Geochemistry, High Pressure, Matter at Extreme States

Michael Walter is the Director of the Geophysical Laboratory. Walter’s research focuses on the differentiation of the mantle and core, mantle melting and element partitioning, subsolidus phase relations and crystal chemistry, and the origin of deep mantle diamonds and their inclusions.

High Pressure, Materials, Matter at Extreme States

The Geophysical Laboratory’s Tim Strobel and Venkata Bhadram now report unexpected quantum behavior of hydrogen molecules, H2, trapped within tiny cages made of organic molecules, demonstrating that the structure of the cage influences the behavior of the molecule imprisoned inside it.

Matter at Extreme States

The Geophysical Laboratory's weekly seminar series continues with Stewart McWilliams of the University of Edinburgh. He will present, "Dynamic probes of structure and transport at extreme conditions."

The paradox of the missing xenon might sound like the title of the latest airport thriller, but it’s actually a problem that’s stumped geophysicists for decades. New work from an international team including the Geophysical Laboratory’s Alexander Goncharov and Hanyu Liu, and GL alumni Elissaios Stavrou and Sergey Lobanov, is chasing down the solution to this longstanding puzzle.

High Pressure, Materials, Matter at Extreme States

New work from the Geophysical Laboratory's high-pressure geophysicists Chuanlong Lin, Jesse Smith, Stanislav Sinogeikin, and Guoyin Shen found evidence of the long-theorized, difficult-to-see low-density liquid phase of water.

High Pressure, Matter at Extreme States, Planetary Science

Washington, DC — Plumes of hot rock surging upward from the Earth’s mantle at volcanic hotspots contain evidence that the Earth’s formative years may have been even more chaotic than previously thought, according to new work from the Geophysical Laboratory's Yingwei Fei and Colin Jackson published in Nature.

High Pressure, Materials, Matter at Extreme States

A team of experimental and computational scientists led by the Geophysical Laboratory’s Tim Strobel and Venkata Bhadram have synthesized a long sought-after form of titanium nitride, Ti3N4, which has promising mechanical and optoelectronic properties.
