Modern uses of lanthanum include: LaB 6 hot cathode. One material used for anodic material of nickel–metal hydride batteries is La(Ni 3.6 Mn 0.4 Al 0.3 Co 0.7). Due to high cost to extract the other lanthanides, a mischmetal with more than 50% of lanthanum is used instead of pure lanthanum.
‘Land of the free, and home of the medical bankruptcy’: Ex–surgeon general blasts health care system after getting $4,896.43 bill for dehydration. Chloe Berger. March 1, 2024 at 4:24 PM.
Lanthanum(III) oxide, also known as lanthana, chemical formula La 2 O 3, is an inorganic compound containing the rare earth element lanthanum and oxygen. It is used in some ferroelectric materials, as a component of optical materials, and is a feedstock for certain catalysts, among other uses.
Lanthanum carbonate is used in medicine as a phosphate binder. [1] As a medication it is sold under the trade name Fosrenol by the pharmaceutical company Shire Pharmaceuticals. Due to its large size (1000 mg tablet is 2.2 cm in diameter), it may be possible to choke on the tablet if it is not chewed.
Lanthanum chloride is also used in biochemical research to block the activity of divalent cation channels, mainly calcium channels. Doped with cerium, it is used as a scintillator material. [6] In organic synthesis, lanthanum trichloride functions as a mild Lewis acid for converting aldehydes to acetals. [7]
A former U.S. surgeon general has slammed the nation’s health-care system after he was billed nearly $5,000 — after insurance — for a quick trip to an emergency room (ER) while suffering ...
payments to physicians increase health care costs and may result in unfair competition. When a device manufacturer pays a physician to influence the physician’s use or recommendation of its products, rather than to advance a legitimate medical interest, the additional costs are passed on to the patients, Federal health care programs, and private
Lanthanum nitride can be prepared from the reaction of nitrogen and lanthanum trihydride: 2LaH 3 + N 2 → 2LaN + 3H 2. It can also be prepared from the reaction of ammonia and lanthanum trihydride: [3] LaH 3 + NH 3 → LaN + 3H 2. The reaction of nitrogen and lanthanum amalgam can also work: [4] 2La + N 2 → 2LaN
