Review of Short Phrases and Links

    This Review contains major "Crystal Structure"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. A crystal structure is a concept fundamental to many areas of science and technology.
  2. Crystal Structure: The arrangement of ions, atoms, and molecules in a crystal.
  3. Crystal structure: the convolution of a lattice with a basis, e.g. (Web site)
  4. A crystal structure is the orderly geometric spatial arrangement of atoms in the internal structure of a mineral. (Web site)
  5. The crystal structure is one of the lattices with a unit cell, which contains atoms at specific coordinates, at every lattice point.

Crystal Structures

  1. Whether or not a material is polar is determined solely by its crystal structure.
  2. It provides information about how X-rays are generated and how Bragg's Law is derived and used for crystal structure determination.
  3. Crystal structure is orthorhombic.

Crystals

  1. Crystal structure and habit: See the above discussion of crystal structure.
  2. In solid-state physics, the free electron model is a simple model for the behaviour of valence electrons in a crystal structure of a metallic solid.
  3. The whole crystal structure is built by stacking these identical unit-cells together. (Web site)
  4. Crystal structure data are downloadable in CIF format, and users may upload crystal data as CIF or REF files. (Web site)
  5. The disorder affects the open circuit voltage, an important technological property for batteries as well as determining the equilibrium crystal structure.

Translational Symmetry

  1. The space group of the crystal structure is composed of the translational symmetry operations in addition to the operations of the point group.
  2. In many materials, there are actually a variety of solid phases, each corresponding to a unique crystal structure.
  3. This system allows the arrangement of the crystal structure data in such a way that both chemical and crystallographical relationships can be recognized.
  4. Unit Cell: The smallest parallelpiped shaped object which, when stacked repetitively in three dimensions, generates the entire crystal structure.
  5. Apart from the translational symmetry of the Bravais lattice, the crystal structure under investigation may often have additional point group symmetries. (Web site)

Cell

  1. For each crystal structure there is a conventional unit cell, usually chosen to make the resulting lattice as symmetric as possible.
  2. For each crystal structure there is a conventional unit cell, which is the smallest unit that has the full symmetry of the crystal (see below).
  3. With this definition of the primitive translation vectors, there is no cell of smaller volume that can serve as a building block for the crystal structure.
  4. In the present study, we determined the crystal structure of PFD and compared it with that of FD and three other zymogen–active serine protease pairs. (Web site)

Refinement

  1. The pattern produced gives information of the separations of crystallographic planes d, allowing one to deduce the crystal structure. (Web site)
  2. II. Crystallographic refinement, refined crystal structure and comparison with bovine trypsin.
  3. Crystal structure of bovine trypsinogen at 1-8 A resolution.
  4. Refinement of the crystal structure of a monoclinic ferroan clinochlore. (Web site)
  5. Crystal structure of the complex of porcine trypsin with soybean trypsin inhibitor (Kunitz) at 2.6-A resolution.

Atoms

  1. A crystal structure is composed of a unit cell, a set of atoms arranged in a particular way; which is periodically repeated in three dimensions on a lattice.
  2. The crystal structure consists of the same group of atoms, the basis, positioned around each and every lattice point.
  3. A crystal structure is composed of a motif, a set of atoms arranged in a particular way, and a lattice.
  4. Reconstruction causes the surface atoms to deviate from the bulk crystal structure and arrange in columns several atoms wide with pits between them. (Web site)

Lattice

  1. Along with the unit cell lattice parameters, its space group symbol and the positions of the atoms entirely describe a crystal structure.
  2. The positions of the X-ray beams diffracted by a crystal structure are related to the size and shape of the unit-cell. (Web site)
  3. Isotypic structures crystallize in the same crystal structure and have similar cell parameters and similar atom coordinates.
  4. Enargite crystals In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms in a crystal. (Web site)
  5. The primitive cell is the smallest part of the lattice that which repeated would reconstruct the entire crystal structure. (Web site)

Mineral

  1. In fact, two or more minerals may have the same chemical composition, but differ in crystal structure (these are known as polymorphs).
  2. To be classified as a "true" mineral, a substance must be a solid and have a crystal structure.

Cubic

  1. The diamond cubic crystal structure is a repeating pattern that atoms may adopt as certain materials solidify. (Web site)
  2. The crystal structure, crystal lattice, unit cells, simple cubic metals, close packed structures, and body centred cubic are explored.

Diffraction

  1. In X-ray crystallography, the diffraction pattern of X-rays is used to determine the crystal structure of solids. (Web site)
  2. The crystal structure of 3,5-diisopropyl-4-nitropyrazole from X-ray powder diffraction data. (Web site)
