    2 Al(CH 3) 3 + 3 H 2 O → Al 2 O 3 + 6 CH 4. H 2 O in the above reaction can be replaced by ozone (O 3) as the active oxidant and the following reaction then takes place: [44] [45] 2 Al(CH 3) 3 + O 3Al 2 O 3 + 3 C 2 H 6. The Al 2 O 3 films prepared using O 3 show 10–100 times lower leakage current density compared with those prepared by ...

    [1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

    Left: The dot-and-cross diagram of the LDQ structure of ozone (O 3). The nuclei are as indicated and the electrons are denoted by either dots or crosses, depending on their relative spins. Right: Simplified diagram of the LDQ structure of O 3, showing electrons in non-coincident pairs using thin lines and a coincident electron pair using a ...

  6. Compatibility diagram - Wikipedia

    en.wikipedia.org/wiki/Compatibility_diagram

    The AKF diagram is intended for rocks containing excess aluminium and silica. Its components are: A = Al 2 O 3 - (CaO + Na 2 O + K 2 O) K = K 2 O F = FeO + MgO + MnO. This diagram is less useful, because magnesium does not freely substitute for ferrous iron in many metamorphic minerals important in aluminium-rich rock.
