High Pressure

Washington, DC — How hydrogen--the most abundant element in the cosmos--responds to extremes of pressure and temperature is one of the major challenges in modern physical science.

Geochemistry, High Pressure

Washington, DC, 28 March 2012- A Carnegie scientists' observations have led the way to stabilizing tungsten hydrides under high pressure.

High Pressure, Materials

Washington, DC — Superconductivity is a rare physical state in which matter is able to conduct electricity—maintain a flow of electrons—without any resistance.

High Pressure

Washington, DC, 21 February 2012- In a combined experimental effort researchers from the Geophysical Laboratory, Oak Ridge National Laboratory and Steacie Institute for Molecular Sciences now have a better understanding of a form of high pressure methane clathrate hydrate.

High Pressure, Materials

Washington, DC—The crushing pressures and intense temperatures in Earth’s deep interior squeeze atoms and electrons so closely together that they interact very differently. With depth materials change.

High Pressure, Materials

Washington, DC,16 December 2011- Carnegie scientists have discovered a new compound composed of H2S and H2. The results further elucidate the role of pressure on intermolecular interactions in molecular compounds.

High Pressure

Washington, DC — The composition of the Earth’s core remains a mystery. Scientists know that the liquid outer core consists mainly of iron, but it is believed that small amounts of some other elements are present as well.

High Pressure, Materials

Washington, DC — Carbon is the fourth-most-abundant element in the universe and takes on a wide variety of forms, called allotropes, including diamond and graphite.

High Pressure

Washington, DC, 15 September 2011- A new study including Wenge Yang from Carnegie reveals a new phase of high energy Aluminum produced using an ultrafast laser induced confined micro-explosion inside a sapphire.

High Pressure, Materials

Washington, DC—Glasses differ from crystals. Crystals are organized in repeating patterns that extend in every direction. Glasses lack this strict organization, but do sometimes demonstrate order among neighboring atoms.
