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.

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.
