Washington, DC—Chemical compounds called manganites have been studied for many years since the discovery of colossal magnetoresistance, a property that promises important applications in the fields of magnetic sensors, magnetic random access memories and spintronic devices.

Geochemistry

Washington, DC—Surprising new research shows that, contrary to conventional belief, remains of chitin-protein complex—structural materials containing protein and polysaccharide—are present in abundance in fossils of arthropods from the Paleozoic era.

High Pressure

Washington, DC, 14 December 2010- Materials can take on surprising shapes under pressure.

Geochemistry, High Pressure

Argonne, ILL—For the first time scientists have been able to watch nanoparticles grow from the earliest stages of their formation. Nanoparticles are the foundation of nanotechnology and their performance depends on their structure, composition, and size.

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.
