Organic magnetoelectroluminescence for room temperature transduction between magnetic and optical information
Magnetic and spin-based technologies for data storage and processing provide unique challenges for information transduction to light because of magnetic metals' optical loss, and the inefficiency and resistivity of semiconductor spin-based emitters at room temperature. Transduction between magnetic and optical information in typical organic semiconductors poses additional challenges, as the spin-orbit interaction is weak and spin injection from magnetic electrodes has been limited to low temperature and low polarization efficiency.

Crystallization of the Earth’s inner core fractionates major and minor elements between the solid and liquid metal, leaving physical and geochemical imprints on the Earth's core. For example, the density jump observed at the Inner Core Boundary (ICB) is related to the preferential partitioning of lighter elements in the liquid outer core.

RICHLAND, WA - Geologic and soil processes are to blame for significant baseline levels of arsenic in soil throughout Ohio, according to a study published recently in the Journal of Environmental Quality. "The distribution of arsenic throughout Ohio appears to be the result of natural patterns," said first author Erik Venteris of the Department of Energy's Pacific Northwest National Laboratory, who was with the Division of Geological Survey of the Ohio Department of Natural Resources when the study was done.
