  2. Building block (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Building_block_(chemistry)

    Building block is a term in chemistry which is used to describe a virtual molecular fragment or a real chemical compound the molecules of which possess reactive functional groups. [1] Building blocks are used for bottom-up modular assembly of molecular architectures: nano-particles , [ 2 ] [ 3 ] metal-organic frameworks , [ 4 ] organic ...

  3. XYZ file format - Wikipedia

    en.wikipedia.org/wiki/XYZ_file_format

    The XYZ file format is a chemical file format. There is no formal standard and several variations exist, but a typical XYZ format specifies the molecule geometry by giving the number of atoms with Cartesian coordinates that will be read on the first line, a comment on the second, and the lines of atomic coordinates in the following lines.

  4. Heusler compound - Wikipedia

    en.wikipedia.org/wiki/Heusler_compound

    Heusler compounds are magnetic intermetallics with face-centered cubic crystal structure and a composition of XYZ (half-Heuslers) or X 2 YZ (full-Heuslers), where X and Y are transition metals and Z is in the p-block. The term derives from the name of German mining engineer and chemist Friedrich Heusler, who studied such a compound (Cu 2 MnAl ...

  5. Quantum logic gate - Wikipedia

    en.wikipedia.org/wiki/Quantum_logic_gate

    Common quantum logic gates by name (including abbreviation), circuit form(s) and the corresponding unitary matrices. In quantum computing and specifically the quantum circuit model of computation, a quantum logic gate (or simply quantum gate) is a basic quantum circuit operating on a small number of qubits.

  6. Block (periodic table) - Wikipedia

    en.wikipedia.org/wiki/Block_(periodic_table)

    A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. [1] The term seems to have been first used by Charles Janet. [2] Each block is named after its characteristic orbital: s-block, p-block, d-block, f-block and g-block.

  8. Hexagonal ferrite - Wikipedia

    en.wikipedia.org/wiki/Hexagonal_ferrite

    The S block is very common in hexaferrites, which has a chemical formula of Me S 6 O 8 2+. Me S are smaller metal cations, for example, Fe and other transition metals [ 2 ] or noble metals. [ 3 ] The S block is essentially a slab cut along the ( 111 ) {\displaystyle (111)} plane of an AB 2 O 4 spinel.

  9. Autoclaved aerated concrete - Wikipedia

    en.wikipedia.org/wiki/Autoclaved_aerated_concrete

    Accuracy: Panels and blocks made of autoclaved aerated concrete are produced to the exact sizes needed before leaving the factory. There is less need for on-site trimming. Since the blocks and panels fit so well together, there is less use of finishing materials such as mortar.
