High Pressure, Materials

Washington, DC, 18 August 2010- Researchers from the University of Michigan and the Geophysical Laboratory have demonstrated a new method for quantitatively measuring the degree of pressure-induced atomic disordering in pyrochlore oxides using synchrotron x-ray diffraction, synchrotron infrared spectroscopy and Raman scattering techniques.

Washington, DC— Up to now scientists thought that the trace amounts of carbon on the surface of the Moon came from the solar wind. Now researchers at the Carnegie Institution’s Geophysical Laboratory have detected and dated Moon carbon in the form of graphite—the sooty stuff of pencil lead—which survived from the late heavy bombardment era 3.8 billion years ago.

Washington, DC—Scientists at the Carnegie Institution’s Geophysical Laboratory, with colleagues, have discovered a much higher water content in the Moon’s interior than previous studies.

Washington, DC — The evolution of complex life forms may have gotten a jump start billions of years ago, when geologic events operating over millions of years caused large quantities of phosphorus to wash into the oceans.

Washington, DC—An unprecedented study of bald eagle diet, from about 20,000 to 30,000 years ago to the present, will provide wildlife managers with unique information for reintroducing Bald Eagles to the Channel Islands off California.

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.

Metallic glasses are emerging as potentially useful materials at the frontier of materials science research. They combine the advantages and avoid many of the problems of normal metals and glasses, two classes of materials with a very wide range of applications.
High Pressure

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.
