Washington, DC—The crushing pressures and intense temperatures in Earth’s deep interior squeeze atoms and electrons so closely together that they interact very differently. With depth materials change.
Washington, DC,16 December 2011- Carnegie scientists have discovered a new compound composed of H2S and H2. The results further elucidate the role of pressure on intermolecular interactions in molecular compounds.
Washington, DC — The composition of the Earth’s core remains a mystery. Scientists know that the liquid outer core consists mainly of iron, but it is believed that small amounts of some other elements are present as well.
Washington, DC — Carbon is the fourth-most-abundant element in the universe and takes on a wide variety of forms, called allotropes, including diamond and graphite.
Washington, DC, 15 September 2011- A new study including Wenge Yang from Carnegie reveals a new phase of high energy Aluminum produced using an ultrafast laser induced confined micro-explosion inside a sapphire.
Washington, DC—Meteorites hold a record of the chemicals that existed in the early Solar System and that may have been a crucial source of the organic compounds that gave rise to life on Earth.
Washington, DC—Glasses differ from crystals. Crystals are organized in repeating patterns that extend in every direction. Glasses lack this strict organization, but do sometimes demonstrate order among neighboring atoms.
Washington, DC— Scientists have long debated about the origin of carbon in Earth’s oldest sedimentary rocks and how it might signal the remnants of the earliest forms of life on the planet.
Washington, DC — Although its name may make many people think of flowers, the element germanium is part of a frequently studied group of elements, called IVa, which could have applications for next-generation computer architecture as well as implications for fundamental condensed matter physics.
New research conducted by Xiao-Jia Chen, Viktor Struzhkin, and Ho-kwang (Dave) Mao from Geophysical Laboratory at Carnegie Institution for Science, along with collaborators from China, reveals details of the element’s transitions under pressure. Their results show extraordinary agreement with the predictions of modern condensed matter theory.
Washington, DC—Formaldehyde, a poison and a common molecule throughout the universe, is likely the source of the solar system’s organic carbon solids—abundant in both comets and asteroids.
