High Pressure, Materials, Matter at Extreme States

Dhiren Pradhan is a postdoctoral associate working with Ronald Cohen. His works involve experiments on ferroelectrics, piezoelectrics, hyperferroelectrics and magnetoelectric materials.  He recently completed his Ph.D. in Chemical Physics from the University of Puerto Rico,USA.

High Pressure, Matter at Extreme States

Washington, DC—Recovered minerals that originated in the deep mantle can give scientists a rare glimpse into the dynamic processes occurring deep inside of the Earth and into the history of the planet’s mantle layer. A team led by the Geophysical Laboratory's Yingwei Fei, a experimental petrologist, and Cheng Xu, a field geologist from Peking University, has discovered that a rare sample of the mineral majorite originated at least 235 miles below Earth’s surface. Their findings are published by Science Advances.

High Pressure, Matter at Extreme States

Washington, DC— Although helium is the second most-abundant element (after hydrogen) in the universe, it doesn’t play well with others. It is a member of a family of seven elements called the noble gases, which are called that because of their chemical aloofness—they don’t easily form compounds with other elements. Helium, widely believed to be the most inert element, has no stable compounds under normal conditions.
