Aberdeen vs Cobalt

Informations

Aberdeen ( (listen); Scots: Aiberdeen, listen ; Scottish Gaelic: Obar Dheathain [opəɾ ˈɛ.ɛɲ]; Latin: Aberdonia) is a city in northeast Scotland. It is Scotland's third most populous city, one of Scotland's 32 local government council areas (as Aberdeen City) and the United Kingdom's 39th most populous built-up area, with an official 2018 population estimate of 198,880 for the city of Aberdeen and 227,560 for the local council area.During the mid-18th to mid-20th centuries, Aberdeen's buildings incorporated locally quarried grey granite, which can sparkle like silver because of its high mica content. Since the discovery of North Sea oil in the 1970s, Aberdeen has been known as the off-shore oil capital of Europe. The area around Aberdeen has been settled for at least 8,000 years, when prehistoric villages lay around the mouths of the rivers Dee and Don. The city has a long, sandy coastline and a marine climate, the latter resulting in chilly summers and mild winters. Aberdeen received Royal burgh status from David I of Scotland (1124–1153), transforming the city economically. The city has two universities, the University of Aberdeen, founded in 1495, and Robert Gordon University, which was awarded university status in 1992, making Aberdeen the educational centre of north-east Scotland.

The traditional industries of fishing, paper-making, shipbuilding, and textiles have been overtaken by the oil industry and Aberdeen's seaport. Aberdeen Heliport is one of the busiest commercial heliports in the world and the seaport is the largest in the north-east of Scotland.Aberdeen used to host the Aberdeen International Youth Festival, a major international event which attracted up to 1000 of the most talented young performing arts companies but the council ended funding in 2017 and the festival was wound up in 2018. In 2015, Mercer named Aberdeen the 57th most liveable city in the world, as well as the fourth most liveable city in Britain. In 2012, HSBC named Aberdeen as a leading business hub and one of eight 'super cities' spearheading the UK's economy, marking it as the only city in Scotland to receive this accolade. In 2018, Aberdeen was found to be the best city in the UK to start a business in a study released by card payment firm Paymentsense.

Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments (cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was later thought to be due to the known metal bismuth. Miners had long used the name kobold ore (German for goblin ore) for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the kobold. Today, some cobalt is produced specifically from one of a number of metallic-lustered ores, such as cobaltite (CoAsS). The element is, however, more usually produced as a by-product of copper and nickel mining.

The copper belt in the Democratic Republic of the Congo (DRC) and Zambia yields most of the global cobalt production. World production in 2016 was 116,000 metric tons (114,000 long tons; 128,000 short tons) (according to Natural Resources Canada), and the DRC alone accounted for more than 50%.Cobalt is primarily used in lithium-ion batteries, and in the manufacture of magnetic, wear-resistant and high-strength alloys. The compounds cobalt silicate and cobalt(II) aluminate (CoAl2O4, cobalt blue) give a distinctive deep blue color to glass, ceramics, inks, paints and varnishes. Cobalt occurs naturally as only one stable isotope, cobalt-59. Cobalt-60 is a commercially important radioisotope, used as a radioactive tracer and for the production of high-energy gamma rays. Cobalt is the active center of a group of coenzymes called cobalamins. Vitamin B12, the best-known example of the type, is an essential vitamin for all animals. Cobalt in inorganic form is also a micronutrient for bacteria, algae, and fungi.
