Science Highlights

Washington, D.C., 14 April 2015— The cores of terrestrial planets and satellite bodies, including the Moon, all contain large quantities of iron.  New work from the Geophysical Laboratory's Yingwei Fei provides new measurements of iron at lunar core conditions that will help build a direct compositional and velocity model of the Moon’s core in conjunction with limited lunar seismic data.

Washington, D.C., 20 March 2015— A team led by Geophysical Laboratory scientists was able to discover five new forms of silica under extreme pressures at room temperature.

Washington, D.C.—A team of scientists, including the Geophysical Laboratory's Zhenxian Liu, report experimental evidence for tetrahedrally coordinated carbon in high pressure carbonates. This bonding behavior could have significant implications for carbon reservoirs and fluxes, as well as for understanding the global geodynamic carbon cycle.

Washington. D.C.—The Geophysical Laboratory's Guoyin Shen and Zhisheng Zhao, have found that the hybrid Type II glass-like carbon possesses many advantageous properties, such as high strength, high volume compression, superelastic recovery from large volume deformation, and more.
