Transparent aluminium is 'new state of matter'

(PhysOrg.com) -- Oxford scientists have created a transparent form of aluminium by bombarding the metal with the world’s most powerful soft X-ray laser. 'Transparent aluminium' previously only existed in science fiction, ...

Were Twin Towers felled by chemical blasts? (Update)

A mix of sprinkling system water and melted aluminium from aircraft hulls likely triggered the explosions that felled New York's Twin Towers on September 11, 2001, a materials expert has told a technology conference.

Astronomers see unexpected molecule in exoplanet atmosphere

SRON-astronomers have found the signature for aluminum oxide (AlO) in the spectrum of exoplanet WASP-43b. This came as a surprise because AlO is expected to stay hidden in the lower atmospheric layers. It is only the second ...

Micro-explosion reveals new super-dense aluminium

(PhysOrg.com) -- Although materials scientists have theorized for years that a form of super-dense aluminum exists under the extreme pressures found inside a planet’s core, no one had ever actually seen it. Until now.

Seeds from the Moringa tree can be used for water purification

Pure water is a key requirement for good health and alternative cheap, safe methods are required in many countries. In a paper that has just been published in the leading American Chemical Society journal on interfaces, Langmuir, ...

Aluminium

US i/əˈluːmɨnəm/ ə-loo-mi-nəm

Aluminium or aluminum (US English) is a silvery white member of the boron group of chemical elements. It has the symbol Al, and its atomic number is 13. It is not soluble in water under normal circumstances. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal, in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface. Aluminium metal is too reactive chemically to occur natively. Instead, it is found combined in over 270 different minerals. The chief ore of aluminium is bauxite.

Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.

Despite its prevalence in the environment, aluminium salts are not known to be used by any form of life. In keeping with its pervasiveness, it is well tolerated by plants and animals. Because of their prevalence, potential biological roles, beneficial and otherwise, aluminium compounds are of continuing interest.
