High Pressure

Washington, DC—Using revolutionary new techniques, a team led by Carnegie’s Malcolm Guthrie has made a striking discovery about how ice behaves under pressure, changing ideas that date back almost 50 years.

High Pressure, Materials

Washington, DC—Hydrogen is the most abundant element in the universe. The way it responds under extreme pressures and temperatures is crucial to our understanding of matter and the nature of hydrogen-rich planets.

 

High Pressure

Washington, DC— A team of researchers has made a major breakthrough in measuring the structure of nanomaterials under extremely high pressures.

High Pressure, Materials

Washington, DC, 21 December 2012 — Researchers from the Geophysical Laboratory have observed a new compound form of sodium and silicon - a "covalent metal," with unusual structural and electrical properties.

High Pressure

Washington, DC — When materials are stressed, they eventually change shape. Initially these changes are elastic, and reverse when the stress is relieved. When the material’s strength is exceeded, the changes become permanent.

High Pressure, Planetary Science

Washington, DC— The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors.

Geochemistry, High Pressure, Materials

Washington, DC, 26 November 2012 -- The Geophysical Laboratory’s Stewart McWilliams and his team find evidence that alters our understanding of planetary evolution.

High Pressure, Materials

Washington, DC—Carnegie scientists are the first to discover the conditions under which nickel oxide can turn into an electricity-conducting metal.

High Pressure, Materials

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.

High Pressure

Washington, DC, 4 May 2012- A collaborative experimental effort with Carnegie researchers has discovered unknown properties of a computer memory material that will allow for faster data transfer with a higher capacity of data stored.
