Washington, DC— A long-sought-after class of “superdiamond” carbon-based materials with tunable mechanical and electronic properties was predicted and synthesized by Carnegie’s Li Zhu and Timothy Strobel.

High Pressure

Washington, DC— Every school child learns about the water cycle—evaporation, condensation, precipitation, and collection.

High Pressure

Washington, DC— Pressure improves the ability of materials to turn heat into electricity and could potentially be used to create clean generators, according to new work from a team that includes Carnegie’s Alexander Goncharov and Viktor Struzhkin published in 

Matter at Extreme States

New materials can contribute potential solutions to many societal issues—from increasing access to clean drinking water to improving solar panel efficiency.

Lab-based mimicry allowed an international team of physicists including the Geophysical Laboratory’s Alexander Goncharov to probe hydrogen under the conditions found in the interiors of giant planets—where experts believe it gets squeezed until it becomes a liquid metal, capable of conducting electricity. Their work is published in Science.

Blue diamonds—like the world-famous Hope Diamond at the National Museum of Natural History—formed up to four times deeper in the Earth’s mantle than most other diamonds, according to new work by Carnegie’s Steven Shirey, Emma Bullock, and Jianhua Wang and published on the cover of Nature.
