Washington, DC— Using laboratory techniques to mimic the conditions found deep inside the Earth, a team of Geophysical Laboratory scientists led by Ho-Kwang “Dave” Mao has identified a form of iron oxide that they believe could explain seismic and geothermal signatures in the deep mantle. Their work is published in Nature.
Washington, DC, 18 March 2016—Geophysical Laboratory team Tim Strobel, Venkat Bhadram, and alum DuckYoung Kim, has discovered a new transition metal, titanium pernitride, TiN2, which is ultraincompressible (bulk modulus ~360-385GPa) and could be a potential superhard material.
Washington, DC—If you freeze any liquid fast enough, even liquid metal, it becomes a glass. Vitrified metals, or metallic glasses, are at the frontier of materials science research.
EFree, a research center at the Geophysical Laboratory, held a Center-wide Neutron Day on December 10, 2015 at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee.
Producing materials by chemical vapor deposition (CVD) has become an important means of synthesis, in which high-energy molecular and atomic species generate a kinetically stable phase trapped in local energy minimum.
Iron makes up most of the Earth's core, which is very hot and exists under extreme pressures.
Washington, DC—Colossal magnetoresistance is a property with practical applications in a wide array of electronic tools including magnetic sensors and magnetic RAM.
Washington, DC—The interiors of several of our Solar System’s planets and moons are icy, and ice has been found on distant extrasolar planets, as well. But these bodies aren’t filled with the regular kind of water ice that you avoid on the sidewalk in winter.
Washington, DC— The matter that makes up distant planets and even-more-distant stars exists under extreme pressure and temperature conditions.
Washington, DC— Superconductivity is a rare physical state in which matter is able to conduct electricity—maintain a flow of electrons—without any resistance.
