Naturally occurring terbium (65 Tb) is composed of one stable isotope, 159 Tb. Thirty-seven radioisotopes have been characterized, with the most stable being 158 Tb with a half-life of 180 years, 157 Tb with a half-life of 71 years, and 160 Tb with a half-life of 72.3 days.
Terbium is a chemical element; it has the symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is malleable and ductile . The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas.
The U.S. Citizenship and Immigration Services has an additional TB classification for immigrants and refugees developed by the Centers for Disease Control and Prevention (CDC). [3] The B notification program is an important screening strategy to identify new arrivals who have a high risk for TB.
Terfenol-D is an alloy of terbium, iron and dysprosium, with the formula of Tb x Dy 1−x Fe 2. It was initially developed in the 1970s by the Naval Ordnance Laboratory in the United States. The technology for manufacturing the material efficiently was developed in the 1980s at Ames Laboratory under a U.S. Navy-funded program. [ 69 ]
A Stellantis joint venture with Samsung SDI has won a commitment from the U.S. government for up to a $7.54 billion loan to help build two electric vehicle battery plants in Kokomo, Indiana. The ...
Last week, the U.S. Chamber of Commerce informed members in an email that the Biden administration was considering adding as many as 200 Chinese chip companies to a trade blacklist, which would ...
Terbium(III) oxide, also known as terbium sesquioxide, is a sesquioxide of the rare earth metal terbium, having chemical formula Tb 2 O 3. It is a p-type semiconductor, which conducts protons, which is enhanced when doped with calcium. [3] It may be prepared by the reduction of Tb 4 O 7 in hydrogen at 1300 °C for 24 hours. [4] Tb 4 O 7 + H 2 ...
