Washington, DC—Silicon is the second most-abundant element in the earth's crust. When purified, it takes on a diamond structure, which is essential to modern electronic devices—carbon is to biology as silicon is to technology.
Washington, DC —A key to understanding Earth’s evolution is to look deep into the lower mantle—a region some 400 to 1,800 miles (660 to 2,900 kilometers) below the surface, just above the core.
Washington, DC, 27 October 2014—Compared to its nearest planetary neighbors, Venus and Mars, Earth’s atmosphere is unusually enriched in nitrogen relative to primordial noble gases.
Washington, DC— Hydrogen—the most abundant element in the cosmos—responds to extremes of pressure and temperature differently. Under ambient conditions hydrogen is a gaseous two-atom molecule.
Washington, DC— A team including Carnegie’s Malcolm Guthrie and George Cody has, for the first time, discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymer fibers.
Washington, DC— Gallium arsenide, GaAs, a semiconductor composed of gallium and arsenic is well known to have physical properties that promise practical applications.
Washington, DC — A team of scientists led by Carnegie’s Lin Wang has observed a new form of very hard carbon clusters, which are unusual in their mix of crystalline and disordered structure. The material is capable of indenting diamond.
Washington, DC—Breaking research news from a team of scientists led by Carnegie’s Ho-kwang “Dave” Mao reveals that the composition of the Earth’s lower mantle may be significantly different than previously thought. These results are to be published by Science.
Washington, DC—New research shows that a remarkable defect in synthetic diamond produced by chemical vapor deposition allows researchers to measure, witness, and potentially manipulate electrons in a manner that could lead to new “quantum technology” for information processing.
