About the Geophysical Laboratory

The Geophysical Laboratory was established in 1905 to investigate the processes that control the composition and structure of the Earth as it was known at the time, including developing the underlying physics and chemistry and creating the experimental tools required for the task. Over a century later, this core mission has expanded to include the physics, chemistry, and biology of the Earth over the entire range of conditions our planet has experienced since its formation, as well as parallel studies of other planets of this and other solar systems from their surfaces to their cores.

Materials

Washington, DC— A team including several Geophysical Laboratory scientists has developed a form of ultrastrong, lightweight carbon that is also elastic and electrically conductive. A material with such a unique combination of properties could serve a wide variety of applications from aerospace engineering to military armor.

Carbon is an element of seemingly infinite possibilities. This is because the configuration of its electrons allows for numerous self-bonding combinations that give rise to a range of materials with varying properties. For example, transparent, superhard diamonds, and opaque graphite, which is used for both pencils and industrial lubricant, are comprised solely of carbon.

Materials

Washington, DC—It would be difficult to overestimate the importance of silicon when it comes to computing, solar energy, and other technological applications. (Not to mention the fact that it makes up an awful lot of the Earth’s crust.) Yet there is still so much to learn about how to harness the capabilities of element number 14.

High Pressure

Washington, DC— New work from a team including the Geophysical Laboratory's Guoyin Shen and Yoshio Kono used high pressure and temperature to reveal a kind of “structural memory” in samples of the metal bismuth, a discovery with great electrical engineering potential.

Department

On Tuesday, 9 May 2017, the Geophysical Laboratory and DTM employees gathered at the Greenewalt buildilng to present recent results to one another using posters and demonstrations for the Third Annual Broad Branch Road Poster Session!

Geochemistry

The Fellowship was awarded, "For outstanding contributions to experimental petrology especially to the structures, properties, and elemental partitioning behavior of magmas and fluids at high pressure and temperature, and also for his continuing initiatives to activate the Japanese Geoscience Union and its International Journal, Progress in Earth and Planetary Science (PEPS)”.
