(Chemistry) the regular array of points about which the atoms, ions, or molecules composing a crystal are centred

(ˈlæt ɪs)

n., v. -ticed, -tic•ing. n.
1. a structure of crossed wooden or metal strips usu. arranged to form a diagonal pattern of open spaces between the strips.
2. a window, gate, or the like consisting of such a structure.
3. an arrangement in space of isolated points in a regular pattern, showing the positions of atoms, molecules, or ions in the structure of a crystal.
4. a partially ordered set in which every subset containing exactly two elements has a greatest lower bound or intersection and a least upper bound or union.
v.t.
5. to furnish with a lattice or latticework.
6. to form into a lattice.

Okamoto of Ibaraki University in Japan and his colleagues now have gleaned new details about the size, composition, and crystal structure of dust within the Beta Pictoris disk, suggest the location of a possible planet as well as of a trio of asteriod or comet belts.
Some of the more important ways in which texture influences materials behavior and properties include: the link between crystal structure and crystal morphology and the use of crystal morphology to create texture; the effect of texture on tensor properties of bulk and thin film ceramics and metals, e.g., piezoelectric constants, elastic coefficients; and the effect of texture on the intensities of diffraction peaks.
For example, Olsen and Roth (69) determined the crystal structure of [BaNd.sub.2][Ti.sub.3][O.sub.10] by electron diffraction and high-resolution electron microscopy to be monoclinic instead of the reported orthorhombic symmetry.
These new results underline the central role of hybrid modes for the stabilization of the crystal structure, in agreement with theoretical calculations.
