Washington, DC, 15 April 2010- Single-crystal relaxor ferroelectrics are useful and fascinating systems, but understanding the inner workings of these complex materials has been very challenging. They have spatial and temporal heterogeneities over a range of length and time scales.
Washington, DC, 1 April 2010- Nanoscience is opening up a new window on materials under extreme conditions.
Washington, DC—Physicists have long wondered whether hydrogen, the most abundant element in the universe, could be transformed into a metal and possibly even a superconductor—the elusive state in which electrons can flow without resistance.
Single-crystal diamonds produced at the Geophysical Laboratory are traveling with a major museum exhibit called the Nature of Diamonds. The display focuses on the beauty of diamonds, their geological origins, and the science of diamond.
Washington, DC—The oil and gas that fuels our homes and cars started out as living organisms that died, were compressed, and heated under heavy layers of sediments in the Earth’s crust.
Argonne, IL—Millions of people today carry around pocket-sized music players capable of holding thousands of songs, thanks to the discovery 20 years ago of a phenomenon known as the “giant magnetoresistance effect,” which made it possible to pack more data onto smaller and smaller hard drives.
A discovery by scientists at the Carnegie Institution has opened the door to a new generation of piezoelectric materials that can convert mechanical strain into electricity and vice versa, potentially cutting costs and boosting performance in myriad applications ranging from medical diagnostics t
