Cobalt(II) hydroxideCobalt-60Positronium: This article is about the exotic atom. For the hydrogen isotope, see Protium.Nickel electroplating: Nickel electroplating is a technique of electroplating a thin layer of nickel onto a metal object. The nickel layer can be decorative, provide corrosion resistance, wear resistance, or used to build up worn or undersized parts for salvage purposes.Chromium: Chromium is a chemical element with symbol Cr and atomic number 24. It is the first element in Group 6.Brightray: Brightray is a nickel-chromium alloy that is noted for its resistance to erosion by gas flow at high temperatures. It was used for hard-facing the exhaust valve heads and seats of petrol engines, particularly aircraft engines from the 1930s onwards.Magnesium-protoporphyrin IX monomethyl ester (oxidative) cyclase: Magnesium-protoporphyrin IX monomethyl ester (oxidative) cyclase (, Mg-protoporphyrin IX monomethyl ester (oxidative) cyclase) is an enzyme with system name magnesium-protoporphyrin-IX 13-monomethyl ester,NADPH:oxygen oxidoreductase (hydroxylating) . This enzyme catalyses the following chemical reactionMetals in medicine: Metals in medicine are used in organic systems for diagnostic and treatment purposes. Inorganic elements are also essential for organic life as cofactors in enzymes called Metalloproteins.Phytoextraction process: Phytoextraction is a subprocess of phytoremediation in which plants remove dangerous elements or compounds from soil or water, most usually heavy metals, metals that have a high density and may be toxic to organisms even at relatively low concentrations.http://www.TetraphenylporphyrinVitamin B12-binding domain: In molecular biology, the vitamin B12-binding domain is a protein domain which binds to cobalamin (vitamin B12). It can bind two different forms of the cobalamin cofactor, with cobalt bonded either to a methyl group (methylcobalamin) or to 5'-deoxyadenosine (adenosylcobalamin).Cobalamin biosynthesis: {{Infobox protein familySodium tungstateZinc toxicityCorrin
