Yingwei Fei, a high-pressure experimentalist at the Geophysical Laboratory, and Peter Driscoll, a theoretical geophysicist at the Department of Terrestrial Magnetism, have been awarded a Carnegie Science Venture Grant for their project “Direct Shock Compression of Pre-synthesized Mantle Mineral to Super-Earth Interior Conditions.”

Washington, DCPhase transitions surround us—for instance, liquid water changes to ice when frozen and to steam when boiled. Now, researchers at the Geophysical Laboratory have discovered a new phenomenon of so-called metastability in a liquid phase. A metastable liquid is not quite stable. This state is common in supercooled liquids, which are liquids that cool below the freezing point without turning into a solid or a crystal.

Washington, DC—Germanium may not be a household name like silicon, its group-mate on the periodic table, but it has great potential for use in next-generation electronics and energy technology.

Of particular interest are forms of germanium that can be synthesized in the lab under extreme pressure conditions. However, one of the most-promising forms of germanium for practical applications, called ST12, has only been created in tiny sample sizes—too small to definitively confirm its properties.
