Manganese
Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron.
Manganese nodule
Polymetallic nodules, also called manganese nodules, are rock concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core. As nodules can be found in vast quantities, and contain valuable metals, deposits have been identified as having economic interest.
Manganese dioxide
Manganese oxide is the inorganic compound with the formula MnO2. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules.
Manganese Bronze Holdings
Manganese Bronze Holdings plc was the holding company of LTI Limited. The firm's sole business in its final years as a company was London black taxicab manufacturing through the LTI subsidiary.
Manganese(II) chloride
Manganese chloride is the dichloride salt of manganese, MnCl2. This inorganic chemical exists in the anhydrous form, as well as the dihydrate (MnCl2·2H2O) and tetrahydrate (MnCl2·4H2O), with the tetrahydrate being the most common form.
Manganese(II) sulfate
Manganese sulfate usually refers to the inorganic compound with the formula MnSO4·H2O. This pale pink deliquescent solid is a commercially significant manganese(II) salt. Approximately 260,000 tonnes of manganese(II) sulfate were produced worldwide in 2005.
Manganese(IV) fluoride
Manganese tetrafluoride, MnF4, is the highest fluoride of manganese. It is a powerful oxidizing agent and is used as a means of purifying elemental fluorine.
Manganese peroxidase
In enzymology, a manganese peroxidase is an enzyme that catalyzes the chemical reaction 2 Mn(II) + 2 H+ + H2O2 ⇌ {\displaystyle \rightleftharpoons } 2 Mn(III) + 2 H2OThe 3 substrates of this enzyme are Mn(II), H+, and H2O2, whereas its two products are Mn(III) and H2O. This enzyme belongs to the family of oxidoreductases, to be specific those acting on a peroxide as acceptor (peroxidases). The systematic name of this enzyme class is Mn(II):hydrogen-peroxide oxidoreductase.
Manganese(II,III) oxide
Manganese oxide is the chemical compound with formula Mn3O4. Manganese is present in two oxidation states +2 and +3 and the formula is sometimes written as MnO·Mn2O3.
Manganese, Minnesota
Manganese is a ghost town and former mining community in the U.S. state of Minnesota that was inhabited between 1912 and 1960. It was built in Crow Wing County on the Cuyuna Iron Range in sections 23 and 28 of Wolford Township, about 2 miles north of Trommald, Minnesota.
Montebelluna
Montebelluna is a city and comune in Veneto, Italy, approximately 50 kilometres northwest of Venice. It has an estimated population of 32,000.Fila has research and development facilities in Montebelluna.
