Washington, DC—New work from a research team led by the Geophysical Laboratory's Anat Shahar contains some unexpected findings about iron chemistry under high-pressure conditions, such as those likely found in the Earth’s core, where iron predominates and creates our planet’s life-shielding magnetic field.
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— A team of scientists including Carnegie’s Dina Bower and Andrew Steele weigh in on whether microstructures found in 3.46 billion-year-old samples of a silica-rich rock called chert found in Western Australia are the planet’s oldest fossils.
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.
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—New research from a team led by Carnegie’s Robert Hazen predicts that Earth has more than 1,500 undiscovered minerals and that the exact mineral diversity of our planet is unique and could not be duplicated anywhere in the cosmos.
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.
