2018-10-17 Discovery Compared with other metal elements we discussed about before, Aluminum is discovered much later. In 1808, the British chemist Sir Humphry Davy confirmed the existence of alum and named the substance to Alumium (later changed to Aluminum). In 1825, Danish chemist and physicist Hans Christian Ørsted began experimenting about aluminum extraction.
预计阅读时间：3 分钟Humankind came across aluminium long before the metal we know today was produced. The Natural History by Pliny the Elder, a Roman scientist, told the story of a first century craftsman presenting a cup made of an unknown metal looking like silver, but too light to be sliver, to Tiberius, the Roman Emperor. Alum, an aluminium-based salt, was used extensively in ancient times.
Levothyroxine is a synthetic levoisomer of thyroxine (T4), similar to the endogenous hormone produced by the thyroid gland. Thyroxine is de-iodinated to form triiodothyronine (T3) in the peripheral tissues. T3 enters the cell and binds to nuclear thyroid hormone

Aluminum alloys have been the dominant materials used for airframe structures until the increasing trend in the use of polymer–matrix composites, as shown in Table 4.1 [1,2].The Boeing 787 and Airbus A350 are built with about 50% of these materials, which are lighter than aluminum alloys and possess better resistance to degradation by corrosion and fatigue.
