  2. Biological functions of nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Biological_functions_of...

    Biological functions of nitric oxide are roles that nitric oxide plays within biology. Nitric oxide (nitrogen monoxide) is a molecule and chemical compound with chemical formula of N O . In mammals including humans, nitric oxide is a signaling molecule involved in several physiological and pathological processes. [ 1 ]

  3. Magnesium oxide - Wikipedia

    en.wikipedia.org/wiki/Magnesium_oxide

    Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding .

  4. Stannosis - Wikipedia

    en.wikipedia.org/wiki/Stannosis

    A variety of tin alloys morphologies exist including the following metals: soft solder, fusible, pewter, bronze, Babbit, White, and phosphor bronze metal. [9] Tin oxide metals are corrosive resistant which is important in industrial uses. [9] Tin(II) oxide, or Stannous oxide, is a brown-black powder or blue-black crystalline solid compound.

    Traditionally used in medicine and dental fillings, it is now avoided due to toxic side effects. [11] Can inactivate certain enzymes, as a result, both the metal and some compounds (especially methylmercury) are harmful to most life forms; there is a long and complex history of mercury poisoning in humans. [11] molybdenum: 42: 5

  6. Electro-oxidation - Wikipedia

    en.wikipedia.org/wiki/Electro-oxidation

    Simple scheme of the apparatus for electro-oxidation process. The set-up for performing an electro-oxidation treatment consists of an electrochemical cell.An external electric potential difference (aka voltage) is applied to the electrodes, resulting in the formation of reactive species, namely hydroxyl radicals, in the proximity of the electrode surface. [11]

  7. Copper(I) oxide - Wikipedia

    en.wikipedia.org/wiki/Copper(I)_oxide

    Copper(I) oxide may be produced by several methods. [3] Most straightforwardly, it arises via the oxidation of copper metal: 4 Cu + O 2 → 2 Cu 2 O. Additives such as water and acids affect the rate as well as the further oxidation to copper(II) oxides. It is also produced commercially by reduction of copper(II) solutions with sulfur dioxide.

  8. Flux (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Flux_(metallurgy)

    The general reaction of oxide removal is: Metal oxide + Acid → Salt + Water. Salts are ionic in nature and can cause problems from metallic leaching or dendrite growth, with possible product failure. In some cases, particularly in high-reliability applications, flux residues must be removed.

  9. Biometal (biology) - Wikipedia

    Sodium is a metal where humans have discovered a great deal of its total roles in the body as well as being one of the only two alkali metals that play a major role in the bodily functions. It plays an important role in maintenance of the cell membrane potential and the electrochemical gradient in the body via the sodium-potassium pump and ...
