Perhaps the most important consideration is a coating for the magnet, as typical neodymium disk magnets are not suitable for implantation. Magnets must be coated in an inert and biosafe material, so the body does not attack the magnet. Popular magnet coatings include implant grade silicone, parylene, titanium nitride, gold and rhodium. Disc ...
Rhodium is a hard, silvery, durable metal that has a high reflectance. Rhodium metal does not normally form an oxide, even when heated. [25] Oxygen is absorbed from the atmosphere only at the melting point of rhodium, but is released on solidification. [26] Rhodium has both a higher melting point and lower density than platinum.
Iron is a part of some hormones as well. A lack of iron in the body can cause iron deficiency anemia, and an excess of iron in the body can be toxic. [7] Some ruthenium-containing molecules may be used to fight cancer. [8] Normally, however, ruthenium plays no role in the human body. [3] Both osmium and hassium have no known biological roles ...
Toxic in some forms; the sodium salt is fatal to humans in small doses, and the oxide causes severe bad breath. [11] terbium: 65: 2a: Has no known biological role, but is probably similar to other lanthanides such as cerium and lanthanum, i.e., not known to be essential. [11] Terbium is also one of the rarer lanthanides. Toxic in some forms ...

Many kinds of fish are rich in iodine and other nutrients your body needs to make and use thyroid hormone efficiently. Best bets: Cod, tuna, seaweed, shrimp and other shellfish are excellent ...
Organorhodium chemistry is the chemistry of organometallic compounds containing a rhodium-carbon chemical bond, and the study of rhodium and rhodium compounds as catalysts in organic reactions. [ 1 ] Stable organorhodium compounds and transient organorhodium intermediates are used as catalyst such as in olefin hydroformylation , olefin ...
