  2. Cubic crystal system - Wikipedia

    en.wikipedia.org/wiki/Cubic_crystal_system

    This structure is often confused for a body-centered cubic structure because the arrangement of atoms is the same. However, the caesium chloride structure has a basis composed of two different atomic species. In a body-centered cubic structure, there would be translational symmetry along the [111] direction.

  3. Crystal structure - Wikipedia

    en.wikipedia.org/wiki/Crystal_structure

    This type of structural arrangement is known as cubic close packing (ccp). The unit cell of a ccp arrangement of atoms is the face-centered cubic (fcc) unit cell. This is not immediately obvious as the closely packed layers are parallel to the {111} planes of the fcc unit cell. There are four different orientations of the close-packed layers.

  4. Supercell (crystal) - Wikipedia

    en.wikipedia.org/wiki/Supercell_(crystal)

    Some different supercells for 2D cubic crystal. Both diagonal and non-diagonal supercells presented. In solid-state physics and crystallography, a crystal structure is described by a unit cell repeating periodically over space. There are an infinite number of choices for unit cells, with different shapes and sizes, which can describe the same ...

  6. Unit cell - Wikipedia

    en.wikipedia.org/wiki/Unit_cell

    A primitive cell is a unit cell that contains exactly one lattice point. For unit cells generally, lattice points that are shared by n cells are counted as ⁠ 1 / n ⁠ of the lattice points contained in each of those cells; so for example a primitive unit cell in three dimensions which has lattice points only at its eight vertices is considered to contain ⁠ 1 / 8 ⁠ of each of them.

  8. Manganese - Wikipedia

    en.wikipedia.org/wiki/Manganese

    It has a body-centered cubic lattice and is unusual among elemental metals in having a very complex unit cell, with 58 atoms per cell (29 atoms per primitive unit cell) in four different types of site. [21] [18] It is paramagnetic at room temperature and antiferromagnetic at temperatures below 95 K (−178 °C). [22] Phase diagram of manganese [18]

  9. Resolution (structural biology) - Wikipedia

    en.wikipedia.org/.../Resolution_(structural_biology)

    In structural biology, resolution can be broken down into 4 groups: (1) sub-atomic, when information about the electron density is obtained and quantum effects can be studied, (2) atomic, individual atoms are visible and an accurate three-dimensional model can be constructed, (3) helical, secondary structure, such as alpha helices and beta sheets; RNA helices (in ribosomes), (4) domain, no ...
