High Pressure, Planetary Science

Lin Wang is a Carnegie fellow at the Geophysical Laboratory.  He is working with Yingwei Fei on the connectivity of iron sulfide liquid in a Bridgemanite matrix.  Wang is also interested in the rheology of Earth's materials and high pressure generation.  Prior to the Geophysical Laboratory, Wang

The Geophysical Laboratory's weekly seminar series continues with Allen McNamara of Michigan State University. He will present, "Large Low Shear Velocity Provinces in the Lower Mantle."

High Pressure, Matter at Extreme States

Lab-based mimicry allowed an international team of physicists including the Geophysical Laboratory’s Alexander Goncharov to probe hydrogen under the conditions found in the interiors of giant planets—where experts believe it gets squeezed until it becomes a liquid metal, capable of conducting electricity. Their work is published in Science.

Irina Chuvashova joins the Geophysical Laboratory as a postdoctoral associate, previously from LSPM-CNRS Universite Paris Nord.  She is working with Alex Goncharov on high-pressure investigations of transport and elastic properties of the Earth's minerals.  Additionally, she is interested in sintering materials with different defined properties using various methods, especially high pressure and analytical techniques.

High Pressure, Materials, Matter at Extreme States

New work from a team led by the Geophysical Laboratory’s Alexander Goncharov confirms that nitrogen, the dominant gas in Earth’s atmosphere, becomes a metallic fluid when subjected to the extreme pressure and temperature conditions found deep inside the Earth and other planets. Their findings are published by Nature Communications.
