Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

Africa is splitting in two – here is why

Why Does Rifting Happen?Breaking Up Isn’T EasyA Timeline in ActionWhen the lithosphere is subject to a horizontal extensional force it will stretch, becoming thinner. Eventually, it will rupture, leading to the formation of a rift valley. This process is accompanied by surface manifestations along the rift valley in the form of volcanism and seismic activity. Rifts are the initial stage of a continental break-up and, if successful, can lead to the formation of a new ocean basin. An example of a place on Earth where this has happened is the South Atlantic ocean, which resulted from the break up of South America and Africa around 138m years ago– ever noticed how their coastlines match like pieces of the same puzzle?. Continental rifting requires the existence of extensional forces great enough to break the lithosphere. The East African Rift is described as an active type of rift, in which the source of these stresses lies in the circulation of the underlying mantle. Beneath this rift, the rise of a large mantle plume is doming the lithosphere upward...Get price

HistoryOperationsSelectionOperatorBadgeFurther ReadingExternal LinksThe first South African Special Forces unit, 1 Reconnaissance Commando, was established in the town of Oudtshoorn, Cape Province on 1 October 1972. On 1 January 1975, this unit was relocated to Durban, Natal,where it continued its activities as the airborne specialist unit of the special forces. Later, two additional Reconnaissance Commandos were formed: 1. 4 Reconnaissance Commando, specialising in seaborne operations, was established in the coastal town of Langebaan, Cape Province. 2. 5 Reconnaissance Commando was established at the Duku-Duku camp in Natal, but was later moved to Phalaborwain the Transvaal province. On 1 January 1981, a re-organisation of Special Forces took place, as part of which the Reconnaissance Commandos and other special forces were transformed into an independent formation, directly under the command of the (then) South African Defence Force (instead of the South African Army).
