High Pressure, Materials, 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.

High Pressure, Matter at Extreme States, Planetary Science

The properties of hydrogen at extreme pressures and temperatures are of great interest to condensed matter physics, astrophysics, and planetary science due to the element’s putative

High Pressure, Materials, Matter at Extreme States

Our science cannot be accomplished without state-of-the-art instruments. But sometimes the existing tools simply aren’t enough.

High Pressure, Materials, Matter at Extreme States

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.
