A piece of cuprate of bismuth and strontium: this piece is a cube with an edge of nearly 1 mm. Bismuth strontium calcium copper oxide (BSCCO, pronounced bisko), is a type of cuprate superconductor having the generalized chemical formula Bi 2 Sr 2 Ca n−1 Cu n O 2n+4+x, with n = 2 being the most commonly studied compound (though n = 1 and n = 3 have also received significant attention).
The European Union – Latin America and Caribbean Foundation (EU–LAC Foundation) is an international organisation created in 2010 by the Heads of State and Government of the European Union (EU), Latin America and Caribbean (LAC) with the mission of strengthening and promoting the strategic partnership between both regions, improving its visibility and encouraging the participation of the ...

[2] The FCO was itself created in 1968 by the merger of the Foreign Office (FO) and the Commonwealth Office. The department in its various forms is responsible for representing and ...
18, which is prepared by reducing a mixture of hafnium(IV) chloride and bismuth chloride with elemental bismuth, having the structure [Bi +] [Bi 5+ 9] [HfCl 2− 6] 3. [5]: 50 Other polyatomic bismuth cations are also known, such as Bi 2+ 8, found in Bi 8 (AlCl 4) 2. [11] There is a true monoiodide, BiI, which contains chains of Bi 4 I 4 units.
At the start of the 19th century, the foreign secretary would have had one or two private secretaries, who were often personal appointments of the office-holder.As the complexity of British foreign policy grew significantly, and consequently the size of the private office expanded to provide policy and administrative support; the chief civil servant in the private office became the principal ...
Besides 209 Bi, the most stable bismuth radioisotopes are 210m Bi with a half-life of 3.04 million years, 208 Bi with a half-life of 368,000 years and 207 Bi, with a half-life of 32.9 years, none of which occurs in nature. All other isotopes have half-lives under 1 year, most under a day.
