High Pressure, Materials

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.

High Pressure

Washington, DC— Earth's magnetic field shields us from deadly cosmic radiation, and without it, life as we know it could not exist here. The motion of liquid iron in the planet’s outer core, a phenomenon called a “geodynamo,” generates the field.

Reinhard (Reini) Boehler works on a broad range of problems in high pressure science and technology, particularly those related to major energy challenges.

Venkata (Venkat) Bhadram is working with Tim Strobel on EFree projects, mainly in the area of solar energy materials. He is also working on developing novel materials for photocatalytic water splitting.

Geochemistry, High Pressure, Matter at Extreme States

Neil Bennett is a postdoctoral fellow at the Geophysical Laboratory, who hails from the University of Toronto. He is working working with Anat Shahar and Yingwei Fei to conduct piston cylinder experiments on the iron isotope fractionation between olivine and metal.

Abhisek Basu joins the Geophysical Laboratory as a postdoctoral associate working with Reinhard Boehler. He is working on developing large volume diamond cells for neutron diffraction and is also interested in high pressure behavior of perovskite oxides using XRD and Raman spectroscopy.

Muhetaer Aihaiti (Muhtar Ahart) runs the Brillouin Spectroscopy Laboratory at the Geophysical Laboratory. His research in high-pressure physics is aimed largely at problems in ferroelectrics, relaxor ferroelectrics, polymers, and novel materials.

High Pressure, Materials, Planetary Science

Ronald E. Cohen's primary focus is the study of materials through first principles research including properties of materials under extreme conditions such as high pressure and temperature. His research is applied to topics and problems in geophysics and technological materials.

Geochemistry, High Pressure

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.

High Pressure

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.
