Sandia Research Featured on Journal of Physical Chemistry A Cover

As part of Sandia’s core geochemistry program funded by DOE Office of Basic Energy Sciences (BES), Sandia’s Randall Cygan (in Sandia’s Geoscience Research and Applications Dept.) and his collaborators, W. Crawford Elliott and his PhD student Laura Zaunbrecher from Georgia State University, have been examining the adsorption mechanisms of metal cations onto soils and sediments. [...]

Sandia Participates in Office of Science’s National Science Bowl

The Department of Energy Office of Science’s National Science Bowl® (NSB) is a nationwide academic competition that tests middle and high school student teams’ knowledge in all areas of science and mathematics. The DOE created the National Science Bowl® in 1991 to encourage students to excel in mathematics and science and to pursue careers in [...]

Lignin-Feasting Microbe Holds Promise for Biofuels

Nature designed lignin, the tough woody polymer in the walls of plant cells, to bind and protect the cellulose sugars that plants use for energy. For this reason, lignin is a major challenge for those who would extract those same plant sugars and use them to make advanced biofuels. As part of their search for [...]

Jeff Tsao participates in “Energy Efficiency and the Rebound Effect” Workshop

June 27-28, 2011 [singlepic id=979 w=320 h=240 float=right] The rebound (or take-back) effect) is the term in energy economics used to describe the effectin which increases in energy efficiency do not necessarily lead to simple 1:1 decreases in energy consumption, but instead are “taken back” in the form of higher consumption of the goods and [...]

Four-color laser white illuminant demonstrating high color-rendering quality

July 4, 2011 [singlepic id=980 w=320 h=240 float=right]Solid-state lighting is currently based on light-emitting diodes (LEDs) and phosphors.  Solid-state lighting based on lasers would offer significant advantages including high potential efficiencies at high current densities. Light emitted from lasers, however, has a much narrower spectral linewidth than light emitted from LEDs or phosphors.  Therefore it [...]
