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.

Matter at Extreme States

Washington, DC— A team of Geophysical Laboratory high-pressure physicists have created a form of carbon that’s hard as diamond, but amorphous, meaning it lacks the large-scale structural repetition of a diamond’s crystalline structure. Their findings are reported in Nature Communications.

GL alum Sergey Lobanov received official confirmation from the Helmholtz Association this week that he has won the competition for the Helmholtz Young Investigator Group Leaders award. This means that he will receive 1.8 million Euro for 2018-2023 to establish a new group at GFZ (Potsdam, Germany). His group will be part of a larger group of Dr. Monika Koch-Müller and will collaborate closely with other scientists at GFZ and throughout the Helmholtz Association. Lobanov's group will focus on characterizing key unknown properties of the deep Earth as well as exploring their geophysical significance.

High Pressure

Washington, DC  A group of scientists led by the Geophysical Laboratory's Huiyang Gou and Timothy Strobel performed high-pressure experiments on linear dicyanoacetylene (C4N2) using a diamond anvil cell, in which a pressure-induced reaction process was uncovered. Discrete linear C4N2 molecules were found to polymerize into a disordered extended network without significant change to the bulk composition.
